The Inorganic Arsenic Standard requires employers to: Monitor workers' exposure to inorganic arsenic, and notify workers of exposure-monitoring results; notify anyone who cleans protective clothing or equipment of inorganic arsenic exposure; develop, update, and maintain a housekeeping and maintenance plan; monitor worker health by providing ...
Definitions. Action level means a concentration of inorganic arsenic of 5 micrograms per cubic meter of air (5 µg/m 3) averaged over any eight (8) hour period. Assistant Secretary means the Assistant Secretary of Labor for Occupational Safety and Health, U.S. Department of Labor, or designee. Authorized person means any person specifically authorized by the employer whose duties require …
Arsenic is found in both inorganic and organic forms (together referred to as total arsenic), and inorganic arsenic is generally considered more toxic than organic arsenic (Ref. 5). Consumption of ...
Biologic: A case in which elevated urinary arsenic levels (>50 µg/L for a spot or >50 µg total for a 24-hour urine) exist, as determined by commercial laboratory tests. Speciation is required in all cases where total urine arsenic is elevated to differentiate the amount of organic and inorganic arsenic. Environmental: Detection of arsenic in ...
Organic arsenic is arsenic that occurs naturally in plants and animals as part of organic compounds. Its atom is attached to a carbon or carbon-based functional group. Arsenic, occurring in nature in inorganic substances is known as inorganic arsenic. It has a simpler form than the organic one. Uses.
(b) Definitions. Action level means a concentration of inorganic arsenic of 5 micrograms per cubic meter of air (5 µg/m 3) averaged over any eight (8) hour period.. Assistant Secretary means the Assistant Secretary of Labor for Occupational Safety and Health, U.S. Department of Labor, or designee.. Authorized person means any person specifically authorized by the employer whose duties require ...
The Arsenic Standard under 29 CFR 1910.1018(n)(1)(ii) requires "that all medical examinations and procedures be performed by or under the supervision of a licensed physician." The physician interpreting the chest X-rays must be capable of giving them a rating in accordance with the criteria of the International Labor Office UICC/Cincinnati (ILO ...
Examples of work activities involving inorganic arsenic that require special attention when assessing exposure include: manufacture of arsenic compounds, the most important being the xide (As 2 O 3) formulation and application of: insecticides (lead arsenate, calcium arsenate, arsenic …
(i) Whenever observation of the monitoring of employee exposure to inorganic arsenic requires entry into an area where the use of respirators, protective clothing, or equipment is required, the employer shall provide the observer with and assure the use of such respirators, clothing, and such equipment, and shall require the observer to comply ...
Atoms of arsenic can combine with atoms of other elements to form a variety of compounds. These can be divided into two categories, "inorganic" and "organic." In this case, the term "organic" is used in its proper chemical sense, referring to molecules that have a framework of carbon atoms. In an "organic" arsenic compound, the arsenic atom is attached to a carbon that may, for ...
Inorganic arsenicals are those wood-preserving chemicals that contain arsenic. Arsenic is a naturally occurring semi-metallic element with an atomic weight of 74.92. Pure arsenic (which is rarely found in nature) exists in three allotropic forms: yellow (alpha), black (beta), and gray (gamma).
Arsenic (inorganic oxides) is on the Proposition 65 list because it can cause birth defects or other reproductive harm . Exposure to inorganic arsenic oxides during pregnancy may affect the development of the child. Proposition 65 requires businesses to determine if they must provide a warning about exposure to listed chemicals.

Inorganic Arsenic. (a) Scope and Application. (1) This section establishes requirements for the control of employee exposure to inorganic arsenic. (2) This section applies to the manufacture, reaction, release, packaging, repackaging, storage, handling, disposal or other use of inorganic arsenic except as otherwise provided by this subsection.
Arsenia, Arsenic metal [Note: OSHA considers "Inorganic Arsenic" to mean copper acetoarsenite and all inorganic compounds containing arsenic except ARSINE.] Metal: Silver-gray or tin-white, brittle, odorless solid.
Arsenic, inorganic (1910.1018) Requirements for Respiratory Protection for Inorganic Arsenic Particulate. Except for Those With Significant Vapor Pressure. Airborne Concentration (as As) or Condition of Use. Required Respirator < or = 100 µg/m 3 (micrograms per cubic meter)

In 1993, the SAB reviewed EPA's draft "Drinking Water Criteria Document on Inorganic Arsenic" and concluded that current data support an association between high levels of arsenic and cancer in humans (EPA-SAB-DWC-34-005). In 1994, the consent decree from the citizen suit was amended and EPA was required to propose a rule
