Engineering Controls: any device that is used to prevent contact with or exposure to the hazard (e.g. chemical fume hoods; splash guards, guards on moving parts; barriers; monitoring devices, safety interlocks.

What does a biosafety cabinet do?
Biosafety cabinets (BSCs) are one type of biocontainment equipment used in biological laboratories to provide personnel, environmental, and product protection.
Is a chemical fume hood an engineering control?
Engineering controls are anything that that is built or installed to separate people from chemical, biological or physical hazards, and can include fume hoods, biosafety cabinets, glove boxes, and blast protectors.
What is the purpose of a biosafety cabinet in a microbiology laboratory quizlet?
(BSCs)? 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 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 the 5 types of engineering controls?
- 2.1 Ventilation. 2.1.1 Local exhaust ventilation. 2.1.2 General exhaust ventilation. 2.1.3 Control verification.
- 2.2 Containment.
- 2.3 Other.
What are biological cabinets?
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.
Is biological safety cabinet a medical device?
Biological Safety Cabinets (BSCs) are among the most common and effective primary containment devices used in laboratories to protect individuals from splashes and aerosols when working with biological agents.
What is the importance of using biosafety cabinet when performing laboratory?
The primary purpose of biosafety cabinets is to protect the laboratory personnel and the environment from the pathogenic microorganism as aerosols might be formed during the processing of such microorganisms.
Are gloves An example of engineering control?
Hazard Control: Personal Protective Equipment (PPE): Hand Protection (Gloves) Engineering Controls – which remove hazards from the worker environment – are the first line of defense against exposure to workplace hazards.
Are eyewash stations engineering controls?
Most, if not all secondary level science laboratories require engineering controls such as eyewash and showers. This is dictated by direct contact or exposure to hazardous chemical products, which can harm eyes or other body surface areas.
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.
Which of the following is an example of engineering control quizlet?
A guard placed around the perimeter of a conveyor is an example of an engineering control. At the winery, part of Alain’s job involves being lowered through a narrow opening into a giant tank to clean it out in between batches.
Is a biosafety cabinet a primary containment?
Primary containment devices include biological safety cabinets (BSCs), isolators, local exhaust ventilators and ventilated working spaces.
What are the three types of protection provided by biological safety cabinets?
The vertical laminar flow Biological Safety Cabinet provides operator protection by means of inflow, product protection by means of down flow and environmental protection by means of the filtered exhaust.
What are 3 engineering controls?
A. The engineering control methods that can be used to reduce or eliminate lead exposures can be grouped into three main categories: (1) substitution; (2) isolation; and (3) ventilation. Engineering controls are the first line of defense in protecting workers from hazardous exposures.
What are four examples of common engineering controls?
Examples include self-capping syringe needles, ventilation systems such as a fume hood, sound-dampening materials to reduce noise levels, safety interlocks, and radiation shielding.
Is PPE considered an engineering control?
Engineering controls. Administrative controls. Personal protective equipment (PPE)
What are common engineering controls?
The basic types of engineering controls are: Process control. Enclosure and/or isolation of emission source. Ventilation.
What are engineering controls quizlet?
Engineering controls. objects used in the workplace that isolate or remove a hazard, thereby reducing the risk of exposure. Engineering controls include. Biohazard bags and labels. PPE.
What is the difference between engineering control and administrative control?
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 is the difference between laminar flow cabinet and biological safety cabinet?
A Laminar Flow Hood (LFH), is not a biological safety cabinet. These devices do not provide any protection to the worker. They are designed to provide a sterile environment to protect the product. Air potentially contaminated with infectious agents may be blown towards the worker.
Is a biosafety cabinet a fume hood?
A chemical fume hood is designed to remove chemical fumes and aerosols from the work area while a biosafety cabinet is designed to provide both a clean work environment and protection for employees who create aerosols when working with infectious agents or toxins.
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 do all biosafety cabinets have in common?
There are 3 main classes of Biological safety cabinets (BSCs) โ the thing they all have in common is that they protect the worker/environment from the cultures.
