Fire Safety Risk Remains High with Many Communications Cables Produced Offshore

August 24, 2012

An unacceptable public safety fire hazard still exists with some offshore-manufactured communications cable installed in buildings. Independent laboratory testing of cable samples reveals catastrophic results when exposed to fire.

The Communications Cable and Connectivity Association (CCCA) announced today it has new evidence that the North American market for communications cable products continues to be undermined by certain offshore-manufactured communications cable products which fail to meet industry fire safety requirements.

In July 2012, the CCCA again commissioned an independent test laboratory to analyze whether a sample set of offshore-manufactured cable samples met National Fire Protection Association (NFPA) minimum requirements for fire safety.

  • Test results showed that five of the six samples failed to meet the minimum NFPA code requirements for low flame spread and/or smoke generation for installation in commercial buildings, schools and multi-tenant residences.
  • Four of the five failing samples exhibited catastrophic results.
  • One cable specimen fire was so virulent that the test chamber had to be shut down in less than 3 minutes.
  • Extreme failures like these indicate an unacceptable public safety hazard still exists.

The CCCA conducted fire safety tests on samples of offshore cables in 2008 and 2009 with similar results. This latest round of testing was commissioned to determine if the problem has lessened since it was first brought to the public´s attention in 2008. The test results suggest that the problem is still very prevalent.

In addition to the fire safety tests, a separate laboratory tested all six samples to the electrical performance requirements for Category cables. Four of the five cables, which failed the fire safety requirements, also failed to meet minimum electrical performance required by industry standards for Category 5e and 6 cables, to which independent test certifications were also claimed.

“As in 2008 and 2009, these recently procured cables were made with inferior materials for this application and inadequate cable designs to cut production costs. Based on material analyses, samples predictably failed the minimum fire safety requirements,” says CCCA Executive Director, Frank Peri.

“The CCCA has taken the position that this serious problem will not go away until quality assurance procedures include testing of samples of finished cable procured directly from the marketplace,” Peri adds. “We commend UL for leading the industry and putting in place new quality assurance procedures in response to this problem. It is significant that none of the failing samples were certified under UL´s fire safety listing program. This also means that unscrupulous manufacturers may be moving to other testing agencies with more lenient quality programs, or using unauthorized marks from these agencies. This is disturbing and our concern cannot be understated because these potentially hazardous cables are being installed in buildings today. The potential liabilities we have addressed and risk to public safety in the event of fire are unacceptable.”

In advance of the fire safety tests, the CCCA also commissioned a test laboratory to analyze the materials contained in each of the six cable samples for flame and smoke retardant characteristics. These analyses proved to be reliable predictors of the fire safety test results obtained. Peri comments, “As we have demonstrated twice now, material testing is a viable means of predicting fire safety performance from samples obtained in the marketplace and can be accomplished with samples as short as 5 feet in length.”

Cables selected for the tests were all procured from the inventory of six separate distributors in North America in April 2012 and were comprised of six different brands of plenum rated Category 5e and Category 6 cables. The brands chosen would largely be considered “unknown” by most buyers in North America. These types of cables are commonly installed behind walls and in ceiling cavities in commercial or institutional buildings, and are connected to wall outlets that have phone or Ethernet ports. The invisible placement of these cables makes their flame and smoke characteristics particularly critical because combustion would not be evident to inhabitants until after the fire had significantly progressed.

The CCCA continues to believe that buying quality, name-brand cables is the best practice to assure compliance to fire safety requirements.
