This blog aims to cover:

  • Security fixings for authorised access
  • Reducing Stash points
  • BioCote® protection

Security Fixings For Authorised Access

For cleaning and maintenance, specifiers should opt for an anti-ligature ventilation grille that provides a secure surrounding, allowing for authorised access only.

This will provide essential tamper-proof protection to reduce risks of improvised weapons and ligature risks.

It also ensures that cleaning and maintenance can be optimised to provide a hygienic solution for offenders.


Reducing Stash Points

With high suicide rates and bullying in YOI’s, articles have found that anti-ligature ventilation grilles can be used as stash points for weapons or blades. Stash points also can be used to smuggle illegal goods.

Cell searches are characterised by two basic types. One type is by a routine cell search and the other is with a routine-plus cell search:

  • A Routine search is a level- A rub-down search and a cell search, with a metal detector
  • A Routine- Plus search is a full body search and may also involve a property record check, in addition to a cell search

Despite the level of search that takes place, contraband such as drugs and mobile phones continue to be an area of concern in YOI environments in the UK.

To ensure stash points are minimised, it’s important to utilise a small ventilation grille to make it difficult for offenders to stash contraband within the ventilation system.

Optimising Hygiene

When offenders ‘dirty protest’ or willingly choose to urinate or defecate without the use of appropriate facilities, it can pose a significant health risk to other’s who are subjected to it.

Tuberculosis, HIV, and Hepatitis C are just some of the risks to YOI staff and other offenders during a dirty protest where bodily fluids, including blood and faeces, are smeared across cell walls or even communal areas.

It’s therefore essential that appropriate cleaning practices are carried out safely and effectively.
