Chemical Care
Dangerous chemicals can be found in every corner of your house. If they are not stored or used carefully it can cause minor to life threatening injuries. However, if you use them properly there are considerably safe.
What to do if an accident happens?
Call 999 or the fire department, tell them what happened and the location immediately. Stay on the phone until they tell you to hang up.
Stay away from the scene decrease the time you are exposed to the chemicals and reduces breathing in the chemicals.Some of the chemicals will set fire to or explode.
Avoiding touching the chemicals and stay away from the chemicals.
Avoid inhaling gases, fumes or smoke. If you can, cover your mouth with cloth.
Stay away from the victims the substance might be infectious.Move the victims to fresh air if the medicals say it is safe to have contact with the victims. Put things that the victim has had contact with in a plastic bag.
Put cold water on the skin or the eyes for at least 15 minutes make sure it is running water. Remove contact lenses and if water is not near you brush off the chemical make sure the victim's eye is closed.Brush the chemical away from the victim or you.

Antifreeze
Ethylene glycol is extremely poisonous. If you inhale in the fumes it can cause dizziness; if you or your child swallow antifreeze it can give severe damage to the heart, kidneys and brain.It can be fatal if antifreeze is swallowed.
Safety tips:
Always wear gloves when you clean up antifreeze because ethylene glycol can be absorbed through your skin.
Also, keep your pets away from spilled antifreeze. Your pets are attracted to antifreeze because of its sweet smell, if they lick or drink the substance it can kill them, Ke...

Examples of substances classified as highly flammable include sodium, magnesium powder, methanol, petrol and the contents of many aerosol canisters.
Oxidising
Provides oxygen to make other substances burn more fiercely.
SYMBOL LETTER - O
These types of substances can give vigorous reactions which may cause a fire or damage the living tissue resulting in chemical burns.
A vast amount of care should be given when handling or storing oxidising chemicals because they can react with combustible materials( materials that can be burnt) increasing to make an explosive atmosphere. Some substances have flammable properties even if it isn't in contact with combustible material.
Examples of substances classified as oxidising include hydrogen peroxide, chromate and persulphate salts and chemicals used to disinfect swimming pools.
The purpose of this experiment was to examine how the stoichiometry, “the quantitative relationships between substances involved in a chemical reaction”, can be applied to determine the quantity of sodium hypochlorite found in a bleach product. This experiment allowed it to determine how much oxidizing agent is in a cleaner by using a redox reaction, which is a reaction involving the transfer of electrons from the compound being oxidized to the compound being reduced. To determine the amount of oxidizing agent, it is necessary to accurately measure out known amounts of redox reactants, know the stoichiometry
For the first phenomena, he noted how all combustions involved the formation of fire or light. With that in mind, Lavoisier also observed that this combustion occurs only through dephlogisticated air / pure air. Other airs (e.g. carbon dioxide) act as a fire extinguisher similar to that of water. Another combustion phenomenon he outlined was how the weight of the burnt material directly relates to the amount of air used in the reaction. Moreover, he also described how certain substances turn into acids after it has been burn...
It can kill you! Yeah, this thing is silent and deadly! Colorless and odorless, you never know where it can be leaking from. Can you smell? Nope! Can you taste it? Nahhh! Have you figure it out yet? The thing that might take your life right now, or maybe tonight or maybe tomorrow. No? Well, I’ll be nice and tell you. The poisonous demand that lurk through the air so free and careless is Carbon Monoxide or CO. In this paper, you will learn all what and how it can kill you plus how you can protect yourself from Mr.CO

However this information was written in the 1960s and a lot has changed since then. Not everything she says is true in the world today. I am going to explain what is still happening in our world and how we are trying to make our world better. With all of these great changes in our world we have made some outstanding advances. My first point I’m arguing against is the fact that she said most people don 't know what these chemicals are or what they do. For an example the MSDS (Material Data Safety Sheet) is required by law to be in every healthcare facility and everyone working in these facilities are trained to know where they are located and how to use them. “It’s a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It also contains information on the use, storage, handling and emergency procedures all related to the hazards of the material” ("OSH Answers Fact Sheets.”). Also she said that there’s 500 chemicals being made in a year that has changed immensely. “More than 7 million recognized chemicals are in existence, and approximately 80,000 of them are in common use worldwide” ("Chemical Industry Archives.").However just because we are making more chemicals it does not mean we use all of them. In fact we are
Anhydrous ammonia is stored as a liquid in pressurized tanks and after it has been sold to local farmers, they use it by injecting it directly into their soil where it then turns into a gas. It has a melting point of around -108 degrees Fahrenheit and an explosive range between a Lower explosive limit (LEL) of 15% and an Upper explosive limit (UEL) of 28% when mixed in air. Ammonium nitrate is typical found and used in its prill form where it is spread across the fields as a fertilizer. Ammonium Nitrate does not typical, under normal circumstances, pose an explosive hazard alone by itself but when combined with some sort of fuel it will act as an oxidizer during that process, literally adding fuel to the fire. “Both of these common fertilizers can become explosive under the right conditions.” (Fernandez & Schwartz, 2013)
dangerous for the body, and can many times lead to being very ill or death.
Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death.
Wear gloves and proper cloths if handling the infected animals to prevent the direct contact.
...and MEA. These chemicals are said to be linked with breast cancer, skin rashes, estrogenic, hormone disruptor, linked to liver and kidney cancer, and irritates the eye.
(2014) shed light on two key components for infection control, which includes protecting patients from acquiring infections and protecting health care workers from becoming infected (Curchoe et al., 2014). The techniques that are used to protect patients also provide protection for nurses and other health care workers alike. In order to prevent the spread of infections, it is important for health care workers to be meticulous and attentive when providing care to already vulnerable patients (Curchoe et al., 2014). If a health care worker is aware they may contaminate the surroundings of a patient, they must properly clean, disinfect, and sterilize any contaminated objects in order to reduce or eliminate microorganisms (Curchoe et al., 2014). It is also ideal to change gloves after contact with contaminated secretions and before leaving a patient’s room (Curchoe, 2014). Research suggests that due to standard precaution, gloves must be worn as a single-use item for each invasive procedure, contact with sterile sites, and non-intact skin or mucous membranes (Curchoe et al., 2014). Hence, it is critical that health care workers change gloves during any activity that has been assessed as carrying a risk of exposure to body substances, secretions, excretions, and blood (Curchoe et al.,
Hazardous materials are in almost every community placing everyone at some level of contact with various chemicals almost daily as they exist throughout the community and in our households. Chemicals are used for a variety of purposes such as in the water purification process, by farmers to produce a higher crop yield and are used in households and almost every business. Not all chemicals are hazardous but most pose some level of risk to people...
According many scientific researchers, our entire population has been dowsed with chemicals. There are several aspects of this dowsing that should concern us. First, and foremost, many of these chemicals are suspected to have damaging health effects on humans, as well as, other life forms. Second, most of these chemicals have only recently been produced so the environment is clearly changing and being challenged by these newcomers. Third, almost all of these chemicals exist in the forms and amounts that they do because of human practices-including agricultural, industrial, and many domestic activities as well. Fourth, many of the chemicals that we produce don't get used in a productive way-that is, they are wasted, disposed of, and/or left abandoned; consider that less than 5 percent of pesticides actually make contact with their host target. Fifth, most, if not all, of the chemicals used have replacements that are much less harmful or toxic. And sixth, and perhaps most discouragingly, many of us knowingly buy and use these chemicals without a moment's hesitation.
The biosafety program ensures the competency of the laboratory staff in safely performing their job through training and documentation of technical expertise. The laboratory staff must manifest professional responsibility for management of research materials complying with appropriate materials management procedures. A hallmark of biosafety practices requires laboratory access to be limited to essential personnel only when work with biological agents is in progress. Biosecurity practices on the other hand ensure that access to the laboratory facility and biological materials are limited and controlled. An inventory system must also be in place so as to control and track biological stocks or other potentially hazardous biological agents in both biosafety and biosecurity programs. For biosafety, the transfer and shipping of infectious biological materials must comply with safe packaging, containment and appropriate transport procedures, while biosecurity ensures that transfers are controlled, tracked and documented relative to the potential risks of the materials being transferred. Both programs must involve the laboratory staff in the development of practices and procedures that fulfills the requirements of biosafety and biosecurity initiatives without hindering research or clinical/diagnostic activities. The success of both of these programs is anchored on a laboratory culture
To begin with, the first type of hazard/exposure is fire and explosion. Fire is highly flammable and the vapor is heavier than normal air. It can travel for a considerable distance to source of ignition and flash back. Fire can be of 3 types: small, large and fire involving tanks or cars or trailer loads. An acute hazard can be the vapor/air mixtures that cause explosions. One way of preventing is to not open flames and sparks as well as no smoking. It is also preferable to take off reactions in clo...
