Work Near Open Edges Job Safety Analysis (JSA)

Job / Task

Construction, maintenance, installation, inspection, repair, material handling, or other work performed near unprotected sides, leading edges, elevated platforms, floor perimeters, mezzanines, roofs, excavations, or similar locations where an employee could fall to a lower level.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies hazards associated with work near open or unprotected edges and establishes controls to prevent falls, falling-object incidents, trips near edges, improper use of fall-protection systems, and injuries during access, work, and emergency response.

Personnel Qualifications

Employees exposed to open-edge fall hazards shall be trained to recognize fall hazards and properly use the fall-prevention and fall-protection systems required for the task. Employees using personal fall arrest or restraint systems shall understand inspection, proper fit, anchorage, connection methods, fall clearance, swing-fall hazards, and rescue procedures.

Employees shall:

• Identify open edges and fall exposures before beginning work.
• Use required guardrails, personal fall arrest systems, restraint systems, safety nets, or other approved fall-protection methods.
• Inspect fall-protection equipment before each use.
• Use only approved anchorages and compatible components.
• Maintain required fall protection while approaching, working near, or moving along open edges.
• Keep access routes and work areas near edges free of trip hazards.
• Control tools and materials that could fall from elevated surfaces.
• Avoid working backward toward an unprotected edge.
• Immediately report missing guardrails, damaged equipment, unsafe anchorages, or changed site conditions.
• Stop work when required fall protection, safe access, anchorage, or rescue provisions are inadequate.

Required PPE

PPE shall be selected based on the task, elevation, and surrounding hazards and may include:

• Hard hat.
• Safety glasses with side protection.
• Work gloves appropriate to the task.
• Slip-resistant safety footwear.
• High-visibility apparel where traffic or mobile-equipment exposure exists.
• Full-body harness and compatible lanyard, self-retracting lifeline, lifeline, or restraint device where required.
• Hearing protection where noise exposure requires it.
• Additional task-specific PPE identified by the hazard assessment.

JSA – Job Steps, Hazards, and Controls

Step 1 – Evaluate the Work Area

Potential Hazards

• Fall from an open edge.
• Unrecognized change in elevation.
• Falling objects.

Required Controls

• Identify all unprotected sides, leading edges, floor perimeters, platforms, openings, and changes in elevation.
• Determine the distance to the lower level and identify obstructions below.
• Evaluate the work surface for strength, stability, slope, and condition.
• Identify personnel, equipment, or occupied areas below the work.
• Select required fall prevention and fall protection before work begins.

Step 2 – Establish the Fall-Hazard Area

Potential Hazards

• Unprotected employee access.
• Unexpected approach to edge.

Required Controls

• Clearly identify the area where open-edge fall hazards exist.
• Use guardrails, barricades, warning systems, controlled access, or other measures as applicable.
• Restrict unnecessary personnel from the hazard area.
• Coordinate with other trades whose work may affect edge protection.
• Maintain adequate lighting so edges and protective systems remain visible.

Step 3 – Inspect Walking and Working Surfaces

Potential Hazards

• Slip or trip near edge.
• Surface failure.

Required Controls

• Verify surfaces can support employees, tools, equipment, and materials.
• Remove loose debris, cords, hoses, packaging, and other trip hazards.
• Correct wet, icy, oily, uneven, or unstable surfaces before work.
• Identify fragile or deteriorated surfaces and prevent access until evaluated.
• Maintain clear travel paths away from exposed edges where practical.

Step 4 – Inspect Guardrail Systems

Potential Hazards

• Fall due to missing or damaged guardrail.
• Guardrail failure.

Required Controls

• Inspect toprails, midrails, posts, toe boards, connections, and supporting components.
• Verify guardrails are complete, secure, and properly positioned.
• Do not lean materials, equipment, or heavy loads against guardrails.
• Do not use guardrails as anchorage points unless specifically designed and approved for that purpose.
• Report and correct damaged or missing guardrails before exposure continues.

Step 5 – Control Temporary Guardrail Removal

Potential Hazards

• Immediate fall exposure.
• Unprotected opening in edge protection.

Required Controls

• Do not remove guardrails unless necessary for the work and authorized.
• Establish alternate fall protection before removing any guardrail section.

Training

Employees exposed to open-edge fall hazards shall receive training by a competent or qualified person, as applicable, so they can recognize fall hazards and understand the procedures necessary to minimize those hazards. Training shall address unprotected sides and edges, leading edges, guardrail systems, personal fall arrest and restraint systems, equipment inspection, anchorage, fall clearance, swing-fall hazards, continuous protection, falling-object prevention, changing site conditions, and rescue procedures.
