Air quality in working environment and inside air
Use air quality measurements to document compliance with occupational limit values.
Air quality matters to our health and well-being
The quality of the air we breathe is highly significant when it comes to our well-being and health. Air quality is affected by a variety of factors when we are inside or at work.
Measurements are used to document the quality of workplace air and show whether measures must be taken to comply with the occupational limit values.
FORCE Technology can assist with air quality measurements and advice on how to improve the air quality.
Particles and gases in working environments and indoor
Working environments may be negatively impacted by air pollution from manufacturing processes or nearby sources. This can affect employees' health, efficiency, and attitudes toward work, in both production and office environments. To ensure a good indoor climate and working environment for employees that may be exposed to pollutants, measuring relevant chemical contaminants is a critical first step.
If you want to assess whether values in your workplace are within the limits set by the relevant working environment authorities, it is necessary to measure and examine gases and particles. For substances where there are no existing limit values, the results of the measurements should be assessed based on knowledge of the health impact of the substances in question.
Results from measurements often used in decision-making for initiatives to improve air quality in the working environment, as well as to assess the effect of such measures. You can also use the measurement results for a risk assessment of individual work processes.
FORCE Technology offers consultancy on measures to improve the air quality in working environments, and performs:
- Measurements of air pollution in working environments, including respirable dust, total dust, ultrafine particles, and all types of inorganic and organic gases.
- Evaluation of possible health hazards for substances without existing limit values.
- Measurements of indoor air quality, including monitoring ventilation needs in office environments, as well as any intrusion or evaporation of gases to the indoor climate.
Accredited measurement of dust and gases in working environments
We perform measurements in working environments in accordance with applicable national and international standards, and we have a comprehensive range of instrumentation at our disposal. This ensures that the measurement results can be used as documentation to the relevant Working Environment Authority. We have an extensive suite of instruments carrying out measurements in the working environment and we can perform measurement of virtually all chemical substances in gaseous or particulate form.
Measurements can be taken using stationary or mobile equipment, over a long or short period of time, depending on your needs and the purpose for the measurements.
Based on the results obtained, FORCE Technology can advise you on how to comply with requirements and on initiatives you can implement to improve the air quality.
Chemical risk assessment
When employees work with or are exposed to chemical substances, a chemical risk assessment should be performed. If the written risk assessment does not provide a clear answer to the exposure (degree, type, duration and quantity), you can supplement it with measurements that you can use as documentation in the chemical risk assessment.

FAQ - air quality in working environments
When should you measure substances in the working environment?
You must make measurements if you want to know how exposed the employees are to chemical substances in certain work situations, or if there is doubt about compliance with limit values for a given substance.
Measurements can also be made if there are changes in working conditions or work processes that can change the exposure to chemical substances.
What is the best way to measure gases and particles in the work environment?
Person-based measurement is preferable when assessing the exposure risk of a specific work process. A small, belt-mounted pump collects the substances. Subsequently, the sample is analyzed and the measured concentration can now be calculated. You can compare with the result from a stationary measurement to include worst case exposures in the assessment.
With continuous measurement, you can follow the concentrations around a process both over time and place, however, they are difficult to use for personal measurements.
How many work environment measurements must be made to assess whether the air quality in the work environment is OK?
This depends entirely on whether these are orientation measurements or documentation measurements.
Orientation measurements are carried out by the company on its own initiative to clarify whether there is reason to take improvement measures such as increased ventilation, structural changes, or reorganize the work. There are no formal requirements for the number of measurements.
Always take measurements under "realistic worst case conditions" to avoid doubt scenarios. Typically, you must perform at least one “realistic worst case” measurement for each relevant process type. If many people work in the same room, we recommend performing a reference measurement in the room, at a good distance from the process in question, to assess the general exposure in the room.
Orientation measurements can be performed either as person-borne measurements or as stationary measurements.
Documentation measurements are performed as documentation to the Danish Working Environment Authority and must be performed in accordance with the standard DS / EN 689: 2018 + AC: 2019. The number of measurements depends on how close the measured concentration level is to the current limit value. Plan documentation measurements carefully so that you avoid having to perform additional measurements. Person-borne measurements should be included as far as possible in documentation measurements.
How long does a work environment measurement take?
This depends on the lowest analytical detection limit of the measured compound. Normally, the required sample can be collected in less than three hours. For hexavalent chromium (Cr (VI)), the minimum sampling time is about 105 minutes.
What if there is no limit value for the substance you are working with?
Not all chemical substances are subject to limit values. However, you can still make an assessment of whether the measured concentration poses a risk to health. You do this by making a hazard assessment of the individual substance and holding it up against the measured concentration.
Regardless of whether there is a limit value for a substance or not, the work must be planned, organized and carried out so that it is fully justifiable in terms of safety and health (according to the Danish Working Environment Authority's requirements for work with substances and materials). Fx. you need to avoid unnecessary exposure to substances and reduce it as much as is technically reasonable.
When should work environment measurements be performed accredited?
Documentation measurements must be performed accredited when the measurement is required in an injunction from the Danish Working Environment Authority. The measurement must be performed according to the standard DS / EN 689: 2018 + AC: 2019. The number of measurements depends on how close the measured concentration level is to the current limit value.
Therefore, it is important to plan documentation measurements carefully so that you avoid having to perform additional measurements. Person-borne measurements should be included as far as possible in documentation measurements.
What is the difference between occupational health and safety measurements and occupational hygiene measurements?
Occupational hygiene measurements include both biological measurements and air pollution measurements.
Working environment measurements are normally used only as a designation for air pollution measurements.
