EE Lab Safety Policy and Measures
1. No food or beverages are permitted in the EE Labs. 2. Only students scheduled for a lab session are allowed in the EE Labs. 3. Locate the nearest exit and fire extinguisher. Never work alone in the EE Labs. 4. Do not adjust the metal shelf position. Do not move equipment. Use caution
when re-positioning equipment on the metal shelves to prevent equipments from
5. Turn off power before plugging, unplugging, or re-positioning equipments. 6. Use the correct lead/plug/probe for the equipments. Do not use alligator clips on
the equipments. Use caution to prevent metal leads from touching each other.
7. Do not pull on the power cord. Plug and unplug using the power cord plug. 8. Do not attempt to repair any equipment. Do not open the chassis of any
equipment. Report all equipment defects or safety issues to the lab technician.
9. Make certain that the power supply is off before connecting power leads to the breadboard or disconnecting power leads from the breadboard.
10. Turn off power to the breadboard before inserting or removing components. 11. Power supply voltages should be increased slowly while monitoring for high
12. Turn off power immediately, if any component becomes hot or begins smoking. 13. Do not exceed the voltage and/or power rating of electrical components. Be very
careful to observe the polarity of electrolytic capacitors, which can explode if
connected the wrong way.
14. Do not place your face directly over the breadboard when powering-up. Safety glasses are recommended for eye protection; regular glasses are acceptable.
15. Do not work with wet hands. 16. Avoid metal jewelry which may dangle or fall onto electrical circuits. Long hair
and loose clothing can cause hazards if tangled with circuits or equipments.
