Patient health and safety is at the forefront of design considerations, but a challenge faced by many HVAC designers is a lack of guidance as to what types of air inlets and outlets should be installed in these unique spaces.   ![The hallway of a mental health facility](https://blog.priceindustries.com/hs-fs/hubfs/GettyImages-1295775470_crop.jpg?width=3861&height=2387&name=GettyImages-1295775470_crop.jpg)   The [New York State Office of Mental Health](https://on.ny.gov/3uVglOT) (NYS-OMH) has emerged as a key influencer in this domain, providing the reference document *[Patient Safety Standards, Materials and Systems Guidelines](https://on.ny.gov/4bUiPxA)* to serve as a compass for the HVAC engineers designing these spaces. Although the document originates from a New York organization, its influence is international, underscoring the growing need for best practices for designing mental health and correctional facilities.   Products reviewed and accepted by the NYS-OMH are detailed in the document, with risk-assessment ratings for high-, medium- and low-risk areas. It is important to note that these risk assessment categories are guidelines and that selecting products in those categories does not eliminate all risks; every product should be evaluated for suitability according to the project requirements.   | ![Front cover of Patient Safety Standards, Materials and Systems Guidelines](https://blog.priceindustries.com/hs-fs/hubfs/NYS-OMH%20Document2.jpg?width=948&height=569&name=NYS-OMH%20Document2.jpg) | | --- | *Patient Safety Standards, Materials and Systems Guidelines* is available on the [NYS-OMH website](https://on.ny.gov/4bVGOMX) NYS-OMH revised its guidelines on January 31, 2024, to keep current with ongoing product development and innovation. For the HVAC section, there was a focus on perforated air inlets and outlets and their designated risk assessment. The revisions state that for renovations, perforated grilles remain acceptable for high-risk areas; however, for new construction projects, these grilles should be considered only for medium-risk areas. Based on these changes, in new construction projects, only louvered security grilles and diffusers should be used in high-risk areas. | ![Perforated Linear Security Diffuser](https://blog.priceindustries.com/hs-fs/hubfs/MSPLD_v001_B_crop.jpg?width=600&height=417&name=MSPLD_v001_B_crop.jpg) | | --- | | Price’s [Perforated Linear Security Diffuser](https://bit.ly/3wv9VXt) |   Price industries has a range of security products that have been evaluated and deemed acceptable by NYS-OMH for areas with different levels of risk.   For high-risk areas: - The **Security Risk-Resistant Ceiling Diffuser** ([MSRRCD](https://bit.ly/48FtlGw)) features heavy-duty, all-welded construction and thread-resistant cores. - For renovations only, the **Security Perforated-Face Grille** ([MSPG](https://bit.ly/4bKxNpY)) reduces the risk of damage and disassembly, with all-welded construction and integral wall sleeves. - Also for renovations only, the one-way **Perforated Linear Security Grille** ([MSPLD](https://bit.ly/48zYBq2)) provides a safe alternative to traditional slot diffusers. For medium-risk areas: - For new builds, the **Security Perforated-Face Grille** ([MSPG](https://bit.ly/3uMJhsy)) is available with a variety of mounting types and is suitable for both supply and return applications. - For the **Perforated Linear Security Diffuser** ([MSPLD](https://bit.ly/3T26zCW)), both one- and two-way airflow patterns can be used.
