Pipe Support

The following photos show pipe supports.

It is assumed in inspections that pipe supports have been approved.  Pipe supports do not require to be listed.  The following must have been approved:

The next photo shows another seemingly approved installation.  The SLR ratio is?

Another approved install:

A small anti-freeze system is shown below:

The next two (2) photos show another install:

Another small install:

The photo below shows ATR under non-axial loading. Not a deficiency.

Duct Detectors

The following photo shows a horizontally mounted duct detector under going inspection:

Pipe (Condition, Differential Movement)

Below a photograph shows possible differential ground movement and resulting damage to supports for an above ground heat traced insulated water supply:

Another view:

Another location on this feed shows another support strap failure:

Photo below shows missing bolts:

More missing bolts:

Another support disconnected:

On Dry Chemical Systems

The following photo shows a dry chemical overhead piping system:

The following photo shows a pneumatic actuator to dry chemical (Foray) storage tanks (system is undergoing inspection):

Below, a photo shows tanks being disconnected and removed for inspection:

Another photo showing on going inspection:

Initiating Panel undergoing inspection:
Below, a photo shows recently inspected (and weighted) nitrogen cylinders used to trip various dry chemical systems:

Dry Chemical Nozzle is shown (visual inspection being conducted, blow off cap removed):

Photo below shows a normal pneumatic actuator:

The next three (3) photos show a pneumatic actuator (removed from a 1,500# Foray system) removed from service.  The actuator is in a non-normal condition. 

The next photo shows a side view of the actuator:

Below a photo shows a CO-2 high pressure switch main/reserve switch in the reserve position.  The reason is unknown.

Another CO-2 system with reserve switch engaged:

Below a photo of a CO-2 releasing pull station.  Notice the contradictory signage:

Below, a photo shows a LED indicating a CO-2 system in maintenance mode:
The following photo shows a diesel generator room protected by a zoned CO-2 system.  The fire door is incorrectly propped open.

Below, the exterior of an electronics cabinet for a satellite earth station is shown.  An exterior heat exhaust louver is shown.  Often these do not close on CO-2 (or other clean agent activation):

On test of a clean agent (FE-13) system the louver pictured below did not close:

Another louver in the same protected cabinet/space:

The next photo shows a motorized louver in a CO2 protected satellite earth station, the louver did not close on system activation:

The following photo shows the relay inside the releasing panel that controls the above mentioned louver:
Not all systems have electrical maintenance switches.  Photographed below is a maintenance switch on a clean agent system.  The maintenance switch is in the armed position:
The following photograph shows two (2) CO-2 control modules removed for testing. Note, the control modules are not supervised:

The following photo shows a CO-2 Kidde-Fenwal control module solenoid activated (from testing):

The photo below shows two (2) CO-2 cylinders.  They were last weighted in 2014.  The photo was taken in Spring 2016:

The following shows a door on a CO-2 protected space (diesel generator, not pictured).  This inspector is unaware if calculations and/or a fan test was performed to verify the door leakage will not adversely affect the CO-2 system's performance:

Photographed below ("blue box") is a CO-2 protected diesel generator.  A cross-zoned fire alarm & releasing system is also installed.  Central station service is provided by a 1W VHF radio network, the F/A radio antenna (to the upper right of the door) can be seen on the front of the blue conex box:

Photographed below is a diesel generator protected by a single bottle high pressure cross-zoned CO-2 system.

The photo below shows the diesel fuel shut off solenoid and ball valve that should be activated on a cross-zone fire detection signal.  Note the ball valve handle is partially obstructed by the piping:

A close up of the diesel fuel shut off valve is below.  Note the handle/pipe mechanical interference.

The photo below shows a high pressure CO-2 bottle about to get weighed:

Photograph below shows the above bottle's gross weight being measured:

Photo below shows a fractured CO-2 discharge indicator.  Note the other indicator in the distance.

The following photo shows a CO-2 rack.  Arrow points to a nut nit fully tightened:
