Gauze, Non-Adherent Pads, Abdominal Pads and Medical Tape Explained
First-aid dressings are not interchangeable. Gauze pads can clean, cover or absorb; non-adherent pads are designed to reduce sticking; abdominal pads provide larger absorbent coverage; rolled gauze helps secure a dressing; and medical tape holds materials in place. Choose by the wound, required absorbency and first-aid training.

Key takeaways
- Keep sterile dressings sealed until needed and inspect packaging during restocking.
- Size and absorbency should suit the likely first-aid scenario.
- When bleeding is severe, embedded objects are present or the injury is serious, seek emergency medical help.
What does each first-aid dressing do?
| Supply | Typical function | Selection consideration |
|---|---|---|
| Sterile gauze pad | Covers or absorbs; may also be used as trained for cleaning | Dimensions, ply, sterility and absorbency |
| Non-adherent pad | Contact layer intended to reduce sticking | Wound type, size and whether a secondary absorbent layer is needed |
| Abdominal pad | Large, absorbent dressing | Coverage, absorbency and securement method |
| Rolled gauze | Wraps or secures a primary dressing | Width, stretch and avoiding excessive pressure |
| Medical tape | Secures dressings or tubing as intended | Adhesion, skin sensitivity, width and removal |
How should a workplace choose dressing sizes?
Stock a practical range based on the workplace first-aid assessment, the number of workers and the types of injuries that could reasonably occur. A dressing should cover the intended area without forcing staff to improvise with multiple unsuitable pieces. Provincial and territorial first-aid-kit requirements can differ, so verify the rules for each location.
What should be checked when restocking?
- Compare inventory with the workplace's required kit list.
- Inspect seals, packaging integrity and any labelled expiry or best-before information.
- Remove wet, crushed, opened, contaminated or damaged packages.
- Rotate older usable stock to the front without concealing dates or condition.
- Confirm scissors, gloves, tape and other supporting items are present.
- Record the inspection and replenish to the established minimum quantity.
Frequently asked questions
Is all gauze sterile?
No. Verify the individual product label and packaging. Do not describe or use an item as sterile unless it is supplied and maintained that way.
Does a non-adherent pad absorb as much as an abdominal pad?
Not necessarily. Products are designed for different roles; a non-adherent contact layer may require a separate absorbent secondary dressing.
Can tape go directly over an open wound?
Use products only as labelled and trained. Medical tape is generally used to secure a suitable dressing rather than substitute for one.
When should emergency help be sought?
Call emergency services for severe or uncontrolled bleeding, major trauma, breathing difficulty, loss of consciousness or whenever the situation may be life-threatening.
Shop gauze and bandages, medical tape and first-aid and safety supplies. See the workplace first-aid restocking guide for a broader inventory process.
