Flammable and combustible liquids are present in almost every workplace. Flammable limits, like flash points however, are intended as guides not as fine lines between safe and unsafe. • It is best practice to store flammable liquids in flammable storage cabinets with self-closing doors and latching mechanism. Aisles of at least 3 feet in width shall be maintained to access doors, windows or standpipe connections. They are classified, or grouped, as either flammable or combustible by their flash points. Be sure to keep them away from any open flames. Flammable liquids, material and safe storage programs are an important part of a fire prevention program. Many flammable solids react with water and cannot be extinguished with conventional dry chemical or carbon dioxide extinguishers. The other examples of extremely flammable chemicals are ; Isopropyl alcohol (C 3 H 8 O) Ethanol (C 2 H 6 O ) Dietil eter (C 2 H 5) 2 O) Sodium (Na) Phosphor (P) Carbon disulfide ( CS 2) Methanol (CH 4 O) Glycerin (C 3 H 8 O 3) Ethyl acetate (C 4 H 8 O 2) Pyridine (C 5 H 5 N ) Chloroform (CHCl 3 ) Acetic Acid (C 2 H 4 O 2) The ease by which liquids give off flammable vapours is linked to a simple physical test called Flashpoint (ie. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air. Following these basic safe practices will help protect you from the hazards of flammable and combustible liquids: To prevent fires, flammable materials must be properly managed in the workplace. This is far below the lower flammable limit (LFL) for toluene, which is 12,000 ppm (1.2 percent). Take the time to know what flammable liquids you'r… Storage shall be prohibited except that which is required for maintenance and operation of equipment. Under hot weather conditions or if high flash point liquids are heated to temperatures around or above their flash points, a flammable vapour/air mixture will form. If repairs using approved parts cannot restore safety containers to a safe condition, discard the containers once they have been properly cleaned. Flammable liquid transfer areas are to be separated from other operations by distance or by construction having proper fire resistance. <>>> Bond and ground metal containers when transferring flammable and combustible liquids. Defining Flammable and Combustible Materials P a g e | 3 List of Flammable Liquids by NFPA Classification The following list of flammable and combustible liquids was developed to assist users in the proper classification and storage of flammable and combustible liquids in the laboratory. Bulk drums of flammable liquids must be grounded and bonded to containers during dispensing. The amount of household products that are contained in aerosol cans can seem overwhelming when looking at the entire list. For example, toluene has a workplace exposure limit of 20 ppm [50 parts of toluene per million parts of air or 0.005 percent] (ACGIH 2008 TLVs & BEIs) in many jurisdictions. Combustible waste material and residues in a building or unit operating area shall be kept to a minimum, stored in covered metal receptacles and disposed of daily. Flammable Materials - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. To control these potential hazards, several properties of these materials, such as volatility, flashpoint, flammable range and autoignition temperatures must be understood. Appropriate fire extinguishers are to be mounted within 75 feet of outside areas containing flammable liquids, and within 10 feet of any inside storage area for such materials. Such storage shall be kept in closed metal containers stored in a storage cabinet or in safety cans or in an inside storage room not having a door that opens into that portion of the building used by the public. Since it is the vapor of the liquid, not the liquid itself that burns, vapor generation becomes the primary factor in determining the fire hazard. The flash point is determined by heating the liquid in test equipment and measuring the temperature at which a flash will be obtained when a small flame is introduced in the vapor zone above the surface of the liquid. ____ Are combustible scrap, debris, and waste materials stored in covered metal receptacles, and removed from the work site promptly? Flammable and Combustible Liquids.

Some examples are; acetone, benzene and ethanol. Store flammable and combustible liquids in areas that are: Good housekeeping and equipment maintenance are important wherever any chemicals, including flammable and combustible liquids, are used. The lower flammable limit or lower explosive limit (LFL or LEL) of gasoline is 1.4 percent; the upper flammable limit or upper explosive limit (UFL or UEL) is 7.6 percent. Maintenance and operating practices shall be in accordance with established procedures which will tend to control leakage and prevent the accidental escape of flammable or combustible liquids. It has a flash point of 79°C (175°F), so it must be heated above that temperature before it can be ignited in air. Ground and bond all work and ignition-proof equipment, Ensure that there is no smoking in work areas where flammable materials are stored or used, Never store flammable materials near hot equipment or open flames, Use intrinsically safe and non-sparking tools, store flammable gas cylinders in a separate well ventilated room, ensure that cylinders are properly secured so that they cannot fall over and valves are protected from damage, always use the correct fittings and valves for the specific cylinder, do not mix and match fittings. Whether it be solids, liquids or gases, all flammable substances pose risks upon the people, property and the environment. The last type of inside storage covered by this paragraph addresses storage in “warehouses or storage buildings.” These structures are sometimes referred to as outside storage rooms. Liquids having flash points below ambient storage temperatures generally display a rapid rate of flame spread over the surface of the liquid, since it is not necessary for the heat of the fire to expend its energy in heating the liquid to generate more vapor. If the vapour concentration of the liquid in air is in the “flammable range” and the spark has enough energy, a fire or explosion can result. Recognizing that these conditions represent an “optimal” fire hazard, one has to take appropriate precautions. Lava checks for a flammable material nearby when attempting to start fires. 4 0 obj Use the smallest amount of flammable liquid necessary in the work area. Combustible liquids have a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F). endobj Liquids are often classified as "flammable" or "combustible" (OSHA, DOT, NFPA), as defined below. Some liquid transfer pumps have self-bonding hoses. At higher elevations in the mountains, the air pressure is significantly lower and solvents boil at lower temperatures. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> However, at some distance away from the solvent surface, there is a concentration of hexane vapour in the air that is in the flammable range. UN transport pictogram - 2 (white).svg 716 × 716; 3 KB. protect hoses, connections and containers from damage and inspect them regularly for signs of wear. Storage of Flammable liquids shall be in NFPA approved flammable storage lockers or in low value structures at least 50 feet from any other structure. Flammable chemicals are very useful in many chemical processes. Some flammable and combustible liquids are corrosive. All list of flammable materials wholesalers & list of flammable materials manufacturers come from members. Flammable or combustible liquids shall be drawn from or transferred into vessels, containers, or portable tanks within a building only through a closed piping system, from safety cans, by means of a device drawing through the top, or from a container or portable tanks by gravity through an approved self-closing valve. Well-designed and maintained ventilation systems remove flammable vapours from the workplace and reduce the risk of fire and health problems. Class I liquids may be used only where there are no open flames or other sources of ignition within the possible path of vapor travel. Combustible liquids have a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F). • Chemicals that require refrigeration must be stored appropriately in a U.L. ____ Are proper storage methods used to minimize the risk of fire and spontaneous combustion? aerosols Flammable liquids Definition Liquids, mixtures of liquids or liquids containing solids in solution or suspension which form flammable vapours. Under the Workplace Hazardous Materials Information System (WHMIS) 1988, flammable liquids have a flash point below 37.8°C (100°F). Make sure that flammable and combustible liquids are not left where they could block or otherwise prevent people from escaping in case of a fire. Phenol is a combustible liquid. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and … Non-flammable materials are by definition non-combustible or not easy to set on fire, according to Dictionary.com. Also included are requirements involving controls for diversion of spills away from buildings and security measures for protection against trespassing and tampering. Bonding both containers and grounding one of them “drains off” static charges and prevents the discharge of sparks. Some examples of flammable solids include: Metal powders; Alkali metals; Activated carbon; Aluminium phosphide; Sodium batteries; Next Steps. not less than 10 feet, nor more than 25 feet, from any Class I or Class II liquid storage area located outside of a storage room but inside a building. Store products, including wastes, used at the work site in proper containers. We doesn't provide storage of flammable materials products or service, please contact them directly and verify their companies info carefully. The expression “low flash – high hazard” applies. Other workplaces may only require a single, well-placed exhaust fan. Flammable solids often encountered in the laboratory include alkali metals, magnesium metal, metallic hydrides, some organometallic compounds, and sulfur. A material’s flammable or explosive limits also relate to its fire and explosion hazards. The above definitions for classification of flammable and combustible liquids are quite complex. endobj Important to practice good housekeeping and maintain equipment: Basic safety practices for flammable and combustible liquids: ExxonMobil Refinery Chemical Release and Fire, Formosa Plastics Vinyl Chloride Explosion. However, when liquids are transferred into non-conductive containers (e.g., plastic, glass), even conductive solvents may build up a charge because the plastic or glass containers decrease the rate at which the charge in the solvent dissipates. Flammable and Combustible Solids. For example, black shoe polish contains charcoal dust, mothballs are very flammable, and ping pong balls will also ignite easily if exposed to fire. Given the current security climate, it is also important that such materials do not fall into the hands of terrorists or their collaborators and be used as weapons for mass destruction. Generally, the conditions for igniting a liquid are optimal when the liquid is used at a temperature that produces a vapour in air concentration (at the surface of the liquid) that is halfway between the upper and lower flammability limits. Flammable and combustible liquids vaporize and form flammable mixtures with air when in open containers, when leaks occur, or when heated. They tend to hold a charge because they cannot conduct electricity well enough to discharge when in contact with a conducting material, like a metal pipe or container, that is grounded. This standard provides requirements to mitigate fire and explosion hazards of spray application processes that use flammable or combustible materials. Bonding can also be done by keeping a solid metal-to-metal contact between the containers themselves or between a metal container and a conducting nozzle. Liquids such as gasoline, ethanol, turpentine, potassium sulfide, napthalene and sulfur are flammable materials that give off vapors below 100 degrees Fahrenheit. Ventilation systems must be properly maintained and comply with the Building Code. Ventilation equipment used to handle solvent vaporous should meet the relevant fire code requirements. Examples of non-flammable liquids include water and carbon tetrachloride. Many flammable and combustible liquid storage areas are protected by automatic sprinkler or water spray systems and hose lines. Substances which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities. It is important that the employer assess the work site and identify potential fire hazards. We doesn't provide list of flammable materials products or service, please contact them directly and verify their companies info carefully. And the combination of silly string and party candles could prove lethal if the two come into contact. ____ Are approved containers and tanks used for the storage and handling of flammable and combustible liquids? This is particularly the case with liquefied gases such as Liquefied Petroleum Gas (LPG). If the fire is too close to the storage area, it may be impossible to get to it once the fire has started. To prevent the build up of static electricity and prevent sparks from causing a fire, it is important to bond metal dispensing and receiving containers together before pouring. Families of substances or mixtures or specific substances, such as water, air, acids, bases, oxidising agents, with which the substance or mixture could react to produce a hazardous. Many undergo dangerous chemical reactions if they contact incompatible chemicals such as oxidizing materials, or if they are stored improperly. storage of flammable materials. Everyone who works with these liquids must be aware of their hazards and how to work safely with them. Listed flammable refrigerator/freezer. Rain and snowfall fall through … If flammable vapours are likely to condense, the ducts should have welded joints. A liquid like hexanes has a low flash point and it is flammable when its temperature is in the range -33°C to -3°C (-28°F to +26°F) at sea level. Flammable liquids shall be known as Class I liquids. A fuel like kerosene is a combustible liquid with a flash point above 38°C (100°F). Flammable and Combustible Materials. Certain housekeeping requirements are given which relate to control of weeds, debris and accumulation of unnecessary combustibles. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and polishes may be flammable or combustible liquids. The amount and type of ventilation needed to minimize the hazards of flammable and combustible liquid vapours depend on such things as the kind of job, the kind and amount of materials used, and the size and layout of the work area. Solvents and fuels produced from petroleum (e.g., benzene, toluene, mineral spirits, gasoline, jet fuel) can build up a charge when they are poured or flow through hoses. Fires and explosions have resulted from the addition of non-approved parts or equipment to approved systems. View chapter Purchase book Install properly designed ventilation in storage areas. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily at normal working temperatures. No flames – hot work or smoking is be permitted in flammable or combustible liquid storage areas. Tanks shall be labeled IAW NFPA guidelines. They can be common materials that are at most work sites in gas, liquid and solid forms. the minimum temperature at which a liquid, under specific test conditions, gives off sufficient flammable vapour to ignite momentarily on the application of an ignition source) which allows them to be classed … For example, ethyl ether has an auto ignition temperature of 160°C (356°F) and its vaporous have been ignited by hot steam pipes. Flammable materials are substances that can ignite easily and burn rapidly. Specially designed and approved bonding and grounding wire assemblies are available from safety equipment retailers.

Aisles of at least 3 feet in width shall be maintained to access doors, windows or standpipe connections. They are classified, or grouped, as either flammable or combustible by their flash points. Be sure to keep them away from any open flames. Flammable liquids, material and safe storage programs are an important part of a fire prevention program. Many flammable solids react with water and cannot be extinguished with conventional dry chemical or carbon dioxide extinguishers. The other examples of extremely flammable chemicals are ; Isopropyl alcohol (C 3 H 8 O) Ethanol (C 2 H 6 O ) Dietil eter (C 2 H 5) 2 O) Sodium (Na) Phosphor (P) Carbon disulfide ( CS 2) Methanol (CH 4 O) Glycerin (C 3 H 8 O 3) Ethyl acetate (C 4 H 8 O 2) Pyridine (C 5 H 5 N ) Chloroform (CHCl 3 ) Acetic Acid (C 2 H 4 O 2) The ease by which liquids give off flammable vapours is linked to a simple physical test called Flashpoint (ie. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air. Following these basic safe practices will help protect you from the hazards of flammable and combustible liquids: To prevent fires, flammable materials must be properly managed in the workplace. This is far below the lower flammable limit (LFL) for toluene, which is 12,000 ppm (1.2 percent). Take the time to know what flammable liquids you'r… Storage shall be prohibited except that which is required for maintenance and operation of equipment. Under hot weather conditions or if high flash point liquids are heated to temperatures around or above their flash points, a flammable vapour/air mixture will form. If repairs using approved parts cannot restore safety containers to a safe condition, discard the containers once they have been properly cleaned. Flammable liquid transfer areas are to be separated from other operations by distance or by construction having proper fire resistance. <>>> Bond and ground metal containers when transferring flammable and combustible liquids. Defining Flammable and Combustible Materials P a g e | 3 List of Flammable Liquids by NFPA Classification The following list of flammable and combustible liquids was developed to assist users in the proper classification and storage of flammable and combustible liquids in the laboratory. Bulk drums of flammable liquids must be grounded and bonded to containers during dispensing. The amount of household products that are contained in aerosol cans can seem overwhelming when looking at the entire list. For example, toluene has a workplace exposure limit of 20 ppm [50 parts of toluene per million parts of air or 0.005 percent] (ACGIH 2008 TLVs & BEIs) in many jurisdictions. Combustible waste material and residues in a building or unit operating area shall be kept to a minimum, stored in covered metal receptacles and disposed of daily. Flammable Materials - Free download as Powerpoint Presentation (.ppt / .pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. To control these potential hazards, several properties of these materials, such as volatility, flashpoint, flammable range and autoignition temperatures must be understood. Appropriate fire extinguishers are to be mounted within 75 feet of outside areas containing flammable liquids, and within 10 feet of any inside storage area for such materials. Such storage shall be kept in closed metal containers stored in a storage cabinet or in safety cans or in an inside storage room not having a door that opens into that portion of the building used by the public. Since it is the vapor of the liquid, not the liquid itself that burns, vapor generation becomes the primary factor in determining the fire hazard. The flash point is determined by heating the liquid in test equipment and measuring the temperature at which a flash will be obtained when a small flame is introduced in the vapor zone above the surface of the liquid. ____ Are combustible scrap, debris, and waste materials stored in covered metal receptacles, and removed from the work site promptly?

The lower flammable limit or lower explosive limit (LFL or LEL) of gasoline is 1.4 percent; the upper flammable limit or upper explosive limit (UFL or UEL) is 7.6 percent. Maintenance and operating practices shall be in accordance with established procedures which will tend to control leakage and prevent the accidental escape of flammable or combustible liquids. It has a flash point of 79°C (175°F), so it must be heated above that temperature before it can be ignited in air. Ground and bond all work and ignition-proof equipment, Ensure that there is no smoking in work areas where flammable materials are stored or used, Never store flammable materials near hot equipment or open flames, Use intrinsically safe and non-sparking tools, store flammable gas cylinders in a separate well ventilated room, ensure that cylinders are properly secured so that they cannot fall over and valves are protected from damage, always use the correct fittings and valves for the specific cylinder, do not mix and match fittings. Whether it be solids, liquids or gases, all flammable substances pose risks upon the people, property and the environment. The last type of inside storage covered by this paragraph addresses storage in “warehouses or storage buildings.” These structures are sometimes referred to as outside storage rooms. Liquids having flash points below ambient storage temperatures generally display a rapid rate of flame spread over the surface of the liquid, since it is not necessary for the heat of the fire to expend its energy in heating the liquid to generate more vapor. If the vapour concentration of the liquid in air is in the “flammable range” and the spark has enough energy, a fire or explosion can result. Recognizing that these conditions represent an “optimal” fire hazard, one has to take appropriate precautions. Lava checks for a flammable material nearby when attempting to start fires. 4 0 obj Use the smallest amount of flammable liquid necessary in the work area. Combustible liquids have a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F). endobj Liquids are often classified as "flammable" or "combustible" (OSHA, DOT, NFPA), as defined below. Some liquid transfer pumps have self-bonding hoses. At higher elevations in the mountains, the air pressure is significantly lower and solvents boil at lower temperatures. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> However, at some distance away from the solvent surface, there is a concentration of hexane vapour in the air that is in the flammable range. UN transport pictogram - 2 (white).svg 716 × 716; 3 KB. protect hoses, connections and containers from damage and inspect them regularly for signs of wear. Storage of Flammable liquids shall be in NFPA approved flammable storage lockers or in low value structures at least 50 feet from any other structure. Flammable chemicals are very useful in many chemical processes. Some flammable and combustible liquids are corrosive. All list of flammable materials wholesalers & list of flammable materials manufacturers come from members. Flammable or combustible liquids shall be drawn from or transferred into vessels, containers, or portable tanks within a building only through a closed piping system, from safety cans, by means of a device drawing through the top, or from a container or portable tanks by gravity through an approved self-closing valve. Well-designed and maintained ventilation systems remove flammable vapours from the workplace and reduce the risk of fire and health problems. Class I liquids may be used only where there are no open flames or other sources of ignition within the possible path of vapor travel. Combustible liquids have a flash point at or above 37.8°C (100°F) and below 93.3°C (200°F). • Chemicals that require refrigeration must be stored appropriately in a U.L. ____ Are proper storage methods used to minimize the risk of fire and spontaneous combustion? aerosols Flammable liquids Definition Liquids, mixtures of liquids or liquids containing solids in solution or suspension which form flammable vapours. Under the Workplace Hazardous Materials Information System (WHMIS) 1988, flammable liquids have a flash point below 37.8°C (100°F). Make sure that flammable and combustible liquids are not left where they could block or otherwise prevent people from escaping in case of a fire. Phenol is a combustible liquid. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and … Non-flammable materials are by definition non-combustible or not easy to set on fire, according to Dictionary.com. Also included are requirements involving controls for diversion of spills away from buildings and security measures for protection against trespassing and tampering. Bonding both containers and grounding one of them “drains off” static charges and prevents the discharge of sparks. Some examples of flammable solids include: Metal powders; Alkali metals; Activated carbon; Aluminium phosphide; Sodium batteries; Next Steps. not less than 10 feet, nor more than 25 feet, from any Class I or Class II liquid storage area located outside of a storage room but inside a building. Store products, including wastes, used at the work site in proper containers. We doesn't provide storage of flammable materials products or service, please contact them directly and verify their companies info carefully. The expression “low flash – high hazard” applies. Other workplaces may only require a single, well-placed exhaust fan. Flammable solids often encountered in the laboratory include alkali metals, magnesium metal, metallic hydrides, some organometallic compounds, and sulfur. A material’s flammable or explosive limits also relate to its fire and explosion hazards. The above definitions for classification of flammable and combustible liquids are quite complex. endobj Important to practice good housekeeping and maintain equipment: Basic safety practices for flammable and combustible liquids: ExxonMobil Refinery Chemical Release and Fire, Formosa Plastics Vinyl Chloride Explosion. However, when liquids are transferred into non-conductive containers (e.g., plastic, glass), even conductive solvents may build up a charge because the plastic or glass containers decrease the rate at which the charge in the solvent dissipates. Flammable and Combustible Solids. For example, black shoe polish contains charcoal dust, mothballs are very flammable, and ping pong balls will also ignite easily if exposed to fire. Given the current security climate, it is also important that such materials do not fall into the hands of terrorists or their collaborators and be used as weapons for mass destruction. Generally, the conditions for igniting a liquid are optimal when the liquid is used at a temperature that produces a vapour in air concentration (at the surface of the liquid) that is halfway between the upper and lower flammability limits. Flammable and combustible liquids vaporize and form flammable mixtures with air when in open containers, when leaks occur, or when heated. They tend to hold a charge because they cannot conduct electricity well enough to discharge when in contact with a conducting material, like a metal pipe or container, that is grounded. This standard provides requirements to mitigate fire and explosion hazards of spray application processes that use flammable or combustible materials. Bonding can also be done by keeping a solid metal-to-metal contact between the containers themselves or between a metal container and a conducting nozzle. Liquids such as gasoline, ethanol, turpentine, potassium sulfide, napthalene and sulfur are flammable materials that give off vapors below 100 degrees Fahrenheit. Ventilation systems must be properly maintained and comply with the Building Code. Ventilation equipment used to handle solvent vaporous should meet the relevant fire code requirements. Examples of non-flammable liquids include water and carbon tetrachloride. Many flammable and combustible liquid storage areas are protected by automatic sprinkler or water spray systems and hose lines. Substances which, by interaction with water, are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities. It is important that the employer assess the work site and identify potential fire hazards. We doesn't provide list of flammable materials products or service, please contact them directly and verify their companies info carefully. And the combination of silly string and party candles could prove lethal if the two come into contact. ____ Are approved containers and tanks used for the storage and handling of flammable and combustible liquids? This is particularly the case with liquefied gases such as Liquefied Petroleum Gas (LPG). If the fire is too close to the storage area, it may be impossible to get to it once the fire has started. To prevent the build up of static electricity and prevent sparks from causing a fire, it is important to bond metal dispensing and receiving containers together before pouring. Families of substances or mixtures or specific substances, such as water, air, acids, bases, oxidising agents, with which the substance or mixture could react to produce a hazardous. Many undergo dangerous chemical reactions if they contact incompatible chemicals such as oxidizing materials, or if they are stored improperly. storage of flammable materials. Everyone who works with these liquids must be aware of their hazards and how to work safely with them. Listed flammable refrigerator/freezer. Rain and snowfall fall through … If flammable vapours are likely to condense, the ducts should have welded joints. A liquid like hexanes has a low flash point and it is flammable when its temperature is in the range -33°C to -3°C (-28°F to +26°F) at sea level. Flammable liquids shall be known as Class I liquids. A fuel like kerosene is a combustible liquid with a flash point above 38°C (100°F). Flammable and Combustible Materials. Certain housekeeping requirements are given which relate to control of weeds, debris and accumulation of unnecessary combustibles. Fuels and many common products like solvents, thinners, cleaners, adhesives, paints, waxes and polishes may be flammable or combustible liquids. The amount and type of ventilation needed to minimize the hazards of flammable and combustible liquid vapours depend on such things as the kind of job, the kind and amount of materials used, and the size and layout of the work area. Solvents and fuels produced from petroleum (e.g., benzene, toluene, mineral spirits, gasoline, jet fuel) can build up a charge when they are poured or flow through hoses. Fires and explosions have resulted from the addition of non-approved parts or equipment to approved systems. View chapter Purchase book Install properly designed ventilation in storage areas. Generally speaking, flammable liquids will ignite (catch on fire) and burn easily at normal working temperatures. No flames – hot work or smoking is be permitted in flammable or combustible liquid storage areas. Tanks shall be labeled IAW NFPA guidelines. They can be common materials that are at most work sites in gas, liquid and solid forms. the minimum temperature at which a liquid, under specific test conditions, gives off sufficient flammable vapour to ignite momentarily on the application of an ignition source) which allows them to be classed … For example, ethyl ether has an auto ignition temperature of 160°C (356°F) and its vaporous have been ignited by hot steam pipes. Flammable materials are substances that can ignite easily and burn rapidly. Specially designed and approved bonding and grounding wire assemblies are available from safety equipment retailers. Mineral wool; Gypsum boards; Asbestos cement; Perlite boards; Corriboard; Calcium silicate; Sodium silicate; Potassium silicate; Treated lumber plywood; Treated vegetable fiber (e.g., cotton, jute, kenaf, hemp, flax, etc..)
