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…

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…
