The Control of Substances Hazardous to Health (COSHH) Regulations says you must protect against the risks from isocyanates.

You can find isocyanates in a number of construction products including polyurethane paints, coatings, foams, glues and flooring. Certain tasks, such as spraying and printing, can produce very high exposure to isocyanates.

Gas Detection

Gas detection equipment provides visual warnings for workers against the levels of isocyanates in the workplace and to provide evidence for employee occupational records.

Colorimetric detection or paper tape technology as it’s also known is the principle technology for monitoring isocyanates.

Direct reading, “passive” sampling badges are generally worn directly on the worker’s clothing, close to the breathing area. Air samples are representative of the 8 hour TWA and 15 minute short term exposure of each employee. As the target gas comes into contact with the inert paper tape, a colour change takes place. The colour change is representative of how much gas the worker has been exposed to.
