2.Safety solutions
Example Conditions of application
Effects
Collective protection
nets, barrier nets Long period building works
Stops the user before he falls
Work positioning system
Lanyard, belt •Intervention of less than 1 day•Imperfect collective protection
The potential fall has to be < 1 m.Foresee the security of the access to the work station
Fall arrest system
Lanyard with absorber, retractable fall arrester…
•Intervention of less than 1 day•Unperfect collective protection•Technical operations on at height, on rope
The potential fall can be > to 1 m, but the system must restrict the effects on the user.
Safety solutions’ comparative table
3.Fall arrest systemSummary
•Definitions
•The body support
•The fall arrester
•The connection
•The anchor
3.Fall arrest systemComponents associations
Anchor point
Fall arrester
Body support system
Equipment that secures one user at an anchor point in order to avoid any fall from height or to keep him in safety conditions.
Definition
The anchor has to be positioned above the user
3.Fall arrest systemShock impact
Shock impact
When a fall occurs, the user supports a shock impact with possible injuries.
400 kN threshold value for cervic bruising
600 kN threshold value acceptable for the human body
1000 kN maximum limit : severe bruising – lethal risk-
3.Fall arrest systemDefinitions
Clearance (T)
Distance between the anchor point and the nearest obstacle.

3.Fall arrest systemWork positioning system
A work positioning system gives to the user the possibility to work in a certain way (potential fall).
This equipment is never used as a fall arrest system
Allows safe completion of task
