CARBON DIOXIDE CAS number: 124-38-9 Molecular formula: CO 2 TLV–TWA, 5000 ppm (9000 mg/m3) TLV–STEL, 30,000 ppm (54,000 mg/m3) 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

PELs are 8-hour time weighted averages (TWAs) unless otherwise indicated. OSHA enforces these limits under section 5 (a) (2) of the OSH Act. In addition to the values listed in this table, the Z tables in 29 CFR 1910.1000 list skin absorption designations. (c) The CAS number is for information only. Enforcement is based on the substance name.

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.

A TLV-TWA of 5000 ppm (9000 mg/m3) and a TLV-STEL of 30,000 ppm (54,000 mg/m3) are recommended for occupational exposure to carbon dioxide. The recommended values are intended to minimize the potential for asphyxiation and undue metabolic stress.

The American Conference of Governmental Industrial Hygienists (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.

The American Conference of Governmental Industrial Hygienists (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 10 minutes.

May 10, 2024 · What are other names or identifying information for carbon dioxide? Appearance: Colourless gas. Canadian TDG: UN1013, UN2187. What is the WHMIS classification? According to the Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) carbon dioxide (gas) can be classified as: Gases under pressure - Compressed gas.

GIH) threshold limit values (TLVs) are shown in the table below. Although the TLVs are intended for occupational daily work shift exposures over an entire working lifetime, the current ACGIH TLV-time-weighted average (TLV-TWA) for CO2 (5,000 ppm) is based on the lack of inhalation toxicity data in humans at this level and the
