Employers are required to develop and implement a written fire prevention plan (FPP) whenever a workplace activity or process is covered by an OSHA standard that requires one. Standards that require FPPs include 29 CFR 1910.1047-Ethylene Oxide, 1910.1050-Methylenedianiline, and 1910.1051-1,3 Butadiene. An FPP is a hazard prevention plan that ensures advanced planning for evacuations during fires and other emergencies.
