In general it may be said that measurements are provided for in the labour protection provisions if

1. Such measurements are feasible from the perspective of measuring technology (air humidity can, but stress cannot be measured).
2. Limit or reference values are available (i.e. 85 dB(A) noise exposure level).
3. Measurements permit a fairly objective evaluation of a (potential) danger, i.e. the impact on the human organism can be assessed.

Important provisions relating to measuring in labour protection are

• the measurement of work substances,
• the measurement of work noise,
• the measurement of climate parameters, such as air temperature, air velocity and air humidity,
• Measuring the intensity of lighting and luminance,
• Measuring the effectiveness of extraction systems,
• Measurement of air prior to the use of respirators

• Measurement of Noise
• Measurements (for Explosion Protection)
