In this article we briefly explain how a correct design of any machine should be to minimize possible accidents.

In many cases, the analysis of accidents caused by machines use can reveal manufacturing defects, misuse, faults, malfunctions… This analysis will reveal that with a design in which safety is considered as a whole, the possibility of an accident occurring is reduced.

When a corrective action to eliminate an aspect or situation that generates risk in a machine must be taken, it may happen that the solution behind it has a complicated implementation, the correct way to deal with these cases is, when considering the design of a machine, to take into account all the situations that may occur, thus saving time in correcting faults after use, avoiding problems and reducing the risk of accidents

Concerning machine safety, all aspect of the machines’ life should be considered, not only in their manufacture and shipment to the customer, but also throughout their useful life with the customer; maintenance tasks, scrapping once their use has ended, etc. All these risks are covered by a risk assessment that identifies all hazards existing and/or generated by the machine during all phases of its service life.

Late-detected risks or occurred accidents should be included and evaluated when making future evaluations, especially during the design phase. That is why in the early phases of a machine project it is necessary to focus on security towards the construction of a 100% safe machine.
