DO
NOT
The Occupational Safety and Health Administration (OSHA) requires, in addition to posting safety warnings
and barricading the work area (including, but not limited to, control room and testing bay), that the power
supply has been locked in the OFF position or disconnected. It is mandatory that an approved lockout
device is utilized. An example of a lockout device is illustrated in figure 2.1. The proper lockout procedure
requires that the person responsible for the repairs is the only person who has the ability to remove the
lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will
clearly note that repairs are under way and state who is responsible for the lockout condition. Tagout
devices have to be constructed and printed so that exposure to weather conditions, or wet and damp
locations, will not cause the tag to deteriorate or become unreadable.
Power Test does not recommend any particular lockout device, but recommends the utilization of an
OSHA approved device (refer to OSHA regulation 1910.147). Power Test also recommends the review and
implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These
regulations are available through OSHA publication 3120.
• Personnel should NOT be in the test cell during
operation and observation areas MUST be
constructed to protect personnel.
• Personnel and other equipment should be kept
clear of the drive shaft guard area and NEVER
cause an obstruction or block doorways.
!
CAUTION
The dynamometer is a tool. All personnel should
be kept clear of the area and only be in the test
area on a “need to be” basis.
IMPORTANT
When working with electrical or
electronic controls, make sure that
the power source has been locked
out and tagged out according to
OSHA regulations and approved
local electrical codes.
