Certified Hazardous Materials Manager Practice Exam 2025 – Comprehensive Test Prep

The correct choice identifies research facilities as not being one of the four main types of hazardous waste management facilities. The four primary categories for hazardous waste management include treatment and storage facilities, disposal facilities, transfer facilities, and a fourth category, which typically refers to waste generation facilities or similar operations.

Treatment and storage facilities are designed to process and hold hazardous waste temporarily to reduce its hazardous nature or volume before disposal. Disposal facilities are the final destinations for waste, designed to safely dispose of hazardous materials. Transfer facilities assist in the movement of waste from one location to another, often serving as a temporary holding area before reaching treatment or disposal sites.

Research facilities do not fall into these categories because their primary purpose is to conduct scientific studies and experiments rather than to manage hazardous waste. While they may generate or handle hazardous materials in the course of their work, they are not classified as facilities specifically for the management of hazardous waste, which is a critical distinction in understanding the structure of waste management operations.
