Safety IV Catheter: Types, Specs and OSHA Rules

Who uses it: clinicians who place intravenous access, and the infection-control, safety and supply staff who choose and document the devices. A safety IV catheter (also called a safety IV cannula or safety catheter) is a short-term intravenous catheter with a built-in feature meant to reduce the risk of a needlestick injury. After reading, you should be able to tell what makes a device a “safety” device, read a federal device record, and name the OSHA and FDA rules that apply.

What a safety IV catheter is

A safety IV catheter is an intravascular catheter that includes a built-in safety mechanism for the needle used to place it. OSHA’s Bloodborne Pathogens standard (29 CFR 1910.1030) calls this category “sharps with engineered sharps injury protections”: a needle device “used for withdrawing body fluids, accessing a vein or artery” with “a built-in safety feature or mechanism that effectively reduces the risk of an exposure incident.”

The underlying device is regulated by FDA as an intravascular catheter under 21 CFR 880.5200: a slender tube and any necessary connecting fittings “inserted into the patient’s vascular system for short term use (less than 30 days) to sample blood, monitor blood pressure, or administer fluids intravenously.” FDA classifies it as Class II. In the openFDA classification database the product code is FOZ, “Catheter, Intravascular, Therapeutic, Short-Term Less Than 30 Days”, reviewed through the 510(k) pathway.

How the safety mechanism is built

Safety designs differ by manufacturer, so the generic answer is that the feature is built into the device and is meant to shield the needle after use. One manufacturer example: BD describes its Cathena Safety IV Catheter with BD Multiguard technology as a passive safety system that “automatically shields the needle as it is withdrawn”, and states the catheters are suitable for power injectors set to a maximum pressure of 325 psi (manufacturer claim, as stated on BD’s product page).

Passive and active designs

The BD wording above describes a passive design, where the shield engages as part of withdrawing the needle. Other products may require a separate action by the user; check each product’s instructions for use (IFU) for how its own mechanism works, since the mechanism is defined by the manufacturer, not by a common standard.

Types and sizes: what two federal device records show

FDA’s AccessGUDID database publishes the device identifier (DI) record each labeler submits. The two records below are both labeled as safety IV catheters; they illustrate how to read a record and are examples of two models, not a catalogue of the category.

Record field	BD Cathena Safety IV Catheter (DI 00382903868049)	BD Neoflon Pro Safety (DI 00382903916603)
Model	386804, 20G x 1.25 IN straight	391660, 24G x 0.75 IN straight
Catheter gauge	20 G	24 G
Length	32 mm	19 mm
Flow rate (as recorded)	60 mL/min	20 mL/min
Single use	Yes	Yes
Prescription use (Rx)	Yes	Yes
Labeled as containing natural rubber latex	No	No
MRI safety status	MR Conditional	MR Conditional

Source: AccessGUDID records, checked 2026-10-30. The key difference to notice is that gauge, length and flow rate are separate recorded attributes: a smaller gauge number means a larger catheter, and the two records here differ on all three. The generic IV catheter gauge selection guide covers gauge sizing in more detail.

OSHA and FDA rules that apply

• Engineering controls come first. 29 CFR 1910.1030(d)(2)(i): “Engineering and work practice controls shall be used to eliminate or minimize employee exposure.” Engineering controls “isolate or remove the bloodborne pathogens hazard from the workplace”, and OSHA’s examples include self-sheathing needles and safer medical devices.
• The exposure control plan must keep up with technology. Under (c)(1)(iv)(A) the plan must “reflect changes in technology that eliminate or reduce exposure”, and under (c)(1)(iv)(B) the employer must “document annually consideration and implementation of appropriate commercially available” and “effective safer medical devices”.
• Frontline staff must be asked. Under (c)(1)(v) employers must “solicit input from non-managerial employees responsible for direct patient care” when identifying, evaluating and selecting controls, and document that in the plan.
• FDA classification. The catheter itself is a Class II device under 21 CFR 880.5200 (product code FOZ).

The law that added the safer-device and frontline-input language to the standard is explained in the Needlestick Safety and Prevention Act guide, and record-keeping for injuries is covered in sharps injury log vs OSHA 300 log.

How to choose

The criteria OSHA itself states are the ones to start from: the device must have a built-in safety feature that effectively reduces exposure risk, the choice must be reviewed and documented at least annually, and employees who place and handle the devices must have input. Beyond that, the product’s IFU and device record define what a given model is: gauge, length, flow rate, single use, latex labeling and MRI status are all on the record shown above. The federal sources cited here do not rank one safety design above another.

Safe use and handling basics

• Follow the manufacturer’s IFU for the specific model; the safety mechanism works differently across products.
• The records above list both models as single use and prescription use (Rx), so a used device is not for reuse.
• The safety feature is one engineering control within a wider plan; OSHA also requires work practice controls alongside it.
• For the related closed-system device category, see closed IV catheter system; for the needle itself, see what is a hypodermic needle.

Common mistakes

• Treating the choice as a one-time purchase. OSHA expects the consideration of safer devices to be documented every year.
• Leaving frontline staff out. The standard names non-managerial patient-care employees as required contributors to device selection.
• Assuming one design stands for the category. The mechanism, materials and sizes are specific to each product and its IFU.
• Reading a shorthand size as the whole specification. Gauge, length and flow rate are separate attributes on the device record.

FAQ

What is a safety IV?

A safety IV is shorthand for a safety IV catheter: an intravenous catheter whose placement needle has a built-in safety feature that reduces the risk of a needlestick, which OSHA classes as a sharp with engineered sharps injury protection.

What is a safety IV cannula?

It is the same product class under a different name. “Cannula” is a common term for the catheter; FDA’s regulation 21 CFR 880.5200 uses “intravascular catheter”.

What does IV catheter safety involve?

At the device level, an engineered safety feature. At the program level, OSHA requires engineering and work practice controls, an exposure control plan reviewed annually for safer devices, and frontline input into selection.

What is a safety catheter?

Here, it means a catheter with an integrated needle-safety mechanism. For a particular model, its IFU describes how the mechanism operates.

Is a safety IV catheter required?

OSHA’s standard requires engineering controls and the annual documented consideration of commercially available, effective safer medical devices; it does not name a specific product.
