WHAT ARE HAZARDOUS SUBSTANCES?

Are you unsure whether hazardous substances are produced in your workplace? Hazardous substances are substances and mixtures that have one or more "hazardous properties." Hazardous properties include, for example, being toxic, corrosive, carcinogenic, highly flammable, or hazardous to the environment.

Substances with prescribed occupational exposure limits and substances that endanger health due to their chemical properties are also considered hazardous substances.

Hazardous substances in the welding shop include zinc oxides formed during welding work with zinc sheets and nitrogen oxides formed at the edge of an oxyacetylene flame.

HIVENT offers a wide range of different extraction systems to keep the concentration of hazardous substances in the air as low as possible. These effectively filter hazardous substances from the air and ensure healthy occupational hygiene.

HAZARDOUS SUBSTANCES DURING WELDING WORKS

Welding, thermal cutting, and spray soldering produce welding fumes that are hazardous to health. The particles contained in welding fume are hazardous to humans. These particles can belong to dust fraction A. In this case, the welding fume particles are alveolar. Class E welding fume particles are inhalable. 95% of the hazardous particulate matter originates from the filler materials used during welding operations. These are generally metal oxides released during welding.

In addition to particulates, welding fumes can contain hazardous gaseous substances produced during machining processes such as gas welding and flame spraying.

Ozone: This hazardous substance is primarily produced when welding materials that reflect radiation. These include aluminum sheets and chrome-nickel steels (MIG). Ozone exposure is particularly severe during low-fume welding (TIG). This hazardous substance is a carcinogen listed on the hazardous materials list.

Phosgene: This hazardous substance is produced during welding operations at temperatures above 300°C. The toxic gases released during this process cause a caustic reaction in mucous membranes and skin.

Carbon monoxide: This hazardous substance is produced during mixed gas shielded welding or oxy-acetylene welding due to thermal decomposition.

Nitrogen oxide: This hazardous substance is formed near a flame or arc. Breathing nitrogen oxide can damage the lungs.

HIVENT offers a suitable fume extraction solution for extracting welding fume particles and gases. HIVENT welding fume filters effectively extract particles at the source, ensuring a safe and healthy working environment. With HIVENT, you comply with the specified limit values.
