Setting of the toxic gas alarm threshold for bromine gas
Thread Content
Dear seniors, how should the alarm threshold for bromine, a toxic gas, be set? I calculated using the formula provided in specification 50493; the threshold value for level 1 alarm is: 0.045 ppm ； The secondary alarm value is: 0.09 ppm. I’m not sure if it’s right or not
How did you calculate it? According to the table, 0.3 mg/m3 should translate to 0.084, right? But there is also a corrigendum for 50493 itself:
Your correction sheet is correct, but the “meeting minutes” listed on it seem to be invalid, right? Although no company wants to do this, the scope is too large
