Maintaining A Safe and Secure Work Environment
- No playing in workshop/work area.
- Ask for permission from teacher/person in charge.
- Ask questions when in doubt.
- Replace/store ALL tools after use.
- Report ALL accidents/injuries to the person in charge.
- Do not place tools in your pockets.
- Always wear proper/safety clothing/gear. Eg (helmet, shoes and overalls etc.)
- Wear gloves when necessary.
- Always keep yours hands dry.
- Do not touch switches, appliances and wires with wet hands.
- Do not leave tools lying on the ground.
- Always turn OFF or unplug electric tools/equipment.
- Do not lift heavy equipment by bending your back. Keep your back straight and bend knees to prevent injury.
- Use all tools correctly.
- Never assume that wires/circuits are dead.
- Make sure tools have proper insulation/rubber.
- Do not use water to put out an electrical fire.
- Never work alone.
- Always use ladders and scaffolding where necessary.
- Always use proper test equipment to make sure equipment/circuit is DEAD.
Manual Lifting and Handling
Many injuries in industry and in the home are direct result of incorrect lifting and handling.
See Figure 1 below.
Fire Safety
Fire Prevention – it is best not to use naked flames or smoke in certain areas. Turn off ALL appliances after use. Highly combustible/flammable materials should be kept away from any source of heat.
Fire Detection and Control - In order for fire to exist, three properties must be present:
1. Fuel (oil, paper, wood, etc)
2. Oxygen
3. Heat (naked flame, spark, etc)
There are three methods to detect a fire:
1. Human detection
2. Smoke detection
3. Heat detection
There are two methods to control fire:
1. Manual (hand-held extinguishers)
2. Automatic (sprinkler system)
Both of these methods/systems use the same substances (water, foam, etc).

Electrical Safety
1. Never work on live equipment (unless a special live test is required)
2. Always make sure, by using approved test instruments, that equipment is dead.
3. Never accept another person’s word that a circuit is safe to work on…Check it yourself!!!
4. Turn OFF ALL electrical supplies, and put all supply fuses in a safe place. Place ‘CAUTION MEN AT WORK’ notices where necessary.
5. If working on dead equipment when live supplies are nearby, place ‘DANGER LIVE EQUIPMENT’ notices on ALL live equipment.
Safe use of Electrical Equipment
- Make sure tools are in good condition.
- Make sure cord/cables are not damaged in any way.
- Work with 110V instead of 220V whenever possible.
- Inspect and check ALL current-carrying and current-using devices regularly (3-months).
- Make sure all cables exposed to mechanical damage (puncturing, etc) are well protected.
