When the water supply has been disrupted due to a natural disaster, an acceptable alternative...

A disruption in the water supply is considered animminent health hazard. Because water is essential for handwashing, cooking, and sanitizing, an establishment cannot operate safely without a potable (drinkable) source. According to the ServSafe Manager curriculum, if the municipal supply fails, the only acceptable short-term alternative5for drinking and food preparation iscommercially bottled drinking waterfrom an approved source.

Other options are highly unsafe: a 50-50 bleach mixture (Option B) is toxic and would cause chemical poisoning. Private wells (Option C) must be tested at least annually, not every two years, and may not be sufficient during a disaster. Water from an air conditioning system (Option D) is non-potable and potentially contaminated with mold and chemicals. If an establishment uses bottled water, it must also address other needs, such as using single-service (disposable) plates and utensils to avoid the need for dishwashing and providing portable handwashing stations or hand sanitizer (though the latter is only a temporary measure). If safe water cannot be secured for all essential tasks, including restroom use and handwashing, the manager must close the operation until the water supply is restored and cleared by the regulatory authority.
