Brotherhood Instructors - Opening Scuttles and skylights are a quick and easy way to provide vertical ventilation. Once the scuttle or skylight is ventilated the roof firefighter should open the vertical surface between the top floor ceiling and the roof -- known as the returns. This will allow the roof firefighter to see into the cockloft and gain valuable information such as roof construction type and if fire has entered the cockloft. If lightweight construction components or fire in the cockloft is discovered be sure to radio the findings to your company officer or incident commander.
