EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation
Closed system and ventilation.
Fresh air, rest. Refer for medical attention.
Skin
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes
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.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. Chemical protection suit including self-contained breathing apparatus.
Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

BERYLLIUM CARBONATE ICSC: 1353
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE POWDER

CHEMICAL DANGERS:
The substance decomposes on heating above 200C producing beryllium oxide.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Be) 0.002 mg/m as TWA, 0.01 mg/m as STEL; A1 (confirmed human carcinogen); (ACGIH 2004).
MAK: sensitization of respiratory tract and skin (Sah); Carcinogen category: 1; (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 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The aerosol of this substanceis irritating to 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
Solubility in water: none
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
NOTES
Due to lack of specific data on this substance, the information included in this card was derived by analogy with other insoluble beryllium compounds. 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.
