Question 7

Placement of Flares

Answer 7

1. Since every accident/hazardous highway situation is different, it is difficult to
   develop a standard placement pattern. The type of accident, roadway, weather
   conditions, and safety factors must be considered when placing flares.
   a. Determine a sufficient warning distance for approaching vehicles by placing
   flares approximately 25 feet apart nearest the accident scene and gradually
   increasing the distance from 50 to 100 feet apart at the farthest distance needed.
   b. Place flares to direct traffic to one lane if possible. If traffic must change lanes,
   a gradual angle of alignment pattern will be used.
   c. During accident or hazardous highway situations, check for possible fire danger
   before lighting or placing flares.
   d. Do not use flares near gasoline, butane, or other flammable substances.
   e. Flares will not be used at chemical spills until the Fire Department is able to
   evaluate the chemical composition.
   f. On new highway construction, the use of raised pavement markers (BOTTS
   DOTS) and lane lines of plastic stripes have created a possible fire hazard.
   Flares should not come in contact with these objects.
   g. Once the roadway is cleared, the flares should be extinguished except those
   needed for the obstruction on the shoulder.
