FAA warns flight attendants about exploding coffee filters
Washington (
CNN) -- When a flight attendant serves up a cup of coffee, fliers are unlikely aware of just how much risk the crew took to deliver them that cup of joe.
According to a safety alert published on the Federal Aviation Administration's website, the prepackaged coffee filters many airlines use are susceptible to pressure buildup and can explode when an unsuspecting attendant lifts the coffee pot to pour a cup.
Coffee makers on airplanes, similar to home drip-style coffee makers, have the filter and coffee grounds above the coffee pot. Many airlines use prepackaged coffee sealed within the coffee filter for convenience and ease of cleanup.
When the filters are incorrectly placed in the coffee maker the water can become blocked from dripping into the coffee pot below and pressure builds up within the container holding the filter and coffee grounds. When an unsuspecting flight attendant removes the coffee pot, the clogged compartment above suddenly has much more room to expand and the filter can burst, with its hot contents and hot water possibly injuring passengers and crew. ................(more)
