A biological safety cabinet (BSC) is a primary engineering control used to protect personnel against biohazardous or infectious agents and to help maintain quality control of the material being worked with as it filters both the inflow and exhaust air.
What does a biological safety cabinet do?
Biosafety cabinets (BSCs) are one type of biocontainment equipment used in biological laboratories to provide personnel, environmental, and product protection.
How are engineering controls used in a laboratory?
Engineering controls are OSHA’s preferred method in dealing with laboratory hazards. These controls remove or reduce exposure to a chemical or physical hazard by using or substituting engineered machinery or equipment. Examples include the following: Selection of a less toxic chemical.
What is an example of an engineering control?
Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Examples include local exhaust ventilation to capture and remove airborne emissions or machine guards to shield the worker.
What are engineering controls in bloodborne pathogens?
Engineering Controls means controls (e.g., sharps disposal containers, self-sheathing needles, safer medical devices, such as sharps with engineered sharps injury protections and needleless systems) that isolate or remove the bloodborne pathogens hazard from the workplace.
Why engineering controls and administrative controls are important for biosafety?
* Engineering controls are used to remove a hazard or place a barrier between the employee and the hazard. Administrative controls are changes in work procedures with the goal of reducing the duration, frequency, and severity of exposure.
What is the function of biosafety cabinet quizlet?
A Biological Safety Cabinet is a ventilated cabinet which uses a combination of HEPA filtration, laminar air flow and containment to provide either personnel, product or environmental protection or protection of all components against particulates or aerosols from bio-hazardous agents.
What do all biosafety cabinets have in common?
There are 3 main classes of Biological safety cabinets (BSCs) – the thing they all have in common is that they protect the worker/environment from the cultures.
What is biological safety cabinet list its types?
There are three kinds of safety cabinets, Classes I, II, and III. Class II and Class III biological safety cabinets provide personnel, environmental as well as product protection. Whereas the class I safety cabinet, which is the most basic one, provides personnel and environmental protection only.
What is an example of an engineering control for worker protection?
Engineering controls are physical changes to the workplace and may include equipment guarding, guardrails, traffic control lanes and barriers between vehicles and pedestrians, and many other options.
Is a fire extinguisher an engineering control?
Appropriate and mandated engineering controls include ventilation, fume hoods, fire extinguishers, eyewash stations, and safety showers.
What is chemical safety engineering?
The Chemical Safety Engineering department concerns itself with explosive, flammable or otherwise dangerously reactive substances, systems and products – especially in relation to national, European and international regulations of hazardous substances, hazardous goods and explosives legislation and of product safety …
What are the 4 engineering controls?
Engineering controls consist of a variety of methods for minimizing hazards, including process control, enclosure and isolation, and ventilation. Process controls involve changing the way that a job activity is performed in order to reduce risk.
Which items are engineering controls?
Engineering Controls: includes designs or modifications to plants, equipment, ventilation systems, and processes that reduce the source of exposure.
Is lockout/tagout an engineering control?
The lockout tagout system, as prescribed under OSHA CFR 1910.147 and 1910.147 App A, is comprised of two parts: an engineered method of hazardous energy control, and an administrative method whereby direct and indirect employees are trained to apply the engineered methods or are trained not to touch or remove any …
What is an example of engineering control you should use to avoid BBP exposure?
Engineering controls, when feasible, are considered the first line of defense for avoiding exposure to bloodborne pathogens. Examples of engineering controls are safe needle devices or lab equipment like sealed centrifuge rotors. Biosafety cabinets are used in labs working with human blood or OPIM.
Is a hand washing station an engineering control?
Engineering controls, including facilities for hand washing, must be maintained or replaced on a regular schedule to ensure their effectiveness. When handwashing facilities are not available, an antiseptic hand cleanser should be provided.
Which of the following is an example of an engineering control you should use to avoid BBP exposure?
Engineering controls are the primary means of eliminating or minimizing employee exposure and include the use of safer medical devices, such as needleless devices, shielded needle devices, and plastic capillary tubes.
What is the difference between engineering controls and administrative controls?
Engineering controls might include changing the weight of objects, changing work surface heights, or purchasing lifting aids. Administrative controls are workplace policy, procedures, and practices that minimize the exposure of workers to risk conditions.
What are the 5 control measures?
Key points. NIOSH defines five rungs of the Hierarchy of Controls: elimination, substitution, engineering controls, administrative controls and personal protective equipment.
What statement best defines engineering control practices?
The basic concept behind engineering controls is that, to the extent feasible, the work environment and the job itself should be designed to eliminate hazards or reduce exposure to hazards.
What are the three types of protection provided by biological safety cabinets?
Classes of biological safety cabinets There are three classes of BSCs: Class I, II and III. While all three classes afford personnel and environmental protection, only Class II and III cabinets provide product protection. Class I BSCs are suitable for work involving low to moderate-risk agents.
How does the BSC provide the 3 types of protection?
How do Biological Safety Cabinets differ from Chemical Fume Hoods? Class II BSCs provide personnel, product, and environmental protection from biohazards by removing particulates, using HEPA filters. BSC’s recirculate a portion of the air and may or may not exhaust to the outside.
Where should biological safety cabinets be located?
BSCs should be located out of the laboratory personnel traffic pattern. Preferably they are placed at the end of an aisle. BSCs should not be placed near an entryway. If this cannot be avoided they should be placed at least 60″ from behind the doorway or 40″ from an adjacent door.
Which biosafety cabinet is best?
The Class II, Type C1 Biosafety Cabinet offers the greatest combination of safety and flexibility, and is therefore the “no-brainer” choice in most circumstances.
