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.
