Video displays the combined operation of an Escape Sleeve with the Portuguese-style Hooks Ladder. Footage shows a training episode, probably dating from the 1970’s decade, performed at the HQ of RSB-the fully professional municipal FD of Lisbon, Portugal (note the old style leather helmets which were standard issue at the time).
The escape sleeve (a 1808 Swiss patent) was adopted by the RSB in 1838 and was discontinued by this FD in the 1990’s decade. Made of canvas and measuring 79 feet (with 3, optional, exit ports) the sleeve was used for evacuating residents from burning buildings, out of a window or a balcony. It was carried in all Engines and required 5 or 6 men for operation (1 FF would carry on his back the upper portion), using a conventional ground ladder (spring-type, by sections) or a Hooks Ladder.
The Portuguese Style Hooks Ladder, which can be seen in this video, was traditionally made of wood (with iron hooks) and may be probably considered as a variant of the pompier ladder that was once used in the USA and in Europe. It measures 14 feet and is folded by the middle for transportation purposes. It was carried in all Engines as well as in Rescue and Utility units on a time when ladder trucks were expensive and rare pieces of apparatus in Portugal... It is less used these days (although mandatory part of Cadets/Probies training) and modern models are made of aluminum.
