Work at height requirements and regulations

VERTIC Safety at height

You work at height and you still have some doubts in how to use of fall protection equipments? You need advice regarding P.P.E. and permanent fall protection solutions according to your needs and requirements?


DELTA PLUS SYSTEMS gives you the appropriate support to ensure maximum safety at height for you and your team.

Choosing the proper fall protection solution requires expertise and also to consider many factors and concepts. Let’s follow the guide!



New European P.P.E. Regulation 2016/45


To ensure workers a protection even more effective, the Directive 89/686 has been replaced by the European P.P.E. Regulation 2016/425. In force since the 21st April, it has been giving more guarantees to users by giving more responsibility to manufacturers, distributors, importers, notified bodies and authorities.


To know more about the Regulation 2016/425, please have a look on the file below from our group DELTA PLUS. Do not hesitate to contact us if you have any questions.


What is fall factor?


The fall factor represents the proportional degree of severity of a fall. Its value lies between 0 and 2 and can be calculated by dividing the fall height by the rope/lanyard lenght. Above a fall factor of 0.3, there is a danger.


To limit fall factor, two solutions:

  • Raising the anchor point position
  • Increasing the braking distance to reduce the force of the fall impact.

Factor 0: limited free fall

The anchor point is above the user’s head and the lanyard is tightened.


Factor 1 : Free fall up to one time lanyard/rope system lenght

The anchor point is at the same level than the user’s chest, i.e. at the sternal attachment point.


Factor 2 : Free fall up to two times lanyard/rope system lenght

The anchor point is at the same level than the user’s feet, i.e. between the sternal attachment point and the ground.


What is fall clearance?


Fall clearance is the distance between the anchor point and the ground. Two different notions of fall clearance must be distinguished: the Fall Clearance Available (F.C.A.) and the Minimum Required Clearance (M.R.C.).


The F.C.A.: represents the distance between the structure on which the user works and the nearest obstacle (ground, wall,…).


The M.R.C.: represents the minimum required distance, so that the user falls without any risk of collision with the nearest obstacle. It is calculated as follows:


Lanyard lenght
+ extension of the energy absorber
+ user’s size
+ minimum safety distance (1m)

What is swinging effect?


The swinging effect or pendulum effect represents the risk of swing like a pendulum if a fall occur, and in the case that the P.P.E. worn, is not directly anchored overhead. During the swing and the fall you may strike the structure you are working on or another nearby obstacle (wall, ground,…).


To limit the swinging effect, you need to keep an angle of less than 30° between the P.P.E. and the anchor point.
