A non-vented seal does its job the moment it goes on. The rest of the job is yours: watch the breathing, and burp the seal the moment it gets worse.
At a glance
10 things to know about the Beacon non-vented seal
Where a non-vented seal fits in TCCC, what this one is built to do, and how to keep the casualty safe under it.
-
01
A non-vented seal has a defined place
The TCCC Guidelines dated 1 May 2026 call for a vented chest seal on every open or sucking chest wound, and a non-vented seal when a vented one is not available — followed by monitoring for a developing tension pneumothorax.1 The civilian-focused C-TECC accepts non-vented seals used with reassessment, burping and decompression.8 Most seals placed on U.S. casualties with chest wounds in Afghanistan were non-vented.10
-
02
What it does — and what it cannot
The Beacon is an occlusive dressing for open chest wounds: sealed down, it stops air being drawn in through the hole.3 With no vent, air leaking from an injured lung inside the chest has no way out until someone lifts an edge.
-
03
Why the monitoring matters
In a 2013 U.S. Army swine study of another brand's non-vented seal, sealing restored breathing within five minutes — but with air still leaking into the chest, tension pneumothorax followed in all 8 animals after about 1.4 L, while a vented seal held through 2 L.7 That research moved TCCC to vented-first.6
-
04
Six-inch round
Beacon makes a large 6 in. round seal for coverage that conforms to the body's curves.3,4 The adhesive has to reach intact skin all the way around the wound, so center it carefully.
-
05
Hydrogel made for dirty skin
Beacon designs its medical-grade hydrogel to adhere to skin exposed to blood, sweat, hair, sand or water, and rates the seal effective in extreme cold and heat.3 Wipe the skin anyway: in testing, pooled blood has lifted chest seals off the skin.13
-
06
Transparent, with a large release tab
The clear backing lets you see the wound as you place the seal, and the large release tab makes it easy to apply — and to lift an edge later to burp it.3
-
07
Built for a pocket
The kit-size seal is vacuum-sealed in a lightweight, puncture-resistant pouch with a tear notch at each of four corners, and Beacon states its function and integrity survive being folded or rolled. It weighs about 1 oz.3
-
08
One seal — carry two
The kit size holds one seal, and a penetrating chest wound often has an exit. Carry a second seal, and check the back, sides and armpits before you call the chest done. Beacon also makes a two-pack.3
-
09
A vented sibling on the same platform
Beacon makes the same 6 in. hydrogel seal with four vents — the kit-size vented seal, item BCSK-VENT.3,4 When you have the choice, the TCCC Guidelines put the vented seal first.1
-
10
Not on the evidence-based device list — and no chest seal is
The Evidence-Based Standard Devices & Adjuncts list dated 15 December 2021 names no chest seal, so the Beacon is not evidence-based standard; absence from the list does not by itself mean a product was tested and failed.2 It is an FDA-registered, Class I (510(k)-exempt) occlusive wound dressing from Beacon Medical, LLC of Bloomington, Illinois.5
How to apply the Beacon seal
The sequence taught for chest seals under the TCCC Guidelines — with the monitoring a non-vented seal depends on.
-
1Expose and find every hole. Cut clothing away and look and feel front, back, sides and armpits. Life-threatening bleeding is controlled first — tourniquet, packing, pressure dressing.
-
2Cover it now. Put a gloved hand over the hole — or have the casualty do it — while you tear the pouch at a notch.
-
3Wipe it. Wipe blood, sweat and debris from the skin around the wound so the hydrogel lands on skin, not on fluid.
-
4Peel and place. Peel the backing using the release tab and place the seal centered over the wound, adhesive side down.3
-
5Smooth it down. Press from the center out so the edges seal all the way around.
-
6Seal the exit. Put a second seal on any other chest wound you found.
-
7Position and watch. Unconscious and breathing: recovery position. Conscious: let them sit up or take whatever position helps them breathe.1 Watch for increasing shortness of breath, falling oxygen and signs of shock.1
-
8Worse? Burp it. Lift an edge with the release tab to let trapped air escape, then press it back down — or remove the seal. Trained providers follow the Guidelines' decompression direction.1
Where it fits
- Open or sucking chest wounds when no vented seal is available1
- Kits built to a protocol that specifies a non-vented seal, with monitoring and burping trained8
- A compact backup seal in an IFAK, pocket kit or duty-belt kit3
- Skin exposed to blood, sweat, hair, sand or water, once wiped3
- Packing — never pack gauze into a chest or abdominal wound
- Over a protruding or impaled object — stabilize the object instead
- Leaving unwatched — a non-vented seal needs someone monitoring breathing1
- Limb bleeding — that is the tourniquet, packing gauze and pressure dressing
- Practice — train on a chest seal trainer
The evidence
Every study cited above, what it tested, and how strong it is.
| Study | Evidence type | What was studied | What it found |
|---|---|---|---|
| Kheirabadi et al., J Trauma Acute Care Surg 2013 | Animal · crossover | Unvented (HALO) vs vented (Bolin) seal on an open chest wound with an ongoing air leak, 8 swine | Both restored breathing within 5 min; the unvented seal led to tension pneumothorax in all 8 after ~1.4 L of air, the vented seal held through 2 L |
| Kheirabadi et al., J Trauma Acute Care Surg 2017 | Animal · comparative | Five vented seals on a bleeding open chest wound, 26 swine | Success ranged from 6/6 to 0/4; pooled blood lifted seals off the skin or clogged one-way valves |
| Schachner et al., Ann Thorac Surg 2022 | Bench · ex vivo | Improvised seals on a pig chest wall with a simulated open pneumothorax | Wet rescue-blanket squares sealed 5 of 5; plastic foil from a gauze wrapper sealed 0 of 5 |
| Schauer et al., J Spec Oper Med 2017 | Human · combat registry | 62 U.S. casualties with gunshot or puncture wounds to the chest, Afghanistan | 74.2% received a chest seal; most seals placed were not vented |
| Butler et al., J Spec Oper Med 2013 | Expert review · TCCC change 13-02 | evidence-based review of open pneumothorax care after the 2013 swine data | Vented chest seal first; non-vented if no vented seal; monitor, burp or remove, decompress |
| Margolis et al., J Spec Oper Med 2014 | Expert consensus · C-TECC | Committee for Tactical Emergency Casualty Care review of vented vs non-vented seals | Vented seals likely add benefit; non-vented users reassess, burp and decompress; no clear outcome superiority proven |
| Paquette et al., J Spec Oper Med 2021 | Systematic review | Six quantitative chest seal studies, 1990–2020 | HyFin Vent and Russell best supported; evidence on individual devices is limited |
| Lyng et al. (NAEMSP), Prehosp Emerg Care 2024 | Expert review · position statement | Structured review of EMS traumatic pneumothorax care | EMS may consider a vented seal in a spontaneously breathing patient; seals may be harmful during positive-pressure ventilation |
Strongest to weakest: human data, then animal studies, then bench work. The swine studies tested HALO, Bolin, HyFin, Russell, Sentinel and SAM seals; the Beacon was not among the brands compared, and a 2021 systematic review judged the evidence on individual brands limited.9

Both Beacon seals are 6 in. round.3,4 The Evidence-Based Standard Devices & Adjuncts list (15 December 2021) names no chest seal of any brand;2 absence from the list does not by itself mean a product was tested and failed.
