Question

what step of fire extinguisher operation is shown in the image? select one: a. aim the nozzle. b. squeeze the pin. c. squeeze the nozzle. d. squeeze the handle.

Explanation:

To determine the fire extinguisher operation step, we analyze each option:

• Option a: "Aim the nozzle" involves positioning the nozzle at the fire, but the image shows the extinguisher discharging, so aiming is likely done before.
• Option b: "Squeeze the pin" is incorrect terminology (the pin is pulled, not squeezed).
• Option c: "Squeeze the nozzle" is not a standard fire extinguisher operation step.
• Option d: "Squeeze the handle" is the step where pressure is applied to the handle to discharge the extinguishing agent, which matches the image of the extinguisher releasing the agent (as the person is squeezing the handle - like mechanism to activate discharge).

Answer:

d. Squeeze the handle.
