2 I. Chemistry Laboratory Regulations General Regulations. The following rules, designed to preserve your health, will be strictly enforced. 1. Eye protection must be worn at all times in the laboratory. Regular glasses do not provide sufficient protection and therefore safety goggles will be required. Never wear contact lenses in the lab; vapors can be trapped behind the lens and cause irreparable corneal damage. Safety goggles are available for purchase at safety- work shops. If you are caught just once not wearing proper protective eyewear in lab, you will be dismissed for the day, and miss finishing that lab. If you are caught twice, you will be dismissed from the lab for the remainder of the course. 2. No one is allowed in the laboratory at any time without proper supervision; i.e., a qualified lab assistant or faculty member must be present. 3. No smoking, food, or beverages are allowed in the laboratory. 4. Shoes must be worn in the lab at all times. Sandals are not allowed because they do not provide sufficient protection from falling equipment and chemicals. 5. Secure long hair behind the head to prevent it from coming near moving equipment or burners. 6. Your clothes must cover the trunk of your body and your shoulders. A lab apron or coat is also required and available for purchase at workplace safety shops. Safety Precautions. 1. Know the location and use of the fire extinguishers, fire blanket, eyewash, safety shower, and first aid kit. 2. Be careful about smelling chemicals; avoid breathing any vapors. Work in a ventilation hood when carrying out reactions involving volatile substances or gases. If you must determine the odor of a compound, fan the vapors towards your nose, and sniff cautiously. Do not taste any compounds; some are toxic or contain toxic impurities. Avoid prolonged exposure (inhalation or absorption through the skin) of organic compounds. Common organic solvents such as acetone, methanol, chloroform, carbon tetrachloride, benzene, aniline, nitrobenzene, phenol, etc. are toxic. Use the hood when possible. 3. When heating a container such as a test tube, do not point the mouth of the container at your neighbors or yourself. The liquid may suddenly boil or bump, causing the liquid to be blown out of the mouth of the container. 4. Always make sure that the apparatus set-up used in an experiment does not involve a closed
