Analysis and Evaluation of Working Conditions

In the gradar algorithm for the evaluation of working conditions, a stress level is selected for each factor and provided with a time portion of the stress.

Time shares of the burden / exposure

  1. No relevant duration of exposure
  2. The duration of the burden is usually up to 10% of the working time.
  3. The duration of the burden is usually up to 25% of the working time
  4. The duration of the burden is usually up to 50% of the working time
  5. The duration of the burden is usually up to 75% of the working time
  6. The duration of the burden extends throughout the entire working time

Psychological stress

  1. No significant burden

  2. Low stress due to conflicts / confrontations or interruptions of concentration / demands on attention

  3. Average stress due to conflicts / confrontations or interruptions of concentration / demands on attention

  4. High stress due to conflicts / confrontations or interruptions of concentration

  5. Significant burden of conflicts / confrontations or interruptions of concentration

Static physical efforts

  1. No significant effort

  2. Low static stress on muscles

  3. Average static stress on muscles

  4. High static stress on muscles

  5. Considerable static load on the musculature

Dynamic physical efforts

  1. No significant effort

  2. Low dynamic stress on muscles

  3. Average dynamic stress on muscles

  4. High dynamic stress on muscles

  5. Considerable dynamic strain on the muscles

Unilateral physical strain / forced posture

  1. No significant strain

  2. Low stress due to forced postures

  3. Average stress due to forced postures

  4. High stress due to forced postures

  5. Considerable burden due to forced postures

Skill requirements (fine motor skills / dexterity)

  1. No significant requirement

  2. Low demands on fine motor skills or body dexterity

  3. Average requirements for fine motor skills or body dexterity

  4. High demands on fine motor skills or body dexterity

  5. Highest demands on fine motor skills or body dexterity

External influences: Heat, dirt, dust, cold (mechanical / physical)

  1. No significant burden

  2. Low burden, no protective clothing or special equipment required

  3. Medium burden, some protective clothing required

  4. High burden: full protective clothing or special equipment is required

  5. Extreme burden: massive full protection is necessary for life support

External influences: Nuclear, biological, chemical (NBC)

  1. No significant burden

  2. Low burden, no protective clothing or special equipment required

  3. Medium burden, some protective clothing required

  4. High burden: full protective clothing or special equipment is required

  5. Extreme burden: massive full protection is necessary for life support
