6. No unauthorized experiments are to be performed. Follow directions
carefully, using only the amounts of chemicals specified.
7. Always pour concentrated acid into water; never pour water into the acid.
8. No visitors are allowed in the lab unless specific permission is given by
the instructor.
9. Clean up all chemical or solution spills immediately. Your work area
should always be left clean at the end of the lab period.
10. Protect both hands when you insert glass tubing or thermometers
into stoppers. Make sure the glass is well lubricated before such
insertions are attempted. Your instructor will show you the correct
procedure.
EMERGENCY FACILITIES AND PROCEDURES
Despite safety precautions, accidents sometimes occur. Even though the
chance is small, it is important to know what to do in the event you are
involved. Therefore, you should acquaint yourself with the location and
use of the following emergency facilities. Your instructor will describe or
demonstrate their operation.
1. Safety shower
2. Fire blanket
3. Safety eye-wash facility
4. Fire extinguisher
The following procedures should be followed if you are involved in an
accident. Also be prepared to assist other students in the laboratory. In
some instances, people involved in accidents become disoriented and
frightened and forget what to do. Be ready to help.
1. Report all injuries—no matter how slight—to your instructor.
2. Splashes of corrosive or toxic substances should be washed immedi-
ately from skin and clothing, using copious amounts of cold water.
Speed is especially important if the material has splashed into the eyes.
3. The best immediate treatment for a burn is to hold the injured area
under cold water or to cover it with ice.
4. If your clothing catches fire, use the safety shower or blanket.
5. If a fire occurs on a bench area, use the fire extinguisher.
6. If you cut or burn yourself, call your instructor immediately for first aid.
GENERAL LABORATORY PROCEDURES
The following procedures will help you use your time efficiently and will
help minimize the waste of chemicals and other supplies. Other techniques
will be described to you as needed in later experiments.
1. Cleaning glassware: Scrub inside and out with a brush, detergent, and
tap water. Rinse away all suds with tap water. Rinse the inside of the
glassware two or three times with minimal amounts of distilled water.
(Distilled water is expensive and should be used sparingly.) Shake out
