The 1st floor Burn Cell in the STU has bee refit with full wrap around stainless steel trims on all doors and shutters Training maintain 800 degree fire operations try to not exceed 1000 degree flame impingement for any longer than 5 minute. I've attached the required matrix for the marinite liner system

I was task to troubleshoot the vent system in the burn cell Troubleshooting found two issues

1) The power supply was damaged and not powering

up. WRG replaced the Sola 24 volt power supply.

2) The AD drive needed to be reprogrammed which was done.

3) The Watlow pyrometers needed the terminal connections removed and cleaned which was done.

4) The Watlow pyrometer needed reprogramming which was done.

5) The Operation switch was damaged and replaced System is functional now and recommended that the power supply remain on at all times.

I was task to upgrade the 3-2600 PSI rappelling anchors to 5000 PSI per NFPA. To do this the requirement was to move the existing eyelets to a structural member. In doing so the eyelets which where rated had to have extensions added. Shown here is the completed installation.

Note the locking nuts which secures all movement. These require an annual inspection. The old holes have been covered using enamel coated 3 piece gasket seal offs.

One additional concern is the arch shown here. This is not rated as an anchorage point. If using as a transition tie back the arch to the rated anchors.

I suggest budgeting for a rated arch. These are built and installed to 9000PSI.

One of the troubleshooting issues I was tasked to work through was slow reclamation in the pond.

The system was set up to reclaim the pit water at 500-750 GPM. And the apparatus has the ability to apply close to 1000GPM so it is important for the system to be working in order to have safe and effective training evolutions.

For the system to provide 500-750GPM it requires 4 things to be in perfect running order.

1) The pond must be pumped down so that the top of the pump motor and approximately 6 inches is exposed. The higher the pond water elevation the slower the transfer of water.

(The drain piping is only installed at an 1/8 inch per foot fall to the pond)

2) The pit weir drain valves must be wide open (2 valves in and out)

3) 3) The weir itself must be free of debris to allow maximum flow through the screen

4) 4) The piping from the Weir to the pond needs to be cleaned at least once every two years using high pressure water / Vetter rooter. Currently there is about a quarter of the pipe blocked with debris and algae growth. This is slowing the transfer as the water seeks its own level within the pipe and pond. The cleaner the pipe the faster the transfer.

Pond Water Quality is very important. The more algae spore in the pond the more algae growth we will have to deal with in the Pit, Pump, Weir and piping systems.

Currently there is about 6 inches of bottom growth / debris in the pond.

The pump was running slow and even had plugged the screen during our pump off of the pond.

(Note never run the pump to the pit water system without the screen installed this will avertedly plug up the water jackets and sprinklers with debris. The pump will move the solids up to 2 inches through the piping systems but it will plug downstream.)

We recommend the pond aerator run continuously and that aqua shade be incorporated at a rate of one gallon every 60 days. The pond should be cleaned every three years or as needed.

The next slide shows damage to the pond liner system

As we were pumping the pond we noticed a large amount of trapped water in between the dual liner system. I suspected damage but could not locate until the pumping off brought the level down enough to expose the damage.

I this slide I want to point out 2 conditions

1) The pump pad (concrete) has been slid away from the pump in an effort to expose the intake cavity under the pump. I suspect to increase pump flows. However in doing so the concrete was slid off the HDPE blanket protecting the HDPE pond liner. I have identified damage to the pond liner in this position.

2) The weight and age of the HDPE liner may had both contributed to the weld failures in one corner identified in the next slide. The failure has exposed a large separation approximately 12 inches long. Allowing water to transfer between the liners.

The damage to the HDPE is repairable but will require

1) The pond to be completely cleaned of debris. And liner 2nd containment pumped.

2) The pump and concrete pads to be removed. Only one pad needs to be reinstalled.

3) The liner to be steam pressure washed

4) The liner to be thoroughly inspected for other damaged areas

5) HDPE welder on site

6) Cut out of damaged areas / welds as needed

7) Welding repairs made (requires outside temperature to be 60 – 80 degrees)

This is a 4 to 5 day process and will Require 3 men to accomplish.
