here for short video "Tank Car Entering Collector Pans" (please allow sufficient time for video buffering) Federal EPA regulations, in particular 40 CFR 112, require that transfer of all oil products (including vegetable and animal) will be done over spill containments that have the capability of handling the full volume of the tankcar or other delivery vessel. The regulation does not say that this "full volume" containment must be immediately under the tankcar spur track and no rate of flow drainage from this collector is stated in the requirements. When evaluating track pans size and positions, the rate of flow from the actual collection pan to the "full volume" containment or the immediately adjacent track pans should be examined. Other manufacturers of open sheet track pans may use 1" NPT nipple and boiler nut interconnection methods. TESI uses the largest size available within the given height of the railroad rails. This is a minimum of 2" NPT and in the case of the end units, two, 3" NPT coupling hub are supplied at each end for drainage connection. |

In selecting track containment pans for
ethanol or other highly ignitable liquids loading or unloading, a number
of factors need to be considered. First of all, plastic or fiberglass
track pans age very quickly under sun UV exposure in about three to five
years. The ethanol only assists in the extraction of the "sticknosity"
of the fiberglass resins and the plastics. Another major safety consideration
is the fact that ethanol ignites easily and burns with a near invisible
flame. The local firefighters will tell you about its danger. For this
reason, the track pans and the tank car must be electro-statically
grounded to eliminate any spark opportunity. Trans Environmental
Systems, Inc, TESI, track pans are made of steel and have built-in
grounding lugs on both ends of each track pan for attaching to a grounding
grid. You'll want to check with local fire and electrical codes. Both
plastic and fiberglass are excellent insulators, not conductors, therefore
they cannot be grounded. If a track pan on which ethanol or other
ignitable chemical has been released starts to burn, and you have selected
cheap open plastic pans or FRP (fiber reinforced plastic-resin) pans,
the pans will burn up, too. With Trans Environmental Systems,
Inc. track pans with the rolling raincover, the fire dept. can just
roll the lid closed and extinguish the blaze quickly. Click

The slightly ridged, rolling lids on the
center pan are made of 3/16" diamond plate deck material and are
reinforced to support two people, yet they only require a few pounds of
pull to be opened. They can be locked in the closed position with lynch
pins, and can be opened completely for cleaning as needed. During inclement
weather they need only be opened immediately under the danger area. The
side pans have patented, hinged flip-flap lids that close over the pans
when not in use, which greatly reduces the amount of rainwater, snow and
debris that is collected. Once the tank car is chocked, the flip-flap
lids swing open to deflect any spills that might land upon the head of
the rails, or the small area between the track pans and the rails.
All assembly and mounting hardware is supplied.
The pans simply lag bolt down to existing railroad ties. It can be put
into service within a few hours of delivery and can be later relocated
by maintenance staff when plant operations change. Each unit is fabricated
to exact 'top of rail' measurement to provide the maximum self-containing
capacity yet remain safely within railroad safety clearance standards.

This
is our ultimate in spill containment for railroad tank car top loading
or unloading under pressure operations. This model comes with a center
pan that is positioned between the rails and two side pans immediately
outboard of the rails. When in the open position with the side pan flaps
extended, this model will protect an area 11 ft. 3-6 inches wide by either
10, 20, or 30 ft. in length. All pans have factory installed, plugged
NPT coupling hubs on the ends so that they can be piped to drain into
auxiliary large volume containment if required. When the two outboard
pans are piped together with the 20 ft. center pan, this system may self-contain
up to 500 gallons of liquid*.
