CHEMICAL USE

• Do not pour any chemicals down the sink.

CHEMICAL USE

• Take only the amount of chemicals that you need. • Share – don’t be greedy!

GreedySmurf

• Be careful not to cross-contaminate your chemicals.

• When mixing chemicals, always add the water first.

CHEMICAL USE

• This prevents the chemical from splashing.• In some cases the large volume of water absorbs heat that may be generated when the two substances combine.

• If something enters your eye, have a partner direct you to the eye wash station. • Position face above the station with eyes open for 10 minutes.

• Immediately inform your teacher and place injury under running water for 5-10 minutes.

• Immediately inform your teacher, clean the cut and put a bandage on it.

INJURIES

• Put back all equipment where you got it, if you do not have to wash it.

• Spray then wipe down lab bench with paper towel.
