ISO 23908: What Sharps Protection Features Must Do
A clinic that changes needle brands to save a few cents per unit can quietly change its injury risk. Safety features are not interchangeable, and the evidence for them is written down. ISO 23908 is the standard that describes how those features are specified and tested, which makes it the document a buyer should be able to name when a supplier claims a device is safer.
What the standard applies to
ISO 23908 covers sharps protection features on single-use hypodermic needles, catheter introducers and needles used for blood sampling. The scope is deliberately narrow, because the risk being managed is specific: an injury from a used needle after the procedure is finished, when attention has already moved on.
How a protection feature is described
- Passive designs that shield or retract without an extra action
- Active designs that need the user to engage the mechanism
- Needle-free or blunt alternatives for the same clinical task
- Blood sampling devices where the needle withdraws into a housing
The distinction between passive and active matters at a purchasing level, because the protection only exists when the action happens. A passive design depends on the device, while an active design depends on habit and training.
What the standard does not do
| Question | Where the answer lives |
|---|---|
| :-- | :-- |
| Is the safety feature effective? | ISO 23908 test methods and the supplier's report |
| Is the receiving container adequate? | Container requirements, and CSA Z316.6 in Canada |
| How is used waste streamed? | Provincial biomedical waste rules and facility policy |
| How is the device used correctly? | Manufacturer instructions and staff training |
Reading the table the other way is a common mistake. A container cannot compensate for a needle that was never shielded, and a shielded needle cannot fix a container that is overfilled.
Questions to put to a supplier
Ask which protection mechanism the product uses, what test evidence supports the claim, whether the device has been assessed against ISO 23908, and what the activation instructions say. Ask also whether the same gauge and length are available in the protected format, because a clinic that cannot get its usual size will keep the old product on the shelf.
Fitting this into Canadian practice
Canadian facilities layer three things: provincial biomedical waste rules, a container standard, and the device protection feature. For supplies, a one-quart sharps container with a locking closure (sharps container, 1 quart) suits treatment and blood draw rooms, protected blood sampling sets (winged infusion set, 23G) cover blood draws, and red biohazard bags (biohazard waste bags) close the blood-contaminated stream. Facilities reviewing a range of supplies can start with the wholesale account before ordering cases.

Frequently Asked Questions
What does ISO 23908 actually cover?
It sets requirements and test methods for sharps protection features on single-use hypodermic needles, introducers for catheters and needles used for blood sampling. In plain terms, it describes how a safety feature has to behave and how a manufacturer demonstrates that it does.
Does ISO 23908 replace a sharps container standard?
No. ISO 23908 deals with the protection feature on the needle or sampling device. The container that receives the used device is a separate product with its own requirements, and in Canada the CSA Z316.6 standard sits alongside that work.
How does a clinic verify a safety feature?
Ask the supplier for the test report that supports the protection claim, and for the instructions that state how the feature is activated. Then check that staff actually activate it. A feature that is never engaged gives the same protection as a plain needle.
What should a purchasing file contain for sharps products?
Keep the supplier's declaration of conformity or test summary, the activation instructions, the lot code of each delivery and the training record for staff. Those four items answer most audit questions.
