In this context, \u201celevated\u201d means higher than what is considered ordinary for employees having direct contact with the general public outside of the facilities, service categories and operations listed in 8 CCR 5199(a)(1). Occupational exposure is presumed to exist to some extent in each of the facilities, services and operations listed in 8 CCR 5199(a)(1). Whether a particular employee has occupational exposure depends on the tasks, activities, and environment of the employee, and therefore, some employees of a covered employer may have no occupational exposure. For example, occupational exposure typically does not exist where a hospital employee works only in an office environment separated from patient care facilities, or works only in other areas separate from those where the risk of ATD transmission, whether from patients or contaminated items, would be elevated without protective measures. It is the task of employers covered by this standard to identify those employees who have occupational exposure so that appropriate protective measures can be implemented to protect them as required. Employee activities that involve having contact with, or being within exposure range of cases or suspected cases of ATD, are always considered to cause occupational exposure. Similarly, employee activities that involve contact with, or routinely being within exposure range of, populations served by correctional facilities and other facilities that house inmates or detainees, homeless shelters, or drug treatment programs are considered to cause occupational exposure. Employees working in laboratory areas in which ATPs-L are handled or reasonably anticipated to be present are also considered to have occupational exposure.Occupational exposure also includes reasonably anticipated work exposure to a source of zoonotic ATPs under conditions that, without the use of protective measures, create a significant risk of contracting the disease caused by the pathogen. Examples of such conditions include: conducting diagnostic sampling of animals reasonably suspected of infection, performing animal husbandry activities with flocks quarantined due to an increased risk of infection with zoonotic ATPs, and disposing of infected animal carcasses or their wastes.<\/p>\n","post_title":"Occupational Exposure","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"occupational-exposure-2","to_ping":"","pinged":"","post_modified":"2018-03-22 13:43:23","post_modified_gmt":"2018-03-22 20:43:23","post_content_filtered":"","post_parent":0,"guid":"http:\/\/ehs.stanford.edu\/?post_type=glossary_term&p=1816","menu_order":0,"post_type":"glossary-term","post_mime_type":"","comment_count":"0","filter":"raw","anchor":"occupational-exposure-2"},{"ID":1815,"post_author":"7","post_date":"2017-09-18 14:51:24","post_date_gmt":"2017-09-18 21:51:24","post_content":"<p>Methods that limit an employee\u2019s exposure time to noise.
