Ergonomics, Work and Health
Various causes attributed for this apathy are: Lack of funds and grants Lack of knowledge, awareness and know-how Substantially less work-load Casual approach to MSD prevention for personnel Lack of advanced instrumentation or automated machines, or primitive laboratory setup.
The scene is still worse in Oral Pathology, where essentially most of the work done pertains to oral histopathology, hematology, oral cytology, with some amount of oral microbiology work.
The amount of workload varies according to the dental hospital's outdoor patients and specialist work done in Department of Oral Medicine and Oral Surgery. A huge effort for understanding and implementing the ergonomics principles is necessary.
A mismatch between the physical capacity of workers and the physical demands of their jobs can result in MSDs. After a certain period of working in an awkward posture, not only does pain occur much earlier, but remains even during rest times.
Herein, we intend to identify basic anthropometric factors, biomechanical risk factors and laboratory design considerations pertaining to incorporating ergonomic principles in actual practice. Also specific microscopy-related considerations have been discussed. No article exactly fitted to the needs and necessity of ergonomics requirements of a fully functional oral pathology laboratory setup.
Most of the literature on ergonomics involves various web links or occasional studies on the effect of laboratory work and associated MSDs. Anthropometric dimensions for each population is ranked by size and described as percentiles.
It is common practice to design for the 5th percentile female to 95th percentile male.
The forces of gravity and the compression of nerves, blood vessels, tendons and muscles cause permanent damage in our bodies. NP prevents this damage.
The more a joint deviates from the neutral position, the greater the risk of injury. The upper spine thoracic region is bent gently out and the lower spine lumbar region is bent gently in.
These bends are called kyphosis and lordosis, respectively. In NP, the spine is not rotated or twisted to left or right and it is not bent to left or right.
Whether sitting or standing, the trunk does not bend forward flexion or backward extension by much. When all four pillars are accommodated, the user can work in complete comfort for maximized performance and productivity.
These proper areas are horizontally divided into: Zone 1: Primary Work Zone: Directly in front, objects easily reached by pivoting elbows forearm swing space , in comfortable field of vision, maintenance of NP, greatest strength dexterity and visual acuity, for fine detailed work, contains objects most commonly used repetitive access Zone 2: Secondary Work Zone: Requires arm extension, within comfortable field of vision approximately 25 inches from eye , do not require fine attention, holds objects that are used less often occasional access Zone 3: Tertiary Work Zone: Requires full arm and trunk movement, holds objects that are infrequently used seldom access.
Working positions Proper working positions contribute to the physical well-being of a worker. The various types of laboratory work done in Oral Pathology and general working positions used are enumerated in Table 1.
Table 1 Open in a separate window Sitting Sitting is work for human spine and musculoskeletal system and proper seating is an extremely important ergonomic consideration. The ideal position for sitting at work exists when there is a slight curve in the lumbar region of the back, as is found in the standing position.A brief account of the work group. Job has opportunities for associated growth in competence and task accomplishment.
Its form varies according to the degree of methodological care exercised by the observer. Nonetheless the fact is that technological evolution, just like work organization, today emphasizes distributed work, whether it be between workers and machines or simply within a group. After this draft proposal is agreed upon in the WG, it becomes a committee draft CD , which is distributed to the member bodies of the SC for approval and comments.
Environmental problems, especially those relating to thermal conditions and communication in noisy environments, are dealt with in SC 5, where standards have been or are being prepared on measurement methods, methods for the estimation of heat stress, conditions of thermal comfort, metabolic heat production, and on auditory and visual danger signals, speech interference level and the assessment of speech communication.
The nature of the economic sector, the type of production or service, the size and the geographical location of the site are useful.
