Pool Safety: Chloramines – Safe Work Practices

Chloramines Overview

Swimming pools, waterparks, hot tubs, and spas are popular palces for playing, exercising and relaxing. Due to British Colubia’s varied climate and people’s desire to swim or soak year-round, many of these faciities are located indoors. Various disinfectants including chlorine, are used to kill pathogens (viruses, bacteria, parasites, etc.) in the water. Chlorine interacts with material from bathers (sweat, urine, sunscreen, cosmetics, etc.) to form chemical by-products such as chloramines.

Chloramines have been associated with upper respiratory and eye irritation. They may also lead to longer-term health issues such as asthma. In order to reduce their workers’ exposure to these chemicals, employers need to monitor and maintain water quality at these facilities. Employers should also remind people who use the pool to shower before entering the water and to use proper washroom facilities.
