Abstract:

Recent studies with numerical models regarding edge protection systems (EPS), class C according to standard EN 13374, showed that some requirements are inadequate for human safety. This problem mainly arises when a person is injured by falling directly against the EPS supports.

To analyse this subject, three series of numerical models, in accordance with EN 13374, have been produced. The paper describes these studies, which have been carried out using straight supports, different weight ballasts and also a deformable ballast.

In the first series, impacts against straight supports have been analyzed and a standard EN 13374 ballast has been used. These first studies showed too many high impact factors on the ballast. The obtained values are absolutely inadequate and dangerous to the integrity of the human body. The second series was conducted to know how different weights and shapes of ballast affect the maximum accelerations suffered by the human body. Finally, in the third series, a more deformable ballast has been used to simulate impacts of workers against straight supports, nearest to the real behaviour of a human body.

Results confirm and measure an excessive impact factor suffered by the falling person. Mainly in the first series, with direct impacts of standard ballast against straight supports, acceleration values have been generated that could seriously injure the body or even could kill workers.

The second series showed that different weights and shapes – cylinder or sphere – of ballast affect the acceleration values calculated.

Finally, in the third series, the deformable ballast has achieved results truer than previous studies with the more rigid ballast established by EN 13374.
