> **Warning: Before adoption**
>
> This model policy requires review by the department’s legal counsel and against the collective agreement and the volunteer by-law before adoption. It is general information, not legal advice. Where it conflicts with a statute, regulation or agreement, the statute, regulation or agreement governs. Section numbers of standards and laws are cited as of October 2026; confirm each before adoption.
## How to use this model
**Format.** Adopt as a policy approved by the fire chief or council, as a standard operating guideline, or as a directive; keep the numbering, because the program, the forms and the audit checklist refer to it.
**Drafting conventions.** **Shall** is mandatory; **should** is expected unless a documented reason exists; **may** is permitted. Placeholders in double curly braces, such as `{{Department}}`, are completed by the department. Drafting notes appear in callouts and are removed before adoption.
**Keep intact:** the essential job task anchor (5.2), the fitness-for-duty and accommodation test (5.4), the custodian rule (5.9), the non-punitive fitness program (5.5), the fatigue self-declaration (5.6), and the learning firewall (4(d) and 5.11). **Adapt:** tiers and intervals, the physician arrangement, the fatigue limits, and the roles mapping.

## 1. Purpose
1.1 To commit the department to keeping every member medically and physically able to do the work safely across a career, to protecting members’ health information, and to managing fatigue as a hazard.
1.2 To set out who is accountable for each commitment and to point to the program and procedures that carry it out.
## 2. Scope and application
2.1 This policy applies to every operational member of the department, career, volunteer and paid-on-call, and to candidates for operational roles.
2.2 Non-operational staff are covered by sections 5.6 (fatigue), 5.7 (return to work), 5.8 (wellness) and 5.9 (health information), and by any medical requirement attached to their duties.
2.3 Incident and training rehabilitation, hearing conservation, occupational cancer screening and psychological health are governed by their own programs and, where applicable, their own policies, and are referenced here.
2.4 Nothing in this policy limits a member’s rights under the applicable human rights, workers’ compensation or occupational health and safety legislation, or under the collective agreement.
## 3. Definitions
Terms in bold are used as defined here and in [06 Glossary and Acronyms](https://thehumanfactor.ca/library/fire-service-safety/glossary-and-acronyms).
- **Accommodation**: a change to duties, equipment, schedule or role that lets a member with a restriction do the work safely, up to the point of undue hardship.
- **Bona fide occupational requirement (BFOR)**: a standard rationally connected to the job, adopted in good faith, and reasonably necessary because the member cannot be accommodated without undue hardship (*British Columbia (Public Service Employee Relations Commission) v. BCGSEU*, 1999).
- **Essential job tasks**: the written list of tasks an operational role must be able to perform, approved under 5.2.
- **Fatigue**: a state of reduced mental or physical capacity resulting from sleep loss, extended wakefulness, workload or circadian disruption.
- **Fire department physician**: the physician or clinic lead designated under 5.1.
- **Fitness-for-duty determination**: the physician’s categorized conclusion about a member’s ability to perform the essential job tasks.
- **Health information**: any information about a member’s physical or mental health, including results, diagnoses and fitness assessment scores.
- **Learning firewall**: the commitment that information gathered for learning is not used for discipline.
- **Member**: any career, volunteer or paid-on-call firefighter or officer, and any other person the department engages in operational work.
- **Psychological safety**: the shared belief in a team that it is safe to speak up, ask, admit error and challenge [(Edmondson, 1999)](https://thehumanfactor.ca/library/fire-service-safety/policy-occupational-medical-fitness-and-wellness#ref-edmondson-1999).
## 4. Principles
1. **People are the solution we build around, not the problem to fix.** Members arrive wanting to be fit and well for the work; this policy gives them the physician, the time, the equipment and the privacy to be so.
2. **Procedures describe work as done, written with the people who do it.** The medical, fitness, fatigue and return-to-work procedures are designed with learning teams of members who have been through them.
3. **Learning comes before blame, and learning information is never used for discipline.** A hidden symptom, a missed medical or a shift worked past the limit is a signal about the system; the response is to find out why.
4. **Psychological safety is a condition of safety, so speaking up is expected and protected.** A member who says “I am not fit for this today” has done their job; the officer’s job is to act on it.
5. **One standard, applied fairly.** Medical and fitness standards are anchored to the essential job tasks, validated, applied individually, and never used adversely without the BFOR test and the duty to accommodate.
6. **The department holds the determination, never the chart.** Health information stays with the custodian.
7. **Volunteers are members.** The standard is the same; the method is scaled to make it achievable.
## 5. Policy statements
### 5.1 Fire department physician
5.1.1 The department **shall** designate a fire department physician under a written agreement that sets scope, confidentiality, turnaround and cost, and **shall** orient the physician to the essential job tasks, the exposure profile and the work. Accountable: {{Fire Chief}}.
5.1.2 The physician **shall** evaluate members against the essential job tasks and the criteria of [NFPA 1580 (2025)](https://thehumanfactor.ca/library/fire-service-safety/policy-occupational-medical-fitness-and-wellness#ref-nfpa-1580) and **shall** report to the department only a fitness-for-duty determination.

5.3.4 The annual evaluation **shall** include cardiac risk stratification and an exercise stress test where the member’s age or risk profile indicates it [(NFPA 1580, 2025)](https://thehumanfactor.ca/library/fire-service-safety/policy-occupational-medical-fitness-and-wellness#ref-nfpa-1580).
5.3.5 Medical evaluations **shall** be provided at department cost, on duty for career members and at times volunteers can attend.
### 5.4 Fitness for duty, restrictions and accommodation
5.4.1 The physician **shall** determine fitness in one of the categories in the program; the department, not the physician, **shall** decide assignment and accommodation.
5.4.2 Before any member is removed from a role on a medical or fitness ground, the department **shall** apply the three-step BFOR test, **shall** consider individual assessment, modified duties, alternative roles and a time-limited improvement plan, and **shall** document the hardship analysis for any option rejected. Accountable: {{Deputy Chief}} with corporate human resources.
5.4.3 A member **may** be accompanied by a union or association representative at every step, and **may** ask the fire chief to review the decision; the grievance and human rights processes are unaffected.
5.4.4 A volunteer who is not cleared for a role **shall** be assigned to roles for which they are cleared, as an accommodation and not a penalty.
### 5.5 Health-related fitness
5.5.1 The department **shall** provide a health-related fitness program with an annual assessment, an individual exercise prescription, certified peer fitness trainers and station equipment, on duty for career members and credited for volunteers. Accountable: {{Deputy Chief}}.
5.5.2 The fitness program **shall** be non-punitive: no assessment result **shall** be the basis for discipline or removal from duty, and individual results **shall** be held by the peer fitness trainer and the member, not the department.
5.5.3 Participation in the assessment **should** be mandatory from {{Stage 2 date}}, by agreement with the union and the association.
### 5.6 Sleep, fatigue and hours of work
5.6.1 The department **shall** manage fatigue as a hazard through the limits and rules in [Policy - Fatigue and Hours of Work](https://thehumanfactor.ca/library/fire-service-safety/policy-fatigue-and-hours-of-work) and the program, including a maximum continuous duty period, minimum rest, post-incident rest, and sleep-disorder screening in the medical.
5.6.2 Any member **may** declare fatigue to their officer at any time; the officer **shall** reassign the member; no penalty **shall** follow. Accountable: every company officer.
### 5.7 Return to work and stay at work
5.7.1 The department **shall** operate a work disability management program aligned to CSA Z1011:20, with a named coordinator, first contact within three working days of a lost-time injury, a modified-duties list, and a written graduated plan, for physical and psychological injury alike. Accountable: {{Deputy Chief}} with corporate human resources.
### 5.8 Immunization, vision, hearing and wellness
5.8.1 The department **shall** offer the immunizations in the program schedule at department cost, **shall** assess vision and hearing in every medical, **shall** operate the [Hearing Conservation Program](https://thehumanfactor.ca/library/fire-service-safety/hearing-conservation-program), and **shall** provide health education and cessation and nutrition support.
### 5.9 Health information
5.9.1 Health information **shall** be held by the physician, clinic, assistance provider or peer fitness trainer as custodian. The department **shall** hold only fitness-for-duty determinations, restrictions, status flags, tracker dates, accommodation and return-to-work files held by human resources, and aggregate statistics at cell sizes of 10 or more. Accountable: {{Division Chief, Safety}}.
5.9.2 A written information-sharing protocol **shall** name what crosses from the custodian to the department: the determination and restrictions; imminent risk to the extent the law permits; and what the member consents to in writing.
5.9.3 Members **shall** have access to their own department records within 10 working days.
### 5.10 Rehabilitation at incidents and training
5.10.1 Rehabilitation **shall** be established at every incident and training evolution that meets the triggers in [Firefighter Rehabilitation Program](https://thehumanfactor.ca/library/fire-service-safety/firefighter-rehabilitation-program), with medical monitoring on entry and release, and no member **shall** self-release.
### 5.11 Speaking up and learning
5.11.1 Every member is expected to speak up about their own or a colleague’s fitness for a task, and is protected from reprisal for doing so.
5.11.2 Information gathered in learning teams, after-action reviews, fatigue declarations and program evaluation **shall** not be used for discipline. Conduct concerns **shall** be handled by a separate process run by different people.
5.11.3 Any member’s concern about this policy or the program **shall** receive an answer within 10 working days through the route in the program.
## 6. Roles and responsibilities
Only the differences from [01 Roles and Responsibilities](https://thehumanfactor.ca/library/fire-service-safety/roles-and-responsibilities).

6.3 **Program manager, Health, Wellness and Rehab team**: runs the program, the tracker, the appraisal and the budget worksheet.
6.4 **Fire department physician**: evaluations, determinations, respirator clearance, return-to-work determinations, clinical advice to the team.
6.5 **Health and safety officer**: verifies the tracker and the custody of records; samples quarterly; maintains the information-sharing protocol.
6.6 **Company officers**: release members for evaluations; act on fatigue declarations and fitness concerns; first-level return-to-work contact.
6.7 **Members**: attend evaluations; take part in fitness; declare fatigue and unfitness; keep immunizations current.
6.8 **Peer fitness trainers**: assessments and prescriptions in confidence.
6.9 **Corporate human resources**: accommodation and return-to-work administration; custody of case files; compensation claims.
6.10 **JOHSC**: consulted on the program and every change; receives the aggregate report twice a year.

([J22 Exposure Limits, Heat and Cold Stress](https://thehumanfactor.ca/library/fire-service-safety/j22-exposure-limits-heat-and-cold-stress)); and respiratory protection, including medical clearance ([J14 Respiratory Protection, Fit Testing and Breathing Air](https://thehumanfactor.ca/library/fire-service-safety/j14-respiratory-protection-fit-testing-and-breathing-air)).
- [NFPA 1580 (2025)](https://thehumanfactor.ca/library/fire-service-safety/policy-occupational-medical-fitness-and-wellness#ref-nfpa-1580): medical program, fitness, rehabilitation, infection control; NFPA 1550 (2024, ch. 13).
- CSA Z94.4-18: medical clearance for respirator use.
- CSA Z1011:20: work disability management; CSA Z1008:21: impairment.
- The Wellness-Fitness Initiative [(IAFF & IAFC, 2018)](https://thehumanfactor.ca/library/fire-service-safety/policy-occupational-medical-fitness-and-wellness#ref-iaff-2018).
- The applicable human rights legislation and its duty to accommodate ([J33 Return to Work, Accommodation and Hours of Work](https://thehumanfactor.ca/library/fire-service-safety/j33-return-to-work-accommodation-and-hours-of-work)), and the BFOR test (*British Columbia (Public Service Employee Relations Commission) v. BCGSEU*, 1999).

## 12. Review and approval
12.1 This policy is reviewed 12 months after adoption and then every three years; after any cardiac death or serious medical event on duty; after any change in the law or the standards; and at the JOHSC’s request.
12.2 Approved: {{Fire Chief}} (role), date. JOHSC consulted: date. Union and association consulted: date.
## 13. Adoption checklist
| Step | Lead | Done |
|:---|:---|:---|
| Counsel review of this policy against the statutes and the collective agreement | {{Division Chief, Safety}} | |
| Essential job task list drafted with a learning team and approved | Program manager | |
| Physician or clinic agreement signed; orientation held | {{Deputy Chief}} | |
| Volunteer tiers and intervals decided | Program manager | |
| Fatigue limits set and reconciled with the collective agreement and by-law | {{Deputy Chief}} | |
| Modified-duties list and return-to-work coordinator named | Human resources | |
| Information-sharing protocol signed with each custodian | {{Division Chief, Safety}} | |
| Tracker built in the records system | Program manager | |
| JOHSC consultation recorded; union and association consultation recorded | {{Division Chief, Safety}} | |
| Policy approved and posted; members briefed at every station | {{Fire Chief}} | |
| First quarter: SCBA clearances complete for every SCBA-qualified member | Program manager | |
| 12-month review scheduled | Policy owner | |
## 14. Consulting the JOHSC and bargaining agents
Consult early, in writing, and record the outcome. What they will ask, and honest answers:
| They will ask | Honest answer |
|:---|:---|
| Will the department see my results? | No. The custodian holds them. The department sees a category and restrictions by task number, nothing else. The protocol is written and you can read it. |
| Can a fitness score get me taken off the truck? | No. Fitness scores are non-punitive and stay with the trainer. Only the physician’s determination against the essential job tasks affects assignment, and then the BFOR test and accommodation apply, with representation. |
| Will older members be pushed out by percentiles? | No standard is applied adversely without the three-step test, individual assessment and accommodation. The percentile method is reconciled with the actual task demands first. |
| Will volunteers be forced out by medicals? | Volunteers not cleared for a role are assigned to roles they are cleared for. Clinic nights at the hall make the medical reachable. The SCBA medical clearance comes from the respirator standard (CSA Z94.4-18) and, where the regulation adopts that standard, from the law ([J14 Respiratory Protection, Fit Testing and Breathing Air](https://thehumanfactor.ca/library/fire-service-safety/j14-respiratory-protection-fit-testing-and-breathing-air)); it is not the department’s choice. |
| Who pays, and on whose time? | The department pays; career members attend on duty; volunteers at times they can attend, with time credited. |
| What happens if I declare fatigue? | You are reassigned and nothing else happens. Declarations are counted without names so the department can see where fatigue is coming from. |
Put the agreements in a letter of understanding; where you disagree, record it, adopt what you can, and review at 12 months. Volunteers and non-union staff need their own voice in the consultation.
## 15. Customization and sector variants
> **Note: Customize**
>
> Complete every placeholder in double curly braces; decide the volunteer tiers, the fatigue limits and the Stage 2 date for mandatory fitness assessment; map the roles in section 6 to the department’s ranks; confirm your jurisdiction’s requirements on the topic pages listed under Jurisdiction requirements; delete the drafting callouts.
> **Tip: Volunteer and composite departments**
>
> Keep 5.3.2 and 5.3.3 intact; they are the two clauses that protect volunteers’ lives. Adapt the method (clinic nights, family physician forms with the task list) rather than the standard.
> **Information: Delivery note**
>
> Table this policy with the physician present and the information-sharing protocol already drafted. Most objections are about privacy and most are resolved by showing the protocol.
**Closing disclaimer.** This model policy is general information prepared by The Human Factor for adaptation by the adopting department. It is not legal advice. The department remains responsible for compliance with the law that applies to it. Confirm every citation with counsel before adoption.
*End of model policy.*
