CDC Recommends Bleach to Lessen Risk of HBV Decontamination

The Centers for Disease Control and Prevention (CDC) states that Hepatitis B Virus (HBV) can survive for at least one week in dried blood on environmental surfaces or contaminated needles. Therefore, it is very important to decontaminate work surfaces immediately after spills occur. Protective coverings may be used on work surfaces to contain spills, but the surface must be decontaminated at the end of each work shift. A 1-to-10 solution of household bleach, prepared daily to ensure strength, is considered an appropriate disinfectant for workplace surfaces. Store the solution in a heavy plastic container (type 2 high-density polyethylene, or HDPE, not in glass).

When cleaning up a spill, wear personal protective equipment including a cover gown of fluid resistant material and safety goggles or a facemask. Heavyweight, puncture-resistant utility gloves such as those used for house cleaning or dishwashing are recommended. If the spill contains broken glass or other objects, remove and discard the debris prior to cleaning the spill. Use tongs and forceps or a brush and dustpan to pick up solid debris
