1 1 QHSE Department Presentation Working At Heights Fall Protection

2 2 INTRODUCTION Workers must be protected using fall restraint, personal fall arrest systems and safety net system Employee must be 100% tied off at all times Review Hazard Analysis & Risk Control and or JSA prior to working at height Obtain permit to work when necessary.

3 3 Why Use Fall Protection ?

4 4 When do you need fall protection? Fall protection is required anytime workers are exposed to a potential 5 (1.5 m) fall. Greater than 1.5m or 5 FALL PROTECTION

5 5 RESPONSIBILITIES It shall be the responsibility of the Supervisors to recognize fall hazards and to provide all necessary approved Fall Protection Equipment for employees use whenever deemed necessary It will also be the responsibility of the supervisor to provide required Fall Protection Training for their employees so that workers will possess enough knowledge to implement fall protection techniques in an effort to reduce the risk of injury due to fall

6 6 RESPONSIBILITIES Workers should be knowledgeable of: the nature of fall hazards in the work place correct procedures for erecting, maintaining, disassembling, and inspecting the fall protection systems used the use and operation of guardrail systems, personal fall arrest systems, safety net systems, and other protection to be used

7 7 RESPONSIBILITIES Workers should be knowledgeable of: the limitations on the use of mechanical equipment, and the correct procedures for handling and storage of equipment and materials and the erection of overhead protection dealing with the rescue of an employee after a fall arrest

8 8 RESPONSIBILITIES It will be the responsibility of the employee to follow Fall Protection Procedures and Techniques given them, and to assure all equipment used for fall protection is well maintained

9 9 WHAT IS FALL PROTECTION Hazard Elimination Traditional Fall Protection Fall Restraint Systems Fall Arrest Systems Work Procedures

10 10 HAZARD ELIMINATION Ideas, procedures, equipment or new technology that eliminates the need for a person to be at height.

11 11 TRADITIONAL FALL PROTECTION Physical barriers between worker and fall hazard. Primary & Secondary Systems Examples: - Guardrails - Catwalks ( with guard rails) - Gates and chains - Grates and covers - Man lifts

12 12 TRADITIONAL FALL PROTECTION Fall Restraint System Prevents the fall from occurring. Stops the fall after it has occurred. Changes in behavior can be made through education.

13 13 Any system in which a fall may occur ! User must consider: -Impact Force -Clearance -Swing Fall -Suspension after fall -Rescue -System Performance FALL ARREST SYSTEMS

14 14 Anchorage Connecting Means Body Support Device Shock Absorbing Lanyard Rescue and/or Escape Plan FALL PROTECTION SYSTEMS

15 15 Anchorages used for attachment of personal fall arrest equipment must withstand at least 5000 lbs. (22.2 kN) for each person attached, or shall be designed as follows: (i) as part of a complete personal fall arrest system which maintains a safety factor of at least two, and (ii) under the supervision of a qualified person. ANCHORAGE STRENGTH

16 16 ENGINEERED ANCHORS Little doubt exists when anchor points are engineered NEVER use home made anchor points

17 17 TEMPORARY ANCHORS There will always be a need for make-shift anchorages. End-users must exercise good judgment in selecting anchorages that are strong enough and in the correct location. A qualified person should be consulted if an anchor is in question.

18 18 ANCHOR STRAP Consider location and strength when selecting anchorages.

19 19 SNAP HOOKS shall be a locking type snap hook designed and used to prevent disengagement of the snap hook by contact of the snap hook keeper by the connected member.

20 20 Snap hooks shall be double / triple locking and sized to be compatible with anchorages to prevent roll-out. Recognize anchor / connector relationship ! SNAP HOOKS

21 21 CARABINERS Self-locking carabiners should be used to reduce misuse. The odds of a self- locking carabiner rolling open is less likely than a manually operated carabiner being left open.

22 22 Non-locking hooks and connectors are not acceptable ! Compatibility with other connectors and components is unknown. Consult a qualified person if shackles or other links are required. CARABINERS

23 23 ENERGY ABSORBING LANYARDS Lanyards are used to connect to the anchor strap. Flat webbing lanyards are the most commonly used.

24 24 ANSI Specifications: ANSI Specifications: 5000 lbs. MBS after testing lbs. MBS after testing. MAF shall not exceed 900 lbs. MAF shall not exceed 900 lbs. Max. 42 inch elongation. Max. 42 inch elongation. ENERGY ABSORBERS Energy absorbers reduce impact force to the body by deforming and adding stopping distance.

25 25 Rescue Plan There are no specific regulations that dictate how rescues should be performed. Regulatory agencies do require that prompt rescues should be provided, should a fall occur. Research has shown that when a person is suspended by the d-ring of a fall protection harness, serious medical problems will develop after 30 minutes. This suspension time should be reduced if the worker was injured during a fall. The best form on rescue is self-rescue. This form of rescue is possible if the worker has no serious injury, is using proper equipment and has assessed the hazard prior to the fall.

26 26 Rescue Plan Assisted rescue is the next best option for rescuing a fallen worker. This form of rescue will involve other workers using equipment and procedures to raise or lower a person to the ground. Assisted rescue should be pre planned and assigned to a qualified person who is skilled in the use of rescue techniques and equipment. A specific rescue plan must be written and made available before the rescue is performed. Rescue kits to be stored and available at location.

27 27 IMPACT FORCE Weight of worker Free fall distance Lanyard energy absorption (deceleration distance) Depending on how much we weigh, how far we fall, and what slows us down, will determine the impact force.

28 28 Free Fall Distance Stopping Distance Worker Height Margin of Safety (2ft) Total Fall Distance Total Required Clearance FALL HAZARD

29 29 Personal fall arrest systems, when stopping a fall, shall… be rigged such that an employee can neither free fall more than 6 feet (1.8m), nor contact any lower level such as the ground or a working platform FREE FALL DISTANCE


31 31 FALL ARREST SYSTEMS Anchorage Connecting Means Body Support Rescue and/or Escape Plan

32 32 FULL BODY HARNESS The attachment point of the body harness shall be located in the center of the wearers back near shoulder level or above the wearers head.

33 33 Back D-ring * Fall Arrest Front D-ring * Ladders / Escape Hip D-rings * Work Positioning FULL BODY HARNESS Shoulder D-rings * For Confined Space

34 34 1. Lay harness down and untangle. Inspect for damage. 2. Don harness according to style. (step in, vest, etc.) 3. Adjust sub-pelvic strap. 4. Adjust leg straps. 5. Adjust chest support. 6. Adjust dorsal d-ring. Incorrectly adjusted harnesses may cause injury, decrease suspension times or fail in the event of a fall. FULL BODY HARNESS

35 35 SELF- RETRACTING LIFELINE a drum wound line which may be slowly extracted from or retracted onto the drum under tension. after onset of a fall, the device automatically locks the drum and arrests the fall. WARNING: Do not attempt to service a self-retracting lifeline in-house.

36 36 SRL HAZARDS Maintenance required Swing Fall Should be anchored overhead

37 37 LADDER CLIMBING DEVICES Frontal attachment limits fall distance. Short connection (9 or less) reduces impact force to the body so dramatically that injuries due to frontal attachment are negligible. Eliminates the need for ladder cages.

38 38 Check sleeve for function. Connect sleeve to front d-ring of harness using carabiner. Do not add fall distance to the sleeve! LADDER CLIMBING DEVICES

39 39 COVERS Floor openings and gaps must be covered to prevent both people and objects from falling to lower levels. Should be secured, marked and rated to at least twice the potential load.

40 40 DAILY INSPECTION - performed by end user. - prior to use. - not recorded. - looking for anything that affects the condition or function of equipment. - remove questionable equipment.

41 41 FALL PROTECTION STANDARDS Personal fall arrest systems subjected to impact loading shall be immediately removed from service and shall not be used again for employee protection until inspected and determined by a competent person to be undamaged and suitable for reuse

42 42 Personal fall arrest systems shall be inspected prior to each use for wear, damage, and other deterioration, and defective components shall be removed from service FALL PROTECTION STANDARDS Cut Latching - Damage Broken

43 43 1. Wear - regular wear is acceptable, once fibers are being destroyed, retire. 2. Cuts / Tears - retire once they exceed 1/8 inch. 3. Corrosion - once corrosion pits the base metal, retire. FALL PROTECTION STANDARDS

44 44 FALL PROTECTION STANDARDS 4. Ultraviolet Light - a color change will be noticeable, retire once fiber becomes brittle. 5. Paint / Chemicals - obtain MSDS and consult manufacturer. Even mild paints cause fibers to become brittle. 6. Stitch Patterns – take out of service if 2 or more stitch patterns are broken.

45 45 FALL PROTECTION STANDARDS 7. Function - ensure that equipment operates correctly. Gates lock, cam levers move, SRL locks, etc. 8. Heat / Burns - retire webbing when holes are found or areas damaged by heat. Synthetics shrink and when impacted and the shrunken area absorbs most of the impact.

46 46 FALL PROTECTION STANDARDS 9. Impact Indicators - bent grommets, heat signatures on webbing, deformed eyelets, broken d-ring pads, integral impact indicators. Note:All components of a Fall Protection System should be from the same manufacturer to ensure compatibility. Incompatible components can result in roll out where the components can slip out with the potential of releasing the person. Equipment must not be modified.

47 47 CARE OF EQUIPMENT 1. Cleaning - soft goods can be laundered with warm water and mild soap. Hang to dry, do not apply heat. 2. Storage - store in a clean, cool, dark, environment. Lockers, stores, or tool-rooms work well. 3. Marking - ink markers may be used with manufacturers permission. Mark non-load bearing parts. Use name tags if supplied. 4. Life Expectancy - life is determined by condition and function of unit, not time. Follow Manufacturer recommendations on service life for all items.
