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, 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.  Use closed system or 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.  Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes above 550-600°C . This produces sulfur oxides. 

Occupational exposure limits
TLV (as Be): 0.002 mg/m³ as TWA; 0.01 mg/m³ as STEL; A1 (confirmed human carcinogen); (ACGIH 2008); notice of intended change (see Notes).
MAK: Carcinogen category: 1; Sensitization of respiratory tract and skin (SAH); (DFG 2008). 

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 is irritating to the eyes, skin and respiratory tract. Inhalation of dust or fume may cause chemical pneumonitis. The effects may be delayed. Medical observation is indicated. Exposure could cause death. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause effects on the lungs. This may result in chronic beryllium disease (cough; weight loss; weakness). This substance is carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 550°C
Density: 2.44 g/cm³
Solubility in water: see Notes 
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. 

NOTES
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 suggested.
Do NOT take working clothes home.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
TLV Intended change: 0.00005 mg/m³ as TWA; 0.0002 mg/m³ as STEL; (skin); SEN; A1 (confirmed human carcinogen); (ACGIH 2008).
Card has been partially updated in February 2009: see Occupational Exposure Limits.
