Nursing Home Exhaust

[dblyle]

I currently have a client that was sited by the Texas Dept. of Aging and Disability Services for not having mechanical ventilation in his linen storage closets, Oxygen closet, nursing supply closet, and dry storage in the kitchen. Some of these I understand, however I am not sure I know the rational behind ventilation (i.e. exhaust; he has supply) in the linen storage and dry storage closet.

Texas Administration Code (code that was cited) just says that the client must provide fresh air. Does anyone know what codes apply to these rooms in a nursing home? ASHRAE doesn't seem to have much on it and I haven't found much in the IBC or the UMC (Houston uses the Uniform Mechanical Code).

Also, does anyone have any design suggestions for these rooms? I was hoping to find codes that dictate positive or neg pressures, etc, to define my design parameters.

Thanks in advance!!!

The code is AIA/HHS heatlthcare design guidelines, it will show you which room requires positive or neagtive pressure and will indicate ACH/OA ACH, etc.
Oxygen closets are better located against an Outside wall with high and low louvers using natural ventilation, mechaincal evntilation will require explosion proof motors.
Dry storage in kitchen is handled by using a small DX split system for 24-hour cooling (to keep bugs from your rice,etc.)
