In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION 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.

International Chemical Safety Cards SODIUM BORATE, DECAHYDRATE ICSC: 0567 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE CRYSTALS OR CRYSTALLINE POWDER. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance is a weak base. OCCUPATIONAL EXPOSURE LIMITS: TLV: 5 mg/m3 (ACGIH 1996). OSHA PEL: none NIOSH REL: TWA 5 mg/m3 NIOSH IDLH: No data 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. PHYSICAL PROPERTIES Boiling point: 320°C Melting point: 75°C Relative density (water = 1): 1.7 Solubility in water, g/100 ml at 20°C: 5.1 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Jaikin, Pyrobor, Three Elephant, V-Bor are trade names. ADDITIONAL INFORMATION ICSC: 0567 SODIUM BORATE, DECAHYDRATE (C) IPCS, CEC, 1994
