Hazardous Properties of Materials 2025
Expert Verified | Ace the Test
physical hazard - 🧠 ANSWER ✔✔chemical that is classified as posing one of the
following hazardous effects: explosive; flammable (gases, aerosols, liquids, or
solids): oxidizer (liquid, solid, or gas); self-reactive; pyrophoric (liquid or solid);
self-heating; organic peroxide; corrosive metal; gas under pressure; or in contact
with water emits flammable gas
health hazard - 🧠 ANSWER ✔✔chemical that is classified as posing one of the
following hazardous effects: acute toxicity (any route of entry); skin corrosion or
irritation; serious eye damage or eye irritation; respiratory or skin sensitization;
germ cell mutagenicity; carcinogenicity; reproductive toxicity; specific target
organ toxicity (single or repeated exposure); or aspiration hazard.
gas - 🧠 ANSWER ✔✔substance or mixture that at 50C has a vapor pressure greater
than 300 kPa, or is completely gaseous at 20C and a standard pressure of 101.3 kPa

,GHS description
liquid - 🧠 ANSWER ✔✔substance or mixture that is not a gas and has a melting
point or initial melting point of 20C or less at a standard pressure of 101.3 kPa
GHS description
solid - 🧠 ANSWER ✔✔substance or mixture that does not meet the definitions of a
liquid or a gas
GHS description
flammability - 🧠 ANSWER ✔✔A material's ability to burn
three components are needed to sustain a fire: fuel, oxygen, and an ignition source
(heat); fire triangle
pyrophoric - 🧠 ANSWER ✔✔spontaneously flammable

, flammable gases - 🧠 ANSWER ✔✔defined by the percentage of gas in air that will
ignite
- concentration between LEL and UEL
- the wider the flammable range, the greater the risk of fire or explosion
Lower Explosive Limit (LEL) - 🧠 ANSWER ✔✔the lowest concentration of vapor
in air that will burn
Upper Explosive Limit (UEL) - 🧠 ANSWER ✔✔the highest concentration of vapor
in air that will burn
flash point - 🧠 ANSWER ✔✔the temperature at which a liquid produces enough
vapor to ignite when exposed to an ignition source
- the lower the flash point, the greater the fire hazard
boiling point - flammability - 🧠 ANSWER ✔✔flammable liquids with low boiling
points have higher concentrations of vapors in the air and can therefore be more
dangerous than liquids that boil at higher temperatures.
