There Are Special Regulations for the Construction and Maintenance of Hospital Ventilation

by Alison Withers

The hospital facilities manager may not be directly involved in medical treatment but they could still be seen as part of its healthcare team because the role includes maintaining high standards of hygiene and efficiency in the building's ventilation systems.

It is well known that ventilation systems accumulate dust, which is a mixture of organic compounds containing a high proportion of skin and hair, both valuable nutrients for the growth of micro-organisms that can then easily become airborne The UK's Department of Health has a set of guidelines specially for the construction and maintenance of ducted air systems, called Health Technical Memorandum 03-01.

The transmission of airborne infection is a crucial issue for hospitals, where patients are particularly vulnerable to infection. Maintaining good air hygiene in hospitals is therefore an essential part of its cleaning regime.

hygiene is hospitals is a critical part of its cleaning regime therefore. So while they may not directly transmit from person to person through the air, any skin particles that collect as dust in ducting systems and other hard to clean places could potentially be a risk to patients.

Tuberculosis (TB; Mycobacterium tuberculosis), on the other hand, is transmitted in the air and can be a source of outbreak in hospitals.

It is known that ductwork systems gather dust which is a mixture of organic compounds containing a high proportion of skin and hair, both valuable nutrients for the growth of micro-organisms that can then easily become airborne

The UK's Department of Health has a set of guidelines specially for the construction and maintenance of ducted air systems, called Health Technical Memorandum 03-01.

In the first part is a list of specifications for the construction of air duct systems in hospitals, but it may not be either practical or affordable for an existing hospital to replace an existing air duct system and the memorandum's second part lays down specific rules for their inspection and maintenance to ensure.

The first part contains a list of specifications for the construction of air duct systems in hospitals, but it may not be either practical or affordable for an existing hospital to replace an existing air duct system and the second part of the memorandum lays down specific rules for their inspection and maintenance to ensure ventilation hygiene.

It says that all ventilation systems should be have at least a simple visual inspection annually to ensure that it conforms to the minimum standards and that its general condition is fit for its purpose and operating effectively.

Critical systems, such as those serving operating theatres, intensive care and neonatal units and areas that must be kept sterile, such as laboratories and scanning facilities, must be inspected quarterly.

Inspections should ensure adequate air exchange rates and air quality and that ductwork seals and filters are fully functional.

It could be argued that the hospital's facilities manager or engineer therefore plays a crucial role in ensuring the health and safety of patients while in hospital and their recovery from illness as quickly as possible because it is part of their role to ensure that the air quality standards are kept as high as possible.

Therefore a regular regime of inspection, ventilation cleaning and filter maintenance is an essential part of patient care and best carried out by a specialist cleaning contractor fully conversant with all the latest rules and regulations specific to hospital ventilation systems.
