AEGLs (Acute Exposure Guideline Levels)

Los AEGLs representan el umbral límite de exposición para la población y son aplicables a emergencias para periodos de exposición desde 10 minutos a 8 horas. Los valores de AEGLs-1, AEGLs-2 y AEGLs-3 serán definidos para uno de los cinco periodos de tiempo (10 y 30 min., 1 h., 4 h., y 8 h.) y se distinguirán por distintos grados de toxicidad. Se cree que los niveles de exposición recomendados son aplicables a la población incluyendo niños y otros individuos que puedan ser susceptibles. Los tres AEGLs han sido definidos como:
AEGL-1
Concentración a/o por encima de la cual se predice que la población general, incluyendo individuos susceptibles pero excluyendo los hipersusceptibles, puede experimentar una incomodidad notable. Concentraciones por debajo del AEGL 1 representan niveles de exposición que producen ligero olor, sabor u otra irritación sensorial leve.
AEGL-2
Concentración a/o por encima de la cual se predice que la población general, incluyendo individuos susceptibles pero excluyendo los hipersusceptibles, puede experimentar efectos a largo plazo serios o irreversibles o ver impedida su capacidad para escapar. Concentraciones por debajo del AEGL 2 pero por encima del AEGLs 1 representan niveles de exposición que pueden causar notable malestar.
AEGL-3
Es la concentración a/o por encima de la cual se predice que la población general, incluyendo individuos susceptibles pero excluyendo los hipersusceptibles, podría experimentar efectos amenazantes para la vida o la muerte. Concentraciones por debajo de AEGL 3 pero por encima de AEGL 2 representan niveles de exposición que pueden causar efectos a largo plazo, serios o irreversibles o impedir la capacidad de escapar

ERPG (Emergency response planning guidelines)

Pretende estimar los rangos de concentración en los que se puede prever razonablemente efectos adversos observables como consecuencia de la exposición a una sustancia específica.
ERPG-1
Es la máxima concentración en aire por debajo de la cual se cree que casi todos lo individuos pueden estar expuestos hasta una hora experimentando sólo efectos adversos ligeros y transitorios o percibiendo un olor claramente definido.
ERPG-2
Es la máxima concentración en aire por debajo de la cual se cree que casi todos los individuos pueden estar expuestos hasta una hora sin experimentar o desarrollar efectos serios o irreversibles o síntomas que pudieran impedir la posibilidad de llevar a cabo acciones de protección.
ERPG-3
Es la máxima concentración en aire por debajo de la cual se cree que casi todos los individuos pueden estar expuestos hasta una hora sin experimentar o desarrollar efectos que amenacen su vida. No obstante, pueden sufrir efectos serios o irreversibles y síntomas que impidan la posibilidad de llevar a cabo acciones de protección.

ERPGs

TEEL (Temporary emergency exposure)

Se recomienda que, cuando se apliquen estos límites, la concentración en el punto receptor se calcule como la media en un periodo de 15 minutos. Son valores por defecto, que se obtienen siguiendo una determinada metodología.
TEEL-0
Concentración umbral por debajo de la cual la mayor parte de las personas no experimentarían efectos apreciables sobre la salud.
TEEL-1
Máxima concentración en aire por debajo de la cual se cree que casi todos los individuos experimentarían efectos ligeros y transitorios sobre la salud o percibirían un olor claramente definido.
TEEL-2
Máxima concentración en aire por debajo de la cual se cree que casi todos los individuos podrían estar expuestos sin experimentar o desarrollar efectos sobre la salud serios o irreversibles, o síntomas que pudieran impedir la posibilidad de llevar a cabo acciones de protección.
TEEL-3
Máxima concentración en aire por debajo de la cual se cree que casi todos los individuos podrían estar expuestos sin experimentar o desarrollar efectos amenazantes para la vida. No obstante, pueden sufrir efectos serios o irreversibles y síntomas que impidan la posibilidad de llevar a cabo acciones de protección.

Tables in PDF and Excel Format (Rev 27)

The following is a description of each table. There are introductions at the beginning of the tables that provide table-specific information.

Table 1 is an alphabetical list of chemical substances, their Chemical Abstract Services Registry Numbers (CASRNs), and some physical constants. (Future reviews will result in continuous updates to this data.) There are columns that provide the date of the original derivation of the PAC values, the date of the last technical review of the data and/or the PAC values.

Table 2 is an alphabetical list of the chemical substances and their corresponding PAC values. For the most part, values are given in parts per million (ppm) for gases and volatile liquids and in milligrams per cubic meter (mg/m³) for solids, particulates (aerosols) and nonvolatile liquids.

Table 3 is a list of the same PAC values as presented in Table 2, but the chemicals are sorted by CASRNs. They are presented in the units of the original request, either ppm or mg/m³.

Table 4 is an alphabetical list of the chemical substances and their corresponding PAC values in mass per unit volume (mg/m³). The conversion of ppm to mg/m³ was carried out assuming normal temperature and pressure, 25°C and 760 mm Hg.

CAMEO

Search SearchFind response information for thousands of hazardous materials, including fire and explosion hazards, health hazards, firefighting techniques, cleanup procedures, protective clothing, and chemical properties.
MyChemicals MyChemicalsBuild a list of chemicals. For example, substances involved in an incident response (such as a train derailment) or chemicals stored in your community.
Reactivity ReactivitySee what hazards might occur if chemicals in your MyChemicals collection are mixed together.

The CAMEO (Computer-Aided Management of Emergency Operations) software products have been valuable hazardous materials response and planning tools since the first products were introduced in 1986.

The CAMEO software suite consists of four core programs: CAMEOfm, CAMEO Chemicals, ALOHA, and MARPLOT. These applications can be used together or separately, but when they are used together, the programs interact seamlessly and information can be linked easily between them.

In addition to these core programs, there are a variety of other programs that can be used with the CAMEO software suite. Click on any of the links below to find out more about the CAMEO software suite and associated programs.

CAMEO Software Suite: Core Programs

CAMEOfm: A database application that includes several modules to assist with data management requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA). For example, you can use these modules to enter information about local facilities with hazardous chemicals and to store emergency contact information. This program can also be used to navigate between ALOHA, MARPLOT, and the downloadable version of CAMEO Chemicals.

CAMEO Chemicals: A program that allows you to search for chemicals in the CAMEO chemical database, print customized reports with response recommendations, and find out how chemicals would react if they mixed. This program is available as a website and as a downloadable program; however, only the downloadable version can share information with other programs in the CAMEO software suite.

ALOHA: A modeling application that estimates threat zones associated with hazardous chemical releases, including toxic gas clouds, fires, and explosions.

MARPLOT: A mapping program with which you can easily view and modify maps, and you can also create your own objects.

CAMEO Software Suite: Related Software

Tier2 Submit: A program that generates an electronic chemical inventory Tier II facility report, which can be used to automatically update the facility information in CAMEOfm.

RMP*Comp: A tool to help facilities complete the offsite consequence analysis that is required as part of the Risk Management Plan.

The Chemical Reactivity Worksheet: A program that allows you to see what reactions might occur when pairs of chemicals are mixed together. You can virtually mix any of the chemicals from the CAMEO chemical database, add reactive groups to the mix, print the resulting hazards in a reactivity report, and store collections of virtually mixed chemicals.
