What PPE is required when working with isocyanates?

When working with isocyanates, especially in spraying or high-exposure tasks, proper PPE (Personal Protective Equipment) is crucial. At a minimum, you’ll want to make sure workers have:

• Respiratory protection – This usually means a full-face or half-face respirator with filters suitable for organic vapours and particulates (often an A2P3 or similar rating). In some cases, powered air respirators or air-fed hoods are needed.

• Gloves – Chemical-resistant gloves, like nitrile or butyl rubber. Standard disposable gloves often won’t cut it.

• Protective clothing – Coveralls or disposable suits that prevent skin contact. If spraying, you’ll want something that’s also resistant to permeation.

• Eye protection – If a full-face respirator isn’t used, safety goggles or face shields are essential.

It’s also important that PPE is correctly fitted, checked regularly, and replaced when damaged. And of course, PPE is the last line of defence — it should be used along with proper ventilation and process controls, not instead of them.
