Table 1: Various classifications of pressure dependent spaces used as at Texas Children's Hospital
Classification of Pressure
Dependent Spaces

Parameters Required to
be Monitored

Monitoring

Examples

1

Pressure, temperature, humidity,
and air changes per hour

Centralized and local

Operating room,
procedure room, pharmacy

2

Pressure and/or air
changes per hour

Centralized and local

Isolation room, clean room

3

Pressure

Local only

Soiled utility, food, and nutrition

4

Pressure

Local and temporary

Construction zones

Texas Children's Hospital updated the institutional space
management policy to reflect the adopted standards and
outlined an approved process for repurposing space.
A master list of all pressure dependent spaces was
created based on present usage. A list had already existed;
however, the following had happened to invalidate
the information:
1. The present use of a space in various departments was
different from it is original design intent. For example, a
space designed as storage was now being used as clean
storage. In other cases, spaces that were designed as
pressure dependent spaces were now used for purposes
that did not require the space to be pressure dependent.
2. Some room numbers had changed or were missing from
the list.

3. Spaces that should be pressure dependent were not on the
existing list. For example, a soiled utility room should be a
negatively pressurized space, but was not included in the list
of pressure dependent spaces.
After the new list had been prepared and verified, the
team determined that the master list should be maintained
by the facility department and updated once every year for
correctness and completeness.
The next step was to identify what is required to be
monitored in these spaces (for example, pressure, temperature,
humidity, and air changes per hour). Based on these
requirements, and the criticality of the space, a matrix was
created to show if monitoring would be local, remote, or both,
and what data was to be obtained and at what frequency. The
classification scheme created by the task force is shown in
Table 1.
Based on the requirements identified for implementation,
an audit was carried out for all pressure dependent spaces to
ensure that these spaces are being used as pressure dependent
spaces and that the signage outside these spaces conforms
to the standard naming scheme as adopted by the hospital.
This ensured agreement between the master list of pressure
dependent spaces, space utilization, and signage outside these
spaces. This audit also helped to document monitoring devices
that are physically present and whether a monitoring device
was present.
After the space audit was performed, a plan was prepared
to monitor these pressure dependent spaces in an effort
to conform to the regulatory requirements. In some
situations several monitoring devices had to be installed and
remotely or locally monitored, as well as alarms set in case
the attributes like pressure, temperature, humidity, or air
changes per hour did not meet specifications. To effectively
manage installation of monitoring devices, this project was
implemented in a phased manner based on availability of
resources and time.
An annual audit of these spaces by users, and a sample audit
of these spaces by the facility department is recommended.
As space is being repurposed or added, specifications will be
integrated in the design and construction.
A training program will be established so all stakeholders
understand their roles, the requirements for each room, the
process for repurposing spaces, and the regulatory requirements
related to the pressure dependent spaces.
