CE certification is the EU's product certification. It is the basic safety requirement that products do not endanger the safety of humans, animals and goods, rather than general quality requirements. The coordination directive only stipulates the main requirements, and the general directive requirements are standard tasks. The CE mark is a safety conformity mark rather than a quality conformity mark. It is the "main requirement" that forms the core of the European directive. What is EN certification? EN is a regulation and EN is a standard. Only after passing the EN test can the CE mark be affixed and you can leave the EU. What EN is opened is the product standard. Different products correspond to different EN standards. If a product passes the test of a certain EN standard, it also means that it meets the requirements of CE certification, so it is sometimes called EN certification.   What is the relationship and difference between ce certification and en certification? EN (European Standard): According to the common obligations undertaken by participating countries, the adoption of this EN standard will give legal status to the relevant national standards of a member state, or cancel the relevant standards of an opposing country. In other words, the national standards of member states must be consistent with EN standards. Only products that pass EN's testing standards can obtain CE certification. The difference between en certification and ce certification In simpler language, what is the relationship and difference between ce certification and en certification? CE is a regulation and EN is a standard. Only after passing the EN test can the CE mark be affixed.

Extreme weather such as high temperature and lightning in summer will affect the safety of personnel, equipment and chemicals, and improper response will easily lead to accidents. How to ensure the safe storage of dangerous chemicals in summer, come to understand it. The expansion coefficient of flammable liquid is generally large, stored in a closed container, the volume expands after being heated, and the vapor pressure increases, so that the internal pressure of the container increases, if it exceeds the pressure that the container can withstand, it will cause the container failure or even rupture. The phenomenon of "drum" in the iron drums containing flammable liquids in the high temperature season and the explosion of glass containers are all due to the thermal expansion of the stored liquids. If the container is open, the liquid expands beyond its capacity and spills over. Affected by environmental factors such as temperature and humidity, many dangerous chemicals are easy to decompose after being heated, releasing oxygen or even oxygen atoms, oxidizing other substances, and releasing a large amount of heat. If the ventilation is poor, the heat accumulation does not disperse, resulting in a rise in temperature, it will accelerate the oxidation rate, generate more heat, and promote the temperature to continue to rise, when the temperature reaches the spontaneous combustion point of the substance, it will spontaneously ignite.   ZOYET Outdoor chemical storage container help you solve the problem of storing dangerous chemicals at high temperatures. It used in universities/medical/chemical industry and other fields，Automobile and related enterprises, new energy industry, etc The full series products have CE certificate and Europe explosion-proof certificate(EN 60079).

At present, it is summer, and the safety risk of autocatalytic substances increases sharply under high temperature weather conditions. What are the safety measures for the storage of hazardous chemicals in summer? The hazardous chemical warehouse should use non-thermal refractory materials as the insulation layer of the roof and wall, and the eaves should be appropriately extended to prevent sunlight from entering the warehouse; The wall of the warehouse should be properly thickened, Windows should be opened frequently, indirect ventilation tunnels should be adopted, and double-layer doors and double-layer roofs should be set. Paint window panes blue or choose frosted glass. This one has windproof, rainproof measures, explosion-proof ventilation system.   Hazardous chemicals should be classified, stored in warehouses, parts and racks, and it is strictly prohibited to mix all kinds of articles with conflicting nature, different fire extinguishing methods and easy to cause spontaneous combustion in one place. When storing items, the stack should not be too high, too large, too dense, between the stack and the stack, between the stack and the wall, the column, the roof beam, the lamp should maintain a certain distance, and leave a fire channel, not excess storage. This product partition classification storage, reasonable structure, durable.   A water storage roof or a cooling water pipe is arranged on the warehouse roof to spray water to cool down when the temperature is above 30 ° C, so that the temperature in the warehouse is kept below 28 ° C. Laying stone sacks on the roof of the warehouse can increase the thermal insulation performance of the roof, and can also paint the roof of the warehouse, external walls and window glass white to reduce the absorption of radiant heat and achieve the effect of cooling. According to the nature and packaging of the goods, you can also pour well water and put ice cubes on the warehouse floor, and install air conditioning to cool down if possible. Some warehouses can open Windows in the morning and evening and at night to ventilate, put in cold air, and close doors and Windows at noon to prevent hot air from entering. This product is fully protected and has passed the fire test.   Hazardous chemical warehouses are generally located in the edge of the unit or the city, and maintain a certain distance from other buildings around, so that the warehouse around the formation of an open area, prone to lightning strikes. Therefore, the warehouse should install lightning protection devices to prevent fire accidents caused by lightning strikes. This product meets the requirements of the regulatory authorities, lightning and electrostatic protection system.   The personnel in charge of hazardous chemical warehouses must be trained in safety, pass the examination and be certified to take up their posts. Warehouse management personnel should regularly inspect the warehouse, find problems and solve them in time to ensure safety. This product has hazard identification Settings, electrical identification Settings.

When we are talking about the storage of flammable, combustible and corrosive chemicals, the safety of workplace and warehouse is always the priority. Sometimes our clients got confused about the solution, they do not know if it is safe to store the chemicals indoor, meanwhile the cost of outdoor storage proposal is much higher. The answer is quite straight:Check your volume of storage and follow the local regulation. Of course there are safety risks like fires, explosions, besides it the deviation against the local regulation would lead to large penalties charged by government, in order to follow the regulations, you would have to store your chemicals in approved containers, cabinets or lockers.   First let us take a review of the regulation: The chemical storage regulations are based on the danger level of chemical. The NFPA and OSHA defined the grade of chemicals by their physical and chemical characteristics. The chemical with higher grade would take greater restrictions on usage and storage. Small volumes do not need outdoor storage, according to OSHA 1910.106(e)(2)(ii)[b], the limit of liquids for storage would be: Category 1: 25 gallons Category 2,3 or 4: 120 gallons Category 2,3 or 4 in single portable tank: 660 gallons   To hold strong chemicals indoor there are specified cabinets to be used: Flammable chemical storage cabinets are designed to provide heat resistance and protect chemicals inside from fires. The air gap between walls would insulate fire and the self latching device would make sure the cabinet is closed when fire starts out. Those cabinets are located in work places, nearby the location of usage and hold enough chemical supplies for daily use. But, there are volume limits according to the local regulation. About the local regulation, please always remember: it is differently specified about the chemical category, volume of storage between cities, states and countries   Let us take one example here, for facilities like school, labs, small sized companies or work place, the total volume of chemical storage is requested not to exceed the limit: .   Please pay attention to the numbers shown in the table above, it is taken from the local regulation of Beijing, China, which means in the capital city of China, it is the limit of your chemical storage, no matter it is indoor or outdoor. And for the limit of MAQ (maximum allowable quantities) of chemicals to stay indoor, it might be differ per local fire codes and regulations.So the most important thing is to consult Bureau of Safety Supervision (or Authority having_jurisdiction) for final determination of your storage. When storing margin quantities of flammable, combustible or corrosive chemicals, the MAQ would limit the volume of chemical to stay indoor, but cost of new building is always high, not even mention the limit of boundary, construction plan, etc. And that is why our customers choose to buy outdoor storage container, it is anti explosive, fire resist and comply with the local regulations. It saves your time, money and also gets you less trouble. Customization is valid for different needs and budgets. Indoor or outdoor, it is not only an option, we need to maximum the storage volume and fit in the local regulations, if you have questions about it still, you are always welcomed to contact us through mail at info@huanawell.com.

Today we are going to talk about some pictograms, those are used on labels to alert chemical users hazards that they may be exposed. The hazard pictograms consist of a symbol on white background within red boarder and represents a distinct hazard. The hazard pictograms are from the international Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Hereon we would list some commons related to our industry regarding to physical and health: Explosive (Symbol: exploding bomb)   Unstable explosives Explosives, divisions 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 Self-reactive substances and mixtures, types A, B Organic peroxides, types A, B Flammable (Symbol: flame)   Flammable gases, category 1 Flammable aerosols, categories 1, 2 Flammable liquids, categories 1, 2, 3, 4 Flammable solids, categories 1, 2 Self-reactive substances and mixtures, types B, C, D, E, F Pyrophoric liquids, category 1 Pyrophoric solids, category 1 Combustible solids, category 3 Combustible liquids, category 3 Self-heating substances and mixtures, categories 1, 2 Substances and mixtures, which in contact with water, emit flammable gases, categories 1, 2, 3 Organic peroxides, types B, C, D, E, F Oxidising(Symbol: flame over circle)   Oxidizing gases, category 1 Oxidizing liquids, categories 1, 2, 3 Oxidizing solids, categories 1, 2, 3 Corrosive(Symbol: Corrosion)   Explosives, divisions 1.5, 1.6 Flammable gases, category 2 Self-reactive substances and mixtures, type G (see HAZMAT Class 4 Flammable solids） Organic peroxides, type G Skin corrosion, categories 1A, 1B, 1C Serious eye damage, category 1 Acute toxicity (Symbol: Skull and crossbones) Acute toxicity (oral, dermal, inhalation), categories 1, 2, 3 Hazardous to the environment(Symbol: Dead tree and fish)   Acute hazards to the aquatic environment, category 1 Chronic hazards to the aquatic environment, categories 1, 2 Environmental toxicity, categories 1, 2   Hazard pictograms are one part of the labeling of containers, those are widely used in different industries. To us, we always use some of them on the labeling of our products, just to inform our clients and users about the type of material that storing in our products: Take our most common product line of safety cabinet as an example, here we can see the labeling of this cabinet is using the sign of flammable, which means the liquid with flash point temperature between 0 and 140°F (60 °C). And depends on the complex chemical characteristics of different material, additional config like ventilation or fire extinguishing system would be needed for fire hazard. And according to the EN standard, the cabinet is painted in yellow. And for this cabinet we can tell from the label that the chemical stored inside is corrosive when referring to the effect of living tissues. It can be poison, cause chemical burn and distinct damage, even rusting to metal. Some type of corrosion creates corrosive mists when contacting air. Sc depends on the chemical, we have solutions like PP tray, PP lining, ventilation system to reduce the hazard of corrosion. According to the standard, the cabinet color is blue. For narcotic storage cabinet, we use toxic symbol on our labeling, which shows the material inside would be harmful to living health, the control of this kind of material would be extremely strict, so usually the lock system is updated and normally calls for two operators. And depends on the toxic chemicals inside, different systems are available, too. According to the standard, the cabinet color is light gray.   For any industries, working areas or products involved with those hazard pictograms, people working around need to pay special attention to them, and when there is hazard around you in your working area, you need to learn some basic knowledge to protect yourself for your own safety. that is the basic of working safe and healthy.

Storage arrangements for commonly used dangerous goods depend on the classification, breakdown, container type, storage method and fire protection requirements of dangerous chemicals. According to the performance of dangerous goods partition, classification, sub-storage. All kinds of dangerous goods shall not be stored together with contraindicated materials. According to Article 26 of the Regulations on the Safety Management of Hazardous Chemicals, the special warehouse for hazardous chemicals shall meet the requirements of national standards and industry standards, and set up obvious signs. The special warehouses for storing highly toxic chemicals and dangerous chemicals that are easy to make explosions shall set up corresponding technical prevention facilities in accordance with the relevant provisions of the State. (GB 15603--1995) specifies that the stored hazardous chemicals should be clearly marked, and the marking should comply with the provisions of GB 13690--1992. When two or more hazardous chemicals of different grades are stored in the same area, the performance mark of the highest grade hazardous goods should be followed.           Clearly and intuitively indicate the physical and chemical properties of dangerous goods and the degree of danger. Remind users to pay attention to the relevant points in the process of transportation, storage and use! Be safe!

Laboratory identification is an indispensable element to ensure laboratory safety, which can ensure that all types of personnel can easily, quickly and accurately understand the overall layout of the laboratory, various regional environments, laboratory functions and risk levels, equipment use status and precautions, etc., so that the management and use of the laboratory is more scientific and efficient. However, some laboratories still have unclear safety signs, incomplete coverage, and do not know how to post, so this issue is organized for this part of the content, hoping to help.   WARING Graphics designed to remind people of their surroundings and dangers occurring in Barcelona.

Dangerous chemicals are used in different degrees in the production process of pharmaceutical enterprises. In pharmaceutical companies, many of the raw and auxiliary materials used in drug production are hazardous chemicals (such as methanol, ethanol, acetone, concentrated hydrochloric acid, etc.), which are flammable, explosive and corrosive. And the production process usually requires complex processes such as heating, cooling, and pressurization, which determines that there are many dangerous and harmful factors in the entire production process. Therefore, accidents such as fire, explosion, scalding, poisoning, suffocation, and mechanical injury usually occur.
