Reference No. 12-0182
Dear Mr. Brady:
This is in response to your August 15, 2012 e-mail requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to placarding requirements.
Specifically, you ask what is the correct way to display placards on a motor vehicle under
§ 172.516(a).
You enclosed photographs that show a pair of adhesive-backed CORROSIVE (Class 8)
placards displayed vertically on three sides and horizontally on the hood of a Chevrolet
C1500 pickup truck. One placard has the word "CORROSIVE" printed in large letters
across its center but does not have the number "8" in the bottom corner. The second placard
has the UN number "1791" printed in large numbers across its center and the number "8" in
the bottom corner. Your photographs also show the placards on the hood are placed with
their bottom corners approximately three inches above the truck's front grill on either side of
the hood but just inside the area above the headlights. You state you placed the placards on
the hood in this manner because placard holders were difficult to affix to the vehicle and
simultaneously became a safety hazard and placard violation when they came off while
travelling on a highway. You ask if the manner in which these placards are placed on the
hood satisfies the requirement in§ 172.516(a) of the HMR.
The answer is no. Section§ 172.516(a) requires a placard to be clearly visible from the
direction it faces, except from the direction of another transport vehicle to which it is
coupled (see§ 172.516(a)). The placards on the truck hood in the photographs you provided
do not satisfy this requirement because their placement causes their designs to be
partially obscured when viewed a few feet in front of, or to the side of, the vehicle. Further,
the placard with the word "CORROSIVE" printed in its center does not comply with the
image of the CORROSIVE placard prescribed in § 172.558 because it is missing the number
"8" in its bottom corner.
I hope this satisfies your request.
Sincerely,
c--7rY'k/V~ ---.

Subject: Placard Intrepetation
This email is being sent to request your opinion on intrepretation of Placarding under 172.516(a).
I have a small Swimming Pool Service company in Lewisville for over 30 years now and we have been using
Sodium Hyprchlorite as our Sanitizer in-lieu-of conventional Dry Chlorine since 1999. In order for us to meet
our needs I have utilized a Tank in our trucks that holds a max of 192 gallons of Bleach starting in 1999. There
is not any disagreement on whether the DOT Placarding & Licencing is applicable as we are in full compliance
with all laws; requirements for Sodium Hypochlorite is 1000# which is equal to 100 gallons@ 10#/gallon. The
only issue is whether the placement of the Placard meets the requirements of 172.516(a). One of our trucks was
recently stopped by our local Lewisville Commercial Enforcement Officer & was cited for a violation of
172.516(a).
I spoke with a representative in your office & I was told to send this request for an official response on the
matter. I understand that a written response might take some time but that a "preliminary response" could be
sent relatively quickly. I am currently in the process of refuting this Violation & am scheduled to appear in our
local Muncipal Court. I have asked 2 other local cities & a local Fire Department for their opinion & they felt
the location was "plainly visable". It is best to address this item with you so that we can put this item to rest. I
am attaching photos ofthe vehicle as I am requesting an intrepretaion if my current placement of the Placards
on the Hood of the vehicle is acceptable under the current statute. I had used many versions of the standard
Placards & Holders over the years but became very concerned about the Safety Issue with the Placards/Holders
flying offthe truck while it was on the Highway(s). It is very difficult(ifnot impossible) to affix such a Placard
on the front of a standard vehicle that does not create more problems than it solves. There have been 3-4
instances of the Placards coming off so I made a decision to place the Placards on the Hood of the truck;
therefore eliminating 100% the risk of accidentally losing any more Placards. I feel that my placement of the
Placards does not conflict with the Statute as they are clearly visable from the front & are not surrounded by any
other things that would detract from the placard. These Placards are plainly visable to any 1st Responder in the
event of an accident & that is what they are really for. I am attaching photos of the truck which is a standard
Chevrolet C1500 1/2 ton Pickup & a 6.5" standard pickup bed. All other 3 sides of the truck are not in question
and the Tank also is placarded & marked with the appropriate information. Please be advised that in the second

picture (truck in the background) that one of our Employees went ahead & put more 1791 Placards on his
Bumper in order to try & cover all the bases.
I look forward to hearing from you. I would appreciate an "informal opinion email" which would be sufficient
in advance of a written response. Thank you for your time & interest in this matter. I can be reached @ 972-
221-1213 or 972-880-6404 if I can clarify any items you need or if there are additional questions. A written
response can be sent to: ChemPura Pools, Ltd
