Stainless steel

Corrosion of safety line components can cause unsightly rust stains to appear on the roof sheets. In extreme cases it can cause loss of the integrity of the system as a whole.

More worrying are the effects of hidden corrosion, often this will only become apparent when needed the most, in a fall situation.

It is a common belief that the various protective surface coatings available offer sufficient resistance to corrosion, but this is not the case.

Protective coatings applied to carbon steel elements will only offer temporary corrosion protection.

SFS understand the problems associated with metals when exposed to the elements, especially Safety lines that are exposed to the weather 365 days a year.

Corrosion is measured in terms of loss of performance that could be catastrophic in a fall protection system. Safety lines cannot afford to lose performance.

EN 795:2012 requires all components to be subjected to a neutral salt spray test in accordance with EN ISO 9227 for a period in excess of 48 hrs.

After testing metal parts cannot show any evidence of corrosion.

All components within the SFS Horizontal Lifeline System including internal absorbing elements of the post use a combination of both 304 and 316 stainless steel giving peace of mind to the end user or building owner that any installed SFS system will have a lifespan equal to or beyond the building life.

System maintenance

Safety line systems must be inspected and re-certified at intervals not exceeding twelve months. This is a requirement of EN795:2012.

Horizontal line systems are affected by changes of temperature that will result in expansion/contraction of the wire. Where systems are subject to significant seasonal temperature variations, these will require re-tensioning for summer and winter operation.

Only those components manufactured and supplied by SFS are permitted for use. The exceptions to this are bespoke fittings required to attach the system to particular structures. Wherever possible such bespoke fittings should be designed and manufactured by SFS, or their design approved. Where such bespoke fittings are provided from another source, it is the installer company’s responsibility to ensure they are fit for the purpose intended and carry the necessary approvals.

Under no circumstances must a standard Soter component be modified or replaced by components from another source.

It is important that all Soter devices will align themselves correctly through all componentry; and that there are no obstructions or structures that interfere with the Slyder device or deflect the wires path.

The structure to which Soter systems are to be installed should be sufficiently strong to withstand the fall arrest/restraint loadings for which the system is designed. These loadings can be calculated by the installer or provided by SFS. If there is any doubt as to the structure’s ability to withstand such loadings, then the system should not be installed without appropriate testing on the substrate.
