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.

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.
