The following types of lockout devices are authorized for use at Michigan Technological
University:
Electrical disconnect or breaker lockout device - the switch lever must be
padlocked in the OFF position using a shackle and/or padlock with an identification
label.
Valve lockout device - may be locked out by using a padlock, a cable and lock,
or a valve handle lockout device. The method used is determined by the type of
valve.
Line blinds or "pancakes" - to isolate the time flow of fluid or gases in
piping systems. To be used in conjunction with pipe breaking procedures.
Multiple locks (gang hasp) - when more than one person or group has to work
on a machine, a lock adapter shall be used. Each person or group must place a
lock on the adapter, thus assuring each person a safe and complete lockout. It
is important that during a shift change, locks be left in place until the time
that the next crew is present and have placed their locks on the adapter.
