What dilution of ethylene oxide with water is required to effectively inhibit its
flammability? - Correct answer-24: 1
Once ethylene oxide becomes contaminated, what kind of chemical process may occur
that can generate enough heat and pressure to rupture its containment? - Correct
answer-Polymerization

- Correct answer16. Firefighters often apply a hose stream to the side of a building that is in close
proximity to a fire. What is the primary reason for conducting such an operation? -
Correct answer-Radiant heat given off by the neighboring fire may adversely affect the
nearest wall. Without the coolant effect of the hose stream, enough heat may be
absorbed by an exposed surface to cause ignition and create a separate blaze.
17. Frequently, people use an octopus wall outlet connection to maximize the number of
appliances that can be plugged into a single outlet. What would this be considered? -

possible when in the vicinity of power lines.
**Any kind of metal ladder poses an electrical hazard if it comes into contact with an

22. Icy road conditions can be particularly hazardous for driving because - Correct
answer-Friction between the tires and road is minimized.
**Brakes, contrary to popular thought, are not directly responsible for stopping a vehicle.
Instead, they retard the motion of the wheels. Consequently, friction develops between
the tire and the road which is directly responsible for a vehicle coming to a complete
stop.**
