In many circumstances, dust is more than an irritation – it is an outright hazard that has been linked to a wide range of long-term health problems, including lung cancer and debilitating respiratory illnesses. Dust suppression is important to mitigate some of the effects.
Dust is not a substance in itself, but a convenient catchall term for any small, airborne particle. In the home, dust is a cocktail of dead skin particles, carpet fibres, food crumbs, pollen, pet hair and other substances. On a construction site, airborne dust may contain concrete, brick, and sand particles, pulverised stone, wood chippings, micro plastics, lead and other metals – not something that anyone would want to breathe in consciously.
Some types of dust are particularly harmful. Asbestos, for instance – a naturally occurring silicate fibre that was used in construction materials for decades – is linked to various cancers, as well as the fatal lung disease Asbestos's. Other types of silica dust particle, although less notorious, are almost as harmful. The Health and Safety Executive (HSE) estimates that over 500 people die each year from the inhalation of silica dust on construction sites, which is the main reason that sandblasting is no longer legal in the UK.
Almost all activities have the potential to create dust, from the simple act of driving a construction vehicle along a trackway, to large-scale gravel quarry. Some applications, however, are singled out by the HSE as major causes of dust, in quantities likely to cause a hazard to human health.
Repeated exposure to construction and industrial dust, without the appropriate respiratory protective equipment and dust suppression equipment cause a range of debilitating and fatal conditions:
Worryingly, the daily volumes of dust that need to be inhaled to place people at risk of these conditions are tiny, often no more than a pinch of salt. This makes it essential to put effective dust suppression systems in place in environments that produce large quantities of dust.
Construction and workplace dust affects productivity as well as health. Large volumes of dust obscure visibility, reducing people’s work rate and increasing the risk of accidents. Abrasive dust particles can also interfere with construction plant and vehicles, shortening the life of equipment and increasing repair bills.
Our Trime Dust Suppression water-based dust control units are high-capacity, mobile devices that produce a fine water vapour capable of capturing all types of harmful construction dust. The Trime Dust Suppression control unit series are available in both lightweight and portable models, which are mounted on wheeled trolleys to allow rapid deployment anywhere on a construction site, and larger static models which are more suitable for jobs such as demolition. To operate, the unit is simply hooked up to a mains water supply, a water bowser with a built-in pressure pump, a pressurised water tank or hydraulic system, and aimed in the direction of the dust source.
