Illinois Hazardous Materials Technician Certification Examination Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- Which regulation primarily governs hazardous materials response
operations in Illinois?
A. OSHA 1910.134
B. EPA 40 CFR 112
C. OSHA 1910.120
D. NFPA 1001
OSHA 1910.120 establishes requirements for hazardous waste and emergency response, forming the legal foundation for hazmat technician competencies.
- Which level of protection provides the highest respiratory and skin
protection? 1 / 4
- Level C
- Level D
- Level A
- Level B
- The primary purpose of the incident command system (ICS) at hazmat
Level A uses fully encapsulating suits with SCBA, providing maximal protection against vapors and liquids.
incidents is:
- Provide medical triage
- Establish organized command and control
- Build public relations
- Manage fuel budgets
ICS ensures coordinated operations, safety oversight, and structured decision-making.
4. A Safety Data Sheet (SDS) Section 9 provides:
- First aid
- Hazards identification
- Handling and storage
- Physical and chemical properties
Section 9 contains boiling point, vapor pressure, density, and similar properties essential for predicting behavior.
5. BLEVE refers to: 2 / 4
- Biological spill expansion event
- Boiling liquid expanding vapor explosion
- Basic liquid emissions volume estimate
- Ballistic level explosive velocity
A BLEVE occurs when a pressurized liquid vessel fails, releasing superheated vapor explosively.
6. The hot zone is defined as:
- Equipment staging
- Area with the highest contamination risk
- Rehabilitation area
- Media briefing location
- Which detection instrument measures flammable vapor concentrations
- pH paper
- Combustible gas indicator (CGI)
- Colorimetric tubes
- Photoionization detector
The hot zone contains the product or highest contamination concentration and requires maximum PPE.
as a percentage of LEL?
A CGI is specifically designed to display values relative to the lower explosive limit. 3 / 4
- The difference between vapor pressure and boiling point is important
because:
- Determines PPE color
- Predicts soil absorption
- Indicates volatility and likelihood of becoming airborne
- Shows pH behavior
Higher vapor pressure or lower boiling point means a substance readily forms vapor, increasing inhalation risk.
9. Corrosives with a pH below 2 are considered:
- Neutral
- Weak acids
- Strong acids
- Bases
A pH <2 denotes strong acidic corrosion hazard.
10. A hazardous materials technician’s primary function is to:
- Maintain fire apparatus
- Provide patient transport
- Stop or control the release of hazardous materials
- Issue evacuation orders
- / 4
Technicians perform offensive operations aimed at leak control and product containment.
