  • Hazardous Decomposition Products: Burning may produce phosphine (PH3 - toxic, flammable), oxides of phosphorus, and carbon monoxide.
  • Hazardous Polymerization: Will not occur.

2. Composition and Ingredients

While specific trade secrets apply, industrial biocides of this nature typically contain active ingredients designed to disrupt microbial cellular functions. Historically, products in the 8500 series often utilize oxidizing or non-oxidizing biocide chemistry.

  • Typical Active Ingredient: Often contains Isothiazolinone derivatives (such as Methylchloroisothiazolinone/Methylisothiazolinone) or Glutaraldehyde-based formulations, or a blend of quaternary ammonium compounds.
  • Appearance: Typically a clear to slightly hazy liquid.
  • Color: Often amber, yellow, or green tinted for identification.
  • Odor: Characteristic chemical odor; may be faint to strong depending on the specific active ingredient (aldehydes have a pungent smell, while isothiazolinones may be milder).

Personal Protective Equipment (PPE):

  • Respiratory: If TLV exceeded – wear a half-mask with particulate filter (N95 for dust; if chlorine gas present – acid gas cartridge).
  • Hands: Neoprene, nitrile (minimum thickness 0.4 mm), or butyl rubber gloves. Breakthrough time > 8 hours per MSDS. Replace if contaminated.
  • Eyes: Chemical splash goggles (not safety glasses) plus full-face shield.
  • Body: Chemical-resistant apron or full suit. Rubber boots.
  • Work Hygiene: Do not eat, drink, or smoke in work area. Wash hands thoroughly after handling.
