Occupational exposure limit
The occupational exposure limit is the maximum allowable concentration of a substance in the air at the workplace. It must be met during welding processes through extraction and ventilation.
Physical-Chemical Mechanism of Action
The occupational exposure limit (OEL) is the maximum concentration of a substance in the air that may be harmful to health over a certain period. This value is set by legislation and standards.
Metallurgical Relevance & Risks in Welding
During welding processes, toxic substances such as carbon monoxide or sulfur dioxide can be released. Exceeding the OEL can lead to health problems, such as respiratory diseases or poisoning.
Workshop Practice & Instructions
To meet the occupational exposure limit during welding processes, suitable extraction and ventilation measures must be taken. This includes installing ventilation systems that reduce the concentration of substances in the air. The concentration should be measured and monitored regularly.
