Basic principles of Lab Safety Cabinet design: flow of people, logistics, air flow

The purpose of Lab Safety Cabinet is to establish a safe and efficient Lab Safety Cabinet. In the design of laboratory safe cabinets, the factors affecting the efficiency and safety of Lab Safety Cabinets shall be fully considered, such as space, table, storage cabinets, ventilation facilities, lighting, etc. Special Lab Safety Cabinets shall be designed according to national standards.

The design of Lab Safety Cabinet should have reasonable space

In the design of Lab Safety Cabinet, the layout should be determined according to the experimental function module and the needs of the placement equipment, and the rationalization of space should be considered. Meanwhile, the space size of laboratory safe cabinet should be determined from the perspective of development. There are a number of factors that affect the design of laboratory safe space, such as the number of staff, the analysis method and the size of the instrument. Lab Safety Cabinets should be flexible and allow staff to feel comfortable without waste.

The size of the workspace should ensure that the maximum number of staff works at the same time. Effective space should be divided into clean area (office, room, study room), buffer (storage areas, supply area, corridor), pollution area (workspace, washing area, specimen storage area).

Basic principles of Lab Safety Cabinet design:

Flow of people, logistics and airflow; Clean zone, buffer zone and pollution zone.

In the designated experimental area, the number of staff and the number of transport personnel should be controlled. While controlling the safe container access in the laboratory, some preparatory areas should be set up, such as receiving samples or specimens, allowing access to Lab Safety Cabinets and visitors. Transport samples or specimens through staff, automatic transmission, wind systems or other automated systems. The internal communication contact system and the alarm should also be fully considered for notification or alarm (such as disaster, fire alarm, sample arrival, or part of the Lab Safety Cabinet for help). The expansion of the Lab Safety Cabinet space should also be considered, the Lab Safety Cabinet is designed to be extended outward or mobility, in order to meet the Lab Safety Cabinets have the need to expand the future development of space. Transportation and computer network systems are used in Lab Safety Cabinet and Lab Safety Cabinet and the sample or specimen transport and information exchange between the various departments of the laboratory. National laws and regulations, national standards and industry standards, etc.) to a large extent affect the Lab Safety Cabinet design, throughout the Lab Safety Cabinet shall be made by the architect in the design of relevant regulatory requirements.

In front of the space allocation plan, deal with instruments and equipment, staff number, work load, experiment method and other factors make a comprehensive analysis and evaluates the requirements of space standard, and calculate the net area of area and gross floor area. Special functional areas determine their allocation space depending on their function and activity.

Layout design of laboratory safe cabinets

Layout of Lab Safety Cabinet should consider the following: because each Lab Safety Cabinets of the nature of the work, unable to establish a unified laboratory safety ark general design scheme. But principle and flexibility should be taken into account.

1. Transshipment and personnel flow of samples:

To allocate the safe cabinet area of the laboratory, first consider the work flow, the transhipment and transfer of samples, and biosafety factors.

2. Flexibility:

It is extremely important that the design of laboratory safe cabinet can accommodate the future development changes.

3. Safety:

The design and size of the Lab Safety Cabinet should be considered for safety, to meet the building rules of emergency clearance and evacuation exits, and to be equipped with safety equipment for the safety cabinet of laboratories. Emergency wash and shower should be provided within 30 meters of the hazardous chemical reagent. All Lab Safety Cabinets and direct contact with contaminants should be installed in the sink and the sink is located at the exit. The sink should be independent and not mixed with pollutant treatment and experiment.
