Storage & Handling

Storage & Handling
  • Normal safety precautions (e.g., gloves and safety goggles) should be employed when handling TOXIMUL 8320. Contact with eyes, nose or prolonged contact with skin should be avoided. Wash thoroughly after handling TOXIMUL 8320. See SDS for more information.
  • Non-Bulk Storage Recommendations: TOXIMUL 8320 should be stored in closed containers and kept in a cool, dry place away from incompatible materials (see Section 10 of the SDS). Temperatures below 75°F (24°C) may thicken or solidify. It may be fluidized by warming with a drum heater or in a steam room, by heating gently and mixing to ensure it is homogenous prior to use. Drums should be vented prior to heating to avoid excessive pressure build up. Product temperatures over 130°F (54°C) are not recommended.
  • Bulk Storage Recommendations: TOXIMUL 8320 should be stored in vessels of stainless steel and glass fiber-reinforced polyester tanks. Many oven-cured phenolic and epoxy/phenolic linings may also be used. Elevated storage temperature may be desirable to maintain ease of pumping. Temperatures up to 130°F (54°C) can be maintained for long periods of time without degradation of the product.
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 safety practices should be used to control these exposures. See SDS for more information.
