- it is capable, under standard temperature and pressure, of causing fire through friction, absorption of moisture, or spontaneous chemical changes and, when ignited, burns vigorously and persistently so as to create a hazard;

- it is a flammable compress gas, or can form a flammable gas mixture;

- is it an oxidizer that stimulates combustion of organic materials.

(2) A material is corrosive if it is a liquid that has a pH of less than 2 or greater than 12.5 (or corrodes certain grades of steel).

(3) The material is reactive; that is, it is normally unstable, reacts violently with water, is capable of detonation if exposed to some initiating source, or produces toxic gases.

(4) The material 1) has an LD₅₀ less than 50 mg/kg (oral, rat), an LC₅₀ less than 2 mg/L (rat), or a dermal LD₅₀ less than 200 mg/kg (rabbit), or is otherwise capable of causing or significantly contributing to an increase in serious, irreversible, or incapacitating reversible, illness, or 2) is listed in Appendix VIII in 40 CFR 261.
 
 

b. Procedures should be designed, where possible, to eliminate or minimize the amount of waste materials generated. This should preferably be included as part of the lab experiment for student laboratories.

c. Whenever possible, spent solvents should be recovered and recycled by distillation or chromatographic purification for reuse.

d. Aqueous solutions of acids and bases should be neutralized before flushing down the drain with large volumes of water.

e. Solutions containing toxic heavy metals such as mercury, lead, chromium, silver, etc. should be precipitated and the metal recovered in solid form for subsequent disposal as a solid waste.

f. Fume hoods should not be used as a means of disposal of volatile chemicals.

g. Liquid organic wastes should be emptied into labeled plastic containers kept in vented metal cabinets in each laboratory.

h. Highly reactive wastes such as acid chlorides should be converted to a less reactive form before disposing in the waste containers.
 
 

b. Every effort should be made to avoid an unlabelled waste container. If such a container is discovered, the lab supervisor should attempt to determine the most likely contents of the container by interviewing appropriate people. The substance should be analyzed only if there is a high degree of certainty that this can be done without risk. If this cannot be done, the substance must be disposed of as an "unknown" at considerable cost to the University.
 
 

b. Each generator (lab) may accumulate no more than 55 gallons of hazardous waste or 1 quart of acutely hazardous waste.

c. The Code of Federal Regulations states that hazardous waste pick-ups are to occur within 90 days after the waste starts to accumulate (at the collection site) in order to avoid becoming a storage facility. All university departments and campus generators will be notified of the collection date so that wastes can be made available for pick-up.
 
 

b. A permit is received from the EPA for this disposal. The wastes are packed into fifty-five gallon drums in accordance with EPA and Department of Transportation specifications, detailing the types of wastes that may be packed together, types of packing material, and types and conditions of the drums. Labels must be affixed to the drums to indicate the types of waste contained within. Pertinent documentation is made by University personnel regarding the wastes being removed for disposal. The waste drums are then picked up by the outside firm who is responsible for transportation and the disposal of the wastes. The Wittenberg University Purchasing Department will schedule the pick-up date for the waste with an approved disposal contractor.

c. An annual written survey will be made by the Purchasing Department to determine the amount and kind of wastes to be disposed. The survey will include a definition of hazardous waste and examples of such materials. A written response will be attached to a copy of the survey request, and determination will be made of the need for disposal services based on the response.
