Fall protection

Falling from heights is one of the most occurring causes of fatal occupational accidents. When working at heights of more than e.g. 2,5 meters, many legislators require to secure workers to prevent them from falling. Examples are fall restraints, avoiding workers to reach dangerous positions.

In circumstances where for example handrailings cannot or may not be installed, then McNetiq Controlock® magnets can form a safe and secure basis to attach lines for fall restraint purposes. This connects to a lanyard with harness, and prevents a worker from reaching unsafe areas.

Working safely with magnetic anchors

With McNetiq Controlock® magnetic anchors, fall restraining positioning lines can be safely secured. This is especially applicable in circumstances where permanent fixing point can or may not be used

For a safe use it is critical to always assess the magnetic strength of the anchor magnets: the thickness of the steel plate, coatings or paints and uneven surfaces can influence the magnetic force. McNetiq’s patented Controlock® system allows the users to check this strength on the spot.

McNetiq’s Controlock systems are in use since 2014, especially when connecting scaffoldings to storage tanks. Users include a large range of the most reputable global independent tank storage operators, mayor oil producers, and chemical producers.

Examples of use

Ship construction and repair

For the safe installation of handrails or execution of tasks.

Construction cranes, harbor cranes and loading/unloading bridge cranes

For the safe executing of inspections or repairs.


For the safe stowage or inspection on top of containers.

In vessel holds

During the inspection, repair or cleaning of vessel holds.


For use during the construction, maintenance & repair operations and decommissioning of offshore installations.


How to use a magnetic anchor?

Based on an earlier defined plan for safe installation of the fall restraints, two or more McNetiq Controlock anchors will be installed. Steel or nylon ropes will be connected to the anchor magnets, depending on if there is a fire hazardous operation like welding or grinding. A running leash with safety harness will be attached. One of the team members will be a trained as certified Controlock operator, who will test the McNetiq Controlock anchor on its magnetic strength (pull and shear) with a handheld testing device. After confirming the correct force being exceeded, the use of the anchor will be cleared, and the safety harness will be connected.
