Toolbox Talk: Power Tools

Introduction

It is crucial that everyone in the workplace is aware of the potential hazards of using power tools as well as being competent at using the tool. It is easy to forget just how dangerous they really can be if not used or maintained properly.

Some common causes of power tool accidents are:

• inattention through complacency
• inexperience
• overconfidence
• occurrence of an unexpected event.

Common Types of Power Tools

The most commonly used power tools in construction are electric power tools, power cutting tools, and pneumatic tools (compressed air).

Electric Power Tools

These include various types of drills, saws, grinders, cords, and plugs.

Some common injuries include electric shocks, eye injuries from ejected of particles, and cuts.

Cutting Tools

These include various types of power saws. When operating a power saw, always secure the material being cut. Have stable and even footing and always use both hands while operating. Make sure all saws have working guards in place.

Pneumatic Tools

These are tools powered by compressed air. Compressed air can blast out at extremely high speeds which is a safety hazard, along with the hazards already inherent in fast, sharp, and powerful tools. Compressed air must never be directed at any persons, including the operator.

IDENTIFY the right tool for the right job

Before starting work with a power tool, you should check you're using the right tool for the right job.

In some cases, the environment may pose a risk when using a certain tool.

Make sure:

• Work surfaces are stable and clear of other material that may fly off
• There are no pipes or other electrical wiring that could cause a risk
• There is no explosive or flammable gas, dust, or vapour - particularly if using tools that create sparks
• Work surfaces are stable - for example, never work on a ladder while using a power tool
• There are no obstacles in the area that you could trip on.

Once you've chosen the right tool for the job visually inspect it prior to it being used.

ASSESS the training

Powered tools should only be used by a person who is competent to use it. The training should cover:

• the care, use, and maintenance of the tool
• how to check it before use, e.g., test tags, guards or shields
• safety precautions.

Your local equipment Sales Representative is often a good source of training.

ASSESS use of correct PPE

Eyes and ears are most at risk when using power tools - from the risk of dust and noise. It's important that operators are wearing:

• Appropriate eye protection, ensuring it fits correctly. NB: A full-face shield may be needed.
• Appropriate hearing protection to avoid noise-induced hearing loss.
• If appropriate, a respirator - particularly if the operation will generate dust. This is a greater risk when cutting concrete. (See Toolbox Talk #8 Dust)
• Make sure there are no loose items of clothing or jewellery.

Keep others on site well away from the work area and where possible put a sign up to indicate a power tool is in use.

MANAGE with frequent checks

For all tools you should:

• Inspect them immediately prior to use for any defects.
• Repair or replace all worn or damaged components immediately - label any damaged tools and tag them 'DO NOT USE'
• Check all guards are in place, are secure, and in good working condition.
• Check the test tag date.
• Always store your site's power tools in a secure place when they're not in use.

Quick reminders

• Ensure workers operating the tools are competent to operate the tool.
• Inspect daily for any defects before using tools.
• Check safety mechanisms are working.
• When using nail guns. ensure the area behind or underneath are clear of workers.
• In addition to usual PPE, use eye and hearing protection as appropriate.
• Remove power packs from tools when not in use.
• Load tool where it will be used and immediately prior to its use, unload after use and before cleaning or packing up.
• Never underestimate the recoil power of tools.

Q and A

• Ask your team to name the common types of power tools
• What is the appropriate PPE gear when using the various power tools on your work site?
