The Health and Safety Executive for Northern Ireland (HSENI) has reiterated its call for construction employers to train staff handling diisocyanate-based products, widely used in paints, foams, sealants, adhesives and varnishes. Exposure primarily occurs through inhalation or skin contact and can cause occupational asthma and allergic contact dermatitis.

As part of its Workplace Health Campaign, HSENI highlights that since 24 August 2023, all professional and industrial users of products containing diisocyanates at concentrations of 0.1 per cent or more must complete specialist training. This applies to both online and in-person courses, in line with EU-derived regulations still effective in Northern Ireland.

Ronan Magee, head of HSENI’s market compliance chemicals team, emphasised the health risks posed by diisocyanates across a broad range of manufacturing and construction products. Employers are advised to consult safety data sheets to identify affected products and ensure all relevant staff have completed the required training.

HSENI warns that non-compliance by employers or self-employed workers could result in enforcement action. The agency notes that proactive risk management not only protects workers but also helps reduce the long-term burden on the health service and wider economy.

Businesses operating on construction sites are being encouraged to review training protocols and chemical handling procedures immediately to meet regulatory obligations and safeguard workforce health.
