Technology for chemical cleaning of steam generators at fossil stations was developed during the latter half of the 20 century. Cleaning solvents and processes were developed for application to conventional boilers. The new fleet of combined cycle generating units with heat recovery steam generators (HRSGs) has raised questions concerning the applicability of technology developed for use in con...

Cleaning is a highly physically demanding job with a high frequency of awkward postures and working environments as contributing risk factors. Participatory ergonomics is a method in which end-users take an active role in identifying risk factors and solutions. The aim of this study was to apply the participatory ergonomics method to identify cleaning problems and to evaluate the effect of a lo...

In the UK, we continue to debate the importance of hospital cleaning in relation to increasing numbers of patients acquiring meticillin-resistant Staphylococcus aureus (MRSA). However, there is little direct evidence for the effectiveness of cleaning because it has never been afforded scientific status. Hospital hygiene is usually assessed visually, but this does not necessarily correlate with ...

A few years ago, the first semi-aqueous circuit board defluxing composition was developed and introduced by Petroferm. Since that time, several other semiaqueous products have appeared, and semi-aqueous cleaning is now considered one of the leading choices for replacing ozone-depleting CFCs. Now, an advanced vapor degreasing process has been developed which offers the ease of use, fast drying, ...

BACKGROUND Contaminated environmental surfaces may play an important role in transmission of some healthcare-associated pathogens. In this study, we assessed the adequacy of cleaning practices in rooms of patients with Clostridium difficile-associated diarrhea (CDAD) and vancomycin-resistant Enterococcus (VRE) colonization or infection and examined whether an intervention would result in improv...

Because of xegulatoe, economic and community pressures, halogenated solvents, routinely used for various cleaning operations in the electronics industry, are being aggressively phased out. A fundamental undemanding of the chemical n a t u ~ of process specific contamination is essential to enable thegroper selection of appropriate alternative cleaning agents. In this study, the role and need of...

P rofessional cleaning is a basic service occupation that is carried out worldwide in many different environments, both indoors and outdoors. Cleaning workers form an important proportion of the total working population; for instance 3% in the USA, 4% in Finland, and 10% of the female working population in Spain. Cleaners often have low occupational skills and belong to the less advantaged educ...

A closed-loop recycling process is being investigated (using membrane technology) to remove soils from industrial surface cleaning Operations. This recycling process combines cleaning chemical (aqueous and semi-aqueous formulations), cleaning equipment and closedloop recyding methods tb minimize soil loading in a parts cleaning process. Closed-loop recycling and the need for it is the primary t...

Works of art prepared with acrylic emulsion paints became commercially available in the 1960s. It is increasingly necessary to undertake and optimise cleaning and preventative conservation treatments to ensure their longevity. Model artists' acrylic paint films covered with artificial soiling were thus prepared on a canvas support and exposed to a variety of wet cleaning treatments based on aqu...
