Occupational Exposure Limit for Welding Fumes
The occupational exposure limit for welding fume is the legally set maximum value of hazardous substances in the air during welding without causing health damage. It is checked by measurements.
Physical-Chemical Mechanism of Action
The occupational exposure limit (OEL) for welding fume indicates how high the concentration of hazardous substances in the air during welding may be without causing health problems. These limits take into account the long-term effects of hazardous substances on people.
Metallurgical Relevance & Risks in Welding
Exceeding the OEL for welding fume can lead to health problems, such as respiratory diseases or allergies. Furthermore, a high concentration of substances can affect the productivity and well-being of workers.
Workshop Practice & Instructions
To comply with the OEL for welding fume, regular air samples must be taken. These samples should be taken at least every 4 hours and be performed by qualified personnel. If an exceedance of the limit is detected, measures such as improving ventilation or using protective masks must be taken.
