That's about the same size as four-and-a-half parking spaces. The large surface area allows us to get all the oxygen we need when we breathe. On the other hand, that is a massive area for toxic gases to get into our bodies. Read on to learn more about how different gases harm our bodies. Certain industries, such as chemical manufacturing and petroleum processing, deal with toxic chemicals and the potential for exposure to harmful gases in evident.
However, we may also be exposed to dangerous gases in our own homes. It is best to inform ourselves about the possibles risks and how to minimize them. There may be countless kinds of chemicals that, when inhaled, can cause harm. Paracelsus, the father of toxicology , famously believed that any substance can be either harmless or deadly. It is emitted from coal, gas, and diesel engines. That includes gas and oil appliances.
Also, it is found in cigarette smoke and coal mines. We're almost all exposed to it in some way but this can often lead to tragedy. For this reason, it's known as the "silent killer". It can be dangerous in high concentrations, however. This can occur in poorly ventilated and crowded areas with low oxygen content.
It is very irritating for the skin, eyes, and mucous membranes. Total oil production figures include crude oil, natural gas liquids, and other liquid energy products. On top of oil, the United States produces significantly more natural gas than Saudi Arabia. The tobacco plant, as is well known, produces a virulent poison known as Nicotine.
For comparison, the gas may be passed through a test-tube containing an equal amount of distilled water. It is allowed to cool, and hydrogen sulphid gas is passed through it for about five minutes. They affirmed it was an antidote to all poison; that it expelled rheums, sour humours, and obstructions of all kinds. He lived in a perpetual fear and danger of discovery; and discovery now was but another name, for poison—prison—death.
New Word List Word List. If phosgene liquid comes into contact with food, people may be exposed by eating the contaminated food.
How phosgene works Poisoning caused by phosgene depends on the amount of phosgene to which a person is exposed, the route of exposure, and the length of time that a person is exposed. Phosgene gas and liquid are irritants that can damage the skin, eyes, nose, throat, and lungs. Immediate signs and symptoms of phosgene exposure During or immediately after exposure to dangerous concentrations of phosgene, the following signs and symptoms may develop: Coughing Burning sensation in the throat and eyes Watery eyes Blurred vision Difficulty breathing or shortness of breath Nausea and vomiting Skin contact can result in lesions similar to those from frostbite or burns Following exposure to high concentrations of phosgene, a person may develop fluid in the lungs pulmonary edema within 2 to 6 hours.
Exposure to phosgene may cause delayed effects that may not be apparent for up to 48 hours after exposure, even if the person feels better or appears well following removal from exposure. Therefore, people who have been exposed to phosgene should be monitored for 48 hours afterward. Delayed effects that can appear for up to 48 hours include the following: Difficulty breathing Coughing up white to pink-tinged fluid a sign of pulmonary edema Low blood pressure Heart failure Showing these signs or symptoms does not necessarily mean that a person has been exposed to phosgene.
What the long-term health effects are Most people who recover after an exposure to phosgene make a complete recovery. However, chronic bronchitis and emphysema have been reported as a result of phosgene exposure. How people can protect themselves and what they should do if they are exposed to phosgene Leave the area where the phosgene was released and get to fresh air.
Quickly moving to an area where fresh air is available is highly effective in reducing the possibility of death from exposure to phosgene. If the phosgene release was outdoors, move away from the area where the phosgene was released. Go to the highest ground possible, because phosgene is heavier than air and will sink to low-lying areas. If the phosgene release was indoors, get out of the building. If you think you may have been exposed, remove your clothing, rapidly wash your entire body with soap and water, and get medical care as quickly as possible.
Removing and disposing of clothing: Quickly take off clothing that has liquid phosgene on it. Any clothing that has to be pulled over the head should be cut off the body instead of pulled over the head. If possible, seal the clothing in a plastic bag.
Then seal the first plastic bag in a second plastic bag. Removing and sealing the clothing in this way will help protect you and other people from any chemicals that might be on your clothes.
If you placed your clothes in plastic bags, inform either the local or state health department or emergency personnel upon their arrival. Do not handle the plastic bags.
