4.2 Hand and Power Tools

Tools help us do work that would otherwise be difficult or impossible. Even simple tools can cause severe injury if they are used or kept badly.

Hazards for tool users

• falling or flying objects, which may be abrasive or may splash
• harmful dusts, fumes, mists, vapours and gases
• frayed or damaged cords, hazardous connections and poor grounding

Five basic safety rules

1. Keep all tools in good condition with regular maintenance.
2. Use the right tool for the job.
3. Examine each tool for damage before use.
4. Operate tools according to the manufacturer's instructions.
5. Provide and use the right protective equipment.

Hand tools

Hazards usually come from misuse and poor maintenance. Do not use:

• wrenches whose jaws are sprung
• impact tools such as chisels and wedges whose heads have mushroomed
• tools with loose, cracked or splintered handles
• a screwdriver as a chisel
• tools with taped handles, which may hide cracks

Electric tools

• Operate within design limits.
• Use gloves and safety shoes. Take care with gloves near rotating tools, since a glove can be caught and draw the hand in.
• Store tools in a dry place and do not use them in wet locations unless they are approved for them.
• Light the work area well and make sure that cords are not a tripping hazard.

Employees exposed to falling, flying, abrasive or splashing objects, or to harmful dusts, fumes, mists, vapours or gases, must have the PPE that protects against them.
