Laboratory Safety Flashcards
(28 cards)
TRUE/False
You can work alone in the Laboratory
False
Do not work alone in the laboratory
T/F
Always perform an experiment as specified
TRUE
What is the proper sash work height in a fume hood?
46 cm
True/False
It doesn’t matter how fast you work in a fumehood
False
Use slow and direct movement when working in a fumehood. Fast movement distrupts airflow
A chemical that causes an adverse immune response
Allergen
The entry of a liquid or solid chemical into the trachea and lower respiratory
system through the oral or nasal cavity or from vomiting.
Aspiration
A chemical that causes cancer or increases its incidence in humans or animals
Carcinogen
A chemical that causes destruction of living tissue at the site of contact.
Corrosive
A chemical or mixture of chemicals that produces a damaging release of energy
and gas when detonated by ignition, shock, or high temperature
Explosive
A chemical that is easily ignited and burns rapidly. (Inflammable is a synonym;
it means the same thing.)
Flammable
A chemical that causes reversible damage, such as redness, swelling, itching, or
a rash at the site of contact.
Irritant
A chemical that causes tears
Lachrymator
The concentration of a chemical in air or water that causes the death of 50%
LC50
The amount of a chemical, given all at once, that causes the death of 50% (one
half) of a group of test animals
LD50
A chemical that increases the occurrence of mutations in populations of cells or
organisms
Mutagen
A chemical with structure R!O!O!R, which can explode upon concentration
or sudden shock.
Organic peroxide
A chemical that can rapidly bring about an oxidation reaction by supplying
oxygen or receiving electrons.
Oxidizer
An extremely toxic chemical.
Poison
A chemical that, within 5 min, spontaneously catches fire in air
Pyrophoric
A thermally unstable chemical that is liable to decompose in a strongly
exothermic fashion in the absence of air. (In the GHS this excludes explosives,
organic peroxides, and oxidizers.)
Self-reactive
A chemical that causes an adverse immune reaction upon repeated exposure.
Sensitizer
A chemical that causes physical defects in a developing fetus
Teratogen
A chemical that causes adverse health effects in humans or animals
Toxic
Organic waste containing fluorine, chlorine,
bromine, or iodine.
Halogenated waste
