Frequently asked questions
Below you will find answers to some of the most common questions which we receive from customers.
If you have other questions, please do not hesitate to contact us.
Yes! We have our channel duct system, made for moving vehicles, or moving work areas.
We also have our PRS and MRS(G) systems, made for emergency vehicles start up inside the garage and drive out.
We have made a line specifically for emergency vehicles where the extraction nozzle disconnects automatically and moves out of the way as the vehicle exits the garage.
Vehicle exhaust fumes can irritate the eyes and respiratory tract, and are a risk to health by breathing in. Carbon-fuelled engine fumes contain carbon monoxide, a poisonous gas. Prolonged exposure to diesel fumes, especially blue or black smoke, may lead to coughing and breathlessness. Long-term repeated exposure to diesel fumes over a period of about 20 years may increase the risk of lung cancer.
Exhaust fumes can quickly reach harmful concentrations, particularly from cold or intermittently run engines (when run indoors without exhaust ventilation). Don’t rely on catalytic converters to run engines safely indoors. They are less effective when exhaust gases are relatively cool, eg from vehicles idling for long periods or used intermittently for short periods. Catalytic converters do not remove toxic oxides of nitrogen.
Keep the workplace well ventilated. Connect an exhaust gas extraction system to the vehicle tailpipe when idling, particularly when working in a vehicle inspection pit. It should ventilate to a safe place in the open air – where fume will not be drawn back into the workshop or affect other premises or people nearby. Maintain couplings and flexible connections in good condition to prevent leaks. You should not rely on vehicle access doors being left open to provide ventilation as in winter these will be kept closed.
