Liquid corrosives, chemical hazard

Flammable Liquid, Corrosive SAFETY PROFILE Poison by inhalation. Moderately toxic by ingestion. A human systemic irritant by inhalation. Violent hydrolysis reaction with water or steam produces heat, acetic acid, HCl, and other corrosive chlorides. May decompose during preparation. Dangerous fire hazard when exposed to heat or flame. Explosion hazard by spontaneous chemical reaction with dimethyl sulfoxide or ethanol. Also incompatible with PCI3. When heated to decomposition it emits highly toxic fumes of phosgene and Cl . To fight fire, use CO2 or dry chemical. See also CHLORIDES. [Pg.18]

According to this classification an inflammable liquid or solid chemical is given a number designating its class, and a red color that indicates its physical or chemical hazard such as flammability. For toxic, corrosive, explosive radioactive material a container should be marked with different numbers and colors (Fig. 2.4). [Pg.27]

Mixed waste contains both radioactive and chemically hazardous materials such as toxic, corrosive, flammable, or explosive materials. The radioactive component may be either HLW or LLW. All liquid HLW is mixed waste, usually in the presence of organic solvents or heavy metals in addition to radioactive components. Disposal of mixed wastes is regulated by the EPA under the Resource Conservation and... [Pg.238]

The American National Standards Institute (ANSI) has established a voluntary standard for chemical labeling, ANSI Z129.11994, Hazardous Industrial Chemical Precautionary Labeling, which includes readily identifiable symbols for poisons, corrosives, flammables, and explosives. Irritants, combustible liquids, pyrophoric chemicals, oxidizers, sensitizers, physiologically inert vapors, gases and other hazardous materials are also addressed. [Pg.38]

Determination of the type and frequency of inspection on the risk is what risk-based inspection (RBI) is all about. Risk is quantitatively determined by the probability of failure and the consequences thereof. This implies that the type of failure (blistering, cracking, etc.) and its rate are known through experience, testing, or other information. The owner, on the basis of the contained liquid, its amount, and its hazardous nature, determines the consequences. In almost all cases, fluoropolymers are used for corrosive and hazardous chemicals, and the consequences of failure are quite severe. This has led to the general guidelines for type and frequency of inspections shown in Table 9.1. [Pg.313]

Batteries that require a liquid electrolyte are called wet batteries. Corrosive battery fluid refers to either acid electrolytes syn. battery acid, like the common lead-acid automobile battery which uses a solution of sulphuric acid, or alkali electrolytes syn. alkaline corrosive battery fluid, like potassium hydroxide (1310-58-3) solutions in nickel-cadmium and other alkaline battery systems. Dry batteries or dry cells, like all primary batteries, use electrolytes immobilized in pastes, gels, or absorbed into separator materials. Some batteries are loaded with a dry, solid chemical (e.g., potassium hydroxide) which is diluted with water to become a liquid electrolyte. The hazards associated with handling and transportation prior to use are thereby reduced. [Pg.28]

L/D ratio See screw length-to-diameter ratio, leach To extract a soluble component from a mixture by the process of percolation. See percolation, leachate A contaminated liquid that drains from landfills and must be treated before entering the environment. It can contain decomposed wastes, decomposition byproducts, heavy metals, or bacteria. See geomembrane, lead 1. The distance in an axial direction from the center of an element such as a screw flight at its outside diameter to the center of the same flight. See directional property. 2. A heavy metal, Pb is hazardous to one s health if inhaled or swallowed. Its use is restricted. In plastics it is found in certain products, such as additives. Pb can be used in safe environments since it has excellent performance properties, such as resisting attack by many corrosive chemicals and is impervious to x-ray and gamma radiation. See hazard x-ray. [Pg.333]

FAST-ACT is a sorbent treatment developed by Nanoscale Corporation of Manhattan, Kansas, USA. It is a broad spectrum chemical hazard response technology developed to counter a range of known or unknown hazards. The technology has been found to be effective against chemical agents in both liquid and vapor forms. It is a dry powder formulation and is non-toxic, non-corrosive and non-flammable. The product can also be used over a wide range of temperatures and environmental conditions. ... [Pg.270]

Train employees on each specific chemical used, or train each employee based upon hazard categories (flammable liquids, corrosive material, carcinogens). [Pg.457]

Corrosive chemicals are common hazards in the laboratory and also in our homes in the form of cleaning agents. Corrosives are defined as chemicals that cause harm or injury by damaging and destroying tissue, such as eyes or skin, at the point of contact or the exposure site (see Figure 5.1.1.1). Table 5.1.1.1 lists some corrosives that may be encountered in the first year of chemistry laboratory experiments. Corrosives can be gases, liquids, solids, or solutions. [Pg.219]

PIMs share considerable similarities with the more well-known liquid-liquid extraction techniques, commonly known as solvent extraction (SX), in which an extractant is dissolved in a large volume of solvent. PIMs are principally differentiated by the replacement of the solvent with a polymer matrix. Solvents used in SX are commonly volatile, toxic and flammable (e.g., kerosene, decane) and extractants are commonly corrosive and harmful to the environment if released (e.g., substituted aUcylamines, substituted alkylphosphorus compounds). By replacing the solvent with a relatively inert polymer matrix, the chemical hazards associated with separation processes are considerably reduced and solvent-associated fire hazards are essentially eliminated. Additionally, by entrapping the extractant in the polymer matrix, occupational exposure to the extractant could be considerably reduced. [Pg.234]

Bromine is considered a moderate fire hazard. As liquid or vapor, it can enter spontaneous chemical reactions with reducing materials. It is a very powerful oxidizer. Bromine is considered a highly dangerous material. Upon being heated, it emits highly toxic fumes. It will react with water or steam to produce toxic and corrosive fumes. [Pg.476]

Adsorbers, distillation colunuis, and packed lowers are more complicated vessels and as a result, the potential exists for more serious hazards. These vessels are subject to tlie same potential haz. uds discussed previously in relation to leaks, corrosion, and stress. However, llicse separation columns contain a wide variety of internals or separation devices. Adsorbers or strippers usually contain packing, packing supports, liquid distributors, hold-down plates, and weirs. Depending on tlie physical and chemical properties of the fluids being passed tlirough tlie tower, potential liazards may result if incompatible materials are used for llie internals. Reactivity with llie metals used may cause undesirable reactions, which may lead to elevated temperatures and pressures and, ullinialely, to vessel rupture. Distillation columns may contain internals such as sieve trays, bubble caps, and valve plates, wliicli are also in conlacl with tlie... [Pg.465]
