Fan noise is demanding and receiving much attention because of environmental laws. The basic control document is the federal OSHA limitation of 90 dB(A) at an operator s work place for 8-h exposure. There are other limitations on entire plant noise at the boundary of new plants from local ordinances which are typically more severe than the OSHA limitation. 

Concentrates are made in the same manner as dispersions but often with less work placed into the colorant—vehicle system, thus higher yields and rates are obtained and a lower cost product is made. Usually, the concentrate goes through an additional processing step with the resin in which additional energy is provided to the system, thus ensuring more dispersion. 

In work places, T-R units should be installed where there is no danger of explosion, since explosion-proof measures are very costly and units in such installations are difficult to service and maintain. It is more convenient to bear the... 

Also, when using cold processes on a downdraft table, the worker should avoid leaning over the working place or sitting too close to it, since this could disturb the flow into the exhaust and increase the spread of contaminants into the workspace. The same effects as when using fume cupboards could easily be the result (Section 10.2.3.3).

Professional society promotes the study and control of environmental factors affecting the health and well-being of factory workers, including procedures for monitoring the exposure to toxic materials in the work place. Offers laboratory accreditation and testing programs and informational pamphlets on various health and safety topics. 

It is our corporate policy to provide a safe work-place. We try to listen to our employees to understand what safety and environmental concerns they have, we believe we can improve in this area and this will be addressed in the redesigned system. 

Improvements in safety and environmental performance will come only slowly. Major accidents are rare, even with poorly managed programs, and any reduction in these will be evident only after several years. Areas where early improvements might be expected are spill response and occupational injuries where improved processes should be effective soon after installation. Work place exposure and environmental emissions may improve over a period of several months. 

Occupational mishaps me usiwlly a function of three aspects of the work place the human element, task vtiriabies (i.e., the job itselO. nnd the environmental element. 

Therefore, this room is not a siife working place and should be controlled to prevent life and health-threatening situations at this Hicility. 

Tlie OSH A. a part of tlie Department of Labor, sets exposure standards and safety rules for work places. 

The use of access equipment should meet the acceptable standards as laid down in the Construction (Working Places) Regulations 1966. 

Develop a professional perspective that will enable them to locate their work performance in the wider context of the work place and the community. 

Additionally, the lEE professional development function is exploring the possibility for Chartered Engineers in the regions to take on mentees who lack company support. There are still some reservations about ethical issues in these relationships - for example, mentors who might work for competitors of the mentee s company. This new lEE Mentoring Network will offer candidates an opportunity to find a trained mentor who is outside their immediate work place. The network is supported by the lEE Professional Development Section -principally Tony Johns (lEE Mentoring Executive Officer). A retired Chartered Engineer with many years experience as a traditional lEE mentor, Johns role is to ... 

Concurrent with this growth have been business and societal driving forces that have also influenced the R D work place. These driving forces include... 

Computers have become an accepted part of our daily lives both at home and in the work-place. This has been made more bearable by the fact that they have become unobtrusive. One now uses many computerized appliances or laboratory instruments without a conscious awareness of dealing with a computer. The mystique and ritual surrounding computers has dissipated and if frequent reference to the user s manual is necessary, it is an indication that one should probably look for a better system. The computer has become a tool and a good tool is expected to perform useful functions in an uncomplicated manner. We are no longer awed by the computer and the wonders it can perform, we have simply come to expect these "wonders". 

The largest known htiman exposures to exogenous nltrosamines have been shown to occur in the work place, particularly in the rubber and leather tanning industries. Recent data for amines, nitrosating potential and nitrosamines will be presented in the framework of assessing the extent of the various exposures.

Lethal concentration 50 (LC50) is the vapour concentration of a substance in air, which kills 50% of the animals exposed. This estimate comes from a protocol that was statistically controlled. This value depends on the animal chosen for the experiments and exposure time. The three animals that are most commonly used are in descending order rat, mouse and rabbit. It is a parameter that estimates risk level by inhalation, which is the most important means of penetration involving toxic substances in the work place. 

The arsenic compounds most commonly found in environmental and biological materials, and in working places, are arsenite and arsenate ions [As(III) and As(V)], monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), arsine, di- and tri-... 

Injection molding is one of the most widespread methods used to make polymer products. A cursory look around our homes, schools, work places or cars suffices to find an abundance of injection molded products. One of the reasons that this conversion method is so popular is that it enables us to create complex shapes in a single fabrication process. 

Occupational exposures via inhalation of acrylonitrile vapor at the work place are likely to be considerably greater than exposures outside the workplace (Table 5-1). Exposure levels may be highest for workers in plants where the chemical is synthesized (EPA 1984).
