SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.|Personnel protection: Do not handle broken packages unless wearing appropriate personal protective equipment. Was away any material which may have contacted the body with copious amounts of water or soap and water. Approach fire with caution.|Personnel protection: Wear appropriate chemical protective gloves, boots, and goggles.

moderately toxic

/ACCIDENTAL POISONINGS/ Several fresh and brackish water organisms of Germany were harmed by concentration of sodium perborate, boric acid and boron greater than 250, 5000 or 2500 mg/L, respectively, when discharged into water with sewage.

Sodium borate and boric acid are used in various cosmetic products, including make-up, skin and hair care preparations, deodorants, moisturizing creams, breath fresheners, and shaving creams; concentrations may be up to 5%(1).

MEDICATION (VET): ...Has been used extensively for topical treatment of stomatitis, glossitis, and gingivitis.|MEDICATION (VET): Has primarily been used as antiseptic and deodorant intrauterine in cows after manual removal of retained placentas; useful in dusting powders on infected wounds and in antiseptic irrigation (1-2%) of foul smelling wounds

... It should be used sparingly since repeated applications to mucous membranes may be irritating.|Prevent swallowing of solution.

The fatal dose of boric acid, sodium borate, or sodium perborate is 0.1-0.5 g/kg.

A group of water-soluble vitamins, some of which are COENZYMES. (See all compounds classified as Vitamin B Complex.)

Excretion occurs primarily in the urine.

Maintain an open airway and assist ventilation if nescessary. treat coma, seizures, hypotension, and renal failure if they occur. There is no specific antidote. Administer activated charcoal (although boric acid is not well absorbed). Consider gastric lavage for large ingestions. /Boric acid, Borates, and Boron/|Hemodialysis is effective and is indicated after massive ingestions and for supportive care of renal failure. Peritoneal dialysishas not proved effective in enhancing elimination in infants. /Boric acid, Borates, and Boron/|In acute poisonings, if a large amount has been ingested and the patient is seen within one hour of exposure, gastrointestinal decontamination should be considered ... .It is important to keep in mind that vomiting and diarrhea are common, and severe poisoning may be associated with seizures. Therefore induction of emesis by syrup of ipecac is probably contraindicated in these exposures. Catharsis is not indicated if diarrhea is present. /Boric acid and Borates/|If ingestion of borate has been massive (several grams), or has extended over several days, administer intravenous glucose and electrolyte solutions to sustain urinary excretion of borate. Monitor fluid balance and serum electrolytes (including bicarbonate capacity ) regularly. Monitor cardiac status by ECG. Test the urine for proteins and cells to detect renal injury, and monitor serum concentration of borate. Metabolic acidosis may be treated with sodium bicarbonate. If shock develops, it may be necessary to infuse plasma or whole blood. Administer oxygen continuously. If oliguria (less than 25 to 30 mL urine per hour) occurs, intravenous fluids must be slowed or stopped to avoid overloading the circulation. Such patients should be referred to a center capable of providing intensive care for critically ill patients. /Boric acid and Borates/|For more Antidote and Emergency Treatment (Complete) data for SODIUM PERBORATE (7 total), please visit the HSDB record page.

An observed higher prevalence in the younger age groups can be explained by the selection of those with skin diseases for work away from the cleaning department. Many persons developed their disease shortly after employment began, which indicated that most conditions were irritant diseases. This was confirmed by diagnosis: 75% of the conditions were irritant dermatitis (formaldehyde, glutaraldehyde, chloramine, nickel, rubber), 21% were allergic contact dermatitis (detergents, alkaline substances, acids, sodium perborate, hypochlorite and hypobromite compounds), and 4% were monilia of the finger webs.|/OTHER TOXICITY INFORMATION/ The fatal dose of boric acid, sodium borate, or sodium perborate is 0.1-0.5 g/kg.

All other basic organic chemical manufacturing|Perboric acid (HBO(O2)), sodium salt (1:1): ACTIVE|Sodium perborates are persalts that are hydrolytically unstable because they contain characteristic boron-oxygen-oxygen bonds that react with water to form hydrogen peroxide and stable sodium metaborate (NaBO2.nH2O). This hydrolysis reaction is the basis of the use of perborates as bleaches in detergents at high (70-100 °C) temperature. At lower washing temperatures (25-70 °C), activators are needed; these react with peroxide to give peracids, which are stronger oxidants and give bleaching effects at lower temperatures.

An automated fluorometric method is described for measuring boron in compounds such as boric acid, borax, & sodium perborate in water & sewage effluents.
