Stop the Bleed at Work: Why Every Construction Site Needs a Trauma Kit
A standard first aid kit is built to treat cuts. A trauma kit is built to keep someone alive long enough to reach the hospital. On a construction site, you need both—and most jobsites only have one.
It's 2:14 PM on a Tuesday. The framing crew on the third floor is finishing the last wall before break. A nail gun catches at the wrong angle, the operator pulls back hard, and the saw on the bench gets bumped. A coworker grabs for it. By the time anyone realizes what happened, blood is pulsing out of his upper thigh and pooling on the subfloor.
The 911 dispatcher says the ambulance is 11 minutes out.
He doesn't have 11 minutes.

Deaths in 2024 (BLS)
The Bureau of Labor Statistics recorded 1,032 fatal injuries among construction and extraction workers in 2024—more than any other occupational category. Severe bleeding from struck-by injuries, falls onto rebar, equipment failures, and saw incidents is one of the most preventable causes of those deaths. Not because the injuries themselves are avoidable, but because the window between the injury and a coworker controlling the bleeding is the difference between a survivable wound and a fatal one.
This is what the federal Stop the Bleed campaign was built to address. And it's why the trauma kit is no longer optional equipment on a job site.
First Aid Kit vs. Trauma Kit—They Solve Different Problems
A standard ANSI Class B first aid kit is built around the assumption that most workplace injuries are minor: cuts, abrasions, sprains, burns, headaches, eye irritation. Bandages, gauze pads, ibuprofen, antiseptic wipes. The standard 2021 revision added a single CAT tourniquet to Class B kits, which was a meaningful improvement—but a single tourniquet doesn't solve severe bleeding, it just gives you the option to start.
A trauma kit is built for the moments when somebody is going to die without immediate intervention. It assumes the worst possible version of a workplace injury: arterial bleeding, sucking chest wounds, crush injuries, junctional bleeding (groin, neck, armpit) where a standard tourniquet can't reach. The contents are organized for one purpose: keep the blood inside the body until EMS arrives.
What's in a Standard First Aid Kit
- Adhesive bandages, gauze pads, roller gauze
- Antiseptic wipes, antibiotic ointment
- Cold packs, burn dressings
- Basic medications (analgesics, antihistamines)
- One CAT tourniquet (added in 2021 to Class B kits)
- One SAM splint (Class B)
What's in a True Trauma Kit
- Multiple commercial tourniquets (CAT or SAM XT recommended)
- Hemostatic gauze (QuikClot, Combat Gauze, or equivalent)
- Compressed Israeli/emergency bandages with built-in pressure applicators
- Chest seals (vented, for sucking chest wounds)
- Trauma shears heavy enough to cut through denim, leather, and steel-toed boots
- Pressure dressings and large absorbent trauma pads
- Nitrile gloves (multiple pairs—they tear under stress)
- A clear, simple bleeding control reference card
Think of it this way: the first aid kit is for the injuries everyone has all the time. The trauma kit is for the one injury you hope never happens, but if it does, will define whether the day ends with everyone going home.
Why 5 Minutes Is the Number That Matters
An adult body holds about 5 liters of blood. A severed femoral artery, brachial artery, or major laceration to the trunk can lose 1.5 liters per minute. The human body cannot survive losing more than 40% of its blood volume.
EMS response times in the United States average 7–14 minutes from 911 call to on-scene arrival, depending on location. Construction sites in rural areas, on highway projects, in industrial zones, or anywhere outside dense urban cores routinely see EMS response times of 15–25 minutes. Helicopter EMS for severe trauma can take 30+ minutes from dispatch to landing.
The math is unforgiving. If somebody's femoral artery is severed and the nearest coworker doesn't have a tourniquet or doesn't know how to apply one, the patient will be dead before the ambulance crosses the property line. The first three minutes belong to whoever is on the jobsite.
The 3-Step Bleeding Control Method
The American College of Surgeons' Committee on Trauma has trained more than five million civilians in Stop the Bleed since 2015. The protocol is intentionally simple—it has to be teachable to non-medical bystanders in under an hour.
Call 911 yourself or assign the call by name to a specific person: "You, call 911 now." Ambiguous instructions get ignored under stress. Confirm scene safety before approaching the patient.
Find the source of bleeding. Cut away clothing if needed—you cannot treat what you cannot see. Identify whether the bleeding is from an extremity (use tourniquet) or torso/junctional area (use packing and pressure).
Apply firm, sustained direct pressure with hands or gauze; pack deep wounds with hemostatic gauze; apply a tourniquet 2–3 inches above an extremity wound if pressure alone won't stop bleeding. Note the time.
How to Apply a Tourniquet (CAT or SAM XT)
- Place 2–3 inches above the wound, on bare skin if possible, on the upper portion of the limb. Never over a joint.
- Pull the strap tight and secure it.
- Twist the windlass until bright red bleeding stops completely. Continue twisting until pulse below the tourniquet is gone. This will hurt the patient—that's expected and necessary.
- Secure the windlass in its locking mechanism.
- Write the time of application directly on the patient's skin or on the tourniquet's time strip. EMS needs this information.
- Do not loosen, reposition, or remove the tourniquet. Only EMS or hospital personnel do that.
For decades, civilian first aid courses taught that tourniquets caused more harm than good and should be a last resort. Combat data from Iraq and Afghanistan—where tourniquets are credited with saving thousands of lives—definitively reversed that guidance. Modern tourniquets applied correctly can be left in place for 2+ hours with minimal risk of limb loss. Hesitation kills more often than tourniquet application.
How to Pack a Wound
- For wounds where a tourniquet won't work (groin, neck, armpit, torso, deep extremity wounds): pack the wound cavity directly.
- Use hemostatic gauze if available (QuikClot Combat Gauze, Celox, ChitoGauze). Plain gauze works if that's all you have.
- Push gauze deep into the wound, packing it tightly against the bleeding source. This is uncomfortable to do—do it anyway.
- Hold firm direct pressure on the packed wound for a minimum of 3 minutes. Do not lift to check.
- Once bleeding is controlled, wrap with an Israeli/emergency bandage to maintain pressure.
What OSHA Says, and What Best Practice Says
OSHA's regulation under 29 CFR 1910.151(b) requires "adequate first aid supplies" be "readily available." The ANSI Z308.1-2021 Class B standard—which OSHA references as the compliance benchmark—requires a single CAT tourniquet as of the 2021 update.
That is the minimum, not the goal. OSHA's General Duty Clause, 29 U.S.C. § 654(a)(1), requires employers to provide a workplace "free from recognized hazards that are causing or are likely to cause death or serious physical harm." On a construction site, severe bleeding is a recognized hazard. A jobsite with a single tourniquet and no hemostatic gauze, chest seals, or backup tourniquets may meet the minimum compliance threshold while still being negligent under General Duty.
States are also beginning to legislate beyond the federal minimum. Missouri's Stop the Bleed Act, signed in 2025, requires Stop the Bleed kits and annual training in all public schools. Several other states have introduced similar legislation for workplaces. The regulatory direction is unambiguous: trauma kits and training are moving from optional to standard.
What Best-Practice Compliance Looks Like in 2026
- One ANSI-compliant Class B Type IV first aid kit per workgroup or per vehicle
- One dedicated trauma kit per workgroup, mounted in a visible high-traffic location
- At least 2 employees per shift trained in Stop the Bleed (one-hour course, free from the American College of Surgeons)
- Annual refresher training, documented
- Trauma kit inventory verified monthly, contents within expiration
- Clear bleeding control signage posted at the kit location
What a Trauma Kit Actually Costs—and What Not Having One Costs
A full commercial trauma kit costs between $200 and $600, depending on contents and container. Stop the Bleed training from the American College of Surgeons is free—the course materials are publicly available and the in-person component can be coordinated through local trauma surgeons, hospitals, and certified instructors at no cost.
A single fatal workplace injury costs an employer, on average, $1.34 million in direct costs (workers' comp, OSHA fines, legal settlements, equipment replacement) and several times that in indirect costs (downtime, investigation, reputational damage, insurance premium increases, lost productivity from affected crew). A single OSHA willful violation under the General Duty Clause can exceed $165,000.
The math is not subtle. A trauma kit is one of the cheapest pieces of safety equipment on a job site relative to the cost of not having one.
How the Beacon Kit PRO Functions as Both Standard & Trauma Kit
The Beacon Kit PRO is built specifically for the dual-need workplace—ANSI Z308.1-2021 Class B compliance for everyday injuries, plus a dedicated trauma response capability for the worst day on the job. Here's how the kit maps to bleeding control:
- Red (Trauma) Pouch: SAM XT tourniquet, QuikClot Combat Gauze (hemostatic), Israeli emergency bandage, vented chest seals, large trauma dressing. This pouch alone meets the core Stop the Bleed kit requirements.
- Green (Bandage) Pouch: Backup compressed gauze for wound packing, large absorbent pads, roller bandages for securing pressure dressings.
- Gray (Tools) Pouch: Heavy-duty trauma shears that cut through denim, leather, and steel-toed boot tops; nitrile gloves; permanent marker for noting tourniquet application time on patient skin.
- Blue (Environmental) Pouch: Mylar emergency blanket to maintain body temperature (severe blood loss patients become hypothermic fast, even in warm weather).
- Yellow (Ortho) Pouch: SAM splint and elastic wraps for orthopedic injuries that often co-occur with trauma (a fall that produces both a fracture and arterial bleeding).
Container: Type IV impact-resistant exterior survives drops, weather, vehicle vibration, and rough job-site handling. The bright yellow color is intentional—in an emergency, you need the kit visible from across the site.
Training Is Half the Kit
The kit itself is the easy part. The harder part is making sure someone on every shift knows how to use it under pressure. Stop the Bleed training takes about an hour, requires no medical background, and is available free through hospital trauma programs, fire departments, and the American College of Surgeons (stopthebleed.org). Schedule a class for your crew before the first hot weekend of the season. Document it. Refresh it annually.
A trauma kit nobody knows how to use is just a yellow box on a wall.
Do This Before Friday
- Audit every kit on every site. Is there a tourniquet? Hemostatic gauze? Chest seals? If the answer to any of those is no, you don't have a trauma kit yet.
- Identify your bleeding control responders. Minimum two trained people per shift. Write down their names. Post it at the kit.
- Book a Stop the Bleed class. Free at stopthebleed.org or through your local trauma center. One hour. No excuse to delay this.
- Practice tourniquet application. Buy a training tourniquet ($15) and have every responder apply it under a stopwatch. Goal: under 60 seconds.
- Walk the site. Where is the kit relative to where injuries are most likely? If it's locked in a job trailer 400 feet from the framing crew, it's not "readily available."
- Document everything. Training rosters, kit inventory checks, audit dates. This is your OSHA defense and your General Duty Clause defense.
The crews that go home every night are the ones where everyone knew what to do in the first three minutes.
