Errors in the safety fence selection – we give advice
At this point, we would like to draw your attention to the most important sources of error that can be made when selecting the protective device
In DIN EN ISO 13857 (paragraph 4.2.2) it is fixed and filed for information purposes: the user should always think generously and never dimension the safety fence too small in height. The safety of the machine must also be ensured in all cases, for example, if the operator can engage from outside via the fence to actuate the escape release to gain access.
In this way, all safety-related shutdowns would stop the machine, but any processes would continue for a few seconds (spindles, etc.), thus posing a threat to the intruder.
Insufficient safety distance to the machine
The safety distance between the housing elements and the machine is often too low. These are also mentioned in DIN EN ISO 13857 (para. 18.104.22.168).
No or inadequate protection against crawling under or overstepping
The creep height must not be oversized. It must always be ensured that no one can enter the area surrounded by the security fence by force! Recommendations are made in the new EN ISO 14120 (para. 5.18). Likewise, there are also indications, for avoiding for example, of horizontal rods, which could be used as climbing aid on the protective fence
Risk of injury by the protective fence itself
It would be undesirable, of course, if the protective fence itself could become a trap for the operator. Therefore, only standard compliant protective devices should be used. Only these are also suitable for industrial use. No matter whether you are dealing with uncleaned bars, missing protective caps on posts or other injury risks such as sharp edges. The fences we offer are standard compliant. With the right choice of the safety fence system and right-sizing, you are always well adviced to buy at our company.
