Title Accident caused by cleaning operations in an underground car park
Original title Massenunfall bei Reinigungsarbeiten in einer Tiefgarage [in German]
Bibliographic information 2000, No.2, p.6-8. Illus.
Abstract All four workers performing cleaning work in an underground car park with a high-pressure jet-cleaner with oil-fired heater had to be treated for carbon monoxide poisoning. The exhaust gases from the oil-fired heater had increased the carbon monoxide concentration in the underground car park to 500mL/m3. This level was roughly 16 times higher than the German exposure limit of 30mL/m3. Current German regulations require the employer to take precautionary measures during such cleaning work to make sure the limit is not exceeded. A high-pressure jet cleaner with an electric heater is to be used where possible. Otherwise, the employer has to inform the workers of the hazards to ensure that the area where the cleaning operations are performed is properly ventilated and that the equipment is in good operating condition.
