  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use fine water spray, dry powder, dry sand. NO other agents.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed. See Notes.  Use closed system.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Wear protective gloves when administering first aid. 
Eyes   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. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

BERYLLIUM ICSC: 0226
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
GREY SOLID IN VARIOUS FORMS. 

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. On combustion, forms toxic fumes including beryllium oxide (see ICSC 1325). 

Formula: Be
Atomic mass: 9.0
Boiling point: >2400°C
Melting point: 1287°C
Density: 1.9 g/cm³
Solubility in water: insoluble 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the respiratory tract. Inhalation of dust or fume may cause chemical pneumonitis. The effects may be delayed. Medical observation is indicated. Exposure could cause death. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Sensitization to the substance, through repeated or prolonged inhalation or skin contact, may result in serious granulomatous lung disease (chronic beryllium disease). This substance is carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (inhalable fraction): 0.00005 mg/m3, as TWA; A1 (confirmed human carcinogen); (skin); (SEN).
MAK: sensitization of respiratory tract and skin (SAH); carcinogen category: 1.
EU-OEL: (inhalable fraction): 0.0002 mg/m3 as TWA; (skin and respiratory sensitizer); (see Notes) 

ENVIRONMENT
The substance may cause long-term effects in the aquatic environment. 

NOTES
The substance is combustible but no flash point is available in literature.
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.
Isolate contaminated clothing by sealing in a bag or other container.
An EU-OEL of 0.0006 mg/m3 is allowed until 11 July 2026.
