Safety cabinet protection level

Increased product protection is the middle of the three levels. This can be carried out in a clinical area in a separate room within a laminar airflow (LAP) or safety cabinet or isolator by a member of pharmacy staff or by a nurse or doctor. 

Maximum product protection is the highest of the three levels of product protection. In this case the aseptic activity is carried out within a LAF or safety cabinet or isolator sited within at least an EU Grade D of controlled background in the hospital pharmacy. 

Protection of the worker from nuisance levels of work-generated dusts, vapors, or other contaminants that cannot be captured in a biological safety cabinet or in a fume hood. (Of course, whenever possible the respiratory hazard should be eliminated from the work environment.)... 

BSL 2 Biosafety Level 2 is suitable for work involving microorganisms of moderate potential hazard to personnel and the environment. Safety equipment Class I or II biosafety cabinets or other physical containment devices laboratory coats, gloves, face protection as needed. Microorganisms include hepatitis B virus, HIV, salmonellae, and mycoplasma. 

The ex-vessel neutron detection equipment consists of fission chamber neutron detectors mounted in six equally spaced vertical wells located just outside the reactor vessel as illustrated in Figure 4.3-4. The signals from these detectors are supplied to the nuclear instrumentation cabinet and Safety Protection Subsystem equipment located primarily in the reactor building. These data are used by the automatic control systems to operate the control rod drives or the reserve shutdown equipment, thereby changing the neutron flux levels within the reactor core. 

Assessment, 1996 Cabinet Office, 2002 British Standards Institute, 1996 Standards Australia, 1999 Health and Safety Executive, 2001 Institute of Risk Management, 2002 National Infrastructure Protection Centre, 2002), but there are three essential steps in all these frameworks. First, the threats faced by an organisation and their possible consequences are identified and catalogued. Second, risk levels are calculated for each threat by assessing the likelihood and the severity of the harmful consequences or outcomes that might result. Third, these risk levels are compared to a predetermined criteria or level of acceptability, and unacceptable risks are selected for action or treatment. The process is then to be repeated as an ongoing cycle.
