Hazmat waste compliance guidelines

日本一本道a不卡免费Arizona State University's (ASU) academic and research laboratories, along with other university operations, e.g., Facilities Management, generate a variety of hazardous chemical wastes. ASU is classified as a hazardous waste generator by the U.S. Environmental Protection Agency (EPA) and the Arizona Department of Environmental Quality (ADEQ). As a hazardous waste generator facility, ASU is required to comply with a number of hazardous waste laws and regulations. Environmental Health & Safety (EH&S) is responsible for coordinating an effective hazardous waste management program for university facilities. The primary objectives of the program are to protect human health and the environment and insure compliance with university, local, state, and federal hazardous waste regulations. University personnel and facilities involved in activities that generate hazardous waste are also subject to a number of requirements designed to protect personnel, property, and the environment.

University hazardous waste management programs can be somewhat complex and confusing because of the enormous variety of hazardous waste generated; it is the responsibility of each individual university generator to comply with accumulation requirements. The following guidelines have been prepared for university personnel to facilitate proper hazardous waste management and insure compliance with applicable hazardous waste laws and regulations, particularly individual site accumulation requirements.

日本一本道a不卡免费If there are doubts about a waste being a hazardous or non-hazardous, please contact EH&S for assistance at 480-965-8554. We will not accept unknown wastes. Disposal containers, labeling, hazardous waste tags, segregation, and scheduling of pickups must all be managed in an appropriate manner.

Severe civil and criminal penalties can be imposed upon the generator and university for irresponsible and illegal hazardous waste management and disposal practices. These procedures have been designed to properly and economically manage the university's hazardous waste while complying with all applicable federal, state and local regulations. EH&S is available for technical assistance and encourages all university personnel to utilize the service. Please contact EH&S if you have any questions regarding responsible hazardous waste management or need additional information or assistance in managing your hazardous waste.

Waste determinations

日本一本道a不卡免费State and federal hazardous waste regulations specifically require the person who generates a waste to determine if the waste is a hazardous waste by using the following methods:

  • Determine if the waste is listed as a hazardous waste in the regulations; OR

  • If the waste is not listed as a hazardous waste in the regulations, determine if the waste exhibits any of the characteristics of a hazardous waste, i.e., ignitability, corrosivity, reactivity, or toxicity, by either:

    • testing the waste according to approved EPA methods or according to an equivalent approved method; or

    • applying knowledge of the hazard characteristic of the waste in light of the materials or the processes use

For your convenience, consider all waste chemicals and chemical formulations (abandoned, used, out dated, or otherwise waste-like chemicals and formulations) as a hazardous waste unless the particular waste has been determined not a hazardous waste by EH&S.

State and federal regulations regard certain chemicals as acutely hazardous wastes日本一本道a不卡免费. These chemicals exist on a list (see acutely hazardous waste list) and must be handled separately. Chemicals which exist on this list must be reported immediately to EH&S at the point that they become a waste. No more than a total of one quart, at any time, of one or in any combination of all the chemicals on this list are allowed to remain in the laboratory once the chemical(s) become waste.

Disposal containers

  • 日本一本道a不卡免费Containers holding hazardous waste must be in good condition, non-leaking and compatible with the waste being stored.

  • 日本一本道a不卡免费Must always be closed during storage, except when it is necessary to add or remove waste.

  • Hazardous waste must not be placed in an unwashed container that previously held an incompatible waste or material.

  • 日本一本道a不卡免费Incompatible wastes must not be mixed or stored in the same container.

  • If a container holding hazardous waste is not in good condition, or if it begins to leak, the generator must transfer the waste from this container to a container that is in good condition, or manage the waste in some other way that prevents a potential for a release or contamination.

  • A storage container holding a hazardous waste that is incompatible with any waste or other materials stored nearby in containers must be separated from the other materials or protected from them by means of a partition, wall, or other device.

日本一本道a不卡免费One gallon glass hazardous waste containers with screw top lids are available at no charge to university personnel from EH&S. The original chemical container can serve as a waste container as long as the above requirements are met. Containers may exceed one-gallon as long as they meet the above stated requirements. However, containers in excess of five gallons must have prior approval from EH&S before being used as a hazardous waste storage container.

Container labeling

While hazardous waste is being accumulated, the container holding the waste must be marked with the words hazardous waste and with words that identify the contents of the container. For the purpose of waste determination, a complete inventory of wastes being accumulated in the container must be kept with the container. This can be accomplished by using hazardous waste tags and labels available through EH&S. If the original container is to be used for waste disposal, the words hazardous waste shall be legibly written with a permanent marker above or next to the chemical name. If the container is to be used for a waste different from the original contents, the original label must be removed or rendered illegible and a new label placed on the container. Hazardous waste must not be placed in an unwashed container that previously held an incompatible waste or material. The container must also be marked with the hazard associated with the waste e.g., flammable, corrosive, toxic, etc.

Hazardous waste tags

Hazardous waste tags must be filled out by the waste generator. The waste tags are used by EH&S personnel to identify waste containers and determine waste compatibility. Improper or inaccurate tagging could present a serious safety threat to EH&S personnel handling these wastes. EPA and ADEQ review the tags to determine the university's compliance with hazardous waste regulations. Inadequate or incorrect information on waste tags may result in the container not being picked up. Therefore, in the interest of efficiency, please make certain the waste tags are complete, accurate, and legible to avoid having to reschedule a pick-up. The following information must be included on the tags:

  • Chemical name:日本一本道a不卡免费 Use full chemical name, not formulas. Product names or trade names are acceptable if the manufacturer's name and address or a material safety data sheet can be supplied with the material. Also, indicate the concentration of the chemical used in percent, molarity, ppm, etc.

  • Amount:日本一本道a不卡免费 Give total volume or weight of each chemical in the container.

  • Volume percent: List percentage of the total volume of each chemical contained if more than one compound is being accumulated in the waste container.

  • Generator:日本一本道a不卡免费 List name of the individual responsible for preparing the waste and completing the waste tag.

  • Phone: Supply a telephone number at which the generator can be reached during normal university hours from 8:00 a.m. - 5:00 p.m.

  • Date: Mark the date on which the waste container is ready for pick-up.

  • Department:日本一本道a不卡免费 Identify the university department with which the generator is affiliated.

  • Building/room: List physical location in which the waste is being held for collection.

  • Category: Choose the appropriate category (hazard) descriptions from the list below and write it in the category block. Include other hazards (e.g., carcinogen) as well.

    • Biohazard/infectious 

    • Combustible material

    • 日本一本道a不卡免费Corrosive material - liquid or solid

    • Explosive

      If the waste material has more than one hazard, it should be classified according to the order of hazard as listed above. If the material is an explosive, etiologic agent, cyanide, mercury, or an organic peroxide, it will require special handling and you should contact EH&S as soon as possible.

  • pH: The pH of the solution is required for aqueous wastes. pH can be taken using pH paper or a pH meter.

Segregation

日本一本道a不卡免费All chemicals are to be considered hazardous waste when disposed. It is the policy of the university that no waste be disposed or discharged into the sanitary sewer. Whenever possible, chemical wastes should be collected and segregated by the following categories to ensure safe handling and to expedite disposal:

  • Bases, caustics and cyanides

  • 日本一本道a不卡免费Explosive and shock sensitive materials - Examples: picric acid, perchloric acid, dinitrophenyl hydrazine

  • Flammable liquids - non-halogenated organic solvents

  • Flammable solids - Examples: camphor, naphthalene

  • Gases - Examples: lecture bottles, small non-returnable cylinders

  • 日本一本道a不卡免费Inert materials - Examples: asbestos and silica

  • 日本一本道a不卡免费Inorganic acids - Examples: hydrochloric acid, hydrofluoric acid (collect separately in plastic container), sulfuric acid, nitric acid, phosphoric acid

  • Metal salts and heavy metals, (collect heavy metals separately)

  • Non-flammable organic compounds - Examples: halogenated organic solvents, glycerol, aniline;

  • Organic acids - Examples: formic acid, acetic acid

  • Oxidizers - Examples: nitrates, permanganates, perchlorates, nitric acid over 40 percent (collect separately), chromic acid cleaning solution (collect separately)

  • 日本一本道a不卡免费Peroxidizers, including peroxidizable solvents

  • Pesticides and herbicides

  • 日本一本道a不卡免费Polychlorinated biphenyls (PCB's) and dioxins - accumulate separately

  • Polymerizables

  • 日本一本道a不卡免费Reactive materials (react when exposed to water, air, or friction), Examples: alkali and alkaline earth metals, acid halides, phosphorous pentoxide, thionyl chloride

When the waste container is ready for pick-up and the waste tag has been completed, use the online日本一本道a不卡免费 hazardous waste pickup request to initiate the waste pick-up process and be sure to include the hazardous waste tag numbers on the pickup request.

Note: Do not fill waste container beyond the bottom of the neck of the container.

Waste is routinely picked up throughout the campus Monday through Friday. If you have waste in one location which totals more than 55-gallons in overall amount, or if you have a total of one quart of all acutely hazardous waste, please add a note that in the comments section of the request.

日本一本道a不卡免费Waste oil is collected and recycled and must be kept as uncontaminated as possible. EH&S requires oil to be kept separate from other chemicals, particularly solvents, metals, and pesticides. If the oil is contaminated, indicate so on the hazardous waste tag and so it can be managed and disposed of in an approved manner.
