Cargo securement rule changes may land this year
An alliance of DOT enforcement agencies is seeking significant changes to federal cargo securement rules.
The Commercial Vehicle Safety Alliance (CVSA) has asked the FMCSA to make several revisions that would alter the way tiedowns and friction mats are used. The FMCSA may include at least some of the requested changes this year as it works on updating the cargo securement rules in 49 CFR Part 393, Subpart I.
Unenforceable standards
Calling them “unenforceable,” the CVSA wants the agency to amend the performance standards in 393.102(a), which have long caused confusion for both motor carriers and enforcement officials alike. That section of the rules sets standards for a tiedown’s breaking strength and working load limit (WLL) in relation to the g-forces that may be applied. However, those standards have no practical application for everyday tiedown usage and are rarely cited.
Direct tiedowns
The CVSA also wants the FMCSA to remove the need for drivers to, in effect, use twice as many tiedowns when they’re attached directly to the cargo or only pulling the cargo in one direction rather than crossing over the cargo and pulling down.
When calculating how many tiedowns they will need, drivers currently may count only half of a tiedown’s WLL when it’s attached in a “direct” manner.
By contrast, Canada allows drivers to use the full WLL for direct tiedowns, which means drivers must follow “vastly different cargo securement requirements when moving between countries,” the CVSA noted.
Friction mats
Finally, the CVSA wants a better definition of “friction mat,” currently defined as any “device” placed under or between cargo to increase friction. No matter what material is used as a friction mat, §393.108(g) says it will be assumed to “provide resistance to horizontal movement equal to 50 percent of the weight placed on [it],” unless marked otherwise.
The “vague” definition has led drivers and shippers to use “a wide range of materials … many of which likely do not account for securement of 50% of the weight placed on the mat,” the CVSA wrote.
The group wants:
- The 50-percent allowance to be removed,
- Friction-mat manufacturers to mark their products in a way that allows drivers and officers to tell how much friction the mats provide (this is something that Canada currently requires), and
- The FMCSA to specify how friction mats should be used.
The only rules that refer specifically to the use of friction mats are those for securing paper rolls (393.122) and metal coils (393.120). Friction mats are optional in most cases, however.
We should know soon whether the CVSA’s requested changes will find their way into the regulations.
How many tiedowns do you need?
Determining how many tiedowns are required for a given load depends on many factors. Among them:
- The combined (aggregate) WLL of the tiedowns, which must be at least half the weight of the items being secured and depends on how the tiedowns are attached (see 393.106(d));
- Whether the tiedowns are marked with a WLL (see 393.108);
- The cargo’s weight, length, and placement (see 393.110); and
- Whether any commodity-specific rules apply (see 393.116 – 393.136).
Key to remember: The CVSA is asking for important changes to the federal cargo securement rules. If adopted, the changes would affect how many drivers secure their cargo.
