Safety Equipment
Safety equipment overview

The following safety equipment is available in the general chemistry lab. Know where it is and how to use it. Your TA will know how, if you are not sure.

During your first lab period, you will be asked to locate each piece of safety equipment in the lab, as well as two exits. This Safety Quiz appears in the front of your lab manual.

Eye Wash
Eye Wash
In the event of an eye injury or chemical splash, use the eyewash immediately.

Help the injured person by holding their eyelids open while rinsing.

Rinse copiously and have the eyes checked by a physician afterwards.

The telephone is in the lab for emergency use only. For emergency requiring fire department or rescue squad, dial 911.
Exits from Lab

Make sure that you know how to exit the lab quickly, in the event of an emergency. You should know two ways to get out.

Safety Goggles
Safety Goggles
You will not be permitted to work in the laboratory without safety goggles. Goggles must be warn at all times in the lab. Do not remove them until you leave the room. Goggles do not provide eye protection when worn on the forehead or around the neck.
Fire Extinguishers
Fire Extinguisher
Your TA has been trained to use fire extinguishers in the lab. In the event of fire, first clear the area, then ask your TA for help.
Using a Fume Hood

A fume hood carries away vapors from reagents or reactions you may be working with. Using a fume hood correctly will reduce your personal exposure to potentially harmful fumes or vapors. When using a fume hood, keep the following in mind.

• Place equipment or reactions as far back in the hood as is practical. This will improve the efficiency of fume collection and removal.

• Turn on the light inside the hood using the switch on the outside panel, near the electrical outlets.

• The glass sash of the hood is a safety shield. The sash will fall automatically to the appropriate height for efficient operation and should not be raised above this level, except to move equipment in and out of the hood. Keep the sash between your body and the inside of the hood. If the height of the automatic stop is too high to protect your face and body, lower the sash below this point. Do not stick your head inside a hood or climb inside a hood.

• Wipe up all spills immediately. Clean the glass of your hood, if a splash occurs.

• When you are finished using a hood, lower the sash to the level marked by the sticker on the side.
