Knowing where the key to the main building is located is critical when it is time to react to flooding. But if you tell everyone where the hidden key is, it’s no longer hidden. Part of your plan should be to identify and notify personnel who need to know where the keys to each building are located.
Depending on who arrives first, knowing where the keys to the important buildings are hidden allows for an earlier response as others are called to the facility. And when you leave a facility before a flood, be sure to leave the doors to all buildings open. Although this may sound counterintuitive to business owners, leaving the doors open can help prevent floodwaters from causing structural damage.
