Reactive Waste At SFSU

Back to Types of Waste Disposals At SFSU

Reactive waste refers to materials that are chemically unstable or reactive, capable of causing explosions, violent reactions, or toxic gas releases under certain conditions. These materials require stringent handling and disposal protocols to mitigate safety risks.

Characteristics of Reactive Waste:
• Can react violently with water, air, or other substances.
• Includes substances prone to detonation or explosive decomposition.
• Often generates toxic fumes, gases, or heat during reactions.

Reactive Waste Information

  • Peroxides and peroxide-forming chemicals (e.g., diethyl ether).
  • Reactive metals (e.g., sodium, potassium, magnesium).
  • Cyanides or sulfides that produce toxic gases when exposed to acids.
  • Picric acid or other unstable, shock-sensitive chemicals.
  • Compounds that undergo polymerization (e.g., styrene under heat).

  • Non-reactive, Compatible Containers: Designed to safely contain the specific reactive
    chemical (e.g., inert plastic or glass).
  • Ventilated Containers: For reactive chemicals that may produce gas pressure over time.
  • Secondary Containment: To prevent damage from leaks or reactions during storage or
    handling

Labels must include:

  • “Hazardous Waste – Reactive” or a similar designation.
  • Full chemical name(s) and associated hazards.
  • Date of accumulation and any specific handling instructions
  • 90 days in satellite accumulation areas (SAAs), as per regulatory guidelines.
  • Reactive waste must be monitored closely and removed promptly if instability is
    detected

Trained laboratory staff or Environmental Health and Safety (EHS) personnel handle the transfer of reactive waste to the designated hazardous waste storage area. Reactive waste is stored in a secure, segregated hazardous waste storage area, ensuring proper separation from incompatible materials

Reactive waste is picked up monthly or more frequently depending on the type and volume of waste generated. Emergency removal is arranged if instability is identified.

  • The waste is transported by a licensed hazardous waste disposal vendor specializing in
    reactive materials.
  • Disposal methods include:
    o Neutralization or chemical stabilization to render the waste non-reactive.
    o Controlled incineration in facilities designed for reactive chemicals.
    o Final disposal in regulated hazardous waste landfills if necessary.
