The United Nations Globally Harmonised System of Classification and Labelling of Chemicals (GHS) which has been adopted by the WHS legislation. However, the manifest and placards must reflect the ADG code information as described in Schedule 12 and 13, respectively. Class IC liquids have a flash point abov… Associate Director for Laboratory Safety You can often identify flammable liquids by the presence of warnings (as shown below) on their labels and in their safety data sheets. flammable and combustible classifications*: Flammables A flammable liquid is any liquid having a flashpoint below 1008 F (388C). The NFPA classifies all flammable liquids as Class I. Combustible liquids have a flashpoint above 100 °F. While combustible liquids having a flash point >93°C are not classified as hazardous chemicals and therefore not subject to Part 7.1, they are addressed by the general provisions in terms of hazard identification and management of associated risks, storage of combustible substances (r53), and contribution to fire loads (r359). Flammable liquids included in Class 3 are included in one of the following packing groups: Packing Group I, if they have an initial boiling point of 35°C or less at an absolute pressure of 101.3 kPa and any flash point, such as diethyl ether or carbon disulfide; Class IA have flash points below 73 degrees F and boiling points below 100 degrees F. Unstable flammable liquids also fall under the class IA sub-classification. Classification and Labelling of Chemicals Produced by the SCHC-OSHA Alliance GHS/HazCom Information Sheet Workgroup How does OSHA’s Hazard Communication Standard (HCS) define flammable liquids? Prior to bringing regulations in line with the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in 2012, OSHA considered flammable liquids to be those with a flash point below 100 °F (37.8 °C). The option of writing out an exception to normal inst… Classification Of Flammable And Combustible Liquids. The divide in the classification of flammable liquids between U.S. Labor Law and fire codes in the U.S., however, could be the root of miscommunication and potentially result in an accident. This page summarizes the relationship of GHS hazard statements, pictograms, signal words, hazard classes, categories, and precautionary statements. However, the exception to this is any mixture having components with flashpoints of 1008 F, or higher, when such components make up at least 99% of the mixtures volume. The globally harmonised system of classification and labelling of chemicals (GHS) defines a flammable liquid as a liquid having a flash point of not more than 93oC. Classifying chemicals includes placing them into categories which reflect the severity of their hazard. Current Edition: 2021 A proposal was made to zone an aircraft hanger as Zone 1, although the use of fuels handled above their flash point would be a rare event. Flammable and Combustible Liquids - §1910.106(a) (18) Combustible liquid means any liquid having a flashpoint at or above 100oF (37.8C). Flammable liquids are classified as Class I liquids. Flammable liquid means a liquid having a flash point of not more than 93°C (199.4°F). A flammable liquid is classified in one of four categories for this class according to the following table: GHS category. Flash point means the minimum temperature The NFPA also classifies fires in five different ways. It is an important challenge to all that we choose our words carefully and prepare the listener as we discuss the definition of flammable liquids, or flammable and combustible liquid classifications. The GHS classifications are now included in Schedule 11 where the prescribed quantities are listed for placarding and manifest thresholds. They are classified depending on what is fueling the fire. Class A fires are fueled by common combustibles like wood and paper. Date: 09Sept2016 1 Flammable Liquids and Solids H224 H225 H226 H227 H228 Areas with blue text indicate that information must be provided or modified by researcher prior to the SOP approval. There are no divisions within the flammable gases classification, however, these liquids may vary in their combustion levels. The production and use of chemicals is fundamental to all economies all over the world. Those with flash points above 100 °F and below 200 °F (93.3 °C) were classified as combustible liquids. However, it is also recognised that chemicals pose risks that should be indicated throughout the supply chain. "Combustible liquid" means any liquid having a flash point at or above 100 oF (37.8 oC). To determine the classification, kinematic viscosity of the sample (substance/mixture) is measured. The fire and explosion risks page provides an overview of relevant risk controls including managing hazardous areas and hot work activities and controlling ignition sources. This SOP is not a substitute for hands-on training. NFPA has six classes of flammable liquids. Further information on controlling risks associated with flammable and combustible liquids under the Work Health and Safety Act 2011 is available in the Managing risks of hazardous chemicals in the workplace published by Safe Work Australia. This recommended practice presents criteria to determine ignitability hazards in chemical process areas using flammable liquids, gases, or vapors to assist in the selection of electrical systems and equipment for safe use in Class I hazardous (classified) locations. Persons conducting a business or undertaking (PCBUs) have specific duties to store and handle their hazardous chemicals (including flammable liquids and certain combustible liquids) as follows: The repeal of the Dangerous Goods Safety Management Act 2001 has resulted in the abolition of the flammable and combustible liquids (FCL) licences administered by local governments. For flammable liquid classifications, GHS categories 1-3 are equivalent to the ADG code packing group I-III. The following exceptions apply: Flammable liquid classes are designated by the National Fire Protection Agency (NFPA) and there are six classes total based on a liquid’s closed-cup flash point and boiling point: Class IA, Class IB, Class IC, Class II, Class IIIA, and Class IIIB. Flash point is the minimum temperature at which a liquid forms a vapor above its surface in sufficient concentration that it can be ignited. The 3 sub-categories of Class I liquids are I A (flash point 73 oF, boiling point 100 oF), I B (flash point 73 oF, boiling point 100 oF) and I C (73 oF flash point 100 oF). As a result of this danger, flammable liquids need to be stored and handled according to applicable health and safety regulations. Examples of area classification – Flammable liquids for further guidance. Goods within the Flammable Liquids Classification include: Petrol, Diesel and Fuels … GHS includes criteria for the classification of health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals as well as safety data sheets. Further information on service stations shows how operators can manage their hazardous chemical risks. Classification and Labelling of Chemicals (GHS) when stored and used in workplaces, and the Australian Dangerous Goods code (ADG code) when transported. An example of flammable liquid category 4 is diesel. A chemical that meets the definition of “flammable” requires special precautions in handling, use, transfer, and storage. National Fire Protection Association (NFPA) hazard classifications for flammable and combustible liquids are listed below: Stanley Howell 29 CFR 1910.106 applies to the handling, storage, and use of flammable liquids with a flash point below 200ºF. Program Manager, Chemical Safety Under the globally harmonized system for the classification and labelling of chemicals, class 3 flammable liquids are defined as those with a flash point of up to 60°C. These six classes fall into either flammable liquids or combustible liquids. Class 3: Flammable Liquids . NPFA Flammable Liquids Class. Flammable liquids include acetone, biodiesel, diesel, ethanol and gasoline, among many others. The flash point of flammable liquids is below 37.8 degrees Celsius. Many code and standard requirements depend on the classification of a Flammable or Combustible Liquid, such as storage locations, limits in quantity, limits in storage height, grouping, arrangement, whether control areas are necessary, and auxiliary requirements such as secondary containment and sprinkler densities. A change is that GHS has introduced category 4 which overlaps with the C1 combustible liquids as defined in AS1940. An example of flammable liquid category 4 is diesel. NFPA CLASSIFICATION OF FLAMMABLE LIQUIDS S Flammable: A liquid having a flash point below 100°F (38°C) Class IA Closed-Cup Flash Point: Below 73°F (23°C) Diethyl Ether, Pentane, Ligroin, Heptane, Petroleum Ether Boiling Point: Below 100°F (38°C) 2.

Print a copy and insert into your laboratory SOP binder. According to NFPA a flammable liquid is any liquid having a flashpoint below 100 °F. The classification, labelling and packaging of chemical substances and mixtures. A flammable gas is a gas having a flammable range with air at 20 °C and a standard pressure of 101.3 kPa A pyrophoric gas is a flammable gas that is liable to ignite spontaneously in air at a temperature of 54 ºC or below A chemically unstable gas is a flammable gas that is able to react explosively even in the absence of air or oxygen A flammable gas is classified in Category 1A, 1B or 2 according to the … Safeopedia explains Flammable Liquid. These substances must be stored in flammable liquids storage cabinets. Flammable Liquids and Solids Chemical Class Standard Operating Procedure Rev. A change is that GHS has introduced category 4 which overlaps with the C1 combustible liquids as defined in AS1940. The viscosity of a non-Newtonian fluid is undefined because it depends on the method of measurement. This standard covers the following topics: Other Australian standards are also available covering a range of related topics including: QCCS (Queensland Community Care Services), NDIS (National Disability Insurance Scheme), Classification Of Flammable And Combustible Liquids, Flash point < 23°C and initial boiling point < 35°C, Flash point < 23°C and initial boiling point >35°C, prepare, maintain and implement emergency planning (sections 43 and 361), provide personal protective equipment such as organic vapour respirators (section 44), manage risks from airborne contaminants such as vapours from flammable solvents (section 49-50), manage risks from hazardous atmospheres for example, where concentration of flammable vapour exceeds five per cent of the lower explosive limit (section 51), manage fire and explosion risks (sections 52 and 355), keep the amount of flammable and combustible substances at the lowest practicable quantity (section 53), if manifest threshold quantities of hazardous chemicals are involved, provide a manifest and site plan (PDF, 689 kB) (section 347) and notify WHSQ of this circumstance (section 348), ensure storage areas are appropriately placarded (PDF, 423 kB) (sections 349-350) and safety signage erected (PDF, 103 kB) (section 353), contain and manage leaks and spills (section 357), protect containers (e.g., tanks and vessels), associated pipework and attachments from damage (section 358), provide appropriately designed and built fire protection systems (section 359). Flammable Liquids. Various notifications for hazardous chemicals are required under the WHS Regulation which are relevant to the use, storage and handling of flammable and combustible liquids including for: Service stations are a likely place that a member of the public comes into contact with flammable and combustible liquids on a regular basis. More Information Flammable liquids are classified by NFPA as Class I, which are further sub- classified, based upon additional criteria that affect fire risk, as Class IA, Class IB and Class IC - these liquids have flash points below 100 ºF (37.8 ºC) or less. A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging. 262 Alexander Street “Class I” FLAMMABLE LIQUID refers to any liquid having a flash point below 100°F and is subdivided into three classes with some examples listed below: Class IA Flash point below 73 F, boiling point below 100 F. acetaldehyde. FLAMMABLE LIQUIDS. exceeding the prescribed manifest quantity, exceeding 10 per cent of the schedule 15 (MHF) prescribed quantity, pipelines used to convey schedule 11 hazardous chemicals. control risks associated with storage and handling systems such as drums, intermediate bulk containers (IBCs), tanks, vessels, processing equipment and associated equipment (section 363). The globally harmonised system of classification and labelling of chemicals (GHS) defines a flammable liquid as a liquid having a flash point of not more than 93oC. Because the vapors of these liquids ignite and burn easily, strict storage requirements must be met. 609-258-6271, Environmental Health and Safety Thus, the use, storage and handling of diesel is subject to the requirements of the Work Health and Safety Regulation 2011 (WHS Regulation) as a hazardous chemical (Part 7.1).

Thereare two primary hazards associated with flammable liquids: explosion and fire. AS1674.1: Safety in welding and allied processes - Fire precautions in relation to welding. A licence to store flammable and combustible liquids is no longer required under the WHS Regulation. Flammable liquids are: A liquid having a flash point of = 60.5° C (141° F) Any material in a liquid phase with a flash point = 37.8° C (100° F) that is intentionally heated and offered for transport or transported at or above its flash point in bulk packaging. A flammable liquid is classified in one of four categories for this class according to the following table: For flammable liquid classifications, GHS categories 1-3 are equivalent to the ADG code packing group I-III. Divisions. Flammable liquids, n.o.s. [NFPA 30, 3.3.33.2/4.3.1 and 3.3.33.1/4.3.2] Classification of flammable and combustible liquids Information on the classification of flammable and combustible properties is available from three key documents as listed below: 1. See the Guidance on information requirements and chemical safety assessment - Chapter R.7a states: The measurement of non-Newtonian fluids is possible only with the rotational viscometer. flash point greater than or equal to 100°F (38°C). However, based on the risk of fire, these liquids are sub-classified, with six main sub-classifications. Specific information on specialised topics such as design and construction of large welded storage tanks or process plant may be available from industry associations. Flammable Liquids Code. Class IB flammable liquids have a flash point below 22.8 degrees C and a boiling point at or above 37.8 degrees C. Class IB liquids include acetone, benzene, cyclohexane, ethanol, methyl alcohol, butyl alcohol and toluene. Some examples of class 3 flammable liquids are acetone, petrol, kerosene and diesel fuel. Class IA liquid's flash point is below 22.8 degrees C and the boiling point is below 37.8 degrees C. Class IA liquids include diethyl ether, ethylene oxide, acetaldehyde and pentane.
