TCFP Hazardous Materials Operations Exam
QUESTIONS AND DETAILED SOLUTIONS JUST
RELEASED
TCFP Hazardous Materials Operations Exam preparation package. It includes a detailed, point-form
summary of the exam coverage based on NFPA 470 (formerly NFPA 472) and TCFP (Texas Commission
on Fire Protection) requirements
POINT-FORM SUMMARIZED EXAM COVERAGE
• Exam Format & Logistics (TCFP):
o Provider: TCFP computer-based exam
o Total Questions: Approximately 50 (Operations level)
o Time Limit: Typically 1–1.5 hours
o Passing Score: 70%
o Renewal: Every 3 years with continuing education or re-examination
o Prerequisite: Hazardous Materials Awareness level certification
• Core Knowledge Domains – NFPA 470 (Operations Level):
o Roles & Responsibilities: Mission-specific defensive actions, protection of people,
property, environment; containment, confinement, decontamination basics
o Analyzing the Incident: Using the ERPG and PAC levels, recognizing container
shapes/damage (bulging, discoloration), identifying hazardous materials by placards
(DOT) and UN/NA numbers
o Emergency Response Guidebook (ERG) Use: Yellow (ID # index), Blue (material name
index), Orange (guides), Green (initial isolation zones)
o Personal Protective Equipment (PPE): Chemical protective clothing (Levels A, B, C, D),
limitations, donning/doffing, air-purifying respirators (APR) vs. SCBA, APR limitations
(cannot be used in IDLH)
o Decontamination (Decon): Types (emergency, mass, technical, gross), decon corridor
setup, avoidance of cross-contamination
o Hazard Control Zones (Hot, Warm, Cold): Definitions, activities permitted in each,
access control
o Air Monitoring: Use of multi-gas meters (O2, LEL, CO, H2S), interpretation of readings
(O2 <19.5% = deficient, >23.5% = enriched, LEL >10% = potentially explosive)
o Response to Specific Incidents: Flammable liquids/gas, corrosive materials, oxidizers,
radioactive materials, biological agents
o Incident Command System (ICS): Unified command, safety officer, decon group, hazmat
branch
o WMD / CBRNE: Secondary devices, chemical warfare agents (nerve, blister, choking,
blood)
o Reporting & Documentation: Bill of lading, shipping papers, safety data sheets (SDS)
• Key Terminology & Concepts:
o Boiling Liquid Expanding Vapor Explosion (BLEVE): Sudden vessel rupture from heat
o LEL / UEL: Lower and upper explosive limits (gas concentration range for flammability)
o Vapor Density: Heavy vs. light vapors (heavier than air sink)
o Water Solubility: Determines if water can be used for dilution
, Page 2 of 117
o Specific Gravity (liquid): Floating vs. sinking
o Decontamination Corridor: Hot → Warm → Cold line; runoff containment
• Emergency Response Guidebook (ERG) – Operations Level:
o Yellow Section: 4-digit UN/NA number index
o Blue Section: Alphabetical chemical name index
o Orange Section (Guides): Emergency actions, fire response, spill response, first aid
o Green Section (Initial Isolation Zones): Table of initial isolation and protective action
distances
• Defensive Control Tactics:
o Absorption (pads, booms)
o Diking, damming, diverting (for liquid spills)
o Vapor suppression (foam, water fog)
o Ventilation (natural, mechanical, hydraulic)
o Leak control (remote valve shutoff, patching) – only if trained
• Medical Monitoring:
o Signs/symptoms of exposure (headache, dizziness, respiratory distress)
o Treatment limitations (supportive care, oxygen, transport)
• Legal & Regulatory:
o OSHA 29 CFR 1910.120 (Hazwoper)
o SARA Title III (community right-to-know)
o DOT Hazardous Materials Regulations (49 CFR)
o TCFP Administrative Rules (specific to Texas)
• Mission-Specific Competencies (TCFP Operations):
o Mass decontamination
o Evidence preservation (criminal/terrorism scenes)
o Interfacing with law enforcement
o Atmospheric monitoring
o Product control (defensive)
o PPE donning/doffing
1. According to NFPA 470, the primary mission of a Hazardous Materials Operations level responder is:
A) Aggressive entry into the hot zone for rescue
B) Defensive actions to protect people, property, and the environment
C) Offensive control of the leak using specialized tools
D) Decontamination of contaminated victims only
Answer: B
, Page 3 of 117
Rationale: Operations level responders are trained for defensive actions (containment, confinement,
protection). Offensive actions (plugging, patching) require technician level.
2. A shipping paper for a hazardous material is also known as a:
A) Safety Data Sheet (SDS)
B) Bill of lading (freight) or dangerous cargo manifest
C) ERG guide page
D) NFPA 704 label
Answer: B
Rationale: Shipping papers include bills of lading, manifests, etc., and must accompany hazardous
materials shipments.
3. The Isolation and Protective Action Distances table is found in which section of the ERG?
A) Yellow
B) Blue
C) Orange
D) Green
, Page 4 of 117
Answer: D
Rationale: The green-bordered section provides initial isolation and protective action distances.
4. A responder using the ERG finds a guide number in the yellow section. Which section contains the
actual emergency actions for that guide number?
A) Orange
B) Blue
C) Green
D) White
Answer: A
Rationale: The orange-bordered section contains the numbered guides with fire, spill, and first aid
actions.
5. The blue-bordered section of the ERG is used to find a hazardous material by:
A) UN/NA number
B) Chemical name (alphabetical)
C) Guide number
D) Initial isolation distance
