International Chemical Safety Cards BERYLLIUM SULFATE ICSC: 1351 BeSO4 Molecular mass: 105.1 ICSC #    1351 CAS #     13510-49-1 RTECS # DS4800000 UN #        1566 EC #         004-002-00-2 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. 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 and then wash skin with water and soap.  •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 SULFATE ICSC: 1351 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating over 550-600°C producing sulfur oxides OCCUPATIONAL EXPOSURE LIMITS: TLV (as (TWA) ): 0.002 mg/m3 A1 (ACGIH 1999). MAK: class 2 (1999) OSHA PEL: TWA 0.002 mg/m3 (as Be) C 0.005 mg/m3 (as Be) 0.025 mg/m3 (as Be) [30-minute maximum peak] NIOSH REL: Ca Not to exceed 0.0005 mg/m3 (as Be) See Appendix A NIOSH IDLH: Potential occupational carcinogen 4 mg/m3 (as Be) 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 aerosol of this substance irritates the eyes, the skin and the respiratory tract. Inhalation of dust or fumes may cause chemical pneumonitis. The effects may be delayed. Medical observation is indicated. Exposure may result in death. 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 Melting point (decomposes): 550°C Density: 2.44 g/cm3 Solubility in water: see Notes 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 substance converts to soluble form in water. 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 indicated. Do NOT take working clothes home. Transport Emergency Card: TEC (R)-61G64b ADDITIONAL INFORMATION ICSC: 1351 BERYLLIUM SULFATE (C) IPCS, CEC, 2002
