Hazard statements

Categories Not classified

Signal word

WARNING! This product as shipped is not classified as a combustible dust; however, a combustible concentration of dust may occur if fines are suspended in air (e.g. from cutting or sanding the Coroplast® sheets). WARNING! Carbon black is classified as a 2B Carcinogen by IARC (possibly carcinogenic to humans) when in a respirable form. Occupational Exposure Limit in the United States and Canada is 3.5 mg/kg TWA (8-hour time weighted average).

Hazard pictograms

There is no pictogram for a combustible dust hazard Rough edges of Coroplast® sheets could result in minor cuts to hands. Appropriate gloves should be worn to prevent cuts and/or scraps. Avoid contact with strong oxidizing agents. When working with the Coroplast® sheets at temperatures above the melting point, the material may begin to decompose producing fumes that can contain carbon dioxide, carbon monoxide, ketones, acrolein, formaldehyde, aldehydes, oxides of nitrogen and other unidentified organic compounds that come from the breakdown of the materials used to make the sheets. Adequate ventilation should be provided to minimize exposures to vapors. When cutting, shaping or modifying Coroplast® sheets, other hazards may exist.

Potential health effects

Eyes: Dust from cutting may result and mechanically irritate the eyes; if using elevated temperatures, vapors may irritate eyes Skin: Cuts or scraps referenced above; if using elevated temperatures to soften the Coroplast® sheets, exposure to molten resin may cause thermal burns Ingestion: Dust or debris from cutting may irritate the throat, mouth and stomach Inhalation: Inhalation of fine dust, from cutting or sanding, may cause irritation of the respiratory system. Inhalation of vapors from use of elevated temperatures may also cause irritation of the respiratory system. Chronic: Inhalation of fine dust is a potential carcinogen situation from respirable particles of carbon black.
