Question: There are many different brands of fume hoods available on the market; how can one choose the right one? Answer: The following factors should be taken into consideration, such as storage conditions and compatibility issues with different chemicals ； Type of container stored ； Capacity is needed ； Compliance and regulatory requirements ； Independent third-party testing ； Door closure style and handling style preferences ； Quality and fire safety factors, longevity and warranty ； Easy to use (such as easy access, self-locking doors, and hidden automatic door locks). Question: Why are anti-static wires connected to the bottom of the safety cabinet? What is its function? Answer: Simply put, connecting to an electrostatic ground wire is intended to eliminate static electricity, thereby preventing fires and explosions caused by static sparks in flammable liquids. More specifically: In accordance with relevant standards, equipment and pipelines in areas prone to explosions and fires that may generate static electricity must be equipped with static grounding measures. Storage facilities for combustible gases, liquefied hydrocarbons, combustible liquids, and combustible solids should also have static grounding systems. The accumulation of static charge on containers holding flammable liquids as well as on the human body can lead to static sparks, and such sparks can cause the flammable liquids to explode during their storage, transportation, or distribution. Therefore, in accordance with OSHA’s standards and safety practices for flammable liquids, during the transfer of flammable liquids from oil drums to containers, as well as in the safety cabinets used to store such liquids, it is necessary to connect the existing grounding devices to the oil drums and safety cabinets using anti-static grounding wires, so as to conduct static electricity into the ground and prevent fire accidents caused by static sparks. Question: How to use the cover of the exhaust vent on a chemical safety cabinet properly? During normal use of the safety storage cabinet, the ventilation hole covers provided for fire and explosion protection must be tightened to keep the cabinet sealed. However, depending on the volatility of the chemicals stored, the ventilation openings should be opened regularly to allow for proper ventilation, so that the volatile gases from the chemicals can be removed effectively and promptly. This helps to protect the safety of employees and also prevents explosion hazards caused by high concentrations of these volatile gases. After regular exhaust ventilation, please re-tighten the vent cover. Question: What is the importance of the safety cabinet door lock? Answer: YES. This is very important, as a slightly ajar safety cabinet can expose flammable liquids, leading to potential fires that are hard to prevent. A door locking system at 3 o’clock is necessary. Additional note: OSHA (Occupational Safety and Health Administration regulations) 1910.106(d)(3)(ii) stipulates that the door locks of fire cabinets must be equipped with a three-point interlocking self-locking mechanism. And a management system with two people and two locks is required! Self-locking mechanical device—a three-point linkage system. All safety cabinets are equipped with a stainless steel, three-point bullet-type self-locking system that provides a simple and reliable door closer with enhanced heat resistance. Even without a rotating handle, the door can be ensured to stay completely closed, providing a certain level of safety protection against potential fires. It comes with two keys, allowing for secondary key management of the cabinet. From a distance, it is possible to clearly see whether the door is locked. The built-in handle does not obstruct the passage and prevents accidental entanglement with passing objects. The safety cabinet is also equipped with a fuse that keeps the door open while in use; in the event of a fire, when the temperature reaches 74 degrees Celsius, the fuse melts and the door closes automatically.
