how often should fire alarm battery be changed?
Technically you can't ask the principal to pull the fire alarm for a fire drill. Usually the maintenance will activate the alarm, but they don't actually pull it, they have a key for the alarm and they can open it and there is a switch that you flip and that activates the alarm.
be sure to include safety goggles, closed toe shoes (no sandals), girls must have their hair pulled back out of their faces, no lose clothing, no running in the lab, no eating during a lab experiment, no leaving burners on, no mixing things that you arent supposed to (follow directions), clean up when you are finished, wear gloves if working with chemicalsetc google chem safety for more
Stay awake and in your house 24/7. Start screaming real loud if you see or hear something.
