What is the OSHA standard for disinfecting blood?
In December 1991, OSHA promulgated a standard entitled “Occupational Exposure to Bloodborne Pathogens” to eliminate or minimize occupational exposure to bloodborne pathogens 214. One component of this requirement is that all equipment and environmental and working surfaces be cleaned and decontaminated with an appropriate disinfectant after contact with blood or other potentially infectious materials. Even though the OSHA standard does not specify the type of disinfectant or procedure, the OSHA original compliance document 269 suggested that a germicide must be tuberculocidal to kill the HBV. To follow the OSHA compliance document a tuberculocidal disinfectant (e.g., phenolic, and chlorine) would be needed to clean a blood spill. However, in February 1997, OSHA amended its policy and stated that EPA-registered disinfectants labeled as effective against HIV and HBV would be considered as appropriate disinfectants “. . . provided such surfaces have not become contaminated with agent (s) or volumes of or concentrations of agent (s) for which higher level disinfection is recommended.” When bloodborne pathogens other than HBV or HIV are of concern, OSHA continues to require use of EPA-registered tuberculocidal disinfectants or hypochlorite solution (diluted 1:10 or 1:100 with water) 215, 228. Studies demonstrate that, in the presence of large blood spills, a 1:10 final dilution of EPA-registered hypochlorite solution initially should be used to inactivate bloodborne viruses 63, 235 to minimize risk for infection to health-care personnel from percutaneous injury during cleanup.

Why do doctors use endoscopes?
Physicians use endoscopes to diagnose and treat numerous medical disorders. Even though endoscopes represent a valuable diagnostic and therapeutic tool in modern medicine and the incidence of infection associated with their use reportedly is very low (about 1 in 1.8 million procedures), 97 more healthcare–associated outbreaks have been linked to contaminated endoscopes than to any other medical device. 6-8, 12, 98 To prevent the spread of health-care–associated infections, all heat-sensitive endoscopes (e.g., gastrointestinal endoscopes, bronchoscopes, nasopharygoscopes) must be properly cleaned and, at a minimum, subjected to high-level disinfection after each use. High-level disinfection can be expected to destroy all microorganisms, although when high numbers of bacterial spores are present, a few spores might survive.

Key messages
Thorough cleaning is important for infection control – particularly in work areas – because deposits of dust, soil and microbes on surfaces can transmit infection.
Cleaning – general procedures
Cleaning is important for infection control – particularly in work areas – because deposits of dust, soil and microbes on surfaces can transmit infection. Contaminated areas such as operating rooms or isolation rooms must be cleaned after each session, and spot cleaned after each case or thoroughly cleaned as necessary.
Cleaning – specific procedures
Floors in hospitals and day-care facilities should be cleaned daily or, as necessary, with a vacuum cleaner fitted with a particulate-retaining filter. The filter should be changed in accordance with the manufacturer’s instructions.
Waste disposal
All healthcare facilities should have policies and procedures in place for the correct management of all waste generated. The Environmental Protection Authority (EPA) has clear guidelines on how waste should be managed.
