What do I have to do when there are no specific provisions for the determined hazards?

If you researched the relevant legal references and evaluation aids for all hazard factors and there still are no specific provisions for the determined hazards (as described in step 2), you must evaluate and assess the remaining risks yourself. Determine the possible severity of a risk of accidents or an impairment of health and the likelihood of it occurring. The goal is to reduce the risk to an acceptable extent.

Risk estimation

Within the framework of risk estimation,

  • the extent of the possible damage that may be caused by the hazard being considered and
  • the likelihood of this damage occurring

are estimated.

Risk estimation

Within the framework of risk evaluation, it is determined whether the risk is lower than the highest acceptable risk. If the result of the risk evaluation is that the existing risk is unacceptable, the risk must be reduced.

In the literature you will find different methods you may use in order to assess hazards. Examples include the method according to Nohl (“Risk matrix”) 1) or the decision tree pursuant to DIN EN ISO 13 849-1.

Tip: The research report of the BAuA F2216 "Risikobeurteilung im Maschinenbau" (risk assessment in mechanical engineering) provides an overview of methods for the risk assessment of machines and is intended to support manufacturers, specifically designers, in implementing the risk assessment required pursuant to the European Machine Directive 2006/42/EC. Based on the representation of the basic approach when assessing a risk and the explanation of essential terms, possible methods and guidelines referring to the individual steps of the risk assessment are presented.
