Guidance: Dry Chemical fire suppression is generally recommended for Sulfur (S8). *Please consult your raw material manufacturer's safety data sheet (SDS) and your local authority having jurisdiction to verify the most adequate fire suppression extinguisher for your specific storage or use.
Additional extinguishing notes: SMALL FIRES: Any extinguisher suitable for Class B fires, dry chemical, CO2, water spray, fire fighting foam, or gaseous extinguishing agent. LARGE FIRES: Water spray, fog or fire fighting foam. Water may be ineffective for fighting the fire, but may be used to cool fire-exposed containers.
Always confirm extinguishing agents against the manufacturer SDS and your authority having jurisdiction before specifying a rental building fire-suppression package.
