OKLAHOMA CITY - All 77 Oklahoma counties continue to be under a burn ban Labor Day weekend. The state-wide ban was signed by Governor Mary Fallin due to "an extreme and extraordinary danger from fire."

It is prohibited for anyone to build a bonfire or campfire, burn or ignite fireworks or burn trash and other materials outdoors. Organized public fireworks displays may still proceed with the approval of the local fire department of State Fire Marshal's Office, according to the State Forestry Department.

The ban permits gas and charcoal grilling as long as it is over a nonflammable surface like concrete or gravel and at least five feet from flammable vegetation. 

Be sure to have a water source on standby.

There are exemptions for a number of items such as welding and road construction. See complete list of prohibited and allowed activities under burn ban.

Oklahomans are asked to use extreme caution with lit cigarettes, flat tires and cars parked in dry grass – all of which can spark grass fires.

Anyone who sees a grass fire - or suspicious activity involving fire - is asked to report it immediately.
