IAFF Training for Hazardous Materials: Technician© Student Text 7-88 Module 7: Personal Protective Equipment
Student Text IAFF Training for Hazardous Materials: Technician© Selecting CPC Activity 6 Several brief scenarios are described below. Read each one aloud to the students and have them identify the appropriate level of personal protective clothing that would be necessary for safe entry; Level A, Level B, or Structural Fire Fighting Clothing (SFFC). Ask them the reasons for their responses. For the purposes of this exercise, assume that: • Level A is equivalent to fully-encapsulated vapor protective clothing • Level B is equivalent to liquid splash protective garments Remind the students that EPA levels C and D are not appropriate for emergency response. An explanation of the answers appears on the following page. Scenario 1.An ammonia cloud forms after a tank truck accident. Haz mat team members must enter the area to plug the leak. There are high concentrations of ammonia in the immediate vicinity. Level A Level B SFFC Entry is Not Safe 2.A reconnaissance team comes into an abandoned hazardous waste site containing hundreds of open drums and two large waste lagoons. There is no vegetation and a dead dog lies near the boundary. No other information is available. 3.Fire fighters respond to a large sodium fire in a metals processing establishment. The roof collapses as fire fighters arrive. The sky is cloudy, and a thunderstorm is imminent. 4.A 55-gallon drum of nitric acid is damaged when it falls off a loading dock at a chemical facility. The acid is leaking slowly and running toward a storm sewer. 5.A gasoline tanker has overturned on a busy interstate and a small amount of gasoline has spilled into a ditch. The leak appears to have stopped because the remaining liquid is below the breach. 6.A truck carrying several drums of pyrophoric aluminum powder is involved in an accident on a city street. Several drums are damaged and some powder has spilled. 7.A train carrying low level radioactive waste uranium is one of several cars that derail during an accident at a rail yard. There is no fire, but several people are injured and must be rescued. 8.A tractor trailer carrying a load of phosphoric acid swerves and the load shifts, spilling several gallons of the acid. The driver is still in the cab, injured. 9.Fire fighters respond to a small fire at a garden center. The fire has extinguished itself when they arrive, but several containers of organophosphate pesticides have been damaged. Two employees have been injured and are in the area of the fire, unconscious. Module 7: Personal Protective Equipment 7-89
