Chemicals Wash any affected areas immediately with

water and inform your teacher. If you get anything in your eyes, wash them

continuously for 15 minutes. Never smell a substance directly, waft the

fumes towards your nose. Hold containers away from face when pouring

liquids. Never put any chemical back into its original

container. Only put chemicals down the sink or into the garbage with permission.

Hot Plates Use heatproof containers only. Do not allow a container to boil dry. Be careful with a hot plate that looks as

though it has cooled down.

(c) McGraw Hill Ryerson 2007

Open Flames Wear protective gear. Tie back long hair

and loose clothing. Handle hot objects carefully (they may

look cool). Point the open end of container that is

being heated away from yourself and others.

Turn off gas valves or hot plates as soon as you are finished using them.

Apply cold water to burns.http://www.scivee.tv/node/4299

Electrical Equipment Make sure your hands are dry when

touching electrical cords, plugs or sockets.

Pull the plug, not the cord. Report damaged equipment to your

teacher. Place electrical cords where people will

not trip over them.
