• WORKSHOP warm air heating units are dangerous if not installed to standards laid down by the Heating and Ventilating Contractors Association.
A heating company, Crown Heating & Ventilating Services, which has just installed its 5,000th unit, has issued a warning to garages and the transport industry generally over the danger of cheap installation.
Units can be bought off the shelf and a manager may be tempted to handle the installation himself — a highly dangerous practice. says Crown Heating's managing director, Ivor Oswin.
"Ile won't necessarily know whether his building is safe for such an installation, whether he has bought the right heater nor whether it meets the current criteria for quality standards, codes of practice and buildings regulations," says Oswin.
"If the heater is wrongly installed in an environment of petrol fumes, it could have the effect of a time bomb. The safe answer is to engage a recognised heating engineer who is a member of the Heating and Ventilating Contractors Association."

• AIR VENTED into the atmosphere from blow guns must be clean and dry, say the latest Health and Safety Executive recommendations (Compressed Air Safety, HMSO ISBN 0 11 085529 8 — £4).
"Because air is vented directly into the atmosphere, clean dry air is essential and lubricants should not be used," says the HSE.
These recommendations are published, says Ultrafilter, shortly after its own tests reveal that air from compressed air systems using the firm's oil-free pack is several times cleaner than that obtained from dry-running compressors.
Year-long tests at its West German hq, says Ultrafilter, show that, fitted with a proper purification system, oil-lubricated air compressors produce better quality air than "so-called 'oil-free' compressors".
General manager Nigel Morris says: "We are delighted to see the USE agreeing with our lung-held view that too little attention has been paid to the health of blowgun operators and other employees of companies which use such equipment."
Morris adds that dirty or wet oil can lead to corrosion and blocked valves which may make the system unsafe.
The USE recommendations also say that it is good practice to shield all non-metallic filter bowls to guard against damage and the risk of explosion during cleaning operations.
