Quiz No. 1

Students should recognize that extended exposure to chronically toxic chemicals can result in cancer or other organ-specific damage, and should be able to identify such compounds.

• toxic substance classifications

• nanomaterials

• acute chemical exposures

• chronic chemical exposures

Both ionizing and non-ionizing radiation, including lasers and ultraviolet lamps.

• Electrical hazards

• Low-pressure and vacuum systems

• Cryogenic hazards

• Radiation hazards

These are chemicals or organisms that increase the rate at which natural biodegradation occurs.

• acids and bases

• biological agents

• compressed gases

• corrosives

These are substances that readily ignite and burn in air spontaneously.

• peroxides

• halogens

• pyrophorics

• mercury

This includes both the chemical hazard of the gases and physical hazard of all parts of the system subjected to greater than 1 bar (>100 kPa)

• low-pressure and vacuum systems

• compressed gases and high-pressure systems

• incompatible chemicals for storage or handling

• Electrical hazards

Chemicals that are easily ignited or explode under usual laboratory working conditions, such as low-molecular-weight alcohols, aldehydes, ketones, and hydrocarbons.

• flammable chemicals

• corrosive chemicals

• acute chemical exposures

• toxic substance classifications

Examples of Halogens

• fluorine

• chlorine

• acetone

• bromine

• iodine

These are most commonly used in the laboratory as solvents.

• flammables

• halogens

• mercury

• peroxides

The practice of handling chemicals in a safe manner, minimizing the hazard to public and personal health.

• chemical safety

• safety data sheets

• laboratory safety

• personal protective equipment

Used to hold or clamp laboratory glassware and other equipment in place, so it does not fall down or come apart.

• beaker tongs

• striker

• scoopula

• ring stand
