Which of the following is an example of passive laser protective measures?

Taking cover is considered an example of passive laser protective measures because it involves physically positioning oneself behind a barrier to prevent direct exposure to laser radiation. This method does not rely on active engagement with the source of the laser or attempting to evade its path; instead, it focuses on minimizing risk by using the environment as a shield.

Passive measures like taking cover are crucial in environments where lasers may be present, as they provide a straightforward way to protect crew members without requiring them to move or respond dynamically to the threat.

Looking at the context of the other options: evasive action involves actively moving to avoid the laser, which is an active protective measure rather than a passive one. Scanning with one eye is more related to visual techniques but does not offer physical protection against laser exposure. Infrared goggles, while useful for enhancing vision in low light conditions, are considered an active protective measure designed to specifically counteract the effects of laser light rather than being a passive way to shield oneself.
