From the document:

"If (intravenous) solutions must be stored within the EMS facility, the agency must first obtain a CSR for the purpose of storing these solutions in the EMS facility at the address on the application."

Unclear why IV solutions would be specifically called out to address in-station storage when there is a long list of regulated medical equipment (such as needles, IV catheters etc) that require similar protections for secure storage. Additionally, requiring a separate CSR for the sole purpose of storing these medical supplies creates a high regulatory burden for larger EMS agencies with multiple stations under a single agency umbrella.
