Asbestos (Prohibitions) Regulations 

7 

The Asbestos (Prohibitions) Regulations prohibit all new uses of all forms of asbestos.  All of MOD 

must meet the requirements of the Prohibitions Regulations and be committed to eliminating all uses of 

asbestos in defence systems wherever practicable and as soon as possible.  MOD Instructions on 

compliance with the Prohibitions Regulations and MOD s own elimination programme are given in 

Leaflet   Asbestos Prohibitions, and any plans to continue using asbestos must comply with those 

instructions. Failure to comply risks prosecution. 

NOTE 

The Prohibitions Regulations also include giving away asbestos for considerations other than 

money, and apply equally to second hand asbestos.
