N.Y. Comp. Codes R. & Regs. tit. 9, § 303.3 – Location of AEDs.

(a) Subject to the phased-in implementation of AEDs, each State agency shall endeavor to have sufficient AEDs available at each of its public buildings to ensure ready access for use during emergencies.
1. (1) Each State agency's phased-in implementation plan shall commence by prioritizing AED placement in those public buildings that house the largest number of State employees, other intended occupants or estimated regular visitors, or which the State agency reasonably deems to merit priority treatment due to the high risk nature of the population served or the activities conducted at the public building.
2. (2) When prioritizing AED placement as described in paragraph (1) of this subdivision, those public buildings where there is a greater level of physical activity or in which a higher occupant density is likely shall be given priority for AED placement over public building(s) that have a lower level of physical activity or lower likely levels of occupant density.
3. (3) Public buildings housing a staff, other intended occupants or regular visitors of 100 people or more shall be considered priority structures for the implementation of an AED program.
(b) After a State agency has prioritized its public buildings for purposes of implementing an AED program, the agency shall determine the quantity and placement of AEDs. In implementing the physical placement of the AEDs, consideration shall be given to the size and physical layout of the public building, including but not limited to the following factors:
1. (1) placement of AEDs in centralized locations based upon the response system an agency has established in its PAD plan, or mobile deployment of AEDs (e.g., placement of AEDs in emergency vehicles), such that a trained operator could optimally respond to the site of a cardiac event with an AED at or about an agency's public building(s) in a period of not more than three minutes;
2. (2) locations of stairways and elevators;
3. (3) number of floors in the facility;
4. (4) security features that limit access or restrict freedom of movement to certain areas of a building;
5. (5) conspicuous location for AED access and retrieval; and
6. (6) protection of the AED against accidental physical damage, tampering or theft.
(c) AEDs should not be located in locked rooms or where access is restricted, unless the AED is meant to be an additional device or is secondary to the AEDs installed for regular daily access. Notwithstanding the foregoing, where placement of an AED may be problematic due to security or other safety considerations, or where the combined logistics of building design, risk level and operator availability reasonably indicates a secure AED placement, the State agency may consider alternate installations that are as consistent as possible with these rules and regulations.
(d) An agency shall consider AED options for children in those State facilities that are regularly open to the public, e.g., museums, convention centers, recreational/sport facilities. Appropriate AED equipment options should be acquired and made available for resuscitating children in accordance with AED manufacturer's recommendations.
