WHAT ARE HAZARDOUS SUBSTANCES?
Are you not sure whether hazardous substances occur in your workplace? Hazardous substances are substances and mixtures with one or more "hazardous properties". Hazardous properties are, for example, toxic, corrosive, carcinogenic, highly flammable or dangerous for 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 plates and nitrogen oxides formed at the edge of an oxy-acetylene 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. Welding, thermal cutting and spray soldering produce welding fumes that are hazardous to health. The welding fume particles contained in them are dangerous for humans. They may belong to dust fraction A. In this case the welding fume particles are alveoli. Welding fume particles of class E can be inhaled. 95 % of particulate hazardous substances are formed from filler materials during welding work. These are usually metal oxides during welding work. In addition to particles, welding fumes may contain gaseous hazardous substances. These are produced during processing processes such as gas welding and flame spraying.
Ozone: This hazardous substance is mainly produced when radiation-reflecting materials are welded. These include aluminium sheets and chromium-nickel steels (MIG). Ozone exposure is particularly severe in low fume welding (TIG). The hazardous substance is one of the carcinogenic substances on the list of dangerous substances.
Phosgene: The hazardous substance is produced during welding work at temperatures above 300 °C. The toxic gases released during this process cause caustic reactions on the mucous membranes and skin.
Carbon monoxide: This hazardous substance is produced during gas shielded welding with gas mixture or oxy-acetylene welding due to thermal decomposition.
Nitrogen oxide: This hazardous substance is formed at the edge of a flame or arc. Inhalation of nitrous oxide damages the lungs.
HIVENT offers a suitable suction solution for the absorption of welding fume particles. HIVENT welding fume filters effectively extract particles at the weld and ensure a safe and healthy working environment. With HIVENT you comply with the specified limit values.
