Cleaning & Decontamination of Ebola on Surfaces Pt 2

Guidelines for waste disposal

• Soak materials and PPE used in cleanup and decontamination in disinfectant, double-bag, and place in a leak-proof container to further reduce the risk of worker exposure. Use a puncture-proof container for sharps.
• It may be necessary to dispose of contaminated objects with porous surfaces that cannot be disinfected.
• Dispose of waste from surface cleanup in accord with CDC guidelines and the U.S. Department of Transportation’s (DOT) Hazardous Materials Regulations (HMR), at www.cdc.gov/vhf/ebola/hcp and phmsa.dot.gov/hazmat/transporting-infectious-substances.

Use appropriate respiratory protection

• In instances where workers may be exposed to bio-aerosols (e.g., as a result of spraying liquids or air during cleaning) suspected of or known to contain Ebola virus, additional respiratory protection is needed. In these cases, medically qualified workers must use, at a minimum, a NIOSH-approved, fit-tested N95 respirator.
• Wearing a respirator for extended periods of time can be uncomfortable. Workers who need respirators for long durations may find powered air-purifying respirators more tolerable.
• Respirators or face masks used for protecting workers against Ebola virus may not be effective for also protecting them from exposure to certain toxic chemicals used for cleaning and decontamination. To learn more about the requirements for selecting an appropriate respirator to protect against chemical exposure (elastomeric respirator with appropriate chemical cartridges or a supplied-air respirator), consult OSHA’s Respiratory Protection standard, 29 CFR 1910.134, and the manufacturer’s Safety Data Sheet (SDS) for the specific chemical(s) that workers are using. See OSHA’s Respiratory Protection web page: www.osha.gov/SLTC/respiratoryprotection.
