Methane is not toxic below the lower explosive limit of 5% (50000 ppm). However, when methane is present at high concentrations, it acts as an asphyxiant. Asphyxiants displace oxygen in the air and can cause symptoms of oxygen deprivation (asphyxiation). The available oxygen should be a minimum of 18% or harmful effects will result. Methane displaces oxygen to 18% in air when present at 14% (140000 ppm). It is not expected to cause unconsciousness (narcosis) due to central nervous system depression until it reaches much higher concentrations (30% or 300000 ppm) - well above the lower explosive limit and asphyxiating concentrations. Effects of oxygen deficiency are: 12-16% - breathing and pulse rate are increased, with slight muscular incoordination; 10-14% - emotional upsets, abnormal fatigue from exertion, disturbed respiration; 6-10% - nausea and vomiting, inability to move freely, collapse, possible lack of consciousness; below 6% - convulsive movements, gasping, possible respiratory collapse and death. Since exercise increases the body's need for oxygen, symptoms will occur more quickly during exertion in an oxygen-deficient environment. Survivors of oxygen deprivation may show damage to some or all organs including the central nervous system and the brain. These effects may or may not be reversible with time, depending on the degree and duration of the low oxygen and the amount of tissue injury. Some closely related aliphatic hydrocarbons (propane, butane and isobutane) may be weak cardiac sensitizers in humans following inhalation exposures to high concentrations (greater than 5% for isobutane and greater than 10% for propane). Cardiac sensitizers may cause the sudden onset of an irregular heartbeat (arrhythmia) and, in some cases, sudden death. Sudden deaths have been reported in cases of substance abuse involving butane and propane. Under stressful conditions and with exposure to high concentrations, the effects of cardiac sensitization may be important for some hydrocarbon gases. The asphyxiant effects of methane may enhance cardiac sensitization. SOURCE: http://www.ccohs.ca/oshanswers/chemicals/chem_profiles/methane/health_met.html
What else can I help you with?
What are the products from combustion of 2-methyl- and 3-ethyloctane?
Carbon dioxide and water
What is the purpose of secondary air in the incinerator?
The purpose of secondary air in an incinerator is to enhance combustion efficiency by providing additional oxygen to the combustion chamber. This helps to ensure that any unburned or partially burned gases are fully oxidized, reducing emissions of harmful pollutants and improving overall combustion stability. By promoting complete combustion, secondary air also contributes to the effective breakdown of waste materials and minimizes the generation of residual ash.
What is the product of oxygen and a fuel?
No, oxygen is an oxidizer. Combustion reactions are oxidation-reduction reactions. The reaction could not happen without the oxidizer, but oxygen cannot be considered the fuel. The fuel is the compound which is being oxidized: i.e. Carbon oxidized to carbon dioxide.
Is this chemical equation considered a combustion reaction and if yes why 4Na plus O2 equals 2NaO2?
4Na+O2=2Na2O? That must be the equation... Im not sure what you're asking... But, in a combustion reaction, something reacts with oxygen gas (O2). In this equation sodium is reacting with oxygen... So, yes, this is a combustion reaction.
What is the reason for having a combustion chamber on a rocket?
A combustion chamber is where combustion occurs in a controlled fashion. Because the basic idea of a rocket is burning fuels and directing them in the opposite direction to that of travel, a controlled burning - as happens in the combustion chamber - is exactly what a rocket needs to work.
Are electronic cigarettes safe?
No one really knows yet. Electronic cigarettes are a new product, so there has not been time to study and evaluate their effects on the human body. However, it is probably safe to say that they are substantially less harmful than traditional cigarettes. The by-products of combustion are what makes cigarettes so harmful. There is no combustion with an electronic cigarette, hence, there are no harmful combustion by-products.

When incomplete combustion occurs what additional by-products of combustion are created?
When incomplete combustion occurs, it produces by-products such as carbon monoxide (CO), soot (carbon particles), and volatile organic compounds (VOCs). Unlike complete combustion, which primarily generates carbon dioxide and water, incomplete combustion results in harmful emissions that can pose health risks and contribute to air pollution. The lack of sufficient oxygen during the combustion process leads to these additional harmful substances.
What is the name of the products when a hydrocarbon is burned off and there is incomplete combustion?
When a hydrocarbon undergoes incomplete combustion, the primary products formed are carbon monoxide (CO) and soot (carbon particles), along with water (H₂O). Unlike complete combustion, which produces carbon dioxide (CO₂) as the main byproduct, incomplete combustion results in the release of harmful pollutants such as carbon monoxide, which is toxic. This type of combustion typically occurs when there is insufficient oxygen available for the reaction.
The waste products of combustion leave the internal combustion engine through the?
The waste products of combustion leave the internal combustion engine through the exhaust valve.
What are the products of combustion of a hydrocarbon?
The complete combustion of a hydrocarbon would give carbon dioxide and water as the only products.
What are the products of combustion of a marshmallow?
If the combustion is complete, carbon dioxide and water.
What are the primary products of complete combustion of fossil fuels.?
Carbon Dioxide and water are the primary combustion products of fossil fuels.
What are the primary products of complete combustion of fossil fuel?
Carbon Dioxide and water are the primary combustion products of fossil fuels.
What is the downside of the products formed by complete combustion reactions on which we rely for energy and transportation?
The products of combustion are water and carbon dioxide.
What are problems with combustion?
Some of the problems with combustion include air pollution from the release of harmful gases and particulates, contribution to global warming through the release of greenhouse gases like carbon dioxide, and depletion of natural resources. Combustion also leads to the generation of ash and other waste products that need to be properly managed.
What products are formed from incomplete combustion during the process?
If refering to hydrocarbons, complete combustion is carbon dioxide and water. Incomplete combustion may include any other compounds, e.g. carbon, carbon monoxide, aldehydes, acids, peroxides...
