Indoor Swimming Pool. Respiratory risks of indoor swimming pools can include coughing, wheezing, aggravated asthma, [1] and airway hyper-responsiveness (spasms of the bronchial tubes in the lungs causing coughing and chest tightness). The chemicals used for pool water disinfection can react with organic compounds in the water to create ...
When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...
Shock chlorination is a process used in many swimming pools, water wells, springs, and other water sources to reduce the bacterial and algal residue in the water. Shock chlorination is performed by mixing a large amount of sodium hypochlorite, which can be in the form of a powder or a liquid such as chlorine bleach, into the water.
While chlorine kills most bacteria such as E. Coli in less than a minute, it takes at least 16 minutes to kill Hepatitis A, and the Cryptosporidium parasite can last in the swimming pool for over ...
Firefighters responded to a reported “chlorine spill with possible accidental ingestion” in a “lazy river pool area,” shortly before 5 p.m. on June 24, the Houston Fire Department said in ...
In addition, trichloramine has been detected in the air above swimming pools, [6] and it is suspected in the increased asthma observed in elite swimmers. Trichloramine is formed by the reaction of urea (from urine and sweat) with chlorine and gives the indoor swimming pool its distinctive odor.
A lot of people are not going to be able to find the chlorine tablets they need this season,” said one industry expert. A major chlorine shortage is set to spoil summertime fun in the swimming ...
In swimming pools, chloramines are formed by the reaction of free chlorine with amine groups present in organic substances, mainly those biological in origin (e.g., urea in sweat and urine). Chloramines, compared to free chlorine, are both less effective as a sanitizer and, if not managed correctly, more irritating to the eyes of swimmers.
