General principles have been formulated, including theoretical guidelines, definitions and functions. Additionally, organizational and legislative structures have been proposed. A basic principal of the system says that each activity related to the application of chemical compounds creates a risk of adverse health and environmental effects. According to the definition adopted, chemical safety means such levels of chemical compounds in the environment, coming from various sources, which ensure that the risk of adverse health effects and other negative effects will not surpass socially acceptable levels. The chemical safety system is aimed at preventing and limiting the risk of undesirable health and environmental effects from chemical compounds. It is proposed that the system be coordinated by the National Coordinating Committee on Chemical Safety. The most urgent task of the Committee would be to draft a law on human health protection against the harmful effects of chemical compounds.</p>","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13288268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of federal health policy on occupational medicine. 联邦卫生政策对职业医学的影响。

{"title":"The effect of federal health policy on occupational medicine.","authors":"R J McCunney,&nbsp;W Cikins","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>All three branches of the federal government affect occupational medicine. Notable examples include: 1) the Department of Transportation ruling (1988) requiring drug testing in diverse areas of the transportation industry (executive branch); 2) the Workplace Drug Act (1988) calling for organizations to have a policy towards drug and alcohol abuse (legislative branch); and 3) the Supreme Court ruling on the constitutionality of drug testing in the transportation industry (1989) and that infectious diseases are a handicap in accordance with the 1973 Federal Rehabilitation Act (1987). The executive branch plays a major role in occupational medicine primarily through the Occupational Safety and Health Administration (OSHA), which issues standards based on a rule making process; the executive branch can also affect occupational medicine indirectly, as evidenced by President Reagan's Executive Order 12291 calling for Office of Management and Budget oversight of regulatory initiatives. The legislative branch enacts laws, conducts hearings, and requests reports on the operations of federal agencies. The judicial branch addresses occupational health issues when people affected by an executive ruling want to challenge the ruling; or in the case of the Supreme Court, when deliberating an issue over which two circuit courts of appeal have come to divergent opinions. The Occupational Medicine profession can participate in the political process through awareness of proposed legislation and by responding accordingly with letters, resolutions, or testimony. Similar options exist within the executive branch by participating in the rule-making process. A representative of the Governmental Affairs Committee, through periodic visits with key Washington representatives, can keep members of the American College of Occupational Medicine informed about federal legislative and regulatory activities. In appropriate cases, the organization can then take a formal position on governmental activities that affect the speciality.</p>","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13291259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was carried out in 23 managers from a big industrial plant. Evaluation of work demands and the ability to cope with them as regards mental difficulty, monotony, risk, responsibility, interpersonal conflicts and time pressure was regarded as an indicator of psychic workload. Heart rate (HR) was recorded according to the Holter method. Mean HRs were calculated for periods of work (HR work), outside work (HR home) and sleep (HR sleep). HR during work suggested the occurrence of substantial psychic load. This was supported by subjective evaluation, especially as regards responsibility, interpersonal conflicts, time pressure and mental difficulty. Work demands and the ability to cope with them could be regarded as the predictors of HR in all three periods of time considered, but especially during sleep. The prolonged influence of psychic workload on cardiovascular system reflects its intensity and may be the cause of the common occurrence of cardiovascular diseases in managerial staff.</p>","PeriodicalId":77768,"journal":{"name":"Polish journal of occupational medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13291711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
