The firm's defence business appeared at Oxford Crown Court on 8 September following an investigation by the HSE. It was fined £33,000 and ordered to pay costs of £17,936.
An asbestos survey undertaken in the boiler room at an MOD base in Arncott, Bicester, in early 2005, found that the whole room was considered to be contaminated with asbestos and recommended that access to the room should be restricted until it was removed.
The company pleaded guilty at a previous hearing, on 11 June at Banbury Magistrates Court, to contravening regulations 4(8)(c), 6(1)(a) and 10(1)(a) of the Control of Asbestos Regulations 2002. The offences were committed at the Oxfordshire MOD site between 23 May 2005 and 30 September 2006.
HSE inspector for Oxfordshire, Matthew Lee, said: "Around 4,000 people die each year from past exposure to asbestos and the material may be present in any building built before the year 2000.
"It is therefore essential that duty holders and facilities managers are aware of the risk it still poses and their responsibilities in managing it.
"Facilities managers are key to ensuring that effective management systems are in place to protect workers and to ensure that duty holders meet their legal responsibilities."
