A 4 in. bandage cannot dress an above-knee amputation or a burned back. The BLAST Bandage can — after the tourniquet is on.
At a glance
12 things to know about the BLAST Bandage
What it covers, what each part is for, where the TCCC Guidelines put it, and what it is not.
-
01
A pad big enough for a back or a chest
The non-adherent sterile wound pad measures 19.5 × 19.5 in. on TacMed's specification sheet — TacMed markets it as a 20 × 20 in. treatment area — large enough to cover the entire back or chest of most casualties.3,4
-
02
It packs like a 4 in. bandage
The package is 9.5 × 6.5 × 2.5 in. and compacts to 5 × 3 × 2.5 in.; the whole bandage weighs 3.8 oz.4 TacMed's point: about the size of a standard 4 in. combat bandage.3
-
03
Designed around the amputation stump
TacMed's patent for the BLAST describes dressing a severed limb: an oversized pad placed against the stump, folded over to envelope it, and held by an elastic bandage attached at a right angle to a corner of the pad.7 Any traumatic amputation gets a limb tourniquet first; the BLAST dresses the stump.1
-
04
For burns and large pattern wounds
TacMed's intended use is coverage and treatment of large wound patterns and burns.4 The TCCC Guidelines direct covering a burn with dry, sterile dressings, and warn that burn casualties are particularly prone to hypothermia.1
-
05
An occlusive sheet behind the pad
A plastic occlusive sheet sits behind the wound pad and comes out when needed; TacMed's specification sheet sizes it at 15.8 × 15.8 in. (40 × 40 cm).3,4 TacMed's stated use for it: covering abdominal contents to cut the loss of heat and moisture.3
-
06
Evisceration: cover, don't force
The TCCC Guidelines: control bleeding, rinse gross contamination, and cover exposed bowel with a moist sterile dressing or a sterile water-impermeable covering; a single brief attempt to reduce is allowed only when there is no leakage and no active bleeding — never force contents back.1,8
-
07
Open chest wound: a chest seal comes first
TacMed describes the sheet for sealing chest wounds.3 The TCCC Guidelines call for a vented chest seal on an open or sucking chest wound, and a non-vented seal when no vented one is available.1 A plain occlusive sheet works as a non-vented seal: watch breathing, and burp or lift it if breathing gets worse.1
-
08
Brakes and a clip
Hook-and-loop control strips built into the elastic prevent accidental unrolling and give multiple points of grip so the elastic does not slip while you wrap — TacMed calls out amputations as where they help most. A securing clip locks the bandage and frees your hands.3,4
-
09
Not a hemostatic, and not a junctional device
The BLAST pad carries no clotting agent and does not replace packing. A deep wound, or a wound in the groin, armpit or neck, is packed first and held; the BLAST can cover a large area over it. Never pack the chest or abdomen. Hands come first: across studies, direct manual pressure stopped bleeding faster than pressure dressings,13 while an elastic compression dressing over gauze controlled 87% of bleeding wounds in one field series.9
-
10
Sterile, latex-free, six-year shelf life
Packaged sterile, single use, with a shelf life of 6 years from the date of sterilization.4,5 Materials: ABS, latex-free elastic, nylon, non-woven polyester and a thermo-bonded rayon filler.4
-
11
NSN-assigned and FDA-registered
NSN 6510-01-586-4314, issued each.6 AccessGUDID lists it as a compression dressing — FDA product code MHW, Class I, exempt from premarket notification — under DI 00818630010289.5
-
12
Know which side goes down
The outer face of the pad is printed "OTHER SIDE TOWARD WOUND" — the printing faces out, the unprinted side goes on the wound.3
How to apply the BLAST Bandage
Bleeding control first, then coverage — the order taught in TCCC and TECC.
-
1Tourniquet first. Any traumatic amputation and any life-threatening limb bleed get a tourniquet. Under threat or with the source hidden: high and tight, over clothing. Once exposed: on bare skin 2–3 in. above the wound, never across a joint.1
-
2Pack what needs packing. Deep or junctional wounds are packed — power ball on the bleeding vessel, every corner tight — and held: at least 3 minutes or the labeled time for hemostatic gauze,1 at least 10 minutes for plain gauze, or until bleeding stops. Never pack the chest or abdomen.
-
3Open and orient the pad. Tear the pouch, unfold the pad, and put the unprinted side on the wound — the printed "OTHER SIDE TOWARD WOUND" face goes out.3
-
4Amputation stump: envelope it. Place the pad against the stump, fold it over to envelope the end of the limb, and wrap the attached elastic around the limb and the folded pad.7
-
5Large wound or burn: cover and wrap. Lay the pad over the area and wrap the elastic to hold it. Use the control strips to keep the roll from running away, then lock it with the securing clip.3,4
-
6Keep the tourniquet visible. Do not bury a tourniquet under the dressing. The TCCC Guidelines direct that every tourniquet be exposed and clearly marked with its time of application.1
-
7Abdomen or chest. Exposed bowel: cover with a moist sterile dressing or the water-impermeable sheet, never force it back. Open chest wound: chest seal first; a sheet used instead is a non-vented seal — watch breathing and burp it if breathing worsens.1
-
8Reassess and keep them warm. Check circulation beyond the wrap and loosen it if it is cutting off a limb where no tourniquet is intended. Wrap the casualty against heat loss — burn casualties chill fast.1
Where it fits
- Dressing a traumatic amputation stump once the tourniquet is on1,7
- Burns — a large dry, sterile covering1,4
- Large pattern wounds: shrapnel, blast and wide abrasions across a back, chest or limb
- Covering exposed abdominal contents with the occlusive sheet1,3
- Controlling life-threatening limb bleeding — tourniquet first1
- Replacing packing in a deep or junctional wound — pack first, then cover
- An open chest wound when a chest seal is at hand — vented seal first1
- Covering a tourniquet — keep it exposed and marked1
- Reuse — single use only5
The evidence
The guidance and studies behind large-wound coverage and compression dressings — what each tested, and how strong it is.
| Study | Evidence type | What was studied | What it found |
|---|---|---|---|
| Riesberg et al., J Spec Oper Med 2021 | Expert review · guideline change | evidence-based systematic review of abdominal evisceration management, TCCC Guideline Change 20-02 | Cover exposed bowel with a moist sterile dressing or sterile water-impermeable covering; transparent covering preferred if bowel cannot be reduced |
| Naimer et al., Mil Med 2006 | Human · prospective field series | Elastic adhesive compression dressing over gauze, 62 consecutive bleeding wounds from penetrating trauma | Full bleeding control 87%, significantly reduced 11%; no significant complications; no comparison group |
| Charlton et al., Prehosp Emerg Care 2021 | Systematic review | 107 studies, 22,798 patients, of bleeding-control methods suitable for first aid providers | Direct manual compression reached hemostasis faster than pressure dressings or devices; very low certainty |
These sources address the jobs the BLAST does — covering eviscerated bowel and holding compression over a wound — not the BLAST Bandage itself. Its design rests on TacMed's patented amputation-dressing method.7
