For elevated temperature materials, what must be included on the shipping paper?

• A. The color of the packaging
• B. The vapor pressure
• C. The word 'HOT' preceding the PSN
• D. The date of manufacture

Answer: (C)

The essential idea here is warning handlers and responders about a burn hazard from materials that are hot. When you’re shipping elevated temperature materials, you must place the word HOT directly before the proper shipping name (PSN) on the shipping paper. This quick, visible cue alerts anyone handling or responding to a release that the material is at elevated temperature and can cause burns or dangerous reactions, so they take the appropriate precautions (special handling, PPE, and careful loading/unloading). Packaging color, vapor pressure, or date of manufacture don’t convey that immediate heat hazard on the shipping paper, so they aren’t required for this purpose.
