SAFETY IN the CHEMISTRY LAB Everyone is Responsible! "I didn't mean to" and "It wasn't my fault" are two statements that have no place in the lab. Horse-play will not be tolerated.

Laboratory Safety Rules What is wrong with this picture?

Laboratory Safety Rules FIRE SAFETY Learn at once the location and operation of - Fire extinguisher - Fire blanket station - Emergency shower - Eye and face wash fountain - First aid kit In lab work involving the heating of test tube, never look in the test tube while heating it, or point the mouth of the test tube towards any other student. Never use an open flame near a volatile liquid, such as alcohol.

Laboratory Safety Rules Lab Safety Equipment: Eye Wash Station The station should only be used if chemicals come in contact with the eyes. Eyelids have to be forcibly kept open to ensure effective washing. Be sure to wash from the nose out to the ear. This will avoid washing chemicals back into the eye or into an unaffected eye. Flood eyes and eyelids with water for a minimum of 15 minutes.

Laboratory Safety Rules Lab Safety Equipment: Safety Shower The shower provides an effective means of treatment in the event that large amounts of chemicals are spilled or splashed onto the skin or clothing. As long as the hanging handle is pulled down, the safety shower will supply a continuous stream of water to cover the entire body.

Laboratory Safety Rules Lab Safety Equipment: Fire Safety Blanket Fire blankets are not the best means to extinguish a fire. They may be used to extinguish clothing that is burning, but should never be used on any other type of fire. Fire Extinguisher The average fire extinguisher only operates about 10 seconds. Don't waste it! You must get close to the fire - as close as 5 or 6 feet! To effectively operate an extinguisher, think P-A-S-S. P -- pull the pin A -- aim the hose at the base of the fire S -- squeeze the handle S -- sweep the hose back and forth

Laboratory Safety Rules CHEMICAL SAFETY No chemicals may be used until instructor explains the use and cautions to be taken. Never use unlabeled chemicals. Always use caution while transferring reagents from their containers. In the event that spilling might occur, teacher should be notified immediately. Immediately wash with large amounts of water any part of skin, or clothing that comes in contact with strong reagents. Chemicals in the eye must be washed immediately with running water. Do not taste, eat or drink any lab chemicals.

Laboratory Safety Rules CORROSIVE SUBSTANCES Reagents are not to be taken from the laboratory stock stations. Take container to stock stations for materials. Never pour unused reagents back into bottles, exchange stoppers of the bottles, or lay stopper on the table. Never add water to concentrated acid. Large storage bottles of chemical such as acids or alkalis are only to be handled by the teacher.

Laboratory Safety Rules GLASSWARE SAFETY Notify the teacher about all broken glassware. Prevent other students from walking in that area, and above all do not attempt to clean up the broken glass until given instructions and materials for clean up. Never handle broken glass with bare hands. Use counter brush and dustpan.
