The Class 9 label is used to alert the airline staff that an Acceptance Check List is needed for acceptance and the shipment must be listed on the NOTOC. Due to this purpose, alike the other labels Mar ings, these two labels must be readily visible and legible and not obscured by other labels or Mar ings.
The label location is as spelled out in DGR 22.214.171.124 and 126.96.36.199. The packagings must be of such size that there is adequate space to affix all required Mar ings and labels as stated in DGR 188.8.131.52.4.
The revision effective 2013, is to alert the airline staff that Section IB requires an Acceptance Check List and listing on the NOTOC.
To accomplish this purpose, there is a definite cause to have these two labels to be affixed adjacent to each other. There is a distinct purpose in having these two labels shown alongside each other.
