"228 ppm of natural gas is not unsafe as long as there is no way for it to increase in concentration. 5000ppm in a confined space is considered explosive. Since 5000ppm is considered the lower explosive limit of natural gas, it is reasonable to assume that enough oxygen has been displaced to possibly cause asphyxiation."
(improvement:)As a 33-year veteran HVAC contractor and Gas Fitter instructor, I believe that even 1 ppm of combustible gas is unsafe. The reason is that I have seen "safe" (low-level) gas leaks blossom to hazardous conditions within 1 hour. You cannot assume that 228 ppm of natural gas will remain at that level.
Also, the lower explosive limit of natural gas is 4%, which converts to 40,000 ppm.
What else can I help you with?
How much mercaptan is in natural gas?
The amount of mercaptan in natural gas can vary, but typically it is added at levels around 1-30 parts per million (ppm) to give natural gas its characteristic sulfur-like odor. This odorant is added for safety reasons to help detect potential gas leaks.
How many parts per million of CO2 is 2.5 mole?
To convert from moles to parts per million (ppm) for a gas like CO2, you need to know the volume of the gas at standard temperature and pressure (STP). At STP, 1 mole of ideal gas occupies 22.4 liters. From there, you can calculate the ppm using the formula: ppm = (moles of gas / total moles of gas) * 1,000,000.
Is 30 percent of the air around as carbon dioxide?
No, the amount of carbon dioxide in the atmosphere is 0.04% or 400 ppm (parts per million). This has risen since the Industrial Revolution from 280 ppm, when we began burning fossil fuels (coal, oil and natural gas).
What is the least abundant natural greenhouse gas?
The three natural GHGs in the atmosphere are:Carbon dioxide concentrations were 280 ppm in the late 1700s rising to 401 ppm today. The 1700 value is probe;y close to natural/Methane in the atmosphere was about 900 ppm in preindustrial times and is now 1,800 ppbNitrous oxide in the atmosphere rarely exceeded 280 ppb since prehistoric times.It is now 328 ppbThese data indicate that nitrous oxides are the lowest naturally occurring GHG.
Is nitrogen in the atmosphere about 380ppm?
No. Nitrogen is about 78% of the atmosphere or 780,000 ppm. 380 ppm is about the concentration of carbon dioxide

How to convert 10 ppm mole of H2O to ppm wt in natural gas?
To convert ppm mole of H2O to ppm wt in natural gas, you need to know the molecular weight of water (H2O), which is 18 g/mol. Once you have this information, you can use it to convert between the two units. This conversion involves considering the molecular weight of the components in the mixture.
1ppm of mercaptan equals how many pounds in 1mscf of natural gas?
1 ppm of mercaptan in 1 million standard cubic feet (mscf) of natural gas would be equivalent to 1 pound of mercaptan.
How you convert ammonia liquid pounds to gas ppm?
To convert from ammonia liquid pounds to gas ppm, you need to know the concentration of the gas in the air. This conversion requires additional information such as the volume of the space, temperature, and pressure to calculate the ppm concentration of the gas. It is not a direct conversion since ppm is a concentration measurement while pounds represent a mass measurement.

What is the full form of ppm in gas?
Parts per million (ppm) in gas refers to the measurement of concentration of a particular gas in the air. It represents the ratio of the volume of the gas to the total volume of the air, expressed in parts per million.
How can be measured PPM by volume?
PPM by volume is typically measured using a gas concentration analyzer or gas detector. The device measures the volume of a particular gas in a given volume of air and expresses it in parts per million (PPM). This measurement is commonly used in environmental monitoring, industrial hygiene, and indoor air quality assessments.
How much bleach and Windex will create 10 ppm of chlorine gas?
Mixing bleach and Windex can create toxic vapors and should never be done. It is unsafe and can result in harmful chemical reactions, including the production of chlorine gas, which is extremely dangerous and can cause severe respiratory problems and even death.
What are the recommended alarm levels for ammonia gas detection?
A warning alarm is usually set at 25 ppm. The main alarm is usually set at 50 ppm.
