10.2.21.2 Inspections Made with Power On. Close the mainline switch and proceed to observe
the operation of the control equipment when the manlift is running. Note any arcing of contacts,
excessive heating of coils or resistances, and misalignment of relays, contactors, and switches.
Manlift speed must also be checked and compared with previous test data and criteria. The speed
is checked with a hand held tachometer with its drive wheel directly engaging the moving belt.
This will determine if the system is operating at its full potential or if adjustments are needed to
obtain a system operating at design capabilities. Unusual noises should also be noted.
10.2.22 Machinery Area
10.2.22.1 Illumination. Check the machinery area for adequate lighting.
10.2.22.2 Housekeeping. Check the machinery area for housekeeping and the presence of any
flammable liquids (flash point less than 110 degrees F) or materials not necessary for the
operation and maintenance of the manlift.
10.2.22.3 Ventilation. Check that the machinery area has been provided adequate ventilation by
natural or mechanical means to ensure safe and normal operation of the manlift. Check local
codes to see that machine ventilation is in compliance.
10.2.22.4 Fire Extinguisher. Check the machinery area for fire extinguisher, proper class,
mounting, and maintenance record tag. They should be properly mounted and maintained.
10.2.23 Machinery Area Access
Check that a permanent, safe, and convenient means of access to machinery spaces has been
provided and maintained. Check stairways and ladders to see that they are stable and secure.
Also check to see that the access is not infringed on by building changes. A prime example is air
conditioning being added: the contractor installs a large duct right through the access right of
way, requiring the person who enters the space to crawl under the duct. Public safety may be
directly dependent on rescue personnel getting to the manlift equipment in a hurry. The access
door should be self-closing, self-locking and maintained in the closed position. In addition, Navy
policy is that the machinery spaces are considered to be controlled access areas, to be secured by
lock and key or combination locks.
