Ventilation Hygiene Requirements

Ventilation systems are designed to go un-noticed but provide a building with clean fresh air, creating the right temperature and air quality to achieve the right atmosphere for the purpose of a building. When ventilation systems become neglected or breakdown the required atmosphere can change drastically, air can become damp, décor can start to deteriorate, unfiltered air can contaminate a building leading to ill health of the persons occupying it and finally the risk of fire is increased due to the build up dry flammable materials within the system. A system which isn’t running efficiently will financially cost a company as energy costs are on the incline. A simple inspection can be carried out, which will identify the condition of the systems, any repair or cleaning works required, a breakdown of costs for the works and how often we recommend the system is inspected.

Most ventilation systems are located above ceilings in roof voids, so knowing the condition of the system without a proper professional survey is virtually impossible. If there are signs of debris or discolorations around the face of a grille or louvre it is pretty much safe to say there will be some form of contamination within the ductwork systems.

Surveying & Analytical works

To determine the condition of any ventilation system it is advised a trained engineer visit site to carry out a detailed survey. The survey will cover all aspect of the ventilation system and provide the customer with non bias informative report showing all findings. This information is always backed up with visual images.

No matter the size or complexity of the works we would always carry out a pre work survey to ensure the safety of the building occupancy and the safety of the operatives carrying out the works.

Where required we have trained operatives who carry out analytical sampling works to determine the contamination levels within a system, and then identify the most effective methods of removing the debris. On completion of the cleaning works we would also carry out analytical sampling works to prove the system is cleaned to the recommended standard.

If a system does not require cleaning, we will detail this within our report which will be supported with relevant test results. (insurance companies will take this information into consideration when assessing a building)

Cleaning Methods

Should a system require cleaning we would organise a site meeting with the customer with our prepared method & risk assessment detailing the works required and how we propose to implement these works. All works we carry out will conform to current standards and specifications detailed by H.V.C.A “Guide to Good Practice”

INTERNAL CLEANLINESS OF VENTILATION SYSTEMS TR / 19

All ductwork ventilation systems vary in size, shape and complexity. We are capable of cleaning all ductwork systems to the required standards using approved methods to achieve the level of clean required. The works will also be supported by verification testing.

Verification & Test Results

All works are supported by a completion report complete with test results – photographic / video images – conformance certification and recommendations.
