## Annual Refresher Training

**Tools and Machine Guards**

## Hazard Recognition

- Tools are common in “day-to-day” life
- Difficult to spot hazards due to familiarity
- Most tools manufactured with safety devices
- Users must inspect the tool daily
- Tools are often misused

- Tools and equipment used on the job can be dangerous devices.  Even a simple hand tool can cause injury. Workers with little or no training are the highest risk for injury

## Examples of Misuse

- Using a screwdriver as a chisel
- Using tools with loose handles
- Wrenches with sprung jaws

## Hand Tools Safety

- Regular plastic dipped handles on hand tools are not for working on electrical equipment.
- If a wooden handle on a tool, such as a hammer or axe is loose, splintered or cracked, the head of the tool may dislodge from the handle.
- A wrench must not be used if its jaws are sprung.
- Impact tools, such as chisels, wedges or drift pins are unsafe if they have mushroomed heads. The heads may shatter on impact, causing sharp fragments to disperse

## Power Tools Safety

## Five Basic Rules with Power Tools

- Keep all tools regularly maintained
- Use the right tool for the job
- Examine each tool for damage before use
- Operate tools in accordance with the manufacturer
- Provide and use the proper personal protective equipment

## Precautions

- Never place your finger on the start button while carrying a power tool.
- Never try to alter a tool to complete a task it was not designed for perform.
- Never remove a guard from a tool or machine.

## Personal Protective Equipment

- Use proper gloves when applying any chemical
- Wear the appropriate safety glasses/goggles when using hand tools
- Use the proper respirator when working with power tools that may produce respiratory hazards
- Spark shield and protection around flammables
- Don’t use tools near aisle ways

## Equipment & Machine Safety

**Proper Tool Storage**
- When finished using a power tool, disconnect it immediately from its power source
- Do not wrap the electric cord around the tool because it may cause the cord to wear or break

**Working at Heights**
- Never work directly above someone.
- Do not carry tools up ladders, instead use a hoist or rope to lift your tools.
- Be aware of where your tools are at all times** **

## Equipment & Machine Safety

- Operate them within their design limitations
- Gloves and footwear are recommended
- When they are not in use, store them in a dry location
- Do not use them in wet or damp location
- Work areas should be well lighted

## Machine Guard

## Protective Guards

**Guards are required for:**
- Pinch, shear, or in-roll points.
- Shaft ends exposed more than 1⁄2 the diameter or have rough areas, such as gears, chains, pulleys, rope pulls and fan blades.
- Electrical circuits.

## General Guard Safety Requirement

- Prevent body contact with dangerous moving parts
- Guards must be durable and firmly secured to the machine.
- Unplug the machine before attempting to conduct repairs.
