TRACTION ELEVATOR MAINTENANCE - ATL
PERIODIC TRACTION ELEVATOR MAINTENANCE
General:
1. All wiring must be copper. Wiring must be installed in accordance with NFPA 70, these specifications and ASME 17.1. Wiring must be contiguous between terminal blocks, connection points on circuit boards and inside controller cabinets and junction boxes. Splices will not be allowed.
2. Use of any of the substances specified in these specifications or performing any of the operations specified herein must be conducted only in areas with adequate ventilation. The Contractor must provide temporary portable ventilation equipment as required to exhaust any fumes, gases, particulates, etc. generated by the use of the subject substances or performing the processes specified herein. The ventilation system must discharge the byproducts to a safe location outside the facility.
3. Workers that are using the substances or performing the operations specified herein must use Personal Protective Equipment (PPE) as required by FAA, OSHA, EOSH or other authority having jurisdiction.
4. If any substance requires ventilation as described above, air-monitoring equipment of an approved type must be furnished and employed by the Contractor to assure that the environment inside the facility is maintained in a safe condition for human occupancy. A baseline reading must be taken before any substance is brought into the facility. Air monitoring must continue for at least one (1) hour after completion of the task that required its use. If any detectable odors are observed, the monitoring and ventilation must continue for a minimum of one (1) hour after the odor is not detectable. If any adverse readings are noted, the ventilation and monitoring must continue for one (1) hour after the readings have returned to baseline values.
5. Use of any tools or equipment that are fueled by anything other than electricity is positively prohibited inside the facility. Hydraulically actuated tools and equipment will be permitted, provided that it is electrically or manually powered, or if the prime mover is located outside the facility a sufficient distance away to prevent any exhaust products from entering the facility.
6. Before any welding grinding, drilling, sawing, hammering or other noise and/or particulate and smoke generating operations are initiated, the Contractor must notify the COR and obtain permission to commence with said operations. An estimate of the duration of these operations must be given to the facility manager, so that AT can be notified. Should any of these operations interfere with the functioning of the facility or FAA personnel therein, the activities must cease immediately and measures taken and put in place to abate the interference to an acceptable level. Care and attention must be given to the possibility that the byproducts of said operations may interfere with the proper operation of sensitive FAA owned equipment, such as electronic devices, smoke detectors, heat detectors, etc. Care and attention must also be given to the possibility that said byproducts may migrate into areas where FAA personnel and equipment are located. Proper ventilation and containment measures must be in place before initiating any of the above-mentioned operations.
Soldering and Welding:
1. Solder must be a lead free type for any work on piping systems that convey liquids or gases. Solder for electrical/electronic connections must also be lead free, and must be the rosin core type unless a different type of solder or a different procedure is specifically called for by the manufacturer of the pieces to be joined. Mechanically clean all the surfaces to be soldered. (Submittal required)
2. Welding must be performed outside the facility to the maximum extent possible. Welds that cannot be accomplished outside the facility must be done during periods, as determined by the facility manager, that present the minimum possible exposure to FAA personnel and possibilities of disrupting the operations within the facility. A hot work permit will be required to be completed before any welding procedures will be allowed.
3. Proper ventilation and monitoring of the area must be in place as described above, before initiating these operations.
Painting, Gluing, Lubricating and Use Of Other Chemicals, Aerosols and Petroleum Products:
1. The use of paints, glues, adhesives, cleansers, lubricants, etc. must be minimized to the maximum extent possible. Particularly those that are sprayed or are aerosols must be limited to use in a well-ventilated area with proper containment. It is recognized that a substance may be perfectly safe, i.e. non-toxic, but may have an odor that is offensive or objectionable to some individuals. Therefore, these substances must be treated as if they were toxic or dangerous.
2. The Contractor must submit MSDS sheets for FAA review and approval in the first submittal package, and definitely before using any of the subject substances during the course of the work. These substances must be, to the maximum extent possible, volatile organic compound (VOC) free or at least very low in VOC’s. If products containing VOC’s are used, the Contractor must monitor the area with an approved monitoring instrument to ensure that the presence of VOC’s does not exceed recommended minimum threshold levels. Supplementary ventilation must be used as specified above.
Recommended Methods:
1. In lieu of using glues and mastics, the use of a combination of two-sided tapes such as 3M VHB or an approved substitution, and mechanical fasteners. Use of this method would particularly be applicable inside the elevator car.
2. In lieu of aerosol lubricants, cleansers, paints, etc., the use of brushes, wipes, or manually operated dispensers. Use of this method for degreasing, threading, cleaning, coating, and cutting would particularly be applicable.
Availability of Utilities and Storage:
Water, electricity, and sanitary facility are available for the contractor’s use, if available onsite. Telephone and internet services will not be available. At some sites, storage is limited to the machine room in contractor furnished metal locker or lockable boxes, at other sites there is no space for on-site storage.
