Irritating fumes

These new synthetic mbbers were accessible from potentially low cost raw materials and generated considerable woddwide interest. For a time, it was hoped that the polysulftde mbbers could substitute for natural mbber in automobile tires. Unfortunately, these original polymers were difficult to process, evolved irritating fumes during compounding, and properties such as compression set, extension, and abrasion characteristics were not suitable for this apphcation.

Dilution of fumes in these areas is generally required for one of two reasons either to reduce the level of harmful (toxic or irritant) fumes to a safe level, normally below the OES (Occupational Exposure Standard) or to dilute offensive odors. Care must be taken with the latter to ensure that the problem is not merely passed on to neighbors. If it is, then a local extract with air-cleaning equipment will be preferred if it is practical. Indeed, a local extract system is always preferable, since it removes the problem at source, resulting in a cleaner environment within the building. 

The substance decomposes on heating or on burning producing toxic and irritating fumes. 

Substances, which after exposure can cause irritation leading to minor injuries only, even if no treatment is undertaken. They only require use of a breathing mask with cartridge. Also included are materials that give off irritant fumes in fire conditions and those that are an irritant to skin without causing any destruction of the tissues. 

Alcohols react violently with solid calcium hypochlorite, usually causing an ignition. Sometimes very irritant fumes form. Such behaviour was mentioned with methanol, ethanol, glycerol and monoethers of diethyleneglycol. It was assumed that hypochlorites were formed. 

To avoid exposure to irritating fumes, the phosphorus pentachloride and oxychloride are, handled in the hood. The heating under reflux is also carried out in the. hood. 

Poison C Liquids or solids that evolve toxic or strongly irritating fumes heated or when exposed to air (excluding class A poisons). 

Decomposes, emits acrid smoke and irritating fumes 196.22 125 (2 mm) decomposes, emits toxic fumes of NO 217.34... 

The preparations obtained in this way can be kept a year or longer in a refrigerator. It should not be kept above 20° for more than a few hours. At temperatures in the neighborhood of 30° it may undergo a sudden decomposition without explosion but with the evolution of irritating fumes. It has been reported that the stability is increased by the addition of a few drops of acetic acid.
