Carpentry and joinery involve significant health and safety hazards, from the well-known risks of power tools and machinery to the less obvious but equally serious threat of wood dust. Workshop-based joiners face different hazards than site carpenters, though both must manage risks from cutting equipment, manual handling, and various substances.
This guide covers the essential health and safety requirements for carpenters and joiners working in the UK.
The Legal Framework
Carpentry and joinery work is governed by several key regulations:
Health and Safety at Work etc. Act 1974 - General duties on employers and the self-employed to ensure safety so far as reasonably practicable.
Provision and Use of Work Equipment Regulations 1998 (PUWER) - Requirements for safe equipment, maintenance, guarding, and operator training.
Control of Substances Hazardous to Health Regulations 2002 (COSHH) - Covers wood dust, adhesives, finishes, and preservatives.
Control of Noise at Work Regulations 2005 - Applies given the noise levels from woodworking machinery and power tools.
Control of Vibration at Work Regulations 2005 - Relevant for power tool users.
Work at Height Regulations 2005 - Applies to site carpentry and second-fix work.
Wood Dust - A Serious Health Hazard
Wood dust is one of the most underestimated workplace hazards. It's classified as a carcinogen, causing nasal cancer and other respiratory diseases.
Health Effects
Wood dust exposure can cause:
- Nasal cancer - rare but confirmed link with hardwood dust
- Asthma - occupational asthma from certain wood types
- Respiratory irritation - coughing, sneezing, irritation
- Skin conditions - dermatitis from some species
- Eye irritation - particularly from fine dust
Softwood dust is also hazardous, not just hardwoods.
Workplace Exposure Limits
The Workplace Exposure Limit (WEL) for wood dust is 3 mg/m³ (8-hour time-weighted average) for all wood species.
This limit is often exceeded in poorly controlled environments. HSE takes wood dust seriously and enforcement is increasing.
Control Measures
The hierarchy for dust control:
- Eliminate - Can you reduce cutting, sanding, or machining?
- Engineering controls - Local exhaust ventilation (LEV) on machines, downdraft benches
- Housekeeping - Regular cleaning to prevent dust accumulation
- RPE - Respiratory protection as backup, not primary control
Specific requirements:
| Activity | Primary Control |
|---|---|
| Fixed machinery (saws, planers, sanders) | LEV ducted extraction |
| Portable power tools | On-tool extraction or RPE |
| Hand sanding | RPE and good ventilation |
| Cleaning | H-class vacuum, never dry sweep |
The current workplace exposure limit (WEL) for all wood dust is 3 mg/m³ as an 8-hour time-weighted average. This applies to hardwood, softwood, and MDF. Wood dust is classified as a carcinogen, and exposure must be reduced as low as reasonably practicable.
Local Exhaust Ventilation (LEV)
Workshop machinery should have properly designed and maintained LEV:
- Design - Hoods, ducting, and extraction rates suitable for the machine
- Installation - By competent persons following HSE guidance
- Maintenance - Regular checks, clearing blockages, replacing worn parts
- Testing - Thorough examination and test at least every 14 months
- Records - Keep LEV test reports for 5 years
Respiratory Protection
When LEV isn't sufficient or isn't practicable:
- FFP2 as minimum for wood dust
- FFP3 for hardwood or MDF dust, or prolonged exposure
- Powered respirators for extended work in dusty conditions
- Face-fit testing required for tight-fitting masks
Machinery Safety
Woodworking machinery is inherently dangerous. Circular saws, bandsaws, planers, and routers can cause severe injuries in an instant.
PUWER Requirements
The Provision and Use of Work Equipment Regulations require:
- Equipment suitable for its intended purpose
- Proper maintenance
- Adequate guarding
- Stop and emergency stop controls
- Operator training and information
Guarding
All cutting and dangerous parts must be guarded:
Circular saws:
- Crown guard covering the blade
- Riving knife correctly positioned
- Side guards where needed
- Push sticks for narrow cuts
Bandsaws:
- Blade fully enclosed except at cutting point
- Guard adjusted to workpiece height
- Thrust guides correctly set
Planers/thicknessers:
- Bridge guard on surface planers
- Proper adjustment for workpiece
- No free-running into thicknessers
Routers and spindle moulders:
- Appropriate guards for the cutter
- Jigs and templates for safe workholding
- Never hand-hold small pieces
Inspection and Maintenance
- Daily checks before first use
- Regular maintenance schedule
- Prompt repair of defects
- Records of maintenance and repairs
Operator Training
Anyone using woodworking machinery must be trained and competent:
- Understanding of machine hazards
- Correct setup and adjustment
- Safe operating procedures
- Knowledge of when to stop and seek help
Circular Saw Amputation
A joiner was cutting timber on a table saw. The riving knife had been removed for a previous cut and not replaced. The workpiece kicked back, and his hand was drawn into the unguarded blade.
The joiner lost three fingers. HSE investigation found the riving knife had been removed weeks earlier and the crown guard was damaged. The company was prosecuted for failure to maintain guards.
- •Never remove guards or safety devices
- •Replace any component removed for special operations before normal use
- •Regular inspection catches missing or damaged guards
- •Operator training includes recognising unsafe conditions
Power Tool Safety
Portable power tools are essential for carpentry but present significant hazards.
Common Hazards
- Contact with cutting edges (saws, routers, planers)
- Kickback from circular saws
- Entanglement in rotating parts
- Electric shock from damaged cables
- Flying debris (eye injuries)
- Noise and vibration
Safe Use
Before use:
- Check tool and cable condition
- Ensure guards are in place and working
- Select correct blade/cutter for the material
- Secure the workpiece properly
During use:
- Let the tool reach full speed before cutting
- Don't force the tool - let it cut at its own pace
- Never remove guards or wedge triggers
- Keep hands clear of cutting area
- Use appropriate PPE (eyes, ears, dust protection)
After use:
- Wait for blade/cutter to stop before putting down
- Disconnect before changing blades or adjusting
- Report any defects immediately
110V and Battery Tools
For site work, 110V (from transformer) or battery tools reduce electric shock risk compared to 240V mains tools.
Hand-Arm Vibration
Regular use of vibrating power tools can cause Hand-Arm Vibration Syndrome (HAVS), a painful and disabling condition.
High-Risk Tools
Tools producing significant vibration:
- Sanders (particularly orbital and belt sanders)
- Routers
- Planers
- Jigsaws
- Hammer drills
- Chainsaws
Exposure Limits
| Level | Value | Action Required |
|---|---|---|
| Exposure Action Value | 2.5 m/s² | Action to reduce exposure |
| Exposure Limit Value | 5 m/s² | Must not be exceeded |
Exposure depends on vibration magnitude AND duration. Tool manufacturers provide vibration data.
Controls
- Use lower-vibration tools where available
- Maintain tools properly (sharp blades, balanced)
- Limit exposure duration
- Rotate tasks to share exposure
- Anti-vibration gloves (limited benefit)
- Health surveillance for regular users
Recognising HAVS
Early symptoms include:
- Tingling or numbness in fingers
- Fingers turning white in cold conditions
- Loss of grip strength
- Pain in hands and fingers
Report symptoms early - the condition is progressive but slows if exposure stops.
Noise Exposure
Woodworking is a noisy trade. Uncontrolled exposure leads to permanent hearing damage.
Noise Levels
Common noise sources:
| Activity | Typical Noise Level |
|---|---|
| Circular saws | 95-105 dB(A) |
| Planers | 90-100 dB(A) |
| Routers | 90-100 dB(A) |
| Sanders | 85-95 dB(A) |
| Hammer drills | 95-105 dB(A) |
Daily exposure averaging 85 dB(A) over 8 hours causes hearing damage.
Legal Requirements
| Level | Action |
|---|---|
| 80 dB(A) Lower Action | Provide hearing protection on request, inform of risks |
| 85 dB(A) Upper Action | Hearing protection mandatory, demarcate noisy areas |
| 87 dB(A) Limit | Must not be exceeded (at ear with protection) |
Controls
- Use quieter tools and processes where possible
- Maintain equipment (worn bearings increase noise)
- Separate noisy processes from other work
- Limit time exposed to high noise
- Hearing protection for all noisy work
- Health surveillance (hearing tests) for regular exposure
Chemical Hazards (COSHH)
Carpenters and joiners use various substances requiring COSHH assessment.
Common Substances
| Substance | Hazards | Controls |
|---|---|---|
| Wood preservatives | Toxic, irritant | Gloves, RPE, ventilation, follow SDS |
| Wood stains and dyes | Flammable, irritant | Ventilation, gloves, no ignition sources |
| Varnishes and lacquers | Flammable, vapour inhalation | Ventilation or RPE, no ignition sources |
| Two-pack finishes | Isocyanates (sensitisers) | LEV or RPE, health surveillance |
| Adhesives | Skin sensitisation, vapours | Gloves, ventilation |
| MDF dust | Higher formaldehyde content | Enhanced dust controls |
Requirements
- Obtain Safety Data Sheets for all substances
- Assess risks and identify controls
- Provide appropriate PPE
- Store flammable materials safely
- Health surveillance where needed
Working at Height
Site carpenters frequently work at height for first and second fix operations.
When Regulations Apply
The Work at Height Regulations apply whenever you could fall and be injured:
- Working on scaffolding or platforms
- Using ladders and stepladders
- Installing at ceiling height
- Roof work for fascias and soffits
Controls
Follow the hierarchy:
- Avoid working at height where possible
- Use equipment that prevents falls (platforms, scaffolds)
- Minimise consequences where falls cannot be prevented
Ladder safety:
- Industrial grade (EN 131 Professional)
- Correct angle (75 degrees)
- Secured at top or footed
- Three points of contact
- Don't overreach
Mobile towers:
- Follow manufacturer's instructions
- Level, stable ground
- Proper erection sequence
- Inspect before use
Manual Handling
Carpentry involves significant manual handling - timber, sheet materials, and finished items.
High-Risk Tasks
- Lifting and carrying timber lengths
- Moving sheet materials (plywood, MDF)
- Installing heavy items at height
- Working in confined spaces
- Repetitive handling operations
Controls
Reduce handling:
- Mechanical aids where possible (hoists, trolleys)
- Have materials delivered to point of use
- Use smaller sheet sizes where practical
- Two-person handling for heavy/awkward items
Improve technique:
- Good posture and lifting technique
- Plan lifts before starting
- Clear routes of obstacles
- Don't carry loads up ladders if avoidable
Asbestos Awareness
Carpenters working in existing buildings may encounter asbestos-containing materials.
Where Carpenters Encounter Asbestos
Common locations:
- Ceiling tiles and panels
- Partition board (especially fire-rated)
- Floor tiles and backing
- Insulating board around pipes and in voids
- Textured coatings
- Behind existing fitments being removed
Requirements
Asbestos awareness training is mandatory for anyone whose work could disturb asbestos.
Before work in buildings built or refurbished before 2000:
- Check for asbestos information (registers, surveys)
- Don't disturb suspect materials without confirmation
- If in doubt, get testing done
If You Find Asbestos
- Stop work immediately
- Don't disturb the material further
- Inform the client/building manager
- Assess options - can work proceed without disturbing the asbestos?
Fire Safety
Workshops present specific fire risks from wood dust, shavings, and flammable substances.
Dust and Shavings
Wood dust is a fire and explosion hazard:
- Regular cleaning to prevent accumulation
- Proper extraction and collection systems
- No smoking or naked flames in work areas
- Maintain electrical equipment (sparks can ignite dust)
- Empty dust collection regularly
Flammable Substances
- Store in suitable containers away from ignition sources
- Use in ventilated areas
- Dispose of waste properly (rags with finishes can self-ignite)
- Keep quantities to minimum needed
Workshop Fire Safety
- Suitable extinguishers available and accessible
- Clear escape routes
- Regular inspection of electrical installations
- Hot work controls (welding, heat guns)

Common Questions
Frequently Asked Questions
Site carpenters using portable power tools primarily rely on on-tool extraction and RPE rather than fixed LEV. However, if you do any workshop work with fixed machinery, LEV should be in place. Even for site work, you must control wood dust exposure - this usually means on-tool extraction and proper RPE.
LEV systems for wood dust must be thoroughly examined and tested at least every 14 months. This must be done by a competent person, and records kept for at least 5 years. Between tests, regular checks and maintenance should identify any obvious problems.
Guards should only be removed or adjusted where absolutely necessary for a specific operation, and only if alternative safeguards are in place. Guards must be replaced immediately afterwards. Never leave machines with missing guards available for general use.
FFP2 minimum for general wood dust. FFP3 for hardwood or MDF dust, or for prolonged exposure. Powered respirators are more suitable for extended dusty work. RPE should be face-fit tested for tight-fitting masks. RPE is a backup to engineering controls, not a substitute.
Health surveillance is required for workers with significant regular exposure to: wood dust (respiratory questionnaires and lung function), noise above upper action values (hearing tests), hand-arm vibration (symptom questionnaires). Your risk assessments should identify where surveillance is needed.
Operators must be trained on each specific machine they use. This should cover hazards, safe operating procedures, guards and safety devices, emergency stops, and recognising when to stop and seek help. Records of training should be kept. There's no single mandatory qualification, but competence must be demonstrable.
It's not prohibited, but 110V (via transformer) or battery tools are strongly recommended for site work due to lower electric shock risk. Many sites require 110V or battery tools as a condition of access. 240V tools should have RCD protection if used.
MDF contains formaldehyde which makes the dust more hazardous. Apply enhanced controls: use LEV or on-tool extraction, FFP3 RPE as backup, work outdoors where possible, never dry sweep. The 3 mg/m³ WEL applies, but exposure should be minimised as far as reasonably practicable.
Circular saws are covered by PUWER and general woodworking guidance. Specific requirements include: crown guard covering the blade above the cut, riving knife correctly positioned behind the blade, push sticks for narrow cuts, operator training. HSE guidance provides detailed requirements.
As a rough guide, if you need to shout to be heard 2 metres away, the noise level is likely above 85 dB(A). Formal noise assessment should be done for significant exposure. Signs of problems include temporary hearing changes after work (everything sounds muffled) or ringing in ears (tinnitus).
Summary
Carpentry and joinery involve hazards requiring systematic management. The key requirements include:
- Wood dust control - LEV for machinery, on-tool extraction for power tools, RPE as backup
- Machinery safety - proper guarding, maintenance, and trained operators
- Power tool safety - correct use, maintenance, and PPE
- Noise and vibration - assessment, control measures, health surveillance
- COSHH compliance - assessment of all hazardous substances
- Working at height (site work) - appropriate equipment and training
- Asbestos awareness - mandatory training for work in existing buildings
Professional safety standards protect your health, your employees, and your business reputation.
