SPIT and bite guards will be used by Dorset Police officers from December to limit the number of assaults on officers and staff.

When plans for the guards were discussed earlier this year, Dorset Police Federation representative, Sergeant Simon Kempton, said the number of spitting assaults on officers had increased by 500 per cent year on year.

Spit and bite guards are made from a breathable material that goes over a suspect's head and contains a section that prevents the person from spitting.

Strict guidelines apply for the use of the guard. It can only be used on a person who has either spat already or threatened to spit.

Chief Superintendent Colin Searle said: “The introduction of this kit is vital to support officer and staff safety. Biting and spitting is a vile act and the new SBGs will provide additional protection to help keep everyone safe.”

He added: “Dorset Police need to ensure the safeguarding of those in our care who need to be fitted with an SBG, with particular consideration to those who are vulnerable or with mental health needs. This included making sure any option had been robustly medically tested to ensure the safety of those in our care who may be in ill health.”

Dorset Police will now be one of 24 forces who deploy spit and bite guards in operational and detention settings.

The Police and Crime Commissioner for Dorset, Martyn Underhill has previously voiced concerns over the use of the guards.

"The principle that police officers and staff should not be spat at or bitten is beyond dispute; and I respect and accept the decision of the Chief Constable of Dorset, James Vaughan to introduce spit guards across the Force," he said.

"I have, in the past, voiced genuine concerns over the use of spit guards. I am, however, reassured by the Chief Constable that there will be full and comprehensive training for all officers under the College of Policing National Personal Safety manual with regard to the use of the guards and that the guidance in that manual will be strictly adhered to."

An Assaults on Emergency Workers Bill has come into force this month, which doubles the maximum penalty available for assaults on emergency workers, including spitting.
