Hazardous materials are indicated by which indicators?

• A. Placards (diamond-shaped signs), markings, shipping papers, SDSs, or storage containers
• B. Temperature gauges
• C. Noise levels
• D. Lighting color

Answer: (A)

Hazardous materials are identified through standardized indicators that communicate what substance is present and its hazards so staff and responders can take appropriate actions. Placards on containers or vehicles, markings on packages, shipping papers that accompany shipments, Safety Data Sheets (SDSs), and clearly labeled storage containers all convey essential information such as hazard class, handling requirements, and emergency procedures. Together, these indicators enable rapid recognition, proper containment, PPE decisions, spill response, and evacuation if needed. In a correctional setting, this is vital for safely storing cleaners, fuels, pesticides, and other hazardous substances and guiding staff during any release or exposure. Temperature gauges, noise levels, and lighting color do not identify the material or its hazards and thus are not reliable markers of hazard presence.
