Abstract Human experiments on 6 male volunteers to establish maximum allowable concentrations for carbon monoxide on short-term exposure. After 10min exposure to concentrations of 600mg/m3 and especially of 800mg/m3, initial symptoms of light poisoning (disappearing after 24 hours) were observed. Objective signs of carbon monoxide poisoning develop earlier than subjective symptoms: increasing carboxyhaemoglobin levels in blood (up to 10%), decreasing adaptive capacity of the cardiovascular and respiratory systems and increasing times of simple sensorimotor reflexes which indicate disorders in the nervous system. The maximum allowable concentration of carbon monoxide on one-time exposure for 10 minutes should not exceed 600mg/m3.
