Aqua Mix® Marble, Travertine, Limestone & Slate Cleaner & Resealer . Exposure limit of ammonia. NOTE: In many (but not all) Canadian jurisdictions, the exposure limits are similar to the ACGIH® TLVs®. An occupational exposure limit is an upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. If that's not possible, there are other risk controls to use. Since legislation varies by jurisdiction, contact your local jurisdiction for exact details. OSHA’s PELs tables of regulatory limits and recommended limits have been annotated to accommodate some updated information. Most of OSHA's PELs were issued shortly after adoption of the Occupational Safety and Health (OSH) Act in 1970. Some exposure limits are based on short term exposure limits (STEL). Always wash your hands after using ammonia products and before you smoke, eat or drink. NIOSH: Recommended Exposure Limit (REL): 25 ppm averaged over an eight-hour work day. Page 5 of 10.

Maximum exposure 15 minutes 1) 50: OSHA 2) maximum exposure limit: 100: Irritated eyes, throat and mucous membranes. This is the standard that must be met in every work place. Elimination or substitution. Occupational exposure to ammonia may occur through inhalation and dermal contact with this compound at workplaces where ammonia is produced or used. The most effective way to manage the risk of exposure to ammonia is to eliminate the source of exposure. Because of improved working conditions over the years, there are relatively few instances of high exposure to antimony over long periods of time (McCallum, 2005). The following table is a complete listing of OELs applicable to Ontario workplaces. The principal routes by which employees can be exposed to anhydrous ammonia are by inhalation and by contact with skin and eyes. It is a consolidation of the limits set out in the Table 1 in Regulation 833, also known as the ‘Ontario Table”, as well as applicable limits set out in the ACGIH publication, 2011 Threshold Limit Values and Biological Exposure Indices known as the “ACGIH Table” in Regulation 833. California OSHA has established an extensive list of Permissible Exposure Limits (PELs) that are enforced in workplaces under its jurisdiction. Do not store food and beverages near ammonia products. information under OSHA 1910.1020. By skin contact. CAS No. RTK Substance number: 0002 Date: May 1989 Revision: August 1998 ----- WORKPLACE EXPOSURE LIMITS No occupational limits have been established for Acetaldehyde Ammonia. OSHA has limits of something like 25 ppm for people working in industry, apparently over that amount of ammonia in the air is bad for the lungs. 7664-41-7 RTECS No. New or revised workplace exposure limits for 13 substances have been introduced from 17 January 2020. RTK Substance number: 1375 Date: March 1998 Revision: September 2004 ----- WORKPLACE EXPOSURE LIMITS * Nitrogen concentrations greater than 80% will decrease Workplace Exposure Limits: WORKPLACE EXPOSURE LIMITS (EH40/2005) OSHA-PELs: SUBSTANCE: CHEMICAL FORMULA: LTEL (8hr TWA) PPM: STEL (15 minute TWA) PPM: LTEL (8hr TWA) PPM: Ammonia NH 3 25 35 50: Arsine A s H 3 0.05 – 0.05: Bromine Br 2 0.1 0.2 0.1: Carbon Dioxide CO 2 5000 15000 5000: Carbon Monoxide CO 20 100 50: Chlorine Cl 2 – 0.5 1 ceiling * Chlorine Dioxide ClO 2 0.1 … Arsine Gas Characteristics, Toxicity, Gas Exposure Limits .

The filling limit is critical since a vessel filled with liquid to 87.5% full at 30 ºF would become 100% full of liquid if the temperature of the liquid ammonia reached 124 ºF. The permissible exposure limit (PEL or OSHA PEL) is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as high level noise. The PEL or OSHA PEL is a legal, regulatory limit on the quantity or concentration an employee can be exposed to, such as Respirable Crystalline Silica (RCS) in the air. 1. OSHA: Permissible Exposure Limit: 50 parts per million (ppm) averaged over an eight hour work day. Occupational Exposure Limits (OELs) restrict the amount and length of time a worker is exposed to airborne concentrations of hazardous biological or chemical agents.There are OELs for over 750 substances under R.R.O. Thus, OSHA at 29CFR1910.111(b)(11)(i and ii) limits the filling of ammonia vessels to 87.5% provided the temperature of the anhydrous ammonia being charged is not lower than 30 ºF. Swallowing ammonia can cause burns to the mouth, throat, and stomach and can be fatal. In water, ammonia is in equilibrium with the ammonium ion (NH4+), and the ammonia-ammonium ion equilibrium is dependent on the pH. The OSHA permissible exposure limits (PELs), as found in Tables Z-1, Z-2, and Z-3 of the OSHA General Industry Air Contaminants Standard (29 CFR 1910.1000), that were effective on July 1, 1993* and which are currently enforced by OSHA are listed on the page for each chemical in the Pocket Guide.

Englewood AO 303-843-4500 Denver AO 303-844-5285. C = Ceiling limit. New Chemical Exposure Limits under TSCA Under section 5 of the Toxic Substances Control Act (TSCA), any person who intends to manufacture (including import) a new chemical substance in the United States for commercial purposes must submit a premanufacture notice (PMN) to the EPA at least 90 days prior to manufacture (including import).
