Mortuary and autopsy rooms require fume extraction fans to exhaust any hazardous substances and odours out of the room via a downdraft ducting system. Polypropylene fans can withstand harsh chemicals and vacuum any toxic particles down through the ducting and out to atmosphere. It is vital that all the guidelines are met in this sector to ensure the health and safety of staff and visitors.
A post mortem room requires a fresh air supply introduced at high level, above the observation area so to not cause discomfort to staff or visitors or interrupt the air flow pattern provided by down draft benches. The minimum recommended total fresh air supply rate to a post mortem room is 10 air changes per hour. As stated by the Department of Health the ventilation system of a mortuary should be designed to minimise the spread of odours and airborne pathogens by being isolated from other ventilation systems, where possible.
Downdraft Ventilation Equipment in Morgues and Autopsy Rooms
Downdraft benches with adequate ventilation are necessary equipment in morgues and autopsy rooms for handling formalin-fixed organs and tissues. There are many reports of hazardous xylene, formaldehyde and hot paraffin fumes being present in autopsy laboratories and very little documentation on installing an efficient fume extraction system. It is crucial to have the correct equipment in your system installation to efficiently remove the harmful toxins.
Downdraft benches ventilate the air across the top of the bench and out through a rear extract. This reduces the risk of staff or visitors inhaling any toxic fumes during or after any processes. Downdraft benches that extract air from the front to the rear are favoured over downflow benches as staff can easily interrupt the air flow if it flows straight down beneath them as they work. If the air flow is interrupted the whole system would be less efficient. It is important the air can constantly flow and that systems are meeting all the criteria.

Corrosion Resistant Polypropylene Fans
Corrosion resistant polypropylene fans are best suited to handle the use of formaldehyde within this type of environment as they can withstand harsh chemicals without rusting or corroding. Maintenance of the downward draft fume extraction systems is crucial for mortuary and autopsy rooms due to the risk of staff and visitors contracting infectious diseases from airborne droplets, the cacogenic nature of preservatives chemicals and to eliminate any build up of foul odours. There are certain regulations that must be met according to the latest guidelines set by COSHH. When considering the build of a fume extraction system it is important to ensure there is no risk of reintroduction of the exhausted air being blown back into the building through vents or windows so the positioning of the fans and ducting is crucial.
The Axair ‘S’ range fans are designed to provide high air flow rate against medium system pressures.
The Axair STORM ‘ST’ range fans are designed to provide a relatively low air flow rate against elevated system pressures.
The ATEX ranges are available for Category 3G Zone 2 applications and can be supplied with EEx nA or EEx d motors to order.
