Storage & Handling

Storage Conditions
  • Keep combustible and/or flammable products and their vapors away from heat, sparks, flames and other sources of ignition including static discharge.
  • Processing or operating at temperatures near or above product flashpoint may pose a fire hazard.
  • Use appropriate grounding and bonding techniques to manage static discharge hazards.
  • Failure to maintain proper volume level when using immersion heaters can expose tank and solution to excessive heat resulting in a possible combustion hazard, particularly when plastic tanks are used.
  • Store products in tightly closed original containers at temperatures recommended on the product label.
