Factory hygiene

The factory hygiene status in the right hand column of Table 11A.1 predicts, in the left hand column, the most likely microflora to be found. Conversely, a predication of factory status can be made if the corresponding microflora ate present. 

Three vulcanizing agents And extensive use in the rubber industry sulfur, insoluble sulfur, and peroxides. The chemistry of peroxides has been reviewed in Chapter 7. Rhombic sulfur is the most common form of sulfur used in the rubber industry and, other than normal factory hygiene and operational procedures, does not require any special handling or storage. Sulfur is soluble in natural rubber at levels up to 2.0 phr. Above this concentration, insoluble sulfur must be used to prevent migration of sulfur to the compound surface that is, sulfur bloom. 

Environmental Issues. The mbber industry has responded to concerns about the environment by developing new product forms for accelerators and other chemicals which improve industrial hygiene and minimize worker exposure to these materials by eliminating dust exposure and improving handling ease. Another important benefit for newer product forms is better, more consistent quaHty mbber products resulting from improved factory practices. 

The air inside a factory building can be polluted by release of contaminants from industrial processes to the air of the workroom. This is a major cause of occupational disease. Prevention and control of such contamination are part of the practice of industrial hygiene. To prevent exposure of workers to such contamination, industrial hygienists use industrial ventilation systems that remove the contaminated air from the workroom and discharge it, either with or without treatment to remove the contaminants, to the ambient air outside the factory building. 

Although not widely used for gears, oil-mist lubrication is nevertheless worth mentioning here. It is a total loss technique in which the oil is supplied in the form of fine droplets carried by compressed air. Two virtues are that the lubricant can be carried long distances through pipes without severe frictional losses, and that no oil pumps are needed since the motive power is provided by factory compressed-air lines. However, unless such systems are totally enclosed, the exhaust can create a build-up of oil-mist in the atmosphere. In order to maintain good standards of industrial hygiene, it is recommended that...

Until a decade ago, the farm may have been considered outside the pale of industrial hygiene. Today, however, the industrialization of agriculture and the advent of new insecticides and other chemicals have made the farm a virtual factory in a rural setting. On the farm, as well as in the factory, dangerous chemicals may be used safely with proper precautions. If manufacturers, processors, and distributors had to relinquish certain substances because they are toxic, American industry would be in a primitive stage. Likewise, the farmer need not bow to economic pests, but can use to the fullest advantage the potent new insecticides if he is scrupulous in protecting himself.

The quality of the final product is partly determined by the hygiene/cleaning systems in the factory. So aspects such as modeling of microbiological growth, decontamination, soil removal and the hygiene level in the process become essential.

The medical literature (Staub [24]), dealing with industrial aspects of hygiene, reports that in the one year 1900 in a German explosives factory, 41% of the workers were poisoned by dinitrobenzene. 

The wide demand for TNT during World War I compelled factories to hasten manufacture, sometimes with insufficient regard for industrial hygiene. In some countries (e.g. Great Britain, the U.S.A.) during the 1914-1918 war numerous illnesses or even deaths of people employed in TNT manufacture, filling shells etc., were registered ... 

Psychrotrophic yeasts, molds and bacteria can cause rancidity and surface spoilage in butter (Thomas and Druce, 1971), a problem less significant now than previously due to improved factory methods and hygiene. 

Hygiene on the farm and in the factory is of paramount importance in controlling microbial growth and minimising lipolysis problems. Inadequately cleaned equipment can be a major source of lipolytic psychro-trophic contaminants (Drew and Manners, 1985 Stead, 1987).
