Health and Safety Executive - INDOOR AIR QUALITY.
ASHRAE Standard 62 defines acceptable indoor air quality as air in which there are no known
contaminants at harmful concentrations and where the substantial majority of people (80% or
more) do not express dissatisfaction. The definition covers occupant comfort, odours and
harmful levels of contaminants.
Examples of common contaminants include: carbon dioxide, carbon monoxide, microorganisms,viruses, allergens and suspended particulate material. These contaminants are introduced into indoor spaces by human and animal occupancy, by the release of contaminants in the space from furnishings, accessories and/or processes taking place in the space, or from the supply of contaminated fresh air.
Poor indoor air quality may be discernible by occupants as visible suspended particulate matter in the air or odours, or may be discernible only by sensitive measuring devices.
In the UK, the primary regulation governing occupational exposure to harmful substances is the Control Of Substances Hazardous to Health (COSHH) regulations.
This presents eight measures which employers or employees must take to maintain safe working practices. These include tasks such as risk assessment, control measures, monitoring and training.
Failure to comply with the COSHH regulations can result in prosecution.
Research has increased in recent years into indoor air quality, as a result of changes in building techniques in order to manage increasing energy costs and to lower ventilation rates.
We now work in many industries where indoor air quality is affected by known harmful substances and each year thousands of workers are made ill contracting lung disease such as asthma, cancer and skin disease such as dermatitis.
The most important element of indoor air quality is the cleanliness of the air.
Breathing in substances called respiratory sensitisers at work can cause occupational asthma.
A respiratory sensitiser is a substance which when breathed in can trigger an irreversible allergic reaction in the respiratory system. Once this sensitisation reaction has taken place, further exposure to the substance, even to the tiniest trace, will produce symptoms.
Sensitisation does not usually take place right away. It generally happens after several months or even years of breathing in the sensitiser.
Symptoms are - asthma - attacks of coughing,wheezing and chest tightness: rhinitis and conjunctivitis - runny or stuffy nose and watery or prickly eyes.
Continued exposure can result in permanent damage to lungs and increasingly severe symptoms and attacks often continue for years after exposure to the sensitiser has stopped.
Respiratory sensitisers are subject to the Control of Substances Hazardous to Health Regulations.
There is a huge cost to industry, society and individuals.
Filtaire Air Purifiers can play a very important role in helping with controlling airborne contaminates in terms of particulates, gases and vapours in most situations, and deliver safe, clean air with significant improvements to indoor air quality (IAQ). and a reduction in health risks to people.
Sub micron particulate filtration together with contaminate specific carbons are effective in most buildings,rooms and indoor spaces where hazardous substances are found or created as a result of a process.
Filtaire equipment provides a 'focused' treatment of the air and will assist in the application of 'Source Control' measures, identified as being very effective.
Filtaire Air Purifiers are simple to use, with a range to suit various room volumes and a choice of specialised contaminate specific activated carbon filters for an extremely wide variety of applications.
Independent test results illustrate their effectiveness for both particulate and VOC filtration.
