Safety Rules and Measures:

It is extremely important to follow the safety guidelines before you start and during the lab sessions. Some of the rules and measures that you must take are listed below.

1. Wear safety glasses.
2. Remove watches, jewelry, rings, and ties.
3. If you have a long hair, you must tie it up or put it in a cap.
4. Avoid loose clothes, and remove jackets.
5. Wear short sleeves, or properly rolled-up long sleeves.
6. Wear heavy duty shoes.
7. Make sure the floor is dry before you start and stays dry during the lab session. Never start your lab session if the floor is wet or greasy.
8. Familiarize yourself with the location of the emergency stop buttons before you start your lab session.
9. Some labs may require wearing electrically-insulating gloves. Please be aware when they are needed.
10. Perform proper Lockout/Tagout procedures, and inform other students around you and your group members, if you are working in a group, before you plug in or operate, or turn on an electrical equipment.
