*Construction sites in Ontario are governed by two overlapping laws: Ontario Regulation 1101 under the Workplace Safety and Insurance Act (WSIA), which sets first aid kit contents and training requirements; and O. Reg. 213/91 under the Occupational Health and Safety Act (OHSA), which adds construction-specific requirements enforced by the Ministry of Labour, Immigration, Training and Skills Development (MLITSD). Quarterly inspections are the minimum; monthly is strongly recommended on active sites.

Part A: Construction Site & Hazard-Specific Standards

Kit Accessibility & Weather Protection: First aid kit is mounted or stored at a fixed, clearly identified location on-site — not locked inside a trailer or vehicle during work hours. Box is weatherproof and sealed against dust, moisture, and site debris. Must be accessible at all times when work is in progress (Reg. 1101, s.1).

Kit Signage & Visibility: First aid station is marked with a clearly visible white cross on green background sign, visible from a reasonable distance across the work area. Workers can identify its location without searching.

Eye Wash Station: A sterile saline eyewash (minimum 500 mL single-use bottle or fixed eye wash station) is available on-site. Check expiry dates. Critical for concrete dust, grinding sparks, chemical splashes, and sawdust exposure — one of the most frequent construction eye-injury mechanisms.

Burn Treatment Supplies: Hydrogel burn dressings are stocked and within expiry date. Gel must be fully hydrated and sealed. Required for welding and cutting operations, hot tar or bitumen work (O. Reg. 213/91, s.211), and contact with hot pipes or surfaces.

Splints (Assorted): Rigid and/or roll-up splints are stocked for suspected fractures and crush injuries — among the most common serious construction injuries involving falls from heights, struck-by incidents, and equipment contact.

Trauma / Pressure Dressings: Heavy-duty sterile dressings suitable for controlling significant bleeding are available. Verify individual wrapping is intact and items are within expiry. Construction lacerations from power tools, sharp materials, and sheetmetal are high-severity wound events.

Non-Latex Gloves & CPR Barrier Mask: Assorted sizes of non-latex disposable gloves and a CPR barrier/face shield are present at the station. (WSIB Guideline recommendation for all kits; critical infection control for first responders.)

Stretcher & Blankets (6+ workers): For sites with 6 or more workers, a stretcher and 2 blankets are provided, maintained, and accessible at or near the first aid station. (Required separately from the kit for all Section 9 and Section 10 workplaces — Reg. 1101, s.9 & s.10.)

Vehicle / Remote Area Kits: Workers operating in remote areas of the site, in company vehicles, or in locations more than a few minutes' travel from the main station have access to a portable first aid kit appropriate to the number of workers in that area. (Reg. 1101 requires prompt access — distance equals delay.)

Part B: WSIB & MLITSD Administrative Requirements

WSIB Form 82 Poster: "In Case of Injury or Illness at Work" poster is displayed at the first aid station and in all conspicuous places on the project. Download free at wsib.ca/case-injury-poster-form-82. (Required by Reg. 1101, s.1 & s.3)

Emergency Procedures Posted: A written emergency response plan — including procedures for fire, injury, entrapment, and evacuation — is posted in a conspicuous place on the project before work begins. (Required by O. Reg. 213/91, s.17. All workers must be made aware of these procedures.)

Nearest Hospital & Emergency Contacts Posted: The name, address, and route to the nearest hospital emergency department is posted at the first aid station and site office, along with local emergency services numbers (911) and the site supervisor's contact. (MLITSD/IHSA best practice; critical given construction site locations often outside urban centres.)

Inspection Card: The inspection card at the first aid station has been updated with the date of this inspection and the signature of the person conducting it. (Required quarterly minimum — Reg. 1101, s.6. Monthly recommended for active construction projects.)

First Aid Treatment Record: A written log is being maintained recording all workplace first aid events — including date/time, nature of injury, exact location on site, witnesses' names, and each treatment given. Records must be retained for a minimum of three years. (Required by Reg. 1101, s.5)

Trained First Aider on Site: At least one worker currently on site holds a valid first aid certificate (Emergency First Aid for ≤5 workers; Standard First Aid for 6+ workers) and their certificate is displayed or readily available at the station. First aider must be working in the immediate vicinity of the station. (Reg. 1101, s.8–10)

WSIB Form 7 Filed (if applicable): For any incident requiring health care beyond first aid, resulting in lost time, or requiring modified duties — a WSIB Employer's Report of Injury/Disease (Form 7) has been or will be submitted to WSIB within 3 business days of the employer learning of the reporting obligation. (WSIA, s.52; failure to report is an offence.)

WSIB Form 1000 (Employer Registration) On Site: Each constructor and employer engaged at the project has a completed WSIB registration Form 1000 on-site while work is underway. (O. Reg. 213/91, s.5)

Notice of Project (if required): If the project meets any trigger conditions under O. Reg. 213/91, s.6 (e.g., project valued at $50,000+, or involves excavation, tunnelling, demolition, or structural alteration), a Notice of Project has been filed with the MLITSD before work began.

Part C: AED Requirements — O. Reg. 157/25 (In Force January 1, 2026)

AED Applicability Check: Confirm whether this project is subject to the AED requirement: Does it regularly employ 20 or more workers AND is work expected to last 3 months or more? If YES to both, all items below are legally mandatory. If NO to either condition, this section is exempt — document your determination for inspection records.

AED Installed & Accessible: A Health Canada–licensed automated external defibrillator (AED) is installed and maintained at the project in a clearly marked, accessible location during all work hours. (O. Reg. 213/91, s.27.1, as amended by O. Reg. 157/25)

AED Accessories Stocked: Confirm that the following items are stored with the AED and replenished as necessary: adult defibrillation pads; pediatric pads or attenuator; razor; scissors; non-latex gloves; CPR barrier mask; and absorbent cloth/towel.

AED Maintenance & Readiness: AED unit is in functional condition — status indicator shows ready, battery charge is sufficient, electrode pads are within their expiry date, and the unit is stored in a clean, accessible location that protects it from construction site environmental damage.

Trained AED Operator On Site: At least one trained first aid operator with AED certification is present on site whenever work is underway. This may be the same person as the required first aider. (O. Reg. 213/91, s.27.1(3))

Government Reimbursement (if applicable): If an AED was purchased between July 1, 2025 and June 30, 2027 for a qualifying project, confirm whether a reimbursement application has been submitted or is planned. Applications are expected to open January 1, 2026. (One AED reimbursement per eligible project.)
