FLINTSHIRE parents have been urged to make sure their children are safe after concerns about a potential rising trend in nitrous oxide use.

The Leader reported last year on Operation Blue Sapphire - an initiative to raise awareness about the dangers of nitrous oxide, as well as educating traders about their obligations when it comes to the sale of the gas.

Sgt Emma Prevete, of the Flintshire South police team, said while there had not been an increase in reports of the substance in Flintshire, a "potential rising trend" nationally has prompted talks about "reigniting" Op Blue Sapphire.

She said: "Nationally, some of the kids are moving onto using bigger cannisters and one young lad was hospitalised.

"We are discussing a preventative measure to raise awareness and prevent harm to people, as well as preventing the anti-social behaviour and littering linked to its use.

"We are looking to revisit this operation and we would ask parents and carers to be vigilant of what their kids are buying online.

"The impact of nitrous oxide can be life threatening.

"You're putting a gas in your body which causes a lack of spatial awareness and nausea, and if you're in an environment that is unsafe or dark, there will be a short period of time where you may not be in control.

"You may put yourself in harm's way - for example by rivers or traffic.

"If kids are out using this rurally, there may also be nobody nearby to help.

"I would also reiterate to businesses their obligations under trading standards legislation; it is illegal to sell this to anyone who is not using it for legitimate purposes."
