Special Fire Fighting Procedures

In itself, quicklime is incombustible. If it comes in contact with water or humid air it hydrates, evolving heat. Heat could ignite paper, wood, or rags.

Unusual Fire and
Explosion Hazards

Water on quicklime causes an exothermic reaction, as noted above.

Stability

Unstable: Yes
Conditions to Avoid:
Coming into contact with water, humid air or acids.

Stable: Yes       
If no moisture or acids are present.

Incompatibility: Materials to Avoid

Should not be mixed or stored in contact with chemicals that are moist or have water of hydration.

Hazardous Decomposition

Health Hazards
(Acute and Chronic)

Under hot humid conditions quicklime can cause skin burns to a perspiring work or skin irritation. Can be irritating if inhaled, causing sneezing.

Waste Disposal Method

Salvage for use or remove to dump. Do not place where heat of hydration by contact with water could ignite adjacent materials such as wood or paper.

Precautions to Be Taken in Handling and Storing

Do not store near acids or chemicals, which are moist or contain water of hydration. Store in a dry area.

Respiratory Protector (Specify Type)

Protective dust mask

Ventilation
