Exit routes must be sufficiently large and adequately signposted.Which of the following is another requirement that exit routes must meet? Select the best option. All emergency signs should be red All doors along the exit route must be unlocked The exit route must lead to an interior room

## Step 1<br />The problem is asking us to identify another requirement that exit routes must meet, in addition to being large and adequately signposted. The options provided are:<br />- All emergency signs should be red<br />- All doors along the exit route must be unlocked<br />- The exit route must lead to an interior room<br /><br />## Step 2<br />We need to consider the practicality and safety implications of each option. <br /><br />## Step 3<br />The first option, "All emergency signs should be red", is not a requirement. While red is a common color for emergency signs, it is not a strict requirement. The color of the signs can vary depending on the jurisdiction and the specific regulations in place.<br /><br />## Step 4<br />The second option, "All doors along the exit route must be unlocked", is a practical requirement. This ensures that people can quickly and easily access the exit in case of an emergency.<br /><br />## Step 5<br />The third option, "The exit route must lead to an interior room", is not a requirement. In fact, it could be dangerous as it could trap people inside during an emergency.
