Investigation
Introduction
This procedure describes how HSE carries out the process of investigating incidents and complaints: from being notified of the event and deciding whether to investigate, through planning and preparing, conducting the investigation itself, and reporting and recording the outcome.
Purpose
To provide a common, transparent procedure for HSE operational group staff to carry out investigations consistently, and enable HSE to efficiently fulfil its duties under the Health and Safety at Work etc Act 1974
Scope
The procedure covers the handling of all notified incidents by HSE, whether reportable or not, from receipt to completion, including investigation where appropriate; it also applies to the investigation (as opposed to the follow up) of complaints
Policy
HSE’s policy is to conduct investigations in accordance with HSC's Enforcement Policy Statement
For further guidance on this, please see paras 31-32 of:
The selection of incidents for investigation will follow publicised selection criteria. When deciding which incidents to investigate and the level of resource to be used, account will be taken of the:
- severity and scale of potential or actual harm;
- seriousness of any potential breach of the law;
- duty holder’s known past health and safety performance;
- enforcement priorities;
- practicality of achieving results
- wider relevance of the event, including serious public concern.
Exceptionally, HSE may decide not to investigate where:
- there are no reasonably practicable precautions;
- it is impracticable to follow-up/investigate, or
- there are inadequate resources to follow-up/investigate.
Definition
Investigation is a reactive process which includes all those activities carried out in response to an incident or a complaint to:
- gather and establish the facts
- identify immediate and underlying causes and the lessons to be learned
- prevent recurrence
- detect breaches of legislation for which HSE is the enforcing authority
- take appropriate action, including formal enforcement.
An investigation may range from an enquiry by a single inspector about a minor incident or complaint to a large enquiry involving a team of inspectors.
