"Did You Know?

 • Some chemicals, especially when heated, can decompose, creating more heat and even exploding.

• Chemical reactions may continue at a slower rate below the usual reaction temperature and reach decomposition conditions given enough time.

• Chemical reactions can take place where they are not expected – like distillation columns or storage tanks.

• During shutdowns there may be distractions; crews may be performing different tasks or be working in different areas.

• Procedures may lack detail for nonstandard operations like temporarily idling or shutting down with materials still in the process."
