Why is it important to wear protective clothing when working with urethane materials?

Wearing protective clothing when working with urethane materials is crucial because it helps to avoid skin absorption of dangerous chemicals. Urethane compounds can contain isocyanates, which are known to be harmful and can be absorbed through the skin. This exposure can lead to various health issues, including skin irritations or more severe systemic effects.

Protective clothing, such as gloves, long sleeves, and aprons, acts as a barrier between the skin and the chemicals, significantly reducing the risk of dermal absorption. Focusing on this aspect of safety is essential for anyone handling these materials regularly, as prolonged or repeated exposure can lead to chronic health problems.

While respiratory protection is also important when working with aerosols or dust generated from urethane, the emphasis on skin absorption addresses the specific risk posed by direct contact with these chemicals.
