Preservabalance <br /> MDec- 05 <br /> ENGINEERING CONTROLS : Use process enclosures , local exhaust ventilation , or other engineering controls as <br /> needed to control airborne levels below recommended limits . <br /> EYE PROTECTION : Safety goggles can be used where needed to avoid eye contact and for dusty environments . <br /> SKIN PROTECTION : Gloves and other skin protection are not normally required but can be used where needed to <br /> avoid prolonged contact or contact with open wounds or damaged skin . <br /> RESPIRATORY PROTECTION : If exposure limits are exceeded or if irritation is experienced, NIOSH approved <br /> respiratory protection should be worn . Ventilation and other forms of engineering controls are the preferred means <br /> for controlling chemical exposures . Respiratory protection may be needed for non- routine or emergency situations . <br /> 9 , PHYSICAL AND CHEMICAL PROPERTIES <br /> BOILING POINT : Not applicable <br /> BULK DENSITY : 320 — 480 kg/m' <br /> MELTING POINT : 815 ° C <br /> % VOLATILE : Negligible <br /> VAPOR PRESSURE : Negligible <br /> FLASH POINT: None <br /> % SOLUBILITY IN WATER: 9 .7% @ 20 °C, 34 .3 % @ 50 °C <br /> OCTANOL/WATER PARTITION COEFFICIENT: Not available <br /> pH : 8 . 3 (3 % solution) , 7 . 6 ( 10% solution ) <br /> APPEARANCE/ODOR: White odorless powder. <br /> 101 STABILITY AND REACTIVITY DATA <br /> STABILITY/INCOMPATIBILITY : Stable . Avoid zirconium , strong acids , strong reducing agents and metallic <br /> salts . <br /> HAZARDOUS REACTIONS/DECOMPOSITION PRODUCTS : Reaction with strong reducing agents such as <br /> metal hydrides or alkali metals will generate flammable hydrogen gas . Thermal decomposition, which can occur at <br /> extremely high temperatures , produces oxides of carbon and nitrogen . <br /> 11 TOXICOLOGICAL INFORMATION <br /> PRODUCT HEALTH HAZARD INFORMATION <br /> INGESTION : Swallowing small amounts ( less than I teaspoon) will not harm healthy adults . Swallowing large <br /> amounts will cause severe gastrointestinal irritation with nausea, vomiting and diarrhea . Delayed skin rash and rash <br /> on the mucous membranes may occur. Kidney injury may also occur . <br /> SKIN : Not expected to cause skin irritation . Disodium octaborate, tetrahydrate is not absorbed through the intact <br /> skin but can be absorbed in harmful amounts through open wounds and damaged skin . <br /> EYE : May cause mild irritation . Corneal injury is not expected . <br /> INHALATION : Inhalation of dust may cause respiratory irritation with coughing, nasal irritation, nose bleeds or <br /> difficulty breathing . <br /> CHRONIC EFFECTS : Disodium Octaborate , Tetrahydrate is converted to Boric Acid in biological systems . <br /> Information on the chronic effects of exposure to this product is based on studies with Boric Acid and other borates . <br /> Chronic absorption of borates may result in weight loss , mild diarrhea, skin rash , loss of hair and anemia. Human <br /> epidemiological studies do not show any increase in respiratory disease in workers exposed to borates . <br /> Page 3 of S <br /> i <br /> I <br /> I <br />
