TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use special powder, dry sand. NO other agents. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Shortness of breath. Sore throat. Weakness. Symptoms may be delayed. See Notes.  Use local exhaust. Use breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection if powder.  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. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect the spilled substance into containers. If appropriate, moisten first to prevent dusting. Then store and dispose of according to local regulations.  Unbreakable packaging.
Put breakable packaging into closed unbreakable container.
Do not transport with food and feedstuffs. 
EC Classification
Symbol: T+; R: 49-25-26-36/37/38-43-48/23; S: 53-45; Note: E 
UN Classification
UN Hazard Class: 6.1; UN Subsidiary Risks: 4.1; UN Pack Group: II 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-61GTF3-II.
NFPA Code: H3; F1; R0. 
Separated from strong acids, bases, chlorinated solvents and food and feedstuffs. Store in an area without drain or sewer access. 

IMPORTANT DATA
Physical State; Appearance
GREY-TO-WHITE POWDER. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Reacts with strong acids and strong bases. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Mixtures with some chlorinated solvents, such as carbon tetrachloride and trichloroethylene are shock-sensitive. 

Occupational exposure limits
TLV: 0.002 mg/m³ as TWA; 0.01 mg/m³ as STEL; A1 (confirmed human carcinogen); (ACGIH 2004); notice of intended change (see Notes).
MAK: Carcinogen category: 1; Sensitization of respiratory tract and skin (SAH); (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 aerosol is irritating to the respiratory tract. Inhalation of dust or fume may cause chemical pneumonitis. Exposure could cause 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. Repeated or prolonged inhalation of of dust particles 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
Boiling point: >2500°C
Melting point: 1287°C
Density: 1.9 g/cm³
Solubility in water: none 
The substance is very toxic to aquatic organisms. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT take working clothes home.
Card has been partly updated in October 2005.
