Whenever a continuous bell alarm sounds in the chemistry building:

a. evacuate the laboratory classroom and meet with your lab mates out in the hallway. b. pack up your belongings, evacuate, and gather outside the building in a predetermined area with lab mates.
c. evacuate the building immediately and gather outside the building in a predetermined area with other lab mates.

Whenever a continuous bell alarm sounds in the Chemistry building it is

important to evacuate the building immediately and gather outside the

building in a predetermined area with other lab mates.

The continuous bell alarm sound may be as a result of a fire incident in which

which an individual must not spend any time trying to gather belongings as

the fire may spread rapidly and decrease chances of escape and survival.

Evacuating the laboratory classroom and meeting with your lab mates out in

the hallway is also not safe as the hallway is still within the premises. It is

therefore best to evacuate the building immediately and gather outside the

building in a predetermined area with other lab mates.
