Every time there's a hurricane, workers die, usually from electrocutions or falling tree branches. The recovery of the Gulf Coast could take months or years, which means that organic material will rot, creating hdyrogen sulfide, methane and oxygen depletion, and in enclosed areas, confined space hazards.
Just because we're dealing with a disaster doesn't mean that OSHA standards, safe working procedures and protective equipment should be overlooked.
OSHA has an alert and a number of fact sheets containing information on avoiding hazards and safely cleaning up after a hurricane.
Check it out if you're working on recovery or know anyone who is.
