Air Hygiene

Current Health and Safety Legislation

Employers have a duty of care to ensure that employees and visitors to thier premises operate in a safe environment. European and UK leislation exists to protect workers and ensure acceptable levels of air and water hygiene. The European Communities Workplace Directive is implimented in the UK by the workplace HEALTH, SAFETY and WELFARE REGULATIONS 1992.

The Health and Safety Commissons Approved code of practice and guidance L24, HMSO 1992, states that “mechanical ventilation systems, including air conditioning systems, should be regularly cleaned, tested and maintained to ensure thaey are kept clean and free from anything which may contaminate the air.”

This act applies to new buildings from the publication date 1992, and applies to older buildings from 1st January 1996. Therefore, all systems should have had Risk Assessment Surveys carried out prior to this date.

Mechanical cleaning

MSM believe that the only way to achieve a quality result from cleaning is to utilise a combination of methods, air blast, rotary brush, vacuum, scrape, etc. As in many cases use of only one method is insufficient to meet the standards as required by regulations.

Part of the works will be (where applicable) to fit access panels which conform to regulations at the correct intervals, dependent on ductwork size.

During the cleaning process any minor corrosion is treated accordingly and major problems reported to the client. During the works protective sheeting and powerful extraction is employed to prevent the spread of dust and debris

All debris will be removed from site in sealed containers and upon completion the Cleanliness Certificate is issued for you to display.
