MSA Latchways ManSafe Constant Force® Fall Arrest / Restraint System

Guided type fall arrest system using a cable attached to Constant Force® anchor posts. Provides individual protection, requiring direct action by each user to ensure they are protected. Must be used with personal protective equipment (PPE), e.g. full body harness to BS EN 361, energy absorber to BS EN 355, and lanyard (of correct length) to BS EN 354. PPE procurement is normally the responsibility of the building owner/ user.

The level of user competency required to safely use different categories of system varies:

• Perimeter system: Fall restraint; no PPE adjustment necessary; basic user training required.
• Perimeter system with fall hazards in addition to roof edge (weak rooflights, vents, etc): Fall arrest; no PPE adjustment necessary; basic user training required.
• Ridge system: Fall arrest; PPE adjustment necessary; advanced user training required. Not advised for roof pitch greater than 25°.

Note that perimeter systems generally do not give blanket coverage of a roof. If this is required, and a ridge system is deemed impractical/ unsuitable, then a series of interconnected systems must be installed, covering the full width of the roof.

Components are designed for compatibility with most roofing systems; Latchways technical literature gives specification details for the following:
