Weather Factors Into Frequency of Door Hardware Inspections
Weather is also a factor to consider when deciding on the frequency of inspection, especially for the side of the building most exposed to the elements. Driving rain, snow and ice buildup can make the best door hardware balky. On the other hand, while the same frequency of inspection would not apply to an emergency exit, it is just as important to schedule regular checks to ensure emergency-exit hardware operates reliably in a crisis.
Maintenance. A list of maintenance instructions should be easily accessible. For example, here is a list of recommended actions for an upgrade of a commercial torsion spring overhead door and hardware:
- Check moving parts, such as cables, for signs of wear.
- Lubricate moving parts, and coat torsion springs with regular grade machine oil or lithium-based grease for wet conditions.
- Check door and track supports for proper spacing and alignment.
- Check door balance by disconnecting the operator, opening the door partially, and checking too see if it stays stationary.
- Check the seal at the header, jambs and floor for air leaks, and adjust as needed.
- Check the manual to be certain all safety labels are in place and legible.
Managers also should ensure technicians follow an approval process. They should submit completed checklists, recommended inspection processes, specification sheets, and operation and maintenance manuals to a subject matter expert, architect or engineer who has the final approval regarding the correctness of installation. This process ensures doors and hardware meet specification standards and that technicians follow procedures for long-term reliability.
