EXPOSURE
PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!

 •INHALATION Cough. Shortness of breath. Sore throat. Nose bleeds.
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated.
 •SKIN Dry skin. Redness. Pain.
Protective gloves.
First rinse with plenty of water, then remove contaminated clothes and rinse again.
 •EYES Redness. Pain.
Safety goggles, 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 Abdominal pain. Diarrhoea. Headache. Nausea. Vomiting. Weakness. Convulsions.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles).
Separated from acids.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR CRYSTALLINE POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: Borate compounds, inorganic 2 mg/m³ as TWA; 6 mg/m³ as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2005).
MAK not established.
OSHA PEL: none
NIOSH REL: TWA 5 mg/m3
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation 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 substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, kidneys and liver, when ingested. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
