CO level allowed to be displayed in home CO detectors by CPSC 35 ppm = Max 1-hour avg. outdoor ambient CO level allowed by EPA,  also Max 8-hour avg workplace ambient CO level recommended by NIOSH 50 ppm = Max 8-hour avg workplace ambient CO level allowed by OSHA (highest on earth) 70 ppm = Min. CO level for home CO detector alarm, but only if exceeded for 1 to 4 hours 100 to over 1000 ppm = CO level exhaled by smokers while smoking 200 ppm = CO level at which NIOSH recommends immediate evacuation of any workplace 400 ppm = Max CO level for home CO alarm, but only if exceeded for 4 to 15 minutes 800 ppm = CO level allowed from gas ovens range tops (combined) by ANSI’s 1925 std 1200 ppm = CO level NIOSH considers “Immediately Dangerous to Life and Health” 3000 ppm (0.3%) = CO inhaled in DLCO test as part of stan
