Perform only those experiments authorized by the instructor;

Do not eat food,drink beverages or chew gum in the lab;

Absolutely no horseplay in the lab!

When checking a chemical for odors, gently waft vapors towards nose; NOYES

Double check labels on chemical bottles Take only as much chemical as you need; Never return unused chemicals to their original containers;

When diluting acids always add the acid to the water; –“Do as you oughta – add acid to water”

Never handle broken glass with your bare hands; –Use a dust pan and brush –Place broken glass in glass disposal container

Never use chipped, cracked or dirty glassware; Never leave a lit burner unattended; When heating a substance in a test tube, never point the mouth of the test tube at yourself or others;

Never look down into a container that is being heated; Be careful – hot glass doesn’t look hot!
