  • Why All The Hype About Chlorine Gas Safety
    are incidents with the handling of virtually every hazardous chemical known to mankind But with chlorine gas these are very isolated incidents and most importantly no one dies It can be very unpleasant and preventive hospitalization may be necessary for observation but in the end personnel return to their jobs in virtually all cases And even more importantly there has been no loss of life mass evacuations or mass hospitalizations as a result of chlorine gas leaks at water and wastewater treatment facilities in the USA in more than 20 years where 150 lb chlorine cylinders were in use This is the vast majority of treatment facilities Where one ton containers were in use a very few incidents called for erring on the side of caution and people were evacuated from an area around the facility until the leakage was brought under control But again no loss of life One might assume from the public outcry that has been raised recently in favor of these so called Inherently Safer Technologies that they are incident free and that no one has been injured during their use Nothing could be further from the truth The other forms of chlorination detailed above have all had their significant accidents and on a very regular basis Improper mixing of chemicals has repeatedly resulted in large scale releases of chlorine gas from sodium hypochlorite treatment facilities that HAD NO CHLORINE GAS CONTAINERS ON SITE Large fires and explosions have rocked calcium hypochlorite storage facilities with the resultant toxic clouds carried over large areas The media reports state that chlorine gas was released but rarely if ever do they mention that the cause was anything other than chlorine gas containers A large water treatment facility in Michigan had used gas chlorination for many decades and had an enviable safety record Concerns by city officials about the storage of gas chlorine containers led them to change the facility over to sodium hypochlorite Very large storage tanks were installed in the facility for the bleach A tank truck delivering aluminum sulfate for part of the treatment process accidentally pumped the chemical into one of the bleach tanks and 12 workers went to the hospital with chemical inhalation distress Countless cases of personnel accidentally spilling or adding the wrong chemical around bleach storage areas results in hundreds of injuries every year Hydrogen gas is a significant explosion hazard and is produced as a byproduct of some of these on site generation processes offered up as safer technology The reality is that there have been many many incidents in which these generators failed to properly vent the excess hydrogen which resulted in explosions of varying dimensions One actually lifted the roof off of a storage building And people have been injured A large sodium hypochlorite generator at a treatment plant in West Palm Beach FL exploded due to a failure of the hydrogen venting system and peppered the walls of the chlorination room with plastic shrapnel Luckily this happened in the very early morning hours when no one was present in the room This was the SECOND incident at this same plant Every treatment technology has some risks There are no magic wands that will whisk away the potential for injury while at the same time offering the public safe drinking water and wastewater free of dangerous pathogens Chlorine in all of its forms continues to offer us the most affordable and most well understood means of eliminating water borne diseases Both government as well as private researchers in addition to health agencies and water treatment professionals acknowledge that chlorination is a vital part of our water infrastructure and should remain so into the foreseeable future Even the newest limited application treatment processes still require some chlorination to protect a public water distribution system from contamination after the water leaves the treatment plant Follow The Money Knowing all of this there is still a movement to eliminate or reduce the use of gas chlorination One really has to wonder about the motivation for such zealotry It will cost consumers rate payers a lot more money because there is just no alternative as economical as gas chlorination There is no other form of chlorination that is as trouble free and easy to maintain There is no justification based on the safety record Replacing gas chlorination with large sodium hypochlorite installations has been a movement that goes back to the 1960s with very little success Beginning in the early 21 st century the propaganda machine of certain chemical interests began to beat this drum in earnest Large bulk bleach suppliers started to offer seemingly irresistible package deals whereby they would supply all of the feeding and storage equipment for free if treatment plants would only sign a long term contract that guaranteed the bleach supplier a monopoly on the chemical supply Sometimes other chemicals were tied into the deal Some of these suppliers were also in the chlorine gas supply business which was not as profitable These suppliers make far more profit selling bleach than they do selling chlorine gas As a famous investigator once said follow the money By 2006 many municipalities that had switched to bleach under these arrangements were having second thoughts Their budgets were being eaten up by very high chemical costs as well as equipment failures high maintenance and operator complaints Still those chemical suppliers and even some chemical feed equipment suppliers were spreading rumors that the U S Environmental Protection Agency was going to outlaw gas chlorination and that legislators and regulatory agencies would limit the amount of chlorine gas allowed on site at a treatment plant That kept most customers in line They didn t want to switch back to gas chlorination only to be forced to give it up even though it made very good sense from both a financial and technical perspective In many cases the decisions were being made by town fathers who while possibly acknowledging the financial realities had no idea of
