6. Dehydration
Dehydration occurs when the amount of water in the body falls below normal, which can disrupt the balance
of sugars and salts (electrolytes).

7. Sleeping
Lack of sleep my lead to microsleeps—a brief episode of sleep which can last anywhere from a fraction of a second up to 30
seconds. During a microsleep, you are temporarily unconscious.
If lack of sleep continues, the body builds a “sleep debt” for every hour of lost sleep. Getting extra sleep can reduce the debt, but if
sleep deprivation becomes long term, it may not be possible to reverse the effects.

11. Why is vigilance a critical element of
security?
A state of readiness to react
‫للرد‬ ‫االستعداد‬ ‫من‬ ‫حالة‬
Helps identify risks
‫المخاطر‬ ‫تحديد‬ ‫في‬ ‫يساعد‬
vigilance is the critical factor in human performance. Defined as "a state of readiness to react",
vigilance is what enables us to identify risks and take appropriate action to manage them.
Without vigilance, all the training and experience in the world will not protect you.
Take appropriate measures to manage the situations
