You should always assume that glassware and metal objects are hot, while working with a heat source.

Safety precautions you should use when working with a heat source are:

• Turn off heat sources when they are not in use.
• Point test tubes away from yourself and others when heating substances in them.
• Use the proper procedures when lighting a Bunsen burner.
• To avoid burns, do not handle heated glassware or materials directly.

Safety equipment you should have in your laboratory are:

• Fire extinguisher is stored in a compartment attached to the wall.
• Red fire alarm is on the wall at eyelevel next to the fire extinguisher.
• Fire blanket is stored inside a labeled red box attached to the wall next to the fire extinguisher. The blanket is to be used on clothing that caught fire. The blanket can also be used to cover a shock victim.
• Safety shower is located next to the lab entrance. When the handle is pulled down, a supply of water will be falling down to flush off the entire body and clothing in case of large serious chemical splashes.
• Fume Hoods are located around the perimeter of the room. These are used to exhaust toxic or nauseous gases from the room.
