China Wuxi Huanawell Metal Manufacturing Co.,Ltd. Company News

During laboratory safety inspections, storage rooms for easily explosive chemicals and temporary storage rooms for hazardous chemicals are always of paramount importance. Many clients have reported: "We know explosion-proof is necessary, but which specific equipment needs to meet the standards? What regulations should we refer to?" As a service provider with years of experience in laboratory safety, ZOYET, combining national, industry, and group standards, has clarified the electrical and ventilation explosion-proof requirements for these hazardous areas—not just "explosion-proof," but also "compliant implementation." Whether designing a new laboratory or upgrading an existing facility for safety, the following three standards are the core guidelines. T/CCSAS 005-2019（T/CCSAS 011-2021）： 1. First, determine the "hazard level": If the temporary storage room belongs to Zone 0-2 of explosive gas atmosphere (e.g., storing flammable gases) or Zone 20-22 of explosive dust atmosphere (e.g., certain easily explosive dusts), all electrical equipment, from fume hoods and lighting fixtures to electrical instruments, must be matched with the corresponding explosion-proof rating. 2. "Default requirements" for storing flammable materials: Rooms dedicated to storing flammable liquids/gases must, unless professionally assessed and verified, be equipped with explosion-proof electrical equipment at least according to Zone 2 gas hazard zones; simplification is not permitted. 3. Additional reminders: Anti-static measures (e.g., anti-static flooring, anti-static clothing for operators) must be provided simultaneously. Open flame heating and electric furnaces are prohibited. Explosion-proof refrigerators must be used when storing low flash point chemicals. SH/T 3103-2019： 1.Fans & Ducts: For areas where hazardous chemicals are temporarily stored, such as reagent rooms and sample storage rooms, the exhaust system must use explosion-proof fans, and the ducts must be made of metal (to avoid the risk of static electricity buildup). 2.Electrical Details: All switches, sockets, and light fixtures in the rooms must be explosion-proof. Where electrical wiring passes through partitions, it must be isolated and sealed (to prevent the spread of flammable gases through gaps in the wiring). GB 51283-2020： Ventilation system: If the exhaust air from the temporary storage room/laboratory may contain flammable and explosive substances, explosion-proof fans and motors should be selected as the preferred type to eliminate the risk of sparks during the exhaust process.   We have found that many laboratories do not neglect explosion protection, but rather tend to have problems with the "details": 1. Replacing only the fan without replacing the switch – assuming that installing an explosion-proof fan is sufficient, neglecting small components such as sockets and lighting fixtures. In reality, any non-explosion-proof electrical equipment can become an ignition source.   2. Skipping the "hazard level assessment" – directly selecting equipment based on the lowest standard without determining the specific explosion-proof level according to the type of stored chemicals (gas/liquid/dust), resulting in a mismatch between equipment and risk. 3. Neglecting supporting measures – failing to implement "auxiliary requirements" such as anti-static measures and wiring sealing significantly reduces the effectiveness of the explosion-proof equipment.   To address these issues, ZOYET's solutions consistently revolve around "full-chain compliance": from the initial hazardous area delineation and equipment selection guidance, to the mid-term installation and acceptance, and finally to the later regular inspections and maintenance, ensuring that every step complies with regulations. 1. Customized Risk Assessment: Based on the types of chemicals stored and the layout of temporary storage rooms, accurately determine the explosion hazard level of the area, avoiding "over-explosion protection waste" or "inadequate standards leaving hidden dangers"; 2. Equipment Selection Consulting Service: Provide a selection list and compliance basis for explosion-proof electrical equipment and fans, assisting companies in selecting products that meet standards (avoiding the purchase of "pseudo-explosion-proof" equipment); 3. Full-Process Acceptance Control: After equipment installation, conduct item-by-item inspections against specifications, including details such as electrical sealing and anti-static measures, ensuring first-time acceptance; 4. Regular Safety Inspections: Provide periodic inspections according to the company's needs, promptly identifying problems such as aging explosion-proof equipment and ineffective wiring seals, and eliminating risks in advance.

Container transportation speeds up the flow of goods, reduces circulation costs, saves labor consumption in logistics, and completes the transportation production process quickly, with low consumption, high efficiency and high benefits, and delivers the goods to the destination to the consignee. It is a high-efficiency, high-benefit and high-quality transportation mode. Special container transportation has become an indispensable part of international container transportation due to its own characteristics.   What is a special container?   A special container is a container that is specially designed and equipped in terms of structure and equipment to meet the needs of special cargo transportation.   What are the types of special containers?   There are many types of containers due to the different types of goods they are suitable for, and the main types are as follows:   FLAT RACK CONTAINER:   This is a container without a top and wall, and the end wall can also be removed, leaving only the bottom and four corner columns to bear the cargo. If the four corner columns are removed, it can also be used as a platform container. This type of container is mainly used for long and large items, overweight items, light and bulky goods, heavy machinery, steel, steel pipes, bare equipment, etc. that are not suitable for loading into general cargo containers or open-top containers, and will produce concentrated loads. Heavy goods, oversized goods, goods that are not afraid of wind and rain, goods that need to be loaded from the top or side of the box, and goods that need to be fixed in the box.   OPEN TOP CONTAINER:   This is a container without a top or with an open top. When loading and unloading goods, a crane is needed to load or unload heavy goods from the top. After loading the goods, the top is covered with a waterproof tarpaulin to prevent damage to the goods. This special container is suitable for loading extra-high goods such as glass plates, steel products, plywood, mechanical equipment, heavy goods that can be fixed by the side walls, and goods that are difficult to load and unload from the door and must be loaded and unloaded from the top of the box.

Advantage 1: Plate structure, saving transportation and storage space   A single standard special container can form a box-type house with a standard 20-foot container space, which can be packaged into a package with 1/4 volume of a standard 20-foot container. Four such packages are packed together, which is equivalent to the volume of a 20-foot container. It can be directly used for sea and land transportation, which is sturdy and convenient, and greatly saves space during transportation and warehousing, thereby reducing transportation and warehousing costs.   Advantage 2: Factory pre-assembly, minimizing the workload on site   The bottom frame and top frame of the standard box, including the decorative layer, are completed in the factory, and the circuit pre-embedded is also completed in the factory. On site, you only need to fix the columns and wall panels to the bottom and top frames with bolts, insert the wire clips in sequence, and then nail the decorative profiles to the corresponding positions, and an 18-square-meter house is completed. This reduces the workload on site to a minimum.   Advantage 3: Glass wool as thermal insulation material, good fireproof performance   The bottom frame and top frame are made of 100mm thick glass wool, which has excellent thermal insulation and fireproof performance. The wall is made of high-density glass wool with a bulk density of 64kg. This new material not only has high strength and good thermal insulation performance, but also has good fire resistance and flame retardancy, reaching A1 level.   Advantage 4: Strong structure, can withstand earthquakes and typhoons   The size of the structural parts is customized according to the shipping container, which greatly exceeds the size of the components of ordinary steel structure houses. Through the connection of high-strength bolts, a high-strength overall structure is formed, which can withstand earthquakes and typhoons.   Advantage 5: High comfort   Wall panels: 75mm thick glass wool (a good thermal insulation material), with high density standards   Advantage 6: Modular design, unlimited connection and expansion   The modular house can be connected vertically in 3 layers/infinitely horizontally; the overall surface of the house can be adjusted during the use of the project   Advantage 7: Standardization, easy to repair and maintain   Since the special container house adopts modular design, if it is damaged, it can be replaced with standard parts, from the top frame and bottom frame to a wall panel, which is conducive to repair and maintenance.   Advantage 8: Short delivery time   Product prefabrication: production and on-site preparation work are carried out at the same time   Easy installation   Advantage 9: Improve corporate image and recognition   A safe, beautiful and comfortable space will be recognized by your customers, management and users.

Container modular house is a new type of house. It is small in size but has a long service life and is cheap. It is suitable for scenic spots and large construction sites. At present, the technological investment in container modular houses is gradually increasing, so the living experience is getting better and better. It can meet all the requirements of living. So what are the precautions when purchasing container modular houses?   First, pay attention to whether the weak current lines are complete and safe. When purchasing a container modular house with quality assurance, pay attention to the weak current lines. Because the container is small in area and the weak current lines are relatively concentrated, the scientific design of the weak current lines should be considered first, and at the same time, pay attention to whether its lines are complete. In order to better meet the needs of living, network cables, electrical wires and socket cables should be reserved in advance.   Second, pay attention to the load-bearing capacity of the ground material. Since there is no load-bearing wall support in the middle of the most commonly used container modular house, all its load-bearing capacity depends on the ground, which requires the ground material to have strong compression resistance and large load-bearing capacity. In order to have a better living experience, you can choose solid wood or PVC flooring for a better foot feel.   Third, pay attention to whether the overall thermal insulation meets the requirements. Due to the spatial structure of the container module room, air conditioning temperature control methods are often used for cooling and body temperature, which requires the container module room to have good thermal insulation properties. Therefore, when purchasing, you must pay attention to whether the sealing of the container module room is intact and whether the overall thermal insulation can meet the requirements. Generally speaking, EPS foam board should be used for insulation inside.   Fourth, pay attention to whether the outdoor spray paint material is anti-corrosion. In order to better ensure the external gloss of the container module room and prevent the external paint from cracking due to excessive ultraviolet rays, which affects the appearance, when choosing, you should focus on whether the outdoor spray paint can have anti-corrosion effects and whether it has anti-ultraviolet effects. Generally, ordinary paint is not used on the exterior of the container, and special paint is often used.
