First Aid Only 4-001 Large Sterile Triangular Bandage

First Aid Only 4-001 Triangular Bandage — the sling, splint-tie, and wrap multi-tool

If your kit is missing a triangular bandage, you're missing a required ANSI/ISEA Z308.1 fill item and one of the most versatile pieces of fabric in first aid. The First Aid Only 4-001 Large Sterile Triangular Bandage is sized 40 x 56 inches — the standard reference dimension — and folds into an arm sling, ties a splint in place, or wraps a large wound. This page covers what's in the package, how it compares to other bandages in the bandages and wound care collection, and what to order alongside it.

First Aid Only 4-001 Large Sterile Triangular Bandage is a 40 x 56 inch sterile triangular fold of fabric used to make an arm sling, secure a splint, or cover a large wound when a standard bandage or pad isn't big enough.

Key features

• Standard 40 x 56 inch size matches first aid and wilderness medicine training — no improvising the fold
• Sterile packaging allows direct contact with an open wound, not just outer-wrap use
• Folds into an arm sling for shoulder, forearm, and wrist injuries
• Ties down a rigid splint once it's molded around a wrist, ankle, or forearm
• Opens flat to cover a large laceration or burn area a standard pad can't reach
• Required item in ANSI/ISEA Z308.1-2021 Class A and B kit fills

Specifications

Use cases

• Arm and shoulder slings for suspected fractures, sprains, or dislocations while awaiting further care.
• Splint tie-downs when used alongside a rigid splint like the SAM Medical SAM Splint Medium to hold it in place around a wrist or ankle.
• Large wound coverings for lacerations or burns that exceed the size of a standard adhesive bandage or gauze pad.
• ANSI Z308.1 fill compliance for any workplace first aid kit that requires a triangular bandage as a stocked item.

Compatibility: what to stock alongside this bandage

A triangular bandage does its best work paired with a few other items. For splinting, add the SAM Medical SAM Splint Medium as the rigid support the bandage ties down. For smaller wraps and securing dressings without adhesive, the AZEN Self-Adhesive Cohesive Bandage Wrap covers jobs where a full triangular bandage would be oversized. Prep the skin around any wound first with a Curad Alcohol Prep Pad, and keep a McKesson Instant Cold Pack nearby since sprains and fractures that need a sling usually also need cold therapy.

What this bandage is not: it is not a bleeding-control dressing — for significant bleeding, use a dedicated compression bandage or tourniquet from the Trauma Kits & Bleeding Control collection, not this item.

For a full kit build, cross-shop the first aid kit refills collection so bandages, splints, and wraps get restocked on the same schedule.

Comparison: triangular bandage vs other wraps on WC Safety

The triangular bandage's job — slings and large wraps — doesn't overlap much with the rest of the wound-care lineup, but here's how it stacks up against the closest alternatives:

• Choose the triangular bandage when you need a sling, a splint tie, or a large wrap in one item.
• Choose the AZEN cohesive bandage wrap for securing a dressing or compressing a sprain without adhesive residue.
• Choose the Healqu island dressing when the wound itself — not the surrounding limb — needs a larger sterile pad.

Frequently asked questions

How many triangular bandages should I order per kit?

Order at least two or three per kit — one for a sling, one for a splint tie, and a spare — since a single unit runs out fast once you use it for one purpose. At $4.81 each, stocking multiples is inexpensive.

Is this the right size to match my first aid training?

Yes — 40 x 56 inches is the standard size referenced across most first aid and wilderness medicine courses, so the folds and knots you were taught will apply directly to this bandage.

Does this bandage ship sterile or just clean?

It ships sterile and individually packaged, which means it's safe to use directly against an open wound, not only as an outer wrap over an existing dressing.

What size kit or cabinet does this bandage belong in?

It fits any ANSI Class A or Class B kit, from a small vehicle first aid kit to a full first aid cabinet — see the pillar guide which first aid kit do you need guide to size the container first.

Should I buy the triangular bandage or the AZEN cohesive wrap first?

If you're stocking a kit from scratch, get both — the triangular bandage is a required ANSI fill item, and the AZEN cohesive bandage wrap handles smaller securing jobs the triangular bandage is too bulky for.

Does this bandage come with instructions for making a sling?

No printed folding instructions are included in the package; the assumption is buyer familiarity from first aid training. Keep a laminated first aid reference card in the kit if your team hasn't been trained.

Can I use this bandage for a snake bite or burn wrap?

It can serve as an improvised large-area wrap or covering, but follow current first aid guidance for the specific injury type rather than treating this as instructional content — the bandage is a supply item, not a treatment protocol.

Is a triangular bandage required for OSHA compliance?

OSHA 29 CFR 1910.151 references ANSI/ISEA Z308.1 for kit contents, and Z308.1-2021 lists a sterile triangular bandage as a required Class A and Class B fill item — see the OSHA first aid kit requirements reference for the full breakdown.

What splint pairs with this bandage for a wrist or ankle injury?

The SAM Medical SAM Splint Medium molds around the joint and the triangular bandage ties it in place — the two are commonly ordered together for field and trail kits.

Does this bandage expire?

Follow the printed lot or use-by date on the sterile packaging, and rotate stock so older units get used first during routine kit audits, the same as any sterile dressing.

Can I order a bulk quantity for a fleet of vehicle kits?

Yes — order multiples of this single-unit item, or cross-shop a structured refill from the first aid kit refills collection that already bundles a triangular bandage with other required items.

Is this bandage waterproof or reusable?

It's a fabric bandage, not a waterproof or reusable product — treat it as single-use once removed from sterile packaging, and replace it after use rather than attempting to re-sterilize it.
