Chlorine gas sends two to hospital The safety and cleanliness of public swimming pools are regularly taken for granted by members of the swimming public. And rightly so. In a world of uncertainty this is a given on which society can lean; it is proper to assume the community pool down the street is treated with the appropriate disinfectants.
Sterilizing pools with calibrated chemical doses is a well regulated and safe practice repeated countless thousands of times a day across the country. Standard operating procedure requires that two specific liquid chemicals be piped separately into the water: sodium hypochlorite for residual disinfecting and hydrochlo- ric acid to achieve the proper pH balance.
The system works fine as long as these two chemical agents don’t directly come in contact with each other. But what happens when these chemicals mix?
A Dangerous Mishap “Here at the Laramie Community Recreation Center we have two indoor pools - a leisure pool and a lap pool,” said Paul Harrison, department head of the Laramie Parks and Recreation Department. “Our liq- uid sodium hypochlorite and hydrochloric acid are stored in two large separate tanks. Each week the maintenance staff has to transfer barrels that we receive from shipment to storage tanks housed in an adjacent, sealed room. These chemicals are then auto- matically fed into the pools.”
“This past winter two employees involved in the chemical transfer inadvertently put a small amount of sodium hypochlorite solution in the hydrochloric acid tank,” continued Harrison. “They immediately dis- covered this was wrong, vacated the area, called for assistance, and eventually were transported to the hospital for observation and treatment.”

Wrong indeed. A strong vapor was rapidly filling the small storage area, burning their eyes and lungs; they were wise to flee the scene. Understandably, given the circumstance, the employees left the hydrochloric acid tank unsealed and closed the door to the storage area on their way out.

flict. According to the Centers for Disease Control, chlorine gas exposure can lead to “nausea and vomiting, burning pain, redness, and blisters on the skin… difficulty breathing or shortness of breath may appear immediately if high concen- trations of chlorine gas are inhaled, or may be delayed if low concentrations of chlorine gas are inhaled in the lungs (pul- monary edema) within 2 to 4 hours.” For these two employees on this one morning, there was no fun to be had at The Laramie Community Recreation Center.
