Is it difficult to install a HoldSafe Unit?


  • Installation for external units can typically be completed by a general facilities management or maintenance individual with moderate technical skills. There is no wiring required, just alignment, placement and securing screws.
  • We estimate the installation time to be under an hour per unit. There are a few steps that require a second set of hands to ensure even alignment. We have a detailed instruction manual that is included with each unit. We can also supply an installation jig that allows single person installation, we recommend this for large scale installations. Please contact us for further information
  • Internal units will require qualified escaltor technicians. Your local codes and regulations will indicate your requirements.
However, local city, state, or regional codes vary. Please verify with your regional authority, or equipment maintenance contractor.




How long does it take to install a HoldSafe UV Handrail Disinfection Unit?


  • We have estimated 45-60 minutes per unit.
  • This is a conservative estimate and with experience and planning we have seen this time below 40 minutes each unit. With 2 technicians working in tandem, time is greatly reduced.
  • These estimates are for a glass balustrade walkway or escalator, times will differ slightly for other variants, however the general process is the same.




Is there a risk of fingers being caught or pinched in the external units?


  • No. We engaged with UL to obtain our North American safety certification to eliminate any risk to the public. UL writes the standards for safety in almost all commercial and industrial product applications, and tests products extensively to ensure compliance.
  • We worked with UL to produce a set of safety guards with brushes in order to address the potential issue of pinch points and entrapment. The brushes act as a prompt and are fitted above and below the unit, and the guards minimize the gap to the handrail to within those deemed safe by UL.
  • The guards also create a safe distance from any entry point to an internal moving part – therefore avoiding any exceptional risk for pinch points.




Is there a risk of UV-C ultraviolet light harming the public?


  • There is no risk of UV light escaping the unit or creating unsafe exposure to the public. The HoldSafe unit uses UV-C LED light modules that are fully contained within the enclosure.
  • UV-C light is only exposed on the handrail within the unit. There is a non-UV blue indication lamp on the face plate of the external units to indicate that it is in operation.
  • The risk of UV irradiance (UV light escaping) was also tested and passed by UL for the external units.




What happens in the event the handrail shuts down?


  • The self-generating units have a built-in low voltage electricity generator and are entirely self-powered using the motion of the handrail. (no wiring required during installation)
  • If the handrail is shut down the units do not operate. It will immediately restart once the handrail is restarted. There is no battery or high capacity capacitor in the UV unit. There is no risk that it will operate during maintenance or other stoppage.
  • All units cannot function if removed from an operating handrail. Escalator shut-off is required for maintenance of the internal units.




Will HoldSafe damage the escalator?


  • No, there is no risk of any damage to the escalator. The external units do not require any hard wiring during installation or disassembly of the installed escalator/walkway. There is no alteration to the exisiting equipment.
  • The internal units are mounted using a bracket that can be removed and moved as required.




Will the UV light damage the handrail?


  • There is no evidence of any short-term or long-term damage to a handrail from UV-C light
  • In general, UV-C light is less harsh than chemical based cleaning products.
  • The handrail is exposed to the UVC rays for 0.2 to 0.4 seconds for each cycle (1 time of cycling) so there is no prolonged exposure on any given point on the handrail
  • The UV-C will be absorbed primarily by the surface bacteria and pathogens present on a handrail
  • We have units that have been installed over a 3 year period showing no evidence of damage to the handrail




Are there any parts that require service or regular replacement?


Yes, these are the Maintenance Recommendations: REGULAR (External Units)

  • It is recommended to utilize compressed air to dislodge any dust build up in the interior of the unit on a regular basis
  • Dependant on the usage and location of the escalator or walkway, this could be daily, weekly or monthly
  • Simply direct the compressed air nozzle into the TOP and BOTTOM guards to blow out accumulated dust. A 5-10 second application of compressed air is sufficient
  • If something has become lodged within the unit, remove the side covers to gain access to the inside of the unit. Ensure the handrail is NOT moving. An item can be dislodged accordingly. Ensure the side covers are replaced securely and correctly
  • Never operate the unit without the side covers
PERIODIC (All HoldSafe Units)
  • The UV-C LEDs are rated for 10,000 hours of lifetime before they degrade below the guaranteed effectiveness level
  • The self-powering generator has a rubber roller that may show wear and tear based on usage conditions
  • PürHealth Recommends replacement of both components at the same time. We suggest referencing 10,000 hours as the lifespan to calculate when the units need servicing. Average Replacement cycle can vary from 1.5 to 3 years based on system operation
  • Note: A system operating 24/7 will require replacement in 13-14 months
  • Periodic maintenance requires a trained technician or a factory refurbishment. Please contact PürHealth for options info@purhelath.ca
