International Chemical Safety Cards BERYLLIUM NITRATE ICSC: 1352 BeN2O6 / Be(NO3)2 Molecular mass: 133.0 ICSC #    1352 CAS #     13597-99-4 RTECS # DS3675000 UN #        2464 EC #         004-002-00-2 April 12, 2000 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Cough. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes). Closed system and ventilation. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Pain. Face shield or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Wash hands before eating. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Chemical protection suit including self-contained breathing apparatus. Separated from food and feedstuffs . Well closed. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

International Chemical Safety Cards BERYLLIUM NITRATE ICSC: 1352 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE TO YELLOW SOLID IN VARIOUS FORMS PHYSICAL DANGERS: CHEMICAL DANGERS: Attacks many metals in presence of water. OCCUPATIONAL EXPOSURE LIMITS: TLV: (as Be) 0.002 mg/m³ as TWA, 0.01 mg/m³ as STEL; A1 (confirmed human carcinogen); (ACGIH 2004). MAK: sensitization of respiratory tract and skin (Sah); Carcinogen category: 1; (DFG 2004). 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: The substance is irritating to the eyes , the skin and the respiratory tract . Inhalation of dust or fumes may cause chemical pneumonitis. Exposure may result in death. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. Lungs may be affected by repeated or prolonged exposure , resulting in chronic beryllium disease (cough, weight loss, weakness) . This substance is carcinogenic to humans. PHYSICAL PROPERTIES Boiling point (decomposes): 100°C Melting point: 60°C Density: 1.56 g/cm3 Solubility in water: very good ENVIRONMENTAL DATA The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. N O T E S The symptoms of acute pneumonitis following a massive short-term exposure do not become manifest until 3 days. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home. Card has been partly updated in April 2005.
