What is the threshold limit value of co?

The threshold limit value (TLV) for carbon monoxide (CO) is typically set at 25 parts per million (ppm) for an 8-hour workday, according to the American Conference of Governmental and Industrial Hygienists (ACGIH). For shorter exposure durations, the TLV can vary, with a ceiling limit of 200 ppm recommended for 15 minutes. These values are designed to protect workers from the harmful effects of CO exposure, which can include headaches, dizziness, and more severe health issues at higher concentrations. Always refer to the latest guidelines and regulations for the most accurate and updated information.
