Manual Pull Stations

Documented below is the photographic record of manual pull station inspections.  MPS inspections are covered under NFPA 72 (and other standards).  Miscellaneous storage blocking access to MPS are the most common deficiency observed.  Occasionally, however, the devices will not work or are not properly attached to structure.

Photo below shows a MPS partially detached from structure.  Occupancy is a multi-story apartment complex.

Next photo shows a MPS partially obstructed by fire sprinkler standpipe system:

Next we have a well marked out of service call box:

Next we have an indoor MPS obstructed by miscellaneous storage:

Another view:

Next we have a MPS (sometimes called a "call point") station showing improper repair.  The glass is fractured and it is cracked. 

An investigation later showed damage was caused by "horse play", however, the non-standard repair was done with clear plastic tape.

Next photo shows the improper repair in more detail:

Additional pieces were found incorrectly repaired with "tape":

Next series of photos show a MPS detached from structure.  Note the missing clamp on the vertical conduit.
