Construction Jobsite First Aid Guide for General Contractors | Projul

Why First Aid Preparation Matters More Than You Think

Let me be honest with you. I’ve seen GCs who run tight ships on scheduling, budgeting, and quality control but treat first aid like an afterthought. They toss a dusty kit in the job trailer and call it good. Then somebody takes a nail through the hand, and suddenly nobody knows where the kit is, half the supplies are expired, and the nearest person with any training is on lunch break two miles away.

That’s not a plan. That’s a liability nightmare waiting to happen.

On a construction jobsite, injuries are not a matter of if, they’re a matter of when. Falls, cuts, burns, heat exhaustion, eye injuries, struck-by incidents. The list goes on. According to OSHA, the construction industry consistently accounts for the highest number of fatal work injuries of any sector. And for every fatality, there are hundreds of non-fatal injuries that could go sideways fast without proper first aid response.

The good news? Setting up proper first aid on your jobsites is not that complicated. It takes planning, some investment in training, and consistent follow-through. If you already have a solid construction safety plan, first aid preparation slots right into it.

Here’s what we’re going to cover: what goes into your first aid stations, where to put them, how to train your crews, what to do when something actually happens, and how to document everything so you’re protected. Let’s get into it.

Setting Up First Aid Stations That Actually Work

A first aid station is not just a white box with a red cross on it. At least, it shouldn’t be. Your station needs to be stocked for the specific hazards on your jobsite, positioned where people can get to it fast, and maintained consistently throughout the project.

What Goes in the Kit

OSHA standard 1926.50 requires “adequate” first aid supplies, which is intentionally vague because every jobsite is different. But here’s a solid baseline for a construction first aid station:

• Wound care: Adhesive bandages (assorted sizes), sterile gauze pads (3x3 and 4x4), gauze rolls, adhesive tape, butterfly closures, wound closure strips
• Bleeding control: Trauma dressings, hemostatic gauze, tourniquets (yes, tourniquets belong on construction sites)
• Burn treatment: Burn cream, burn dressings, cool gel packs
• Eye care: Sterile eye wash solution (at least 16 oz bottles), eye pads, eye cups
• Splinting and support: SAM splints, triangular bandages, elastic wraps
• Infection prevention: Antiseptic wipes, antibiotic ointment, hand sanitizer, nitrile gloves (multiple sizes), CPR pocket masks
• Tools: Trauma shears, tweezers, penlight, instant cold packs, emergency blankets
• Medications: Single-dose aspirin, ibuprofen, and acetaminophen packets (check your state laws on dispensing OTC medications)

For sites with specific hazards, add items accordingly. Doing hot work? Add more burn supplies. Working at heights? Include cervical collars and a backboard nearby. Chemical exposure risk? Add chemical-specific eye wash stations and decontamination supplies.

Where to Put Them

Location matters as much as contents. Here are the rules:

The four-minute rule. Any worker on your site should be able to reach a first aid station within four minutes. On a large commercial project, that means multiple stations. On a small residential remodel, one well-placed kit might cover it.

Accessible, not buried. Don’t put the kit in a locked trailer that only the super has keys to. Don’t put it behind stacks of material. Don’t put it in a location that requires climbing a ladder to reach. It needs to be at ground level, clearly marked, and accessible without any obstacles.

Mark them clearly. Use high-visibility signage. Every worker on site should know exactly where the nearest first aid station is. Include first aid station locations on your site map, and point them out during orientation.

Weather protection. Outdoor kits need to be in weatherproof containers. A soggy gauze pad is useless. Extreme heat can degrade medications and melt adhesives. If your kit is in a metal box sitting in direct sunlight in July, those supplies are toast.

Consider the work zones. If your project has multiple buildings, floors, or areas separated by significant distance, each area needs its own station. The crew framing on the third floor shouldn’t have to go to the ground level trailer to get a bandage.

Keep Them Stocked

This is where most GCs fall down. You set up a beautiful first aid station on day one, and by month three it’s been raided, expired, or both.

Assign someone, usually your safety lead or site superintendent, to inspect first aid stations weekly. Create a simple checklist and log the inspections. This takes five minutes, and it’s some of the most valuable documentation you can have if OSHA shows up or if you ever need to defend a workers’ comp claim.

Use your daily logs to note when supplies are restocked or when a kit was used. This creates a paper trail that shows you’re actively managing safety, not just checking a box.

Training Your Crews: Who Needs What

Having supplies on hand is only half the equation. If nobody knows how to use them, they’re just expensive decorations.

OSHA’s Minimum Requirement

Here’s what OSHA actually says: when there’s no infirmary, clinic, or hospital “in near proximity” to your workplace, you must have someone on site who is trained in first aid. OSHA has generally interpreted “near proximity” as three to four minutes of travel time.

Think about your typical jobsite. Is there a hospital three minutes away? Probably not. So you need trained people on site. Period.

Go Beyond the Minimum

One trained person is a bare minimum, and bare minimums are for contractors who like living dangerously. Here’s what a solid training program looks like:

Tier 1: Basic first aid awareness for every worker. Every single person on your jobsite should know the basics during orientation. Where are the first aid stations? How do you call for help? What does the emergency action plan say? This isn’t a certification course. It’s a 15-minute briefing that could save someone’s life.

Tier 2: Certified first aid/CPR for key personnel. Your superintendents, foremen, and safety leads should all hold current first aid and CPR certifications. The American Red Cross and American Heart Association both offer construction-specific courses that cover the injuries most common on jobsites. These certifications typically need renewal every two years.

Tier 3: Advanced first responder training for designated responders. On larger projects, consider having a few people with more advanced training. Stop the Bleed certification, for example, teaches tourniquet use and wound packing for severe bleeding, which is the number one preventable cause of death from traumatic injuries. This course takes about an hour and could literally be the difference between life and death on your site.

Making Training Stick

Here’s the thing about first aid training: people forget. You send your super to a Saturday CPR class, and six months later he can’t remember the compression ratio. That’s human nature.

Combat this with regular refreshers. Monthly toolbox talks should rotate through first aid topics. Run a scenario drill once a quarter. Keep it short, keep it practical, keep it real. “Hey, it’s Tuesday morning, and John just fell off a ladder and isn’t moving. Walk me through what you do.” Five minutes of that kind of exercise does more than an eight-hour classroom session that happened a year ago.

Track all your training in a system that keeps records organized. If you’re building out your training program across multiple projects, you need to know who’s certified, when their certs expire, and where the gaps are. Spreadsheets work until they don’t. At some point you need a real system.

When It Happens: Emergency Response on the Jobsite

Thousands of contractors have made the switch. See what they have to say.

All the preparation in the world means nothing if your people freeze up when something actually goes wrong. Your emergency response procedures need to be clear, practiced, and simple enough that someone running on adrenaline can follow them.

The Emergency Action Plan

Every project needs a site-specific emergency action plan (EAP). This is not the same as your company safety manual. It’s a document tailored to this specific project, this specific location, with this specific crew. Your EAP should include:

• Emergency phone numbers: 911 (obviously), but also the nearest trauma center, poison control, your company safety officer, and the project owner’s emergency contact
• Site address and directions: When you call 911 from a jobsite in the middle of a new subdivision with no street signs, you need to be able to give clear directions. Write these out in advance. Include GPS coordinates.
• Hospital route: Map out the fastest route to the nearest hospital. Print it. Post it. Include alternate routes for different times of day when traffic patterns change.
• Assembly points: Where does everyone go during an evacuation? Make it specific. “The parking lot” is not good enough when there are three parking lots.
• Communication plan: How do you notify everyone on a large site? Air horns? Radios? PA system? Know your method and make sure it works.
• Roles and responsibilities: Who calls 911? Who meets the ambulance? Who does a headcount? Who secures the scene? Don’t leave this to chance.

Post the EAP in the job trailer, at every first aid station, and at the main entrance. Review it during every new worker orientation. This ties directly into your overall OSHA compliance program.

The First Five Minutes

Most construction medical emergencies follow a predictable pattern in the first five minutes. Train your people to follow this sequence:

1. Scene safety. Before you touch the injured worker, make sure the hazard that caused the injury won’t hurt you too. Downed power line? Live excavation? Falling debris? Secure the scene first.

2. Call for help. Get someone on the phone with 911 immediately. Don’t wait to assess the severity. If there’s any doubt, make the call. You can always cancel an ambulance. You can’t undo a delayed response.

3. Control life threats. Severe bleeding, airway obstruction, cardiac arrest. These are the killers. Your trained responders should address these first and worry about everything else later.

4. Don’t move the patient (usually). Unless the scene is immediately dangerous, don’t move an injured worker. Spinal injuries are common in falls, and moving someone incorrectly can cause permanent damage.

5. Document everything. As soon as the immediate emergency is handled, start documenting. Use your phone to take photos of the scene, the conditions, and any equipment involved. Write down what happened, who was there, and what actions were taken. Do this while memories are fresh.

Specific Scenarios to Train For

Every jobsite is different, but these are the most common construction emergencies you should drill on:

Falls from height. The number one killer in construction. Your response protocol should assume spinal injury until proven otherwise. Stabilize, call EMS, and do not move the worker unless they’re in immediate danger.

Severe lacerations and amputations. Construction tools don’t mess around. Table saws, grinders, and power nailers can cause devastating injuries in an instant. Direct pressure, tourniquets for extremity wounds, and rapid EMS activation are the priorities. If there’s an amputated part, wrap it in moist sterile gauze, put it in a plastic bag, and place that bag on ice. Do not put the part directly on ice.

Electrocution. Do not touch the worker until the power source is confirmed de-energized. Use a non-conductive object to separate the worker from the source if you can’t cut power. Be prepared for cardiac arrest and begin CPR if needed.

Heat-related illness. This one sneaks up on people, especially during summer months. Know the difference between heat exhaustion and heat stroke. Heat exhaustion means rest, shade, and fluids. Heat stroke is a medical emergency requiring immediate 911 activation and rapid cooling. Build heat illness prevention into your daily planning during warm months.

Eye injuries. Extremely common on construction sites. For chemical exposure, flush with clean water for at least 15 minutes. For embedded objects, do not try to remove them. Cover the eye with a cup or shield and get to the ER.

Documentation and Record-Keeping

I know, I know. More paperwork. But listen, documentation is what protects you when things go sideways after the incident. The injury itself might cost you a few thousand dollars. A poorly documented injury can cost you hundreds of thousands in fines, lawsuits, and increased insurance premiums.

What to Document

Every incident, no matter how small. That little cut that “didn’t need anything but a Band-Aid”? Log it. Workers’ comp claims have a funny way of growing over time, and if you don’t have a record of the original incident, you’re fighting blind.

First aid kit inspections. Date, time, who inspected, what was found, what was restocked. Takes two minutes. Worth its weight in gold during an OSHA inspection.

Training records. Who was trained, on what, when, by whom, and when recertification is due. Keep copies of all certifications.

Emergency drills. Date, scenario, participants, what went well, what needs improvement. This shows OSHA and your insurance company that you’re actively preparing your crews, not just going through the motions.

Incident reports. For any injury that requires more than basic first aid, complete a detailed incident report. Include witness statements, photos, a description of events leading up to the incident, the response actions taken, and any contributing factors identified.

Build It Into Your Daily Routine

Documentation only works if it actually happens. And it only happens consistently if it’s built into existing workflows rather than treated as a separate chore.

Your daily logs should already capture safety-related observations. Add first aid activities to that workflow. If someone used the first aid kit today, it goes in the log. If you ran a drill during the morning meeting, it goes in the log. If you noticed a station needed restocking, that goes in there too.

Taking photos and organizing documents digitally means you’re not digging through filing cabinets six months later when the insurance adjuster comes calling. Snap a photo of the restocked kit, the posted EAP, the training sign-in sheet. It takes seconds and creates a timestamped record that’s hard to argue with.

Building a First Aid Culture on Your Jobsites

Here’s where I see the biggest gap between contractors who are good at first aid and contractors who are great at it. The good ones have the right supplies and training. The great ones have built a culture where every worker on site takes ownership of safety and emergency preparedness.

Lead from the Top

If the GC or superintendent treats first aid as a nuisance or a box to check, the crews will too. If leadership takes it seriously, actively participates in drills, personally checks the first aid stations, and talks about it regularly, the crews follow that lead.

I’ve seen supers who carry a personal trauma kit on their belt every day on site. That sends a message to every worker: this stuff matters, and we’re prepared.

Make It Easy to Report

Workers won’t report minor injuries if they think it’ll result in hassle, paperwork they have to fill out themselves, or being labeled as careless. Create an environment where reporting is quick, painless, and appreciated. A simple system where workers can log incidents without feeling like they’re being interrogated makes a huge difference.

Your daily log system should make it easy for field teams to capture safety events in real time without creating a bureaucratic headache.

Recognize Good Behavior

When someone handles a first aid situation well, recognize them. When a crew goes a month without an incident, call it out. Positive reinforcement works better than punishment every single time. Celebrate the crews and individuals who take first aid seriously, and others will follow.

Learn from Every Incident

After any injury or near-miss, do a quick debrief. What happened? Why? What could we do differently? Keep it non-punitive and focused on improvement. Share the lessons across your projects. If a crew on one site discovered that their first aid station was too far from the work area, every site should hear about it and check their own setups.

This kind of continuous improvement is the backbone of any serious safety program. It takes a few minutes per incident and prevents the same mistakes from repeating across your projects.

Know When to Call the Pros

Finally, make sure everyone understands the line between “we can handle this with our first aid training” and “this needs professional medical attention.” When in doubt, call 911. No one has ever been fired for calling an ambulance too early. Plenty of people have been sued for calling one too late.

As a general rule, any of the following should trigger an immediate 911 call:

• Loss of consciousness
• Difficulty breathing
• Severe bleeding that doesn’t stop with direct pressure
• Suspected spinal injury
• Chest pain
• Seizures
• Severe burns covering a large area
• Amputation or crush injuries
• Signs of heat stroke (confusion, loss of consciousness, hot dry skin)
• Electrical shock

For everything else, use your training, your supplies, and your judgment. And then document it all.

Putting It All Together

Setting up proper first aid on your construction jobsites is not rocket science, but it does require intentional effort. Stock the right supplies, put them where workers can actually reach them, train your people beyond the bare minimum, practice your emergency response, and document everything.

The contractors who do this well see fewer serious injuries, lower insurance premiums, fewer OSHA citations, and crews who trust that their employer actually cares about getting them home safe. That trust translates into better retention, better morale, and ultimately better work.
