1 Construction Site Operations Training

2 Topics for Today Site Leadership and Site Binder
Safety Monitoring and Enforcement Safety Topics

3 Morning Planning Meeting
House Leader, House Lead Assistant and Crew Leaders meet at the site approximately 30 minutes prior to the scheduled arrival of the other volunteers.

4 Morning Planning Meeting
Plan the day's work, adjusting for site conditions, weather, etc. Discuss technical aspects, materials, tools and locations of the materials and tools. Assess hazards, safety issues, and preventative measures. Choose which sections of the “Safety Huddle Booklet” will be reviewed, using the “Safety Huddle Report”. Make a thorough hazard assessment and make sure that the site is designed for safety and efficiency

5 Emergency Preparedness
Safety Board First Aid Kit CPR & First Aid Training Fire Extinguishers Water Phone Contacts Job Site Address Items that volunteers will need to know location or information. Describe what Safety Board is. Make sure address is posted.

6 Safety Huddle Report Information to provide and checklist of topics to cover during safety huddle.

7 Safety Huddle Booklet Guide for reviewing General Safety Precautions and the precautions specific to each phase of construction

8 Volunteer Sign In Make sure volunteers fill in the form completely and legibly.

9 Waiver of Liability Each volunteer needs to sign a waiver on an annual basis.

10 Waiver of Liability for Minors
Waiver specific to minors which also needs to be signed by their parent or guardian.

11 Job Site Youth Policy Some main points:
Must be 16 to be on a construction site. Must be 18 to use power tools. Must be 18 to do roofing or activities involving heights on ladders or scaffolding

12 Sweat Equity Not in the site binder, partner families bring this form and turn them in to Family Services. Sign the homeowner’s sweat equity form at the end of the day when they leave.

13 Summary of Daily Morning Orientation
Have volunteers sign in and complete waivers. Pray and provide general Habitat overview. Location of drinking water, Safety Board, first aid kit and fire extinguisher Identify volunteers with first aid and/or safety training or experience. Review the appropriate sections of the Safety Huddle Booklet. Discuss the day’s work plans and make crew assignments

14 Ad Hoc Orientation Be sure to interact with any volunteers who missed the Morning Orientation about the work tasks and safety issues discussed.

15 Work Site Audit Use the Work Site Audit Form every day to audit the safety conditions and practices at the work site. These audits provide feedback to the HFHGC Safety Committee on the effectiveness of the HFHGC Safety Process.

16 Work Site Audit Form Is safety equipment in good working order?
Is PPE provided and in good condition? Have job site safety hazards been addressed? Are tools, equipment and cords in good working condition?

17 Accident Investigation

18 Accident Investigation Report
Read accident definition: Remember: An accident is defined as an undesirable or unfortunate incident that occurs unexpectedly or unintentionally and can result in injury, damage, or loss. This form is to be used any time there is an accident. This form is used by the safety committee to review accidents and make improvements to the safety program.

19 Accident Claim Form (CHUBB)
This form is used when there is an accident that requires medical attention This form is used when there is an accident that requires medical attention.

20 Completed Forms Keep completed site and safety forms in the yellow folder in the site binder The Site Supervisor will collect these forms on a regular basis

21 Maintaining the Mobile Mini
Having the tools and materials organized inside the Mini helps keep the job running efficiently. The Mini itself can become a safety hazard-keep a clear path and make sure tools and materials are secured from falling. Keep Valuable Tools inside the Mini overnight, not in the house. Utilize volunteers that are excited about organization to help with this.

22 Safety Monitoring and Enforcement

23 Matthew 7:12 (paraphrased)
Safety First A Good Carpenter once told his crew, "Consider the safety of others on the work site as you would have them consider your safety“. Matthew 7:12 (paraphrased) Safety is an attitude and requires a team effort.

24 A Responsibility to Safety
All employees and volunteers have the responsibility to follow the guidelines and information in the safety manual and to work safely while on a HFHGC job site. Safety is also a responsibility.

25 Safety Training Provide the best possible information and preparation to everyone on site. By providing the safety and awareness training and monitoring work sites, HFHGC can continue to provide housing for families in need and make volunteer experiences memories that will last a lifetime.

26 Promotion and Monitoring
Continually promote safety awareness and coach all volunteers to ensure adherence to all safety checklists and safe practices throughout the site at all times.

27 Roles & Responsibilities
House Leaders are responsible for implementing and enforcing safety requirements on the work sites. House Leaders, House Lead Assistants and Crew Leaders have the responsibility to provide coaching to volunteers about safe work practices. Individuals who are unwilling to respond to this coaching will be asked to leave the worksite. Any controversies that result from this request will be addressed by the HFHGC Volunteer Director, and/or the HFHGC Construction Director.

28 Things to Keep in Mind Most volunteers are novices who work only once or a small number of times. Never be in a hurry, take as much time as is needed to provide safety training and work technique guidance. Safety training must be augmented throughout the day with reinforcement by a small number of more experienced and/or trained volunteers. Encourage volunteers to drink plenty of water and to use sunscreen as needed.

29 Safety Equipment All equipment, tools, their associated safety devices and guarding are in good working order at all times. Safety glasses 100%. Hard hats 100% prior to drywall finish, thereafter as needed.

30 Enforcement of Rules 1st Violation – Safety Coaching
2nd Violation – Additional Safety Coaching 3rd Violation – suspension from jobsite (with site supervisor consultation)

31 Safety Coaching Safety Coaching is provided to individuals when it is observed that there is either an unsafe condition or an unsafe act that needs to be brought to their attention. Be sure to provide coaching remarks in terms of the risk to which they may be exposed while correcting the unsafe condition or act. It is best to provide safety coaching in a positive way to the person or persons at risk.

32 Personal Protective Equipment

33 Personal Protection Equipment
No loose clothing Long hair tied back or put up Sturdy shoes: hard soled, NO open toe or sandals

34 Personal Protective Equipment
Hardhats Worn when there is any overhead hazard, 100% of the time prior to drywall finish. Hardhat shells and liners have expiration dates on them. Shells last five years. Liners last two years. Demonstrate how to assemble a hard hat.

35 Personal Protective Equipment
Eye Protection 100% of the Time

36 Personal Protective Equipment
Hearing Protection Recommended for person running power tools for a long period of time The “cut person” should definitely wear hearing protection.

37 Personal Protective Equipment
Hand Protection As required/necessary

38 Hand & Power Tools

39 Hazards Workers using hand and power tools may be exposed to these hazards: objects that fall, fly, are abrasive, or splash harmful dusts, fumes, mists, vapors, and gases frayed or damaged electrical cords, hazardous connections and improper grounding Hand and power tools are a part of our everyday lives. These tools help us to perform tasks that otherwise would be difficult or impossible. However, even simple tools can be hazardous, and have the potential for causing severe injuries when used or maintained improperly. Special attention toward hand and power tool safety is necessary in order to reduce or eliminate these hazards.

40 Basic Tool Safety Rules
Maintain on a regular basis Use right tool for the job Inspect before use Operate according to manufacturers’ instructions Use the right personal protective equipment (PPE) Use safety guards

41 Hand Tool Hazards Hazards are usually caused by misuse and improper maintenance Do not use: wrenches when jaws are sprung impact tools (chisels and wedges) when heads have mushroomed tools with loose, cracked or splintered handles a screwdriver as a chisel tools with taped handles – they may be hiding cracks Crack • If a screwdriver is used as a chisel, the tip of the chisel may break and fly off, hitting the user or other employees. • If a wooden handle on a tool, such as a hammer or an axe is loose, splintered, or cracked, the head of the tool may fly off and strike the user or other employees. • If the jaws of a wrench are sprung, the wrench might slip. • If impact tools, such as chisels, wedges, or drift pins have mushroomed heads, the heads might shatter on impact, sending sharp fragments flying toward the user or other employees.

42 Hand Tools - Protection
Use PPE, such as safety goggles and gloves Keep floor surface where working free from debris and tripping or slipping hazards Keep cutting tools sharp

43 Power Tools Must be fitted with guards and safety switches
Extremely hazardous when used improperly Different types,determined by their power source: Electric Pneumatic Liquid fuel Hydraulic Powder-actuated (b) and

44 Power Tools - Precautions
Disconnect tools when not in use, before servicing and cleaning, and when changing accessories Secure work with clamps or a vise, freeing both hands to operate the tool Don’t hold the switch button while carrying a plugged-in tool Keep tools sharp and clean Consider what you wear – loose clothing and jewelry can get caught in moving parts Remove damaged electric tools & tag them: “Do Not Use” Examples: 1) Unplug saws when changing blades. 2)Use clamps to secure materials to saw horses or miter saw. 3)If a circular saw is being pushed through wood instead of allowing the blade to cut through the wood, the blade probably needs replaced. There will be “Do Not Operate” tags in the Mini Mobile.

45 Power Tools – Precautions Electric Cords
Don’t carry portable tools by the cord Don’t use electric cords to hoist or lower tools Don’t yank cord or hose to disconnect it Keep cords and hoses away from heat, oil, and sharp edges (a)(2)

46 Electric Power Tools To protect a worker from shock, these tools must:
have a 3-wire cord plugged into a grounded receptacle be double insulated, or be powered by a low-voltage isolation transformer (a)(1) Three-wire cords contain two current-carrying conductors and a grounding conductor. Any time an adapter is used to accommodate a two-hole receptacle, the adapter wire must be attached to a known ground. The third prong must never be removed from the plug. Double-insulated tools are available that provide protection against electrical shock without third-wire grounding. On double-insulated tools, an internal layer of protective insulation completely isolates the external housing of the tool. Plug with a grounding pin Double insulated markings

47 Electric Tools – Good Practices
Operate within design limits Use gloves and safety glasses Store in a dry place Don’t use in wet locations unless approved for that Keep work areas well lit Ensure cords don’t present a tripping hazard When using gloves, make sure they will not cause an amputation hazard by becoming loose clothing.

48 Guarding - Point of Operation
This shows a radial arm saw equipped with proper point of operation guards (b)(4) and (g) The guarding device shall be designed and constructed to prevent the operator from having any part of his body in the danger zone during the operating cycle. The point of operation is where the work is actually performed on the materials – it must be guarded

49 Guarding Portable Circular Saws
Guard these saws above and below the base plate or shoe. The lower guard must cover the saw to the depth of the teeth. (d) The upper guard shall cover the saw to the depth of the teeth, except for the minimum arc required to permit the base to be tilted for bevel cuts. The lower guard shall cover the saw to the depth of the teeth, except for the minimum arc required to allow proper retraction and contact with the work. When the tool is withdrawn from the work, the lower guard shall automatically and instantly return to the covering position. GRAPHIC The graphic depicts a portable saw where the worker is holding the bottom guard up to demonstrate how it slides up as the blade comes in contact with the material being cut.

50 Table Saw Guarding Hood guard
(h)(1) Hand-fed crosscut table saws Each circular crosscut table saw shall be guarded by a hood

51 Liquid Fuel Tools Usually gasoline powered Main hazard – fuel vapors
Use only approved flammable liquid containers Before refilling a fuel-powered tool tank, shut down the engine and allow it to cool (c) If using a fuel powered tool in an enclosed area such as a trench, be aware that carbon monoxide generated can displace or deplete oxygen. Mechanical ventilation and testing needs to be done.

52 Summary Hazards are usually the result of improper tool use or not following one or more of these protection techniques: Inspecting the tool before use Using PPE (Personal Protective Equipment) Using guards Properly storing the tool Using safe handling techniques

53 Electrical Safety

54 It’s Just Electricity Most people assume that electrical power is relatively harmless Yet many people are killed each year Most deaths involve 110 volt power

55 Temporary Power Electrical shocks due to temporary power and cords can be controlled by Ground Fault Circuit Interrupters (GFCI) Covers on electrical equipment

56 GFCI Systems GFCI’s don’t eliminate electrical shock,
They reduce the magnitude and duration At 5 milliamps (mA) or less (Magnitude) In 1/40th of 1 second (Duration) They terminate the flow of electricity

57 Dry vs Wet and Ohms Law If our body is wet the electrical resistance is approximately Ohms Under Ohms Law 120/1000 Ohms equals 120 mA and is enough to cause ventricular fibrillation Note the water faucets run by the plumber in the electrician’s ditch. Instead of putting the water half-way between electrical stations, the plumber put them all together. Remember that water and electricity don’t mix!

58 GFCI Systems When GFCI’s trip repeatedly, the cause is often equipment related Extension cords often have internal damage, that allow ground faults If a GFCI does trip repeatedly, make sure that all cords and tools being used are not damaged.

59 GFCI Systems Replacing the GFCI will not fix the problem
Replace the damaged tool or cord

60 GFCI Systems GFCI systems must be tested DAILY before use
Use the test button on the device Use a tool to assure the power stops GFCI’s can be wired incorrectly Notice that the RESET button is tripped, or out. Also notice that the inductive voltage tester is still showing power to the receptacles. This can only happen when the GFCI is wired incorrectly. Demonstrate use of a GFCI tester.

61 Overhead Power Regulations require we stay 10 feet or more from overhead power lines This includes; Ladders Backhoes Forklifts Cranes Concrete pump trucks

62 Overhead Power The power company will provide grounding and barriers or blankets to cut off power when requested If there is an issue let the site supervisor know.

63 Stairway & Ladder Safety

64 What NOT to Do

65 What NOT to Do Buckets are not OSHA approved for climbing.

66 What NOT to Do

67 Hazards Stairways and ladders cause many injuries and fatalities among construction workers About half the injuries caused by slips, trips and falls from ladders and stairways require time off the job Reference – OSHA Publication 3124, Stairways and Ladders Improper use of the top rung of a step ladder

68 Slips, Trips and Falls On Stairways and Ladders
At the end of this training, you should be able to list or describe: Safety guidelines and requirements for stairways used on a construction site Safe practices and requirements for ladders

69 General Requirements There must be a stairway or ladder at points of access where there is a break in elevation of 19 inches or more. Reference (a) A stairway or ladder shall be provided at all personnel points of access where there is a break in elevation of 19 inches (48 cm) or more, and no ramp, runway, sloped embankment, or personnel hoist is provided. Point of access - All areas used by employees for work-related passage from one area or level to another. An example for our builds is the elevation from the ground to the porches before the concrete steps are poured. Since it’s greater than 19” we build temporary stairs.

70 Stairrail vs. Handrail 36" - 37" When toprail of stairrail is also the
When the top edge of a stairrail system also serves as a handrail, the height of the top edge shall be not more than 37 inches (94 cm) nor less than 36 inches (91.5 cm) from the upper surface of the stairrail system to the surface of the tread, in line with the face of the riser at the forward edge of the tread. When toprail of stairrail is also the handrail it must be between 36 & 37 inches high measured from the front of the stair tread

71 Handrail and Top Rail Strength
Rails must be able to withstand a force of 200 pounds Reference (c)(5) Handrails and the top rails of the stairrail systems must be capable of withstanding, without failure, at least 200 pounds of weight applied within 2 inches of the top edge in any downward or outward direction, at any point along the top edge.

72 Handrails Stairways with four or more risers, or higher than 30 inches, must be equipped with at least one handrail. Reference (c) Handrails must provide an adequate handhold for employees to grasp to prevent falls. Temporary handrails must have a minimum clearance of 3” between the handrail and walls, stairrail system and other objects. OSHA has specific height requirements for handrails. Check the standard to ensure these are met during installation of handrails, stairrails and guardrails

73 Stairrails Stairways with four or more risers or more than 30 inches high must have a stairrail along each unprotected side or edge. Reference (c) All stairways of 4 steps or more must have a handrail. If there is a fall hazard of 6 feet or more on an exposed side of the stairs, then a stairrail system must be provided to prevent workers from falling off the side. Explain quantity of risers.

74 variation in any stairway system
Stairs Uniform - 30 & 50 degree angle Install between 30 and 50 degrees. Must have uniform riser height and tread depth, with less than a 1/4-inch variation. No more than 1/4 inch variation in any stairway system Reference (a)(3) and (a)(2)

75 Dangerous Conditions Fix slippery conditions before using.
Stairway parts must be free of obstructions which may cause injuries or snag clothing. Reference (a)(7) and (a)(6) In addition to the components of a stair system, it is important to address other potentially dangerous conditions such as slippery stairs, rails or landings due to weather conditions or the composition of the stair material (e.g. smooth, metal surfaces). Note: Scrap shingles are good for slip resistance.

76 Ladders

77 General Ladder Requirements
Ladders must be kept in a safe condition -- DO – Keep the area around the top and bottom of a ladder clear Ensure rungs, cleats, and steps are level and uniformly spaced Ensure rungs are spaced 10 to 14 inches apart Keep ladders free from slipping hazards Reference (a) and (b)

78 General Ladder Requirements
Use ladders only for their designed purpose -- DON’T – Tie ladders together to make longer sections, unless designed for such use Use single rail ladders Load ladders beyond the maximum load for which they were built, nor beyond the manufacturer’s rated capacity Use step ladders as extension ladders Reference (a) and (b)

79 Securing Ladders This ladder is not on a stable surface
Secure ladders to prevent accidental movement due to workplace activity Be sure ladders are on stable and level surfaces or leg levelers are used. Do not use ladders on slippery surfaces unless provided with slip-resistant feet Reference (b)(8), (b)(6), (b)(7), and (b)(1) Ladders placed in areas such as passage-ways, doorways, or driveways, or where they can be displaced by workplace activities or traffic must be secured to prevent accidental movement, or a barricade must be used to keep traffic or activities away from the ladder. This ladder is not on a stable surface

80 Job Built Ladders Inspect before use for cracks, dents, and missing rungs Design or treat rungs to minimize slipping Side rails -- at least 11 1/2 inches apart Must support 4 times the maximum load Reference (b)(15), (b)(6)(ii) and (a)(4)(ii) See the OSHA web site at: Portable Ladder: a ladder that can be readily moved or carried. Ladder rungs, cleats, and steps must be parallel, level and uniformly spaced. The rungs and steps of portable metal ladders must be corrugated, knurled, dimpled, coated with skid-resistant material or treated to minimize slipping.

81 Ladder Angle Non-self-supporting ladders:
(which lean against a wall or other support) Position at an angle where the horizontal distance from the top support to the foot of the ladder is 1/4 the working length of the ladder Reference (b)(5) Working length of ladder – Distance along the ladder between the foot and top support Rule of thumb: If you’re standing with your feet at the base of the ladder, you should be able to hold your arms straight out and hold on to the ladder.

82 Ladder Rail Extension When using a portable ladder for access to an upper landing surface, the side rails must extend at least 3 feet above the upper landing surface Also, be sure to secure the ladder at the top keep it from moving. Reference (b)(1) When portable ladders are used for access to an upper landing surface, the side rails must extend at least 3 feet above the upper landing surface. When such an extension is not possible, the ladder must be secured, and a grasping device such as a grab rail must be provided to assist workers in mounting and dismounting the ladder. A ladder extension must not deflect under a load that would cause the ladder to slip off its support.

83 Near Energized Electrical Equipment
If using ladders where you or the ladder could contact exposed energized electrical equipment, you must have nonconductive siderails such as wood or fiberglass. Reference (b)(12) This is an unsafe condition

84 Top Step Do NOT use the top or top step of a stepladder as a step
Reference (b)(13)

85 Crossbracing Do NOT use crossbracing on the rear of a stepladder for climbing - unless the ladder is designed for that Reference (b)(14) A metal spreader or locking device must be provided on each stepladder to hold the front and back sections in an open position when the ladder is being used. On this ladder the back rungs are designed for use

86 Damaged or Defective Ladders
A competent person must inspect ladders for visible defects, like broken or missing rungs If a defective ladder is found, immediately mark it defective or tag it "Do Not Use”. Withdraw defective ladders from service until repaired. Missing rung Reference (b)(16) Ladders must be inspected on a periodic basis and after any incident that could affect their safe use. Ladder components must be surfaced to prevent injury from punctures or lacerations and prevent snagging of clothing.

87 Climbing the Ladder Face the ladder when going up or down.
Use at least one hand to grab the ladder when going up or down. Do not carry any object or load that could cause you to lose balance. Reference (b)(20),(21),(22)

88 Key Components for Stairway Safety
Summary Key Components for Stairway Safety Treads Rails handrails stair rails guardrails Landings and Platforms

89 Key Components for Ladder Safety
Summary Key Components for Ladder Safety A competent person must inspect ladders for damage. Use the correct ladder for the job. Use the correct angle, supports, treads, cross braces and rails. Do NOT overload. Volunteers must be trained in proper use of a ladder.

90 Fall Protection First the overview….
Begins with “Why it’s the #1 concern” and then goes into an outline of the issues/options

91 Why is fall protection important?
Prevents or reduces personal injury Prevents/reduces injury to others Compliance with the regulations

92 Fall Protection Topics
The importance of planning When fall protection is required What fall protection methods are available Training

93 Duty to Have Fall Protection
Fall protection must be provided when individuals are exposed to the hazard of falling six feet or more….. through holes through wall openings from established floors, mezzanines, balconies, & walkways into excavations

94 Planning and Identifying Needs
Evaluate the work site Identify fall hazards Identify who is exposed to fall hazards Evaluate the process to be done and the needs to complete the task Identify what method of fall protection will be used for each hazard identified

95 How much planning was done here?

96 Fall Protection Standards
Fall Restraint and Fall Arrest when there is a hazard of falling from a location 10 feet or more in height Floor Openings, Wall Openings and Stairways when there is a hazard of falling from a walking/working surface 6 feet or more in height

97 Now the details…. What gets people hurt How to prevent that
Where to check on things

98 Floor Openings Typical of what shows up in residential construction.
The worst part of this hazard is that if/when a person falls into the opening, they’re tipping over and will usually land on their head or shoulder. These cause deaths or life-limiting injuries on a regular basis.

99 Floor Openings An opening 12” or more in its least dimension in any floor, roof or platform through which persons may fall. Definition

100 Covers Must be capable of supporting, without failure, at least 2X the weight of employees, equipment, and materials that may be imposed on the cover at any one time Must be secured to prevent accidental displacement by the wind, equipment, or employees Must be color coded or marked “HOLE” or “COVER”

101 Wall Openings An opening at least 30” high and 18 wide in any wall or partition through which persons may fall…. Definition.

102 Wall Openings At least 30” high and 18” wide
Must be guarded when drop is more than 6’ and Bottom of opening is less than 3’ above working surface.

103 Wall Openings Guardrail
And so he’s putting up a guard. Not a terribly complex, time-consuming job. Well worth the effort. Guardrail

104 Height Minimum height of 42” plus/minus 3”, EXCEPT:
The top rail of a guardrail is specified at 42 inches (plus or minus three) from the working surface. If the volunteer is up on a stepladder, what is the height of their working surface? What’s the result of adding 42 inches to that?

105 Stairways This is how an inspector documented the situation.

106 Guardrail Systems Toprail at 42” (+/- 3”) from working surface
Midrail approx. 21”, or screens/mesh from toprail to working surface Capable of withstanding 200 lbs. of force (midrail must withstand 150 lbs.) applied within two inches of the top edge

107 Stairways “Standard guardrail” top rail, midrail, toeboard, posts
Will this pass the strength test? Probably.

108 Ramps Where there is a break in elevation of 18” or more
Minimum 18” wide Not more than 20o from horizontal Cleated or treated to prevent slipping Guardrails if more than 6’ from surface Another area where many Habitat projects create hazards for volunteers. Consider the amount of foot traffic in and out of a house on a busy day! What are some options for “…treating..” the ramp against slipping? Scrap shingles are good out here where we get so much rain.

109 “Open Sided Platform” Again, the basic measurement: 6’ trigger height
This was actually worse than it looked. 20 feet below the guy on the skimpy little plank was a forest of exposed rebar. He was creeping along – visibly nervous – when the inspector snapped the photo. She didn’t get out of the car until he was over onto the deck; didn’t want to break his concentration and cause a fall!

110 “Trigger Height” 6 feet is default
May be zero if above/adjacent to dangerous equipment, chemicals, other hazards Again: important to distinguish between the strict letter of the law requirement and what you want to do to protect your volunteers.

111 6’ “Trigger Height” Open sided surfaces, window openings and stairs have to be guarded when the fall exposure is 6’ or greater.

112 What’s Wrong With This Picture?
Another factor: Corollary to Murphy’s Law – given a history of negative outcomes, people come to assume an activity is safe. In other words, he’s never been hurt doing this (obviously) so he believes that it’s perfectly safe for himself.

113 Hazard? Area should be clean to prevent tripping hazards.
The falling hazard is generally presumed to come from the worker’s focusing on a task and not paying attention to where he/she is going. “Housekeeping” adds another major source of falling.

114 Hazard? A common problem: a stepladder propped up against the sill for access. It’s both awkward and a bottleneck. The solution is in the scheduling. They’ll have to put in the porch/stairs eventually. Why not schedule it earlier to make the job site safer? And one more case where safety doesn’t cost a thing extra. It just takes some thought.

115 Hazard?

116 Slide Guards Installed under Competent Person supervision
Cannot be used as fall protection on roofs with ground/eave height of 25 ft. or more Cannot be used as fall protection on roofs with a slope less than 3:12 nor greater than 8:12 Roofs with slopes greater than or equal to 3:12 to and including 6:12 minimum of one slide guard placed below the work area no closer than 6” from the eave

117 Slide Guards Roofs with slopes greater than 6:12 to and including 8:12
multiple slide guards must be used spaced 8’ apart, vertically lower slide guard must be placed no closer than 6” from eave Lowest slide guard must be 90 degrees to the roof surface

118 Slide Guards

119 Manufactured Roof Brackets
Slide Guard Systems – Manufactured Roof Brackets Installed according to manufacturer’s specs Minimum 6” brackets must be used All brackets must bear on a solid surface Brackets must not be spaced greater than 8’ apart horizontally, or according to manufacturer’s specs (whichever is less) The instructions on the roof brackets we use say to use “20 penny” nails.

120 Manufactured Roof Brackets
Slide Guard Systems – Manufactured Roof Brackets Nominal 2”X6” material must be used for slide guards must be secured to the brackets or otherwise protected against cantilevering and failure due to material flex

Notes: This manual is a product of the U.S. Department of Labor, Occupational Safety and Health Administration. This guide was created to help the residential construction industry more easily understand the OSHA pump jack and ladder jack standards. Home builders in the west suburban Chicago area told us they had difficulty understanding the scaffold regulations, giving rise to the idea of using photos to communicate the regulations. The photo compliance guide walks the reader through the OSHA pump jack and ladder jack regulations, standard by standard. Thanks go to Aurora Area Office compliance staff Bay Pahati, Dave Morgan, John Maronic, John "Nuke" Newquist for the photographs. Special recognition is given to Nuke for scanning the photos and putting this information together. We strongly encourage the reproduction and use of this document!

122 Distance from Wall The walkboard should be no more than 14” from Wall
14 inches to the post does not give 14 inches to platform edge. The pipe is 2” diameter. Gap is therefore 16”

123 Pump Jack Set Up Footing shall be level, sound, rigid, and capable of supporting the loaded pump jack/walkboard without settling or displacement. Note: Use 3/4 inch plywood at least 12 x 12 inch wide and center the leg in the middle. The plywood should be staked in the ground and the leg secured from lateral movement Pumpjack Photo: John Maronic (wording removed from slide: “Violation: Pieces of scrap lumber used as footing does not provide adequate support.”)

124 Pump Jack Set Up Note: Strapping was used to hold platforms together. Pumpjack Photo: John Newquist Each walk platform shall extend over its end support at least 6 inches.

125 Pump Jack Set Up Safe access shall be provided to walkboard.
Ladder arranged so that worker can step onto walkboard directly from the ladder. Note: Fall protection is deficient, no mid rails. Pumpjack Photo: John Maronic

126 Pump Jack Set Up Guardrails are required at all open sides and ends of walkboard. Ends are not guarded on this narrow walkboard. Note: Nailing guardrails onto wood poles is not practical for siding. Pumpjack Photo: John Newquist

127 Pump Jack Set Up Pump jack poles shall be secured to the structure at the top by the use of rigid triangular bracing or equivalent. Pumpjack Photo: Bay Pahati

128 Pump Jack Set Up Pump jack poles shall be secured to the structure at the bottom by the rigid triangular bracing or equivalent. . Pumpjack Photo: John Newquist

129 Pump Jack Set Up Workbench may be used as a top rail if it meets the requirements for guardrails. Note: Platform must be secured to meet guardrail strength of 200 lbs. Pumpjack Photo: John Newquist (Wording removed from slide: “No violation: Platform vertical distance is 24 inches + 4 inch thick bench + 12 inch horizontal work bench distance = 40 inches for equivalent top rail protection. 24 inch gap is acceptable midrail opening.”)

130 Ladder Jack Set Up Walk platform must be within 14 inches to the structure. Safe access to the walkboard shall be provided Note: Access is poor. Ladder jack Photo: Bay Pahati

131 Ladder Jack Set Up Safe access shall be provided to walkboards over 2 feet in height. Ladderjack access ladder is set up so that worker steps from ladder to plank with no interference. Note: Worker wearing body harness with rope grab. Anchorage strength must meet (d). Rope grab should be adjusted to eliminate swing hazard. Ladder jack Photo: John Newquist

132 Ladder Jack Set Up Ladder jack platforms shall not be bridged one to another. Both metal planks should not be resting on a single ladder jack bracket. Scaffolds - 4 Type: Ladder jack scaffold

133 Ladder Jack Set Up Ladders must be used on level surfaces and secured to prevent displacement. Ladder feet are not stable on a sloped roof. Note: Ladder could have slideguard to prevent slipping. Ladder jack Photo: John Newquist

134 To Summarize Providing effective fall protection is not optional
