For classification in activities with and without safety level classification
When working with biological agents, a differentiation is made between activities with and without safety level classification. This is because of different approaches with the risk assessment.
All activities involving the use of biological agents in laboratories, with laboratory animals, in the area of biotechnology and in healthcare facilities have to be assigned to a safety level. They are therefore called safety level activities. With safety level activities, the biological agents which arise or are used are generally known or can at least be sufficiently determined. A differentiation is made between targeted and non-targeted activities.
In the case of targeted activities, the safety level depends on the risk group of the biological agent to be determined. If employees carry out activities with several biological agents, the safety level classification depends on the biological agent with the highest risk group. In the case of non-targeted activities, the safety level classification depends on the risk group of the biological agent which, on the basis of
determines the risk of infection of the employees.
Activities which do not take place in laboratories, with laboratory animals, in the area of biotechnology or in healthcare facilities are not allocated to a safety level. They are therefore called non-safety level activities. These include, for example, cleaning and refurbishment work, activities in the area of veterinary medicine, in agriculture, forest, waste water, and general waste management, and in biogas plants and abattoirs.
With non-safety level activities, obtaining all of the information for the risk assessment is frequently difficult. This is because both the range of biological agents is subject to variations and because the type, duration level or frequency of the exposure can change. The following can be helpful:
