FIRE FIGHTING ACUTE HAZARDS TYPES OF HAZARD

NO water. In case of fire in the surroundings: powder, foam, carbon dioxide 

Not combustible. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. 

FIRE

In case of fire: keep drums, etc., cool by spraying with water but NO direct contact with water. 

Risk of fire and explosion on contact with base(s) , combustible substances , oxidants , reducing agents or water .

Packaging & labeling

Storage Spillage disposal

Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs. Note: B C symbol R: 35 S: 1/2-26-30-45 UN Hazard Class: 8 UN Packing Group: II 

Separated from combustible and reducing substances, strong oxidants, strong bases, food and feedstuffs , incompatible materials . See Chemical Dangers. May be stored in stainless steel containers.

Store in an area having corrosion resistant concrete floor

.  Keep container tightly closed. Keep container in a cool, well ventilated area.

Stop leak if without risk. Absorb with inert material. Do not get water inside container. Do not touch spilledmaterial. Use water spray curtain to divert vapor drift. Use water spray to reduce vapors. Prevent entry intosewers, basements or confined areas; dike if needed. Neutralize the residue with a dilute solution of sodium

carbonate  .

Environmental considerations

Prevent from entering in public sewers or the immediate environment.

Do not empty into drains, dispose of this material and its container to hazardous or special waste collection

Point according to Hazardous Waste Regulations.

Attention Concretes made of cement are highly alkaline

with pH values normally above 12.5 and are not easily attacked by acidic solutions. As the pH of the solution decreases the equilibrium in the cement matrix is being disturbed, and the hydrated cement compounds are essentially altered by hydrolytic decomposition which leads to the severe degradation.

Taking sample from sulfuric truck to detect the iron in sulfuric sample, Rust is an iron oxide, usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture.
