Casting work environment and thermal stress

The human body is a wonderful machine, capable of great things. However, it should always be the perfect balance. For example, changes in temperature mean the body has to adapt in order to survive.

Foundry furnaces and molten metal create a very hot working environment. Additional heat sources are created by heating the mold and core, preheating the ladle, and heat treating the metal casting. Workers engaged in slagging furnaces and ladles, and those working near molten metal experience the most severe heat exposure.

Heat stress usually begins as profuse sweating and rashes, but if left unchecked, it can lead to heat cramps, exhaustion, and in extreme cases, heat stroke. can lead to confusion, muscle spasms, and even death.
