CARBON DIOXIDE. CAS number: 124-38-9. Molecular formula: CO 2. TLV–TWA, 5000 ppm (9000 mg/m 3) TLV–STEL, 30,000 ppm (54,000 mg/m 3) To view TLV and Documentation, you must be logged in as an ACGIH member or have previously purchased the documentation.

The revised IDLH for carbon dioxide is 40,000 ppm based on acute inhalation toxicity data in humans

Carbon Dioxide CO 2 Exposure Limit Sources & Research. ACGIH recommends an 8- hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for a 10-minute period. A value of 40,000 is considered immediately dangerous to life and health (IDLH value).

What are the health effects of carbon dioxide? CO2 is considered to be minimally toxic by inhalation. The primary health effects caused by CO2 are the result of its behavior as a simple asphyxiant. A simple asphyxiant is a gas which reduces or displaces the …

2011年9月28日 · OSHA’s former limit for carbon dioxide was 5000 ppm as an 8-hour TWA. The ACGIH has a 5000-ppm TLV-TWA with a 30,000-ppm TLV-STEL, and these were the limits proposed. NIOSH has a TWA REL of 10,000 ppm with a 10-minute 30,000-ppm ceiling limit; however, NIOSH (Ex. 8-47, Table N1) concurred that the proposed limits were appropriate.

an 8-hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for 10 minutes. A value of 40,000 is considered immediately dangerous to life and health (IDLH value). • Ventilation: All CO2 activities should be performed in a well-ventilated area. A minimum of 6 air exchange rate is ...

A measured flow of 99% carbon dioxide was introduced near the entrance of the test atmosphere, where it was mixed into a measured flow of dilution air from the flow-temperature-humidity control system. The carbon dioxide and dilution air flowed into a mixing chamber, and then into a …

What are fire hazards and extinguishing media for carbon dioxide? What are the stability and reactivity hazards of carbon dioxide?

As TLV and IDLH values may change, the current guidelines from the following sources should be consulted for up-to-date accuracy. TLV-TWA and TLV-STEL data extracted from the 2005 Threshold Limit Biological Exposure Indices, copyright 2005 by the American Conference of Governmental Industrial Hygienists (ACGIH).
