What is the system of identifying hazardous materials?
The system of identification of hazardous materials (HMIS) is a visual and numerical method that can be quickly and efficiently conveyed information on material safety. This system uses four sections, each of which can have a number on them, with higher values showing a greater risk in this category. Four categories are of health risks, the potential of weakening, physical risks with respect to reactions to other materials and personal protection that should be worn. There are four different categories within HMIS and each can be value from zero to four. Evaluation of zero means that there is no risk to this category, while four indicate an extremely high risk in this category. The system is "health", indicating the potential health risks associated with the substance and has a blue color. Evaluation of zero suggests that there are no risks, while one suggests that minor irritation may be the result of exposure to the material. Two evaluation indicates short -term health risk or less injuryIt, while the three means the main problem that probably requires immediate medical care, and four indicate that the exposure can be deadly. The "Health" category can also have a star that suggests that long -term exposure can create ongoing problems and health risks.
After "Health" is a red rod for the "boldness" of the substance. Hlavnatnost is based on the temperature at which the substance ignites. Low numbers indicate substances that are flammable or that require high temperatures, while a higher number is used for materials that can lightly ignite at room temperature or spontaneously.
The third category is colored orange and denotes the "physical risks" associated with the material. This usually concerns how the substance interacts with other materials, and high rating indicates materials that can become volatile when exposed to other substances. These materials can become explosive,If they are combined with other elements or can cause a quick erosion or disintegration. In previous versions, it was a yellow color and was called "reactivity", although it was changed in the third version of the system.
"Personal protection" is the fourth part of the system of identification of hazardous materials and is white. This part indicates how much protection it is necessary to handle these materials, and higher numbers should be received. Illustrations are often provided in this section to display specific pieces of equipment that should be worn, such as gloves or glasses.
