Safety equipment


integrated part of both the conventional fire belt and the seat harness in the Rescue Suit 90, which is used by the Swedish fire and rescue services. The connecting line to the fire belt consists


of a chain with attendant spring safety hook. The applications for both of these items of equipment are rather limited for obvious reasons, as primarily it is a matter of securing yourself when you are working on a ladder, a mast or such like. To achieve a larger working area on the roof, it is possible to use a ladder truck as an anchor point for a line, a sling or a fall protection block.


Work without ladder trucks Another situation commonly experienced is working on roofs where it is not possible to secure to a ladder truck, or where for practical reasons it is necessary to leave the ladder or ladder truck in order to work more freely over a larger area. In this case, an anchor point is needed to fasten the line, sling or fall protection block. This point must be able to withstand the resulting force if the person should fall. Such an anchor point could be a chimney, a roof ladder or a rail. In addition, a safe escape route should be


created if possible, for example by placing and anchoring a ladder on the roof, and as far as possible this should be used as a work platform.


When actually creating the roof opening,


this should be carried out in such a way that there is always a safe escape route. The first cut in a roof should be made away from the work platform (ladder or ladder truck), so that the last cut can be made while standing on the work platform. It may be advisable to establish some form of standard operating procedure when working at high altitudes, the intention being to create a safe escape route and a safe work platform.


Creating openings


Openings are an essential part of work to facilitate fire ventilation, and the methods by which openings are made manually by means of hand tools are considered here. Explosive cutting frames and water cutting are methods that require special training and special equipment, and will only be considered in general terms. There are no general methods for creating openings in roofs during fire ventilation in a fire and rescue operation (with the exception of explosive cutting frames and water cutting, which can be utilised in a number of different situations). However, there are a large number of suitable tools that can be used, and certain guidelines are available that can be suggested for creating openings in several common types of roof structure.
