If your clothing or your neighbor's clothing catches fire, what should you do?

• alert the teacher, drop to the floor and roll to extinguish the fire or grab nearby fire extinguisher

If something on your lab benches catches fire, what is the best response from the choices below?

• always run for the fire extinguisher if you see a flame
• if and only if it is possible to do so safely, cover the flames with a beaker or watchglass, remove solvents from the area, then get the fire extinguisher; if it is not possible to do this, leave the room and pull the fire alarm, and call 911 from a safe phone
• get the safety wash and aim the water at the flames
• the moment you see a hint of the flame, immediately leave the room and pull the fire alarm

• do nothing - it is probably a false alarm
• shut down your experiment, get your stuff, then leave the building
• leave the building immediately following fire alarm protocols
• grab a fire extinguisher and/or safety wash
