Dear Sir:
the segregation table. We question the meaning of the wording "may not be stowed together with that
We would like a written interpretation to the regulations cited as 49CFR 175.78(c)(4) regarding "note 2" of
class". Does "stowed together" mean "may not be placed next to each other or in a position that would
allow a dangerous interaction in the event of leakage" as spelled out in 175.78(a), or is 175.78(c)(4) meant
to be more restrictive?
Your attention to this question would be appreciated.
Sincerely,
Spaine
