Work Instruction 5:
Interviewing





This Work Instruction is concerned with how inspectors should conduct interviews.

It states that:

"whenever possible and if enforcement action is likely, formalise interviews by taking statements at the same visit."

There are six key activities concerned to assist in the conducting of interviews:

KA 1 Preparation for interviews
KA 2 Who to interview/what order
KA 3 General conduct/structure of interviews
KA 4 Notes and recording interviews
KA 5 Use of police interviews
KA 6 Joint interviews with other Enforcement Authorities




Key activity 1

PREPARATION FOR INTERVIEWS


3

Interviews fall into 3 categories:
(1) initial interviews, in which inspectors sound out the potential relevance to the investigation of the knowledge and experience of any individual, in order to identify potential witnesses;
(2) further interviews, in which inspectors explore the knowledge and experience of any potential witness in detail, and which may lead immediately, or subsequently, to the taking of an HSW Act s.20 statement;
(3)

key interviews, for example, interviewing of
(a) senior management, where it appears that a company has a case to answer,
(b) individuals who may have personal liability,
(c) key witnesses in a complex investigation, and
(d) reinterviewing of witnesses.

4 Inspectors should make appropriate preparations before conducting any interview. See Enforcement Handbook - England & Wales Chapter 2 or Enforcement Handbook - Scotland Chapter 2, as appropriate, for guidance on taking witness statements and voluntary statements.

Key activity 2

WHO TO INTERVIEW AND IN WHAT ORDER

5 After initial discussions, inspectors should not interview senior or other managers in depth (unless they are direct witnesses to the accident) until factual matters relating to the accident have been established.
6 Inspectors should plan the order in which they interview witnesses to ensure that the findings and outcome of the investigation are not compromised. They should interview the following first (not necessarily in the order given), so far as is relevant and appropriate
(1) any injured people;
(2) workers with knowledge of the particular incident being investigated;
(3) other workers who have knowledge of the same or similar work (on the same day, or before or after the incident), and who can confirm, or contradict, any shortcomings which apparently led to the incident;
(4) any trade union and safety representatives with relevant knowledge; and
(5) other witnesses to the incident, eg members of the public
7 Next, inspectors should interview supervisors and similar lower-level management, who have background knowledge and may also be able to describe systems of work and other steps taken to ensure safety. Question them concerning any instructions they had been given about the job and the instructions they had given to those carrying out the work activity. The interview should try to determine whether they were aware of actual as opposed to correct practices. Depending on what information such interviewees provide, reinterviewing of workers etc may be necessary.
8 Inspectors should then assess information obtained from employees, if necessary with the assistance of specialist or other expert help. This will clarify the information they can gain from further questioning, before they interview managers.
9 Finally, inspectors should interview senior managers, directors and individual dutyholders who can make admissions either in relation to their own or a companyâs liability.
10 Inspectors may not decide, until a late stage in an investigation, to collect evidence with a view to legal proceedings. Observing the hierarchy of interviewing described above will help to ensure that the outcome of any investigation is not unwittingly prejudiced before they reach such a decision.

Key activity 3

THE GENERAL CONDUCT AND STRUCTURE OF INTERVIEWS

11 Inspectors should ensure they conduct interviews efficiently, and with the aim of eliciting all relevant information within the knowledge of the interviewee. They should pay due regard to the rights, dignity and individual circumstances of the interviewee.
12 For guidance over the structure of an interview see the appendix to this WI. In England and Wales, see also Enforcement Handbook - England and Wales on when the interview may need to be carried out in accordance with PACE. When interviewing young persons, see Enforcement Handbook - England and Wales Chapter 2 or Enforcement Handbook - Scotland Chapter 2 as appropriate.
13

Inspectors should use their discretion not to conduct or continue a detailed interview if this would be an inefficient or ineffective use of resources (for example, because there is no evidence of a breach of relevant legislation), or if continuation of the investigation would be of no benefit to FOD or HSE. Such a decision must be appropriate and justifiable in the circumstances.

Key activity 4

NOTE-TAKING AND RECORDING OF INTERVIEWS


14 Inspectors should take accurate, contemporaneous notes of interviews, with sufficient detail to facilitate report-writing and, where relevant, statement-taking. The notes should briefly but accurately record all Îrelevant detailsâ and Îkey findingsâ.
14 Relevant details include the name and position of the interviewee.
16 Key findings are the essential facts central to the witnessâs evidence, including those supporting and those contradicting any reasonable line of enquiry. It is extremely important that inspectors are not selective in their findings and remain impartial. They should base decisions as to causation and responsibility only on facts that can be established beyond reasonable doubt.

Key activity 5

USE OF POLICE INTERVIEWS


17 In the case of work-related death(s) the police will make an initial assessment of whether the circumstances might justify a charge of manslaughter or culpable homicide at which point they will begin their investigation. Once an HSE fatal accident investigation has commenced, evidence may come to light to indicate an offence of manslaughter or culpable homicide has been committed.
18 In such circumstances, inspectors should make early contact at an appropriate level to establish lines of communication so that both parties are kept informed of events and subsequent enforcement decisions are not compromised.
19 Inspectors should be aware that under both scenarios interviews/statements obtained by the police may be provided to HSE inspectors to facilitate their enquiry and vice versa. For further guidance including matters relating to disclosure see OC 165/8 Work-related Deaths: Liaison with the Police and Crown Prosecution Service.
20 In cases of horseplay, wilful damage to equipment or violence to employees, the police could have an enforcement interest and could become involved. Once again their interview/statements could be used in any HSE investigation should we later decide to pursue HSW Act breaches. Choice of offence to pursue may depend on seriousness of breach and available penalty. See FIC LP 237 for guidance.
21 Another possible occasion when police interviews may be used is when road traffic accidents occur in places such as bus depots or air side of airports or other workplaces where the public have access. Interviews obtained by the police for their purposes may be of use to HSE if HSW Act issues are pursued.
22 Inspectors should be aware that an organisation cannot be prosecuted for the same offence by 2 enforcing authorities. However, often with RTA issues, the police prosecute the individual driver while HSE could pursue the organisation if appropriate. Also, if the police/CPS decide to drop a charge, eg manslaughter, then HSE can proceed. In Scotland, the Procurator Fiscal makes the decisions.

Key activity 6

ARRANGEMENTS FOR JOINT INTERVIEWS WITH OTHER ENFORCING AUTHORITIES


23 In England and Wales, when police or other enforcing authorities are to conduct PACE interviews or witness interviews which may be of interest to HSE, inspectors should make contact prior to the interview. Inspectors will then have the opportunity to be involved in the planning stage so that questions relating to health and safety issues can be included. (Often HSE inspectors will not be allowed to attend for fear of oppression in terms of numbers present.) Be aware that such PACE interviews are often conducted at an early stage of an investigation by the police so be prompt in getting involved.
24 Depending on the circumstances, joint interviews of witnesses may be of benefit when questions involving technical detail need to be put to an interviewee. Often, however, it is not possible to attend all interviews if the investigation is very large. The police will have more resource to carry out interviews in such circumstances.






APPENDIX
INTERVIEW STRUCTURE

1 Initial introductions, explain your powers etc, wish anyone to be present? Consider indicating that you may later wish to take a statement. Confirm status of individual before commencing interview. Identify reporting arrangements.
2

Briefly enquire about general issues relating to the incident before moving on to address specific details. Plan and adapt in the light of information obtained from the interviewee.

(1) Age, if the interviewee is a young person; date of leaving school; date of birth. Presence of adult.
(2) Length, nature and status of employment by whom. Role and title. Pay arrangements, particularly if employment status in doubt.
(3) Experience, qualifications and general training.
(4) Instructions given to the interviewee (if any), any arrangements to supervise them.
(5)

Their knowledge of the circumstances of the incident, or conditions/events before or after the incident. Use of a sketch may help. Ask them to concentrate on a specific issue for example:

(a) where they were in relation to the scene of the incident
(b) what they saw, heard, smelt or even felt;
(c) environmental conditions at the time (noise, lighting, temperature, wind) and whether these affected their ability to see or hear what happened, or were relevant to the circumstances of the incident;
(d)

what they know of the condition of any:
(i)

plant, machinery or equipment involved, or guarding provided;

(ii) existing damage;
(iii) controls/gauges;
(iv) electrical or other supplies etc;

(e)

their knowledge of
(i) the way things are done normally;
(ii) safe systems of work/permits;

(v) the awareness of management of events leading up to the incident

(f) their knowledge of documents, eg safety policies/method statements, safety plans/the significant findings of risk, COSHH, manual handling or other relevant assessments;
(g) schedules/schemes of inspection or examination, arrangements regarding competent persons, H&S advice and preventive maintenance of plant and machinery.
(6) Knowledge of any relevant issues prior to the occurrence of the incident. Had they done similar or the same work? Did they know of, or had they reported any problems prior to the incident, ie previous similar near miss incidents? How long had problems existed? Is there evidence that others were at risk in addition to the IP before, during or after the incident?
(7) TU or employees complaints/involvement.
(8) What responsibilities do they have specifically related to health and safety? Is their performance on health and safety measured in any way. How else does the dutyholder measure health and safety performance (site inspections etc)?
(9) Is there a health and safety committee? How often does it meet? Aware of what was said?
(10) Action taken after the incident, eg any changes to systems of work.
(11) Summary and conclusion: offered the opportunity to add anything they think is relevant that has not been discussed.
(12) Decide to take statement? Consider which breach to prove. Any defences to overcome, and what exhibits and how to introduce them.
(13)

At the end of the interview, thank the interviewee, and tell them in general terms what further action we will take to complete the investigation.
