ELSR Safety lines
How to use
The minimum utilization height required for every ELSR safety line configuration is equal to Tmin= 8mtrs (from the ground to the user's floor surface).
[ Tmin = 8mt ]
Such minimum utilization height has been created by considering the following:
height of the Columns,
maximum line lowering caused by a possible falling,
maximum length to be reached by commercially provided energy absorbers,
minimum space required between the user's feet and the ground, after falling.
Edilmatic Safety Line Users have to wear slings and energy absorber equipped with twofold cord, both reporting a CE marking (UNI EN 355 - UNI EN 361); we remind that a lot of types of energy absorbers being equipped with different air draught elements can be found in the market.
In a logic of a protection of the user, Edilmatic's requirement (Tmin=8mtrs) refers to the worst condition which could occur. The minimum utilization height (which shall never be lower than 5.35mtrs) shall be evaluated by considering the minimum air draught required for the energy absorber worn by the user, the maximum system line lowering as well as the height of the columns. To avoid mistakes, a determination of the utilization height of the safety line shall consider the formula reported here below:
Tmin = Ta + 1 ......which means
Tmin = minimum utilization height
Ta = air draught element required for the energy absorber worn by the user
1 = maximum line lowering in ELSR10-20 lines
0.8 = column height.
Example of minimum utilization height (Tmin) with the employment of accessory equipment (Connector Cord, Energy Absorber etc ...) (energy absorber extension after falling = 0.7mtrs)

Example of minimum distance from the ground with Cord and Energy Absorber Lt = 1.15mtrs
(energy absorber extension after falling = 0.7 mtrs)
