Safety in the spotlight post cruise disaster

In the wake of the Costa Concordia cruise liner disaster off the Italian coast, cruise safety protocol is likely changing at many cruise lines.

"We have something called Safety of Life at Sea, SOLAS, which we've all been focused on the muster drill, the lifeboat drill. (Cruise lines) won't wait for the rules to change," CBS' travel editor Peter Greenberg said. "The cruise lines will change that on their own, (they'll say) 'From now on, we'll have that lifeboat drill before the ships leave their first port.'"

However, other problems are more systemic. While many cruise lines tout that they have a crew that speaks many languages, Greenberg said this is a problem during a disaster.

"I laugh when (cruise lines) say, 'We boast that our crew comes from 37 different countries.' Excuse me? In the event of an emergency, they can't talk to the passengers or each other. You need a standardization of language and then comes the cross-training in terms of the hours that they're working," he said.

"The real problem is, the cross-training of the crew, the actually training regimen of the crew, and you won't wait for a rule to come in because it takes all the countries to get into one room at one time to do it. Each cruise line has to do that ahead of time." Greenberg said.
