Air & Water Reaktionen
Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water. -
Reaktivität 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. -
mögliche Exposition
Mutagen; Human Data. Direct black38 is an azo compound and is used to dye fabric, leather,cotton, cellulosic materials, and paper; these are then usedin consumer products. The chemical may be used by artists(CPSC, EPA). The FDA has indicated that although directblack 38 is identified in the literature as a hair-dye component, it is currently not used by the cosmetic industry. Inview of a health hazard alert issued in December 1980 byOSHA, which cautioned workers and employers of the carcinogenic effect of benzidine-derived direct black 38,new nonbenzidine direct black dyes have been developedand used successfully in commercial applications by thepaper and leather industry. These nonbenzidine dyes weredeveloped with the hope of replacing benzidine-based dyesthroughout industry. -
Erste Hilfe
Skin Contact: Flood all areas of the body thathave contacted the substance with water. Do not wait toremove contaminated clothing; do it under the water stream.Use soap to help assure removal. Isolate contaminatedclothing when removed to prevent contact by others. EyeContact: Remove any contact lenses at once. Flush eyeswell with copious quantities of water or normal saline for atleast 2030 min. Seek medical attention. Inhalation: Leavecontaminated area immediately; breathe fresh air. Properrespiratory protection must be supplied to any rescuers. Ifcoughing, difficult breathing or any other symptomsdevelop, seek medical attention at once, even if symptomsdevelop many hours after exposure. Ingestion: If convulsions are not present, give a glass or two of water or milk todilute the substance. Assure that the person’s airway isunobstructed and contact a hospital or poison center immediately for advice on whether or not to induce vomiting. -
Lager
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Store in a cool, dry place. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. -
