Hand tools

Inspect handles for cracks, splinters or looseness.
Check striking faces for mushrooming or chips.
Dress mushroomed edges flat with a file or grinder to prevent dangerous metal shards from flying off.
Verify cutting edges are sharp and undamaged.
Confirm jaws, pivots and adjustments work smoothly.
Check that tools are clean and free of grease or oil.
Confirm the right tool is used for the task, not improvised.

Power tool body

Inspect the housing for cracks, melting or impact damage.
Check switches and triggers operate and do not stick.
Ensure the tool shuts off immediately when released; sticking triggers can cause severe loss of control.
Verify bits, blades and accessories are sharp and secure.
Confirm air vents are clear of dust and debris.
Clogged motor vents cause rapid overheating, insulation breakdown, and premature tool motor failure.
Check for unusual noise, vibration or burning smell on test.
Verify the data plate and ratings are legible.

Cords and plugs

Inspect the cord for cuts, fraying or exposed wires.
Tools with damaged cords must be removed from service, not taped over.
Check the plug for bent, missing or damaged pins.
Verify the grounding pin is intact on grounded tools.
Never use a 3-prong plug with a missing or clipped ground pin, as it removes critical shock protection.
Confirm strain reliefs at the plug and tool are secure.
Check extension cords are rated and undamaged.
Verify cords are kept clear of water, heat and traffic.

Guards and safety devices

Confirm blade and rotating-part guards are fitted and move freely.
Check that guards have not been removed or wedged open.
Never pin or wedge spring-loaded guards open; they must snap back over the blade automatically.
Verify safety triggers, locks and dead-man switches work.
Confirm anti-kickback and riving knives are in place where fitted.
Check warning labels are present and legible.
Verify required PPE such as eye and hearing protection is available.

Electrical and GFCI

Confirm power tools are used with GFCI protection.
Test the GFCI device trips and resets correctly.
Verify double-insulated tools show the marking and are intact.
Check outlets and connections show no signs of overheating.
Confirm tools are unplugged before changing bits or blades.
Verify damp or wet conditions are controlled before use.

Pneumatic, cordless and records

Inspect air hoses, couplings and fittings for leaks and damage.
Confirm air tools have safety clips or whip checks on connections.
Check battery packs and chargers for damage or swelling.
Swollen, cracked, or excessively hot lithium-ion battery packs present a severe fire risk; retire them.
Verify batteries seat securely and hold a charge.
Tag out and remove any defective tool from service.
Record defects and replacements, then sign, date and file.

Check that hand and power tools are in good working condition and safe to use with this tool inspection checklist. It covers hand tools, power tool bodies, cords and plugs, guards and safety devices, GFCI protection, and pneumatic and cordless tools, with a clear pass or fail standard for each item.

Damaged tools cause a large share of preventable injuries. A cracked handle, a frayed cord or a missing guard turns a routine task into a hazard, so a quick inspection before use protects the operator and everyone nearby.

Use this checklist for daily pre-use checks and periodic tool audits by operators, supervisors and maintenance staff. Mark each item, remove and tag out any defective tool, and replace or repair it before it returns to service.

Print the checklist for the toolroom or job box, or download the PDF to complete on a phone or tablet and keep with your tool records. These checks supplement, and do not replace, the manufacturer's instructions, OSHA requirements and inspection by a qualified or competent person.

Regulatory basis: OSHA 29 CFR 1926.300(a) requires all hand and power tools to be maintained in a safe condition, and 29 CFR 1910.242(a) makes the employer responsible for the safe condition of tools, including employee-owned ones. Construction sites must protect receptacles with GFCIs or an assured grounding program (1926.404(b)(1)). Rules change and vary by jurisdiction — confirm against the current regulation text, your employer's procedures and the manufacturer's manual.

FAQ

What is a tool inspection checklist?

It's a list used to verify hand and power tools are safe before use, covering damage, cords, guards, GFCI protection and function. Each item is marked pass or fail so defective tools are removed from service.

How often should tools be inspected?

Inspect tools visually before each use, and run a more thorough periodic audit of shared and power tools on a regular schedule. Inspect again after any drop, overload or sign of damage.

Why is GFCI protection important for power tools?

A ground-fault circuit interrupter cuts power quickly if current leaks to ground, protecting against electric shock. OSHA requires GFCI protection or an assured grounding program for power tools on construction sites.

What should I do with a damaged tool?

Remove it from service immediately, tag it out, and either repair it through a qualified person or destroy and replace it. Never use a tool with a damaged cord, cracked housing or missing guard.

What should happen to a tool that fails inspection?

Tag it out of service immediately and keep it out of use until it is repaired or replaced — OSHA requires tools to be kept in a safe condition, so a damaged tool shouldn't go back on the job.

What are the essential checks to perform before using any tool?

Before starting work, check four key areas: physical integrity (inspect handles and housings for cracks or looseness), safety devices (ensure guards and interlocks are functioning), operating condition (verify sharp, secure blades or bits and smooth trigger action), and connections (inspect electrical cords, plugs, or air hoses for wear or damage). Never use improvised or damaged equipment.

What specific defects should you look for when inspecting striking tools?

When checking striking tools like hammers, sledges, and pickaxes, inspect the head for mushrooming, cracks, or severe chipping that could send metal fragments flying. Ensure the head is firmly wedged onto the handle with no wobble. Check wooden handles for splits or splinters and fiberglass handles for fraying or deep gouges. Replace loose or damaged handles immediately.
