Cleaning Operating Room Lights: A Step-by-Step Disinfection Procedure

Why cleaning matters for lights above the field

Surgical lights sit directly over the patient, and in rooms with laminar airflow they sit in the cleanest zone of the theatre. Dust, aerosol deposits or dried splashes on the head, arm or handle can fall into the field or reach gloved hands. Cleaning and disinfection of the lights is therefore part of the standard room turnover and terminal clean.

Equipment design helps. A seamlessly closed housing with a smooth glass cover and few crevices is quick to wipe. SIMEON's HighLine, BusinessLine and examination lights use an aluminium body with the Anti.BAC antibacterial coating and scratch-resistant safety glass, and the Sim.LED 8000 has an IP54 housing. Lojer's Q-Flow 1 and 2 have a smooth, splash-proof IP44 light head. The coating supports hygiene but never replaces cleaning.

Before you start: safety and compatibility

Switch the light off and let the head cool. Never spray liquid directly onto the head, controls or arm joints, as fluid can enter seals, touch panels and electrical parts. Apply the agent to a lint-free cloth and wipe. Do not clean a light that is running or hot, and protect the cameras and monitor holders from liquid.

Check the manufacturer's instructions for use for approved disinfectants and the contact time. Some agents damage coatings, plastics, labels or glass, and abrasive pads scratch covers and can change the optical performance. If the instructions are not at hand, ask your supplier; do not guess.

• Switch off, let the light cool and, if required, isolate the supply
• Use a lint-free cloth and never spray directly onto the head
• Use only agents approved in the instructions for use
• Avoid abrasive pads, solvents and strong acids
• Protect cameras, touch panels and joints from liquid

Step-by-step cleaning procedure

Remove any sterile handle or cover first and send reusable handles for reprocessing. Wipe from top to bottom and from clean to dirty: arm, joints, head, glass cover and then the housing edges. Pay special attention to the handle area, the control panel and the underside of the head, where splashes collect. See surgical light handle covers for handle reprocessing.

Allow the disinfectant to remain wet for the contact time specified, then wipe with a cloth dampened with clean water if the instructions require it, and dry. Check that the light moves freely and that nothing is loose, and log the cleaning in the room record.

Frequency and special cases

Follow your infection control policy. A common pattern is to wipe handles and touched surfaces between cases, to clean the full light daily, and to include the arms and ceiling mount in the periodic terminal clean. After a visible contamination, such as blood splash, clean at once according to the spill procedure.

Mobile stands and examination lights in clinics should be wiped between patients, including wheels and the stand base. The Sim.LED 350 and other SIMEON examination lights are quick to wipe because of their seamlessly closed bodies. For the other maintenance tasks, see preventive maintenance of surgical lights.

Common mistakes and staff training

The most common mistakes are spraying liquid into the head, using the wrong disinfectant, scrubbing the glass with abrasives, forgetting the underside of the head, and cleaning a hot light. Another is leaving covers or handles on during cleaning, which traps contamination.

Train housekeeping and nursing staff together, put a one-page cleaning card near the light and review it when you change disinfectants or buy new lights. Beckfinity can provide the manufacturer's cleaning instructions for the SIMEON and Lojer lights you operate; contact our specialists for support.
