Critical PPE Manufacturing Designs/Specification/Instructions

Below is a compiled list of available manufacturing information for Critically Needed Medical PPE. This information has been provided by various third-party sources (companies, universities, industry experts, and volunteer groups), and as such, Purdue University cannot provide any guarantees on the accuracy and reliability of the information provided. The information is provided as a reference, and individual companies should conduct their own independent vetting process before deciding to use this information. This list will be updated as new manufacturing information becomes available, so please check back regularly.

Isolation Suits/Gowns: (will re-direct to Google Drive)

Below is an open-source document for making isolation suits.  The document contains design info, bill of materials, patterns, construction details, and assembly instructions:

Isolation Suit Manufacturing Document

Notes: This design produces a working isolation suit if seams are sealed. The recommended material is Tyvek 1433R. Sewing seams make the garment more permeable because of needle holes; an only-sewn suit should not be used to treat active patients. Please read through the techpack for full construction details based on what kind of machine you have accessible. Dupont has a guide for seaming & sealing Tyvek to itself in order to make sealed seams. Heat sealing the outer edge at 120-130°C before sewing would result in more-sealed, more-robust seams.

Alcohol-Based Hand Sanitizer: 

Temporary policy and production guide for manufacturers producing alcohol-based hand sanitizer products during the public health emergency (COVID-19). Notes: Effective as of December 31, 2021, the FDA withdrew its guidance for the manufacturing of alcohol-based sanitizer products during COVID-19. Reference this page for more information.
