Environmental Hygiene Management Programme

Background:

Specific hygiene issues regarding air quality were brought to the attention of System Hygienics by a leading pharmaceutical company.

‘Fresh’ air is supplied to their office and manufacturing areas via mechanical ventilation systems, similarly forced ventilation systems are also used in the pharmaceutical manufacturing process.

Therefore high standards of air quality are essential.

Solution:

System Hygienics working closely with the client implemented an Environmental Hygiene Management Programme so that the room ventilation systems and the pharmaceutical manufacturing systems, including the local exhaust ventilation systems (LEV’s), received regular ‘health’ checks.

The programme included cleaning specific areas and components of the ventilation systems, primarily: - The fresh air intake ductwork and the heating and cooling coils, including condensate drain trays. Following hygiene maintenance ‘wet’ areas such as the cooling coils, condensate drain trays and humidifiers were disinfected with a low-toxicity biocide, which included the flushing of the condensate exterior drain lines to ensure efficient drainage.

The AHU’s and other components of the ventilation systems were inspected with a view to their material and hygiene conditions. Tests were taken from the ventilation systems interior surfaces to establish dust/contaminant build up and microbiological samples taken to determine bacterial and fungal colonization.


Results:
The Environmental Hygiene Management Programme (EHMP) ensures that the served environments and the pharmaceutical manufacturing systems are supplied with high standards of ‘Fresh’ air.

Following the EHMP System Hygienics provides a concise report complete with photographs and an assessment of test and sampling results, including any recommendations for remedial works, where applicable. These scheduled ‘Health’ Checks: -

  • Comply with Workplace Regulations (1992) Approved Code of Practice, which states that: - “Mechanical ventilation systems, including air conditioning systems, should be regularly and properly inspected, tested and maintained to ensure that they are clean and free from any thing which may contaminate the air”.
