Work Boot Safety is a Requirement on Dangerous Work Sites If you are working at a job that requires the wearing of safety toe footwear, it is crucial that you follow your employer’s regulations in order to protect your feet, and for that matter, even possibly your life.įoot, ankle and knee injuries can always be life-changing events, both physically and financially, but they are especially life-changing if the proper safety precautions are not followed if you are injured while on the job. A common misunderstanding among many end-users is that they are protected from blood, body fluids, and other potentially infectious materials (OPIM) when they wear any type of fluid-resistant garment or surgical or isolation gown.ASTM Safety Standards | Expert Guide to Work Boot Safety in 2021įootwear needs to be tough enough to protect feet in today’s high-intensity work environments. Therefore, no correlation can be made between AATCC water resistance tests (AATCC 42 and AATCC 127) and ASTM F1671 viral penetration tests, and consequently, protection provided by Levels 1, 2, 3 gowns and that of Level 4 gowns. Because the surface tension of water is much higher than that of blood, blood can penetrate through fabrics more readily than water. ANSI/AAMI PB70 Level 1, 2, and 3 surgical/isolation gown-testing requirements only use water as a challenge. However, Level 1–3 gowns can provide increasing resistance to liquids. The gowns complying with the lower levels (Level 1, 2, and 3) cannot be considered impermeable. Only Level 4 gowns are tested for viral penetration resistance, and therefore only Level 4 garments are considered impermeable to viral penetration using ASTM F1671.

Minimal water resistance (some resistance to water spray) Table 3: ANSI/AAMI PB 70:12 classification of barrier performance of surgical gowns, other protective apparel, surgical drapes and drape accessories Table 3 summarizes the requirements of ANSI/AAMI PB70:2012 regarding the classification of barrier performance of surgical gowns, isolation gowns, and surgical drapes.

Based on the results of these standardized tests, four levels of barrier performance are defined, with Level 1 being the lowest level of protection, and Level 4 being the highest level of protection. The ANSI/AAMI PB70 standard includes four standard tests to evaluate the barrier effectiveness of surgical gowns, isolation gowns, and surgical drapes.
