Statutory Requirements And Introduction
Risk assessments, here in Ireland, like most other European
Member States, are a statutory requirement.
Under Regulation 10 of the Safety, Health and Welfare at Work
(General Application) Regulations of 1993 [SO 44 of 1993], it
is the duty of the employer, in preparing their safety statement,
to be in possession of an assessment in writing of the risks
to safety and health of the work place.
These risks are to include any, which put groups of employees
at unusual risk and to implement controls that will protect
the employees against such risks. These controls are to include
any protective equipment to be used.
Under the Machinery Directive 98/37/EC manufacturers of equipment
or their authorised representative in the European Union, must,
under Article 8(2) (A), (b) and (c) draw up a Technical Construction
File, provided for in Annex V.
A specific component of that Technical Construction File is
a description of methods adopted to eliminate hazards presented
by the machinery, i.e. a written risk assessment.
At the time of going to press, there were no statutory duties
on the manufacturer of machinery to supply the end user with
such risk assessment, the only requirements were under Annex
I, Section 1.7.4 for machinery, to be accompanied by instructions
for use of the machinery throughout its life cycle.
The life cycle of work equipment include: -
* Transportation
* Assembly
* Commissioning
* Putting into Service
* Operation
* Maintenance
* Adjustments
* Dismantling
* De-Commissioning
It is worth noting that ALL machinery, on being out into service,
must be accompanied by a translation of the instructions in
the language of the country in which, the machinery is to be
used AND by the instructions in the original language.
Other directives placed further duties on employers in relation
to the safe use of work equipment and these have been implemented
into National Legislation which, provides for the employers
to ensure that: -
- Employees are made aware of safety and health risks relevant
to them, even if they do not use the equipment and when the
safety of equipment depends on the installation conditions,
that
- An initial inspection is carried out after installation
and before it is first put into service and
- That an inspection is carried out after assembly at a new
site or in a new location
The results of these inspections are to be recorded and kept
available for inspection by inspectors of the Health and Safety
Authority for five years.
This then is a further example of another statutory requirement
for a risk assessment of the work equipment.
A final requirement for risk assessments from Council Directive
2001/45/EC has been implemented into National Legislation under
the Fifth Schedule, Para 1 (3)(d) of the Safety, Health and
Welfare at Work (General Application) (Amendment) Regulations,
2001 [SI 188 of 2001].
“Control shall be safe and shall be chosen marking appropriate
allowances for failures, faults and constraints to be expected
in the planned circumstances of use”
The only method choosing control system is assessing the dangers
that exist from its failure and this is a risk assessment as
described in EN 954-1: 1996.
There is not another topic or area within machinery or work
equipment legislation that has been replicated statutorily several
times than that of risk assessment and it is for that reason
will continue through all of its chapters to bring the message
home to manufacturers and users of machinery, the necessity
to carry out comprehensive and, as far as possible, objective
risk assessments.
Objectivity is the ideal application in risk assessments, however,
humans vary and therefore subjectivity creeps into the equation
when attempting to establish a level of risk. In trials using
twelve people of different vocations using the ‘What If’ and
‘Hazard Risk Number’ (HRN)’ approached the group achieved is
nine of twelve applications, the same result.
Whilst other safety practitioners may prefer different risk
assessment approaches, the author feels that a 75% agreement
between groups is an acceptable common train of thought and
most certainly a device for a harmonised approach to risk assessment.
On many occasions the author has been asked ‘where do you draw
the line?’ and the answer will always be the same, i.e. the
risk assessment must look logically at what is foreseeable and
what is not, for example, it is foreseeable that a grinding
or cutting operation on a non-metallic material may cause dust
but the probability of a hardwired emergency stop system failing
is small.
Risk assessment is about applying common sense to a system
of work rather than trying to second-guess the future. As human
beings, we may miss some factors that could arise from operating
machinery and the risk assessor should not be overly concerned
that this omission may result in an injury to the operator for
the probability is, that by carrying out a risk assessment you
have done all that is reasonably possible to implement controls
that will either reduce the likelihood of the hazard or more
preferably eliminate it altogether.
JGMA can carry out various types of risk assessment that will
satisfy all legislative requirements.
