Task – Cut the material
Entanglement from contact with blade
- Deep cuts or amputation
- Potential piercing injury
- FIX guarding.
- POSITION the moving blade as far possible below the surface of the material being cut.
- HOLD blades in the cut until the blade stops moving, to avoid the blade breaking when it hits the material.
- Material MUST be held securely. Holding it by hand or by leaning on it with a knee or foot is NOT enough.
Material can become unstable during cutting, leading to loss of control. Withdrawing a moving blade during a cut can allow the blade to impact the material and break.
- Vibration may injure fingers, hands, or arms
- WEAR anti-vibration gloves to protect hands from excessive vibration.
- LIMIT usage time and take rest periods.
- KEEP the workpiece stationary and clamped.
￼￼The oscillating action may cause injury through exposure to vibration, especially if used for long periods.
Task – Cut the material
- KEEP coins, hand tools, screws, and similar objects away from power tool battery terminals.
- ENSURE battery caps are fitted during transport.
- CONNECT mains powered saws through an RCD to protect against electric shock.
- ENSURE saws, extension leads, and RCDs are tested regularly.
Power tool battery terminals touching metal objects can cause a fire hazard. Power tool batteries are extra low voltage (18 V is common) but designed to supply high amounts of electric current. Mains powered jig saws are a portable appliance with potential to give electric shocks if faults develop.
Other (non-mechanical) hazards
- Avoid touching the blade with fingers until it cools.
Blades heat up as they cut. When removing a blade after cutting, it may be hot enough to burn.
- REDUCE noise levels by isolating machines or enclosing within noise barriers.
- ASSESS noise levels.
- ARRANGE hearing screenings.
- ALWAYS WEAR hearing protection.
A safe noise level over an eight hour day is 85dB(A). A jig saw may exceed this noise intensity, particularly if it is used to cut sheet metal.
- Eye irritation or damage
- Breathing problems, lung damage or cancer
- Worsening of existing health problems
- CONNECT dust extraction to the exhaust on the saw if possible.
- ALWAYS WEAR eye protection.
- ALWAYS USE respiratory protection.
Slips trips and falls
- KEEP up-to-date housekeeping procedures.
- KEEP the area around machines clear of slip and trip hazards.
Task – Maintenance, cleaning & repairs
Contact, impact or entanglement from unexpected movement
- Contact or impact injuries
- Cuts or piercing injuries
- UNPLUG power or REMOVE batteries during blade changes, maintenance, cleaning and repairs.
- When changing a blade with a hand tool, the hand tool MUST be removed before power is restored to the saw.
Saw movement can start accidentally during blade changes.
