SHOP SAFETY RULES AND REGULATIONS

1.       Avoid horseplay during laboratory and practical work period. It will help you save your limbs and your life.

2.      Work on instrument/machine when required by the instructor.

3.      Read instructions or procedure on your work carefully. Your lack of understanding will mean materials wastage and possible accident.

4.      Refrain from switching ‘on’ a circuit, when putting ‘on’ a switch or circuit breaker. Be sure no one is working on it.

5.      After wiring a circuit verify your work with your instructor before connecting to the source of power.

6.      Electronic instrument and equipment are delicate and expensive. Read all instructions or modules and safety precaution in using them. When in doubt consult your instructor.

7.      Do not work on electrical circuit or any connection with wet hands or wearing wet clothes when power is ‘on’.

8.      When working on a high voltage source, do not wear clothing with expose zipper, metal button or other metallic fasteners.

9.      Avoid wearing loose or flappy clothing.

10.   Wear shoes with sewed socks for work on live electrical circuit when voltage is above 50 volts. Thin solid shoes with metal are prohibited.

11.    Wear rubber shoes gloves if you are likely to come in contact with live conductors current carrying parts or where the voltage exceeds 50 volts.

12.   Protective equipment must be inspected for defects. Such defective equipment must be togged and turn in for repair or replacement.

13.   Danger sign and suitable guards shall be provided to warn others who might come in contact with live parts circuit with voltage exceeding 50 volts.

14.   Tools and equipment containing metal parts should not be used in or with 1 foot of electrical equipment or wiring with exposed current carrying parts.

15.   Continual inspection of with awareness of the danger of accident ground and short circuit is necessary for electrical workers. Dangerous condition should be reported immediately and should be corrected before any further work is done in the area.

16.   Never replaced blown fuses with a coin for socket type fuse or wire for cartridge type of fuse.

17.   Use the proper fuse size or rating for circuit.

18.   Use fuse puller in removing or replacing fuses from the fuse panel where the circuit voltage exceeds 150 volts.

19.   Do not attempt to test voltage with your finger. This is dangerous practice and as strictly forbidden on circuit under 650 volts. Use voltmeter to determine whether the circuit is alive.

20.  Do not twist insulation when electrical work is formed. Insulation may appear to be in perfect condition but in reality maybe defective. Serious injuries and electrical shock may result these.

21.   Before working on a circuit the switches must be togged with ‘hold card’ bearing the following words: this circuit was ordered open for repair and should be or not be used except in direct order of the undersigned if possible padlock switches at ‘off’ position.

22.  Defective or broken sockets switches and receptacles should not be used.

23.  In replacing fuses and repairing electronics and electrical circuit, stand on a piece of dry wood or rubber mat to prevent shock. Always switch ‘off’ before repairing.

24.  Electrical devices should be based on their designed current that is designed for AC to DC operation.

25.  Avoid experimenting with high voltage circuit unless you understand what you are doing.
