655: Standard for Prevention of Sulfur Fires and Explosions

Effectively mitigate the risks for sulfur fires and explosions using NFPA 655: Standard for Prevention of Sulfur Fires and Explosions.

Use the essential steps and requirements outlined in NFPA 655: Standard for Prevention of Sulfur Fires and Explosions to eliminate or reduce hazards encountered in the crushing, grinding, and pulverizing of bulk and liquid sulfur. NFPA 655 also prescribes the safe handling of all forms of sulfur, including ground sulfur and molten sulfur. The Standard clarifies how to choose between prescriptive or performance-based options when applying NFPA 655.

Changes in the 2017 edition of NFPA 655 help you understand and correctly address all types of hazards.

• Changes to definitions and other material within the Standard correlate with NFPA 654: Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids — the Standard referenced by OSHA’s Combustible Dust National Emphasis Program (NEP) for the purposes of identifying dust hazards and defining mitigation strategies that protect life and property.
• Revisions clarify the scope of the document and its relationship to NFPA 654
• Other changes address requirements for the use of steam in fire fighting

Improve safety around bulk or liquid sulfur using NFPA 655.
