Inflammable chemicals

The combustion of a chemical substance takes place in the gaseous phase except with metals and metalloids where combustion takes place in the solid phase. This impiies that a soiid or a liquid inflammable chemical has the ability to vapourise in order to buiid an inflammable vapour-air mixture. The two indicative parameters are the boiling point and, most important, the vapour pressure of the liquid. [Pg.35]

The expression "Not Pertinent means that the data item either has no real meaning (such as the flash point of a inflammable chemical) or is not required for assessing a hazardous situation. The expression "Data Not Available" means that the information sought was not found in the general data sources consulted during the preparation of this handbook. In a few cases where important data were not available, values were estimated by usually reliable procedures all such values are labeled "(est.) . If more accurate values for those items are found, they will be included in later revisions. [Pg.3]

Residues of inflammable chemicals, particularly phosphorus (either yellow or red), must be disposed of with especial care. If possible, they should be burned or thrown into jars containing water. [Pg.200]

Inflammation. Chemically related to heparin is the GAG, hyaluronic acid. It is a natural component of the extra-cellular matrix found in connective tissues. Clinical invers-tigations have demonstrated the safety and ef-... [Pg.210]

Aside from toxic properties which nitrotoluenes possess, they are inflammable and require handling as such. Their shipment is controlled along with other inflammable chemicals in most countries, and the containers and methods of handling are subjects of legal regulation. [Pg.122]

Minimise the inventory of all dangerous, inflammable chemicals and fuels in the plant working areas (day tanks in process plants). Main storage tanks, banks of gas storages, and cylinders shall be located away from main plant, furnaces, etc. [Pg.265]

Route of coimecting cables should not pass through strong magnetic or electrical fields or near high-temperature furnaces and ducts or below pipelines carrying corrosive acids or inflammable chemicals. [Pg.172]

As mentioned previously, ISO 26262 defines functional safety as freedom of unacceptable risks based on hazards, which are caused by malfunctional behavior of E/E-systems. However, interactions of systems with E/E-functions are included as well and therefore also mechatronic systems. Whether pure mechanical systems really show not any interactions with E/E is doubtful. Furthermore, the introduction chapter of ISO 26262, which describes the scope of the norm, excludes hazards such as electric shock, fire, smoke, heat, radiation, poisoning, inflammation, (chemical) reactions, corrosion, release of energy or comparable hazards, as long as the failure was not caused by electrical components. Such hazards are caused more by the battery as well as the poisonous electrolytes in the capacitors. Whether a motor winding is an electrical device or a mechanical component is also questionable. [Pg.12]

Dimeihylamine, C2H7N, (CH3)2NH. Colourless, inflammable liquid with an ammoniacal odour, mp -96" C, b.p. 7°C. Occurs naturally in herring brine. Prepared in the laboratory by treating nitrosodimetbyl-aniline with a hot solution of sodium hydroxide. Dimethylamine is largely used in the manufacture of other chemicals. These include the solvents dimethylacetamide and dimethyl-formamide, the rocket propellant unsym-metrical dimethylhydrazine, surface-active agents, herbicides, fungicides and rubber accelerators. [Pg.260]

The choice of a solvent is of course determined primarily by its suitability for the actual recrystallisation of the given crude product. If two or more solvents appear to be almost equally suitable for the recrystallisation, the final choice should depend on the inflammability (and therefore risk in use) of the solvent, and also on its cost. It is assumed that a solvent which might have any chemical action on the compound has already been debarred. The chief solvents normally available are ... [Pg.14]

The most desirable characteristics of a solvent for recrystalhsation are (a) a high solvent power for the substance to be purified at elevated temperatures and a comparatively low solvent power at the laboratory temperature or below (6) it should dissolve the impurities readily or to only a very small extent (c) it should yield well-formed crystals of the purified compound and (d) it must be capable of easy removal from the crystals of the purified compound, i.e., possess a relatively low boiling point. It is assumed, of course, that the solvent does not react chemically with the substance to be purified. If two or more solvents appear to be equally suitable for the recrystallisation, the final selection will depend upon such factors as ease of manipulation, inflammability and cost. [Pg.123]

Atropiae (41), isolated from the deadly nightshade Airopa belladonna L.) is the racemic form, as isolated, of (—)-hyoscyamine [which is not isolated, of course, from the same plant but is typically found ia solanaceous plants such as henbane (HyosQiamus mgerl. )]. Atropiae is used to dilate the pupil of the eye ia ocular inflammations and is available both as a parasympatholytic agent for relaxation of the intestinal tract and to suppress secretions of the saUvary, gastric, and respiratory tracts. In conjunction with other agents it is used as part of an antidote mixture for organophosphorus poisons (see Chemicals in war). [Pg.537]

The likelihood that materials will produce local effects in the respiratory tract depends on their physical and chemical properties, solubiHty, reactivity with fluid-lining layers of the respiratory tract, reactivity with local tissue components, and (in the case of particulates) the site of deposition. Depending on the nature of the material, and the conditions of the exposure, the types of local response produced include acute inflammation and damage, chronic... [Pg.229]

Physiological Effects. The sulfur and nitrogen mustards act first as cell irritants and finally as a cell poison on all tissue surfaces contacted. The first symptoms usually appear in 4—6 h (4). The higher the concentration, the shorter the interval of time between the exposure to the agent and the first symptoms. Local action of the mustards results in conjunctivitis (inflammation of the eyes) erythema (redness of the skin), which may be followed by blistering or ulceration and an inflammatory reaction of the nose, throat, trachea, bronchi, and lung tissue. Injuries produced by mustard heal much more slowly and are much more Fable to infection than bums of similar intensity produced by physical means or by other chemicals. [Pg.398]

Interest has continued with these materials because of their non-inflammable nature (they will not bum, even in pure oxygen), their excellent chemical resistance, including that of nitrogen tetroxide and chlorine trifluoride, a low Tg of -51°C and an extremely low solubility parameter of 10.6MPa. ... [Pg.382]

The chemical resistance of celluloid is not particularly good. It is affected by acids and alkalis, discolours on exposure to sunlight and tends to harden on aging. More seriously it is extremely inflammable, this being by far the greatest limitation of the material. [Pg.619]

The high inflammability and relatively poor chemical properties of celluloid severely restrict its use in industrial applications. Consequently, the material is used because of the following desirable characteristics. [Pg.619]

Hepatic Hepatic means "pertaining to the liver." For example, hepatitis is inflammation of the liver. Liver disorders are sometimes marked by jaundice, a yellowish coloration to the whites of the eyes and skin. Certain chemicals are hepatotoxins (toxic to the liver), usually as a result of chronic exposure. One example is carbon tetrachloride (CCI4). [Pg.531]
