Safety rules/precautions are the rules and regulations guiding the movement and behavior of individual in the workshop to avoid vital accident. The following are the safety rules for bench workers:
- If chips are likely to fly, wear goggle.
- Always hold the work piece securely in the vice.
- Never use a chisel which has developed a mushroomed head.
- If a workplace is hot, mark it in some ways to indicate the facts to others.
- Always use a brush to remove chippings or filings. Do not use your hands to blow.
A WORKSHOP is a place where activities such as fabrication, designing, construction and drawing take place. It has an office, a toilet, a machine section and a store.
There should be a first aid box, work-benches and machines in it.

WORKSHOP SAFETY RULES AND REGULATION (BENCH WORKERS)
Safety means protection from, or not being exposed to the risk of harm or injury.
- Carry out all your activities with care and caution.
- All accidents whether minor or fatal must be reported.
- You must always wear goggles and nose mask during welding, drilling and metal or wood cutting.
- Return all tools and accessories to their proper storage areas after use.
WORKSHOP SAFETY RULES AND REGULATION (MACHINES)
- Safety goggles should be worn when performing machining operations to protect the eyes from flying particles.
- Loose-clothing should be worn in order to prevent being caught by revolving parts of machines.
- Before operating any machines, time should be taken to make sure that the machines are completely in order.
- No attempt should be made to remove chips from the machine with hands.
- No attempt should be made to stop machines with hands even when the power has been switched off.
- Avoid touching any moving parts of the machine and do not lean on it.
- Workshop/machines must be cleaned each day after work.
*Students should comport themselves properly while in the workshop.
WORKSHOP SAFETY DEVICES
To maintain safety in the workshop, practical safety devices should be provided and used to protect delicate parts of the body. These include:
- Hand gloves: To protect the palms and fingers
- The shield or safety goggles: To protect the eyes.
- Boots / Hard sole shoes: To protect the legs, the feet and the toes.
- The Helmet: To protect the head.
- Overall: To protect the chest and body generally.
- Nose mask: To protect the nose from inhaling dust.
- Fire extinguisher and sand buckets: These are to be used to stop fire from destroying lives and property.
Safety Rules for Machine Users
- Never indulge in horse play in a machinery workshop or in the metal workshop in general.
- Never operate a machine unless you have been properly instructed in its use.
- Always ensure you are properly dressed for the job in hand. Always wear some type of eye protection when using machines especially grinding machines.
- It is very important to read the maker’s instructions on all packed goods before opening or unscrewing stoppers on new machines even if you think you know the procedure. It is possible that the makers have amended their instructions since your last reading.
- Never clean the machine when it is on motion.
