FIREFIGHTER HAZMAT TEST BANK
QUESTIONS AND ANSWERS
(GRADED A+)
nonionizing radiation - Answer-least energetic and visible light or radio waves. Waves
composed of oscillating electric or magnetic fields
Four types of ionizing radiation - Answer-Alpha beta gamma neutron. All are extremely
hazardous
Alpha radiation - Answer-Positively charged, emitted from nucleus of heavy r.d.
elements like uranium. Lose energy rapidly cant penetrate skin. So, not hazard outside
body.
Beta radiation - Answer-Pos or neg, emitted from nucleus of Tritium or carbon 14. Fast
moving, penetrate skin and cause radiation damage. Travel 20ft
Gamma radiation - Answer-high energy photons that accompany alpha or beta. Highly
penetrating and can inflict sever radia damagae. Standard ppe is not enough
Neutron radiation - Answer-MOST Dangerous, produce by fission reactions. Dificult to
measure. Very hazardous to health
Exposure - Answer-Contact with hazardous material, causing biological damage.
Routes of entry - Answer-inhalation, ingestion, skin contact, injection, absorption and
penetration
Asphyxiants - Answer-Prevent body from absorbing oxygen, nitrogen
Corrosive material - Answer-chemical that severely corrodes steel and damages human
tissue
Systemic effect - Answer-Damage spread through an entire system
IDLH - Answer-Immediately Dangerous to Life and Health
Corrosives - Answer-chemicals that cause permanent damage to anything they touch
Irritants - Answer-cause temporary but sometimes severe inflammation to the eyes,
skin, or respiratory system
