Proper Personal Protective Equipment

1. PPE mínimo <ol><li>al entrar en un laboratorio, un mínimo de PPE debe usarse. Esto incluye lentes de seguridad (discutidos más adelante), pantalones largos y zapatos cerrados. Esto proporciona una protección básica de los riesgos generales en el laboratorio. Además, cabello largo debe estar atado detrás y colgando joyas no se debe usar.</li>
</ol> 2. Guantes <ol><li>manos son a menudo el cuerpo partes más cercano a los peligros en el laboratorio. Guantes por lo tanto son una parte esencial de los EPI adecuado. Sin embargo, puede no siempre ser inmediatamente obvio que guantes son adecuados para la tarea que están llevando a cabo. Una evaluación de riesgo de la tarea puede ayudar a determinar el correcto par de guantes para usar. La evaluación de riesgos debe considerar lo siguiente: <ol><li>producto químico: la naturaleza química de la substancia es muy importante en la elección de los guantes apropiados. Materiales comunes para Guantes químicamente resistentes incluyen goma de butilo, látex, neopreno, nitrilo, polietileno, alcohol de polivinilo y cloruro de polivinilo. La elección del material adecuado puede a menudo hacerse fácilmente consultando una tabla de compatibilidad química (Ansell Occupational Healthcare, 2008). Ningún material es 100% resistentes a un químico. Un producto químico impregnan todos los materiales, a diferentes velocidades. Cuando consulta una tabla de compatibilidad química del guante, cabe señalar el tiempo de avance. Este es el tiempo que tarda una sustancia química totalmente viajar a través de un guante no utilizado inicialmente. Guantes deben cambiarse en consecuencia cuando se trabaja por períodos mayores que el tiempo avance. Si un guante se rompe o es pinchado, el guante debe ser retirado y reemplazado inmediatamente. Agujeros en el guante permiten penetración directa de los productos químicos a través del guante, haciendo que el guante sea ineficaz.</li>
		<li>Física: peligros físicos pueden incluir temperaturas criogénicas o elevadas, sostenidos y fuerzas mecánicas.</li>
		<li>Criogénico temperaturas: temperaturas criogénicas, Guantes criogénicos son adecuados. Guantes criogénicos de muñeca a hombro longitud de la gama y se hacen a menudo de una superficie exterior de nylon y poliéster superficie interna. La longitud debe ser elegida en base a otras evaluaciones de la tarea. Manejo de nitrógeno líquido es una ruta común de la exposición a temperaturas criogénicas de.</li>
		<li>Elevadas temperaturas: las temperaturas elevadas, guantes resistentes al calor son adecuados. Guantes vienen en diferentes formas, tamaños y materiales. Guantes resistentes al calor básicas se hacen a menudo de algodón, mientras más avanzadas guantes resistentes al calor están hechos de materiales como caucho de nitrilo, Kevlar. Al elegir guantes resistentes al calor, esté la temperatura que esté trabajando dentro de la operación entre los guantes de.</li>
		<li>Sostenidos: al manipular agujas, navajas de afeitar, cuchillas o cualquier otro tipo de elemento que podría cortar o punzar la piel, deben usarse guantes resistentes a la punción y corte. Los materiales comunes incluyen Kevlar y cuero. Corte y guantes resistentes a menudo cuentan con placas insertadas.</li>
		<li>Fuerzas mecánicas: guantes resistentes lpes los impactos se deben usar para protección contra fuerzas mecánicas. Guantes resistentes lpes los impactos se hacen con relleno agregado, como capas de espuma o gel de.</li>
		<li>Radiación: al manejar con o trabajar cerca de material radiactivo, guantes de atenuación de la radiación son apropiados. Plomo caucho guantes son eficaces en la protección de las manos de la radiación (mejor con el aumento de espesor), pero son pesadas y difíciles de trabajar con. Alternativas comunes para conducir incluyen titanio, bismuto y tungsteno. Mientras que no es tan eficaz en el blindaje de radiación, como plomo, los materiales alternativos no tienen que ser eliminados como residuos peligroso es de plomo.</li>
	</ol></li></ol> 3. Protección de cara <ol><li>protección de la cara está diseñado para proteger los ojos y pulmones de salpicaduras de químicos, vapores químicos, polvos aerotransportados, partículas voladoras, intensa radiación de la luz, calor y gases nocivos. Hay varios tipos de protección de desgaste de la cara que están disponibles para evitar daños a los ojos y los pulmones, incluyendo anteojos, gafas, caretas, respiradores y máscaras de gas. Elegir el correspondiente desgaste de cara debe hacer según los tipos de peligros asociados a la tarea. Gafas de seguridad son parte del mínimo que PPE requerido para introducir un espacio de laboratorio. Las gafas de seguridad que se requieren deben observar norma Z87.1 de ANSI. Deben tener protectores laterales, resistente al impacto, proporcionan protección contra partículas y proporcionar una protección básica contra las salpicaduras químicas.</li>

Hay muchos peligros en el laboratorio, pero la elección correcta del equipo de protección personal puede hacer que sea un lugar más seguro para trabajar. El equipo de protección personal, o EPP, ayuda a proteger a las personas de los peligros. Incluye ropa de laboratorio adecuada, así como artículos como guantes, gafas de seguridad, protectores faciales y batas de laboratorio. El EPP que use depende del peligro específico presente. Además, se necesita equipo especializado para situaciones como el frío extremo, el calor extremo y la radiactividad. En este vídeo, te mostraremos cómo vestirte para el laboratorio, así como algunos EPI especializados. Al ingresar a un laboratorio, use el EPP mínimo. Esto incluye una camisa de manga larga, pantalones largos y zapatos cerrados. Use una bata de laboratorio ignífuga, que le quede bien y esté abotonada, ya que las batas sueltas corren el riesgo de engancharse en los objetos. Si necesita más protección contra las salpicaduras o el calor, use un delantal de goma. Siempre use gafas de seguridad en el laboratorio. Estos deben tener protectores laterales, ser resistentes a los impactos y proporcionar protección contra partículas voladoras y salpicaduras de productos químicos. Los anteojos recetados no brindan estas protecciones, por lo tanto, también se deben usar anteojos protectores. Por último, para evitar que te enganches con un objeto, quítate las joyas colgantes, como los pendientes, y ata el pelo largo hacia atrás. Los guantes son una parte esencial del EPP, ya que las manos suelen ser la parte del cuerpo más cercana a los peligros. Hay muchos tipos de guantes resistentes a los productos químicos, como el látex, el nitrilo, el neopreno, el polietileno y el cloruro de polivinilo. El tipo de guante que use depende de las sustancias con las que trabaje. Para decidir qué guante usar, consulte una tabla de compatibilidad química. La tabla proporciona información sobre la resistencia del guante a diversos productos químicos. Además, enumera el tiempo de avance, que es el tiempo necesario para que un producto químico penetre en el guante. Diferentes peligros físicos requieren diferentes tipos de guantes. Los guantes criogénicos son más largos que los guantes normales y están hechos de una capa exterior de nailon y una capa interior de poliéster. Utilice estos guantes cuando manipule materiales extremadamente fríos como el nitrógeno líquido. Los guantes básicos resistentes al calor están hechos de algodón, mientras que los más avanzados están hechos de caucho de nitrilo o Kevlar. Cuando use estos guantes, asegúrese de que la temperatura esté dentro del rango de funcionamiento de los guantes. Los guantes resistentes a cortes y pinchazos pueden estar hechos de Kevlar o cuero, y pueden tener placas insertadas. Use estos guantes cuando manipule objetos como agujas. Cuando trabaje con fuerzas mecánicas altas, use guantes resistentes a los impactos. Estos tienen acolchado adicional, como capas de espuma o gel. Por último, la radiación requiere guantes especiales de atenuación. Los guantes de goma con plomo brindan la mayor protección, pero son difíciles de trabajar y deben desecharse en los desechos peligrosos. Los guantes forrados con otros metales como el tungsteno son más fáciles de trabajar, pero no brindan tanta protección. Las gafas de seguridad brindan suficiente protección para muchas tareas, pero a veces se necesita una protección facial más sustancial. Si está trabajando con sustancias que emiten partículas finas en el aire, use un respirador para proteger sus pulmones. Cuando trabaje con productos químicos peligrosos que puedan salpicar, materiales que provoquen chispas voladoras o calor, use gafas protectoras o un protector facial completo. Para la radiación ultravioleta, infrarroja o visible intensa, use anteojos con sombra o un protector facial con sombra. Además, debe usar protección para los oídos cuando se exponga a niveles de ruido superiores a 85 decibelios. Tanto los tapones como las orejeras reducirán el nivel de ruido entre 15 y 30 decibelios. Use ambos simultáneamente si el ruido supera los 105 decibelios. Por último, los EPI no siempre proporcionan suficiente protección contra peligros, y los controles de ingeniería, como las campanas extractoras, también reducen los riesgos. Acabas de ver la introducción de JoVE a los equipos de protección personal. Ahora debe comprender la ropa básica de laboratorio, los guantes y la protección facial. ¡Gracias por mirar!

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 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.

proper waste disposal

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...
