Earlier in 2019, the HSE released their bulletin announcing that Mild Steel welding fumes was now classed as carcinogen. This put Mild steel welding into the same category as Stainless and Galv welding (just to name a few examples). The announcement didn’t come with any clear advice on control. The HSE have reacted to criticism…
This HSE slide show explains the importance of Tyndall lamp assessments in a spray paint application. A Tyndall lamp uses the sunlight effect to illuminate invisible particles that you cannot see under normal circumstances. The tyndall assessment is an important element of an LEV Through Examination and Test. The usefulness of a Tyndall lamp is…

This Research Report (RR1126) by HSE, published in 2018 looked at the factors that influence the effectiveness of in-cab air filtration systems throughout their operational lifecycle, including system design, in-service use, and maintenance. The research included developing a new scientific method to evaluate filtration system efficiency whilst a vehicle is being driven. The research found:…
HSE Research Report RR1146 published 2019 which sets out to measure emissions of particulates and volatile organic compounds from desktop 3D printers and to investigate the effectiveness of control measures to reduce these printer emissions. The research found that the heated filaments emitted large numbers of very small particles and volatile organic chemicals which could…
HSE sponsored Research Report RR1010 (2014) undertaken by HSL. Key Messages from this Report:- Two test methods for measuring the efficiency of integral on-gun welding fume extraction systems have been devised and assessed. As a result, Method 1 has been selected and is currently being developed by technical committee CEN/TC 121/SC 9/WG 4 (Testing and…

In February 2019 HSE announced that Welding Fume was to be considered a human carcinogen. This has had a major impact across a wide range of industries and employers. Questions are arising as to what elements of the welding ‘fume’ are implicated and what control responses would be appropriate. This Monograph is the original document…
In February 2019 HSE released a Press Note which advised of the new health warning status of welding fume. The main points made were:- New scientific evidence that exposure to all welding fume, including mild steel welding fume, can cause lung cancer. Also limited evidence linked to kidney cancer. Now a change in HSE enforcement…
