Dear Mr. Pace:
This letter is in response to your March 26, 2019, email requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CPR Parts 171-180) applicable to the package securement
requirements for highway transportation. Specifically, you include three photographs of
packages containing hazardous material shrink-wrapped onto wooden pallets. The pallets are
loaded side-by-side in a motor vehicle, with gaps of at least several inches between the pallets
and between the pallets and the walls of the trailer. The pallets are not secured to the vehicle
using straps, tie-down, load locks or other means, although you indicate that a means of
securement will be used to prevent the pallets from shifting backwards toward the doors of the
trailer. You ask whether the arrangement depicted in the photographs meets the requirements of
§ 177.834(a).
Based on the photographs and information provided in your email, we cannot definitively
determine whether the load is secure. Section 177.834(a) requires any hazardous material
package that is not permanently attached to a motor vehicle to be secured against shifting,
including relative motion between packages, within the vehicle on which it is being transported
under conditions normally incident to transportation. Conditions normally incident to
transportation include vehicle starting, stopping, cornering, accident avoidance, and varied road
conditions. Thus, the securement of hazmat packages requires that such packages do not shift
when experiencing these conditions.
As shown in the photographs, the voids between the pallets and between the pallets and the sides
of the trailer could allow the pallets to shift, and there is no securement mechanism in place to
prevent the pallets from shifting in this way. Specific methods for securing packages in a motor

vehicle are not provided in the HMR. However, various methods, such as tie-downs, using
dunnage or other cargo, shoring bars, jack bars, or toe-boards would be acceptable to secure the
pallets as long as they prevent shifting within the trailer.
I hope this information is helpful. Please contact us if we can be of further assistance.

Subject: RE : Interpretation Request
Good afternoon.
I received a call earlier from one of your staff (Brianna) in reference to the attached lnterp. request. Brianna directed me
to an existing lnterp. letter 11-0198 (attached) as guidance to my request submitted yesterday, which I appreciate.
The purpose of this request was to validate to a customer (shipper), using pies of their cargo loading method, that
177.834 (a) requires any hazmat packages not permanently attached to a motor vehicle be secured to prevent against
shifting into void areas during transportation. I had previously addressed this with the customer and provided 3 separate
interp. letters (including attached 16-0088). We as a carrier do not need the unnecessary DOT roadside securement
violations and the 36 CSA points associated with hazmat securement violations nor do we wish to lose their business.
We'd rather educate them on proper securement of their cargo to meet 177.834(a) .
If it's possible, could I get a response to my request (using the customer's pictures), if it's your office's opinion that the
pallets in provided pictures, do not meet the requirements in 177.834(a) as the pallets can clearly shift into void areas
during transport. I thought a response using pies of their loading methods/cargo would be better suited to get the point
across.
Your help is greatly appreciated. If I'm asking too much of you, I do understand.

Dear Mr. Pace:
This responds to your August 17, 2011 request for clarification of§ 177.834(a) in the Hazardous
Materials Regulations (HMR; 49 CFR Parts 171-180). You provide a photograph showing one
row of pallets loaded side-by-side with four drums per pallet leaving a void space between
pallets and a second row of pallets containing five gallon pails. The five gallon pails are shrink
wrapped together and to the pallet. Two straps secure the load. You indicate that the HMR are
silent in regards to securement of a packaging to a motor vehicle. Based on the photograph
provided in your letter, you ask if this shipment would be in violation of the securement
requirements in§ l 77.834(a).
You are correct in your understanding that specific methods of securement are not provided in
§ l 77.834(a). Section 177.834(a) requires any hazardous material package that is not
permanently attached to a motor vehicle to be secured against shifting, including relative motion
between packages, within the vehicle on which it is being transported under conditions normally
incident to transportation. Further, general requirements addressing protection of shifting cargo
are found in the Federal Motor Carrier Safety Administration Regulations (49 CFR Parts 300-
399), specifically under § § 393 .100 to 393 .106. These requirements allow varied methods of
securement, such as blocking with other freight, banding, or use of tie-downs or load-locks.
Based on the photograph and information provided in your letter, we cannot definitively
determine whether the load is secure. However, securing the load by shrink wrapping the
packages to a pallet and straping the pallets in place is one method for securing the load in
accordance with§ 177.834(a).
I hope this answers your inquiry. If you need additional assistance, please contact this office at

Mr. Betts,
Please except this letter as my request for an interpretation specific to 177.834(a). I understand the regulations are
silent on what method of securement must be used, provided the requirements are met. I also understand various
methods of securement that would meet the requirement as defined in FMCSR parts 393.100 to 393.106 and
177.834(a).
A customer questions my understanding of securement as it relates to the securement of loose drums (55 gallon) on
pallets. The enclosed picture shows pallets are loaded side by side with 4 drums per pallet leaving a void space of l+
feet between pallets and the last 2 side by side pallets contain 5 gallon pails which are shrink wrapped together and
to the skid themselves and 2 straps on rear of load.
My understanding is that loose drums "sitting on pallets with no means used to prevent shifting and/or falling would
be contrary to the intent of 177 .834(a). Based on the provided picture, would this shipment be in violation of not
meeting the securement requirements?
Your assistance is greatly appreciated,

Dear Sir,
I'm seeking clarification if the cargo securement In attached pictures would be compliant with requirements
in 177.834(a) as written.
As shown in pictures, pallets of paints are shrink wrapped and loaded in a side by side configuration from
front of trailer to the rear. As evident from pictures, there are sizable gaps/void areas between pallets with
no means of securement to prevent the individual pallets from shifting, including relative motion between
packages.
It's the opinion of the shipper that these shipments only need securement on the rear of cargo to prevent It
from shifting backwards towards the doors with no means of securement to prevent pallets from shifting Into
void areas between pallets within the trailer.
It's my belief that the unsecured pallets within the trailer could shift around during the course of
transportation including starting, stopping, cornering, accident avoidance varied rough road conditions and
could/would be potential securement violations at roadside inspections.
Your assistance in providing clarification would be greatly appreciated.

Mr. Wes Pace

Reference No. 16-0088
Dear Mr. Pace:
This letter is in response to your May 11 , 2016 email, letter, and two photographs requesting
clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180)
applicable to loading and securing pallets of hazardous materials. Specifically, you ask if the
loading and securement packing method you describe complies with the intent of
§ 177.834(a).
You state your transpo11ation scenario, as further demonstrated in the attached photographs,
is as follows:
• Four drums are loaded on one pallet,
• Drums on the pallet are shrink-wrapped to the pallets,
• Heavy cardboard is placed on top of each set of four drums banded to a pallet,
• An even nmnber of these pallets arc loaded side-by-side in a freight trailer,
• Pallets are loaded in the freight container with approximately 3--4 inches of void area
between them,
• Pallets closest to the freight container door are secured with two straps,
• This loading and securement method makes it difficult, if not impossible, to nail a
2 x 4 inch blocking to the freight container floor in the void area, and
• This bl. ocking method makes it highly unlikely for these drums to shift or fall to the
extent that they become damaged.
It is the opinion of this Office that the transportation scenario you provided does not comply
with the intent of§ 177.834(a). The three to four inches of space between pallets in the
freight container loading and securement method you describe provides a foot or more of
space in which the end pallets can shift during transportation. Section 177.834(a) requires
any hazardous material (hazmat) package that is not permanently attached to a motor vehicle
to be secured against shifting, including relative motion between packages, within the vehicle
on which it is being transported under conditions normally incident to transportation ( e.g.,
vehicle starting, stopping, and cornering; accident avoidance; and varied road conditions).

<<<PAGE 13>>>

Thus, the securement of hazmat packages requires that such packages do not shift when
experiencing these conditions. Part 393, Subpart I of the Federal Motor Carrier Safety
Regulations (49 CFR Parts 300-399) contains general requirements that address protection
against shifting and falling cargo.
I hope this information is helpful. Please contact us if we be of further assistance.
Sincerely,

Subject: Interpretation Request
Dear Sir:
I'm requesting an interpretation and clear understanding of 177.834(a) and when the intent of
the rule has been met with a specific loading method and the securement of pallets in my
scenario. I understand regulation is silent on what method must be used and also that intent of
securement is to prevent shifting, including relative motion between packages within the
transport vehicle under conditions normally incident to transportation.
My scenario, as shown in attached pictures is:
• 4 drums loaded per pallet. Drums are shrink wrapped to the pallets and also have heavy
cardboard placed on top of each set of 4 drums which is then banded to the pallets
• An even number of pallets are then loaded side by side in the trailer.
• Once pallets are loaded, there is roughly 3-4 inches of void area located in-between the
pallets
• The pallets are then secured with 2 straps on the rear of the load
Based on this loading and securement method, it's difficult and almost impossible to have 2 X 4
blocking nailed to the floor in the small void area. Under conditions normally incident to
transportation (vehicle starting stopping, cornering, accident avoidance and varied road
conditions) the possibility of these drums shifting or falling to the extent that the drums could be
damaged are highly unlikely.
One state interprets 177.834(a) as meaning any void are must be filled or pallets blocked to
prevent shifting of any amount and that this referenced loading and securement method is in
violation of the rule.
Based on the scenario provided, would the true intent of 177.834(a) be met?
