Tool Selection

Non-Powered

Electric

Air Powered

Powder Actuated

Gas Powered

Safety Note: If you have to modify a tool to make it work, you probably don’t have the right one!

Non-Powered Hand Tools

Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads.

Wrenches with sprung jaws should be taken out of service.

Wooden handled tools should be inspected periodically to make sure they are not splintered, cracked, or loose.

Electric Tools

Electric tools are difficult to guard completely

They are subject to more abuse than stationary tools

Cords must be inspected regularly

These tools should be unplugged/battery removed for all maintenance procedures.

Double Insulated Tools

NFPA 70 permits double insulation for portable tools

Third wire grounding is not necessary for double-insulated tools

Double insulation works by isolating the tool’s internal electric components from the outer housing

Circular Saw Safety Tips

Set the blade’s depth to no more than

1/8

” to ¼” greater than the thickness of the material

Avoid binding the blade and causing a “kickback”

Release the trigger if the saw binds or stalls

Never pull the saw out of a cut until the blade stops

Pneumatic Tools

(Nail Guns)

Make sure the nose guard safety spring is functioning properly

Don’t hook up the power source until it is time to nail

If the tool has to be carried while under power, stay away from the trigger and never carry against the body

Safety glasses are a must!

For Framers;

Keep the off hand out of the way

Never nail beyond your reach

Keep the gun properly aligned with the work

Be aware of surroundings and fellow workers

Powder-Actuated Tools

Only employees who have been trained and certified in the operation of the particular tool shall be allowed to operate

Must be tested each day prior to use

If it doesn’t pass inspection, it must be removed from service

All required PPE must be worn

Unfired caps should not be left in the gun or lying around

The loaded tool should never be left unattended

Gas Powered Tools

Types include leaf blowers, trimmers, mowers, and chainsaws.

Follow manufacturers recommendations for service intervals and safe use.

Take special care during refueling.

Give the equipment adequate cool down time.

Use only approved containers for fuel storage.

Never smoke during refueling.
