If there is an imminent danger, in addition to any other action you take, you should telephone OSHA. Your Right to An Inspection Often, OSHA prefers to investigate complaints by faxing a letter asking about the hazard to the employer, rather than by conducting an on-site inspection.
(November 2014) A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it.
Direct drive fan(s) moves large volumes of air uniformly. through entire condenser coil(s) for high refrigerant. cooling capacity. Upward discharge of air reduces operating sound levels. and prevents damage to lawns, shrubs, and walkways. Fan motors are totally enclosed, overload protected and. equipped with a rain shield. Fan service access is accomplished by removal of fan. guard(s) or removal of access panel.
