Since the calculated ATE of the mixture is between 5 mg/kg and 50 mg/kg, the mixture itself will be classified as acute oral toxicity category 2 (H300). Mentioned above values are maximum values for appropriate route of exposure that lead to acute toxicity category 4 (CLP, Annex I, Table 3.1.1). OPP currently uses four categories. Acute toxicity refers to those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours. Category IV Very Low Toxicity: Acute Inhalation: Up to and including 0.05 mg/liter > 0.05 thru 0.5 mg/liter > 0.5 thru 2mg/liter > 2 mg/liter: Category IV Very Low Toxicity : Eye Irritation: Corrosive (irreversible deconstruction of ocular tissue) or corneal involvement or irritation persisting for more than 21 days: The acute toxicity categories listed in the Proposed Rule are also being used. GHS Classification Criteria for Acute Toxicity. The exclamation mark pictogram is used for the following classes and categories: Acute toxicity - Oral, Dermal, Inhalation (Category 4) Skin corrosion/irritation - Skin irritation (Category 2) Serious eye damage/eye irritation - Eye irritation (Category 2 and 2A) Respiratory or skin sensitization - Skin sensitizer (Category 1, 1A and 1B) The acute toxicity estimate (ATE) of ingredients is considered as follows: (a) Include ingredients with a known acute toxicity, which fall into any of the acute toxicity categories, or have an oral or dermal LD 50 greater than 2000 but less than or equal to 5000 mg/kg body AQUATIC TOXICITY H303: May be harmful if swallowed A.1 ACUTE TOXICITY-DERMAL (Category 5 not . The Signal Word, Hazards to Humans and Domestic Animals, Personal Protective Equipment (non-WPS) and First Aid statements are typically determined by the results of the six acute toxicity studies performed with the product formulation. Acute toxicity refers to the adverse effects from either (1) exposure of a single dose of substance, (2) multiple exposures within 24 hours, or (3) inhalation exposure of 4 hours. The preferred test species for evaluation of acute toxicity by the inhalation route is the rat. Acute toxicity refers to those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours. based on ppmV as follows: Category 1 (100 ppmV), Category 2 (500 ppmV), Category 3 (2500 ppmV), and Category 4 (20000 ppmV). B. Overview The four toxicity categories, from one to four are: Toxicity category I is Highly toxic and Severely irritating, Toxicity category II is Moderately toxic and Moderately irritating, hazard class, e.g., acute toxicity and flammable liquids each include four hazard categories numbered from category 1 through category 4. Acute toxicity (oral, Dermal and Inhalation), Categories 1-4. Substances can be allocated to one of four toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric criteria shown in Table 3.1.1. A Toxicity Category is assigned for each of five types of acute exposure, as specified in the table below. Acute toxicity (oral, Dermal and Inhalation), Categories 1-4. The corresponding ATE values of acute toxicity category 4 and category 2 are 500 mg/kg and 5 mg/kg respestively. Acute toxicity Category: Acute 1 96 hr LC50 (for fish) 1 mg/l and/or 48 hr EC50 (for crustacea) 1 mg/l and/or 72 or 96hr ErC50 (for algae or other aquatic plants) 1 mg/l Category: Acute 1 may be subdivided for some regulatory systems to include a lower band at L(E)C50 0 1 mg/l. Sensitization (Skin or Eye) Category 1A and 1B. Definition. H314 . Categories 1A, 1B, 1C, and 2. Acute toxicity values are expressed as (approximate) LD50 (oral, dermal) or LC50 (inhalation) values or as acute toxicity estimates (ATE). In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class).Most human hazard, precautionary statements, and human personal protective equipment statements are based upon the Toxicity Category of the pesticide product as sold or distributed. The acute toxicity categories listed in the Proposed Rule are also being used. It may take up to 30 seconds to load due to large dataset. The acute toxicity estimate (ATE) of ingredients is considered as follows: (a) Include ingredients with a known acute toxicity, which fall into any of the acute toxicity categories, or have an oral or dermal LD 50 greater than 2000 but less than or equal to 5000 mg/kg body It is aligned with UN GHS rev.7. Category IV Very Low Toxicity Acute Inhalation Up to and including 0.05 mg/liter >0.05 thru 0.5 mg/ liter >0.5 thru 2.0 mg/ liter >2mg/liter Category IV Very Low Toxicity Eye Irritation Corrosive (Irreversible destruction of ocular tissue) or corneal involvement or irritation persisting for more than 21 GHS Category 5 covers chemicals with toxicities expected to fall in the range of oral and dermal LD50 of 2000 mg/kg -5000 mg/kg, or equivalent doses for inhalation toxicity. Chemicals can be allocated to one of five toxicity categories based on acute toxicity by the Once fully loaded, it allows you to quickly find a hazard statement and signal word based on either GHS hazard category (i.e acute oral toxicity category 5) or H-code (i.e, H220). B. Since the calculated ATE of the mixture is between 5 mg/kg and 50 mg/kg, the mixture itself will be classified as acute oral toxicity category 2 (H300). GHS, the Globally Harmonized System of Classification and Labeling of Chemicals, was developed by the United Nations as a way to bring into agreement the chemical regulations and standards of different countries. N51 does not exist as an individual classification). Acute toxicity. Substances can be allocated to one of four toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric criteria shown in Table 3.1.1. ACUTE TOXICITY Summary Comparison: The GHS has five categories for acute toxicity. 1. These categories compare hazard severity within a hazard class and should not be taken as a comparison of hazard categories more generally. What does a Category 4 Hazard indicate? Acute toxicity refers to those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours. OPP currently uses four categories. However, the GHS Classification Criteria separates acute and chronic hazard classes. What does a Category 4 Hazard indicate? Acute toxicity - Oral, Dermal, Inhalation (Category 4) Skin corrosion/irritation - Skin irritation (Category 2) Serious eye damage/eye irritation - Eye irritation (Category 2 and 2A) Respiratory or skin sensitization - Skin sensitizer (Category 1, 1A and 1B) Specific target organ toxicity - Single exposure (Category 3) CLASSIFICATION CRITERIA FOR SUBSTANCES 2.

A.1.2.1 Substances can be allocated to one of four toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric cut-off criteria as shown in Table A.1.1. Skin corrosion . These categories compare hazard severity within a hazard class and should not be taken as a comparison of hazard categories more generally. of Appendix A to to 29 CFR 1910.1200, the OSHA Hazard Communication Standard (HCS 2012), acute toxicity is defined specifically as adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 . ACUTE TOXICITY Summary Comparison: The GHS has five categories for acute toxicity. Acute toxicity refers to those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours. Chemicals can be allocated to one of five toxicity categories based on acute toxicity by the Acute Toxicity Data.
