Which of the following is NOT a recommended PPE during heat treatment processes?

During heat treatment processes, personal protective equipment (PPE) is crucial for ensuring safety against high temperatures, sparks, and molten materials. Each type of recommended PPE serves to protect different areas of the body from specific hazards associated with heat treatment.

Leather aprons, heat-resistant gloves, and full face protection are all designed to protect the wearer from burns and other injuries due to heat exposure. Leather aprons help shield the torso and legs from splashes of hot materials or sparks. Heat-resistant gloves provide protection to the hands while handling hot items, ensuring that skin is not exposed to extreme temperatures. Full face protection, such as face shields or safety goggles, guards the eyes and face from intense heat, radiant heat, and potential debris that could cause injury.

In contrast, wearing a short sleeve shirt does not offer adequate protection during these processes. It leaves the arms exposed, significantly increasing the risk of burns or injury from hot materials or sparks. Full arm coverage is vital in heat treatment settings to ensure that the skin is not exposed to hazardous conditions. Thus, the short sleeve shirt is considered unsafe and is not recommended PPE for these operations.
