A vest is configured to serve as a portable lockout station, whereby maintenance workers may conveniently carry safety lockout padlocks (and their keys) and safety lockout tags from one maintenance location to another to allow them to impose a safety lockout on machinery when working on the machinery. The vest is preferably brightly colored and provided with reflective stripes so that it is readily visible to others around the maintenance location, and it includes pockets which are specially configured to complementarily fit safety lockout padlocks and tags for easy storage and access. The pockets are also formed of material which is at least partially transparent, such as mesh, and are placed on a location on the vest which is readily visible to the wearer such that the wearer can readily note when a safety lockout padlock is absent (e.g., when one has been forgotten at a prior maintenance location). The wearer of the vest is thereby encouraged to follow proper lockout procedures because lockout equipment is readily at hand, is maintained in an organized state, and is not easily forgotten when leaving one maintenance location to work at another location.
