Proper Waste Disposal

1. Waste Management
<ol>
	<li>Users should make an effort to keep waste to a minimum. The best way to do so is by reducing the scale of operation, which minimizes the quantity of waste generated. Whenever possible, chemicals used should be substituted with less hazardous chemicals.</li>
	<li>Chemical quantities should be kept to a minimum. Store only what will be used in the near term.</li>
	<li>Besides preventing or minimizing waste generation, chemicals should be recycled or recovered for reuse.</li>
	<li>When waste is generated, it must be disposed of properly. Sink disposal may not always be appropriate and may end contaminating drinking water. Alternative methods of disposal should be considered including incineration, treatment, and land disposal. The institute&#39;s EHS office should be consulted to determine the proper disposal method for different waste types.</li>
</ol>
2. Waste Collection and Storage
<ol>
	<li>When generating or managing any chemical waste, appropriate personal protective equipment (PPE) must be worn, and engineering controls should be implemented as necessary.</li>
	<li>Collect and store chemical waste at or near the point of generation in a designated satellite accumulation area. This accumulation area should be well marked for easy identification.</li>
	<li>Chemical waste must be stored in compatible containers with closed and properly fitted caps.</li>
	<li>Waste containers must be labeled mentioning chemical compositions, the accumulation start date, and hazard warnings as appropriate. The institute&#39;s EHS office typically provides these required labels.</li>
	<li>Incompatible waste types should not be mixed and should be kept separate in order to avoid any reaction, heat generation, and/or gas evolution.</li>
	<li>Waste containers should be stored in secondary containers in a ventilated, cool, and dry area.</li>
	<li>In the central accumulation area, waste containers should be grounded to avoid fire and explosion hazards.</li>
	<li>Trained laboratory researchers who are most familiar with the waste generated should work with EHS to ensure proper waste management.</li>
</ol>
3. Sharps Disposal - Syringes and Needles
<ol>
	<li>Chemically contaminated needles, syringes, and razor blades should be disposed of inside a proper sharps container.</li>
	<li>Syringes or needles must never be disposed of in a laboratory waste bin or a general waste container.</li>
</ol>
4. Glass Recycling
<ol>
	<li>Recycling glass is friendly to the environment as it reduces pollution caused by the waste ending up in landfill sites. Every laboratory should have a separate recycling bin dedicated to glass.</li>
	<li>Clean empty glass bottles and broken glassware may be recycled. To clean an empty glass bottle, it must be &#34;triple rinsed&#34; with water or another suitable solvent and air-dried before disposal.</li>
	<li>Chemically contaminated laboratory glassware such as sample tubes, droppers, and glass wool must be disposed of as controlled waste.</li>
</ol>

proper waste disposal

Robert M. Rioux and Taslima A. Zaman, Pennsylvania State University, Pennsylvania, PA

Users are responsible for the proper disposal of the waste generated during their work. Improper waste disposal may severely endanger public health and/or the environment. The handling of hazardous waste must be regulated from the moment of generation until its disposal at its offsite final destination facility. A waste management system must be devised before work begins on any laboratory activity. Users must comply with the rules and regulations of their institute&#39;s Environmental Health and Safety (EHS) office, which develops and implements proper waste management systems satisfying diverse regulations and standards, such as those imposed by the Occupational Safety and Health Administration (OSHA).

Users are responsible for the proper disposal of the waste ...

Hazardous waste, whether chemical, medical or radioactive, is generated in many laboratories and requires regulated disposal to ensure safety of public health and the environment.The regulation of hazardous waste handling must be enforced from the moment of generation until its disposal at an offsite final destination facility.Prior to commencing any laboratory activity, a waste management system must be devised. This is often established by an institute's Environmental Health and Safety, or EH&S, office, which enforces guidelines imposed by the Occupational Safety and Health Administration, or OSHA.This video will illustrate the principles and typical laboratory procedures of proper waste disposal.Efficient waste management is an important aspect of proper waste disposal. This can be accomplished by using the minimal amount of chemicals possible, by reusing surplus materials, and by recycling waste.The generated waste must be labeled, segregated according to chemical compatibility, and stored in a fume hood or other well ventilated area. Other laboratory waste, such as sharps and glass, must be disposed with care in appropriate containers.Now that we have discussed the principles of proper waste disposal, let's look at an actual procedure.If applicable, keep chemical waste to a minimum by reducing the scale of operation. Furthermore, substitute chemicals with less hazardous reagents whenever possible.In addition to minimizing the scale of operation, store only chemical quantities that will be used in the near term. You can also reduce chemical waste by recycling solvents like acetone, using a distillation.Wear proper personal protective equipment including a lab coat, goggles, and gloves, as well as long pants and closed-toed shoes, whenever handling any chemical waste.Collect chemical waste in suitable containers such as plastic carboys or glass bottles, and store near the point of generation in a designated satellite accumulation area.Affix labels to the waste containers as soon as chemicals are added. Write on the labels the full names of the chemicals and their approximate compositions.Additionally, use separate containers for halogenated, nonhalogenated, and aqueous waste to avoid potential heat or gas formation. When the containers are filled to capacity, carefully move them to a designated central accumulation area, from which they will be removed for disposal.Dispose of chemically contaminated needles, syringes and razor blades, collectively known as sharps, inside of a sharps waste container.For broken glass, used pipettes or test tubes, use a specialized glass waste container. If desired, empty bottles can be reused after triple rising with acetone, water, and again acetone.You've just watched JoVE's introduction to proper waste disposal. You should now understand waste management, how to collect chemical and sharps waste, and how to store it for disposal. Thanks for watching!

Lab Safety

lab waste management and safety

Lab waste management and safety are essential parts of any laboratory activity. Waste generated during work must be handled correctly from the moment it is created until it reaches its final offsite disposal facility. Poor waste disposal can seriously harm public health and the environment.

A waste management system should be planned before any lab work begins. This system guides how waste is collected, stored, and prepared for removal. For hazardous waste, special rules apply because its handling must be regulated throughout the entire process.

Students and lab users must also follow their institution’s Environmental Health and Safety, or EHS, office. The EHS office develops and carries out waste management systems that meet different rules and standards. These include requirements set by the Occupational Safety and Health Administration, or OSHA.

Lab Waste Management and Safety

proper personal protective equipment

Choosing the Right Lab PPE

Choosing the right lab PPE is a key part of working safely in a laboratory. PPE, or personal protective equipment, helps reduce risk when hazards are present. Laboratory hazards can be many and varied. The right choice of PPE helps make the lab a safe place to work. Students should match their protective gear to the tasks and conditions in the lab. This topic focuses on selecting proper protection for the situation at hand. Wearing the correct PPE supports safer lab work and helps limit...

emergency eyewash and shower stations

Laboratory Chemical Spill Response Stations

Laboratory chemical spill response stations help protect people who are exposed to injurious or corrosive substances. In workplaces and school labs, OSHA requires emergency eyewash and shower stations to be easy to reach when these hazards are present. These stations are used after an accident that spills a harmful chemical on the body or splashes it into the eyes. The eyewash station helps rinse the eyes, while the shower station is used for chemicals on the skin or clothing. They are meant...

electrical safety

Preventing Lab Electric Shock and Fires

Electrical hazards are a common lab safety concern. Most laboratory equipment uses electricity to work, so students and lab staff must stay alert around cords, plugs, and powered devices. Improper use of electrical equipment can cause electric shock. In serious cases, this can lead to injury or death. Electrical sparks are also dangerous in the lab. They can start a fire or trigger an explosion. This risk matters because many flammable chemicals may be stored near powered instruments. Knowing...

working with centrifuges

Centrifuge Safety and Sample Separation

Centrifuges are used to separate heterogeneous mixtures by spinning particles in a fluid at high speed. The motion creates a force away from the axis of rotation. Heavier particles move faster toward the bottom of the sample holder, and the rate depends on particle size and density. This process is called centrifugation, and it speeds up sedimentation, which is the settling of particles out of a liquid. Gravity can separate some mixtures on its own, but that can take a long time.

working with hot and cold sources

Safe Use of Lab Heat and Cold Sources

Safe use of lab heat and cold sources is an important part of laboratory work. Extreme temperatures are common in many lab tasks. They can involve both high heat and very low temperatures. Bunsen burners and hot plates are widely used in research labs and industry. A Bunsen burner is a gas burner that gives a direct flame. A hot plate is an electric device that warms containers without an open flame. Because these tools reach high temperatures, users need to follow safe handling procedures. <br...

Safe Chemical Labels and Storage Basics

Safe chemical storage and labeling help prevent dangerous reactions in school and research labs. Chemicals can vary widely in their properties and reactivity, so they must be managed, stored, and labeled correctly as part of an Environmental, Health and Safety (EHS) program. If chemicals are not handled properly, they can create harmful or even destructive results. These risks include toxic fume production, fire, explosion, human fatality, property damage, and environmental hazards. Proper...

safe handling of mineral acids

Mineral Acids in the Lab

Mineral acids are common chemicals in research laboratories, and they must be handled with care. These acids, also called inorganic acids, are water-soluble acids formed from inorganic minerals by chemical reaction. Their corrosive nature makes them a major safety risk in the lab. Examples of mineral acids include boric acid, chromic acid, hydrochloric acid, hydrofluoric acid, nitric acid, perchloric acid, phosphoric acid, and sulfuric acid. These acids are important reagents in research, and...

handling chemical spills

Chemical Spill Safety in the Lab

Chemical spill safety in the lab is essential whenever hazardous chemicals are used. Spills can happen at any time during laboratory work. Even a small spill can become dangerous if people are not prepared to respond quickly and correctly. Preparing for a chemical spill helps protect public health and the environment. Lab teams need to know how to respond to accidental releases of hazardous chemicals before an emergency happens. Safe cleanup also depends on proper disposal of the spilled...

proper use of autoclaves

Autoclaving Lab Materials Safely

Autoclaving lab materials safely is an important part of decontamination in the laboratory. This method is commonly used for items that have contacted biological samples, especially those that may contain microorganisms. An autoclave cleans materials with pressurized steam at a high temperature. The steam and heat work together to kill microorganisms on the loaded items. For this reason, effective autoclaving depends on good steam flow and strong heat transfer. Packaging matters because it...

fume hoods and laminar flow cabinets

Airflow Controls for Safer Lab Workspaces

Fume hoods and laminar flow cabinets are airflow controls used in laboratories. They both rely on a constant stream of air to protect the lab environment and the people in it. These systems work in similar ways, but they serve different purposes. A fume hood is a ventilation system that helps reduce exposure to hazardous vapors, fumes, and particles. Air is drawn into the hood opening, which helps keep harmful substances inside the workspace. The air is then pulled out through the exhaust. A...

Schlenk Line Setup for Inert Atmospheres

A Schlenk line helps chemists work with air- and water-sensitive chemicals. It provides an air-free way to handle reagents that can react with oxygen or moisture. This makes it useful in a chemical laboratory when careful control of the atmosphere is needed. The glass apparatus is commonly used because it can create an inert gas environment or a vacuum. Inert gases such as nitrogen and argon can be used to protect the reaction. The same setup can also expose glassware to vacuum when needed. A...

proper operation of vacuum based equipment

proper-operation-of-vacuum-based-equipment

Vacuum Pumps for Laboratory Procedures

Vacuum pumps are used in many laboratory procedures that need low pressure. They help create vacuum conditions for experiments and equipment that must run below normal atmospheric pressure. In the lab, vacuum pumps are the most common way to achieve this low-pressure environment. They can also support rapid changes in the atmosphere inside a reactor or flask. This is done by evacuating the vessel and then backfilling it with another gas.

operating the glovebox

Glovebox Atmosphere and Sample Transfer

A glovebox is an enclosed workspace that keeps an inert atmosphere inside. Scientists use built-in gloves to handle chemicals or equipment without exposing the inside of the box to outside air. The box uses positive pressure to help make up for small passive leaks. Objects can be moved in and out through an antechamber, which works like an airlock between the glovebox and the outside atmosphere. Some gloveboxes have more than one pair of gloves. The number of glove ports depends on the size...

operation of high-pressure reactor vessels

operation-of-high-pressure-reactor-vessels

Safe Use of Pressure Vessels in Chemistry

High-pressure reactor vessels are used in synthetic chemistry to handle gases safely during reactions. They help chemists carry out gas-based processes such as hydrogenation, oxidation, and amination. These reactions often use hydrogen, oxygen, or ammonia, which are important reagents in the lab. These gases usually dissolve poorly in standard reaction mixtures. Because of that, high pressure is needed to make the reaction proceed at a useful rate. The vessel creates a sealed space that keeps...

decontamination for laboratory biosafety

Lab Cleaning Methods for Biosafety

Laboratory cleaning methods are a key part of biosafety because microbial contamination can build up and spread disease. Decontamination is used to reduce that risk on lab surfaces and equipment. The level of cleaning depends on how much contamination is present and what kind of item needs treatment. Decontamination can be grouped into disinfection and sterilization. Disinfection removes pathogenic microorganisms, but it does not remove bacterial spores on lab surfaces or equipment.

Lab waste management and safety are essential parts of any laboratory activity. Waste generated during work must be handled correctly from the moment it is created until it reaches its final offsite disposal facility. Poor waste disposal can seriously harm public health and the environment. A waste management system should be planned before any lab work begins. This system guides how waste is collected, stored, and prepared for removal. For hazardous waste, special rules apply because its...
