Proper Waste Disposal

1. Gestione dei rifiuti
<ol><li>Gli utenti dovrebbero fare uno sforzo per mantenere gli sprechi al minimo. Il modo migliore per farlo è ridurre la scala di funzionamento, che riduce al minimo la quantità di rifiuti generati. Quando possibile, le sostanze chimiche utilizzate dovrebbero essere sostituite con sostanze chimiche meno pericolose.</li>
	<li>Le quantità chimiche dovrebbero essere ridotte al minimo. Memorizza solo ciò che verrà utilizzato a breve termine.</li>
	<li>Oltre a prevenire o ridurre al minimo la produzione di rifiuti, le sostanze chimiche dovrebbero essere riciclate o recuperate per il riutilizzo.</li>
	<li>Quando i rifiuti vengono generati, devono essere smaltiti correttamente. Lo smaltimento del lavandino potrebbe non essere sempre appropriato e potrebbe porre fine alla contaminazione dell'acqua potabile. Dovrebbero essere presi in considerazione metodi alternativi di smaltimento, tra cui l'incenerimento, il trattamento e lo smaltimento dei terreni. L'ufficio EHS dell'istituto dovrebbe essere consultato per determinare il metodo di smaltimento corretto per i diversi tipi di rifiuti.</li>
</ol>2. Raccolta e stoccaggio dei rifiuti
<ol><li>Quando si generano o si gestiscono rifiuti chimici, devono essere indossati adeguati dispositivi di protezione individuale (DPI) e, se necessario, devono essere attuati controlli tecnici.</li>
	<li>Raccogliere e immagazzinare i rifiuti chimici presso o vicino al punto di generazione in un'area di accumulo satellitare designata. Questa area di accumulo dovrebbe essere ben contrassegnata per una facile identificazione.</li>
	<li>I rifiuti chimici devono essere conservati in contenitori compatibili con tappi chiusi e correttamente montati.</li>
	<li>I contenitori dei rifiuti devono essere etichettati indicando le composizioni chimiche, la data di inizio dell'accumulo e le avvertenze di pericolo, a seconda dei casi. L'ufficio EHS dell'istituto in genere fornisce queste etichette richieste.</li>
	<li>I tipi di rifiuti incompatibili non devono essere miscelati e devono essere tenuti separati per evitare qualsiasi reazione, generazione di calore e/o evoluzione del gas.</li>
	<li>I contenitori per i rifiuti devono essere conservati in contenitori secondari in un'area ventilata, fresca e asciutta.</li>
	<li>Nell'area centrale di accumulo, i contenitori dei rifiuti devono essere messi a terra per evitare rischi di incendio ed esplosione.</li>
	<li>I ricercatori di laboratorio addestrati che hanno più familiarità con i rifiuti generati dovrebbero lavorare con EHS per garantire una corretta gestione dei rifiuti.</li>
</ol>3. Smaltimento di taglienti - Siringhe e aghi
<ol><li>Aghi, siringhe e lamette da rasoio contaminati chimicamente devono essere smaltiti all'interno di un contenitore di taglienti adeguato.</li>
	<li>Le siringhe o gli aghi non devono mai essere smaltiti in un cestino dei rifiuti di laboratorio o in un contenitore per rifiuti generici.</li>
</ol>4. Riciclaggio del vetro
<ol><li>Riciclare il vetro è rispettoso dell'ambiente in quanto riduce l'inquinamento causato dai rifiuti che finiscono nelle discariche. Ogni laboratorio dovrebbe avere un cestino separato dedicato al vetro.</li>
	<li>Bottiglie di vetro vuote pulite e bicchieri rotti possono essere riciclati. Per pulire una bottiglia di vetro vuota, deve essere "triplo risciacquata" con acqua o un altro solvente adatto e asciugata all'aria prima dello smaltimento.</li>
	<li>Gli oggetti di vetro da laboratorio contaminati chimicamente come tubi campione, contagocce e lana di vetro devono essere smaltiti come rifiuti controllati.</li>
</ol>

In questo documento viene fornita una linea guida di base per lo smaltimento dei rifiuti di laboratorio. Gli utenti devono lavorare e rispettare l'ufficio EHS del loro istituto per determinare il metodo corretto per lo smaltimento dei rifiuti che soddisfi diverse normative e standard. L'utente del laboratorio dovrebbe essere consapevole di quale materiale di scarto viene generato e i pericoli presenti dovrebbero essere attentamente valutati per determinare il corretto smaltimento dei rifiuti, che potrebbe altrimenti mett...

corretto smaltimento dei rifiuti

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

Gli utenti sono responsabili del corretto smaltimento dei rifiuti generati durante il loro lavoro. Lo smaltimento improprio dei rifiuti può mettere gravemente in pericolo la salute pubblica e/o l'ambiente. La gestione dei rifiuti pericolosi deve essere regolamentata dal momento della generazione fino al loro smaltimento presso il suo impianto di destinazione finale fuori sede. Un sistema di gestione dei rifiuti deve essere ideato prima dell'inizio dei lavori su qualsiasi attività di laboratorio. Gli utenti devono rispettare le norme e i regolamenti dell'ufficio per la salute e la sicurezza ambientale (EHS) del loro istituto, che sviluppa e implementa adeguati sistemi di gestione dei rifiuti che soddisfano diverse normative e standard, come quelli imposti dall'Amministrazione per la sicurezza e la salute sul lavoro (OSHA).

Corretto smaltimento dei rifiuti

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

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

I rifiuti pericolosi, chimici, medici o radioattivi, vengono generati in molti laboratori e richiedono uno smaltimento regolamentato per garantire la sicurezza della salute pubblica e dell'ambiente. La regolamentazione della gestione dei rifiuti pericolosi deve essere applicata dal momento della produzione fino al loro smaltimento in un impianto di destinazione finale fuori sito. Prima di iniziare qualsiasi attività di laboratorio, è necessario elaborare un sistema di gestione dei rifiuti. Questo è spesso stabilito dall'ufficio per la salute e la sicurezza ambientale di un istituto, o EH&S, che applica le linee guida imposte dall'Occupational Safety and Health Administration, o OSHA. In questo video verranno illustrati i principi e le procedure tipiche di laboratorio per un corretto smaltimento dei rifiuti. Una gestione efficiente dei rifiuti è un aspetto importante del corretto smaltimento dei rifiuti. Ciò può essere ottenuto utilizzando la minor quantità possibile di sostanze chimiche, riutilizzando i materiali in eccesso e riciclando i rifiuti. I rifiuti generati devono essere etichettati, separati in base alla compatibilità chimica e stoccati in una cappa aspirante o in un'altra area ben ventilata. Altri rifiuti di laboratorio, come oggetti taglienti e vetro, devono essere smaltiti con cura in contenitori adeguati. Ora che abbiamo discusso i principi di un corretto smaltimento dei rifiuti, diamo un'occhiata a una procedura vera e propria. Se applicabile, ridurre al minimo i rifiuti chimici riducendo la portata del funzionamento. Inoltre, sostituire le sostanze chimiche con reagenti meno pericolosi quando possibile. Oltre a ridurre al minimo la scala di funzionamento, immagazzinare solo le quantità di sostanze chimiche che verranno utilizzate a breve termine. È inoltre possibile ridurre i rifiuti chimici riciclando solventi come l'acetone, utilizzando una distillazione. Indossare dispositivi di protezione individuale adeguati, tra cui camice da laboratorio, occhiali e guanti, nonché pantaloni lunghi e scarpe chiuse, ogni volta che si maneggiano rifiuti chimici. Raccogliere i rifiuti chimici in contenitori adeguati come damigiane di plastica o bottiglie di vetro e conservarli vicino al punto di generazione in un'area di accumulo satellite designata. Applicare le etichette sui contenitori dei rifiuti non appena vengono aggiunte sostanze chimiche. Scrivi sulle etichette i nomi completi delle sostanze chimiche e la loro composizione approssimativa. Inoltre, utilizzare contenitori separati per rifiuti alogenati, non alogenati e acquosi per evitare la potenziale formazione di calore o gas. Quando i contenitori sono pieni fino alla capacità, spostarli con cautela in un'area di accumulo centrale designata, da cui verranno rimossi per lo smaltimento. Smaltire aghi, siringhe e lame di rasoio chimicamente contaminati, noti collettivamente come oggetti taglienti, all'interno di un contenitore per rifiuti taglienti. Per vetri rotti, pipette o provette usate, utilizzare un contenitore per rifiuti in vetro specializzato. Se lo si desidera, le bottiglie vuote possono essere riutilizzate dopo una tripla lievitazione con acetone, acqua e di nuovo acetone. Hai appena visto l'introduzione di JoVE al corretto smaltimento dei rifiuti. Ora dovresti capire la gestione dei rifiuti, come raccogliere i rifiuti chimici e taglienti e come conservarli per lo smaltimento. Grazie per l'attenzione!

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.
