Spill Response in a Non-Hazardous Compounding Suite
During a night shift, a technician drops a 1 L bag of 0.9% sodium chloride onto the floor of an ISO Class 7 buffer room. The bag ruptures and approximately 400 mL spreads across the floor and under a stainless steel cart. No hazardous drugs are involved. The room's pressure differential is +0.04 inches w.c. relative to the ante room, and the ante room is +0.02 relative to the corridor. The technician is wearing a gown, gloves, and a bouffant cap. A second technician is preparing a batch of non-hazardous antibiotics in the adjacent ISO Class 5 hood. The facility's spill kit is in the ante room. The night supervisor asks whether the room must be shut down and whether the batch in progress can continue.

Immediate response:
- Stop and secure: The technician should stop work, avoid walking through the spill, and alert the second technician.
- PPE: Add shoe covers and a fluid-resistant gown if not already worn; the existing gloves are appropriate for a non-hazardous saline spill.
- Contain: Use the spill kit's absorbent pads to contain the 400 mL, working from the outside in. Do not use a mop that will spread contamination.
- Clean and disinfect: Remove the absorbed material into a biohazard or regular waste bag per policy, then clean the floor with detergent and disinfect with an EPA-registered disinfectant appropriate for the surface.
- Dry: Allow the floor to dry fully before resuming traffic.
Can the adjacent batch continue? The spill is in the buffer room, not inside the ISO Class 5 hood, and the pressure differential remains positive (+0.04 inches w.c.). If the spill is contained and does not enter the hood or the ante room, the second technician may continue compounding only if the spill does not compromise airflow or introduce aerosols near the hood intake. Best practice is to pause the batch until the spill is contained, then resume after verifying the hood is undisturbed.
Model answer: Contain and clean the spill, verify the hood and pressure differential are intact, and pause compounding until the spill is controlled.
2. What environmental monitoring and documentation should follow the spill?
Read the worked answer
Follow-up monitoring and documentation:
- Pressure differential log: Record the reading before, during, and after the spill to confirm the buffer room remained positive relative to the ante room.
- Nonviable particle count: If the spill generated aerosols or required significant agitation, perform a particle count after cleaning and before resuming compounding.
- Viable air and surface sampling: Increase surface sampling of the floor and cart area; document results.
- Spill report: Record the time, volume, location, PPE used, cleaning agents, and personnel involved.
- Corrective action: Evaluate why the bag was dropped (e.g., wet gloves, overcrowded cart) and adjust workflow.
Model answer: Log pressure differentials, perform particle and surface monitoring as indicated, complete a spill report, and implement a corrective action.
