Which disinfectant is suitable for disinfection of biosafety cabinet?

Decontaminate the surfaces of the BSC with an appropriate disinfectant, such as a 10% bleach solution followed by 70% ethanol solution. If you have scheduled a specific time for the maintenance to be performed, a lab member should be available to meet with the certification technician.

Is a biological safety cabinet sterile?

BSCs work by purifying non-sterile ambient laboratory air through HEPA filtration.

How do you decontaminate fungi?

Thoroughly clean all surfaces with soap or a detergent or a diluted solution of AHP® and rinse with water. 5. Apply the AHP® solution to floors, walls and other surfaces of the cages, stalls or other animal handling areas ensuring the surfaces are thoroughly wet and allow to remain wet for the appropriate contact time.

What is the best method of decontamination?

All infectious materials and all contaminated equipment or apparatus should be decontaminated before being washed, stored, or discarded. Autoclaving is the preferred method.

How often does a biosafety cabinet need to be certified?

BSCs must be certified when installed, whenever they are moved and at least annually [29 CFR 1910.1030(e)(2) (iii)(B)].

What do you do in a biosafety cabinet?

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 are the guidelines to be followed while working at the biosafety cabinet?

  • Know Your Airflow.
  • Work at the Proper Sash Level.
  • Never Block the Airflow Grill.
  • Minimize Movement.
  • Reduce Splatter.
  • Know Your Work Area.

What is the disinfectant of choice when cleaning up spill of biological materials?

Biohazard Spill Clean-Up Materials: * A freshly prepared 10% bleach solution is effective for the decontamination of most biological spills. Some laboratories have the potential for spills involving agents or materials that may be resistant to a 10% bleach disinfectant.

How long should bleach remain in contact with a contaminated area after a hazardous spill?

Cover the spill with absorbent material (paper towels). Pour 10% bleach on the absorbent material and allow 20 minutes of contact time with bleach. Wipe the spill area, working from the edges towards the center to prevent spread of contamination. Place absorbent material in biohazard bag for disposal.

Which of the following is commonly available in a basic spill kit quizlet?

Can two people work in a BSC?

Never work with two or more people at a time in any BSC, regardless of manufacturer, model or size. Multiple users will cause air disruptions and potentially destroy the containment capabilities of the BSC, possibly creating personnel, product or environmental protection issues.

Should hands be washed before or after working in a biological safety cabinet?

Use an appropriate disinfectant to decontaminate work surfaces, equipment, instruments, and glassware daily and immediately after a spill. This includes a wipe down of the bio-safety cabinet if one is used. Wash hands after completing work and before leaving the laboratory.

Can bleach be inactivated?

detergent. Bleach is solely a disinfectant and can be inactivated by microscopic organic debris. Care must be taken to completely rinse all detergent residues and thoroughly dry the surface prior to applying bleach so as not to further dilute the bleach solution.

What are the types of biosafety cabinets?

What is HEPA filter in biosafety cabinet?

An essential component in any clean bench or biosafety cabinet is the high efficiency particulate air filter, commonly called a HEPA filter. The HEPA filter removes particulates (generally called aerosols) such as micro-organisms, from the air. The HEPA filter does not remove vapors or gases.

Which filter is being used in a biosafety cabinet?

The HEPA filter in the exhaust system of a biosafety cabinet will effectively trap all known infectious agents and ensure that only microbe-free exhaust air is discharged from the cabinet (i.e., 99.97% of particles 0.3 µm in diameter and 99.99% of particles of greater or smaller size).
