Chief Officer Training Curriculum

1. Chief Officer Training Curriculum Operations Module 17: Grain Elevator Simulation Exercise

2. Objectives • Identify the critical cues required to manage a grain elevator incident • Establish incident objectives • Determine strategies • Select tactics

3. Objectives (continued) • Identify and request resources • Select alternate solutions • Establish an appropriate ICS organization to manage the incident

4. Overview • Grain elevator construction • Incident considerations for grain elevators and grain dryers • Fire extinguishment in grain elevators • The normal causes or sources of ignition for fire or explosion

5. Grain Elevator Construction • Offices • Silos • Head house

6. Grain Elevator Preplan • Complexity • Egress • Machinery • Explosion potential

7. Dust Explosions • Small initial explosion • Second explosion—larger, more powerful • Operations should never disturb large amounts of dust

8. Grain Dryer Incident Considerations • Dryers fueled by propane, fuel oil or natural gas • Safety features • Discharge chute clogging • “Hot” grain • Large fires difficult to control

9. Grain Elevator Fire Extinguishment • Apply water slowly and gently • CO2 sometimes injected from bottom • Interior offensive attack should be done with caution • Protective equipment required to enter grain bin, tank, or silo

10. Grain Elevator Sources of Ignition • Bearing friction • Rubber conveyor belt • Belt/friction slippage • Faulty electrical wiring
