Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with smoke and ideally adding a small amount of pressure to the area being tested, will result in a visible discharge of smoke and, simply put, the greater the volume of smoke, the bigger the leak. After Concept developed a bespoke system for their aircraft testing requirements, a spokesperson for the RAF commented: `The use of smoke as a means by which to detect cabin pressurisation leaks has been shown to be extremely effective and is unquestionably superior to any alternative detection method used to date!`
Concept smoke systems are used throughout the world for testing smoke detectors of all types. And by smoke detector manufacturers in their own testing facilities. Concept also supply specialist equipment for testing smoke detectors in commercial aircraft, with users including Boeing, Meggitt, Alcoa, Apache, Dassault Falcon and IAI.
For many years, materials containing isocyanate have been the single biggest cause of occupational asthma in the UK. Vehicle paint sprayers are 80 times more likely to develop occupational asthma than workers in other industries. This is caused by the inhalation of the fine paint mist that is generated when paint spraying. There is a requirement for the measurement and display of `clearance times` for spray booths / rooms set by the HSE and the Motor Vehicle Repair (MVR) to meet the requirements of Control of Substances Hazardous to Health (COSHH).
When water-based artificial smoke is introduced into a rapidly moving air stream, the particles that make up the artificial smoke evaporate much more quickly than they do in a static environment. So if you are looking to produce an artificial smoke that better represents the smoke created by a real fire, we would always recommend the ViCount smoke generator, the smoke from which is virtually unaffected by fast moving air streams. Used world wide PPV training centre`s and to test impulse ventilation systems. A Home Office report into PPV (Positive pressure Ventilation) by the Head of the Fire Experimental Unit, Fire Research & Development concluded that the concept behind the technique of PPV was relatively easy to understand and the equipment simple to operate, but stressed the need for extensive training.
Making smoke in a very open environment or external environment can be a challenging! An oil-based smoke generator, such as a ViCount system, can produce dramatically more artificial smoke than multiple water based systems. This is due to the fact that the smoke ViCounts produce, being oil-based, does not evaporate in the same way and speed that water-based smoke does. The smoke from a ViCount smoke generator will travel for 1000`s of meters, compared to a typical water based smoke machine that may produce a smoke visible for 100 meters. Just one ViCount or Vulcan can replace 10 or more conventional water based smoke systems. ViCount`s have been used world wide for many tunnel smoke simulations, be it for RTA training / evacuation exercises or tunnel ventilation testing.
