Topics for Today Site Leadership and Site Binder Safety Monitoring and Enforcement Safety Topics
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.
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.
Emergency Preparedness Safety Board First Aid Kit CPR & First Aid Training Fire Extinguishers Water Phone Contacts Job Site Address
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 days work plans and make crew assignments
Ad Hoc Orientation Be sure to interact with any volunteers who missed the Morning Orientation about the work tasks and safety issues discussed.
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.
Accident Claim Form (CHUBB) This form is used when there is an accident that requires medical attention
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
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.
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)
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 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.
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.
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.
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.
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.
Enforcement of Rules 1 st Violation – Safety Coaching 2 nd Violation – Additional Safety Coaching 3 rd Violation – suspension from jobsite (with site supervisor consultation)
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. Safety Coaching
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
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
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
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
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
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 Dont 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
Power Tools – Precautions Electric Cords Dont carry portable tools by the cord Dont use electric cords to hoist or lower tools Dont yank cord or hose to disconnect it Keep cords and hoses away from heat, oil, and sharp edges
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 Electric Power Tools Double insulated markings Plug with a grounding pin
Electric Tools – Good Practices Operate within design limits Use gloves and safety glasses Store in a dry place Dont use in wet locations unless approved for that Keep work areas well lit Ensure cords dont present a tripping hazard
The point of operation is where the work is actually performed on the materials – it must be guarded Guarding - Point of Operation This shows a radial arm saw equipped with proper point of operation guards
Guard these saws above and below the base plate or shoe. The lower guard must cover the saw to the depth of the teeth. Guarding Portable Circular Saws
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
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
Its Just Electricity Most people assume that electrical power is relatively harmless – Yet many people are killed each year – Most deaths involve 110 volt power
Temporary Power Electrical shocks due to temporary power and cords can be controlled by – Ground Fault Circuit Interrupters (GFCI) – Covers on electrical equipment
GFCI Systems GFCIs dont eliminate electrical shock, – They reduce the magnitude and duration At 5 milliamps (mA) or less (Magnitude) In 1/40 th of 1 second(Duration) – They terminate the flow of electricity
Dry vs Wet and Ohms Law If our body is wet the electrical resistance is approximately 1000 Ohms Under Ohms Law 120/1000 Ohms equals 120 mA and is enough to cause ventricular fibrillation
GFCI Systems When GFCIs trip repeatedly, the cause is often equipment related Extension cords often have internal damage, that allow ground faults
GFCI Systems Replacing the GFCI will not fix the problem – Replace the damaged tool or cord
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 GFCIs can be wired incorrectly
Overhead Power Regulations require we stay 10 feet or more from overhead power lines This includes; – Ladders – Backhoes – Forklifts – Cranes – Concrete pump trucks
Overhead Power The power company will provide grounding and barriers or blankets to cut off power when requested
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 Hazards Improper use of the top rung of a step ladder
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 used on a construction site Slips, Trips and Falls On Stairways and Ladders
There must be a stairway or ladder at points of access where there is a break in elevation of 19 inches or more. General Requirements
When toprail of stairrail is also the handrail it must be between 36 & 37 inches high measured from the front of the stair tread 36" - 37" Stairrail vs. Handrail
Rails must be able to withstand a force of 200 pounds Handrail and Top Rail Strength
Handrails Stairways with four or more risers, or higher than 30 inches, must be equipped with at least one handrail.
Stairways with four or more risers or more than 30 inches high must have a stairrail along each unprotected side or edge. Stairrails
Install between 30 and 50 degrees. Must have uniform riser height and tread depth, with less than a 1/4-inch variation. Uniform - 30 & 50 degree angle No more than 1/4 inch variation in any stairway system Stairs
Dangerous Conditions Fix slippery conditions before using. Stairway parts must be free of obstructions which may cause injuries or snag clothing.
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 General Ladder Requirements
Use ladders only for their designed purpose -- DONT – 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 manufacturers rated capacity Use step ladders as extension ladders General Ladder Requirements
Securing Ladders 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 This ladder is not on a stable surface
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 Job Built Ladders
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
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 Ladder Rail Extension
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. This is an unsafe condition
Do NOT use the top or top step of a stepladder as a step Top Step
Do NOT use crossbracing on the rear of a stepladder for climbing - unless the ladder is designed for that On this ladder the back rungs are designed for use Crossbracing
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. Damaged or Defective Ladders Missing rung
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. Climbing the Ladder
Summary Key Components for Stairway Safety Treads Rails handrails stair rails guardrails Landings and Platforms
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.
