Laboratory decorationIt is necessary to consider safety, functionality, compliance, and long-term usage requirements, involving multiple aspects such as design, materials, construction, and acceptance. The following are detailed precautions for laboratory decoration, sorted by key stages:

1、 Pre planning and design phase

Clearly define the laboratory type and functional zoning

Classified by disciplines: Chemistry, Biology, Physics, Cleanroom and other laboratory requirements vary greatly. For example, chemical laboratories require independent ventilation systems, biological laboratories require biosafety cabinets and independent sewage discharge, and clean rooms require strict dust control.

Divided by risk level: high-risk areas (such as pathogenic microorganism operations) are strictly isolated from low-risk areas (such as office areas) to avoid cross contamination.

Reserve expansion space: Consider future equipment upgrades or functional extensions, and plan pipeline embeddings and spatial layouts in advance.

review of compliance

National standards: comply with the "General Requirements for Laboratory Biosafety" (GB 19489), "Code for Design of Cleanrooms" (GB 50073), etc.

Industry standards: Medical laboratories must comply with the "Management Measures for Clinical Laboratories in Medical Institutions", and chemical laboratories must meet the requirements of environmental protection departments for the discharge of waste gas and wastewater.

Approval process: Handle fire inspection, environmental protection approval, biosafety filing and other procedures in advance to avoid later rectification.

Humanization and Efficiency Design

Flow line optimization: The layout of the experimental platform, fume hood, and instrument equipment conforms to the operating procedures, reducing the walking distance of personnel.

Safety facilities: Emergency eye wash stations, sprinkler systems, fire extinguishers, etc. must be accessible within 10 seconds, and escape routes must be clearly marked.

Comfort: Reasonable design of lighting (avoiding glare), noise control (such as equipment soundproof covers), temperature and humidity regulation (such as independent air conditioning in precision instrument areas).

2、 Material and equipment selection

Corrosion resistant and easy to clean materials

Ground: Epoxy resin self leveling (acid and alkali resistant, anti slip), PVC roll material (seamless splicing, leak proof).

Wall: Color steel plate (fireproof, easy to clean), ceramic tiles (chemical resistant), anti-corrosion coating (such as epoxy resin paint).

Tabletop: Solid core physical and chemical board (chemical laboratory), stainless steel (biological laboratory), anti-static material (electronic laboratory).

Fire and explosion prevention design

Material fire rating: Class A non combustible materials (such as rock wool board) are used for walls and ceilings, and the ground fire rating is ≥ B1.

Explosion proof electrical appliances: Explosion proof lamps, switches, and sockets should be used in flammable and explosive areas (such as gas storage rooms).

Explosion proof doors and windows: using explosion-proof windows or blast resistant doors, equipped with gas leakage alarm and automatic exhaust system.

Ventilation and air conditioning system

Ventilation cabinet: Select full exhaust or supplementary air according to the type of experiment, and control the surface wind speed at 0.4-0.6m/s to ensure that harmful gases do not leak out.

Air conditioning system: The clean laboratory adopts laminar flow design (hundred level/thousand level/ten thousand level), with temperature and humidity accuracy of ± 1 ℃/± 5% RH; ordinary laboratories control temperature and humidity within a comfortable range (20-26 ℃, 40-60% RH).

Air filtration: Biosafety laboratories require high-efficiency particulate air (HEPA) filters, while chemical laboratories require activated carbon adsorption devices.

Water, electricity, and gas pipelines

Water and electricity separation: Strong electricity (220V/380V) and weak electricity (network, signal) are laid in separate slots to avoid interference.

Gas pipeline: Seamless steel pipes are used for high-pressure gases (such as nitrogen and argon), and flashback arresters are installed for flammable gases (such as hydrogen).

Emergency shutdown: The laboratory's main power supply and gas main valve are equipped with emergency shutdown devices that can be remotely controlled.

3、 Construction and acceptance stage

Construction safety and quality control

Fire isolation: The construction area is completely isolated from the operating laboratory, and hot work requires approval and equipped with fire extinguishing equipment.

Concealed engineering acceptance: Conduct pressure testing and leak detection after laying water, electricity, and gas pipelines, and take photos for retention.

Dust prevention measures: Clean room construction requires wearing dust-proof clothing, using dust-free tools, and thorough cleaning after construction.

Equipment installation and debugging

Ventilation system: Test the wind speed and exhaust volume of the ventilation cabinet to ensure compliance with design requirements (such as ≥ 15 air changes per hour in the chemical laboratory).

Gas pipeline: detect gas purity, pressure stability, mark pipeline flow direction and gas name.

Instrument grounding: Precision instruments (such as scales and microscopes) need to be independently grounded to avoid electrostatic interference.

Acceptance criteria and documents

Functional testing: Simulate the experimental process and check whether ventilation, water and electricity, and gas supply are normal.

Compliance documents: Provide fire inspection reports, environmental testing reports, equipment qualification certificates, etc.

Training handover: Train laboratory personnel on equipment operation, safety regulations, and emergency response procedures.

4、 Post maintenance and upgrade

Regular inspection: Check the status of equipment such as fume hoods, fire extinguishers, gas alarms, etc. every quarter.

Cleaning and maintenance: The floor and countertop are cleaned daily, and the ventilation system's filter screen is cleaned annually.

Function upgrade: Adjust the layout or add equipment according to experimental needs, and plan pipeline renovation in advance.

Laboratory decorationCommon Misconceptions and Solutions

Misconception 1: Neglecting the importance of ventilation systems can lead to the retention of harmful gases.

Solution: Choose a professional ventilation design based on the type of experiment to avoid a one size fits all approach.

Misconception 2: Choosing inferior materials to save money and frequent maintenance in the later stage.

Solution: Prioritize the use of materials that are corrosion-resistant and have a high fire rating, resulting in lower long-term costs.

Misconception 3: Neglecting personnel operating habits leads to low efficiency.

Solution: Invite experimental personnel to participate in the design phase, optimize the flow line and equipment layout.

Through systematic planning, strict material selection, standardized construction, and scientific acceptance, the laboratory can ensure safe and efficient operation, while reducing maintenance costs in the later stage.
