10 Most Common Workplace Injuries and How First Aid Helps

Workplace injuries can happen fast.

One second, someone is lifting a box, walking across a wet floor, cutting open packaging, or climbing a ladder.

The next second, they’re hurt, shaken, bleeding, dizzy, or unable to keep working.

That’s why workplace injury first aid matters so much. It helps your team respond quickly, calmly, and safely when something goes wrong.

So, let’s talk about the injuries Canadian workplaces should be prepared for and how first aid can help.

Why Workplace Injury First Aid Matters

In Canada, there were 274,022 accepted lost time claims due to work-related injury or disease, along with 1,057 workplace fatalities. This shows just how real the risk is.

And behind every number is a person, a family, a team, and a workplace that had to react.

Every workplace has different hazards, but the goal is the same: be ready before the emergency happens.

That means having trained first aiders, accessible first aid kits, clear procedures, injury records, and, where appropriate, an AED.

It also means making sure your team knows what to do, who to call, and where supplies are kept.

Prepared workplaces don’t t just react better. They help employees feel safer.

1. Sprains, Strains, and Musculoskeletal Injuries

Sprains and strains are some of the most common workplace injuries, especially in jobs that involve lifting, bending, reaching, pulling, pushing, or repetitive movement.

WorkSafeBC reported that MSIs accounted for 30% of all time-loss claims and 26% of claim costs.

First aid helps by getting the worker to stop the activity, rest the injured area, apply cold if appropriate, elevate the injury, and avoid putting weight or pressure on it.

A trained first aider can also recognize when the injury needs medical attention.

2. Cuts and Lacerations

In 2024–2025 WSIB provincial data, cuts, lacerations, and punctures accounted for 8,295 claims, or 8% of the leading injury categories.

Cuts can happen anywhere sharp tools, glass, metal edges, knives, machinery, or packaging materials are used.

First aid helps control bleeding, protect the wound from contamination, and reduce the risk of infection.

The usual steps include putting on gloves, applying direct pressure, rinsing minor wounds, covering the area with a sterile dressing, and watching for signs that medical care is needed.

Deep cuts, embedded objects, uncontrolled bleeding, or wounds near joints, tendons, or the face should be treated as more serious.

3. Slips, Trips, and Same-Level Falls

Wet floors, loose mats, cords, clutter, uneven surfaces, snow, ice, and poor lighting can all turn a normal workday into a fall risk.

The Canadian Centre for Occupational Health and Safety (CCOHS) notes that 67% of falls happen on the same level as a result of slips and trips.

First aid helps by making sure the person is not rushed to stand up.

A first aider can check for head injury, dizziness, bleeding, swelling, pain, or signs of fracture.

Note that even a fall that looks minor can lead to a concussion, sprain, or fracture.

4. Falls From Heights

Falls from ladders, platforms, loading docks, roofs, stairs, or equipment can be extremely serious.

First aid helps protect the worker from further harm while emergency services are contacted.

If a neck, back, head, or major bone injury is suspected, the person shouldn’t be moved unless they’re in immediate danger.

First aiders can monitor breathing, control bleeding, keep the person still, treat for shock, and begin CPR or use an AED if the worker becomes unresponsive and isn’t breathing normally.

5. Burns and Scalds

Burns can come from hot surfaces, steam, grease, boiling water, chemicals, electricity, welding, or open flames.

First aid helps cool the burn, reduce pain, and limit tissue damage.

For thermal burns, cool running water is often used. Remove tight jewellery or clothing near the burn if it’s safe and not stuck to the skin. Cover the area with a clean, non-stick dressing.

Chemical burns require extra caution.

Your workplace should know where eyewash stations, safety showers, and Safety Data Sheets are located.

6. Eye Injuries

CCOHS reported that approximately 200 Canadian workers per day sustain a work-related eye injury, 90% of which would have been preventable with proper eye care and protection.

Eye injuries can happen from dust, chemicals, debris, tools, splashes, or flying particles.

First aid helps reduce the chance of permanent damage.

If there’s a chemical exposure, immediate flushing is critical.

If there’s a foreign object, don’t rub the eye or try to remove something embedded. Cover the eye if needed and get medical help.

A few seconds can make the difference when someone’s vision is at risk.

7. Back and Neck Injuries

Back and neck injuries may happen after lifting, twisting, falling, carrying heavy loads, or sudden awkward movement.

First aid helps by encouraging the person to stop, rest, and avoid making the injury worse.

If there’s numbness, tingling, weakness, severe pain, loss of bladder or bowel control, or a possible fall-related spinal injury, emergency medical care is needed.

This is where training is important. A first aider knows when “walk it off” is the wrong advice.

8. Crush Injuries, Fractures, and Dislocations

Crush injuries, broken bones, and dislocations can happen around machinery, vehicles, falling objects, tools, doors, and heavy materials.

First aid helps by keeping the injured area still, controlling bleeding, reducing swelling, and monitoring for shock.

Don’t try to straighten a broken bone or push a dislocated joint back into place.

If the injury involves severe pain, deformity, heavy bleeding, numbness, or a trapped body part, call emergency services.

9. Chemical, Fume, or Allergen Exposure

Some workplaces face exposure risks from cleaning products, solvents, gases, fumes, dust, food allergens, insect stings, or hazardous materials.

First aid helps by removing the person from the source if it’s safe, using proper protective equipment, flushing exposed skin or eyes when appropriate, and calling emergency help when symptoms are serious.

If someone is wheezing, swelling, struggling to breathe, or showing signs of anaphylaxis, treat it as an emergency.

10. Cardiac Arrest, Fainting, and Medical Emergencies

Not every workplace emergency starts with a visible injury.

Someone may collapse, faint, have chest pain, have a seizure, experience a stroke, or go into cardiac arrest.

First aid helps by giving bystanders a clear plan: check responsiveness, call 911, get the AED, start CPR if needed, and follow the AED prompts.

AEDs are designed to be easy to use, but confidence matters.

The more familiar your team is with CPR and AED response, the faster they can act when every second counts.

What Should Every Workplace Have Ready?

Think about your workplace for a moment. If someone collapsed, cut themselves badly, burned their hand, or fell on the stairs, would your team know exactly what to do?

If the answer is “not really,” that’s your sign to get prepared.

A strong workplace first aid plan should include:

• Trained first aiders
• Clearly marked first aid kits
• Emergency contact procedures
• Injury reporting and first aid records
• An AED setup
• Supplies suited to your workplace hazards
• Regular checks so supplies are stocked and ready
• Refresher training so employees stay confident
