General Safety Instructions

The general safety instructions include the following three general categories:

  • Clothing
  • Conduct
  • Chemicals and Equipment handling

Clothing

Approved safety goggles. Long hair must be tied back when using open flames. Contact lenses are not allowed. Even when worn under safety goggles, various fumes may accumulate under the lens and cause serious injuries or blindness.
A shirt that covers the stomach and lower back as well as the upper arms. Long pants (An acceptable, but not reccommended, alternative is to wear shorts, a skirt, or a lab coat such that your knees are covered when you are sitting down.). Never point a test tube or any vessel that you are heating at yourself or your neighbor--it may erupt like a geyser.
Shoes that completely cover the foot. Clean up all broken glassware immediately and dispose of the broken glass properly. Contact the stockroom for clean-up of mercury spills.

Conduct

Eating, drinking, and smoking are strictly prohibited in the laboratory.Coats, backpacks, etc., should not be left on the lab benches and stools. There is a hook rack along the back wall at either end of the lab. There are coat racks just inside the each entrance to the balance room at the back of the lab. Beware that lab chemicals can destroy personal possessions.


Always wash your hands before leaving lab.Notify the instructor immediately in case of an accident.No unauthorized experiments are to be performed. If you are curious about trying a procedure not covered in the experimental procedure, consult with your laboratory instructor.

Never taste anything. Never directly smell the source of any vapor or gas; instead by means of your cupped hand, waft a small sample to your nose. Do not inhale these vapors but take in only enough to detect an odor if one exists.
Learn where the safety and first-aid equipment is located. This includes fire extinguishers, fire blankets, and eye-wash stations.

Chemicals and Equipment Handling

Many common reagents, for example, alcohols and acetone, are highly flammable. Do not use them anywhere near open flames.

Always pour acids into water. If you pour water into acid, the heat of reaction will cause the water to explode into steam, sometimes violently, and the acid will splatter. Excess reagents are never to be returned to stock bottles. If you take too much, properly dispose of the excess.

If chemicals come into contact with your skin or eyes, flush immediately with copious amounts of water and consult with your instructor. Know what chemicals you are using. Carefully read the label twice before taking anything from a bottle. Chemicals in the lab are marked with NFPA hazardous materials diamond labels. Learn how to interpret these labels.

Beware of hot glass--it looks exactly like cold glass. Never leave burners unattended. Turn them off whenever you leave your workstation. Be sure that the gas is shut off at the bench rack when you leave the lab. Dispose of chemicals properly. Waste containers will be provided and their use will be explained by your TA. Unless you are explicitly told otherwise, assume that only water may be put in the lab sinks.

Consider all chemicals to be hazardous unless you are instructed otherwise. Material Safety Data Sheets (MSDS) are available in lab for all chemicals in use. These will inform you of any hazards and precautions of which you should be aware.
