What are the precautions need to be taken while working under the laminar airflow?
Precautions
- The laminar flow cabinet should be sterilized with the UV light before and after the operation.
- The UV light and airflow should not be used at the same time.
- No operations should be carried out when the UV light is switched on.
- The operator should be dressed in lab coats and long gloves.
What are some important points to remember in cleaning the laminar flow hood prior to aseptic procedure?
Cleaning Tips
- A new cloth should be used for each wall.
- Always clean from back to front, top to bottom.
- Overlap each swipe.
- Do Not attempt to clean the filter. Filters should be replaced every 3-5 years.
How do you maintain laminar flow?
Clean the ceiling of the unit first. Clean the back wall (of a vertical laminar flow hood) next, going from top to bottom. Clean the sides (swiping from top to bottom in overlapping lines). The work surface should be the last surface cleaned, beginning in the back and ending at the front of the unit.
How can you avoid cross contamination in a laminar flow hood?
Laminar flow cabinets are commonly used in places where contamination is a concern, like a biology laboratory, so you will need to be careful of contamination by yourself and laboratory air. To prevent contamination, use ethanol to sterilize gloves and any equipment before using the cabinet or opening the sash.
Which precautions can you take to minimize disruption of cabinet airflow patterns?
Move arms in and out of the cabinet slowly, perpendicular to the face opening, to limit disruption of the protective air flow patterns. Manipulation of materials inside the cabinet should be delayed for 1 minute after placing hands/arms inside the cabinet to allow the air to stabilize and to “air sweep” arms.
What is use of laminar air flow?
Laminar air flow systems are used in various applications such as life science research, mushroom cultivation, microbiology, IVF, IUI and histopathology / pathology lab, plant tissue and cell culture and pharmaceutical and electronics industry and many more.
When working in a sterile hood one must?
While working in the hood, perform all work at least 4 in. back from the front opening, and avoid rapid movements that might disrupt the laminar air flow. Avoid moving materials or hands in and out of the cabinet as much as possible.
Which solution is recommended for cleaning a laminar flow hood?
Clean all flat surfaces of the hood with 70% isopropyl alcohol, or other antibacterial scrub such as benzalkonium chloride solution, working from top to bottom, then from back to front.

How do you clean a laminar airflow?
Start by spraying a clean wipe and wiping the ceiling of the flow hood, taking care to disinfect and wipe hard-to-reach sections. Take a fresh side of the wipe or a new one. Continue with the sidewalls and then the work surface using right-to-left, back and forth movements that overlap by 50%.
How can we protect media plates from contamination?
1) Avoid repeatedly taking things in and out. Keep your media capped when not in use. 2) Never obstruct the air flow. Place your instruments in the centre, with at least 2inches away from any wall of the cabinet.
Which of the following precautions is required when working in a biological safety cabinet?
Take precautions during work: Turn off UV lamps while the lab is occupied. The stainless steel interior of the BSC can reflect potentially hazardous illumination out of the opening of the cabinet. Never have the UV lamp on while an operator is working in the cabinet.
What are the safety precautions when working in a biosafety cabinet?
Minimize movement (especially rapid movements) into and out of the BSC, or in areas near the BSC. Do not block the front grill or rear vents with your arms or other materials. Work at least 4 inches from the inside edge of the front vent. Bunsen burners, other continuous flame devices, or flammable gases are prohibited in biosafety cabinets.
What is a laminar flow hood used for?
Laminar flow hoods are often used to work with biological samples, semiconductors or other sensitive materials. According to the CDC , the laminar air flow principle was first developed in the early 1960s.
What is laminar flow in a clean bench?
In a horizontal clean bench, laminar air is projected horizontally towards the operator. In both instances, laminar flow provides a particulate-free work area. (Note that some categories of laboratory equipment, like Class I enclosures with perforated baffles or certain high performance fume hoods, employ laminar-like flow.
Can cell culture be done on a laminar flow bench?
Although cell culture can theoretically be carried out on an open bench in a low-traffic area, most cell culture work is carried out using a horizontal laminar-flow clean bench (see Basic Protocol 2) or a vertical laminar-flow biosafety cabinet (see Alternate Protocol).
