Why should you use BS EN 901 - Water intended for human consumption - Sodium hypochlorite?
Sodium hypochlorite is a compound that can be effectively used for water purification. It is used on a large scale for surface purification, bleaching, odor removal and water disinfection.
BS EN 901 provides you with the minimum purity requirements for sodium hypochlorite used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product. Depending on the raw material and the manufacturing process other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities.
Sodium hypochlorite’s more use would be dangerous for health, that can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, severe shortness of breath, headache, dizziness, nausea, and vomiting. Therefore, BS EN 901 provides the rules relating to the safe handling and use of sodium hypochlorite.
BS EN 901 provides you guidance on test methods that include sampling and analysis. BS EN 901 guides the labelling, transportation, and storage of the product so that the purity is not affected. BS EN 901 helps to avoid potential adverse effects on the quality of water intended for human consumption.
