• INTRODUCTION• MANAGEMENT OF HAZARDOUS

MATERIALS • ENVIRONMENTAL MANAGEMENT ISSUES• SECURITY ISSUES



• INTRODUCTION – This presentation will cover the requirements for managing hazardous materials in the laboratory and university setting.

• This includes the use, handling, storage, and generation of hazardous waste.

• Finally, we will discuss security and unauthorized entries.



• ENVIRONMENTAL MANAGEMENT SYSTEM

• POLLUTION PREVENTION AND WASTE MINIMIZATION

• ENVIRONMENTAL TRAINING



• Each lab must develop as part of their chemical hygiene plan a standing operating procedure for management of hazardous materials in their labs. This is called an Environmental Management System.

• This System includes but is not limited to receiving, storing, and proper use of materials in each individual and unique lab.

• Also, the Standard Operating Procedures (SOP)/Chemical Hygiene Plan should include waste minimization, use of personal protective equipment, and environmental training. Environmental training includes waste labeling, storing, and responding to chemical spills.



SYSTEM• Policy

• Planning

• Implementation

• Quality Assurance and Control

• Health and Safety Policy Reviews



SYSTEM• The TU Office of Environmental Health and Safety

(OEHS) has developed policies and procedures for the management of hazardous materials and waste located at www.som.tulane.edu/oehs.

• These policies include the advanced planning of purchasing chemicals, storage, use, and disposal.

• The planning process should include the development of safety procedures, steps to ensure hazardous material control, and the review of university policies.

POLLUTION PREVENTION AND WASTE MINIMIZATION

• Waste Stream Assessment

• Reduce and Eliminate

• Substitute

• Recycle

• Treatment


POLLUTION PREVENTION AND WASTE MINIMIZATION

One of the goals of a Environmental Management System is to reduce the amount of hazardous waste that each generator produces. There are several ways in which hazardous waste can be reduced and/or eliminated:– Reduce by reducing size of experiments and/or research.– Try to achieve the same desired effects with minimal amounts of

chemicals being used. – Eliminate the use of hazardous materials in a particular step or

procedure. – Substitute to a less toxic material. – Reuse/recycle unused chemicals within a department. – Add a step to your experiment that will neutralize and detoxify the

hazardous material.


HAZARDOUS MATERIALS HANDLING AND STORAGE

• Only store compatibles together; consult the Material Safety Data Sheets (MSDS)

• Use approved flammable liquid storage cabinets for solvents

• Rotate inventory• Inspect ether and perchloric acid containers for

integrity and do not store past six months• Do not store hazardous materials behind doors or

near ignition sources such as open flames, ovens and oxidizing chemicals


HAZARDOUS WASTE CONTAINER MANAGEMENT



• Generators that store hazardous waste in containers must manage their containers in such a manner that they will not cause incidents involving hazardous materials.

• Eight simple steps outline the “Best Management Practices for Hazardous Waste Containers.”



1. Identify all hazardous wastes

2. Do not mix incompatible wastes (i.e., acids and bases, or solvents and radioactive wastes)

3. Put waste in compatible containers and containers that are in good condition

4. Label waste as “hazardous waste”



5. Remove any labels that were previously on the waste container

6. Keep container closed when you are not putting waste into it

7. Separate and/or put a barrier between incompatible waste (don’t store acids and bases together)

8. Dispose of hazardous waste in a timely manner; contact Hazardous Waste Supervisor for instructions per campus


MANAGEMENT OF HAZARDOUS WASTES

• ELEMENTARY NEUTRALIZATIONS

• RECYCLING

• TREATMENT OF WASTE– PRECIPITATION OF HEAVY METALS– OXIDATION/REDUCTION


MANAGEMENT OF HAZARDOUS WASTES

• Other management practices for hazardous waste include acid/base neutralizations, recycling chemicals to those who can use them throughout each campus and department, and basic oxidations/reductions to reduce toxicity of hazardous materials such as Ethidium Bromide.

• All neutralization and oxidation reactions must be reviewed by OEHS.

• Check with the Manager of Chemical Safety or the Hazardous Waste Supervisor for further information.


ENVIRONMENTAL TRAINING

• Required by Federal and State Regulations

• University Policy and Procedures

• Reduces incidents involving Hazardous Materials

• Saves lives and property

• Reduces personal liability


ENVIRONMENTAL TRAINING

• Anyone that uses hazardous materials and generates hazardous waste is required to receive environmental training under federal and state regulations.

• The training will help ensure that each employee understands and knows that policies and procedures have been written to address the use of hazardous materials in a university setting.

• Also, training helps reduce and/or eliminate incidents involving hazardous materials.

• Training helps save lives and property and reduces personal liability.


HAZARDOUS WASTE ISSUES

• WATER DISCHARGES• HAZARDOUS WASTE• NON-HAZARDOUS WASTE• BIOLOGICAL AND MEDICAL WASTE• RADIOACTIVE WASTE• HAZARDOUS MATERIAL SPILLS• HAZARDOUS MATERIALS HANDLING AND

STORAGE


HAZARDOUS WASTE ISSUES• There are many types of hazardous wastes that are

generated.

• Each generator must assess the different types of waste streams (categories of waste) that is generated.

• Also, when assessing the waste streams, each generator should also develop a spill response procedure for each type of hazardous material they use, store, and handle.

• Users should consult MSDS on storage recommendations for hazardous materials.

• Do not store according to alphabetical order, this may not be compatible order. Store according to hazard.


WATER DISCHARGE ISSUES

• Mixing of Hazardous Materials with cooling water

• Discharging wastewater into sewer systems

• Discharging hazardous materials into drainage systems


WATER DISCHARGE

• If you use water in your experiments to cool and/or condensate, ensure that all connecting tubes are secured to prevent mixing with chemicals.

• Do not dilute; “Dilution is not the Solution” to hazardous materials disposal.


HAZARDOUS WASTE ISSUES

• Proper labeling of hazardous waste• Proper storage of hazardous waste• Mixing of non-compatibles• Closed containers when not adding waste• Dispose of waste in timely manner


HAZARDOUS WASTE• All hazardous waste that is generated at the university must be

properly labeled according to federal and state regulations.

• All waste must be labeled with the words, “ Hazardous Waste” and each waste must be identified. For example, acid waste must be identified as, hydrochloric, sulfuric, nitric, etc. DO NOT label the container as “ ACID WASTE.”

• Also, waste must be properly stored, not on floors, behind doors, not in incompatible containers and with other materials that will cause a reaction.

• All containers must remain capped and closed when not adding waste to the containers.

• Generated waste in each work area must be disposed within 30 days of generation. Contact Hazardous Waste Supervisor at [email protected] or call 504-988-2865.

HAZARDOUS WASTE

• Improper storage of hazardous waste; waste was abandoned in lab. If researcher is leaving the university, he/she must fill out a laboratory close-out form located at the OEHS website.


HAZARDOUS WASTE

Abandoned and unlabeled hazardous waste


Improper storage of hazardous materials and waste. Fume hood is cluttered, paper products are located with materials that can cause a reaction. There is evidence of a hazardous material spill within the hood.


• Improper storage of materials in a refrigerator and unlabeled containers


Cluttered fume hood, spilled hazardous materials, unlabeled and improperly labeled containers


Improperly stored hazardous materials have caused a reaction to the plumbing of the lab sink.


HAZARDOUS WASTE• Hazardous Waste

Improperly Labeled and Stored


WASTE DISPOSAL POLICIES TNPRC

• There are special procedures for rinsing glassware and hazardous materials containers at TNPRC.

• Procedures are designed to comply with local, state and federal regulations concerning TNPRC on-site treatment facilities.

• Procedures ensure that no hazardous materials are disposed via the sewer disposal systems


TNPRC PROCEDURES

• Hazardous materials are not to be disposed via the solid waste or sewer disposal systems. This includes but is not limited to toxic, flammable, corrosive, reactive and radioactive materials.

• All containers that previously contained hazardous materials must be rinsed, and the first rinse must be collected and then disposed as hazardous waste.


TNPRC PROCEDURES

• For laboratory glassware that is cleaned with water, the first rinse water must be collected as hazardous waste and placed in a compatible hazardous waste container.

• Empty containers that have been rinsed can be disposed as non-hazardous waste.

• All hazardous wastes are to be labeled, containerized and closed unless waste is being added to the container.


NON-HAZARDOUS WASTE ISSUES

• Empty Containers

• Paper Products and Packaging

• Used Personal Protective Equipment (PPE)

• Broken Glass and Pipettes


NON-HAZARDOUS WASTE ISSUES

• Materials that are not considered hazardous waste must be disposed as solid waste.

• Empty containers must have the labels defaced or removed.

• Paper products that are not saturated with hazardous materials and/or biomedical waste can be disposed as non-hazardous waste.

• Broken glass and pipettes must be placed in a broken glass rigid disposal container.


BIOLOGICAL AND MEDICAL WASTE

• Containers or glassware contaminated with biological hazards must be placed in an approved medical waste disposal container. These must be clearly marked as “ Medical Waste” and with the international biohazard symbol.

• Sharps (syringes, scalpels, blades) must be placed in a sharps container. DO NOT place in plastic bags, cardboard boxes, metal cans and/or old paint cans.


BIOLOGICAL AND MEDICAL WASTE

Blood, blood products, viruses, body fluids, and potential pathogenic materials are considered Biomedical Waste and must be disposed by an approved medical waste disposal company.


RADIOACTIVE WASTE

• Radioisotope Disposal

• Licenses

• Scintillation Solvents

• For radioisotope disposal, contact Charles Reindl, Radiation Safety Officer at 504-988-2867.


HAZARDOUS MATERIAL SPILLS

• Prevention

• Preparation

• Spill Occurrence

• Spill Containment

• Post-Spill Activities



• Incidents involving hazardous materials do occur. A well, carefully written plan to respond to these incidents must be developed for your work area.

• Everyone that handles, uses and stores hazardous materials must have “ Spill Response Training.”

• The best way to respond to an incident involving hazardous materials is to prevent it from happening.

• Proper handling, storing and using will prevent spills from occurring.



• Notify others in the immediate area of the spill• Secure area (i.e., close door, pull fume hood sash

down)• Activate fire alarm if a fire occurs• Contact Tulane Police• Contact OEHS for notification & further

instructions



Each work area should have a small spill response kit.

This kit should include chemical absorbent pads, gloves, goggles and/or safety glasses, and neutralizing materials.

Consult the MSDS on proper clean up and absorbing materials for each chemical you use.


Mercury Spills

• Contain the spilled materials• Put on protective clothing such as gloves and

disposable gowns.• Absorb with an approved absorbent• Clean up the absorbed material and place it in an

enclosed container.• Label the container as Hazardous Waste/Mercury• Contact OEHS for notification & disposal


Mercury Spills• Small broken thermometers can be contained in a

small jar and/or beaker. • Use Mercury Spill Kits for small spills (less than 8

oz). • Large spills from equipment and instrumentation

must be reported to OEHS. Mercury breaks into small beads and these can spread and are hard to see and detect.

• OEHS has a special mercury vacuum pump for spill cleanup and a survey instrument to measure the level of mercury in the ambient air.


Security of Hazardous Materials

• Security Guidelines

• Chemical and Biological Agents

• Summary


Security of Hazardous Materials

• EPA and Homeland Security regulations require facilities to develop security measures for the storage and use of hazardous materials.

• Each area must assess the potential hazards of the chemical and biological materials.

• If you use Select Agents, contact the TU Biosafety Officer .


PURPOSE

• Work area supervisors need to take specific actions in order to provide security against theft of highly hazardous materials.


Security Guidelines

• Recognize that security is related to but different from safety.

• Develop a site-specific security policy• Control access to areas where hazardous materials

are stored• Know who is in the area• Secure highly hazardous materials• Have an emergency plan• Take precautions, know what is in your area and

who belongs there!


Chemical and Biological Agents

• List highly hazardous and biological materials on Chemical Hygiene Plans and inventories

• Follow recommended safety guidelines by Centers for Disease Control (CDC)


Chemical and Biological Agents• If biological and select agents are stored in your

work area, you must have approval from the TU Biosafety Officer.

• Storage, use, handling and disposal of these materials have specific regulations and guidelines for shipping, receiving, use and disposal.

• For further information, contact the Biosafety Officer.


Summary – Security Issues• Look out for these important areas of concern:

– Unlocked labs and other work areas

– Unrestricted areas

– Unlocked support areas

– Toxic gas security

– Biological materials not secured

– Substantial changes in inventory

– Storeroom security


Summary

• Pre-plan

• Minimize waste

• Store and handle hazardous materials properly

• Properly manage and use hazardous waste containers

• Provide training of personnelTulane University - Office of Environmental Health & Safety (OEHS)

SUMMARY

• Be familiar with the following:– Proper labeling and storage of hazardous waste– DO NOT mix incompatible chemicals– Close containers when not adding waste– Dispose of waste in timely manner
