The open burning season has begun in the tri-town (and in Massachusetts overall). Thanks to November windstorms and January blizzards, there's a lot of surplus firewood around. As burning season doesn't end until May 1, according to the state, there's plenty of time to get rid of those twigs.

Don't just go start up a fire, though; permits must be obtained from a local fire station prior to striking up the matches or lighter. Those with a permit are reminded that having a burning permit does not release the holder of the permit from any fire damages or liability that may occur.

April, near the end of the burning season, is the most dangerous time to burn, according to the state. The previous year's dead grass and leaves are dangerous, and winds tend to be stronger and more predictable during that month. Those looking to burn are asked to burn earlier in the season, so that winter weather and wetness can hinder the spread of fire; due to the unpredictability of April weather, it is also likely that the state will close more days to burning than earlier in the season.

Fire departments take calls for burning permits during the morning. The state determines whether burning will be allowed in the state on a day-by-day basis.

A fire cannot be started prior to 10 a.m., and must be extinguished by 4 p.m. All open burning must be at least 75 feet from any structure, and fires should be attended at all times.

Bonfires are not permitted! Burning of large piles is prohibited. Only small brush piles are acceptable for burning, to help keep possible fire spreading contained. Those burning must have water, shovels or rakes available at all times to control the fire. Only brush and forest debris, such as sticks and small logs, can be burned. That means no grass hay, leaves stumps or burning materials.

Planning to burn on a windy day? Think again. If wind gusts kick up and exceed 10 mph, burning permits immediately become invalid and the fire must be extinguished.

Local fire departments retain the right to revoke a burning permit at any time.
