If building occupants are not evacuated before a hurricane, what should they be instructed to do during the hurricane?

Staying indoors and away from windows and glass doors during a hurricane is the best course of action for building occupants who have not been evacuated. This is crucial for safety because hurricanes can produce extreme winds and flying debris that can shatter windows, causing injury from broken glass and projectiles. By taking refuge in interior rooms or areas of the building, occupants can maximize their protection from the storm's effects.

Keeping away from windows helps to minimize the risk of being harmed by any debris that might enter through broken glass. Additionally, staying in a secure part of the building can provide a buffer against potential structural failures that might occur during such dangerous weather conditions.

Other options, such as evacuating to the roof or standing in the hallway, pose significant risks. The roof is potentially the most dangerous place during a hurricane, as it exposes individuals to the elements and the risk of being swept away. Standing in the hallway does not offer adequate protection from flying debris and may not necessarily be in a safer location compared to staying in a secure interior space. Gathering in the parking lot exposes individuals to the full force of the storm and debris, which could lead to injuries or fatalities. Overall, staying indoors is the most effective method to ensure safety during a hurricane.
