The Health & Safety Executive has introduced it's 2018 revised guidance HSG179 "Health & safety in swimming pools". The guidance highlights the need for pool operators to take account of the DSEAR (Dangerous Substances & Explosive Atmospheres) regulations when using certain types of pool chemicals. Dangerous substances are any substances used or present at work that could, if not properly controlled, cause harm to people as a result of a fire or explosion. Such chemicals used in pool water treatment include, for example, calcium hypochlorite, trichloroisocyanurates and bromochlorodimethylhydantoin. DSEAR risk assessments must be carried out by trained/competent persons.
Chemical incidents of any type in public buildings pose a significant health & safety risk to facility staff and users alike, due to fact that fumes, gases and dusts are often very difficult to contain and can spread quickly to effect potentially large numbers of people who may be in the vicinity. The administrative and financial burden of COSHH, DSEAR and other work related regulations compliance highlights the benefits of careful consideration when it comes to choosing water treatment chemicals.
Our Hyprolyser 280-8500 electrochlorination systems, which produce a non-hazardous (<1% chlorine) sodium hypochlorite solution on-site, have been independently HAZOP reviewed and assessed against Hazardous Area Classification BS EN 60079-10-1:2015, with a resulting "no hazardous zones" classification. Using only salt, water and electricity to generate sodium hypochlorite on-site, the Hyprolyser system eliminates the delivery, handling and storage of hazardous chlorine chemicals, creating a low-hazard plant room area whilst also reducing risks to facility patrons.
