Is carbon raiser a dangerous material

Users want to know if carbon raiser is a hazardous material. This question needs to be addressed in detail based on its composition, use, and form. Common carbon raisers are mainly used in the foundry and smelting industries as a material to increase carbon content. Most carbon raisers contain elementally stable materials such as graphite, calcined petroleum coke, and calcined coal, which are not flammable or explosive and are generally considered non-hazardous. For example, a pile of black granules in a smelter is not subject to the same strict management as flammable and explosive materials.

If you carefully observe the actual use of carbon raisers in industrial production, and see chartered trucks transporting bulk raw materials back and forth in the workshop, with workers handling them with bare hands without protective equipment, this suggests that the company is not classifying the material as a hazardous chemical. A review of common industrial product transportation records will show that the shipping company lists the vehicles transporting carbon raisers to the steel mill as "ordinary goods" on the road transport manifest, indicating that it falls under routine management.

Many commercially available 90% C fixed carbon recarburizers and graphitized coal recarburizers, according to the latest revised version of the National Hazardous Chemicals List, do not include these items in the carbon carrier category. Some chemical reagent websites list the LD50 (median lethal dose in rats) of their products as exceeding 200 mg/kg, far exceeding the threshold for hazardous substances, indirectly supporting the claim of no toxicity risk. It should be noted that for high-sulfur or specially treated gasified coal-to-liquid composite recarburizing media, further testing based on the specific material's corrosiveness or chemical activity is necessary.
