Arsenic carcinogenic classification

Hygienists (ACGIH), International Agency for Research on Cancer (IARC), and World Health Organization (WHO) have established guidelines on exposure and classifications of the carcinogenicity of arsenic. 

ACGIH TLV TWA 0.01 mg/m Confirmed Human Carcinogen BEI 35 (As)/L inorganic arsenic and methylated metabolites in urine DFG MAK Human Carcinogen NIOSH REL CL 2 g(As)/mVl5M DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE Confirmed human carcinogen. Poison by ingestion. Moderately toxic by skin contact. When heated to decomposition it emits toxic fumes of arsenic. 

DOT CLASSIFICATION 6.1 Label Poison SAFETY PROFILE Confirmed human carcinogen. Poison by ingestion. When heated to decomposition it emits toxic fumes of arsenic. See also ARSENIC COMPOUNDS. 

NIOSH REL (Arsine) CL 2 ng(As)/mVl5M DOT CLASSIFICATION 2.3 Label Poison Gas, Flammable Gas SAFETY PROFILE Confirmed human carcinogen. Poison by inhalation. Human red blood cell, gastrointestinal system, central nervous system, and other systemic effects by inhalation. Flammable when exposed to flame. Moderately explosive when exposed to CI2, HNO3, (K + NH3), open flame, or powerful shock. Dangerous, more toxic than its oxidation product. When heated to decomposition it emits highly toxic fumes of arsenic. See also ARSENIC, ARSENIC COMPOUNDS, and HYDRIDES.
