The cryogenic storage room is one of the most critical spaces in an IVF facility. Its design and equipping must satisfy both the HFEA regulatory requirements and broader health and safety obligations under UK law.
Ventilation is among the most important considerations. Liquid nitrogen evaporation in an enclosed space can displace oxygen to dangerous levels. The room must have adequate ventilation to prevent gas accumulation under normal operating conditions. The ventilation system must be independent from other areas of the facility.
Oxygen depletion monitors are mandatory safety equipment in any room where significant liquid nitrogen volumes are stored. They must be positioned at low level, calibrated and tested regularly, and must trigger an audible and visual alarm when oxygen drops below set thresholds.
Floor loading must be assessed. A full 35-litre stainless steel dewar may weigh 30 to 40 kilograms. A room with multiple large dewars represents a substantial concentrated load that the floor structure must support.
Electrical installations must be appropriate for the environment. Condensation around cryogenic vessels can be significant in warm weather.
The room must be lockable to prevent unauthorised access but accessible to authorised staff at all times for nitrogen top-ups and alarm responses.
Monitoring systems including nitrogen level sensors must be hardwired rather than relying on wireless connectivity for the alarm function, as wireless systems are vulnerable to connectivity gaps.
