In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  •INHALATION Cough. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Vomiting. Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment.

International Chemical Safety Cards ZINC CHROMATE ICSC: 0811 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: YELLOW CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: OCCUPATIONAL EXPOSURE LIMITS: TLV (as Cr): 0.01 mg/m3 (as TWA) A1 (ACGIH 1999). MAK: class III.1.Sh (1999) ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed . EFFECTS OF SHORT-TERM EXPOSURE: Inhalation of dust may cause irritation. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation exposure may cause asthma. Repeated or prolonged exposure may cause nasal ulceration. This substance is carcinogenic to humans. PHYSICAL PROPERTIES Melting point: 316°C Density: 3.4 g/cm3 Solubility in water: none ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. N O T E S The term zinc chromate is also used to refer to a wide range of commercial zinc and zinc potassium chromates. It has several CAS numbers. Depending on the degree of exposure, periodic medical examination is indicated. Pigment Yellow 36 and Buttercup Yellow are trade names. Do NOT take working clothes home.
