Molten materials

Hazard Knowledge

Molten materials such as metal and glass may be found in industry. Depending upon the substance, maintaining it in a molten state is likely to require extreme heat.

Although they may cool quickly, their liquid state will allow them to travel freely, causing damage and potentially starting fires.

Depending upon their temperature, molten materials will radiate extreme heat and will cause severe burns if contact with them is made.

Molten metals

The metals involved may react with water, releasing hazardous gases or more heat. Due to their extreme heat, contact with water may cause a violent reaction, quickly turning water into steam and the metal to be projected or to spit. For further information refer to the supplementary information for Molten metals.

Molten glass

Sudden cooling may present a risk of projectiles being formed, but there is no risk of chemical reaction with water.
