INSTALLATION
3.1
PLANNING: Plan your Fall Protection system before installation. Account for all factors that may affect your safety
before, during, and after a fall. Consider all requirements, limitations, and specifications defined in these instructions.
Additionally, the following points should be considered when planning your system:
•
Anchorage: Select an anchorage capable of sustaining the Static Load requirements of the intended Fall Protection
application. See the manufacturer instructions for each component of your Fall Protection system for more
information. The anchorage location should address all limitations described in Section 1.4.
•
Sharp Edges: Avoid working where system components may be in contact with, or scrape against, unprotected
sharp edges and abrasive surfaces.
•
After a Fall: If the Full Body Harness is subjected to fall arrest or impact force, remove the Full Body Harness from
service immediately. Clearly tag the system "DO NOT USE". See Section 5 for more information.
•
Rescue Harness: Rescue Harnesses are intended to be worn during normal work activities. Before using rescue
attachment elements for the first time, the user should carry out a suspension test in safe conditions to ensure the
harness is sized and fitted for optimal comfort during suspension.
