Nearly all industries, including the agri-food industry and the service industry, use chemicals in variable amounts and must therefore store them, as well as the produced chemical waste before disposal. Acting as a warehouse, the storage facility also shelters the chemicals: it protects the personnel and the environment from the effects of a spill, or an aerosol or gas emission. While designing a chemical storage facility, regardless of its size, it is thus essential to take into account all hazardous properties of chemicals, intrinsic or arising from interactions. Toxicological, chemical and physical properties define the hazards of a chemical. However in a chemical storage facility further factors add on: quantity, storage form, proximity of various chemicals, activities carried out in the facility, etc. The following example illustrates this hazard increase: hydrochloric acid and iron fillings, stored separately, are not flammable, yet when they come in contact, their reaction releases hydrogen, an extremely flammable gas, which may cause fire or explosion.

Fire prevention starts with identifying fire hazards. All members of the university community - faculty, staff, students and visitors - have a personal obligation to be aware of fire hazards and to reduce or eliminate the risk of fire on our campus. After identifying the hazards in your area, take action to eliminate or control these hazards and prevent fires. Interior decorations are a common factor in the spread of fire. Decorations used during the holiday seasons are always a large concern.
Wiring Requirements in Hazardous Locations
In the industrial sector, safety standards and regulations can add up— especially in the case of an electric motor operating in a combustible environment. It requires careful consideration of various motor characteristics and environmental variables—many of which are difficult to accurately quantify. However, according to Siemens , it is not uncommon to see the use of unqualified motors in hazardous locations and, in many cases, is something that goes undiscovered until a safety incident occurs or it is caught during an inspection from a regulatory body. The first classification to be familiar with is the Class, which defines the hazardous locations based on the type of material present. Class I — Explosive Gas Class I locations contain flammable gases or vapors in sufficient quantities in the atmosphere that could pose a risk of explosion or ignition.
Flammable Liquids Bulk Storage Regulations
Electrical equipment installation in atmosphere with flammable gases or vapors, flammable liquids, combustible dusts, ignitable fibers or flyings represents a risk for fire and explosion. In Europe and the rest of the world - but also more and more in North America - the Zone system is used. The hazardous area classification system determines required protection techniques and methods for electrical installations in the location. Class defines the general nature or properties of the hazardous material in the surrounding atmosphere. Division defines the probability of the hazardous material being present in an ignitable concentration in the surrounding atmosphere. Atmosphere containing a flammable gas, a flammable liquid produced vapor, or a combustible liquid produced vapor mixed with air that may burn or explode, having either a MESG Maximum Experimental Safe Gap 1 value less than or equal to 0. Atmosphere containing a flammable gas, a flammable liquid produced vapor or a combustible liquid-produced vapor whose MESG is greater than 0.

Understanding Explosion-Proof Motor Classifications
Staff Writer Jun 26, The majority of these mishaps can be traced to malfunctioning equipment. Electric motors, for instance, involve moving parts that generate heat and can cause arcing or sparking when overworked, posing serious fire hazards. Explosion-proof motors and hazardous location motors are specifically designed to eliminate these risks. But not all explosion-proof electric motors can handle flammable matter in the same capacity. And simply because a motor operates in a hazardous location, the motor is not necessarily explosion-proof.

Across more than countries worldwide, the KION Group designs, builds and supports logistics solutions that optimize material and information flow within factories, warehouses and distribution centers. The Group is the largest manufacturer of industrial trucks in Europe, the second-largest producer of forklifts globally and a leading provider of warehouse automation.
One common way of minimizing possibilities of electrical wiring and equipment becoming an ignition source in hazardous classified locations is to locate the equipment and wiring outside of the hazardous classified location wherever possible. This is always a practical approach and a good exercise of ingenuity, although it is not always possible. Often equipment and wiring installations have to be located within hazardous classified locations, and safe installations require a thorough understanding of more restrictive wiring rules.
Fire and explosion can result in catastrophic consequences, causing serious injuries or death of workers and others, as well as significant damage to property. A person conducting a business or undertaking PCBU must prevent the possibility of fire or explosion from an ignition of flammable substances associated with a hazardous area or a hazardous atmosphere. Section of the Work Health and Safety Regulation requires specific controls for prevention of fire and explosion associated with hazardous chemicals.
