OSHA Susan Harwood Training – AGC Fall Protection Susan Harwood Grant Training Program 2013 Wood Frame Construction WRONG BETTER
OSHA Susan Harwood Training – AGC Learning Objectives Understand how OSHA defines residential construction Understand the proper use of guardrails during framing operations Identify best practices during roof truss installation Understand the proper use of personal fall arrest systems (PFAS) during roofing activities
OSHA Susan Harwood Training – AGC Your Rights Under OSHA You have the right to: –A safe and healthful workplace –Know about hazardous chemicals –Information about injuries and illnesses in your workplace –Complain or request hazard correction from employer –Training –Hazard exposure and medical records –File a complaint with OSHA –Participate in an OSHA inspection –Be free from retaliation for exercising safety and health rights 3
OSHA Susan Harwood Training – AGC Employer Responsibilities Provide a workplace free from recognized hazards and comply with OSHA standards Provide training required by OSHA standards Keep records of injuries and illnesses Provide medical exams when required by OSHA standards and provide workers access to their exposure and medical records Not discriminate against workers who exercise their rights under the Act (Section 11(c)) Post OSHA citations and abatement verification notices Provide and pay for PPE 4
OSHA Susan Harwood Training – AGC Complain or Request Corrections Workers may bring up safety and health concerns in the workplace to their employers without fear of discharge or discrimination, as long as the complaint is made in good faith. Workers may file a complaint with OSHA if they believe a violation of a safety or health standard, or an imminent danger situation, exists in the workplace. OSHA regulations protect workers who complain to their employer about unsafe or unhealthful conditions in the workplace. 5
OSHA Susan Harwood Training – AGC Fall Fatalities in Residential Construction FATALITIES TOTAL FALLS FALLS FROM ROOFS Source: BLS CFOI Data
OSHA Susan Harwood Training – AGC OSHA’s Fall Protection Rule and OSHA Instruction STD Compliance Guidance for Residential Construction (b)(13) states … workers “engaged in residential construction activities 6 feet (1.8 m) or more above lower levels shall be protected by guardrail systems, safety net system, or personal fall arrest system.” … or, by alternative fall protection measures allowed under (b) for particular types of work. Addressed further under OSHA’s STD Compliance Guidance for Residential Construction
OSHA Susan Harwood Training – AGC If the employer can demonstrate that it is infeasible or creates a greater hazard to use the required fall protection systems, the employer must instead develop and implement a written site specific fall protection plan in accordance with 29 CFR (k). –OSHA does not consider "economic infeasibility" to be a basis for failing to provide conventional fall protection. There is a presumption that it is feasible and will not create a greater hazard to implement at least one of the fall protection systems. –OSHA expects that the fall protection methods listed in (b)(13) can be used without significant safety or feasibility problems for the vast majority of residential construction activities. Greater Hazard
OSHA Susan Harwood Training – AGC In order to be classified as residential construction, two elements must be met: –The end-use of the structure being built must be as a home, i.e., a dwelling; and –The structure being built must be constructed using traditional wood frame construction materials and methods. The limited use of steel I-beams to help support wood framing does not disqualify a structure from being considered residential construction. Definition of Residential Construction
OSHA Susan Harwood Training – AGC Deck Protection All open edges and holes must be protected Guardrails or other forms of fall protection must be provided Protect the Hole Protect the Edge
OSHA Susan Harwood Training – AGC Guardrail Systems Here we see a floor perimeter completely protected by a guardrail system.
OSHA Susan Harwood Training – AGC Guardrails for Edges These guardrails were set in a way that the walls could be set without removing them.
OSHA Susan Harwood Training – AGC Fall Hazard Stud walls with 24” OC studs for non-load bearing walls must have guardrails. Any opening over 19” wide must be guarded Stud walls on 16” centers are acceptable.
OSHA Susan Harwood Training – AGC Here is a guardrail system still in place that allows installation of dry wall and painting before installing the permanent handrail and removing the guardrail. Other Work Methods
OSHA Susan Harwood Training – AGC Fall Hazards Stairways must have railings before they can be used. Floor holes must be protected immediately as decking is constructed around the hole. Not Good!!
OSHA Susan Harwood Training – AGC Guardrail Systems
OSHA Susan Harwood Training – AGC Guardrail Systems. Brackets and boots are available for guardrail systems that can either be side mounted or deck mounted. Employers should look to the manufacturer’s instructions for proper installation.
OSHA Susan Harwood Training – AGC Window Guard Rails Window openings less than 39” high must be guarded
OSHA Susan Harwood Training – AGC Stay Off Top Plates These workers are standing on the top plates of the walls to install trusses. Workers should instead work from scaffolds or ladders.
OSHA Susan Harwood Training – AGC Fall Hazards All sites have unprotected sides or floor holes at some point during construction. If these sides and holes are not protected, injuries from falls can happen. There’s no reason to work like this …
OSHA Susan Harwood Training – AGC Installing Roof Trusses Workers installing roof trusses from interior bracket scaffolds or ladders.
OSHA Susan Harwood Training – AGC Wall or Bracket Scaffolds Here are examples of a wall bracket or top plate, scaffold systems.
OSHA Susan Harwood Training – AGC These workers are working from bracket/top plate scaffold systems. Guardrails must be able to support 200 pounds in all directions. Other Work Methods
OSHA Susan Harwood Training – AGC Climbing on Trusses Workers installing trusses should not stand on truss cords, especially while the truss is still supported on a crane. Employees should work from ladders or scaffolds or work platforms installed in the trusses.
OSHA Susan Harwood Training – AGC Working on Trusses Workers on trusses must be protected from falling. Fall protection must be established to protect workers The stability of the truss system must be addressed before any fall arrest system is attached.
OSHA Susan Harwood Training – AGC Trusses as Fall Arrest Anchors Single Trusses CANNOT be used as fall arrest anchors unless the anchorage is approved by a qualified person. NOTE: Most single trusses CANNOT support a fall arrest load
OSHA Susan Harwood Training – AGC Truss Collapse Collapses can occur from failure to adequately brace or from an overload. Collapse of the truss system can result in serious injuries or death
OSHA Susan Harwood Training – AGC Alternate Access Use of lifts or scaffolds keeps workers off of areas where the use of fall arrest is difficult. Proper set up is required.
OSHA Susan Harwood Training – AGC Use of Guardrails Engineered guardrail systems allow easy access for sheathing, roofing and utility installation. Multiple trades can be protected by these kinds of systems.
OSHA Susan Harwood Training – AGC Properly assembled and braced IAW the manufacturer’s instruction and the BCSI guide Pre-Assembly of Truss Sections Flying pre-assembled structures into place can minimize worker exposure to fall hazards. Assemble as many parts of the building as possible on the ground. But proper engineering and crane issues must be addressed.
OSHA Susan Harwood Training – AGC Fall Arrest System Anchors For Wood Frame Wood members must be evaluated to assure that can support the forces imposed by fall arrest anchors
OSHA Susan Harwood Training – AGC Anchors An example of a spreader attached to roof trusses. Manufacturer’s requirements must be met. NOTE: –Truss systems and individual members must be evaluated to assure that they can support the forces imposed by fall arrest anchors
OSHA Susan Harwood Training – AGC Guardrails for Roofing Note: The picture on the right lacks protection for the rake edge so some means of protecting this worker (guardrail, safety nets or PFAS) must be used. Guardrails in place during re- roofing activities.
OSHA Susan Harwood Training – AGC Personal Fall Arrest Systems on Roofs PFAS in use during roofing and re-roofing activities.
OSHA Susan Harwood Training – AGC Anchors must be capable of supporting at least 5,000 pounds per employee attached for fall arrest, or must be designed and used : –As part of a complete personal fall arrest system which maintains a safety factor of at least two. –Or under the supervision of a qualified person. Employers should look to the manufacturer’s instructions or the recommendations of a properly qualified person for proper installation. Personal Fall Arrest System Anchor Point This is a 900 lb. Anchor
OSHA Susan Harwood Training – AGC Roof Anchors
OSHA Susan Harwood Training – AGC Permanent Fall Anchorage on Roof Workers can attach a safety rope to the anchors. One worker per anchor. Anchors must be inspected before use. Anchors
OSHA Susan Harwood Training – AGC Roof Fall Restraint Workers are restrained from reaching the edge. If they can reach the edge, full fall arrest must be implemented
OSHA Susan Harwood Training – AGC Use of Retractables Anchorage must be able to support at least 3,000 lbs. Retractables CANNOT be used in a restraint set.
OSHA Susan Harwood Training – AGC Shingle Demolition or Tear-off Fall protection is required during all roof operations Incomplete Fall Protection
OSHA Susan Harwood Training – AGC Wood Frame Fall Anchors These anchor straps are installed during framing and available for use during roofing and siding. NOTE: –Wood members must be evaluated to assure that they can support the forces imposed by fall arrest anchors
OSHA Susan Harwood Training – AGC Ladder Jack Scaffolds Platforms shall not exceed a height of 20 feet. Workers on ladder jacks must use a PFAS. Fall arrest must be tied-off above. Ladders used to support ladder jacks shall be placed, fastened and equipped with devices to prevent slipping.
OSHA Susan Harwood Training – AGC Pump-jack Scaffolds Pump jacks are safer than ladder jacks. There are fall issues when anchoring pump jack poles.
