Biohazards containment

The architectural services integrate the design of the facility so that it can support the corresponding process the flows of people, materials, products and waste, product separation, sterile processing, sanitary design, biohazard containment, special utilities, and solvent recovery, handling and storage. 

Animal carcasses, bedding and absorbent material from bench tops should be wrapped in biohazard containers and prepared for disposal by incineration. 

Disposable labware, such as pipettes, should be autoclaved and placed in biohazard containers. Non-disposable labware should be retained in the facility until it has been decontaminated. 

A pharmaceutical company requires a ventilation system to purify the air of a biohazard containment laboratory. HEPA, ULPA, and SULPA technologies were considered but the ULPA filters were deemed sufficient for the particle size of the likely contaminants. The life span (in days) of the air filter given by the different suppliers is 80, 110, 100, 150, 170, 60,90,90,80, no, 90,110,80,90,160,110,90,210,160,120,110, and 110. A. R. Nassani...

Sometimes in the design of a BSL-4 facility, the full letter of health and safety codes/requirements for the protection of workers can not be met. This is where health and safety specialists must compromise and use their ingenuity to meet the intent of the requirements. For example, it is not always possible to provide a secondary means of egress from each area. Two change facilities are not cost effective or practical. A viable alternative is the use of airlocks with built-in liquid disinfection systems which are not hazardous to humans, but destroy the biohazard. These airlocks must be clearly identified as others are often used for transportation of equipment and other materials and contain hazardous disinfection systems. 

The exploitation of ambient fuels is attractive in situations where power needs for small electronic devices are distributed, disconnected, and long-term. This might be true for electronic sensor systems for monitoring of plant health, air quality, weather, or the presence of biohazards. In principle, the fuel can be derived from carbohydrates contained in plants or from effluent of human or animal processes. 

Less obvious are the biological and toxicological hazards from bomb scene debris. Apart from the possibility that malefactors may deliberately incorporate noxious substances in their devices, hazards can be generated from the scene itself For example, victims may have been suffering from an infectious disease, and so victims clothing (which is often soaked in blood) needs to be handled and stored with proper biohazard precautions. Scene debris may also contain dismembered body parts.

Additional considerations include vaccinations of investigators against rabies or tuberculosis, especially when working with some mammals and their parasites. These preventative measures are needed to protect the researcher. Animal necropsy should include protective clothing and the containment of possible biohazards, in order to avoid contracting diseases such as psittacosis, erysipelas, rickettsial infections, and brucellosis.5 The... 

All laboratories in which work with biohazardous materials is carried out must have labeled, leak-proof, covered containers for temporary holding of infectious materials awaiting disinfection or disposal. 

Biohazard level 4. Bolivian fever, Dengue fever, ebola, Hanta virus, Lassa virus, and other various hemorrhagic diseases (mostly of African origin). When dealing with biological hazards at this level the use of a Hazmat suit and a self-contained oxygen supply is mandatory, and the disease is studied and patient isolated in very rigorously self-contained environments. 

Biological samples including blood and urine may present health risks to the personnel collecting and analyzing the samples. When diverse blood samples are transported, received, or analyzed, every effort should be made to reduce the biohazards for laboratory staff (Truchaud et al. 1994 WHO 2003). Suitable containers or bags should be used to transport samples from the animal care buildings to the laboratory. Allergies to laboratory animals and their samples remain a risk for laboratory workers, and efforts should be made to minimize exposure to animal dander, etc. (Venables et al. 1988 Hunskaar and Fosse 1990 Cullinan et al. 1994 Wood and Smith 1999).

Contaminated sharps, discarding and containment Contaminated sharps shall be discarded immediately or as soon as feasible into containers (Figure 4.11) that are closable, puncture-resistant, leakproof on sides and bottom, and labeled according to the requirements of the standard. The latter usually requires a biohazard symbol on the container and/or the container being red. ...
