Indoor air - Ingressi
Good indoor air at the workplace affects the healthiness of the work environment, the atmosphere and functionality of the work community, and the productivity. The employer must ensure that indoor climate conditions are healthy and safe.
Indoor air - Yleistä
Poor indoor air quality is known to cause, for example,
- respiratory tract Infections
- nasal congestion or discharge
- itching, burning or irritation of the eyes
- throat hoarseness or dryness
- general fatigue and headaches, and
- on rare occasions, fever and muscle and joint pain.
If there is an indoor climate issue, symptoms typically occur inside the building. Usually the symptoms ease once the affected person has left the building.
If workers are found to be suffering from an indoor climate issue at the workplace, the employer must take any necessary steps to prevent exposure and eliminate the causes.
Many factors can cause an indoor climate issue
The following factors can contribute to poor indoor air quality (the list is not exhaustive):
- ineffective or insufficient ventilation (correct capacity for the number of persons)
- release of mould spores from damp structures
- flooring materials’ reactions to moisture
- volatile unhealthy emissions from construction and interior decoration materials and furniture
- mineral wool fibres released from uncoated ventilation duct dampers and soundproofing boards
- temperature conditions and draughtiness that have negative impact on well-being
- items that do not belong to the workspaces
- incorrect cleaning methods or inadequate cleaning.
Indoor air quality issues must be tackled methodically
There must be agreed procedures in place to tackle indoor climate issues, and based on these procedures the employer
- informs personnel about poor indoor climate at the workplace
- setting up a working group on indoor air quality, if necessary
- consulting occupational health care professionals
- uses experts on indoor climate to review the condition of the building and to assess the results
- disseminating information openly and promptly
- drawing up a plan and a schedule of corrective actions and implementing the same
- monitoring the impact of the actions taken on workers’ health.

Let your employer and occupational safety and health representative know if you suspect that there is a problem related to indoor climate at your workplace. Your employer has a duty to keep both you and the occupational safety and health representative up to date on any actions that have been or will be taken to address the issue. Your employer must also let you know if they deem it unnecessary to take any action.
You should let your employer and occupational safety and health representative know if you notice any symptoms that you believe could be due to poor indoor air quality at your workplace. The employer must determine together with occupational healthcare whether your symptoms are caused by the conditions at the workplace. You should also talk to your employer’s occupational health care provider about any symptoms. Occupational health care professionals can propose changes to allow you to continue working in the space that is causing you symptoms.
If your symptoms are found to be caused by poor indoor air quality at your workplace, your employer must take steps to find out the cause of the issue and eliminate it. Your employer is also responsible for ensuring that your health is not put at risk while the investigation is carried out and the remedial action implemented.
It takes time to carry out a thorough investigation, draw up a report and a plan of corrective actions, and to implement the plan. You can ask your line manager or occupational safety and health representative for updates on the situation and when solutions are expected.
The occupational safety and health authority supervises
If your employer does not take appropriate measures to examine the cause for poor indoor air quality and to prevent exposure, you can call the occupational safety and health authority’s national helpline for advice and information.

Health risks caused by indoor climate must be prevented
Good planning and construction prevent indoor climate issues. This means, for example, that emission-free building and interior decoration materials are selected and that proper and functional ventilation is provided. Additional attention should be paid to
- efficient engineering solutions, such as drainage
- functional and clean ventilation system
- regular maintenance of the building
Any leaks must be addressed immediately and the affected structures dried in order to prevent microbial growth. As a rule, any damaged materials should be removed. The cause must be investigated and repairs carried out to prevent any recurrence of the problem.
In the event that the building is leased, the employer must contact the landlord to agree on repairs and maintenance. The employer is always ultimately responsible for their workers’ health. The employer can terminate the lease agreement if the conditions in the building are obviously putting workers’ health at risk.
Health hazards must be eliminated without delay and the impacts of the remedial action monitored
It is the employer’s duty to ensure that there are procedures in place to prevent any harmful effects on health resulting from poor indoor climate and to address any issues.
Procedure for addressing indoor air quality issues in the workplace
It is the employer’s duty to
- consult with their occupational health care provider or other health care specialists to establish whether any symptoms of workers are due to their work
- determine in cooperation with their occupational health care provider which workers could potentially continue to
- determine the condition of the building reliably and thoroughly and assess its impact on the indoor climate (indoor climate review); if the employer does not have required expertise, an expert should be used for the indoor climate review
- carefully plan for repairs and implement them so that the repair work does not negatively affect the construction workers or others in the vicinity
- work in the affected building without risking their health and on which conditions
- carry out the repairs as planned
- ensure that the facilities are properly and sufficiently cleaned after the repairs
- monitor in close cooperation with their occupational healthcare provider or other healthcare professionals the adequacy of any action taken and its effect on employees’ health.
Employers can prevent rumours by communicating openly about any investigations into indoor climate issues and the progress of remedial action. If there is insufficient communication about investigating the indoor climate issue, the employees might get an impression that the employer does not take employees’ symptoms seriously.
Setting up a working group on indoor air quality is often a good idea. In most cases, these kinds of working groups consist of line managers, representatives of the property owner and the maintenance company, the employer’s occupational safety and health manager and the occupational safety and health representative, occupational health care professionals and a representative of the affected workers. External specialists can also be invited to the working group’s meetings.
Open and timely communication is crucial
Employers can prevent rumours by communicating openly about any investigations into indoor climate issues and the progress of remedial action. If information about how indoor air quality issues are being dealt with is withheld, workers may think that their employer is not taking their symptoms seriously even if the employer has in fact taken steps to address the issue.
When investigating an indoor climate issue at the workplace, it is important to remember that details about individual employees’ health constitute classified information legislation enforced by the health protection authority on indoor climate issues. Information about individual workers’ health cannot be shared with other workers. Only health care professionals can determine whether workers’ symptoms are caused by something in their workplace.
In order to keep workers properly informed about the progress of steps taken to address indoor climate issues, employers should give them regular updates on
- what is known
- what is not known
- what will be done to remedy the situation
- when will remedial action be taken
- what will happen next, and
- how the impact of remedial action will be monitored.
