Always add the chemical to the greater volume of water, in the enclosed container because of the danger from hot splashes. The reservoir should have a suitable means for releasing the detergent to waste after use. Fit jubilee clips to the joints on the outlet side of the milk pump. The hot caustic wash presents the greatest risk. Keep well away from the plant when circulating the solution.
