Building a Laser Safety Program for Your Med Spa: LSO, Eyewear & Documentation

Most conversations about buying an aesthetic device focus on wavelengths, treatment menu, and return on investment. The part that gets planned last — and occasionally not at all — is the safety program that has to exist around the device once it is on the floor. Nearly every aesthetic laser sold today is a Class 3B or Class 4 system, and that classification is what brings a formal program into scope. The requirements are well defined, largely one-time to set up, and mostly a matter of assigning responsibility and keeping records.

The standard behind the requirements

ANSI Z136.3 is the laser safety standard written specifically for health care environments, and it is the framework most medical spas, dermatology practices, and surgical centers reference. It is a consensus standard rather than a statute, but OSHA enforces it by reference under workplace safety rules, and it is widely treated as the benchmark for reasonable practice. Layered on top of that, individual states set their own rules about who may operate an aesthetic laser and what level of physician supervision or delegation is required — and those rules vary widely enough that a protocol written for one state may not satisfy another.

The practical implication for a practice owner is that there are two separate questions to answer, and answering one does not answer the other. The first is technical: is the device being operated safely. The second is regulatory: is this person, in this state, permitted to operate it at all.

Designating a Laser Safety Officer

Facilities operating Class 3B or Class 4 lasers are expected to designate a Laser Safety Officer. In a large hospital that is a dedicated role; in a med spa it is usually an experienced clinical staff member who takes the responsibility on alongside their treatment work. What matters is that the role is named, documented, and backed by actual authority to stop a treatment.

Maintain the device inventory, including classification and wavelengths for each system on the floor.
Establish and post the nominal hazard zone for each treatment room.
Verify that protective eyewear on hand matches every wavelength in use, and that it is inspected and replaced when damaged.
Approve standard operating procedures for each device and confirm operators are trained on them.
Keep training, service, and incident records current and retrievable.
Hold the authority to suspend use of a device pending service or retraining.

Eyewear is chosen by wavelength, not by device

This is the single most common gap in practices running more than one platform. Protective eyewear is rated for specific wavelength ranges at a specific optical density, and eyewear that protects against one wavelength may offer no meaningful protection against another. A room where two different systems are used needs eyewear appropriate to each, and the operator has to know which pair goes with which handpiece rather than reaching for whatever is on the counter.

Multi-wavelength platforms make this concrete. SANDRO DUAL delivers 755 nm and 1064 nm, V-LASER combines 532 nm KTP with 1064 nm Nd:YAG, PASTELLE PRO and PICO MAJESTY both run dual 1064 nm and 532 nm, and PICO ALEX adds 755 nm. A practice running several of these is covering three distinct wavelength bands, and the eyewear inventory has to reflect that.

Confirm the optical density rating covers every wavelength the device emits, including the aiming beam where applicable.
Count the pairs: everyone inside the hazard zone needs protection, not just the operator.
Plan for patient eye protection separately — external shields or intraocular shields depending on the treatment area.
Inspect for scratches, pitting, and delamination on a set schedule; damaged eyewear is not rated eyewear.
Higher optical density generally means lower visible light transmission, so factor room lighting into the selection.

Controlling the treatment room

The nominal hazard zone is the area in which exposure could exceed safe limits, and it drives most of the room controls. Access to that zone has to be managed while the device is in use, which in practice means a door that latches, warning signage posted at the entrance, and a rule that staff do not walk in mid-treatment. Windows need covering appropriate to the wavelength. Highly reflective surfaces and instruments are worth reviewing, since a specular reflection carries the same energy as the beam.

Laser-in-use signage at every entrance to the nominal hazard zone, specific to the class and wavelength.
Controlled entry while the system is keyed on, with the key removed and stored when it is not.
Window coverings rated for the wavelengths in use.
Smoke and plume evacuation for any procedure that generates it, positioned close to the treatment site.
Awareness of flammable prep solutions, alcohol, and supplemental oxygen near an active Class 4 beam.

Documentation is the part that gets audited

A safety program that exists in practice but not on paper is difficult to demonstrate after the fact, and the record request usually arrives at the least convenient moment. The documents themselves are straightforward, and most of them are generated naturally in the course of operating the device — the discipline is in filing them consistently.

Written LSO designation, with the date and the scope of the role.
Device-specific standard operating procedures, including startup checks and parameter ranges.
Operator training records: initial manufacturer training, competency sign-off, and any refresher training.
Service, calibration, and repair history for each system — keep the vendor service reports rather than relying on memory.
Treatment records showing device, wavelength, and settings used for each session.
An incident and near-miss log, even when nothing came of the event.

When evaluating a vendor, it is worth asking how training and service documentation is handled, since those records become part of the practice compliance file. A platform that is well supported produces a clean paper trail almost as a side effect; one that is not tends to leave gaps exactly where an auditor looks first.

Radiofrequency sits under a different set of rules

Radiofrequency systems are not light-emitting devices, so laser classification, optical density eyewear, and nominal hazard zones do not apply to them in the same way. OLIGIO X, WONTECH's next-generation monopolar RF platform, and OLIGIO, the established system in the same family, both use advanced monopolar radiofrequency technology rather than a laser source. That does not put an RF platform outside the safety program — it means it belongs in a different section of it.

Electrical safety and correct return electrode or grounding pad placement per the manufacturer instructions.
Operator training and competency documentation, exactly as with a laser platform.
State scope-of-practice rules, which frequently cover energy-based devices broadly rather than lasers specifically.
The same service and treatment record keeping applied to every other system on the floor.

Fold it into the device installation

The cleanest time to build all of this is the week a new platform arrives, while manufacturer training is already scheduled and the clinical team is focused on the device. A short checklist at install prevents the more common alternative, which is discovering a gap six months later during an inspection or an insurance review.

Add the new system to the device inventory with its class and every wavelength it emits.
Order eyewear for those wavelengths before the first patient, in the quantity the room requires.
Write the standard operating procedure while the trainer is still on site.
Post signage and confirm the room controls for the nominal hazard zone.
Have every operator sign off on training, and file the certificates.
Confirm with your state board, and with counsel where the answer is not obvious, who is permitted to operate the device and under what supervision.

Requirements differ by state and change over time, so verify the specifics for your jurisdiction. If you are planning a new platform and want to talk through training, service support, and what the install week looks like, a demo with your clinical team is the best next step.
