Chemical Management Procedures

1.0 PURPOSE:

Hazardous and nonhazardous chemical are generated by a variety of activities at LSUHSC. Proper handling and disposal of hazardous chemical wastes reduces the threat to human health and the environment.

2.0 SCOPE:

These procedures provide guidance to all LSUHSC personnel who generate and handle hazardous and nonhazardous chemical waste.

3.0 RESPONSIBILITIES:

Environmental Health and Safety Department (EHS) shall: • Develop and implement procedures for the proper handling and safe disposal of hazardous chemical waste. • Provide safe storage of hazardous chemical waste pending disposition. • Comply with all government regulations regarding management. • Prepare, submit, and maintain all records, reports, and manifests as required by government regulations.

Principal Investigators and Supervisors shall: • Ensure their personnel are trained on and follow these procedures. • Determine if the chemical waste they generate is hazardous or nonhazardous and identify the appropriate route of disposal. • Develop and implement more stringent procedures following the identification of any specific risks relevant to the handling and disposal of hazardous chemical waste.

Employees shall: • Comply with these guidelines. • Notify the EHS Department in the event of any spills.

4.0 IMPLEMENTATION

This section provides guidance on the procedures for collecting, labeling, and pick-up information for chemical waste.

Separation When collecting chemical waste for disposal: • Compatible waste streams may be collected in one container. • Never mix incompatible wastes (e.g., and bases). • Segregate wastes containing heavy from other types of waste. • Place batteries separately in plastic bags or cardboard boxes for collection. Cover battery terminals with tape if not placed in individual plastic bags.

Disposal Containers • Do not use containers with capacities exceeding one gallon unless granted written permission from the EHS Department. • Only use containers that are in good condition, have tight fitting lids, and are compatible with the type of waste stored. • The chemical’s original container can be used for disposal if it is not damaged and can be securely resealed; however, do not the original container if the waste’s physical characteristics have been significantly changed. For example, if a flammable has also been made corrosive by the addition of an , than a container would no longer be suitable for this waste. • Do not place hazardous waste in an unwashed container that previously held an incompatible material. • Do not overfill a container; always leave an at least a two inch air gap. • Always keep the storage container closed during storage; never leave a waste container sitting open with a funnel in it. Labeling Label all hazardous chemical waste containers with the following: • The words “HAZARDOUS WASTE”. • The principle chemical constituents and the approximate percentages. • The date that waste was first placed in the container.

Chemical Waste and Battery Pick-up Information Chemical waste pick-ups are a service provided by the EHS Department. Chemical waste pick-ups are held weekly on Thursdays; a service request must be submitted for every chemical waste pick-up. Authorized individuals must use the bob.lushsc.edu service request system. To have a chemical waste pick-up done by Thursday, submit a service request no later than Wednesday at 4:00 p.m.

5.0 TRAINING

All EHS personnel who handle hazardous chemical waste must complete 40 hour Hazardous Waste Operations and Emergency Response Standard (HAZWOPER) training and annual HAZWOPER refresher training.

6.0 WASTE CLASSIFICATIONS

• Acute Waste is waste that can be lethal to humans or significantly contribute to an increase in serious irreversible or incapacitating illness.

• Hazardous waste waste materials are identified by the Environmental Protection Agency, (EPA) and the Louisiana Department of Environmental Quality (LDEQ) as being hazardous waste either by being listed by chemical names or by having certain physical and chemical characteristics. The “listed chemicals” can be found in the Louisiana Administrative Code 33 Volume 4901 and the characteristic categories are found in the Louisiana Administrative Code 33 Volume 4903.

There are four categories of “listed chemicals”: o Acute hazardous waste (P list) o Toxic waste (U list) o Non-specific source waste (F list) – this list is made up of spent halogenated and non-halogenated o Specific sources (K list) – this list is primarily industrial processes.

All hazardous chemicals that are not categorized as a listed chemical and have characteristic properties that cause it to pose a sufficient threat to people or the environment must be managed as a hazardous chemical. The four characteristics identified by the EPA and LDEQ are: o Ignitability o Corrosivity o Reactivity o

Ignitable Characteristic Waste o Is a with a flash point less than 140°F (60 degrees Centigrade) o Is not a liquid and capable under normal conditions of causing fire through friction, absorption of moisture or spontaneous chemical changes o Is an ignitable compressed o Is an oxidizer

Corrosive Characteristic Waste o Is aqueous and has a pH less than or equal to 2 or greater than or equal to 12.5. o Is a liquid and corrodes steel at a rate greater than or equal to 6.35 mm (1/2 inch) per year at a temperature of 55°C (130°F).

Reactivity Characteristic Waste o Is normally unstable o Reacts violently with water o Forms potentially explosive mixtures with water o Generates toxic , or fumes when mixed with water o or sulfide wastes that generate toxic gases, vapors or fumes under basic or acidic conditions o Capable of detonation or explosive decomposition if subjected to strong initiating source or if heated under confinement o Capable of detonation, explosive decomposition or reaction at standard temperature and pressure

Toxicity Characteristic Waste The following is a list of the maximum concentrations of a materials allowed in a waste after a specified procedure has been performed. Any waste with a concentration below what is listed is not considered hazardous: Toxicity Contaminant Maximum Concentration (mg/l) Arsenic 5.0 Barium 100 .0 Benzene 0.5 Cadmium 1.0 Carbon Tetrachloride 0.5 Chlordane 0.03 Chlorobenzene 100.0 Chloroform 6.0 Chromium 5.0 O-Cresol 200.0 m-Cresol 200.0 p-Cresol 200.0 Cresol 200.0 Dichlorobenzene 1, 4 7.5 Dichloroethane 1, 2 0.5 Dichlorethylene 1, 1 0.7 Dinitrotoluene 2, 4 0.13 2, 4 D 10.0
