How do you document reactivity hazards in a facility?

• A. SDS, chemical compatibility charts, process safety analyses (HAZOP/LOPA), labeling, and risk assessments.
• B. Only SDS and labeling.
• C. Temperature logs and humidity records.
• D. Insurance risk assessments only.

Answer: (A)

Documenting reactivity hazards requires a comprehensive, multi-source approach that captures both the information about each chemical and the safeguards in place across the process. Safety Data Sheets provide the fundamental hazard data for each substance, including information on reactivity risks, incompatibilities, and conditions that can trigger dangerous reactions. Chemical compatibility charts concretely show which chemicals should not be stored or combined, helping prevent reactive pairings before they happen. Process safety analyses, like HAZOP and LOPA, systematically examine the entire process to identify where reactive events could occur and what layers of protection or controls are needed to mitigate them. Labeling communicates critical hazards to workers at the point of use, ensuring that reactivity risks are visible in everyday operations. Risk assessments tie these pieces together by evaluating likelihood and consequence, documenting existing controls, identifying gaps, and setting accountability for ongoing monitoring and improvement. Put together, this framework provides a robust, defensible record of reactivity hazards and how they are controlled, which is why it’s the best way to document these risks. A narrower approach—relying only on SDS and labeling, or on logs or insurance assessments—misses important aspects of how reactions can occur in actual operation and how they are prevented.
