The most important Lab Safety Rule…….. Always follow directions
Goggles Goggles should always be worn when chemicals are used, heated, or mixed.
Chemical Rules: If you get chemicals in your eyes or on your skin, wash for 15 minutes. Never EVER point a test tube or bottle that you are heating toward yourself or anyone else.
Chemical Rules: If you need to smell a chemical, hold it 6 inches away from your nose and wave the fumes toward your nose. NEVER smell chemicals directly!!!!
Cleanliness: Your lab area should always be clean when you start a lab and when you finish a lab. If a toxic substance was used, follow proper disposal directions
Just say NO: Horseplay is NEVER allowed in the lab. If you are caught horse-playing you will be kicked out of the lab. Food, drinks or gum is NOT allowed to be out during a lab.
Dress Code: Always tie long hair back Closed-toe shoes only No loose clothing; roll baggy sleeves up tight
Fire: If there is a fire in the room, notify the teacher IMMEDIATELY. If the fire is on you……..
Always remember: Its better to be safe than sorry Tell the teacher if any accident occurs
