20 liters of Nalco 7320 was slug fed into the cooling tower basin (volume 272 cu.meters). When adding NALCO 7320 chemical to SA 2 cooling tower, experienced burning sensation to eyes and had strong chemical smell. Although I removed myself from the area immediately, the chemical smell lasted about 30 minutes before I stopped smelling it. I did not require or seek medical attention and passed the information on to other operator to ensure they would take appropriate precautions when adding chemicals to SA 1 cooling tower. Had transported the chemical in cab of pond truck and there was no odour to the concentrated chemical. MSDS sheet Section 9 stated that odour was "mild, disinfectant". Section 8 stated that "Where concentrations may exceed limits given in this section, the use of a full face filter mask or air supplied breathing apparatus is recommended." As the cooling tower is a large space, did not anticipate that any limits would be exceeded. Section 10 of the MSDS -Materials To Avoid - includes "chlorites". As HTH, a powdered additive containing chlorine, is frequently added to cooling water, suspect that the biocide chemical reacted with the HTH producing a toxic mixture. Follow up investigation has been recommended.
