Standards for making PPE and other Medical Devices during COVID-19

Specifications for Manufacturing of Face Shields

In lieu of limited access to Face Shields, Health Canada has provided the following guidelines that manufacturers should comply with. The standards outlined below are the minimum specifications that should be incorporated into the design and verification of face shields:

• Device must provide adequate coverage (CSA Z94.3 Sections 10.2.1/10.2.2/10.3/10.4).
• Device should made of optically clear, distortion free, lightweight materials (refer to CSA Standard Z94.3.1-16)
• Device should be free of visible defects or flaws that would impede vision (ANSI Z87.1 Section 9.4)
• The device should allow adequate space between the wearer’s face and the inner surface of the visor to allow for the use of ancillary equipment (medical/surgical mask, respirator, eyewear, etc.).
• Device should fit snugly to afford a good seal to the forehead area and to prevent slippage of the device
• Device should withstand impact from sharp or fast projectiles (ANSI Z87.1 Section 9.2 and 9.3, CSA Z94.3 Section 10.1)
• If available, device should display anti-fog behavior on inside and outside of shield. (CSA Standard Z94.3.1-16)
• User contacting materials should provide adequate material biocompatibility (skin sensitivity and cytotoxic testing) (ISO 10993-5, 10)
