Chlorine and muriatic acid
Mixing bleach, or sodium hypochlorite(NaClO) with muriatic acid(HCl) will liberate chlorine gas, which is absolutely harmful, and a severe irritant to eyes and nasal passages and also the lung area even in smaller amounts.
The reaction goes as follows:
HCl + NaClO → NaCl + HClO
If there is too much HCl this 2nd response can occur:
HCl + HClO → H2O +Cl2
Using this, the overall effect is:
2HCl + NaOCl → H2O + NaCl + Cl2
Chlorine Gasoline Inhalation:
wheezes, rales, and/or abnormal upper body radiographs are present.
More seriously affected individuals may experience acute lung damage (ALI) and/or intense breathing distress syndrome (ARDS).
Very First Helps:
0.5 ppm, 8 hour time weighted average.
11.0 ppm, 15 moment short term exposure limit.
Prompt activity is vital. Get rid of the exposed individual fresh air and summon healthcare help straight away.
If respiration features ceased, start artificial respiration. Trained employees should provide air asap.
Eliminate contaminated clothes. If garments is frozen to epidermis, thaw very first before getting rid of. Rinse location for at the least 30 minutes. Clean skin with water and soap. Get medical attention straight away.
