Ventilation Ductwork Cleaning and Maintenance

Ensure your Ventilation System Cleaning is Compliant

The Importance of Ventilation Ductwork Cleaning

Dirt, dust, and debris are no strangers to industrial Heating, Ventilation and Air Conditioning (HVAC) systems – without any ductwork cleaning they build up in those systems and interfere not only with the efficiency and workload of the HVAC system, but also impacts the indoor air quality. This can be both costly to the plantand associated HVAC system as well as the business and individual.

The ventilation system can be home to:
– Particulates – Mixture of solids drifting in the air, consisting of dust, dander (skin flakes), soot, pollen and smoke particles.
– Microbes – Bacteria, viruses, fungi, spores and mold.
– Gases/Odours – Indoor gases release from furniture, carpets, cleaning chemicals, insulation etc.

Poor air quality can cause a reduction in productivity and a rise in absenteeism resulting in a cost to the business in poor productivity and lost days at work.

Sick Building Syndrome (SBS)

Sick Building Syndrome (SBS) is a condition in which people in the building suffer from symptoms resulting physical or environmental factors such as ventilation, workplace layout etc. 

Common Symptoms

  • headaches
  • blocked or runny nose
  • dry, itchy skin
  • dry, sore eyes or throat
  • cough or wheezing
  • rashes
  • tiredness and difficulty concentrating

The best way to combat the effects of these foreign materials and particulates is to invest in professional and thorough HVAC systems Ventilation Ductwork cleaning from Hydro-X Air.

Legislation – Health and Safety Law

The Management of Health & Safety at Work Regulations 1999 impose a duty on every employer to make a suitable and sufficient assessment of:

  1. the risks to the health and safety of his employees to which they are exposed whilst they are at work, and
  2. the risks to the health and safety of persons not in his employment arising out of or in connection with the conduct by him of his undertaking.

Regulation 5 of the Workplace (Health, Safety and Welfare) Regulations 1992 imposes a duty to clean mechanical ventilation systems “as appropriate”. Regulation 6 states, “effective and suitable provision shall be made to ensure that every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air”.

ACOP6 (52) relating to Regulation 6 of the Workplace (Health, Safety and Welfare) Regulations, 1992 states that “mechanical ventilation systems (including air conditioning systems) should be regularly and properly cleaned, tested and maintained to ensure that they are kept clean and free from anything which may contaminate the air”.

British Standard BS EN 15780 provides benchmarks to define cleanliness and dirtiness.

HTM 03-01 – Healthcare providers have a duty of care to ensure that appropriate governance arrangements are in place and are managed effectively. The Health Technical Memorandum series provides best practice engineering standards and policy to enable management of this duty of care. HTM 03-01 specifically provides guidance on the legal requirements, design implications, maintenance and operation of specialised ventilation in healthcare premises providing acute care.
