Safety & Health

Health Effects

BTC 824 quats are moderately toxic orally (LD₅₀ is between 50 and 500 mg/kg) and cause extreme skin and eye irritation at 25% active.

Packaging & Availability

Packaging Type
Standard Packaging

BTC 824 products are available in 55 gallon drums {425 lb (193 kg) for BTC 824; 400 lb (182 kg) for BTC 8248 and BTC 8249} and in bulk quantities.

Storage & Handling

Storage & Handling
  • Handle liquid BTC products with care; use away from sparks and open flame. Use in well ventilated area. Avoid contact with eyes, nose or prolonged skin contact. Gloves, protective clothing, safety goggles and face shield should be worn when handling BTC products. Wash thoroughly after handling material.
  • It is recommended that BTC 824 and BTC 8248 products be stored in sealed containers and kept in a cool, dry place. It is recommended that BTC 8249 be stored in sealed containers and kept in a dry place at a temperature of 60 - 90°F. If material is frozen it should be heated at 95 - 120°F and stirred to ensure it is homogeneous before use. BTC 8249 can freeze if stored at temperatures below 50°F.
  • Bulk Storage Information: BTC quaternaries can be stored in vessels of 316 stainless steel or fiberglass with a corrosion liner. Contact between quaternaries and anionic materials must be avoided. At use dilution, BTC quaternaries are non-corrosive to most plastics, natural rubber, stainless steel, monel metal, iron, brass, aluminum, lead and tin; however, BTC quaternaries as supplied, may be corrosive to the materials listed above.
  • Liquid BTC products should be stored between 60 - 90°F. An internal hairpin coil of 316 stainless steel with low pressure steam (under 50 psig) should be used if heating is required. Mild agitation is recommended while storing to maintain homogeneity. Pumps, pipes and transfer lines should be 316 stainless steel. Rubber hoses with Teflon cross-linked polyethylene with 316 S.S. fittings are recommended for loading and unloading.
Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
