Garments worn as personal protective equipment must meet the American Society for Testing and Materials (ASTM) standards. This will ensure that the wearer will not be contaminated if there is a splash or splatter of blood or other potentially infectious material. The outer protective garment should be fluid-resistant, such as a nonwoven gown or a long-sleeved, cuffed laboratory coat with high resistance to fluid penetration. The lab coat should be fully closed when working in the laboratory.
Scrub suits do not offer adequate protection.
If a garment is contaminated with blood, it must be removed immediately or as soon as it is feasibly possible.
