TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible.
NO open flames.
Special powder, dry sand, NO other agents.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

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).
Local exhaust. 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.
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 take to a doctor.
•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

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 forming flammable/explosive gas (hydrogen - see ICSC0001) . Forms shock sensitive mixtures with some chlorinated solvents, such as carbon tetrachloride and trichloroethylene.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.002 mg/m3 as TWA, 0.01 mg/m3 as STEL; A1 (confirmed human carcinogen); (ACGIH 2004). Intended change 0.00002 mg/m3
Skin, Inhal.
SEN (ACGIH 2005).
MAK: sensitization of respiratory tract and skin (Sah);
Carcinogen category: 1;
(DFG 2004).
OSHA PEL: TWA 0.002 mg/m3 C 0.005 mg/m3 0.025 mg/m3 30-minute maximum peak
NIOSH REL: Ca Not to exceed 0.0005 mg/m3 See Appendix A
NIOSH IDLH: Ca 4 mg/m3 (as Be) See: IDLH INDEX


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 respiratory tract . Inhalation of dust or fumes may cause chemical pneumonitis. Exposure may result in 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. Lungs may be affected by repeated or prolonged exposure to dust particles , resulting in chronic beryllium disease (cough, weight loss, weakness). This substance is carcinogenic to humans.

PHYSICAL
PROPERTIES

Boiling point: above 2500°C
Melting point: 1287°C
Density: 1.9

Solubility in water:
none

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms.

N O T E S

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. See sections Occupational Exposure Limits, Emergency Response.
Transport Emergency Card: TEC (R)-61GTF3-II

NFPA Code: H3; F1; R0
Card has been partially updated in January 2008: see Storage.
