Flammable substances labelling

Propylene oxide is classified as a flammable Hquid and ha2ardous substance in the U.S. Department of Transportation (DOT) Ha2ardous Materials Table. The DOT shipping requirement is Propylene Oxide, 3, UN 1280, PG 1. The red flammable Hquid label and red flammable placard are required on aH... 

Benzene is shipped in tank cars, tank trucks, barges, and drums. Transfers from one vessel to another are in dosed systems because benzene is a poisonous substance with acute toxic effects. It ll kill you in 5—10 minutes if you breathe too much. Red DOT flammable liquid labels are required. 

Consumer Product and Safety Commission (CPSC) - under the Department of Labor. Its goal is to protect the consumer against unreasonable risks from products specified by legislation such as the Hazardous Substances Labeling Act, Consumer Product Safety Act, and Flammable Fabrics Act.

Liquid substances with a flash point between 21 and 55 °C are classified as flammable. For labeling, only R 10 is required, without a danger symbol. It is important to note that the flammable classification is the only example of a hazardous property without a danger symbol. 

If a preparation contains flammable substances, such as ethanol, acetone or ether, there should be a warning for the patient Which H(azard) statement warning sentence (Sect. 26.3.4) and which symbol should be put oti the label. 

According to the European Regulation on ClassificatiOTi, Labelling and Packaging of Substances and Mixtures (CLP Regulation) [13] (see Sect. 26.6.3) hazard symbols are not compulsory in the labelling of medicines for patients safety however, symbols referring to the risk of flammability and explosion are needed. For flammable substances the need depends mainly on their flashpoint. 

Other important definitions of flammable substances can be found in the Classification, Packaging and Labelling of Dangerous Substances Regulations 1984 where an extremely flammable liquid is defined as one with a flash point of less than 0°C and a boiling point less than or equal to 35°C, a highly flammable liquid as one with a flash point of less than 21 °C, and a flammable substance as one with a flash point between 21°C and 55°C which when tested in accordance with Schedule 2 of the HFL Regulations does not support combustion. 

Pyrophoric and other spontaneously combustible substances will generally be identified as such on their product literature, material safety data sheets (MSDSs), or International Chemical Safety Cards (ICSCs). If transported, these substances should be identified as DOT/UN Hazard Class 4.2 materials for shipping purposes and labeled as spontaneously combustible. For pyrophoric substances, the NFPA 704 diamond for container or vessel labeling has a red (top) quadrant with a rating of 4, indicating the highest severity of flammability hazard (NFPA 704, 2001). Note that pyrophoric materials often exhibit one or more other reactivity hazards as well, such as water reactivity. 

How atoms are bonded to each other plays a significant role in the properties of the substances they create. Saturated and unsaturated fats are listed on the nutritional labels of many food products, and is medical advice about the advisability of including them in a healthy diet is offered. Saturated fats have single bonds, whereas unsaturated fats have double bonds. The triple bond in acetylene is responsible for its extreme reactivity and flammability. 

Today, almost everyone works or lives with chemicals and chemical prodncts. Over the centuries man has lived in a chemical age, but especially so during the past several decades. Many of the chemical substances can have deleterious effects on animals, humans, and the environment. These substances are capable of causing physical hazards (e.g., lire or explosion) or health hazards (such as systemic toxicity and chemical bums). Improper use of chemical substances causes a wide range of health hazards. It is the responsibility of the user to evaluate each chemical substance and know its potential to cause adverse health effects and pose physical hazards, such as flammability in the workplace. The manufacturers, importers, and distributors of different chemical substances must be sure that containers of hazardous chemicals leaving the workplace are properly labeled with the identity of the chemical and appropriate hazard warnings. In the workplace, each container must be marked with the identity of hazardous chemicals contained in it and must show hazard warnings appropriate for employee protection. 

Substances with fl.p. > 55°C should be regarded as combustible if brought to a high temperature. By 2015 the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) will replace these categories. The GHS system divides flammable liquids into four new categories ... 

Right-to-Know Working Around Hazardous Substances From worker perspective, labeling and handling of hazardous chemicals, oxidizers, poisons, corrosives, flammables, water-sensitive chemicals, spill response, and protective and emergency equipment. BNA Communications Inc. 

The court concluded that while it was possible to infer from the label used that the product might be flammable under certain conditions, there was no warning that the product s vapors or fumes could ignite and cause a tremendous explosion flours after the substance had been used. 

Signal Word The label of a hazardous substance must also contain a signal word to attract the attention of product users. The statute prescribes the word DANGER for substances which are extremely flammable, corrosive, or highly toxic highly toxic substances must also contain the word poison. The labels of all other hazardous substances must contain the signal words WARNING or CAUTION .
