Developing a Safe Scientific Workplace

Developing a Safe Scientific Workplace In a scientific workplace there are many various aspects that enable workers to do their job safely knowing they are protected from various precautions and laws. These aspects can be split up into the following sections: hazard symbols and hazcards, risk assessments, protective clothing and equipment, COSHH, CLEAPSS and HSE, general laboratory practises and quality standards. Hazards symbols and hazcards Harmful This is a substance that will most likely cause harm to the body if it comes in contact with the skin or ingested. An example of a harmful substance is chloroform, for the safety in a work place this substance would be stored in a tightly close and sealed container in a well-ventilated room as it can give off harmful fumes. Explosive This is a substance that combusts with a lot of energy when exposed to heat or a flame. An example of a substance that is explosive is ammonium nitrate, explosive substances must be stored in a durable box with a tight lid away from any heat source, as well as this is must be stored low down in case it is an impact explosive. Oxidising Oxidising is a substance that do not burn by themselves but they provide oxygen for flammable substances to burn. An example of a substance like this is potassium nitrate, for oxidising substances like this they must be placed in a tub/bottle with a lid on and store away from any flammable materials for the safety of people working with this product. Flammable A flammable product is when a substance is subjected to a high heat it produces a flame. An example of a flammable substance is gasoline/petrol which is highly flammable in liquid and vapour form. To store this and many other flammable substances it must be placed in preferably a durable metal container with a tight lid on so no substance or fumes will be let out, it also must be kept away from high heat or any source of flame. Corrosive A corrosive substance has the ability to deteriorate and burn away a surface, this is usually the skin in a science workplace. An example of a corrosive substance is hydrofluoric acid, this is a liquid as are most corrosive substances so they are stored in similar ways, they must be stored in unreactive plastic containers that have a tight lid on to avoid spillages. Irritant An irritant substance closely relates to harmful but doesn’t cause as much harm, an irritant causes irritation to the surface of the skin therefor can cause red marks. An example of this is acetone, this must be stored in a tough bottle with a safety lid that is usually stored on a shelf or in a cupboard. Toxic Toxic is labelled to substances that if exposed to it can cause death if enough is in contact with the body. An example of this would be ricin which is extracted from a bean off a plant, it is usually in powder form. For this particular substance and many other toxic substances it must be stored in a container with a secure lid and store in a locked cupboard, safe or room. Biohazard A biohazard is used in the labelling of biological materials that carry a significant health risk to humans. An example of this would be carmine which is a natural red pigment. To store biohazards they must be stored in a bottle or tub with a safety lid on which is locked away from humans and non-workers. Radioactive A radioactive substance emits energy as electromagnetic waves or moving subatomic particles causing ionization. An example of a radioactive material is uranium, all radioactive material must be stored within a radioactive proof area like in lead which stops radioactive particles from passing through, keep in a safe which also stops radiation. Environmental hazards Environmental hazards can cause harm to the environment meaning both plants and animals. An example of this would be mercury, mercury is a highly toxic metallic liquid. To store this place in a plastic bottle with a secure cap on top, as well as this keep it away from any drainage source as well as animals, plants or the outside. Risk assessments There are 3 categories under risk assessments, these are chemical hazards, physical hazards and biological hazards. Risk assessments are usually taken before an experiment, practical or before a job is undertaken. The following example risk assessment of the 3 categories is from when I completed the preparation of aspirin. Chemical hazards Chemical hazards are chemicals that can cause harm to the body if exposed to the skin or ingested. An example of a chemical hazard would be a corrosive burn from concentrated sulphuric acid, this would be a high risk and as a precaution you should wear gloves and carefully use, make sure to use in fume cupboard to avoid spillages on work surfaces, wear lab jackets too to protect core body, wear safety glasses to protect eyes. This would be the same for another chemical hazard which is irritation for ethanoic anhydride which unlike sulphuric acid is a low risk. In the case of the substance being in contact with the skin wash off quickly and put the area affected in ice or cold water. Physical hazards Physical hazards are something that can cause harm to the body excluding chemicals or biological substances. For example slipping on water spillages, this can be seen as a moderate hazard if equipment isnt set up correctly or if carelessness occurs. To avoid this make sure apparatus is in the middle of a flat bench and make sure if it uses water to connect it properly so avoid leaks, in the case of a spillage simply mop up using paper towels, if the slipping occurs then if injured get a first aid officer to check you. As well as this another example could be cuts from glass breakage which is once again a moderate risk if not properly cleared up, to avoid this make sure to handle equipment carefully, do not grip too hard or too little to avoid shattering, place in the middle of benches to avoid knocking off, keep a brush and glass bucket in case of breakage. In the case of cuts happening wash the wound and cover in a plaster, if deep then go to hospital to get stiches. Biological hazards A biological hazard is a substance that causes a threat to the health of a person, in the practical I did there was only one biological hazard which was the product aspirin itself, it caused a low risk but a moderate risk if ingested as we made it ourselves. To avoid this make sure to wear disposable gloves in case the product gets on your hands, if products gets on skin wash off and to no put product in the mouth. In case any of it is ingested you must go hospital as it wasn’t commercially made. Protective clothing and equipment Protective clothing equipment more commonly known as personal protective equipment is pieces of clothing or equipment that will protect the user against health or safety risks at work. It can include items such as safety gloves, eye protection such as goggles, visors and glasses, safety footwear and lab coat. Lab coat A lab coat is made out of cotton which absorbs the chemicals spilt onto the coat, because of this it is used to protect the core body and arm and stops yourself from being damaged in many different laboratory situations. Protective gloves Protective gloves are worn when there is a chance if a substance can harm your hands, the gloves are made out of neoprene or latex that are resistant to chemicals and are used to protect your hands when using something potentially harmful. Goggles These are used to give extra protection to the eyes, it covers all of your eyes including top bottom and sides, they have a PVC frame with polycarbonate lenses giving it strength whilst protecting eyes at it is unreactive. Visor These are used to cover whole of the face when using something potentially reactive/explosive, like the goggles they have a PVC frame with a polycarbonate visor giving it strength and protecting the whole face from chemical splashed due to the unreactive nature. Safety glasses Used to cover the front of the eyes and are used in all experiments as a safety precaution, like the previous two protective equipment, they have a PVC frame and polycarbonate lense giving strength and an unreactive ability. Safety boots Used to protect your feet when working around heavy objects that can potentially fall, safety boots are made out of leather and have steel toe caps, leather as a high resistance to chemicals, heat and flames and steel has a high breaking strength protecting the toes. COSHH, CLEAPSS and HSE COSHH, CLEAPSS and HSE are all laws that enable working in a scientific workplace to be carried out safely. COSHH COSHH is a law that requires employers to control substances that are hazardous to health. Most businesses use substances, or products that are mixtures of substances. Some processes create substance which could cause harm to employees, contractors and other people so must be disposed of properly. CLEAPSS CLEAPSS is an advisory service providing support in science and technology for a consortium of local authorities and their schools. The law includes: Independent schools, post-16 colleges, teacher training establishments and curriculum developers. CLEAPSS stands for Consortium of Local Education Authorities for the Provision of Science Equipment. HSE The Health and Safety Executive (HSE) is the national independent watchdog for work-related health, safety and illness. It acts in the public interest to reduce work-related death and serious injury across Great Britain’s workplaces. The Act makes sure to secure the health, safety and welfare of persons at work, for protecting others against risks to health or safety in connection with the activities of persons at work. General laboratory practises General Laboratory Practice includes a set of codes that provides an outline within a laboratory in which studies are planned, performed, monitored, recorded, reported and archived. These studies are undertaken to help assure regulatory authorities that the data submitted is a true reflection of the results obtained during the experiment/practical that has been completed and can therefore be relied upon when making assessments. This is part of a quality assurance procedure which is aimed at ensuring that products are consistently manufactured to a quality appropriate to their intended use. They provide guidelines for quality control and assurance in testing laboratories. Quality standards Quality standards look into all ranges of care, these can include examples like public health, healthcare, social care. Evidence relating to effectiveness and cost effectiveness, peoples experience of using services, safety issues, equality and cost impact are also considered. Although some standards are area-specific, there will often be substantial overlap across areas and this is considered during building of the standard. Where appropriate referrals are combined and developed as a combined quality standard. Many of the quality standards are started by the international standards organisation. Other commonly known organisations originating from the international standards organisation include: British Standards which is mostly used in the UK and Europe.

Pride and Poverty Essay

â€Å"It is a beggars pride that he is not a thief† (Japanese Proverb). In today’s economy people are shameless and would rather be on welfare and disability than get a job and earn a living. Pride has been discarded, and poverty has become normal. People in today’s society would rather lie and steal then make an honest living that they are proud of. However in Frank McCourt’s memoir Angela’s Ashes pride and poverty go hand in hand. During the time this memoir was taking place many families were very poor and didn’t have many possessions. One thing they could always hold dear was their pride. â€Å"The master says it is a glorious thing to die for the faith and Dad says it is a glorious thing to die for Ireland† (McCourt 113). This is important because from a young age children were taught to be proud of who they were and what they believed in. They were also raised in an era where it was almost assumed that every adult person either was an alcoholic or smoked cigarettes. It was â€Å"the norm†. Not because of an addiction but as a status quo or for relaxation during hard times. â€Å"A puff of the fag is the only comfort we have in the world† (McCourt 64). As Mam’s friend, Nora, says this Mr. Quinlivan he gets angry because he understands that all of the women at the St. Vincent De Paul have families at home starving but they can still find money to buy cigarettes. Pride is truly a huge part of the memoir. Frank clearly shows this in his writing: â€Å"Even the poorest of the poor don’t go out on Christmas Day picking coal off the road. There’s no use asking Dad to go because he will never stoop that low and even if he did he won’t carry things through the streets† (McCourt 99). This shows that even as a young child Frankie understands that even though his family isn’t â€Å"the poorest of the poor† his parent’s lifestyle force him and his brothers to humilify themselves and humbly do things to survive. Frankie gets frustrated at his parents when he gets older and starts to realize they can spend so much money on cigarettes and alcohol but they never have enough food in the house. â€Å" There may be a lack of tea or bread in the house but Mam and Dad always manage to get the fags† (McCourt 138). Even though the McCourt family doesn’t have any money Mam sends Malachy to the store to get cigarettes on their family’s tab. Throughout the book Mam and Dad spend a lot of money on cigarettes and alcohol and it isn’t necessarily for an addiction but for a getaway of sorts.

Becoming a Philosphy Scholar Too! - 1457 Words

Dear Student, Although Philosophy 3000 may be a required course at Fordham University, that does not mean it will not quickly become one of your favorite courses. If you are lucky enough to have Professor Sajber as your professor, I can guarantee that the various philosophers theories about morals and ethics that you will study will seem to come to life through open class discussions on hypothetical scenarios and examples to help you better understand the content, while relating it to realistic situations. Learning about the different philosophers theories on moral judgment allows you to question your own morals while looking at morality through a different lens. The philosophies on morality that truly made me rethink my moral judgment through presenting me with a different ethical perspective were the philosophers David Hume, Jeremy Bentham, and Immanuel Kant. The reading that resonated with me the most was David Hume’s, A Treatise of Human Nature. Before I began reading the text, I had a preconceived notion that Hume’s theory on moral decision-making was probably outdated and would not be able to be applied to today’s moral and ethical beliefs in society. However, my initial instinct was wrong and as soon as I delved deep into reading Hume’s theory, I quickly realized that his sentimentalist approach was a fresh perspective from other philosophers, such as Kant, who solely focus on morality through reason and the act of duty. Instead, Hume argues that reason is inShow MoreRelatedSocrates and Properties Essay3228 Words   |  13 Pagesmoment when the future of that interest might be in some doubt. But by offering consistently challenging and novel interpretations, and by arguing clearly and vigorously for their positions with reference both to the texts and to the work of other scholars, the authors guarantee a continuing debate on the topics. It is certainly one of the best introductions there is to Socratic thought, together with Vlastos Socrates, Ironist and Moral Philosopher and posthumous companion volume Socratic Studies

Mental Illness And Substance Abuse - 1133 Words

Abstract Families who are dealing with members who have mental illness and substance abuse face many problems. Particularly schizophrenia is characterized by delusional thoughts, seeing and hearing things that others don’t see or hear, loss of emotional expression and problems with cognitive skills and motivation (Elements, 2014). In some cases schizophrenia can cause the onset of substance abuse, in other cases substance abuse can mimic symptoms of schizophrenia. Medications such as antipsychotics can assist individuals with the symptoms of schizophrenia as long as they are properly diagnosed. Yet antipsychotics are proven to have significant side effects, some even life threatening (Muench Hamer 2010). A cycle can then begin to occur with individuals who are using substances to self-medicate. The purpose of this paper is to determine and explain the cycle that can occur with individuals diagnosed with schizophrenia who self-medicate with substances as well as the cycle of a ntipsychotics. Treatment will be discussed in the scope of treating the whole family. Keywords: mental illness, schizophrenia, antipsychotics, typical, atypical, substance abuse, cycle, self-medicate, treatment INTRODUCTION Schizophrenia is an illness that is chronic, severe and debilitating (NIMH, 2015).
