Service Details

The term 'Pressure Vessel' is a general term used by Health and Safety to describe compressors, autoclaves and their associated pipe work and safety devices.

The safe operation, maintenance and servicing of these units is essential to the efficient running of the practice which in turn will form the basis of compliance to the Pressure Systems Safety Regulations 2000, the Pressure System Safety Regulations (Northern Ireland) 2004 and the Safety, Health and Welfare at Work (General Application) (Amendment) Regulations 2012 Pressure Systems (SI No: 445 of 2012)and the Provision and Use of Work Equipment Regulations (PUWER) 1992.

Why do I need a Pressure Vessel Inspection?

All autoclaves and compressors must have a Written Scheme of Examination prepared for each vessel by a competent person. Employers must ensure that all work equipment is safe and in good working condition and that each vessel is inspected at regular intervals as specified on the Written Scheme of Examination. A written report must be provided at each inspection detailing the condition of the vessel/s

Each vessel must be serviced and maintained in accordance with the manufacturers' recommendations and records of servicing and inspection must be kept in order to demonstrate compliance.

All members of staff must be fully trained in the operation of autoclaves prior to use.

How often do I need my Pressure Vessel inspecting?

Each Vessel must be inspected at regular intervals as specified on the written scheme of examination.

How long will a Pressure Vessel Inspection take?

It usually takes 45 minutes to inspect a Compressor or Autoclave.

How much do we charge?

The first PVI is charged at £140+vat for members and any extra PVI's at the same location will be charged at 50% discount.

DD Members also benefit from free Annual Pressure Vessel Insurance, whilst holding a valid DD Membership. Insurance runs from the date of inspection for all compliant pressure vessels.
