Tactical Scenarios
at the municipal golf course. A single engine com- pany was dispatched to the clubhouse to investi- gate. Upon arrival, the engine company officer confirmed that there was a hydrocarbon odor both inside and outside of the clubhouse, which was closed to the public for remodeling. The engine company officer proceeded to check the atmosphere with a CGI and could find no abnormal readings.
Having cleared the clubhouse, the engine com-
pany officer decided to drive along a maintenance road paralleling the golf course to see if he could de- termine the source of the odor; about ½ mile from the clubhouse the officer observed a large cloud of steam coming from an area on the golf course. Using binoculars, the officer noticed a very large area where the snow had melted and was colored brown. The hydrocarbon odor was noticeably stronger in this area, and the officer had another CGI reading taken. The engine company officer then or- dered two firefighters to don their PPE and investigate the area where the snow had melted. As the firefighters closed in on the area, the CGI readings increased to 2% of the LEL, and then 5% of the LEL. At this point, the engine company officer ordered the firefighters to withdraw.
Upon returning to the engine, the firefighters reported that the size of the
spill of the brown liquid on the golf course was in fact much larger than it ap- peared from the roadway, and was gurgling up and out of the ground and leaking into a drainage ditch that flowed toward a frozen pond on the golf course.
The engine company officer then consulted his map book for the area and
discovered that a 24-inch liquid transmission pipeline passed along the golf course. With this information, the engine company officer requested that the fire department hazardous materials officer be sent to the scene.
At 3:10 P.M., the fire department hazardous materials officer arrived at the
scene, surveyed the spill area, and contacted the Pipeline Control Center. The hazmat officer was teleconferenced with two pipeline company supervisors and they confirmed that their data indicated that the pipeline had ruptured and that the line had been shut down and closed in. They also confirmed that the product was crude oil. Having confirmed the exact location of the spill, an emergency r8pair crew was dispatched to the scene. See Figure 7.28.
INCIDENT ACTION PLAN Tactical Objectives
The primary tactical objectives are to (1) isolate the area and deny entry, (2) establish a unified command organization between responding agencies, and (3) develop an Incident Action Plan to confine the spilled crude oil and control ignition sources.

Figure 7.29 Pipeline Control Centers can monitor pipeline flow rates, pressure, and other parameters that can indicate a rupture in the line.
