Boeing 727-200 Project Hazardous Materials Issues

12 September 1998: This page considers hazardous materials issues, and current management status. Hazardous materials include those which pose risks due to toxicity, fire, explosion, or environmental damage.

The Best Fluids Information I Have At This Time:

Direct data from Boeing:

Unconfirmed data, provided by Aero Controls:

There are no other fluids that I'm aware of.


Hazmat and Environmental Protection Management:

Hydraulic Fluids: A 47 gallon capacity absorbent mat in roll form (New Pig Company MAT230) will be available at all times, starting at Aero Air, and then, as soon as practical, placed in the aircraft cabin or a cargo hold for rapid access. Since the total hydraulic fluid capacity is reliably specified to be 33 gallons, this roll should be sufficient to handle any dry weather accident. On a dry weather day, the hydraulic fluids will be drained into secure containers using drain ports or by carefully cutting hydraulic lines at strategic locations. Plywood planks and a section of the absorbent mat will be placed underneath all drain points during all draining operations to insure that fluids can't reach the soil, and all draining operations will be executed and monitored by no less than two persons to insure an immediate and sufficient protective response should a draining operation deviate from normal.

Engine Oil: An identical strategy will be utilized to manage the draining of the engine oil (except that no cutting of oil lines is expected to be required).

Fuel: During the roughly 19 hour holdover at Aero Air, the fuel will be thoroughly removed from all tanks by Aero Air using one of their tanker trucks, and the tanks will then be inerted, probably by filling them with nitrogen. The slope of the ramp area to be utilized is such that a fuel spill would flow toward nearby turf, so a suitable supply of boxes of spill absorbent socks will be placed on the ramp, ready for immediate deployment in the event that any deviation from the expected defueling process occurs. Some preparation work remains: I need to acquire information from Boeing regarding options to the defueling port, whether that port is pressurizable, and to verify that the ports can be accessed from the front of the wing area (since the planned parking location for the aircraft prevents fuel truck access to the back of the wings).

Sewage Holding Tanks: As described above.

Turf Protection: Steel or heavy plywood planks will be located under the aircraft's landing gear tires at the Fair Complex work / display site to insure physical stability and partially reduce ground compression. Additional plywood planks will be utilized to protect the turf from biomass destruction due to human or support vehicle traffic where directed or agreed to by Washington County Fair Complex officials.
