Principles about water management and safety worthwhile to know TIP: To prevent explosions, better check your pool chemical storage: Inorganic Calcium Hypochlorite ( 60 - 70 %) and organic Chlorine ( Trichloro -iso -Cyanuric acid, TCCA, ) the so called “90 % chlorine” look almost the same and can therefore be brought mistakenly together, which can have fatal consequences. Calcium Hypochlorite acts as strong oxidizer and reacts with all organic components, for example with the organic acid, the Cyanuric acid of TCCA. and ignition and / or explosions will occur. Reports have been rarely released about such tragedies, but the author knows that it happens sadly often. Loss of eyesight, severe burns of the torso, limbs and head are common consequences if not worse.
How could it have happened? Have a look how the pool chemicals are stored at your premises. You may wonder that an explosion hasn’t happened yet! Opened containers, often from different suppliers, often without labels on it are often placed next to each other. In accident happens mostly when new or temporary staff clear up the site and fill the chemical powder containers together. The light conditions in dark pump rooms are also not favorable for to distinguish clearly chemicals. ACTION: Buy chemicals only from well managed stores. Make sure that all container are labelled. Separate Acid from Chlorine chemicals. Chemicals must be stored in dry environments ( all too often the pump rooms get flooded! TIP: Buy TCCA as powder, which can be easily distinguished from the granular Calcium Hypochlorite. More on chemical management & safety in next TARA issue and in our POOLASIA Workshop, Chiang Mai
