2. Work shop safety rules
The first step in developing a safe work environment is to have procedures in place which provide guidelines for students to perform various tasks safely.
The procedure should help eliminate injuries by providing rules and guidelines for people working on or near energized electrical circuit conductors.
It should address qualifications, tools, protective equipment, approval levels and attendance required for various tasks, as well as other additional cautionary information.

3. Con’t
Also, this procedure should address safe approach distances for qualified and unqualified personnel.
Before you can use equipment and machines or attempt practical work in a workshop or a lab, you must understand basic safety rules.
These rules will help keeping you and others safe in the workshop.
Following safety rules will also prevent you and others from accidents, injuries as well as death.

4. Con’t
In general, Safe working habits in work shop is essential to prevent accidents which may result in personal injury or health hazards, damage to tools, equipment and property.
Common causes for accidents are:
Improper use of tools and equipment’s, etc.
Failure to use protective equipment
Protective and safety equipment that has been rendered inoperative
Failure to follow correct procedure

5. Cont.. Faulty equipment and tool
Condition of walking and working surfaces
Unguarded or inadequately guarded machinery
Safety is a matter of common sense and good work habit. A person who does not have knowledge of or regard for his tools, machines, equipment and himself cannot effectively and safely perform his work.

6. Con’t
A good knowledge of tools is very important for safety. Any tool can cause harm if not properly used.
So any one who uses tools must use them carefully and safely to avoid injury.
Anyone who knows about safety rules takes good care of himself and the tools.
He can avoid the danger that may be caused by carelessness and ignorance. Report any unsafe conditions, equipment, or work practices as soon as possible.

7. Safety rules that need to be observed in the electric work shop
1. Never turn on power line without the permission of the instructor
2. No horseplay in the electric work shop
3. All tools must be used for the purpose that they are designed for
4. Handle sharp-edge or pointed- tip tools such as pocket knife, chisels, with care.
5. Safety procedure stated in all laboratory activities must be strictly observed
6. Keep your work area hazard free
7. Keep tools and cords away from heat, oil and sharp edges that can damage electrical insulation

8. Con’t 8. Never touch live wire or any other current carrying parts
9. Do not use electrical equipment in damp or wet areas
10. Do not use electrical equipment on or near metals, which conduct electricity
11. Do not over load circuits
12. Every circuit must be fused
13. Never experiment with circuits unless you understand what you are doing
14. Bare wires must be insulated to avoid short circuits

9. Safety measures in handling of tools
1. Handle sharp edge tools with special care a) Never carry them unshielded in pockets without their cover b) When you give a sharp-edge tool to another person, pass its handle first, never with the cutting edge first. c) Avoid placing your fingers or hands in the path of motion of the cutting tool d) Be on guard at all times against slipping of sharp edge tools.

11. Storage of tools
1. Tools may be stored horizontally or vertically depending on the construction and safety requirements 2. Tools must not be exposed to an environment, which shortens there service span (example damp area) 3. Tools must be stored so that they may be easily accessible and easily noticed when missing 4. Chemicals and inflammables must be stored in restricted areas. 5 the worker must inspect all protective facilities before doing any job
