In occupations where there is exposure to ionizing radiation, time, distance and _____ are important in considering worker safety. Some types of atmospheres contain concentrations of hazardous substances that places the worker in immediate danger because these concentrations would impair the ability to leave the work area (self rescue) or potentially cause irreversible health effects, including serious injury or death in a matter of minutes. Lead Trigger Tasks are designated by OSHA as certain highly hazardous tasks that carry the presumption of airborne exposure above the Permissible Exposure Limits. -Diethylstilbestrol Lead exposure can cause all of the following except: Silica dust is present in airborne particle of sand and rock. Administrative controls limit workers' exposures by scheduling reduced work times in contaminant areas or by implementing other such work rules. The potential dose of a contaminant is the product of the contaminant concentration, inhalation rate, exposure time, exposure frequency, and exposure duration divided by the product of averaging time and body weight. Are there some things that you should know before you choose a respirator? This break means that the respirator mask will "leak" and will not provide the needed respiratory protection.

Examples of these classes of respirators include: There are some combinations of airline respirators and SCBAs that allow workers to work for extended periods in oxygen-deficient areas or where there are airborne toxic contaminants. It is thus incumbent upon the HSE professional to understand the legal requirements where he/she operates. Transcribed Image Text: Question 4 Match each term with the appropriate description. What activities will the worker be doing while wearing the respirator (e.g., strenuous work)? Chronic exposures and health impacts are dependent upon the type, duration and intensity of exposure. In most developing countries, the wording in regulations is typically along the lines of no black smoke to be emitted, so that regulations are are most often qualitative rather than quantitative in nature. Ultimately, his goal is to help HSE professionals and companies active in the developing world tackle their HSE issues.
