Material Safety Data Sheet

SECTION 5 – Fire Fighting Measures 

General Information: During a fire, irritating/toxic sulphur oxides may be generated. 

Sulphuric acid reacts violently with water and organic materials with the evolution 

of heat. Fire may result due to the heat generated by contact of 

concentrated sulphuric acid with combustible materials. Reacts 

with most metals, especially when diluted with water; this reaction produces highly 

flammable hydrogen gas that may explode if ignited. Strong dehydrating agent. 

Containers may explode in the heat of a fire. Firefighter's normal protective clothing 

(Bunker Gear) will not provide adequate protection. A full-body encapsulating 

---

chemical protective suit with positive pressure self-contained breathing apparatus 

(SCBA) may be necessary. 

Extinguishing Media: Use extinguishing media most appropriate for the surrounding 

fire. Carbon dioxide. Dry chemical power. Do not use water. 

Auto-ignition Temperature: Not available. 

Flash Point: Not available. 

NFPA Rating: Health 3; Flammability 0; Instability 2; Other WATER REACTIVE. 

Explosion Limits: Lower: Not available. Upper: Not available.
