Nitrous Oxide Scavenging and Exposure Monitoring Inspection

Inspection template for verifying nitrous oxide scavenging system performance, waste anesthetic gas controls, and staff exposure monitoring practices in clinical areas where N2O is used.

Inspection Details and Area Identification

• Inspection date and time recorded
• Inspection area identified
  Document the room, suite, department, or procedure area where nitrous oxide is used.
• Nitrous oxide use confirmed in this area
• Inspector name and signature completed

Scavenging System Condition and Connections

• Scavenging system connected to each active nitrous oxide delivery point
• Hoses, tubing, and connectors free of cracks, kinks, leaks, or disconnections
• Scavenging interface and mask seal appear intact during use
• Vacuum or suction source operating within expected range
  Record the measured suction or vacuum reading if available from the local system gauge or indicator.
• Scavenging flow or exhaust path unobstructed

Room Ventilation and Environmental Controls

• Mechanical ventilation operating during nitrous oxide use
• Air supply and return vents unobstructed
• Room odor or visible gas leakage noted
• Ventilation or exhaust deficiencies documented for follow-up

Staff Exposure Monitoring and Work Practices

• Staff exposure monitoring performed per facility program
• Measured nitrous oxide exposure at or below 25 ppm over 8 hours
  Record the most recent personal or area monitoring result in ppm.
• Staff using appropriate PPE and work practices to minimize exposure
• Leaks, open-flow use, or unnecessary exposure sources observed

Maintenance, Records, and Corrective Actions

• Preventive maintenance or service records current for scavenging equipment
• Deficiencies documented with owner and due date
• Staff trained on nitrous oxide scavenging and exposure controls
• Reference documents available for review
  Select the documents available during inspection.
