Housekeeping mechanisms

Limitation of skin contact, e.g. by covering benches, pre-mixing of resins, good housekeeping, mechanization. 

Sanitation includes housekeeping, inspection, physical and mechanical methods, chemical methods, and biological methods (Mills and Pedersen, 1990) and is critical for the production, manufacture, and distribution of... 

Poor housekeeping may increase the failure or breakdown of electrical and mechanical equipment. Even without considering the possibility of a resulting fire or explosion, electrical and mechanical breakdowns can result in damage or destruction of major pieces of equipment or injury to personnel. Poor housekeeping can lead to breakdowns in the following ways ... 

The examples noted above serve to highlight where advances in the understanding of basic cellular housekeeping processes and the consequences of their perturbation can have a very significant impact on determining the mechanism of adverse health outcomes and the subsequent assessment of risk. Thus, studies of mutagenicity play an important role in hazard identification, dose-response assessment, and the characterization of risk. 

This chapter will discuss cell water, the regulation of cell volume, and the modifications produced by cell pH. These topics are housekeeping functions and do not have the glamour of genetic engineering. Nevertheless, it is quite probable that one of the first requirements for life to evolve was a guarantee of a stable fluid environment. Mechanisms had to be established that would regulate the cell content of water. 

Improved housekeeping can often lead to reduced emissions and waste.200 The leaky valves and seals can be fixed or they can be replaced with new designs that minimize emissions.201 These include diaphragm valves, double mechanical seals with interstitial barrier liquids, magnetic drives, better valve packings, filled fabric seals for floating roof tanks, and so on. Older plants may have some of the...
