Openings<br />
in tin plated roofs.<br />
Always<br />
observe care<br />
when creating<br />
openings,<br />
especially when<br />
working on the<br />
roof!<br />
for the crew and the need for special tools. If the fi re fi ghting<br />
crew has the right equipment and the roof structure<br />
permits an opening to be made quickly, the fi re gases and<br />
fumes can in all probability be vented out enough to simplify<br />
the work of fi re fi ghters.<br />
On the following pages there is a description of the common<br />
tools used to create openings in the roof, and examples<br />
of openings made in different roof structures commonly<br />
found in Sweden. Unconventional measures, such as for<br />
example demolishing walls/roofs with the help of excavators<br />
or crane lorries are not considered. In certain cases<br />
these methods may very well provide suitable solutions to<br />
tactical problems, but they should be used with a certain<br />
degree of caution.<br />
Tools for creating openings in the roof<br />
The tools shown are generally available at the fi re and rescue<br />
services, and are used for the purpose of creating openings.<br />
They are divided up into electric motor powered tools,<br />
internal combustion engine tools, hand tools, and special<br />
equipment.
