Furniture Safety and the South Carolina Disaster

American furniture products should be in the spotlight again following the South Carolina fire that killed nine of Charleston’s best.

In 1993 American fire marshals were already campaigning to improve furniture fire safety. However, by 2000, little progress had been made and a law firm in South Carolina called Foster and Foster wrote an advisory called “Flammable Upholstered Furniture: Is there a deadly time bomb in your couch?”

Robert P. Foster has brought legal action against a maker of upholstered furniture causing injury and death under product liability theories of strict liability, negligence, and warranty. “Its excessive flammability makes it an unreasonably dangerous product well beyond the reasonable expectations of the ordinary consumer.”

The primary flammability culprit is polyurethane foam, the seating cushioning core that shares some of the same combustion properties as kerosene and gasoline. It is a petroleum based product sometimes called solid gasoline

Fast forward to this morning when people are discussing similar conditions under which a “fire tornado” whipped through a Carolina warehouse stuffed to the brim with furniture for a giant sale.

Bloomburg’s report shows that while presence of a sprinkler system could be significant factor, the quantity of “solid gasoline” is also important:

The one-story building had no sprinklers, said Mike Parrotta, president of the International Association of Fire Fighters-South Carolina.

“It appeared they were having a closeout sale, so it’s likely they were overstocked and the fire load was greater than normal,” Parrotta said.

Firefighters are professionals, not just ordinary consumers, but would they have acted differently if they had been looking at a warehouse of gasoline in front of them rather than furniture?

Furniture does not have to be made with solid gasoline, obviously. When I used to work on furniture repair I always saw cotton and burlap padding as easier to work with and more comfortable. I found nothing more unpleasant than working on toxic foam-based products. The furniture industry is driven by a very different set of values, however, as flammability and toxicity of furniture is not regulated in America and remains a significant source of risk:

For three decades, most upholstered furniture and mattresses sold in America have contained flexible polyurethane foam, the plastic material that was used as soundproofing around The Station nightclub stage. It’s found in couches, love seats, chairs, recliners, mattresses, mattress pads and mattress toppers, pillows, carpet cushioning and many other places.

More than 2 billion pounds of foam enters the U.S. market every year.

Foam is comfortable and comparatively cheap — and once ignited, it can be lethal. Mattress, bedding and upholstered furniture fires killed almost 30,000 Americans from 1980 to 1998, the latest year for which National Fire Protection Association (NFPA) data are available. Another 95,655 people were injured.

From 1980 to 1998, mattress and bedding fires killed 12,712 Americans, according to the NFPA — 10 times more than all those killed by tornadoes and hurricanes combined.

Almost 4,000 people killed a year, and that’s old news. By 2002 the number was up to almost 5,000 people killed a year, according to a FAQ by firemarshals.org:

If furniture manufacturers made some small, inexpensive changes to the materials they use, they could save hundreds of lives and prevent thousands of serious injuries every year.

They also point out that empirical evidence of success is easy to find:

California is the only state with fire safety regulations for upholstered furniture sold for use in homes. According to the California Bureau of Home Furnishings there was a 25% drop in deaths involving upholstered furniture after these standards were put into place in the 1970s.

The UK also has regulations for furniture. In addition “upholstery in airplanes, hotels, nursing homes, hospitals and even prisons is required to be fire resistant.” But consumer products outside California are left unregulated. The firemarshals.org FAQ does a nice job putting it in perspective:

It’s a funny thing about competition. The auto industry said airbags were unaffordable. The mattress industry said that fire safety standards would add hundreds of dollars to the price of each mattress. Consumers are still buying lots of cars and mattresses.

Perhaps the unfortunate death of the firefighters will bring the federal government to its senses. Nine brave men lost their lives trying to save others. There is no country to invade, no foreigners to blame, but here is a clear case where America’s national security (one less vulnerability in every home) could be improved by a simple stroke of the pen.

Motorcycle Safety and the Derbi Mulhacen

I just read an amazing recount of a motorcycle accident by Sylvia Stuurman and her subsequent path to recovery. The reconstruction of the accident and thoughts about managing risk are interesting.

She also has some great insights on motorcycle touring and engineering. She makes a good case for the Derbi Mulhacen. Would she have migrated from a giant “adventure” 1200 BMW to this smaller, more nimble, bike if not for the accident?

mulhacen For what it is worth, the Mulhacen is said to be the largest bike ever made in Spain, but it’s incredibly small compared to the latest American and German designs.

Does anyone really think 1600cc is a safe or reasonable platform for two wheels? Even 1200 seems out of proportion to me. I couldn’t help but notice the Mulhacen was designed by a German engineer, Klaus Nennewitz, who also helped Aprilia make the Tuono, and the engine is a Yamaha design. Derbi is a subsidiary of Piaggio, the famous scooter company. This new take on the 1970s scrambler concept is probably far too sensible (it’s a long long way from the current fad of chrome-covered American garage queens and show boats) to be shipped to the US market for some time.

The only thing I’d change is to make it a diesel-hybrid instead of yet another gasoline bike. But I guess that would be changing a lot, eh?

Entity Resolution

Spock has a problem they want to pay someone $50K to solve for them:

A common problem that we face is that there are many people with the same name. Given that, how do we distinguish a document about Michael Jackson the singer from Michael Jackson the football player?

That is worth far more than $50K, it seems to me, since it directly impacts all our privacy, not to mention the future of criminal investigations.

The Chinese government is already working on a solution, from a slightly different perspective:

Police in China, where most of the 1.3 billion people share just 100 surnames, are considering rules which would combine both parents’ family names to prevent so much duplication, state media said yesterday.

[…]

“By adopting both parents’ names, 1.28 million new surnames will be added, which will greatly solve the problem of name duplication,” Xinhua news agency said, citing the regulations.

This is just the beginning of the problem. Future generations may more commonly treat names as an evolutionary thing, rather than static. So the question will become how to tie together a history/path of names throughout someone’s life.

On a related note, mandarintools.com has a Chinese name generator. It would be funny if it only had ten names to choose from, based on the latest reports coming from China, but unfortunately it actually tries to create uniqueness.

Every time I run the program I get a completely different answer. Or should I say a differently resolved entity?

Bush may intentionally violate data-retention laws

It’s not just about explaining how/when the President does not have to honor seatbelt laws. Now it’s about data retention violations too:

“Given the heavy reliance by White House officials on RNC e-mail accounts, the high rank of the White House officials involved, and the large quantity of missing e-mails,” the report said, “the potential violation of the Presidential Records Act may be extensive.”

Republicans said there is no evidence that the law was violated or that the missing e-mails were of a government rather than political nature.

The records act requires presidents to assure that “the activities, deliberations, decisions, and policies that reflect the performance” of their duties are “adequately documented … and maintained,” the report said.

Of course there is no evidence. That was destroyed too, along with the definition of government.
