Checklist

Scope

Category 13 of 02 Audit Checklist Master Index (Hazardous Materials and Energy Hazards). It audits Hazardous Materials, CBRN and Energy Hazards Program (FSSMS-PRG-11), Policy - Hazardous Materials and WHMIS (FSSMS-POL-15), including the policy’s workplace WHMIS and hazard communication elements: the service level and competency levels; training; air monitoring; protective ensembles; entry, decontamination and exposure records; opioids, drugs and clandestine laboratories; electrical, solar, electric vehicle, lithium-ion, energy storage and gas hazards; pre-incident planning and dangerous goods; WHMIS and safety data sheets; CBRN; medical surveillance; learning; and the accountability loop with psychological safety. It is run annually by the internal audit under 01 Audit Program with the Hazardous Materials program manager, the HSO and the JOHSC consultant present, and every three years by an independent reviewer. The auditor samples every hazmat incident above awareness and every battery, energy storage, solar or gas incident in the last 12 months (or the last ten of each where there are more), one station’s WHMIS records, and one first-due apparatus’s instruments.

Criteria

The criteria are drawn from the responder competency standard (NFPA 470, 2022), the hazmat and CBRN ensemble standard (NFPA 1990, 2022), the chemical protective clothing, SCBA-in-IDLH and emergency operations provisions of the responder health and safety standard (NFPA 1550, 2024, ss. 9.6, 9.11.7 and ch. 10), the health and wellness standard for medical surveillance (NFPA 1580, 2025), the energy storage installation standard’s emergency response plan requirement (NFPA 855, 2026), the Canadian CBRN first-responder PPE standard (CSA Z1610-11), the respirator and breathing air standards (CSA Z94.4-18; CSA Z180.1:19), the federal WHMIS 2015 rules for supplier labels and safety data sheets (Hazardous Products Act [CA], 1985; Hazardous Products Regulations [CA], 2026), the opioid precautions for first responders (CCOHS, 2018), the lithium-ion and energy storage research and guidance (IAFF et al., 2023; MLITSD, n.d., GN 6-50, 6-51 and 6-53; NTSB, 2020), the applicable provincial or territorial rules on exposure records, protective equipment and respiratory protection, confined space, limits of approach to energized conductors, WHMIS and spills, and roadway operations (J09 Records Retention; J13 Firefighter PPE and Protective Equipment; J14 Respiratory Protection, Fit Testing and Breathing Air; J17 Confined Space; J19 Lockout, Machine Guarding and Electrical Safety; J21 WHMIS, Hazardous Materials and Asbestos; J30 Emergency Vehicles, Drivers and Licensing), and the accreditation criteria for the hazmat program, exposure reduction, contamination control and exposure records (CPSE, 2019, criteria CC 5H.1, 5H.2, CC 5H.3, 11A.4, 11A.9, 11A.10). The audit scores what is done at incidents and in stations and whether it works, not only what is written.

Scoring

0 not in place; 1 documented, not implemented; 2 implemented, not verified effective; 3 implemented and effective with evidence. The category score is the mean of the items scored; items marked not applicable (the technician sub-module switched off, no hydrogen infrastructure, no CBRN mission) are excluded. Score 3 only when the “3 looks like” description is met with evidence the auditor has seen; score 2 when the practice is observed but the verification evidence is missing; score 1 when only the document exists.

52	The program’s accountability and closed feedback loop operates: deficiencies logged within five working days with a priority from P1 (Imminent) to P4 (Improvement), verified closed, escalated on the schedule the item’s priority sets (Corrective Action Register), reported to the JOHSC and the fire chief	S1	Corrective Action Register; quarterly updates; JOHSC minutes	No overdue item without the escalation its priority requires; the loop test in the program can be traced on a real item (the instrument example or a real one)

Effectiveness questions (observation or interview only)

Pick a first-due apparatus and ask the crew, not the officer: “Show me the instrument. When was it bumped, what does it read right now, and what do you do if it reads 12 per cent LEL at the door?” The program is working when the bump is logged today, the member turns it on without hesitation, and the answer is leave or do not enter and tell command. It is not working when the instrument is in a cabinet with a flat battery or the answer is “keep going, it’s only 12”.
Ask an officer who has run a battery, EV or energy storage incident in the last year: “Walk me through it from the dispatch question to who has the battery now.” The program is working when the account includes SCBA after knockdown, a thermal imager watch with readings, a decision to cool or burn out that was announced, no overhaul, and a named person who was told in writing that it can reignite. It is not working when the account ends with “the tow truck took it”.
Ask a member who filed an exposure report in the last year: “What happened after you filed it, and would you file one again?” Then ask the HSO to show the register entry. The program is working when the member got an acknowledgement, can say where the record lives and how to get a copy, and says yes without hesitation; it is not working when the member does not know what became of it.
