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).
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.

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 Be) 0.002 mg/m3 as TWA, 0.01 mg/m3 as STEL; A1 (confirmed human carcinogen); Intended change : 0.00005 mg/m3 as TWA; 0.0002 mg/m3 as STEL; (skin); SEN; A1 (confirmed human carcinogen); (ACGIH 2008).
MAK: sensitization of respiratory tract and skin (Sah);
Carcinogen category: 1;
(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 of this substance is irritating to 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 suggested. Do NOT take working clothes home. Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
Transport Emergency Card: TEC (R)-61GT5-II
Card has been partially updated in February 2009: see Occupational Exposure Limits.
