Phase 1: Identification & Area Isolation (0–2 Minutes)

Upon discovering an unknown chemical, biohazard, or hazardous substance leak:

• Assess & Identify: Evaluate the spill size and hazard type without directly touching or inhaling the substance.
• Isolate Immediate Zone: Block off physical access to the affected area, move residents away, and close nearby ventilation or HVAC returns if airborne hazards are suspected.
• Notify Leadership: Immediately inform the Charge Nurse / Maintenance Lead of the spill location and estimated volume.

Phase 2: Code Brown Activation & SDS Consultation (Minutes 2–5)

• Overhead Announcement: Page clearly three times over the PA system: "Code Brown – [Location/Unit/Room Number]".
• SDS Retrieval: Access the physical or electronic Safety Data Sheet (SDS) binder to determine chemical properties, neutralizing agents, and required PPE.
• Spill Kit Deployment: Designated spill response staff retrieve the centralized Chemical & Biohazard Emergency Spill Kit.

Phase 3: Containment, Cleanup & Neutralization (Minutes 5–20)

• Don Protective Gear: Responders equip full PPE specified by the SDS (e.g., chemical-resistant gloves, goggles, face shields, aprons).
• Dike & Contain: Apply absorbent dikes, pads, or spill-granules around the perimeter of the liquid to halt migration toward floor drains or resident corridors.
• Safe Disposal: Sweep or scoop contained materials into designated yellow biohazard or hazardous waste bags, sealing and labeling them according to environmental regulations.

Phase 4: Decontamination, Incident Logging & All-Clear (Post-Event)

• Decontaminate Surface: Sanitize the spill site using approved secondary disinfectants and allow required wet contact time.
• Overhead Announcement: Once the zone is fully decontaminated and safe for foot traffic, page: "Code Brown – All Clear, Code Brown – All Clear."
• Restock & Record: Restock used spill kit contents immediately and log the spill volume, root cause, and response steps in the facility safety binder.
