  • Background
  • Summary of the new rules
  • What to expect when FMCSA and the States begin to
    enforce the rules
  • What you can do to help the FMCSA continue to
    improve the rules

3
Background Research
  • U.S. and Canada established a cargo securement
    research program in 1993.
  • State and Provincial agencies, industry experts
    participated in identifying research needs.
  • Research and testing of securement systems was
    conducted between 1994 and 1998.

4
Background - Research
  • Participants in the research program agreed to
    develop model regulations that would be based
    on the research results.
  • Each jurisdiction in North America would then be
    asked to adopt the model regulations uniform
    rules throughout North America.

5
Background Drafting the Model Rules
  • A Drafting Group was formed in 1996 to begin
    developing model rules.
  • A Harmonization Committee was formed so that all
    interested parties could comment on the draft
    standards.
  • Public meetings were held in the U.S. and Canada
    from 1996 through 1999.

6
Background Publication of Model Rules
  • Model Regulations were published in May 1999.
    Additional information is available at
    http//www.ab.org/ccmta/ccmta.html
  • Research reports and other information reviewed
    by FMCSA may be viewed at http//dms.dot.gov
    Docket 2289.

7
Summary of FMCSAs Rules
  • Based on the North American Cargo Securement
    Model Regulations.
  • Reflects the results of the multi-year
    comprehensive research program.
  • Responsive to comments to the December 2000 NPRM.

8
Summary (continued)
  • We considered the industry's best practices
    and recommendations presented during a series of
    public meetings involving U.S. and Canadian
    industry experts, Federal, State and Provincial
    enforcement officials, and other interested
    parties.

9
Performance requirements 393.100
  • Cargo securement system must prevent the cargo
    from leaking, spilling, blowing or falling from
    the motor vehicle.
  • Cargo must be contained or secured to prevent
    shifting upon or within the vehicle to such an
    extent that the vehicles stability or
    maneuverability is adversely affected.

10
Performance requirements 393.102
  • Securement devices and systems must be capable
    of withstanding the following three forces
  • (1) 0.8 g deceleration, forward
  • (2) 0.5 g acceleration, rearward
  • (3) 0.5 g acceleration, lateral.

11
Standards for securement devices 393.104
  • Vehicle structures, systems, parts, and
    components used to secure cargo must be in proper
    working order.
  • Chains, wire rope, steel strapping, synthetic
    webbing, and cordage used to secure articles of
    cargo to, or in, commercial motor vehicles must
    conform to manufacturing standards.

12
393.104 (continued)
  • Chain NACM, Welded Steel Chain
  • Specifications.
  • Steel strapping ASTM D3953-97.
  • Webbing Web Sling Tiedown
  • Association, WSTDA-T1
  • Wire Rope Wire Rope Technical Board Users
    Manual

13
393.104 (continued)
  • Tiedowns must be attached in a manner that
    prevent them from becoming loose, unfastening, or
    opening while the vehicle is moving.
  • Tiedowns and components of securement system must
    be located inboard of rub rails when practicable.

14
393.104 (continued)
  • Edge protection must be used whenever a tiedown
    would be subject to abrasion or cutting at the
    point where it touches an article of cargo.
  • Edge protection must resist abrasion, cutting and
    crushing.

15
393.104 (continued)
  • Labeling or marking of tiedowns and anchor points
    is NOT required.
  • Use of friction mats is encouraged but NOT
    required there are NO marking requirements for
    mats.
  • Motor carriers are NOT required to purchase any
    new equipment.

16
General versus commodity specific 393.106
  • General rules concerning securement, working load
    limits, blocking and bracing are applicable to
    all commodities being transported.
  • Commodity-specific rules take precedence over the
    general rules when additional requirements are
    given for that commodity.

17
393.106 (continued)
  • Cargo must be firmly immobilized or secured on or
    within a vehicle by structures of adequate
    strength, dunnage/dunnage bags, shoring bars,
    tiedowns or a combination of these.
  • Items that are likely to roll must be restrained
    by chocks, wedges, a cradle or other equivalent
    means.

18
Example - dunnage bag
19
Example - protection against rolling
20
393.106 (continued) Working Load Limit (WLL)
formula
  • WLL 1/2 x (weight of the cargo).
  • Total WLL is the sum of
  • (1) 1/2 of the WLL of each connector or
    attachment mechanism used to secure the cargo to
    the vehicle and
  • (2) 1/2 of the WLL for each end section of a
    tiedown that is attached to an anchor point.

21
How many tiedowns? 393.110
  • The rules in this section are in addition to
    Section 393.106 concerning WLL.
  • When an article of cargo is not blocked or
    positioned to prevent movement in the forward
    direction, the number of tiedowns needed depends
    on the length and weight of the articles.

22
393.110 (tiedowns continued)
  • 1 tiedown for articles 5 ft or less in length,
    and 1,100 lbs or less in weight
  • 2 tiedowns if the article is -
  • 1) 5 ft or less in length and more than 1,100
    lbs in weight or
  • 2) gt 5 ft but less than 10 ft, regardless of
    weight.

23
Example of 110(b)(1)
24
393.110 (tiedowns continued)
  • 2 tiedowns for articles longer than
  • 10 ft, and one additional tiedown for every 10
    ft of length, or fraction thereof, beyond the
    first 10 ft.
  • If an article is blocked to prevent movement in
    the forward direction, 1 tiedown for every 10
    ft, or fraction thereof.

25
Example of 110(b)(3)
26
Example of 110(b)(3) - Articles blocked to
prevent forward movement 1tiedown for each 10 ft
of length, or fraction thereof.
27
393.110(d) Special Purpose Vehicles
  • Generally, basic rules do not apply to a
    vehicle transporting one or more articles of
    cargo such as, but not limited to, machinery or
    fabricated structural items (e.g., steel or
    concrete beams, crane booms, girders, and
    trusses, etc.) which, because of their design,
    size, shape, or weight, must be fastened by
    special methods.

28
Example of a special-purpose vehicle
29
393.114 Front-End Structures
  • The rules are applicable only to front-end
    structures or headerboards used as part of the
    securement system.
  • The performance standard applies only when the
    cargo is in contact with the front end structure
    of the vehicle.

30
Example of front end structure
31
Commodity-Specific Rules
  • 393.116 Logs
  • 393.118 Dressed Lumber Similar
  • Building Products
  • 393.120 Metal Coils
  • 393.122 Paper Rolls
  • 393.124 Concrete Pipe
  • 393.126 Intermodal Containers

32
Commodities (Continued)
  • 393.128 Cars, Light Trucks, Vans
  • 393.130 Heavy Vehicles, Equipment, and
    Machinery
  • 393.132 Flattened and Crushed Cars
  • 393.134 Roll-on/Roll-off Containers
  • 393.136 Large Boulders

33
What should you expect when we enforce the new
rules?
  • Same inspection procedure less confusion about
    determining compliance whether the system
    complies with the rules.
  • Same process for placing vehicles out of service
    for violations CVSA has revised the OOS
    Criteria to match the new rules.

34
What can you do to help the FMCSA continue to
improve the rules?
  • Review the final rule and let us know if you
    believe there are things in the new rules that
    just dont work in the real world.
  • Let us know if there are portions of the rule
    that are so confusing, you cant understand it.
