OSFM HAZMAT STATE EXAM STUDY GUIDE – HAZARDOUS MATERIALS OPERATIONS & TECHNICIAN
TRAINING – OSFM CERTIFICATION PREPARATION – COMPLETE EXAM REVIEW AND PRACTICE NOTES
1. Acute Exposure: Short Contact with chemical, it may last seconds or few hours (Single occurrence)
2. Chronic Exposure: Long term exposure
3. Name of Contamination Zones: Cold Zone - No contamination (Awareness)
Warm Zone - Decon Zone (Operations)
Hot Zone - Contaminated Area (Technician)
4. Level A Suit: Hot Zone, Fully encapsulated with w/ SCBA. High Hazards with respiratory, skin, and eyes
5. Level B Suit: Hazmat identify but not require a high level of skin protection. Protects against liquid splash
protection but no protection against vapors, same respiratory protection, but not same skin protection
6. Level C Suit: Same as B but lower-level respiratory protection. Suit otters liquid splash protection but not
to chemical vapors or gasses. Most common use in workers today. Wear in a site where chemical(s) will not attect
skin and when air contaminants and the site hazards have been characterized. C is not allowed by OSHA for Chem
Emergency Response.
7. Level D Suits: No respiratory protection. Used when an atmosphere contains no known hazards. Bunker gear
is Level D
8. Types of tankers and what they carry (what carries chlorine, name of tanker
with rings, which one has vents out the top, what type carries propane): MC 331:
Carries Chlorine and Propane
MC312/DOT412 has the heavy reinforcement Rings
MC306/DOT406 is a low pressure that has vents
9. What level of O2 is dangers: 19.5%
10. Know direct contact compared to contamination: Contamination is hazardous material
that physically remains on a person, animal or object.
Direct contamination results from direct contact with a contaminant or through cross contamination
11. What tanker carries 6,300 gallons and works between 14 and 25 psi
(IM-something): IM-102 [IMO Type 2] carries 6300 and works between 14 to 25 psi
12. The physical changes to the material caused by the chemical, which can
include swelling, stiffening, wrinkling, changes in color, and other physical
deterioration: Degradation
13. What level do you wear in the decon zone in the warm zone: One below than the
Hot Zone (level B)
14. What's it called when you have to go a fast decon: Emergency Decon
15. Name for cancer causing stuff: Carcinogen

16. If there is no operations chief, who do you respond to: Incident Commander
17. If you don't have the right materials to stop contamination what do you
do?: Retreat to safe distance
18. If a guy is diking, damming, etc. he taking what type of measures: Defensive
19. 3 types of dams. Complete Dam, Underflow dam and dam: Overflow
20. What senses is safe that can you use to spot a hazard: Sight and sound
21. What book do you use for BLEVE: ERG
22. 4-5 ERG question: White: Intro, Instruction, Guidance, Placards, and more
Yellow: Materials order by 4-digit UN/NA number
Blue: Materials ordered by dangerous good name
Orange: Safety procedure and direction. Initial response phase
Green: Evacuation and protective action distance
23. What do you do first when putting on Level A: Medical examination,. checking gear, and
having a safety debrief
24. What's another name for a "fully encapsulated suit": Level A
25. How to approach a scene: uphill and upwind
26. Minimum suit for an unknown substance by OSHA: Level A
27. Material that attacks breathing: asphyxiation
28. Debriefing, what can you use in case radio does not work: Hand Signals
29. Chemical passes through a material on a molecule level?: Permeation
30. Difference Between Laws, Regs, and Standards: Law- Created by legislative body
Regulation - Created by government agency
Standard- Created by nongovernmental body
31. First Law regulated how emergency response to Hazmat incident: SARA (Super-
fund)
32. Who should be on local emergency planning committee?: EMS, Health community,
Media, Industry, Environmental group
33. Key info on Tier 2 form: Chemical Name, Storage Amount in a range, location, emergency contact
34. Key component of Hazmat communication standard: OSHA 1910.120. MSDS required
to be available for first responders
35. Three components of HAZWOPER/EPA/OSHA: Requires certain training, standard operat-
ing guidelines, and certain rules to be followed for chemical release situations
