HSE Updates Guidance on Isocyanates: What UK Spray Professionals Need to Know

The Health and Safety Executive (HSE) has recently reinforced its position on the safe use of isocyanates in the workplace, placing renewed focus on training, awareness, and proper control measures across industries that rely on spray-applied coatings.

For UK spray professionals - particularly those working with 2K products in kitchens, furniture, and uPVC — this is an important development that cannot be ignored.

What Are Isocyanates and Why Are They Under Scrutiny?

Isocyanates are a key component in many two-pack (2K) paints and coatings, widely used for their durability and high-quality finish. However, they are also a leading cause of **occupational asthma** in the UK.

Exposure typically occurs through:

• Spray mist inhalation
• Poor ventilation in enclosed spaces
• Inadequate or incorrect PPE use

Because of these risks, the HSE continues to tighten guidance around how these products should be handled.

What Has Changed?

The latest HSE update places stronger emphasis on competency and training, aligning with wider industry changes already being seen across Europe.

Key points include:

• Mandatory training expectations for anyone working with isocyanate-containing products
• Greater focus on employer responsibility to ensure safe systems of work
• Increased attention on spray application, where exposure risk is highest
• Reinforcement of the need for appropriate respiratory protective equipment (RPE)

While some of these measures have been discussed previously, the HSE is now making it clear that enforcement and accountability are increasing.

 What This Means for Spray Businesses

For many UKSA members, this isn’t new information - but it does signal a shift towards stricter compliance and higher expectations across the industry.

Spray businesses should now be actively reviewing:

• Whether all operatives have up-to-date training
• The type and condition of RPE being used (air-fed vs mask systems)
• Extraction and ventilation setups
• Risk assessments and COSHH documentation

Those who are already operating professionally will likely find they are compliant - but those cutting corners may find themselves exposed to enforcement action.

Raising Standards Across the Industry

At UKSA, raising standards and professionalism within the spray finishing industry is a core priority. Updates like this highlight exactly why that matters.

As spraying continues to grow in popularity, particularly in sectors like kitchen respraying and uPVC coatings, it’s essential that safety standards grow with it.

This isn’t just about compliance - it’s about:

• Protecting your health and your team
• Building trust with customers
• Positioning spraying as a professional, respected trade

Looking Ahead

The direction of travel is clear: more regulation, more accountability, and a stronger focus on training.

For spray professionals, staying informed and operating to best practice is no longer optional - it’s essential.

UKSA will continue to keep members updated on key developments and provide guidance to help businesses stay compliant, safe, and competitive.
