In hot metal work situations a combination of Personal Protective Equipment (PPE) is required, Primary and Secondary PPE .
Primary PPE is the outer safety clothing or equipment worn over secondary PPE. Primary PPE is required wherever there is a significant risk of exposure to radiant heat, molten metal splash, sparks/slag and other related dangers. Primary PPE takes the brunt of the hazard. This type of PPE is typically worn when dealing with these specific heightened hazards.
Examples of primary PPE include aluminized coats, jackets, leggings, aprons, sleeves, spats, full and half hoods, safety glasses, face shields, hard hats, hearing protection, gloves or mitts. Ideally both primary and secondary PPE should be worn together wherever Primary clothing is required.
Secondary PPE protection is defined as clothing or personal protective equipment designed as basic protection for continuous use in areas where intermittent exposure to hot metal hazards is possible but less likely. Secondary main purpose is to prevent ordinary clothing from igniting and continuously burning. This type of safety apparel is typically worn for the entire shift. Common types of secondary PPE used in foundry operations are flame-resistant cotton, wool, and specialty inherently flame resistant fabrics. Secondary clothing is also an excellent choice to wear underneath Primary clothing where Primary PPE is required.
Typical minimum specialized secondary clothing and personal protective equipment (PPE) for all melting and pouring operations include the following basic protection:
- 100% cotton or flame resistant cotton blends
- Wool or wool blend outer garments
- 100% cotton or wool socks
- 100% cotton or flame resistant cotton blend undergarments
- Safety glasses with side protection
- Leather safety shoes with toe protection and a smooth toe
