Moscow subway attack: Five ways to make mass transit safer

Washington has the program in a dozen stations and Boston has also implemented a permanent program. Chicago, San Francisco, and other cities are interested.

“We need the kinds of things that help integrate the data from information that is coming in from sensors and cameras,” says Charlie Fisher, vice president for the Mid-Atlantic Region of Witt Associates, a public safety and crisis management consulting firm. “That information has to be processed for security people in order to improve their situational awareness.”

But there’s a money factor for most transit systems. Federal funding does not cover the cost, nor do subway operators' general funds. Mr. Fisher says many municipalities are pushing DHS for more federal grants to support such mass-transit detection systems.

3. Germ Warfare

The Houston Metro system has successfully tested the Breathe Safe System, which uses Ultraviolet Germicidal Irradiation to kill up to 99 percent of certain types of bacteria. The primarily goal is hygienic: preventing the spread of viruses such H1N1, bacteria, or mold.

But the technology is also evolving to prevent against a biological attack on a mass transit system. Many office buildings already use this technology to guard against an airborne threat. The next step would be to add the such systems to subways in major metropolitan areas.

4. Blankets

New York City recently received some new tools in its battle against a possible attack: shields, vests, and blankets made from Demron, a state-of-the-art fabric blend that blocks chemical, biological, and nuclear agents.

The shields and vests would be used by first responders. Blankets would be thrown over radiation victims to keep them from irradiating others. Another blanket – the “Hi-Energy Nuclear Suppression Blanket” – is designed to be placed over a dirty bomb about to go off. It traps chemical, biological, and nuclear agents and reduces by more than half the distance they can spread.

One goal is to make these blankets as common on subways as oxygen masks are on planes.

5. Emergency preparedness

The old tried-and-true security drill is still the best, security experts say.

Transit systems regardless of size and capacity should have a plan for all possible disasters. Conducting exercises regularly is also crucial to avoiding a disaster or preventing mass causalities.

Earlier this week, the Washington Metropolitan Area Transit Authority held two emergency response exercises involving simulated explosions on Metrorail and Metrobus “to test and practice the multi-jurisdictional coordination and response needed to mitigate such incidents,” according to WMATA Metrorail’s website.
