Question

What should be social consideration of an electrical engineer student in lab. (Explain in 250 words)

Answer 1

The following are the general or social considerations should be taken by an electrical engineer student in the lab.

1. Avoid contact with energized electrical circuits: .The student should take care, and he has to Treat all electrical devices as if they are live or energized and he should avoid direct contact with those circuits.

2. Disconnect the power source before using electrical equipment. Use only tools and equipment with non-conducting handles when working on electrical devices.

3. Never use metallic pencils or rulers, or wear rings or metal watchbands when working with electrical equipment.

4. When it is necessary to handle equipment that is plugged in, be sure hands are dry and, when possible, wear nonconductive gloves, protective clothes and shoes with insulated soles.

5. Drain capacitor: before working near them keep the short circuit on the terminals during the work to prevent electrical shock.

6. Never touch another person’s equipment or electrical control devices unless instructed to do so. Enclose all electric contacts and conductors so that no one can accidentally come into contact with them.

7. Never handle electrical equipment when hands, feet, or body are wet or perspiring, or when standing on a wet floor.

8. De-energize open experimental circuits and equipment to be left unattended. Do not leave cables and cords unsecured and hanging in areas where they can be damaged. Place cords so that they are not subjected to mechanical stress or temperatures that could damage the insulation.

9. Do not leave electrical circuits exposed. Use electrical tape to insulate wires or use a guard as cover to prevent accidental contact.

10. Do not install standard electrical equipment in locations where flammable gases, vapors, dusts, or other easily ignitable materials are present. If electrical equipment is used in a chemical fume hood, elevate it to allow efficient air flow. Keep electrical equipment at a minimum in high-moisture areas (e.g., wash rooms, cold rooms).

11. Probe hot wires and components with only one hand to prevent current from passing through your chest cavity and injuring your heart. Place the other hand at your side, in a pocket, or in a belt loop away from conducting materials.

12. Use tools designed for electrical work that have a non-conductive cover. Electrically insulated gloves are also available.

13. Use voltmeters with appropriate rating for the voltage to be tested. A standard voltmeter could explode when subjected to a high voltage.
