Laboratory Safety Flashcards
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
Collected in flammable waste if it is not
halogenated or nonaqueous (without water) organic waste
containers.
Organic waste
Collected separately from organic
waste because it can react violently with some organic
reagents and because it is treated differently upon storage and
disposal.
Aqueous (water) waste
Consists of spent drying agents, filter paper coated
with solvents, filter paper used in recrystallizations, and solid
material remaining after a reaction.
Solid waste
Waste containing heavy metals, such as
chromium and mercury
Toxic metal waste
