Reaktivit?t anzeigen
Direct Black 38 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases may form with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases form with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Incompatible with strong acids [NTP, 1992)].
Hazard
Confirmed carcinogen. Moderately toxic
by ingestion and inhalation. An eye irritant.
Health Hazard
ACUTE/CHRONIC HAZARDS: Direct Black 38 may be absorbed through the skin. When heated to decomposition it emits very toxic fumes of nitrogen oxides, disodium oxide and sulfur oxides.
Brandgefahr
Flash point data for Direct Black 38 are not available; however, Direct Black 38 is probably combustible.
Sicherheitsprofil
Confirmed carcinogen
with carcinogenic and tumorigenic data.
Moderately toxic by ingestion and
inhalation. An eye irritant. Mutation data
reported. When heated to decomposition it
emits very toxic fumes of NOx, Na2o, and
so2.
