# **First Aid Preparedness on Construction Job Sites**
Construction sites present unique first aid challenges: remote locations, heavy equipment injuries, falls, and thermal emergencies. Proper first aid kits, trained personnel, and emergency response plans save lives.
**AVANORTH Team**
AVANORTH Construction
On a construction site, the time between an injury and professional medical treatment can be significant. Sites are often distant from hospitals. Paramedics need time to navigate site roads and reach the casualty. In those critical minutes, trained first aid responders with proper equipment can stabilize a worker, control bleeding, protect against shock, and make the difference between a full recovery and a permanent disability or death.

## Ontario First Aid Requirements
Ontario Regulation 1101 (Workplace Safety and Insurance Act) and the Construction Projects regulation (O. Reg. 213/91) establish minimum first aid requirements:
| Workers on Site | First Aid Kit | Trained Personnel | First Aid Room |
| --- | --- | --- | --- |
| 1-5 | Type 1 kit | 1 person with valid first aid certificate | Not required |
| 6-15 | Type 2 kit | 1 person with valid first aid certificate | Not required |
| 16-199 | Type 2 kit + extras | 1 per shift with Standard First Aid | Required (if no hospital within 20 min) |
| 200+ | Type 3 kit | 1 per 100 workers with Standard First Aid | Required |
---
## First Aid Kit Contents Beyond the Minimum
The regulation specifies minimum kit contents, but construction sites should supplement with items specific to construction hazards:
### Recommended Additions
- **Tourniquet (CAT or SOFTT-W):** For severe extremity bleeding from lacerations, amputations, or crush injuries. Construction has a high incidence of these injuries. A tourniquet can save a life in minutes when direct pressure is insufficient.
- **Hemostatic gauze (QuikClot, Celox):** For wound packing in areas where a tourniquet cannot be applied (torso, neck, groin)
- **Chest seal (vented):** For penetrating chest injuries (rebar impalement, nail gun)
- **Emergency blanket (mylar):** For shock management and hypothermia prevention
- **SAM splint:** Moldable aluminum splint for fractures
- **Burn gel packs:** For thermal and chemical burns
- **Eye wash station:** Minimum 1 litre of sterile saline for concrete splashes, grinding dust, or chemical exposure
- **AED (automated external defibrillator):** Not required by regulation for most sites, but strongly recommended for sites with 20+ workers
> **The Golden Hour:** Critical trauma patients have the best outcomes when they receive definitive medical care within 60 minutes of injury. On a construction site 20-30 minutes from a hospital, the first aid provided in the first 5-10 minutes determines whether the worker survives the trip to the emergency room.

## Common Construction Injuries and First Aid Response
| Injury | Immediate First Aid | Key Points |
| --- | --- | --- |
| Severe bleeding (laceration) | Direct pressure, tourniquet if needed, wound packing | Do not remove blood-soaked dressings, add more on top |
| Fall from height | Do NOT move the worker (spinal injury risk), stabilize, call 911 | Assume spinal injury until cleared by paramedics |
| Crush injury (equipment) | Do NOT release the crush until paramedics arrive (crush syndrome risk) | Releasing pressure can cause fatal cardiac arrhythmia from potassium release |
| Concrete burn (chemical) | Continuous flushing with water for 20+ minutes | Concrete is highly alkaline (pH 12-13), burns worsen without flushing |
| Heat stroke | Move to shade, remove excess clothing, cool aggressively (ice packs to neck, armpits, groin) | Heat stroke is a medical emergency, call 911 |
| Electrical shock | Do NOT touch the worker until power is confirmed off. Call 911. Begin CPR if no pulse. | Electrical injuries may have internal damage not visible externally |
| Impalement (rebar, nail) | Do NOT remove the object. Stabilize it in place. Control bleeding around it. | Removing the object can cause fatal bleeding |

## Emergency Response Plan
### Every Site Must Have
1. **Emergency contact list:** Posted at the site entrance and in the site trailer. Includes 911, nearest hospital address (with directions), project manager, safety coordinator, and utility locate numbers.
2. **Site access plan:** Ensure ambulances can reach the site. Mark and maintain access routes. If the site has restricted access (locked gates, narrow roads), designate a person to meet and guide the ambulance.
3. **Communication:** Cell phone coverage can be poor on construction sites both urban and rural. Verify coverage and have backup communication (radio, satellite phone for remote sites).
4. **Muster point:** Designated assembly area for evacuations. All workers must know the muster point location.
5. **Roles and responsibilities:** Clear assignments for who calls 911, who provides first aid, who directs the ambulance, who accounts for all workers at the muster point.
### Regular Drills
- Conduct a first aid drill (simulated casualty) at least once per major project phase
- Conduct a full evacuation drill at least once per project
- Review response times and identify improvements
> **AVANORTH Standard:** Every AVANORTH project has a written emergency response plan specific to that site. Our site supervisors hold current Standard First Aid with CPR-C certification. We stock enhanced first aid kits with tourniquets, hemostatic gauze, and burn supplies. We conduct a first aid scenario drill within the first month of every project. We believe that preparation is the difference between responding to an emergency and reacting to a crisis.
