The 3M DBI SALA RoofSafe Anchors are designed by Capital Safety is a complete fall protection system, which means that it provides work restraint as well as fall arrest when completing tasks at height. While all roof anchors must provide fall arrest as a feature, ideally the product would also have work restraint capabilities to preemptively remove much of the risk of falling from height. This is done by restricting the roof space the worker has access to through the use of lanyards, therefore removing their ability to access roof top areas from which they are liable to fall.
Including both fall arrest and work restraint creates an all around product which restrains the user while they work and stops their fall should it be required as well.
Work restraint systems have many advantages over the use of a solely fall arrest based system, which include:
When asking for a quotation for a work restraint system such as the Uniline RoofSafe Anchor, a scale drawing should always be provided. This is so the appropriate length of lanyard can be calculated into the costs for the job. Ensuring that the lanyard is short enough to prevent the worker using the system entering any points of the roof a fall might occur in is one of the key design elements that need to be taken into consideration.
The 3M DBI SALA RoofSafe Anchor is a specialist piece of equipment and should only be installed on site by a qualified technician.
A Site Survey should be conducted before installation; this is so that the type of system required can be specified as well as allowing the surveyor to see where the system is going to be fitted and plan accordingly. In order to create an effective plan for installation, the following information should be gathered at the survey stage:
Before the work is carried out, in light of the information given above, a method statement should be drawn up. This is so that there is a concrete, agreed, step by step account of what will be happening during the installation process. A method statement document is key in protecting the client involved in the work as well as the company performing the install.
When installing the 3M DBI SALA RoofSafe Anchor it is important to select a location where the individuals using the product can access it safely. The entry point to the system must be somewhere there is not a risk of a fall from height, if this is not possible based on the roofing type or design a secondary type of fall protection should be used to ensure the workers safety before they clip onto the 3M DBI SALA RoofSafe Anchor system. Exit points for the system can be in the same location as the entry points, but, should they differ and the exit point is also in a fall hazard area other fall protection systems should be used there also.
Swing falls can be deadly, especially when working near a gable end. The image below shows that while the lanyard in one situation is enough to prevent a fall and suspend the user, in another because it was near the gable end of the roof the lanyard had too much excess length and was unable to save the user from injury. Swing falls are also dangerous for workers using equipment because of the slicing effect that moving across the roof edge will have on the lanyard being used. If the slicing effect is large then it could result in the lanyard being severed and a fall occurring. This can be avoided by installing edge protection to prevent falls over the edge of the roofing.
There are currently two types of anchor within the range, the SpiraTech Anchor and the Tip Over Anchor. Both of these anchors allow for 360 degree movement for workers utilizing the system – both also have the feature of allowing for work restraint as well as fall arrest when used in conjunction with the proper personal protection equipment for working at height. In both models of anchor the baseplate, module and top attachment can be chosen to match the requirements of the individual’s project needs and to suit any roof membrane on which the system might need installing.
Employers have a responsibility to make arrangements for emergency situations wherein a rescue might need to take place. Following a fall there should be a rapid response to remove the worker involved from the dangerous situation – in order for this rapid response to take place. Before the use of the system an emergency plan in the case of a fall should be created and all workers informed of said rescue plan. The appropriate equipment will be needed on site in case a rescue needs to take place, Training is also important, so that employees are aware of what to do in rescue situations.
Looking at the strength of the 3M DBI SALA RoofSafe Anchor in greater depth, the product has been designed to have the internal supports break away from the covering when subjected to a force of less than 3kN. This allows the element of the 3M DBI SALA RoofSafe Anchor which absorbs the energy to take the full force of the fall. Once this element of the anchor has been deployed it then reduces the amount of the force put on the user and the roof on which it is installed. As soon as the user has been brought to a resting position after the fall, the anchor can withstand twice the load of the peak arrest for three minutes which conforms to the European Standard for protection against falls from height for anchor devices.
As previously mentioned the 3M DBI SALA RoofSafe Anchors can be pull tested with a strength up to 5kN without compromising the integrity of the product. These tests should be conducted once a year to ensure that the anchor has developed no faults and continues to be an effective system for use as fall protection and work restraint. While tests need to be done to the roof anchor itself annually, there also needs to be Compliance Inspections conducted on the swages which are responsible for ensuring that the cable is attached securely to the roof anchor.
In some circumstances cleaning might need to be done to the product. The 3M DBI SALA RoofSafe Anchor is naturally corrosion resistant thanks to the alloy material from which it is made and all exposed areas of the anchor have been made of this alloy or covered with sacrificial coatings in order to prevent rusting of the base material. Cleaning the anchor, if it is being kept in certain elements, may need to occur despite this in order to get the best possible life expectancy from the product.
The 3M DBI SALA RoofSafe Anchor is a product which combines the necessary fall arrest requirements for work at height alongside the ability to support an employee using the anchor by its work restraint features. When preparing for an installation of the anchor it is important to have as much information as possible such as where the system is being fitted, the risks that need to be taken into account when fitting the system and what roof type the building the 3M DBI SALA RoofSafe Anchor is being installed on.
