Which system should you choose?
Anchor points and static lines are two different systems that achieve the same purpose: protecting personnel and contractors from falls. Each system has its pros and cons, as well as appropriate and inappropriate times for use.
To determine which would be best for you, you need to fully understand your specific situation and ask yourself these questions:
- How many people will be working at heights?
- Are they going to be bound to one location?
- How frequent will the movement around the roof be?
- How big is my roof?
- What is the pitch of my roof?
- What is my budget?
It is possible that by answering these few simple questions, which system to use will be obvious.
How many people will be working at heights?
The fastest way to determine which system to use is the number of people working at heights. Typically, an anchor point is rated for one person if it is a 15 kN anchor and for two persons if it is the 21 kN anchor. If you want to allow access for one person working at heights, then having anchor points is the way to go. However, to protect an entire crew, you would need to consider static lines.
Are roof workers bound to one location?
If every employee is bound to their own work location, then anchor points are the way to go. If multiple employees are working and need to move around to help each other or bring supplies, or just move on to the next section of work, your best solution in this case is a static line. A static line would allow much more freedom of movement while still protecting your employees.
What is the pitch of my roof?
If the roof pitch is less 30 degrees then both anchor points and static lines can be considered. If the roof pitch is more than 30 degree and less than 40 degrees then fall arrest anchor or rope access anchors can be considered. If the roof pitch is more than 40 degrees then the only option is having abseiling rope access anchors.
Which system would be more cost effective?
If you have a big sized industrial warehouse roof, then static lines are the way to go. They are more cost effective as they require less fixtures to the roof in bigger sized roofs. You can also mix between anchor points and static lines and install anchors in smaller areas and install static lines in bigger areas.
Conclusion
By brainstorming and going through these questions you are probably able to figure out which system is right for you anchor points or static line.
