New study: Ultrafine dust is a very common cause of cardiovascular diseases

Ultrafine dust leads to more cardiovascular diseases than acute heart attacks, cardiac insufficiency or cardiac arrhythmia – that’s the result of a new study. Welders are particularly affected. Most of the particles that can be found in welding fumes are … >> more

After the transitional period for the General Dust Exposure Level: for health-based occupational safety

Die TRGS 504 konkretisiert bestehende Verbandsvorgaben für den Umgang mit A-Staub und E-Staub auf einer verbindlicheren Rechtsebene.

In 2014, legislators in Germany lowered the General Dust Exposure Level by more than 60 percent. Under certain conditions, factories were able to continue operating at the old limit of 3 mg/m³. This transitional period ended at the turn of the year. This has repeatedly sparked many discussions amongst those affected, but above all it has created uncertainty. This period is finally over – with a plea for health-based occupational safety in each country.

How do ultrafine welding fume particles get into the body and what effects do they have?

Welding smoke carcinogenic? International researchers say "yes".

During welding, ultrafine particles are created which are breathed in or swallowed by welders. The smallest particles often cause the greatest damage. Yet, how exactly do these ultrafine particles affect the welder? And what kind of defense mechanism does the … >> more

Milk against welding fumes: not much more than an old wives’ tale

A daily ration of milk against welding fumes: This used to be the be-all and end-all of occupational safety. Yet, the legend about the protective effect of milk against health damage caused by welding fumes is partially still persistent today. … >> more

Hazardous substances in welding fumes: How they affect the human body

Gefahrstoffe im Schweißrauch

Welding fumes affect the lungs and are toxic or carcinogenic. The health consequences for the welder depend mainly on the composition of welding fumes. Science differentiates between three effects. The hazardous substances in welding fumes created during welding are formed … >> more

Thermal cutting: which hazardous substances are created

Thermal cutting generates harmful substances which are hazardous to health. A range of parameters influence the emission of harmful substances – and thus the potential for damage to health.

Welding fumes explained in brief: Why an extraction system is so important

Every metal processor should know these days that welding fumes are harmful.  Yet, one question gets asked over and over again: What are welding fumes exactly? Just looking at the composition gives an indication of what hazards are behind welding … >> more

Nitrous gases in welding fumes What dangers are faced when welding

nitrous gases in welding processes

Nitrous gases are often responsible for acute poisoning when welding. They occur during gas welding and arc welding processes. Due to current occupational medicine findings, the occupational exposure limits for nitrous gases were significantly lowered in May 2016. The term … >> more

Is welding smoke carcinogenic? International cancer researchers now say a clear ‘yes’!

Welding smoke carcinogenic? International researchers say "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.

Laser welding: automated, but hazardous for employees nonetheless

Auch beim Laserschweißen entsteht Schweißrauch.

Are there definitely risks from welding fumes, if a robot is doing the welding? Many welders ask this question when laser welding. The almost completely automated welding process mainly hides hazards if it is used with additives. A welding fume … >> more
