Lesson 5: Safety
Meet
Lyn.
A few years ago Lyn was participating in an activity in
her science class. She was instructed to blow out her
candle and return it to the lab supply bench by
walking around the outside of the student tables.
After removing her goggles, Lyn blew out her candle
(which was still hot) and walked directly through the
student tables toward the supply bench. Her hot
candle passed over the container of alcohol, dripped
hot wax into the alcohol and caused an alcohol
explosion. Lyn’s hair was burned and her long sleeve
caught on fire burning her arm.

COMPRESSED Gases = gases (like oxygen, nitrogen,
hydrogen, etc.) that are stored under pressure in a
tank.
If the valve is damaged the
tank can explode or become a
projectile.
Personal Protective Equipment (PPE) = equipment such
as eyewear (goggles), clothing (lab coats, aprons), gloves
(heat protectant, neoprene).
Fume Hood = a vacuum to remove harmful chemical
fumes/vapors.
So, how do you safety smell chemicals?
Wafting = the safe way to sample a chemical aroma is to
use your hand to waft the fumes toward your nose.
What if this was chloroform?
She could end up like this!
