Workplace ventilation requirements in Poland: OSH rules
Ventilation decides whether the air in a workroom is safe to breathe, and Polish OSH (occupational safety and health) law treats it as a hard requirement, not a comfort feature. Minimum temperature thresholds are a separate subject — you will find those, and the pending rules on a maximum, in Workplace temperature: office or production hall?
Protecting rooms from heat and cold
To protect yourself and your employees from cold and excessive heat, rooms and workstations must be properly safeguarded:
- against uncontrolled heat emission (e.g. from machinery or installations)
- against cold air flowing in from outside
- against draughts and sudden changes in temperature
The goal is stable working conditions that cause neither hypothermia nor overheating.
What ventilation must deliver
Ventilation is the key to a safe indoor climate at work. Its purpose is:
- removing solid and gaseous contaminants
- maintaining the right temperature and humidity
- adequate air exchange
In rooms where substances harmful to health are present, ventilation must keep concentrations below the permitted limits. Detailed air quality requirements are set out in the Polish Standards (Polskie Normy) and in separate regulations.
Where workstations are exposed to intense radiant heat, local supply ventilation must be used. Its parameters have to be matched to what is known as a hot microclimate, so that workers’ health is not put at risk.
Equipment that can release harmful gases, vapours or dusts should be fully enclosed. Where that is not possible, local exhaust ventilation must be installed to stop contaminants spreading through the room.
Air conditioning and mechanical ventilation — what to watch for
Air supplied from outside:
- must be cleaned of dust and harmful substances
- must not cause draughts, chilling or overheating of rooms
- should not be blown directly at workstations
Remember to have the ventilation and air conditioning systems inspected at regular intervals.
The regulations also cap the temperature of the air supplied:
- up to 70°C where the air inlet sits more than 3.5 m above the floor
- up to 45°C in all other cases
Additional rules apply in rooms at risk of fire or explosion.
Employer’s duties
The employer is required to:
- service the ventilation and air conditioning systems regularly
- limit the noise and vibration these systems generate
- install alarm systems where a ventilation failure could endanger workers’ health
Working ventilation, controlled air supply and properly maintained air conditioning are the foundation of a safe working environment. Complying with OSH regulations here protects employees’ health, cuts the risk of accidents and makes work more comfortable. And remember that every environment has its own requirements — confined spaces, construction sites and offices alike. Start building a safe indoor climate with EHS CONSULTING today!
