Department of War U.S. Army Contracting Command-Aberdeen Proving Ground (ACC-APG) Natick Contracting Division (NCD) SUBJECT: Amendment 0002 to Call for Solutions (CFS) W911QY-26-S-PPTS-02 and Associated Statement of Objectives (SOO) PROJECT TITLE: Portable Patient Transport System (PPTS) DATE: 14 July 2026

1. Purpose of Amendment The purpose of this second amendment is to formally modify the Filter Certification requirements detailed in both the Call for Solutions (CFS) and the Statement of Objectives (SOO).

Specifically, the Government is clarifying that system-level "HE" (Powered Air-Purifying Respirator - PAPR) certification is not required for the transport enclosure. The Government is explicitly broadening the acceptable standard to allow for component-level National Institute for Occupational Safety and Health (NIOSH) certified filters (e.g., P100) or recognized equivalent international standards (e.g., EN1822 H14) to ensure maximum technical flexibility and industry participation.

2. Description of Changes The following changes are hereby incorporated into the CFS and the SOO. All other terms, conditions, and requirements of the original Call for Solutions and previous amendments remain unchanged and in full effect.

Change 1: Call for Solutions (CFS) Update

Change 2: Statement of Objectives (SOO) Update
