What hazard occurs if calcium hypochlorite comes into contact with oily rags?

When calcium hypochlorite comes into contact with oily rags, it can lead to ignition and the potential for a flash fire. This is due to the oxidative properties of calcium hypochlorite, which can react vigorously with organic materials, including oils found in rags. The reaction can generate heat and, in the presence of sufficient combustible material, can ignite the oils, causing a fire to erupt.

Calcium hypochlorite is a strong oxidizer, and when it interacts with flammable substances, oxygen is often released, which can further enhance combustion. Therefore, the risk of fire is significant when these materials are improperly stored or used in conjunction with each other.

Understanding the hazards involved with chemicals like calcium hypochlorite is critical for ensuring safe handling and storage practices in water treatment facilities and other environments where these substances are used. This also emphasizes the importance of keeping oxidizers away from combustible materials to prevent dangerous reactions.
