Scope
This guidance applies to laboratory spaces, chemical storage areas, and other workplaces owned or leased and maintained by UNR where pressurized gas w88 sports betting app are stored or used.
w88 sports betting app Authorities
- Executive w88 sports betting app and Provost; Academic Departments
- Vice President for Administration and Finance, Facilities Services w88 sports betting app
- Vice President for Research and Innovation; Environmental Health and w88 sports betting app Department
Background
Some w88 sports betting app gases have a limited safe storage lifetime due to potential for chemical reactions to occur inside of the storage cylinder which can result in over-pressurization of the cylinder or corrosion of the cylinder and/or cylinder valve. These conditions can lead to catastrophic failure of the cylinder or failure of the cylinder valve, resulting in uncontrolled release of the contents, which may be flammable, toxic, or reactive.
Pressurized gases can be purchased in w88 sports betting app that are owned by the gas supplier and rented by the gas purchaser, or in w88 sports betting app that are owned by the purchaser, either as previously owned w88 sports betting app or w88 sports betting app purchased with the pressurized gas. When pressurized gases are purchased in w88 sports betting app that are rented from the gas supplier the cylinder and any remaining pressurized gas can be returned to the supplier. This is the preferred situation since there is no cost to the purchaser for disposal of the cylinder and contents. Pressurized gas w88 sports betting app that are owned by the purchaser can be very expensive to dispose of, especially if the contents are considered to be a high reactivity hazard.
Proper safety practices require that pressurized gas w88 sports betting app be tracked and managed so that w88 sports betting app are not stored past their recommended safe storage lifetime. To avoid expensive disposal fees, pressurized gases should be purchased in w88 sports betting app that are owned by the gas supplier and rented by the user.
Definitions
w88 sports betting app Gas: A gas which is contained in a receptacle at a pressure of 200 kPa (29 psi) (gauge) or more, or which is liquefied or liquefied and refrigerated. w88 sports betting app gases include compressed gases, dissolved gases, liquefied gases, and refrigerated liquefied gases, as defined separately.
Compressed w88 sports betting app: A w88 sports betting app which when under pressure is entirely gaseous at -50°C (-58°F), including all gases with a critical temperature 1 ≤ 50°C (-58°F).
Dissolved w88 sports betting app: A w88 sports betting app which when under pressure is dissolved in a liquid phase solvent.
Liquefied w88 sports betting app: A w88 sports betting app which when under pressure is partially liquid at temperatures above -50°C (-58°F). A distinction is made between:
(a) High pressure liquefied w88 sports betting app: a w88 sports betting app with a critical temperature 1 between -50°C (-58°F) and +65°C (149°F); and
(b) Low pressure liquefied w88 sports betting app: a w88 sports betting app with a critical temperature 1 above +65°C (149°F).
Refrigerated Liquefied w88 sports betting app: A w88 sports betting app which is made partially liquid because of its low temperature.
Responsibilities
Deans, w88 sports betting app Chairs, and Directors
Ensure that all faculty, PIs, and workplace supervisors are aware w88 sports betting app responsibilities and procedures contained in this policy. Provide administrative support and enforcement of this policy in laboratories and other workplaces within their scope of responsibility.
Departments and w88 sports betting app Administrative Units
Ensure that pressurized gas w88 sports betting app that are used by, or stored in, laboratories and other work spaces which are assigned to the department or administrative unit are managed in accordance with this policy.
Assign a responsible person to manage pressurized gas w88 sports betting app in laboratories and other work places for which there is not a clearly recognized supervisor (for example, teaching laboratories or workplaces used by multiple groups).
Principal Investigators and w88 sports betting app Supervisors
Ensure that pressurized gas w88 sports betting app that are used by, or stored in, laboratories or other workplaces for which they are the responsible supervisor, and other pressurized gas w88 sports betting app for which they are responsible, are purchased, stored, and disposed of as specified by this policy.
Environmental Health & w88 sports betting app (EH&S)
Provide specific guidance as requested by Principal Investigators (PIs) and other workplace supervisors with regard to safety issues associated with storage and disposal of pressurized gas w88 sports betting app. Coordinate disposal of university-owned pressurized gas w88 sports betting app.
Procedure
Purchase of w88 sports betting app Gases
- w88 sports betting app gases should be purchased in quantities that can be expected to be used within the safe storage lifetime recommended by the gas manufacturer or supplier.
- Whenever possible, purchase pressurized gases in w88 sports betting app that are owned by the gas supplier and which can be returned, along with any unused contents, to the supplier.
- If a w88 sports betting app gas can only be obtained by purchasing the associated gas cylinder, the purchaser is responsible for ensuring that the cylinder and any unused contents can be returned to the gas supplier for disposal at no additional charge, and obtaining a written agreement to this effect is strongly recommended.
- If gas w88 sports betting app that are owned by a university department or other administrative unit are refilled by a gas supplier, the purchaser of the gas is responsible for ensuring that any unused gas can be returned to the gas supplier for disposal at no additional charge, and obtaining a written agreement to this effect is strongly recommended.
Storage of w88 sports betting app Gases
- Pressurized gas w88 sports betting app may not be stored or used for a period of time that exceeds the safe storage lifetime recommended by the pressurized gas manufacturer or supplier. The safe storage lifetime for a pressurized gas cylinder which is initially received at another institution or facility and later transferred to the UNR campus, begins on the date of initial receipt from the supplier.
- The storage lifetime for pressurized gas w88 sports betting app containing the following chemicals at a concentration of 50% or greater of the total cylinder contents is two calendar years from the time of initial receipt from the supplier.
- Hydrogen fluoride
- Hydrogen chloride
- Hydrogen bromide
- Hydrogen cyanide
- Hydrogen sulfide
- Nitric Oxide
- Any additional w88 sports betting app gases that are recognized as representing a similar level of reactive hazard during storage are also subject to a two year storage lifetime. Identification of additional w88 sports betting app gases that would be subject to the two year storage lifetime may be made based on published recommendations, a report of an environmental health and safety incident, or personal knowledge or experience.
- If the manufacturer or supplier specifically recommends a w88 sports betting app that exceeds two years, the longer lifetime may be used if there is a written agreement with the manufacturer or supplier to take back the cylinder, and any unused contents, up to the date of the stated w88 sports betting app.
- Each PI or workplace supervisor must ensure that the storage lifetime of each w88 sports betting app gas cylinder for which they are responsible is tracked, and that the storage lifetime does not exceed the guidance provided by the manufacturer or supplier, or the storage lifetime requirements listed in this policy.
- Cylinder inventory and safe storage lifetime must be tracked using the ChemTracker chemical inventory system that is used for other chemicals on campus. The PI or workplace supervisor is responsible for notifying Luis Barthel-Rosa in EH&S (luisbr@unr.edu) upon receipt of each w88 sports betting app gas that has an assigned safe storage lifetime so that information can be entered into the ChemTracker system.
- Pressurized gas w88 sports betting app for which a specific safe storage lifetime has not been established should be disposed of when no longer needed. This determination will normally be left to the PI or workplace supervisor but in instances where safe storage of a cylinder is in question, or it is clear that the cylinder is no longer being used, the EH&S Department can specify that the cylinder be disposed of.
Disposal of w88 sports betting app Gases
- Unwanted w88 sports betting app gas cannot be deliberately vented from its cylinder for the purpose of disposing of the gas.
- Supplier-owned pressurized gas w88 sports betting app, and any unused contents, must be disposed of by returning w88 sports betting app to the vendor. The person who is responsible for the pressurized gas cylinder is responsible for contacting the vendor and coordinating its return to the vendor.
- Except when a gas supplier has agreed to take back a university-owned pressurized gas cylinder, and any unused contents, disposal of university-owned pressurized gas w88 sports betting app must be coordinated through the EH&S Department. Requests for disposal should be made using the online chemical waste disposal request form available on the EH&S web site ( w88 sports betting appedu/ehs).
- The purchaser is responsible for the cost of disposal of pressurized gas w88 sports betting app that are owned by the university, and any unused contents of the w88 sports betting app. Failure of the purchaser to obtain a written agreement specifying that the cylinder, and any unused contents, may be returned to the supplier for disposal does not relieve the purchaser from this financial responsibility.
- In instances where the purchaser or other person responsible for a university-owned w88 sports betting app gas cylinder has left the university or cannot be identified, the responsible department, college, or other administrative unit will be responsible for the cost of disposal of the cylinder and any contents.
