Key Points
Millions of Research Articles, Safety Comes First -
As the 2024 New Year begins, we wish everyone a promising future. While the scientific community gears up to make strides in the laboratory, let's take a moment to see if the key safety checkpoints in the laboratory have been cleared together.
Fire Safety
Review
Prevention as Priority, Combining Prevention with Control
NO.1 Fire Emergency Facilities Fully Equipped
Smoke detectors, fire extinguishers, fire blankets, fire sand, fire sprinklers, etc., should be readily available and in normal and effective condition.
The types of fire extinguishers are correctly configured, within their expiry dates (with pressure indicators in normal positions), insurance pins (pull pins) intact, and no damage or corrosion to the body.
NO.2 Emergency Evacuation Routes Clear
Emergency evacuation route maps prominently displayed.
Emergency evacuation routes clear with no obstructions.
NO.3 New Energy Battery Charging
The parking or charging of electric bicycles and other battery-powered vehicles (e.g., hoverboards) poses significant fire safety hazards, therefore charging within the laboratory is prohibited.
Facility Safety
Review
Basic Electrical and Water Safety
NO.1 Electrical Safety
Laboratory power distribution capacity should match, and plugs and sockets should match the power of electrical equipment.
Power sockets securely fixed.
Avoid placing extension cords directly on the ground.
Electrical wires and cables should be free from aging, damage, and have reliable insulation at joints.
NO.2 Reasonable Layout and Normal Operation of Water Supply and Drainage Systems
Sinks, floor drains, and sewers kept clear.
Faucets and pipes free from damage (especially rubber hose joints in cooling and condensing systems).
Emergency Shower and Eye Wash
Review
Emergency Shower and Eye Wash Equipment
NO.1 Emergency Showers and Eye Washes Functional
Main valves are in an open position.
Eye wash water pressure moderate, flow smooth and steady.
Eye wash nozzles free from rust or dirt.
Valves operate smoothly, and water flows freely.
Ventilation System
Review
Ventilation System
NO.1 Ventilation System
Ventilation system operates normally.
Roof fans securely fixed with no loose parts or abnormal noises.
Ventilation hoods equipped with adsorption or treatment devices for toxic gases (such as activated carbon, photocatalytic decomposition, water spray, etc.) operate normally.
NO.2 Reasonable Configuration, Normal Use, and Compliance with Operating Procedures of Ventilation Hoods
Experiments generating toxic or hazardous gases leading to personal exposure must be conducted within ventilation hoods.
Face velocity of ventilation hood maintained at 0.35-0.75 meters/second.
When in use, ventilation hood doors opened to a distance of 10-15 cm from the work surface to maintain ventilation effectiveness and to avoid placing heads inside the hood.
No long-term storage of experimental reagents or waste; no disposable gloves or lightweight plastic bags left in the ventilation hood.
PPE and Emergency Resources
Review
Personal Protective Equipment (PPE)
Personal protective items and emergency resources within their expiry dates and complete.
Wear goggles, masks, gloves, helmets, respirators, or face shields as needed.
Chemical Storage
Review
Laboratory Chemical Storage
Storage rooms, areas, cabinets, etc., should be ventilated, insulated, light-shielded, and safe.
Organic solvent storage areas kept away from heat sources and open flames.
Adequate ventilation for easily leaking or volatile reagents.
No power sockets or extension cords in chemical cabinets.
Chemicals stored in an orderly manner according to classification.
Equipped with necessary secondary leakage protection, absorption, or spill prevention functions; reagents should not be stacked, incompatible chemicals should not be mixed, solid and liquid chemicals should not be placed chaotically, and oxidizing and reducing chemicals should not be mixed; reagent bottles should not be left open.
Chemical reagents should not be stored long-term on laboratory stands without shields.
Abnormal chemical reagent leaks should be dealt with promptly.
Refrigerator Safety
Review
Laboratory Refrigerators
Reagent bottle caps tightened with no open containers.
No food placed in laboratory refrigerators.
Explosion-proof labeling on refrigerator doors if applicable.
Corridor ultra-low temperature refrigerators should be locked.
Sufficient space around refrigerators, no clutter affecting heat dissipation.
Special Equipment Safety
Review
Special Equipment Safety
NO.1 High-Pressure Sterilizers, Dewar Flasks
Safety valves and pressure gauges regularly checked, containers periodically inspected.
NO.2 Lifting Machinery
Before lifting, check the lifting machinery and tools for compliance and reliability to ensure safety.
Strictly follow standard operating procedures.
