EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Sodium mercaptobenzothiazole will partition into aq compartments. Being nonvolatile, it will not partition to the atmosphere.

Below pH 7 sodium mercaptobenzothiazole will be protonated to form insoluble mercaptobenzothiazole. If iron is present sodium mercaptobenzothiazole will be reduced to benzothiazole.

In aqueous solution sodium mercaptobenzothiazole is not oxidized even @ temp of 100 °C, nor is it readily hydrolyzed.

In a weak alkaline or neutral soln the mercaptobenzothiazole anion can readily complex with various metal ions, such as Cu+2 or Zn+2, and form insoluble relatively undissociable salts.

Mercaptobenzothiazole compounds enter the environment through plant effluents and emissions associated with their manufacture, use, and end product processing and through the degradation and wear of end products, such as tire dust. /Mercaptobenzothiazole/

Substantial releases will occur when mercaptobenzothiazole leach from the est 12 million lb of vulcanization accelerators that are deposited as tire dust along the nation's highways. Releases will asooccur as a result of disposal of waste radiator coolants from automobiles and industrial cooling systems.

It is unlikely that sodium mercaptobenzothiazole will bioconcentrate, since substitution of the mercapto group on benzothiazole should reduce its partition coefficient ... The fact that sodium mercaptobenzothiazole is a salt will even further reduce the partition coefficient and thus its tendency to bioaccumulate.

Daily oral admin to two hybrid strains of mice of 100 mg/kg of mercaptobenzothiazole in 0.5% gelatin failed to cause a significant increase in tumors after 18 months of treatment. /Mercaptobenzothiazole/

A drop in blood glucose in rabbits 5 hr after ip injection of mercaptobenzothiazole at a dose of 100 mg/kg was observed.

Male mice treated daily for one week with ip injections of mercaptobenzothiazole at one-fourth and one-eight the LD50 (110 and 55 mg/kg, respectively) showed no signs of overt toxicity after one week. Microscopic exam of various tissues, however, revealed serious damage to liver of mice receiving the 110 mg/kg dose. Tissues from mice receiving the 55 mg/kg dose were not examined microscopically. /Mercaptobenzothiazole/

Consumers are expected to be exposed to sodium mercaptobenzothiazole through its use as: a corrosion inhibitor in automobile antifreeze solution, a thermal stabilizer in silicon fluids, a preservative in latex paint and on wood, and a component of agricultural pesticides.

Used to make rubber accelerators, and as a fungicide, a preservative for latex paint and wood, a metal chelator, and a thermal stabilizer (methyl methacrylate copolymers, acrylonitrile polymers, polyester fibers, anion exchange resins, polyoxyphenylene, and silicon fluids); Also used in electroplating (silver, nickel, and cobalt), to separate sulfide ore from copper ore, for dyeing textiles, in transmission fluids, and to prevent discoloration of freeze dried bananas; Uses of 50% aqueous solution include as a corrosion inhibitor for nonferrous metals in antifreeze and coolants and in paper mill systems; [HSDB] Used as a biocide in metalworking fluids and paper manufacturing; [Reference #1]
