You are right, it is about a slug in a bottle, but who put the slug in the bottle, and what was the ruling, keep digging you will come up with the right answer yet.
The following information has been taken from the Management of Health and
Safety at Work Regulations 1999:
Competence in the sense it is used in these Regulations does not
necessarily depend on the possession of particular skills or
qualifications. Simple situations may require only the following:
(a) an understanding of relevant current best practice;
(b) an awareness of the limitations of one's own experience and knowledge;
and
(c) the willingness and ability to supplement existing experience and
knowledge, when necessary by obtaining external help and advice.
More complicated situations will require the competent assistant to have a
higher level of knowledge and experience. More complex or highly technical situations will call for specific applied knowledge and skills which can be offered by appropriately qualified specialists. Employers are advised to
check the appropriate health and safety qualifications (some of which may
be competence-based and/or industry specific), or membership of a
professional body or similar organisation (at an appropriate level and in
an appropriate part of health and safety) to satisfy themselves that the
assistant they appoint has a sufficiently high level of competence.
The issue of competency when working with electrical equipment, is dealt
with in Regulation 16 of the Electricity at Work Regulations 1989. It
states:
Regulation 16 Persons to be competent to prevent danger and injury
No person shall be engaged in any work activity where technical knowledge
or experience is necessary to prevent danger or, where appropriate, injury,
unless he possesses such knowledge or experience, or is under such degree
of supervision as may be appropriate having regard to the nature of the
work.
Guidance 16
The defence (regulation 29) is available in any proceedings for an offence
under this regulation.
The object of the regulation is to ensure that persons are not placed at
risk due to a lack of skills on the part of themselves or others in dealing
with electrical equipment.
"... PREVENT DANGER OR, WHERE APPROPRIATE, INJURY..."
This regulation uses both of the terms, 'injury' and 'danger'. The
regulation therefore applies to the whole range of work associated with
electrical equipment where danger may arise and whether or not danger (or
the risk of injury) is actually present during the work. It will include
situations where the elimination of the risk of injury, ie the prevention
of danger, for the duration of the work is under the control of a person
who must therefore possess sufficient technical knowledge or experience, or
be so supervised, etc to be capable of ensuring that danger is prevented.
For example, where a person is to effect the isolation of some electrical
equipment before this person undertakes some work on the equipment, they
will require sufficient technical knowledge or experience to prevent danger
during the isolation. There will be no danger from the equipment during
the work provided that the isolation has been carried out properly; danger
will have been prevented but the person doing the work must have sufficient
technical knowledge or experience so as to prevent danger during that work,
for example by knowing not to work on adjacent 'live' circuits.
But the regulation also covers those circumstances where danger is present,
ie where there is a risk of injury, as for example where work is being done
on live or charged equipment using special techniques and under the terms
of regulation 14. In these circumstances persons must possess sufficient
technical knowledge or experience or be so supervised etc, to be capable of
ensuring that injury is prevented.
Technical knowledge or experience
The scope of 'technical knowledge or experience' may include:
(a) adequate knowledge of electricity;
(b) adequate experience of electrical work;
(c) adequate understanding of the system to be worked on and practical
experience of that class of system;
(d) understanding of the hazards which may arise during the work and the
precautions which need to be taken;
(e) ability to recognise at all times whether it is safe for work to
continue.
Allocation of responsibilities
Employees should be trained and instructed to ensure that they understand
the safety procedures which are relevant to their work and should work in
accordance with any instructions or rules directed at ensuring safety which
have been laid down by their employer.
Supervision
The regulation recognises that in many circumstances persons will require
to be supervised to some degree where their technical knowledge or
experience is not of itself sufficient to ensure that they can otherwise
undertake the work safely. The responsibilities of those undertaking the
supervision should be clearly stated to them by those duty holders who
allocate the responsibilities for supervision and consideration should be
given to stating these responsibilities in writing. Where the risks
involved are low, verbal instructions are likely to be adequate but as the
risk or complexity increase there comes a point where the need for written
procedures becomes important in order that instructions may be understood
and supervised more rigorously.
In this context, supervision does not necessarily require continual
attendance at the work site, but the degree of supervision and the manner
in which it is exercised is for the duty holders to arrange to ensure that
danger, or as the case may be, injury, is prevented.
