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. " In the synthesis of chemical raw materials, the chlorination process, oxidation process, sulfonation process, hydrogenation process, etc. are key regulatory processes, and the ethyl acetate, methanol, toluene, ethylene oxide, etc. used are key regulatory hazardous chemicals.   ZOYET provides security solutions for the storage of hazardous chemicals in the pharmaceutical industry： Outdoor chemical storage container Obtained EU CE certification and EU explosion-proof certification, providing professional solutions for outdoor hazardous chemical storage.

Last time we discussed about the ethanol and its solution for storage. Today we are going to discuss about its brother: Ether. Ether is widely used in health care industry and well known as antiseptic to prevent infection when an injection is made, also it is used as an anaesthetic in hospitals to help people go to sleep or become unconscious during surgery. Ether is created from the chemical action between ethanol and sulfuric acid, so its physical and chemical characteristic is close to ethanol: it is highly flammable, volatile, easily to form explosive peroxides. In fact it is so easy to form peroxide that any exposure to light and air would enhance the formation, which makes this chemical extremely dangerous with prolonged storage. No matter Ethyl ether, isopropyl ether, tetrahydrofuran or many other ethers tend to absorb and react with oxygen from the air to form unstable peroxides that may concentrated by evaporation or distillation, and when combined with other compounds that give a detonatable mixture, or when disturbed by unusual heat, shock, or friction, the whole thing would become extreme violence. That is how we get unexpected explosions. Ether would ignite at temperature at or above 160 C (320 F). The vapor forms explosive mixtures in air at concentration of 1.9-36% by volume. The flash point of ethyl ether is -45 C (-49 F). Though there is no evidence show refrigerated storage prevent formation of peroxides, but it is frequently stored under refrigeration. So, when we are storing ether, keep the containers sealed, DO NOT expose your ether in air for long, no matter it is glass made bottle or outdoor steel tanks. Good ventilation would be needed to make sure the vapors got no way to mix with air and create explosive mixtures with other compounds. Make your room temperature below 26 C, it should be cool. DO NOT store ether with Oxidant, DO NOT store big amount of ether, and DO NOT expose it to source of heat and ignition. When your ether has not been opened for long time, it is better not open it without protection. Also, make sure the containers for ether are kept with spill containment solutions. How we ZOYET would do this? First you need a qualified cabinet to make sure you and your chemical stay safe. A special made storage cabinet for chemical, fire proofed comply with EN-14470-1 would be ready for you. Meanwhile we would prepare PP tray for your ether containers just in case there is leakage. Then you need ventilation system connected to the cabinet, it includes extraction fan and filtration system to make sure the vapors would be extracted out to the atmosphere, in clean condition complied with NFPA and your local regulation of environmental protection. For large amount of ether, store them outside your building, keep a distance of 15 meters. Our explosion proof outdoor container would be perfect choice for you to keep your ether in stable condition. It has temperature control, ventilation, ex-proof electrical system, and most importantly the pressure relief structure to make you safe when explosion actually happens. It is weather proof, fire proof and explosion proof, capable of all kinds of customization you like. And if you need further technical support from us, please do not be hesitate to contact us!

Over the summer months, people relax and enjoy the days, but please remember to act your responsibility, stay alert to danger and take fire safety precautions. During this summer, there were several fire accidents happened to the shop retails in several cities and caused heavy loss of lives and fortune. Fire started of different reasons, source of ignition, fuel or oxygen exposed to heat source, stock of highly flammable goods, old wiring electrical system, poor maintenance of fire distinguisher, etc. All those tragedies remind us one thing: danger is not that far away from us, and fire risk assessment is quite necessary. Fire hazard, like kitchen areas, catering/hospitality facilities, operation area for electrical equipment, power distribution room, waste treatment area, etc. For fire risk assessment, you can find specialist to provide you professional evaluation service, meanwhile there are several points you can also check by yourself: 1. Please regularly (monAround your household, your working area, your shop, pay attention to areas that present thly, yearly) check your electrical system and test it, rectify issues you find immediately. 2. Please keep your electrical items well maintained, test, repair or replace them when they are not vital. 3. For heating device or cooling device with big power, check for overload situation of those devices, make sure there will not be short-circuit issues. 4. Set up emergency plan to determine what to do when fire starts out. 5. Take safety training at your work place. 6. Do not mix up the material in your storage area, especially for categories of fuel, chemical and gas. 7. Pay special attention to the waste treatment, do not accumulate dangerous waste around your property, no matter inside or outside, dispose them properly in certain period. Good housekeeping is advisable generally. 8. Ensure fire evacuation routes are clear all the time, do not stock rubbish. 9. Use fire carefully, and do not leave fire on when you are not around. 10. Check out fire source nearby when you are making a stock. 11. Set up fire alarming system and fire distinguishing sprinkler system. 12. If your space is divided into several zones, please consider to use fire proof access, those doors can stop fire for a while when fire accident actually happens.   And as a supplier, what can we do for you? In order to avoid exposed your flammable waste to source of ignition, the normal solution is to seal the fire and cut off the air supply, which calls for proper waste treatment. Hereon we provide you our product—ZOYET safety storage cabinet.Easily identify, organize and segregate liquids by using the correct color cabinets.

When we talk about Acetone, one interesting fact about it is: if we pour acetone on top of small amount of water SLOWLY, we would see two layers forming, and the acetone layer is on top. That means two things: 1.Acetone does not mix with water. 2.Acetone is less dense than water. So, this makes acetone used as organic solvent in industries, manufacturing and pharmaceuticals, it makes great degreaser, cleaner, remover, thinning agent, etc and it helps to be used as a solvent to deliver accurate dosage in medication. But according to NFPA, acetone is defined as class 1B flammable liquid, which means it is extremely flammable and dangerous. The flash point of acetone is -20 C (-4 F). Furthermore, when acetone forms vapors and mix with air, the mixture of 2.5-12.8% would be explosive when get touched with source of ignition. Static discharge may also ignite acetone vapors (for the hazard of static discharge, please refer to our historical article), the sensitivity to source of ignition makes acetone hard to store. For indoor storage, no more than 60 gallons of acetone can be stored, and if you need to store more than 120 gallons of acetone, special safety building for flammable storage would be needed. And the fire rate of the building should be 2 hours/4 hours. And when working with acetone, you need to wear PPE, in order to protect your eyes and skin away from touching acetone. Firstly do not store large amount indoor, you need to use LDPE bottle with good sealing to put in your acetone, then put your bottles into delicate safety cabinet for flammable storage. Keep your warehouse well vented and free of ignition, no fire work around, no smoking. Do not mix the storage with oxidizing agents/alkalines. Do not let room temperature go up to more than 26℃. And for large amount storage of acetone, it would be better to use our outdoor storage container, it would be comply with NFPA regulation and safe enough against fire and explosion.  

Why the acetylene cylinder must be kept upright? 1.When the acetylene cylinder which contains filler and solvent (acetone) and lays on the floor for usage, the acetone is easily flow out with acetylene gas, this would increase the consumption volume of acetone and reduce the burning temperature, and in any case backfire occurs it might cause explosion of acetylene cylinder. 2.When the acetylene cylinder is laid on the floor, it is easy to roll, and when it hits another cylinder or something, the collision might cause accident. 3.The acetylene cylinder equips with anti-vibration ring, the purpose is to avoid collision of cylinders during unloading, transportation and usage, the ring is made of rubber and it is electrical insulator, when the cylinder is laid on the floor it is same as laying on insulator, the static generated on the cylinder can not spread to ground and produce static sparks. And when acetylene gas leaks, it would be easily cause combustion and explosion accidents. 4.When in use, the acetylene cylinder equips with regulator and fire arrestor connected with a hose, and if the cylinder is laid on the floor, it might break the regulator easily or pull the arrestor off the hose, and that will cause acetylene leakage, or even combustion and explosion, based on the reasons above, the acetylene cylinder must be placed upright. Why excess pressure must be reserved in the acetylene cylinder? As the explosion limit of acetylene is quite low, even a little air mixed in might create explosion, so there must be an regulator to release pressure and prevent the air from mixing into the cylinder, in order to reduce the risk of explosion of next time. And with the regulator, it calls for excess gas inside the acetylene cylinder, gas cylinders and hydrogen cylinders. It is the same reason   How to improve the safety management of cylinders? Non-safe management of storage Do not lay the acetylene cylinder on the floor. The acetylene cylinder doesn’t equip with backfire preventer.   How to improve the safety management of cylinders? Solution of cylinder safe storage   Safe storage one/two/three/four cylinder     Ventilation inside the cabinet          Flip board at the bottom   The ZOYET cylinder storage cabinet equips with ventilation system and alarm system, you can link them on with on simple connection, within 5 seconds of alarming the ventilation would be started and reduce the density of flammable gas to the pre-set value of the chip.     Auto alarming system                    Anti-explosive gas detector   The ZOYET gas cylinder storage cabinet is double layer structure and equips with delicate gas detector, the sampling is taken by air diffusion and when density reaches the pre-set value, the alarm will start automatically.
