2.6 The level of risk determines the type of agent that may be used to decontaminate as there are agents for different risks, low risk is water and detergent" medium risk is disinfectants and high risk is sterilizing agents. For example, cleaning a soup spillage on a surface would be low risk and only requires hot water and detergent like washing-up liquid (fairy,
By extending the life of fluids, the customer also saves time on draining and refilling fluid tanks, thus reducing downtime. Not only is it more convenient for customers to decrease downtime, but Kathon MWX is easy to use and requires no upkeep as it does the hard work of maintaining the customer's tank. Customers simply hook it and forget it for up to one month as it cleans. Unlike its competitors, Kathon MWX kills both bacteria and fungi, works with 70% of metalworking fluids, and eliminates odor, stains, and potential corrosion. 2) Why isn't MWX selling?
Therefore the alkalinity of water samples is being calculated. In the second approach, the two volume readings for the respective amounts of sulfuric acid used are being determined an indicator based method. Congo red and bromocresol green are being used as the indicators. Procedure (Outline provided as pre-lab): A. The pH meter was calibrated using standard pH solutions provided.
To keep the colors from fading, washing the fabric and drying it is good, but the key ingredient is soda ash. You sprinkle soda ash into a tub of water and let your fabric soak for a minute or two. The soda ash will lock in your dye and make your colors more vibrant and they will be less likely to fade. You can find soda ash in most craft stores. The amount of soda ash to use varies so it is a good idea to read the directions before adding it.
Post-Lab Questions: 1. Restate your hypothesis. Was it confirmed or denied? How do you know? If I put a mixture of potting soil and oil/vinegar/laundry detergent it will make four different types of dirty water.
How Are Water Quality Standards Determined? No name EVS 1001-51 June 25, 2012 Professor Thomas Rich How Are Water Quality Standards Determined? The earth is made up of mostly water even though we may not notice or see it, but water plays a very important part of life even though we may not think of it. Just our day to day activity everybody needs water at least seventy five percent of the day whether it’s to drink, cook, or wash its needed. Often times people use the water people never stop to think or wonder where are we receiving the water or the quality of the water that are used in the food we eat.
Identify the processes (e.g., coagulation) that were used in this lab and describe how they were performed. You start out with the contaminated water that has not been filtered out or has not had any chemicals added to it, this is many done so air can meet the water and this gives the chemicals and gases to release. I then added Alum to the dirty water since when mixing Alum with the dirty water it allows all the big particles to “stick” to the Alum and then pushes all of these particles to the bottom of the water. The dirty water is then put through a filter of sand, charcoal, and gravel in order for any of the smaller particles to stick to them and makes the water clean and free of any other particle. After I did all this I then had to add a few drops of bleach so I could disinfect the water from any other dirt
Water quality and contamination SCI 207: Dependence of man on the environment 7 April 2014 Water Quality and Contamination Introduction Body Paragraph #1 - Background: All of mankind relies on potable public or private drinking water supply to survive. “Testing of water quality on a regular basis is, therefore, an important part of maintaining a safe and reliable source” (Borah, Bhuyan, & Sarma, 2010). As stated by the World Health Organization (WHO), “Catastrophic events can result in periods of very degraded source water quality and greatly decreased efficiency in many processes, or even system failure, greatly increasing the likelihood of a disease outbreak (2011). Body Paragraph # 2 - Objective: The purpose of this study is to show the importance of having a uncontaminated water supply. People may contract serious illnesses or even worse, die from drinking contaminated water.
If a soldier can not provide at least four serviceable uniforms, then the soldier has the right to be given the chance to buy new uniforms or the uniforms will be provided for him and or her and money deducted out of the soldiers next pay period. In order to be successful at keeping your ACU’s clean you must wear your coveralls if you are indeed a mechanic working in a motor pool environment. The coveralls are kept clean is by washing them at least twice a week or at least once a week. Soaking them has been the best way to get oil, grease and other stains out of them. The best way to soak them is in a sink with cold water and OXY clean for a couple of day.
The waste management program consists of two programs such as the recycling and waste management. The waste prevention program is responsible for helping reduce waste before it is formed. Leaders are responsible for educating the staff on the importance of waste management and recycling and ways to maintain a clean environment and express the benefits for future generations to come. Once the staff comprehends the concept and accepts it, it will not be too difficult to get them to use utensils that are non-disposable. By using non disposable utensils, plates and cups, we are able to meet sanitary standards in the facilities.
