PROCEDURES AND PRACTICES WHY THEY ARE CARRIED OUT
Ordering procedures. Ordering procedures are important because they ensure that the scientists do not run out of equipment for the experiment. In addition to this, such procedures save time as the scientists do not need to figure out the equipment they need while conducting any experiments. This procedure is carried out usually by the senior member who will list the equipment he/she does and does not have. They would then purchase the equipment they have run out of online.
Maintaining equipment. The need for maintaining equipment is crucial for the running of the lab. Regular maintaining equipment increases the accuracy of results because equipment is being looked after. If equipment is not maintained, then there could be a greater chance of errors occurring during experiments. Moreover, maintaining equipment saves money because the company is ensuring that the equipment does not break which emphasises how this is a cost-effective method.
Carrying out tests Carrying out tests is important because the experimenter is looking to get results. If the results being looked for are not obtained, then there is something wrong with the experiment. This procedure is carried out by the team who would list out their aim and methods. They would then show this to a lab supervisor to ensure they are not missing out any This procedure is carried out by the team who would list out their aim and methods. They would then show this to a lab supervisor to ensure they are not missing out any important information.
Desiccators and vacuum storage Desiccators are important because they dry chemicals before they are used to prevent any chemicals escaping.
Store Management Store management is important because not labelling and storing materials in the right groups could lead to harmful substances reacting with each other, which could harm individuals and the building itself. Therefore, it Is important that flammable and explosive substances should be put in separate components. This would not cause harm at all and would save the company a great deal of money. Stock rotation is important because it guarantees that both old and new equipment are being used.
Collection/ transport of substances and equipment for disposal Substances are collected and recycled so that they can be used again.
Calibration of equipment Calibration of equipment is an important procedure and practice because it verifies that accurate and reliable results can be obtained. The information the equipment gives must always be accurate because it can be used to determine certain things later on for example, certain chemicals. An example of an equipment that is calibrated are PH metres as they can determine the nature of PH solutions. If PH metres were not calibrated, then they may not be able to give readings that can be reproduced by others which decreases the accuracy of results. This procedure is carried out by the team who would list out their aim and methods. They would then show this to a lab supervisor to ensure they are not missing out any important information.
Handling of materials. It is very important that materials are handled with precaution because if they are not it can lead to materials being damaged or breaking. This is a disadvantage because majority of laboratory equipment are expensive, and purchase of the same equipment could be difficult for the company as it could exceed their budget.
Handling of materials involves carefully and properly storing, identifying and disposing materials.
Handling and use of glassware. When handling glassware it is important to use both hands when moving it because it could break which would mean that this could affect the results of the experiment/ waste money on buying more glass. Glassware has important uses in the scientific industry because they play a big factor on how experiments can run smoothly. Glassware in the scientific workplace is very fragile. This means that when handling glass a scientist would use both hands to avoid breaking equipment. Hot or cold glass should be handled with insulated gloves to avoid accidents. Glassware are used in many ways for example, beakers are used for mixing and transporting fluids and Pipets are used for drawing precise measurements of fluids.
Instrumentation techniques It is important to know how to use equipment otherwise, the equipment could be damaged. If this were to happen then the company would have to repair the equipment which is not free.
Handling of solvents and poisons. If poisons are not covered then it could harm an individual. Also, if solvents are stored in a safe place then there will be no accidents. However, if this process is not followed then danger could occur for example liquids spilling.
Transfer of materials. This is an important procedure and practice because it ensures that specific materials are handled carefully when they are moved around. It is also carried out because it ensures that the supplier distributes the materials safely to the lab.
Handling and disposal of radioactive substances It is important to handle radioactive substances by storing them in a place far away from other materials such as flammable materials. Otherwise, chemicals could react together which would cause harm to individuals and the lab itself. If this process is not carried out it can result in bins overflowing which can cause hazards in the scientific workplace.
Use of ovens Ovens are used in a scientific workplace because of their drying properties, annealing (heating and cooling materials such as glass to reduce the hardness.
Operation of the fume cupboard The operation of the fume cupboard is very important because without it there could be accidents as hazardous fumes would pervade everywhere and harm everyone.
Use of centrifuges. Centrifuges are very important in the scientific workplace because of their important properties such as their ability to separate molecules of different densities.
