What is the best method to control radiant heat?

Using shielding is the most effective method to control radiant heat. Radiant heat is energy that is transferred through electromagnetic waves, which means it can propagate through air and can significantly influence temperatures in work environments. Shielding provides a barrier that reflects or absorbs this radiant energy, thereby preventing it from reaching individuals or sensitive equipment. It can take various forms, including physical barriers such as heat shields made of reflective materials or insulation that can absorb heat.

In contrast, improving air circulation primarily addresses convective heat transfer rather than radiant heat. While increasing ambient temperature does not help in controlling radiant heat, rather it can intensify the exposure. Wearing insulated clothing provides personal protection but may not effectively mitigate significant radiant heat sources in the immediate environment. Thus, shielding stands out as the best method due to its direct effectiveness in obstructing or redirecting radiant heat.
