WorkSafe Victoria has issued a fresh warning to businesses using paints that contain isocyanates—particularly in industries like automotive, construction, and metal fabrication. The reminder comes after multiple sites were found spray painting with inadequate or non-existent risk controls.
Isocyanates are hazardous substances commonly found in the hardener component of two-pack paints. When sprayed, they produce a fine mist that can be inhaled or absorbed through the skin, leading to severe health outcomes such as:

REMEMBER: A SWMS is legally required for any high-risk construction work involving hazardous substances like isocyanates.
