Hazmat operations Questions with
Detailed Verified Answers
Carcinogen Ans: — Any material that causes cancerous growths in living
tissue.
Corrosive Ans: — Material that causes visible destruction or irreversible
damage alterations to living tissue by chemical action at the site of
contact.
Lethal Dose (LD50) Ans: — Causes the death of 50 percent of a group of
test animals exposed to it by any route other than inhalation.
Lethal Concentration (LC50) Ans: — The amount of material in the air
that is expected to kill 50 percent of a group (inhalation).
Toxic Ans: — A chemical falling in LD50 or LC50
Irritant Ans: — A chemical that is not corrosive but one that causes a
reversible inflammatory effect on living tissue by chemical action at the
site of contact.
Sensitizer Ans: — A chemical that causes a substantial proportion of
exposed people or animals to develop an allergic reaction in normal tissue
after repeated exposure.
Hepatotoxins Ans: — Chemicals that produce liver damage.
Nephrotoxins Ans: — Chemicals that produce kidney damage.

Blood agents Ans: — Decrease the function of hemoglobin in the blood;
deprive the hemotopolatic body tissues of oxygen system.
Pulmonary agents Ans: — Irritate the lung or damage the pulmonary
tissue.
Reproductive toxins Ans: — Chemicals that affect the reproductive
capabilities, including chromosomal damage and effects on fetuses.
Asphyxiant Ans: — A substance that can cause unconsciousness or death
by suffocation.
Convulsant Ans: — Material that can cause an exposed individual to have
a seizure.
Allergen Ans: — An allergy provoking substance.
Carcinogen Ans: — Any material that causes cancerous growths in living
tissue.
Mutagen Ans: — Causes changes in the genetic system of a living cell.
Teratogen Ans: — Any substance that causes growth abnormalities in
embryos or genetic modifications in cells.
Radiation Ans: — Alpha,Beta particles, Gamma rays and Neutron.
Alpha Particles Ans: — Slow moving, relatively heavy, short range (3
inches). Not considered dangerous unless ingested.
Beta Particles Ans: — Very small, high penetrating power, travel distance
of 7 feet. Can damage skin tissue and can damage internal organs if
ingested or abdorbed.
Gamma Rays Ans: — Most dangerous form of radiation. Originate from
the nucleus of an atom. Move at the speed of light and travel great
