• Pinch points
• Flying material
• Other moving parts

Employees should not operate equipment when required guards are missing, damaged, improperly adjusted, or ineffective.

Lockout/Tagout and Equipment Servicing

Employees performing maintenance, repair, blade changes, jam clearing, or other servicing activities should protect themselves from unexpected equipment startup and hazardous energy.

Equipment should be shut down and disconnected or isolated from its energy source before servicing when required.

Fixed equipment should have appropriate means for disconnecting and controlling energy.

Employees authorized to perform lockout/tagout should receive appropriate training.

Fall Protection

Carpenters frequently work near unprotected edges, floor openings, wall openings, roofs, stairways, balconies, elevated decks, scaffolds, and other fall hazards.

Fall hazards should be evaluated before work begins.

Depending on the operation, fall protection may include:

• Guardrail systems
• Personal fall arrest systems
• Covers
• Safety nets
• Scaffold fall protection
• Properly constructed stairways
• Safe ladder access
• Other permitted fall-protection systems

Employees should be trained to recognize fall hazards and properly use the fall-protection systems provided.

Floor and Wall Openings

Carpenters may create, work around, or temporarily expose floor and wall openings during construction.

Openings should be protected as required using appropriate covers, guardrails, or other protective systems.

Covers should be capable of supporting anticipated loads and should be secured when necessary to prevent displacement.

Employees should not remove opening protection unless authorized and necessary for the work.

Protection should be restored promptly when the work is complete.

Ladder and Stairway Safety

Ladders are commonly used for carpentry installation, access, measuring, fastening, trim work, and other short-duration tasks.

Employees should:

• Inspect ladders before use.
• Select the proper ladder for the task.
• Place ladders on stable surfaces.
• Maintain three points of contact while climbing.
• Face the ladder while climbing.
• Avoid overreaching.
• Keep ladders away from electrical hazards.
• Follow manufacturer load ratings.
• Never use damaged ladders.
• Avoid standing on prohibited steps or the top of a stepladder.

Tools and materials should be handled in a manner that allows safe climbing.

Scaffolding Safety

Carpenters may work from supported scaffolds, mobile scaffolds, pump-jack scaffolds, or other scaffold systems.

Scaffolds should be:

• Properly erected and supported.
• Inspected before use.
• Provided with safe access.
• Protected against overloading.
• Equipped with required fall protection.
• Maintained free of unnecessary debris and trip hazards.

Employees should not climb scaffold cross braces or use makeshift devices to gain additional height.

Aerial Lifts and Scissor Lifts

Boom lifts and scissor lifts may be used for exterior carpentry, framing, siding, trim, soffit, fascia, window installation, and other elevated work.

Only trained and authorized employees should operate aerial lifts.

Employees should follow manufacturer requirements concerning:

• Pre-use inspections
• Platform capacity
• Fall protection
• Ground conditions
• Travel
• Positioning
• Overhead hazards
• Electrical clearances

Employees should never stand or climb on platform guardrails to obtain additional height.

Personal Protective Equipment

PPE should be selected based on the hazards associated with each carpentry task.

Common PPE may include:

• Safety glasses
• Goggles
• Face shields
• Hard hats
• Work gloves
• Hearing protection
• Safety-toe footwear
• High-visibility apparel
• Respiratory protection
• Fall protection equipment

Employees should inspect PPE before use and replace damaged or defective equipment.

Eye protection is particularly important when employees operate saws, nail guns, drills, routers, grinders, and other equipment capable of producing flying particles.

Hearing Conservation

Circular saws, miter saws, table saws, routers, planers, nail guns, compressors, and other carpentry equipment may produce hazardous noise.

The company should evaluate employee noise exposures and implement hearing conservation requirements when applicable.

Controls may include:

• Selecting quieter equipment.
• Maintaining tools and machinery.
• Increasing distance from noise sources.
• Limiting exposure duration.
• Providing appropriate hearing protection.

Employees should be trained in the proper use and care of hearing protection when required.

Cutting, sanding, routing, drilling, and machining wood can generate airborne wood dust.

Dust exposure should be minimized using appropriate controls such as:

• Local exhaust ventilation
• Tool-connected dust collection
• Vacuum systems
• Appropriate work practices
• Good housekeeping
• Respiratory protection when required

Dust accumulation should also be controlled because excessive combustible dust and wood waste can contribute to fire hazards.

Silica Exposure

Although silica exposure is not typically the primary hazard associated with carpentry, carpenters may drill, cut, grind, or fasten materials containing concrete, masonry, brick, mortar, stone, fiber-cement products, or other silica-containing materials.

The contractor should evaluate these tasks to determine whether silica exposure controls are required.

When applicable, controls may include:

• Water-delivery systems
• Dust collection
• HEPA-filtered vacuums
• Appropriate work practices
• Respiratory protection
• A written Silica Exposure Control Plan

Employees should not dry sweep silica-containing dust when prohibited and feasible alternatives are available.

Electrical Safety

Carpenters frequently use portable electrical tools, extension cords, temporary power systems, generators, and battery chargers.

Employees should inspect electrical tools and cords before use.

Damaged cords, plugs, receptacles, or tools should be removed from service.

Electrical cords should be protected from:

• Sharp edges
• Vehicle traffic
• Water
• Pinching
• Crushing
• Cutting
• Other physical damage

Ground-fault circuit interrupter protection should be provided as required.

Temporary Electrical Systems

Construction sites frequently rely on temporary electrical installations.

Employees should avoid unauthorized modifications to temporary wiring and should not use damaged receptacles, cords, panels, or electrical equipment.

Electrical panels and disconnects should remain accessible.

Employees should maintain required clearance from energized electrical equipment and report unsafe electrical conditions.

Overhead Power Lines

Carpenters performing framing, roof work, exterior installation, scaffold work, material handling, or aerial-lift operations may work near overhead electrical lines.

Before work begins, employees should identify overhead power lines and maintain required clearances.

Long materials such as lumber, ladders, siding, metal trim, and scaffold components should be handled carefully near electrical lines.

Manual Lifting and Material Handling

Carpenters routinely handle:

• Lumber
• Plywood
• Doors
• Windows
• Cabinets
• Countertops
• Trim
• Hardware
• Tools
• Equipment
• Sheet materials

Employees should evaluate loads before lifting and use mechanical assistance or team lifting when appropriate.

Special care should be taken when carrying large sheet materials because they can obstruct vision and be difficult to control in windy conditions.

Materials should be stored securely to prevent shifting, falling, or creating trip hazards.

Forklifts and Material Handling Equipment

Forklifts, telehandlers, pallet jacks, and other material-handling equipment may be used to move lumber, sheet goods, trusses, doors, windows, and other materials.

Only trained and authorized employees should operate powered industrial trucks or other equipment requiring operator training.

Loads should be stable and within equipment capacity.

Employees should remain clear of elevated forks and suspended or unstable loads.

Housekeeping

Good housekeeping is especially important in carpentry because scrap lumber, sawdust, nails, fasteners, cords, packaging, and cutoffs can quickly create hazards.

Work areas should be kept free of unnecessary:

• Scrap lumber
• Protruding nails
• Sawdust
• Packaging
• Cords and hoses
• Tools
• Fasteners
• Other debris

Protruding nails should be removed or bent over when appropriate.

Walkways, stairs, ladders, scaffolds, exits, and work platforms should remain clear.

Fire Prevention

Wood, sawdust, adhesives, finishes, solvents, fuels, and other combustible materials can create fire hazards.

Employees should:

• Control ignition sources.
• Store flammable materials properly.
• Maintain good housekeeping.
• Keep exits accessible.
• Observe smoking restrictions.
• Know the location of fire extinguishers.
• Follow hot-work procedures when applicable.

Combustible waste should not be allowed to accumulate unnecessarily.

Hazard Communication

Carpenters may use adhesives, sealants, coatings, stains, finishes, solvents, treated lumber products, cleaning chemicals, and other hazardous materials.

The Hazard Communication Program should address:

• Chemical inventory
• Container labeling
• Safety Data Sheets
• Employee training
• Chemical storage
• Non-routine tasks
• Protective measures

Employees should understand the hazards associated with the products they use.

Remodeling and Renovation Hazards

Carpentry contractors performing remodeling or renovation may encounter hazards not normally present during new construction.

These may include:

• Lead-containing coatings
• Asbestos-containing materials
• Mold or water damage
• Hidden electrical wiring
• Hidden plumbing or utilities
• Structural instability
• Occupied work areas
• Dust and debris
• Unknown chemicals or materials

Potential hazardous materials should be evaluated before employees disturb suspect materials.

Work in occupied buildings should be planned to protect employees, occupants, and the public.

Working Around the Public

Carpenters may perform remodeling, repair, installation, and finish work in occupied homes, offices, retail locations, schools, healthcare facilities, and other occupied properties.

Work areas should be controlled to prevent unauthorized persons from entering hazardous areas.

Controls may include:

• Barricades
• Signs
• Temporary partitions
• Controlled access
• Tool and material storage
• Dust containment
• Maintaining clear exits and walkways

Tools, fasteners, sharp objects, and chemicals should not be left where occupants or children can access them.

Job Safety Analysis

A Job Safety Analysis (JSA) can help carpentry contractors identify hazards and controls before work begins.

JSAs may be appropriate for:

• Circular saw operation
• Table saw operation
• Miter saw operation
• Nail gun use
• Framing
• Roof framing
• Floor and wall openings
• Scaffold work
• Ladder work
• Aerial lift work
• Door installation
• Window installation
• Cabinet installation
• Material handling
• Remodeling and demolition
• Work near overhead power lines
• Cutting or drilling concrete and masonry

The JSA should identify the steps of the task, associated hazards, and controls needed to perform the work safely.

Carpentry Safety Training

Employees should receive training appropriate to their assigned work and exposures.

Training may include:

• Hand and power tools
• Circular saws
• Table and miter saws
• Nail guns
• Woodworking equipment
• Machine guarding
• Fall protection
• Ladders
• Scaffolds
• Aerial lifts
• PPE
• Electrical safety
• Material handling
• Hearing conservation
• Wood dust
• Silica exposure
• Hazard communication
• Emergency procedures

Training should be documented and updated when equipment, work practices, hazards, or regulatory requirements change.

Building a Carpentry Contractor Safety Manual

A Carpentry Contractor Safety Manual should be customized to the contractor’s actual operations rather than relying on a generic construction safety manual.

A finish carpentry contractor installing cabinets, doors, trim, and millwork may require a different combination of programs than a rough carpentry contractor performing structural framing, roof framing, decking, or exterior construction.

Similarly, a remodeling contractor working inside occupied buildings may face hazards involving lead, asbestos, dust control, public protection, and existing electrical systems that are less common during new construction.

The completed safety manual should address the hazards employees actually encounter and provide practical procedures supervisors and employees can use in the field.

When properly developed, the safety manual supports OSHA compliance, employee training, hazard assessments, JSAs, inspections, incident investigations, project safety requirements, and the contractor’s overall safety-management system.
