Feds show school bus support

At the annual conference of state pupil transportation directors, NHTSA Administrator David Strickland touts the safety and environmental benefits of the “humble yellow school bus,” as he calls it. NTSB Chairman Deborah Hersman credits state directors and others in the industry for their work to prevent school bus-train crashes.

Flammability issue
An alarming development discussed during the NASDPTS conference was that chemical companies are reportedly funding a nonprofit group that is lobbying state legislatures to adopt additional flammability standards for school buses.

Accordingly, NASDPTS unveiled a new position paper explaining that the standards being proposed aren’t suited for pupil transportation — and the industry’s own national specifications are actually more stringent.

The paper, developed by NASDPTS’ School Bus Manufacturers Technical Council, details the fire-related federal standards that apply to school buses, including FMVSS 302 — Flammability of Interior Materials.

The paper notes that flammability standards are also included in the industry’s National School Transportation Specifications and Procedures. A maximum burn rate is specified for floor covering, and passenger seats are to meet the criteria of the School Bus Seat Upholstery Fire Block Test.

One of the standards being proposed in the lobbying efforts is to require that school bus seats meet ASTM International Standard E1537, “Standard Test Method for Fire Testing of Upholstered Furniture.” But the School Bus Seat Upholstery Fire Block Test is more stringent and more reliable, the NASDPTS paper points out.

Another of the lobbyists’ proposed standards, the paper explains, is to require that each plastic component in school bus engine compartments meets a V-0 classification when tested in accordance with the Underwriters Laboratories (UL) Inc. Standard 94, “Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances Testing.” But the chemicals that would be used to meet that standard could be problematic.

“In addition to major concerns regarding durability and performance of plastic components made to meet the UL 94 V-0 classification, there are also concerns with the chemicals that could be required to treat the plastics,” the paper says. “Brominated Flame Retardant (BFR) chemicals are typically used to meet UL 94 V-0 classification, and it is unknown what effect these BFR chemicals could have on plastic components in the engine compartment environment.”

The position paper is available at www.nasdpts.org/Papers.

Compelling speakers
Other highlights of the conference included a keynote speech by former NBA All-Star Mark Eaton and a welcome address by Ohio state director Pete Japikse, in which he discussed changes in school transportation and the need to come up with new solutions to old problems.

Kim Koenigs, executive director of the Worth County (Iowa) Development Authority, gave a passionate presentation about her campaign to pass Kadyn’s Law, which is named after a local girl who was killed in May 2011 when a motorist illegally passed her school bus.

The 2012 NASDPTS conference is scheduled for Oct. 19-22 in Memphis, Tenn.
