Is welding smoke carcinogenic? International cancer researchers now say a clear ‘yes’!
International cancer researchers determined that welding smoke is carcinogenic, in a recently published article. According to the cancer research agency of the World Health Organization, welding smoke has so far only been classified as possibly carcinogenic. With the new classification, the scientists adapted the estimation of the risks posed by welding smoke on the basis of new findings from several studies.
40 years of KEMPER – the interview: “In former times, welding fumes were regarded as healthy to some extent”
With a gut feeling, courage and of course a set of reliable figures as a basis, in 1977 Gerd Kemper set out on a personal crusade: clean air at the workplace while welding.

Limit values for welding fumes: Let’s count the particles!
Are today’s limit values for welding fumes still relevant in their current form? Science and the industrial sector have doubts. KEMPER GmbH argues in favour of measuring the number of particles when evaluating welding fumes concentration. The true health hazard for employees is before the limit is reached – an essay by Björn Kemper.
