Purpose - Essay Example Disadvantages, in this case, refer to the problems that may be caused when the goods are consumed. The main purpose of Hazard communication is to ensure that the existing dangers or hazards of all the chemicals produced locally or imported are evaluated properly, and thus any information concerning their dangers are revealed or transmitted to the employees and the employers, as well. The transmittal is always accomplished by means of effective and comprehensive hazard programs. The programs include container labeling, material safety data sheets, as well as, employee training. Problem Definition Safety dangers or hazards related to physical features and characteristics can be easily and objectively defined with the use of testing requirements such as flammability. The definition of health hazards is more subjective and less precise. Health hazards, as understood and explained by health specialists, can result into measurable changes in the human body, for instance, reduced pulmonary function. The changes are indicated by the occurrences and the presences of symptoms and signs among the employees exposed to them. Such symptoms include a non measurable subjective feeling, as well as, shortness of breath. Determination of occupational health hazards always prove a great challenge, complicated by the fact that many of the common effects or signs occur mainly in non-occupationally exposed populations, in such away that the exposure effects are difficult or challenging to separate from the common and recurring illnesses. There are occasional situations whereby a substance may cause an effect hardly seen or visible in the population, at large. An example is angiosarcomas, which results from the exposure to vinyl chloride. This makes it easier for the establishment of the certainties that the occupational was the actual and the primary causative agent. Nevertheless, the effects are common, for instance, lung cancer. Normally, the situation becomes worse and complicated due to the fact that most chemicals have not been well adequately tested in order to determine the potential of their health hazards, and the data does not exist for the substantiation of the effects. Efforts by many scientists have come up with results and basis of categorizing effects, as well as, their definition in many ways. The general or the overall accepted terms â€Å"chronic† and â€Å"acute† used or applied in this area to come to the delineation between the effects on fundamental basis of duration or severity. â€Å"Acute† effects normally happen rapidly due to exposures that are considered short terms, and are always of short duration. â€Å"Chronic† effects occur due to long term exposures of an individual to the hazards. Unlike the Acute ones, they are of long term durations. The acute effects, that are most frequently referred, in this case, are those that defined by the US major body, the American National Standards of Institute (ANSI) s tandard for the Precautionary Labeling of Hazardous Industrial Chemicals (osha.cov). Such hazards include corrosivity, lethal dose and sensitization. Despite these being obvious health effects, they never cover adequately the chronic effect areas, excluding, for instance, the blood dyscrasias such as anemia, liver atrophy and bronchitis. The same is applicable with the term chronic effect, which is often used in the reference to only
