SAFETY AND SECURITY RULES TO BE FOLLOWED IN LABORATORY:

1. Always wear shoes before entering in the lab.

2. Do not touch anything without the permission of instructor/ lab assistant.

3. Read carefully the lab manual before performing experiments.

 4. Do not tamper measuring instruments.

 5. Do not open the casing of the equipment.

 6. Switch off the power supply to the experimental setup on completion of the experiment.

7. Maintain clean and orderly laboratories and work area.

8. Be aware of the various experiment controls (start button, stop button, speed control) for each experiments.

9. Do not leave experiments running unattended.

10. Any injuries should be reported immediately for proper care.

GENERAL INSTRUCTIONS

1. Enter in lab with closed footwear.

2. Boys should tuck in the shirts.

3. Long hair should be protected, let it not be loose specially near rotating machineries.

4. Any other machines/ equipment should not be operated other than the prescribed one for that day.

5. Power supply to your test table should be obtained only through the lab technician/ instructor.

6. Read carefully the lab manual before performing experiments.

7. Do not lean and do not be close to the rotating components.

8. Tools, apparatus and gauge sets are to be returned before leaving the laboratory.
