UER Forum > Archived UE Main > Asbestos in Storm Drains (Viewed 137 times) F A S T  Location: Oakland, CA Gender: Male Coastal Wind  |  |  |  Asbestos in Storm Drains < on 10/12/2003 7:42 PM >   http://www2.faa.gov/arp/engineering/briefs/eb10.htm What I took in: "Date: January 13, 1976 In Reply Refer To: AAS-580 Subject: Engineering Brief No. 10, Asbestos-Cement Storm Drain Pipe From: Chief, Airports Engineering Division, AAS-500 To: All Regions Attn: Chiefs, Airports Divisions Engineering Brief No. 10, Asbestos-Cement Storm Drain Pipe, presents the ASTM and AASHTO specifications which should be used for storm drain pipe instead of Federal Specification 55-P-331 (see Division IV, Drainage, 701-2.9 of Advisory Circular 150/5370-10)." I was under the distinct impression that asbestos pertained to insulation. Why would they use asbestos in a storm drain? Or have I completely misinterprated this 'brief.' The link is at the top if you want to check out the whole thing. Anyone know anything about the normality of asbestos in storm drains. I'm inclined to think it would be rare.

Type II ...", and to prevent the buildup of H2S - "In cases Where the generation of hydrogen sulfide cannot be controlled by design, the use of asbestos-cement pipe with lining conforming to ASTM C541 should be considered." Whoever wrote this report obviously did not spell-check, or reread it, becouse their are many spelling errors, "Type II pipe is intended for use whore", great... I would not be too worried about running across asbestos sewers, becouse it would appear their use is only for special applications, and if in one, I would be more worried by what it was carrying, then the asbestos.

They quantity, condition, and type of asbestos is important in determining what danger exists, if any at all. Chyrsotile asbestos makes up the vast majority of asbestos used in this country, and there is strong evidence to suggest that even when inhaled in large quantities, it is not detrmimental to your health. Even crocidolite asbestos, which has been shown to cause lung cancer, is not a hazard to your health unless inhaled, and even then it is accepted that you would have to breath large quantities of this stuff. Simply having it used in the manufacture of a product does not immediately classify that product as legitimately dangerous; the asbestos may be firmly locked within the makeup of the material and may never be released into the air in sufficient quantities to be considered even remotely hazardous. Macsbug hit the nail on the head: I would be much more concerned about what the sewer system was carrying than I would be about what it was constructed from. -ReAct "'13.2V...' Thirteen volts. It's thirteen volts? Jesus, I could practically be made of salt water and this wouldn't hurt me." "That says '13.2kV.'" "Ohhhh... Thirteen-thousand volts... I suppose that's a little different...."

It's most likely used as an aggregate and reinforcement inside the concrete, much like making mud bricks with grass in them or a composite boat with fiberglass strands within the epoxy shell.
