Registered Users are required to maintain an inventory of all hazardous materials in their work areas. In addition to proper labeling, storage areas should be inspected monthly. Student Affairs. Never add water to concentrated acid; instead prepare dilute solutions by adding acid to water. Bloodborne Pathogens Exposure Control Plan. Gas cylinders need to be secured by a chain or strap half to three quarters of the way up the cylinder to prevent them from falling. If you need an easy tool to separate your chemicals, try the Quick Guide to Chemical Compatibility.
Having updated inventories improves emergency responses, helps EHS with activities such as hazardous waste determinations and safety reviews, and allows participation in the guidelines on storage of hazardous chemicals activities wide recycling program. Spill Response. For example, hydrofluoric acid must not be stored in glass, and some oxidizers should not be stored in plastic containers. Compressed Gas Guidelines on storage of hazardous chemicals activities cylinders need to be secured to a stationary object by a chain or strap two thirds of the way up the cylinder to prevent them from falling. While this book provides an excellent resource for faculty, students, and staff, it may contain information that is contradicted by current MU EHS protocols and therefore article source should be used only as a general reference source. Self-Inspection In addition to proper labeling, storage areas should be inspected monthly.

Chemical Storage HazardsThe focus of this brochure is the storage of chemicals, particularly hazardous sub-stances. Hazardous substances are • Liquids, • Gases or.
Current Safety Tip
Keep storage areas free from accumulated materials that cause tripping, fires, or explosions, or that may contribute to the harboring of rats and other pests; Place stored materials inside buildings that are under construction and at least 6 feet from hoist ways, activitiss inside floor openings and at least 10 feet away from exterior walls. 1. All projects involving hazardous chemicals, activities or devices must describe in the research plan the risk assessment process, supervision, safety precautions and methods of disposal. 2. The use of hazardous chemicals and devices and involvement in hazardous activities require direct supervision by a.
Chemical Hygiene Plan. Unwanted chemicals must also be stored according to chemical compatibility, and placed only in chemically compatible containers. Experience Marshall. Student Activities. Non-hazardous chemicals can be sorted alphabetically on shelves or in cabinets with secondary containment a chemically compatible tray, usually plastic provided for liquids and oxidizers dry and liquid.
While this book provides an excellent resource for faculty, students, and staff, it may contain information that is contradicted by current MU EHS protocols and therefore it should be used only as a general reference source. The common hazard pictures are in a PowerPoint file. Main navigation
Halogenated solvents may not be stored in metal safety cans due to the potential for corrosion. Cryogenic liquids. These items present guidelines on storage of hazardous chemicals activities potential hazards of fire or explosion, pressure buildup, embrittlement of structural materials, frostbite, and asphyxiation.
Work areas must be well ventilated. Cryogenic liquids must be stored, shipped, and handled in containers that are designed specifically for this purpose. Because of the extreme cold and splash hazards, skin protection and eye protection — preferably a face shield — should be worn when handling cryogenic liquids. First-time users of cryogenic liquids should have direct supervision and instruction from an experienced user when attempting transfers from one container to another. Use poly-coated bottles or bottle carriers when transporting chemicals that are in glass containers.
Pour chemicals carefully and close caps securely. Never add water to concentrated acid; instead prepare dilute solutions by adding acid to water. Containers holding more than five gallons should be grounded when here flammable liquids. Provide secondary containment for liquids when moving them between work areas. Inventories should be reviewed on a regular basis to identify deteriorating chemicals before they become problems, and to avoid excess purchases. Having updated inventories improves emergency responses, helps EHS with activities such as hazardous waste determinations and safety reviews, and allows participation in guidelines on storage of hazardous chemicals activities campus wide recycling program.
Registered Users are required to maintain an inventory of all hazardous materials in their article source areas. EHS also requires Registered Users to submit an inventory of hazardous materials at least annually. The on-line inventory system allows Registered Users to confirm that they have completed an annual inventory, print copies of the inventories, and query the entire database to determine if a certain hazardous material is available on campus. Make sure all labels are legible. Label all containers of hazardous materials with the chemical name and appropriate hazard class. Containers of non-hazardous materials need only to describe wanting kiss someone labeled with the chemical name.
Instructions on labeling unwanted hazardous materials can be found on the Chemical Labeling page. Common examples of chemicals that form peroxides upon aging are ethyl ether, https://modernalternativemama.com/wp-content/category/what-does/how-often-should-i-sugar-scrub-my-lips.php ether, tetrahydrofuran, and dioxane.
See the Peroxide Forming Chemicals page for a more complete listing of chemicals that can form peroxides upon aging. Avoid storing chemical containers in hard to reach areas. Containers larger than one gallon should not be stored above shoulder height. Chemicals should be click here by hazard classification to avoid incompatibilities. Once segregated by hazard class, chemicals may be stored alphabetically. It is always advisable to store liquids and oxidizers dry and liquid in secondary containment. This is especially important when incompatible chemicals are stored in the same acid cabinet or flammable materials cabinet. Contact Physical Plant if your shelves do not have the required lip, and ensure that any equipment purchases meet this requirement.
Fume hoods and laboratory benches are not acceptable storage areas for chemicals, and these areas should be maintained in an organized fashion, free of clutter. Only working quantities of chemicals should be kept in chemical fume hoods. When moving chemicals it is highly recommended to use a cart that has sides, and to use a secondary containment tray in addition in guidelines on storage of hazardous chemicals activities a spill were to occur.
Under no circumstances should chemicals be moved off of Marshall University property. Transport of chemicals in private or University vehicles is not acceptable. Contact Environmental Health and Safety with any questions. During storage all chemical containers must be labeled with the Identity of the Chemical s therein and Appropriate Hazards Warnings, in words, pictures, symbols, or a combination thereof which provide all of the hazard information. Labels on containers with mixtures of difference chemicals must indicate the constituents and approximate percentages of each. Containers of Waste Chemicals must have a completed label. A group of common hazard pictures is available for use in creating appropriate container signage.
The common hazard pictures are in a PowerPoint file. A template for the Hazardous Materials Diamond is available in Word and instructions are provided. In addition to proper labeling, storage areas this web page be inspected monthly. Gas cylinders need to be secured to a stationary object by a chain or strap two thirds of the way up the cylinder to prevent them from falling. Best practice is to secure them individually. Guidelines on storage of hazardous chemicals activities some cases it may be acceptable to secure small groups of cylinders together.
Contact Environmental Health and Safety for guidance if needed. Cylinders of liquid nitrogen should not be stored in areas that do not have ventilation, such as cold rooms. The Management of Flammable and Combustible Materials is critically important to ensure that these materials are properly used, stored, and disposed of. Click on the link above first line for more information. Flammable and combustible materials should never be stored in guidelines on storage of hazardous chemicals activities household refrigerator or freezer. Proper segregation of incompatible chemicals is critically important to preventing chemical interactions. If you need an easy tool to separate your chemicals, try the Quick Guide to Chemical Compatibility. The Hazardous Chemicals of Concern List and Storage Guide provides information about chemicals commonly found in university laboratories and divides them into compatibility groups.
The chemicals in each of the 10 groups should be stored away from the other groups. Incompatible chemicals cannot be stored together, but may be stored in the same cabinet if secondary containment is provided. For example, the following can go together in one acid cabinet: inorganic acids like sulfuric acid that are in one tray, and organic acids like acetic acid that are in another tray. Unwanted chemicals must also be stored according to chemical compatibility, and placed only in chemically compatible containers.
Cole-Parmer maintains a searchable database for determining container compatibility. Peroxide-forming chemicals present an additional hazard and must be dated when received, should be tested for presence of peroxides and the results of testing recorded on the label, and disposed of promptly if levels exceed 25 ppm.
