Molten Metal Dispersion Protection

Hazard Definition

Molten metal dispersion is defined as an event where metals, heated to temperatures of 1400o to 1600o Fahrenheit, splash outside their designated container. This type of hazard is present in metal smelting and casting facilities, particularly in the steel and aluminum industries.

The risk to workers is that dispersed molten metal will cling to their clothing and transfer intense heat through that clothing, resulting in severe burns.

Such burns are potentially fatal, and even when they aren’t, can result in trauma effects that typically prevent employees from returning to work, leading to financial and emotional hardships for the employee and their family.

Protection from Hazard

If molten metal comes in contact with specific types of fabric, it will cling to the fabric, rather than roll off. Additionally, any “catch points,” such as open pockets, patches, or raised seams can similarly prevent molten metal from rolling off the garment. Appropriate training and preparation, such as wearing the appropriate Primary Protective Clothing (PPC) for the metal being handled, and other personal protective equipment (PPE) can minimize the effects of a flash fire event.

This is why PPC and PPE are now industry requirements.
