Smoke And Carbon Monoxide Detector Test
This procedure ensures all smoke and carbon monoxide detectors in an industrial facility remain functional and compliant with NFPA 72 and CSA B214 standards. It covers visual inspection, functional testing with certified aerosols and gases, and documentation of results.
To verify that every smoke and carbon monoxide detector installed in the facility is operational, within its calibration / expiration window, and capable of alerting personnel to a fire or hazardous gas condition. Regular testing reduces the risk of injury, property damage, and regulatory fines, and ensures compliance with the Canada Labour Code Part II and provincial fire codes (e.g., WorkSafeBC OHS Regulations).
This SOP applies to all fixed smoke (ionization, photoelectric, and multi‑sensor) and carbon monoxide detectors in industrial warehouses, manufacturing plants, machine shops, and storage facilities under the jurisdiction of Ryxen or its clients. Excluded: residential dwelling units (e.g., employee break rooms) are tested under a separate residential program. This procedure covers quarterly functional tests and annual sensitivity verification (using calibrated aerosol/gas).
- Lockout/tagout the fire alarm control panel before testing to prevent unwanted alarms triggering emergency response. Notify the facility control room and security team of scheduled testing.
- Use only certified CO test gas (50 ppm) from a calibrated cylinder. Never use vehicle exhaust or combustion by‑products — they contain other toxic gases and exceed safe exposure limits.
- When using a ladder to reach ceiling-mounted detectors, ensure it is on stable ground, within its rated capacity, and that a second technician acts as a spotter. Use a personal fall arrest system if working above 10 ft (3 m).
- Wear safety glasses, work gloves, and slip‑resistant footwear. If working near live electrical circuits, use insulated tools and maintain distance from exposed conductors.
- Smoke detector test aerosol (e.g., Solo 330 or equivalent)
- Carbon monoxide test gas (50 ppm CO in air, certified cylinder with regulator)
- Type 1A multi‑function ladder (300 lb capacity) — or scissors lift for high bay areas
- Personal fall arrest harness and lanyard (if above 10 ft)
- Lockout/tagout kit (lock, hasp, tag)
- Insulated screwdriver set
- Digital multimeter (calibrated within last 12 months)
- Safety glasses, work gloves, slip‑resistant boots
- Inspection logbook / digital tablet with SafeDesk app
- Spare detectors (matching make/model) for immediate replacement
