Chlorine Dioxide Generation Chemical Safety and Environmental Awareness
For the majority of bleach plants in operation today, chlorine dioxide is produced by combining sodium chlorate, methanol, and sulfuric acid. This course discusses the hazards each of these chemicals present as well as the protective measures that should be taken while working with or around them.

Sample Video Transcript
Chlorine dioxide storage poses a significant environmental and safety threat. There are several features needed for the safe storage of chlorine dioxide. The tank should be insulated to keep chlorine dioxide cool. An explosion relief lid on the top of the tank in case an explosion occurs. Sweep air is added to the top of the storage tank to dilute the concentration of vent gas sent to the scrubber. A floating cover in the tank can reduce the amount of ClO2 gas present at the top of the tank. This can allow higher storage concentrations which can reduce tank size, energy for generation and cooling, and the amount of steam needed in the bleach plant.
