Power Tools & General Equipment SWMS
Operation of common power tools including angle grinders, drills, saws, and pneumatic equipment.
SWMS variants reference your state's WHS legislation. Instant download after payment.
This SWMS covers the operation of power tools and general portable equipment used across construction, workshop, and maintenance trades โ angle grinders, circular saws, drop saws, reciprocating saws, drills (rotary and hammer), nail guns (pneumatic and gas-powered), impact drivers, router, planer, belt sanders, and pneumatic equipment (impact wrenches, jack hammers). It is written for tradespeople using powered hand tools as a routine part of their work, for apprentices under direct supervision, for maintenance personnel operating workshop equipment, and for self-employed operators as a standalone document or companion to a trade-specific SWMS.
Power tools are not a specific HRCW category in themselves. Individual tool use becomes HRCW under Category 13 only when the work is construction work as defined in Part 6.4. In workshop and maintenance contexts this SWMS operates under the general plant provisions of Part 4.5 (r. 203-216) of the WHS Regulation 2025 (NSW) and is authored without an HRCW breakdown. However, power tool injuries dominate the trade injury statistics: angle grinder kickback is the single most common mechanism for severe hand and facial injuries in Australian construction; nail gun recoil and unintended discharge account for a large share of penetrating injuries; and noise and vibration exposure from sustained tool use are cumulative-disease drivers. This document is CIH-authored against the current regulatory baseline.
Hazards identified
11 hazards covered, sorted by priority.
Severe laceration and penetrating injury to face, neck, torso, and hands from kickback; fatal arterial injury where the cutting disc strikes neck or femoral region; disc disintegration projects shards at high velocity.
Blade-in-hand injury on kickback; severe laceration of hands and forearms; eye injury from ejected debris.
Penetrating injury from nails driven into torso, head, or bystander; hand-through-material injuries common from incorrect tip-contact sequence.
Hand or clothing caught in rotating bit or belt; degloving and crushing injuries; serious hand and forearm injuries.
Permanent noise-induced hearing loss; peak levels on impact tools regularly exceed 110 dB(C) peak โ above the 140 dB(C) ceiling limit for certain tools.
Hand-arm vibration syndrome (HAVS) and carpal tunnel syndrome; reversible in early stages but permanent if exposure is not managed; exposure above the ISO 5349 action value is common.
Corneal abrasion, penetrating eye injury, and chemical eye exposure; eye injuries account for a significant share of tool-related lost-time injury.
Electrocution from power tool lead faults; construction site electrical failures account for a leading cause of serious electrical incidents.
Silicosis and lung cancer at cumulative exposure above the 0.05 mg/m3 (8-hour TWA) workplace exposure standard.
Respiratory irritation, occupational asthma, and IARC Group 1 carcinogen exposure for wood dust; welding fume-like exposures for grinding on coated metals.
Thermal burns to hands and forearms; spark ignition of combustibles during grinding or cutting operations.
Control measures

Worked example
A commercial refurbishment contractor employs 14 tradespeople (carpenters, labourers, apprentices) working across multiple small commercial fit-out jobs in inner Sydney. Before implementing this SWMS, each trade had its own SWMS but no consolidated tool-use document. This SWMS is rolled out as the baseline for power tool operation across the business. Key changes: angle grinder training session for all workers (three workers had been using wood-cutting discs on grinders โ practice stopped); silica control protocol for brick cutting (M-Class vacuum added to all utes for on-site cutting); test-and-tag programme reviewed and centralised with quarterly testing schedule; vibration exposure survey planned for the three carpenters with daily rotary-hammer use. SWMS reviewed quarterly with incident and near-miss data feeding back into controls. First quarter review flagged a near-miss where an apprentice used a grinder without a side handle โ sign-off protocol updated.

Frequently asked questions
Are gloves required or prohibited during power tool use?
Depends on the tool. Cut-resistant gloves are essential for handling sharp materials before and after cutting, and for holding workpieces where a slip could cause hand injury. However, gloves are an entanglement hazard on some rotating tools โ drill presses, lathes, routers, and belt sanders. The general rule: gloves ON for handling, gloves OFF for operating rotating tools where entanglement is possible. Check the manufacturer's manual for the specific tool.
What's the biggest cause of serious angle grinder injuries?
Kickback. The cutting disc binds in the material and the grinder rotates violently towards the operator, often into the face or neck. Prevention is a combination of correct disc for material, not over-forcing the cut, two-handed grip with side handle, body position out of the kickback line, and sharp disc maintained. Angle grinders remain one of the most lethal tools on construction sites despite being routinely used.
Are pneumatic nail guns safer than gas or battery-powered nail guns?
All nail gun types have similar injury profiles when misused. Pneumatic guns have been subject to most safety research and improvement over time. The key control is the trigger mechanism: sequential trip (must release and re-press trigger for each nail) is significantly safer than contact trip (hold trigger, bounce tip to fire). For overhead and finishing work, sequential trip is preferred by SafeWork Australia guidance. For framing work, contact trip is often used for productivity but with heightened awareness.
Do I need to test-and-tag my own tools?
Test-and-tag is mandatory under AS/NZS 3012 for power tools on construction and demolition sites. The frequency is three months for construction sites. In a workshop or office environment, the frequency is longer per AS/NZS 3760 (generally 12 months). A competent person โ not necessarily a licensed electrician, but someone trained on the test equipment and method โ performs the testing. Self-employed tradespeople can test their own tools if competent; many contract test-and-tag to a service provider.
Can I use a wood-cutting disc on an angle grinder for a timber cut?
Only if the disc is specifically rated for angle grinder use AND the grinder has a fitted wood-cutting guard. Most 'wood cutting discs' sold for angle grinders are marketed for carving and shaping operations, not straight cuts. They have specific operational parameters. Cutting timber with a general-purpose grinder and metal-cutting disc is extremely dangerous โ the disc can catch and cause severe kickback. Use a circular saw, jigsaw, or reciprocating saw for wood cutting.
What RCD protection is required for power tools on a construction site?
AS/NZS 3012:2019 requires 30 mA RCD protection on all circuits serving power tools on construction and demolition sites. The RCD can be at the distribution board, at a portable RCD plugged into an outlet, or built into a tool's inline cord. A licensed electrician installs the builder's temporary supply with the RCD protection and inspects it per the Standard. Workers verify the RCD is functional at the start of each shift by pressing the test button.
