Sometimes the windows are barred too, but not always. Usually if the front or main entrance is barred, then additional front or rear entrances will be barred too. Our companies doing truck work are not as consistent about removing bars from windows during offensive firefighting as they should be; but I wanted to just share a common occurance with security bars on residential entry and exit doors. Ideally, the RIT company should remove any additional bars from windows and doors during the firefighting operation, but this doesn't happen near as often as it should. Thanks!
