Lab Manual

Be calm and relaxed, while working in lab. First check your measuring equipment. When working with voltages over 40 V or current over 10 A , there must be at least two people in the lab at all time.
Keep the work area neat and clean. Be sure about the locations of fire extinguishers and first aid kit. No loose wires or metals pieces should be lying on the table or neat the circuit. Avoid using long wires, that may get in your way while making adjustments or changing leads.
Be aware of bracelets, rings, and metal watch bands (if you are wearing any of them). Do not wear them near an energized circuit.
