Question

which strategies are effective for addressing visibility challenges during surveillance? select three answers.
change your body position if needed to see around blind spots, glares or distortions
wear glasses with polarized lenses to manage glare
reposition your chair anytime you think it’s needed in order to see better
if something doesn’t look right at the bottom of a pool, assume there is a body there
get up and move from your elevated station to a different area if the sun is in your eyes

Explanation:

1. "Change your body position if needed to see around blind spots, glares or distortions" – Adjusting body position helps in getting a better view by avoiding obstructions or glare angles.
2. "Wear glasses with polarized lenses to manage glare" – Polarized lenses are specifically designed to reduce glare from reflective surfaces, which is effective for surveillance visibility.
3. "Reposition your chair anytime you think it’s needed in order to see better" – Repositioning the chair changes the viewing angle and distance, aiding in better visibility.

The option "If something doesn’t look right at the bottom of a pool, assume there is a body there" is incorrect as it's a baseless assumption, not a visibility strategy. "Get up and move from your elevated station to a different area if the sun is in your eyes" – While moving can help, the first three are more directly about managing visibility challenges during surveillance.

Answer:

1. Change your body position if needed to see around blind spots, glares or distortions
2. Wear glasses with polarized lenses to manage glare
3. Reposition your chair anytime you think it’s needed in order to see better
