Part of the EMS Operations practice questions exam area.
This page holds 200 free practice questions for Chapter 50, Hazardous Materials, covering hazmat regulations and training levels, placards, NFPA 704, safety data sheets, and the ERG, scene control and hot, warm, and cold zones, chemical properties and exposure limits, PPE levels and entry-team medical monitoring, emergency, gross, technical, and mass decontamination, corrosives, toxic gases, cyanide, organophosphates, and hydrofluoric acid, and radiation basics, clandestine drug labs, and hospital notification. They are written for paramedic and EMT students working through Nancy Caroline's Emergency Care in the Streets, 9th edition. Every question shows the correct answer with a short explanation as soon as you tap, so you learn while you test rather than waiting until the end.
Study it two ways: the 10 Question Blitz, a quick round where every right answer lights a siren and any misses lead into Lights & Sirens, a 5-in-a-row drill on that section, or the full 100-question test drawn at random from the whole chapter. After each test you get a score and a section-by-section breakdown. Progress on the full test is saved on your device, so you can stop and pick up later.
The OSHA regulation that sets training and safety rules for workers who respond to hazardous materials releases is:
Answer: A. 29 CFR 1910.120, known as HAZWOPER
HAZWOPER (Hazardous Waste Operations and Emergency Response) sets OSHA's training levels, PPE, medical surveillance, and response-plan rules for hazmat responders. The bloodborne pathogens standard is the common mix-up because it is also an OSHA rule, but it covers infection control, not chemical releases.
On an NFPA 704 diamond, the blue section at the left indicates the material's:
Answer: D. Health hazard
The NFPA 704 diamond shows health in blue (left), flammability in red (top), instability in yellow (right), and special hazards in white (bottom). Red is often guessed for health because it signals danger, but red is flammability.
A tank truck has crashed on a bridge, and a liquid is pouring into the creek below. Along with staying upwind, your ambulance should approach from:
Answer: D. Upstream of the spill
Liquids carried by moving water travel downstream, so responders approach and stage upstream as well as upwind and uphill. Crossing the bridge or working on the bank below puts the crew in the product's path.
Most students use the 10 Question Blitz for daily practice and take the full 100-question test in the days before a class exam or NREMT practice. Lights & Sirens after a blitz is the fastest way to close gaps the night before a test.
Every question in this chapter is also listed by section, with answers, on the topic pages above. See all paramedic topics or take the NREMT paramedic practice test.
