Occupational Safety And Health

Corrosion is manifested by ulcers, cell death, and scar formation. The site of a corrosive effect can be any place on the body that the anemia symptoms chemical contacts. This is often the skin or eye but can also be any mucous membrane . The following table illustrates how a chemical can be classified as a Highly Toxic or Toxic, depending on the results of the appropriate animal tests.

An oxidizing agent is a chemical or substance that brings about an oxidation reaction. If data are available that were derived from another testing method, a description of the method should be provided along with the results of the testing.

Some affect the circulating blood elements, interfering with their function. Others damage the hematopoietic system and may prevent it from producing the blood elements. Generally speaking, corrosive materials have a very low pH or a very high pH . Examples of corrosive materials are sodium hydroxide and sulfuric acid.

  • Although specific criteria are provided, the HCS also indicates that information pertaining to other species and test methods is also relevant.
  • Hazard determination is the process of evaluating available scientific evidence in order to determine if a chemical is hazardous pursuant to the HCS.
  • The HCS provides criteria for classifying chemicals as highly toxic and toxic based on experiments that used gram albino rats or 2-3 kilogram albino rabbits.
  • However, current testing procedures accept other species and do not prescribe exact weights.

A Guide To Practical Plans For Health Life

A chemical that has a median lethal dose of more than 50 milligrams per kilogram but not more than 500 milligrams per kilogram of body weight when administered orally to albino rats weighing between 200 and 300 grams each. Polymerization is a reaction in which small molecules react with each other to form larger molecules . This raises the temperature of the monomer mixture that further accelerates the polymerization process until the reaction runs away or explodes. Oxidizers are classified by comparison with the oxidizing properties of a standard test chemical, ammonium persulfate, applied to dry, conditioned sawdust. A solid that promotes combustion of the conditioned sawdust at a greater rate than ammonium persulfate is classified as an oxidizer.

any other information that reveals the precise chemical designation and composition of the substance. Documentation of the hazard determination process and the results obtained. Exposure to live electricity can also result in a fall from height. For example, if an employee sustained an electric shock while using a ladder. ISE EXPO is an industry-leading trade show for wireless and wireline network evolution.
