CHMM EXAM STRUCTURE

The CHMM (Certified Hazardous Materials Manager) exam is designed to assess the knowledge and competencies of professionals in hazardous materials management, environmental safety, and related areas. It is administered by the Institute of Hazardous Materials Management (IHMM). Below is the detailed structure of the CHMM exam:

Exam Format

  • Type: Multiple-choice
  • Number of Questions: 160 questions (140 scored + 20 unscored pre-test questions)
  • Time: 3 hours to complete
  • Scoring: Only the 140 scored questions count toward the final score, while the 20 pre-test questions are unscored. Candidates will not know which ones are pre-test.
  • Language: English
  • Computer-based Test: Administered at approved testing centers

Exam Content Outline (Domains)

The CHMM exam tests knowledge across several domains that reflect the key areas of hazardous materials management and environmental safety practices. The exam content is divided into the following domains:

A. Regulatory Overview (24%)

  • Federal, state/provincial, and local regulations (e.g., RCRA, CERCLA, DOT, OSHA, TSCA, FIFRA)
  • International regulations (e.g., Basel Convention, REACH, IMDG)
  • Environmental laws and regulations (e.g., Clean Air Act, Clean Water Act)
  • Waste management regulations (hazardous waste, non-hazardous waste, solid waste)

B. Hazardous Materials Management (26%)

  • Hazardous materials identification, classification, and labeling
  • Chemical properties and hazardous characteristics (e.g., flammability, corrosivity)
  • Hazardous materials storage, transportation, and disposal
  • Hazardous materials spill and emergency response
  • Industrial hygiene and occupational health risks associated with hazardous materials

C. Hazardous Waste Management (20%)

  • Hazardous waste generation, storage, and disposal methods
  • Waste minimization and pollution prevention strategies
  • Treatment, storage, and disposal facilities (TSDFs)
  • Land disposal restrictions (LDRs) and hazardous waste treatment technologies

D. Hazard Assessment and Risk Management (15%)

  • Risk assessment methodologies (e.g., HAZOP, fault tree analysis, failure mode analysis)
  • Hazard analysis and risk management planning (e.g., process safety management)
  • Exposure assessment and health effects of hazardous materials
  • Safety data sheets (SDS) and chemical inventories

E. Remediation (10%)

  • Site assessment, remediation, and cleanup techniques (e.g., excavation, bioremediation)
  • Contaminated site management, including soil and groundwater remediation
  • Brownfield redevelopment and site restoration strategies
  • Decontamination and demolition procedures

F. Occupational Health and Safety (5%)

  • OSHA regulations and compliance (e.g., hazard communication, respiratory protection)
  • Personal protective equipment (PPE) requirements and safety protocols
  • Monitoring and sampling of air, water, and soil for hazardous materials
  • Health risk prevention and safety training programs for employees

Passing Score

The exam uses scaled scoring, and the minimum passing score is set at 650 out of 1000. This ensures consistency in exam difficulty, meaning the raw score needed to pass may vary slightly between different exam versions, but the scaled score ensures fairness.

Preparation

  • Study Materials: The CHMM Candidate Handbook and the CHMM Blueprint are essential resources for exam preparation, as they outline the exam structure and provide guidelines on subject areas to focus on.
  • Courses and Workshops: Many candidates attend preparatory courses, workshops, or seminars that focus on hazardous materials management, regulatory compliance, and environmental safety.
  • Practice Exams: Mock exams and practice questions help candidates familiarize themselves with the exam format and question style.

Certification Maintenance

To maintain CHMM certification, professionals must earn continuing education units (CEUs) and submit documentation to the IHMM as part of their re-certification process, which occurs every 5 years.

Understanding the structure and content domains of the CHMM exam will help guide your study plan and ensure you are well-prepared for this certification. Buy a CHMM certificate without exam stress in Saudi Arabia, Canada and the USA.
