Lifelines are not a new concept for us; we have already talked about them in previous posts, covering their definition, characteristics, and types.
This time, we are going to take a closer look at what a lifeline inspection involves, both routine and long-term, and its periodic reviews.
Parts of a Lifeline
Lifelines are fall arrest safety devices normally installed on roofs and inside industrial buildings. They are designed so that, in the event of a fall, the user does not hit the ground but instead hangs from the cable, which is normally made of steel.
These systems consist of:
- Energy absorber
- Cable
- Anchor point
- Sliding device or trolley
Besides these elements, a safety harness and a lanyard or cord are also needed to connect to the lifeline.
All parts and accessories of this fall arrest system require maintenance and inspection; we are going to focus on the inspection of the fall arrest lifeline itself.
Lifeline Deterioration
Lifelines, like any other device, deteriorate over time, regardless of the area or location where they are installed.
The material chosen to manufacture the system must be taken into account in this deterioration: a galvanized steel lifeline, which deteriorates much sooner when installed outdoors due to changing weather conditions, is not the same as stainless steel, a material that lasts much longer.
On the other hand, when they are installed indoors in industrial buildings, factories, or warehouses, the conditions of each location must be considered; for example, there may be gases that accelerate damage to these systems.
Ultimately, the material and installation location of a lifeline must be studied in detail, choosing what is most suitable for each project.
Lifeline Inspection
Besides the deterioration of a lifeline over time, other aspects must be considered to keep this safety system effective.
A series of inspections must be carried out by qualified personnel to ensure the safety of the lifeline:
Visual Inspection
This inspection must be done every time a lifeline is about to be used. Before using it, check for any damage or wear, and verify that it is securely fastened and that there are no irregularities.
As part of this check, the following elements of the lifeline must be examined:
- The cable, looking for knots, cuts, excessive wear, etc.
- Connection components such as carabiners or hooks, making sure they are in good condition and the closures are secure.
- The energy absorber, checking that it has not been activated.
If anything is out of the ordinary, the system must not be used and the person in charge must be notified.
In addition, before using the system, it would be advisable to run a test or simulation to confirm that everything works safely and that the system is properly adjusted.
Annual Inspection
Lifelines are fall arrest systems governed by the UNE-EN 795C standard; on that basis, the reviews or inspections it requires must be carried out.
The standard says that inspections must be done at least every 12 months, but the manufacturer of the system may reserve the right to change this and shorten the inspection interval; for example, there are manufacturers that set a maximum interval of 12 months.
Keep in mind that if the interval set by the manufacturer for inspection is exceeded, the system is no longer covered by the warranty and may not be safe.
These inspections and tests carried out on the lifeline must be recorded in an inspection document, including the date, the inspector’s name, and any action taken if problems are found.
Inspection After Use
When an accident, mishap, or error occurs while a lifeline is in use, the entire fall arrest system must be inspected.
For example, the most extreme case is when an accident has occurred and the energy absorber has been activated; it must then be replaced.
In conclusion, inspecting and maintaining a lifeline is essential to ensure the safety of the users of the system. The manufacturer’s recommendations and intervals must always be followed, in addition to the regulations.
