General Construction Activities Job Safety Analysis (JSA)

Job / Task

General construction activities, including site preparation, material handling, use of hand and power tools, equipment operation, access and egress, elevated work, housekeeping, and routine construction tasks.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies common hazards associated with general construction activities and establishes safe work practices and controls to prevent struck-by, caught-between, fall, electrical, material-handling, tool-related, and other construction injuries.

Personnel Qualifications

Employees shall be trained for the work they are assigned and shall understand the hazards, equipment, tools, and controls applicable to their tasks.

Employees shall:

• Perform only work for which they are trained, qualified, and authorized.
• Understand the planned work and participate in the pre-task JSA/JHA review.
• Inspect tools, equipment, PPE, and the work area before use or beginning work.
• Follow manufacturer instructions, applicable procedures, permits, and site requirements.
• Use required PPE and protective systems.
• Maintain awareness of other trades, vehicles, equipment, overhead work, and changing conditions.
• Stop work when an unsafe or unanticipated condition is identified.
• Report hazards, damaged equipment, incidents, and near misses to supervision.

Required PPE

PPE shall be selected based on the task, equipment, materials, and work environment and may include:

• Safety glasses with side protection.
• Safety footwear with appropriate toe protection and slip-resistant soles.
• Hard hat where head or overhead hazards exist.
• Work gloves appropriate for the task.
• High-visibility apparel where vehicles, mobile equipment, or traffic are present.
• Hearing protection where noise exposure requires it.
• Face protection for grinding, cutting, chipping, or other flying-particle hazards.
• Fall protection where required.
• Respiratory protection when required by the hazard assessment and Respiratory Protection Program.
• Additional task-specific PPE required by the work activity or site.

PPE does not replace engineering controls, safe work practices, guarding, barricades, or other required protective measures.

JSA – Job Steps, Hazards, and Controls

Step 1 – Plan the Work

Potential Hazards

• Provide adequate lighting.
• Reassess the area when conditions change.

Step 3 – Inspect Tools and Equipment

Potential Hazards

• Damaged or defective tools.
• Missing guards or safety devices.

• Verify guards, handles, cords, plugs, controls, and safety devices are in place and functional.
• Use tools only for their intended purpose and within manufacturer limitations.
• Remove defective equipment from service.
• Do not bypass or defeat guards or safety devices.

Step 4 – Handle and Store Materials

Potential Hazards

• Strains and sprains.
• Crushing or caught-between injuries.
• Falling or shifting materials.
• Cuts and punctures.
• Unstable stacks.

Required Controls

• Evaluate the load before lifting or moving it.
• Use mechanical assistance or team lifting when materials cannot be safely handled by one employee.
• Keep hands and body parts away from pinch points.
• Stack, block, interlock, or secure materials to prevent sliding, collapse, or displacement.
• Keep storage areas and access routes orderly.

Step 5 – Use Hand and Power Tools

Potential Hazards

• Cuts and lacerations.
• Flying particles.
• Entanglement.
• Noise.
• Electrical shock.
• Kickback or loss of control.

Required Controls

• Use the correct tool for the task.
• Maintain required guards and safety devices.
• Secure workpieces when necessary.
• Keep hands clear of cutting and moving parts.
• Disconnect or de-energize equipment before adjustments or accessory changes when required.
• Use required eye, face, hearing, and other task-specific protection.

Step 6 – Work Around Vehicles and Mobile Equipment

Potential Hazards

• Struck-by incidents.
• Backing hazards.
• Blind spots.
• Caught-between or crushing hazards.
• Equipment rollover.

Required Controls

• Only trained and authorized employees may operate powered equipment.
• Conduct required pre-use inspections.
• Wear seat belts where provided.
• Maintain separation between pedestrians and operating equipment.
• Stay out of blind spots and never position yourself between moving equipment and fixed objects.
• Use spotters when required or when the operator cannot safely see the work area.

Step 7 – Perform Elevated Work

Potential Hazards

• Falls to a lower level.
• Falling objects.
• Unstable ladders, scaffolds, or platforms.
• Improper access.

Required Controls

• Use ladders, scaffolds, aerial lifts, and work platforms appropriate for the task.
• Inspect access equipment before use.
• Maintain guardrails or use personal fall protection when required.
• Keep elevated work areas orderly.
• Control tools and materials where falling-object hazards exist.
• Do not use makeshift platforms or unauthorized access methods.

Step 8 – Work Near Electrical Hazards and Utilities

Potential Hazards

• Electric shock or electrocution.
• Arc hazards.
• Contact with overhead power lines.
• Underground utility strikes.
