Hazard
Falls from Height
Carpenters frequently work at elevated heights during framing, cladding installation, and decking construction. Falls from scaffolding, ladders, roof structures, and unguarded floor edges represent the leading cause of fatalities in carpentry work. Risk factors include inadequate edge protection, improper scaffold erection, unsafe ladder use, and working on wet or cluttered surfaces. Even falls from relatively low heights can result in serious injuries when workers land on materials, equipment, or uneven ground. Control measures must include installation of temporary edge protection systems complying with AS/NZS 4994, proper scaffold design and inspection, use of appropriate access equipment, and when required, correctly fitted fall arrest systems with designated anchor points.
Hazard
Manual Handling Injuries
Carpentry work involves frequent lifting, carrying, and positioning of heavy and awkward materials including timber framing members, sheet materials, cabinetry, and steel components. Manual handling tasks often occur in confined spaces, at height, or in awkward postures, increasing injury risk. Lower back injuries, shoulder strains, and soft tissue damage are common consequences of poor manual handling practices. Risks are elevated when working with long members such as wall frames and roof trusses that require coordination between multiple workers. Control measures include mechanical lifting aids where practicable, team lifting protocols, pre-planning material placement to minimise handling, breaking down loads into smaller components, and training workers in correct manual handling techniques specific to carpentry materials.
Hazard
Power Tool Contact and Entanglement
Carpenters use various power tools including circular saws, nail guns, drills, routers, and planers which present risks of lacerations, puncture wounds, and entanglement injuries. Kickback from circular saws, misfired nails from pneumatic nailers, and contact with rotating drill bits or router cutters can cause severe injuries. Risk factors include inadequate guarding, working in awkward positions, fatigue, distraction, and improper tool selection for the task. Specific concerns include double-fire nail gun incidents, blade binding in circular saws when cutting treated timber or sheet materials, and entanglement of loose clothing or gloves in rotating equipment. Control measures must address tool selection, maintenance and inspection, guarding verification, appropriate PPE including cut-resistant gloves where suitable, training in correct tool operation, and sequential safety mechanisms on nail guns.
Hazard
Silica Dust and Wood Dust Exposure
Cutting, routing, and sanding operations generate hazardous airborne dusts including crystalline silica from fibre cement products and respirable wood dust from timber materials. Chronic exposure to crystalline silica causes silicosis, an irreversible lung disease, while wood dust is classified as a carcinogen and can cause respiratory sensitisation and nasal cancer. Australian workplaces must comply with workplace exposure standards of 0.05 mg/m³ for respirable crystalline silica. Risks are heightened in enclosed work areas with poor ventilation, during dry cutting of fibre cement sheets, and when sanding hardwood timbers. Control measures include eliminating dry cutting where possible through use of water suppression or pre-scored products, on-tool dust extraction systems, local exhaust ventilation, respiratory protective equipment rated for the specific dust hazard, and atmospheric monitoring to verify control effectiveness.
Hazard
Struck by Falling Objects
Multi-level carpentry work creates overhead hazards from falling tools, materials, and off-cuts. Materials being lifted to upper levels, components being installed overhead, and inadequately secured tools or materials on work platforms present striking hazards to workers below. Incidents often result in head injuries, even when helmets are worn, particularly from heavier items such as framing timber or steel components. Risk factors include congested work areas, poor housekeeping, inadequate storage on work platforms, working beneath active installation work, and failure to establish exclusion zones. Control measures include physical barriers and exclusion zones beneath overhead work, toolbox tethering systems, material restraint on platforms, toe boards on scaffolding, and debris netting on multi-storey construction to contain falling materials.
Hazard
Awkward Postures and Repetitive Movements
Carpentry work frequently requires sustained awkward postures including overhead work during ceiling installation, kneeling during floor laying, and working in confined spaces. These ergonomic hazards lead to musculoskeletal disorders including shoulder impingement, tennis elbow, knee damage, and chronic back pain. Risk factors increase with work duration, lack of task variation, and inadequate rest breaks. Control measures include task rotation to vary muscle group loading, use of ergonomic tools with anti-vibration features, mechanical assistance for overhead work such as panel lifters, positioning work at appropriate heights, and scheduled rest breaks.
Hazard
Electrical Hazards
Carpenters work near electrical installations and use electrical power tools, creating risks of electric shock and electrocution. Specific hazards include cutting into concealed wiring, damaged extension leads, and working near overhead power lines. Contact with energised conductors can cause fatal shock, burns, and secondary injuries from falls. Control measures include electrical location services before cutting or drilling, mandatory RCD protection rated at 30mA for portable equipment, pre-start inspection of electrical equipment, maintaining clearances from power lines, and ensuring only licensed electricians perform electrical work.
Hazard
Hazardous Substance Exposure
Carpentry involves exposure to hazardous substances including timber treatment chemicals, adhesives containing volatile organic compounds, and preservatives. Skin contact with treated timbers can cause dermatitis. Vapours from adhesives can cause respiratory irritation in poorly ventilated spaces. Cutting treated timber releases toxic fumes. Control measures include identifying treated timbers, using appropriate PPE including gloves and respiratory protection, ensuring adequate ventilation when using adhesives, never burning treated timber off-cuts, and proper waste disposal.
