Guide Lines:
A small diameter line for the purpose of allowing subsequent BA teams
to proceed directly to a fire in a smoke logged building by following the route
of the line while attached to it via a snap hook. A Personal Line is housed in a
small bag attached to the set and is 6 metres long, with a loop 1 metre from the start.
Main Guide line is housed in a bag carried on the set which pays out the
line as the team advances. It is 60m long with ordered metal ferrules located at
3 metre intervals. These ferrules allow the team to tell by touch if they heading
to the fire or the exit. Personal lines are used to attach to this line.
Guide Line Tallies are used to identify a Guide Line during an incident.
Main Guidelines are attached externally to the building, and a Main Line Tally,
lettered A or B is then attached to the start of the line. Branch Line tallies,
numbered 1 to 4 are used internally and are attached to a point along the
Main Guideline. These have holes stamped in the tallies to indicate the number
so they can be identified in poor visibility conditions.
