1Under the OSHA Hazard Communication Standard (29 CFR 1910.1200), how many sections must appear on a standardized Safety Data Sheet (SDS)?

A.10 sections

B.12 sections

C.16 sections

D.20 sections

Explanation: The GHS-aligned HazCom 2012 standard requires 16 standardized SDS sections: (1) Identification, (2) Hazard Identification, (3) Composition, (4) First-Aid, (5) Firefighting, (6) Accidental Release, (7) Handling and Storage, (8) Exposure Controls/PPE, (9) Physical/Chemical Properties, (10) Stability/Reactivity, (11) Toxicology, (12) Ecological, (13) Disposal, (14) Transport, (15) Regulatory, (16) Other Information.

2Which SDS section contains exposure limits (PEL, TLV), engineering controls, and required PPE?

A.Section 2 — Hazard Identification

B.Section 8 — Exposure Controls/Personal Protection

C.Section 11 — Toxicological Information

D.Section 15 — Regulatory Information

Explanation: Section 8 of the SDS provides exposure control information including OSHA PELs, ACGIH TLVs, NIOSH RELs, recommended engineering controls, and PPE selection criteria. This is the primary section practitioners use when selecting respiratory protection and other PPE.

3Under RCRA, a waste exhibits the characteristic of ignitability (D001) if it is a liquid with a flash point below what temperature?

A.100°F (38°C)

B.140°F (60°C)

C.180°F (82°C)

D.212°F (100°C)

Explanation: Under 40 CFR 261.21, a liquid waste is characteristically ignitable (D001) if its flash point is below 140°F (60°C), excluding aqueous solutions with less than 24% alcohol by volume. Flash point is measured using a Pensky-Martens closed-cup or Setaflash tester.

4A waste is considered characteristically corrosive (D002) under RCRA if its aqueous pH is:

A.≤2 or ≥10

B.≤2 or ≥12.5

C.≤4 or ≥10

D.≤5 or ≥9

Explanation: Per 40 CFR 261.22, a waste is characteristically corrosive (D002) if it is aqueous with a pH ≤2 or ≥12.5, OR if it is a liquid that corrodes SAE 1020 steel at a rate greater than 6.35 mm (0.25 inch) per year at 55°C.

5The four RCRA characteristics of hazardous waste are ignitability, corrosivity, reactivity, and:

A.Radioactivity

B.Toxicity

C.Flammability

D.Infectivity

Explanation: The four RCRA hazardous waste characteristics are ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity (D004-D043). Toxicity is determined by the Toxicity Characteristic Leaching Procedure (TCLP) under 40 CFR 261.24.

6Which DOT hazard class covers flammable gases such as propane and hydrogen?

A.Class 1

B.Class 2

C.Class 3

D.Class 4

Explanation: DOT Hazard Class 2 covers gases. Division 2.1 is flammable gases (propane, hydrogen, acetylene), 2.2 is non-flammable/non-toxic gases, and 2.3 is toxic gases (chlorine, anhydrous ammonia in some jurisdictions).

7Which DOT hazard class includes explosives?

A.Class 1

B.Class 2

C.Class 5

D.Class 9

Explanation: DOT Class 1 covers explosives and is subdivided into Divisions 1.1 (mass explosion hazard) through 1.6 (extremely insensitive). All Class 1 materials require specific placards and are subject to strict transportation rules under 49 CFR 173 Subpart C.

8DOT Class 7 materials are:

A.Oxidizers

B.Radioactive materials

C.Corrosives

D.Miscellaneous hazards

Explanation: DOT Class 7 is radioactive materials. Class 5 is oxidizers/organic peroxides, Class 8 is corrosives, and Class 9 is miscellaneous. Radioactive shipments require activity-based labels (Radioactive I-White, II-Yellow, III-Yellow) and Transport Index on the label.

9What is the purpose of the Emergency Response Guidebook (ERG)?

A.To train new employees on hazmat

B.To provide initial response guidance for first responders in the first 30 minutes of a hazmat incident

C.To serve as the official SDS for DOT

D.To list all hazardous waste codes under RCRA

Explanation: The ERG, published by PHMSA/DOT every 4 years, is designed to give first responders initial action guidance in the first 30 minutes of a hazmat incident. It allows identification by UN/NA number (yellow section), material name (blue), hazard class/guide (orange), and isolation distances (green).

10Which section of the Emergency Response Guidebook lists materials alphabetically by name?

A.Yellow section

B.Blue section

C.Orange section

D.Green section

Explanation: The ERG Blue section lists materials alphabetically by shipping name. Yellow lists by UN/NA number. Orange contains the numbered response guides (111, 112, etc.). Green provides initial isolation and protective action distances for highly toxic substances.

About the CHMP Exam

The CHMP certification from IHMM validates front-line hazardous materials expertise for practitioners who handle, transport, store, sample, and respond to hazmat daily. Unlike the management-focused CHMM, the CHMP emphasizes hands-on technical competency across hazard identification, emergency response, sampling and analysis, site remediation, worker health and safety, and compliance program execution.

Frequently Asked Questions

How many questions are on the CHMP exam?

The IHMM CHMP exam contains 120 multiple-choice questions, with four answer options per question. Some questions may be unscored pretest items used to validate future exam forms, but candidates cannot distinguish them during the test.

What score do I need to pass the CHMP exam?

The CHMP uses a scaled scoring system. Your raw score is converted to a scaled score between 0 and 1000, and you need a 700 scaled score to pass. This accounts for slight variations in difficulty across exam forms.

How long is the CHMP exam and where is it taken?

The CHMP exam is 3 hours long and delivered through the Kryterion HOST proctored network at over 450 computer-based testing centers worldwide, or via online remote proctoring. IHMM introduced online-proctored exams to expand access beyond physical test centers.

What are the eligibility requirements for CHMP?

CHMP candidates must have: (1) an associate degree in applied science or a related field plus 3 years of relevant hazmat experience, (2) a bachelor's degree plus 2 years, or (3) a high school diploma plus at least 6 years of documented hazmat experience. All applications require third-party employment verification.

How is the CHMP different from the CHMM and AHMM?

CHMP (Practitioner) is for front-line technical professionals who handle hazmat hands-on. CHMM (Manager) is the senior management-level credential requiring a bachelor's degree plus 4 years of management-scope experience. AHMM (Associate) is the entry-level credential for those building into the CHMP or CHMM.

How much does the CHMP exam cost?

The total cost is $695: a $175 nonrefundable application fee plus a $520 examination fee. IHMM members receive reduced rates. Additional fees apply for rescheduling, retakes, or international testing locations.

How do I maintain my CHMP certification?

CHMP holders must recertify every 5 years by earning 200 Certification Maintenance Points (CMPs) through continuing education, professional practice, publications, teaching, or IHMM volunteer service. Failure to meet CMP requirements results in certification lapse.

What regulations are most heavily tested on the CHMP?

HAZWOPER (29 CFR 1910.120), Hazard Communication (1910.1200), RCRA hazardous waste (40 CFR 260-279), DOT hazmat (49 CFR 100-185), Respiratory Protection (1910.134), Confined Space (1910.146), and CERCLA/SARA/EPCRA emergency planning. Expect scenario-based questions that integrate multiple regulations.
