The exposure limit value of a gas refers to the maximum concentration of that gas in the air that a person can be exposed to without experiencing harmful effects. This value is typically expressed in parts per million (ppm) or milligrams per cubic meter (mg/m3) and varies depending on the specific gas in question. It is important to follow exposure limit values to ensure the safety and health of individuals working with or around gases.

The exposure limit value (ELV) of a gas is the maximum concentration of that gas that is allowed in the air of a workplace. ELVs are set to protect workers from the harmful effects of exposure to gases, such as respiratory problems, cancer, and other health issues.
ELVs are typically expressed in parts per million (ppm) or milligrams per cubic meter (mg/m³). The ELV for a particular gas will vary depending on the toxicity of the gas and the type of work being performed.
In the United States, ELVs are set by the Occupational Safety and Health Administration (OSHA). OSHA's ELVs are based on the recommendations of the National Institute for Occupational Safety and Health (NIOSH).
NIOSH publishes a document called the "Recommended Exposure Limits" (RELs) which contains ELVs for a wide range of gases and other chemicals. RELs are not enforceable by law, but they are often used by employers to set their own workplace ELVs.
It is important to note that ELVs are not always the same in different countries. For example, the ELV for benzene in the United States is 1 ppm, while the ELV for benzene in the United Kingdom is 5 ppm.
Employers are responsible for monitoring the levels of gases in their workplaces and ensuring that they do not exceed the ELVs. If the levels of gases in a workplace exceed the ELVs, employers must take steps to reduce the exposure of workers to those gases.
