Methanol, ethanol, acetone, cyclohexane, ethyl acetate. Do not use near open flame or sources of sparks.

Why must chemicals not be taken from the lab?

Most chemicals are dangerous, particularly under non-lab conditions. Furthermore, unauthorized removal is illegal.

Accident: Large Chemical Spill on Floor

Move away from the area of the spill. Warn people around you. Call your TA! Let an expert handle the clean-up! Be prepared to give information to EH&S (name of chemical, location, etc)

Can you spray someone with a fire extinguisher?

No

Why are unauthorized experiments not permissible?

No student knows for certain that an unauthorized experiment is safe to carry out. Discovered infractions will bring severe academic penalties.

Only what type of clothing is safe in a lab? Why?

Non-synthetics which are not frilly or flared and i not have loose sleeves or scarves. Synthetics, in general, burn readily and stick to skin upon melting, causing much worse burns. Avoid bare legs by wearing full length slacks. Ravelled or torn clothing gives little protection and is apt to catch on fire more easily.

Under what conditions only are contact lenses permitted in the lab?

Only if one wears approved goggles or face shield and a waiver form is filled out. Glasses give good protection from splash only at the front. Anything getting under a contact lens will not wash out until the lens is removed. y then the eye will be damaged.

Practice Quiz: What does PPE stand for?

Personal Protective Equipment

Quickly remove any contaminated clothing and rinse yourself off in a safety shower. Use the safety shower. (The treatment for chemical exposure is 15 minutes under cold running water, or as long as you can stand it.)

Practice Quiz: What should you do, if an acid/ base/ chemical comes in contact with your clothes or shoe?

Remove these ASAP Rinse exposed skin area with cold running water (Safety Shower may be required)

Accident: Chemical on Body

Rinse effected area for 15 minutes with cold running water

Accident: Large Fire

SHOUT FOR HELP and leave the area immediately! The fire alarm will probably sound. When it does, evacuate the building and TELL EVERYONE YOU CAN, where the fire is.

Why are smoking, eating, and drinking not allowed in the lab?

Smoking because of the fire hazard; all others because of the possibility of getting chemicals in the mouth.

How can a small, contained fire (eg. in a beaker) be put out easily?

Smother with sufficiently large watch glass or inverted beaker

Injury: Small Burn

Tell your instructor, and let your instructor look at the injury. Chemical burns and heat burns should both be treated with lots of cold running water. Never put anything but cold water on a burn! Doctors often have to remove ointments because they retard healing! After this treatment, if the burn still hurts badly enough that you cannot complete the experiment then you will be escorted to the Student Health Services office so the burn can be treated.

Injury: Large Cut

Tell your instructor, and let your instructor look at the injury. In all cases, a large cut must be attended to by medical professionals! If you can walk, you may be escorted to the Student Health Services office or another Emergency Center. Or you may wait while UB Police and Emergency Medical Service (EMS) team arrives.

Injury: Small Cut

Tell your instructor, and let your instructor look at the injury. Wash the injury thoroughly with water. If the injury is minor you may use a band and continue to work on experiment. If your injury hurts or you feel you should have someone look at it. Then you may be excused and directed to the Student Health Services or another Emergency Center so the cut can be treated

Who should be immediately called for assistance in case of an accident, fire, or injury in the lab?

The TA or staff member at the lab stockroom.

Practice Quiz: What should you do, if an acid/ base/ chemical comes in contact with your hands or face?

The best treatment for any type of chemical spill on the skin is immediate flushing with lots and lots of cool water. Do not wait for it to cause a burning sensation on the skin. Do not try to figure out a way to neutralize the chemical spill; Have a lab mate inform the Lab TA or another staff member.*
