take these issues into account. These provisions
necessitate an expansion of the system’s monitoring
areas - indices. Aside from analysing the results of
accessibility task implementation or the measurement
of the correct use and effectiveness of operational
arrangements, the supervision should encompass the
improvement of the accessibility culture and analysis
of the awareness of the importance, weight and
consequences of actions and the way they contribute
to the correct use and effectiveness of the AMSII,
including the achievement of the accessibility
objectives. This aspect is one of the most difficult
changes present in the new requirements.
The accessibility objectives should be:
− consistent with the organisation’s accessibility
policy and strategic objectives (where appropriate),
− related to the most important risk areas that affect
the organisation’s accessibility results,
− measurable,
− compliant with the current legal and other
requirements,
− reviewed in terms of their achievement and
changed where appropriate,
− communicated.
The Process Risk Management description also
needs to be verified and updated [6]. Until now,
organisations have only applied mandatory
(according to the Labour Code) occupational risk
management. An organisation should specify and
analyse all operational risks (organisational, technical
and environmental risks arising from the human
factor) important for the type, scope and field of
activity conducted by the organisation identify the
need for cooperation, where appropriate, with other
concerned parties, and to communicate them to its
employees and external entities involved. Specify
fields of accessibility risks arising from its transport
activity, regardless of whether the activity is
conducted by the organisation itself, or by its partners
or suppliers controlled by it. Ensure that accessibility
is taken into account when identifying the
organisation’s business risk and risk management,
and clarify the manner of recognition and resolution
of conflicts between exclusion and other business
objectives. Where appropriate, the employees, their
representatives and external parties involved must be
consulted during the establishment, maintenance and
improvement of the AMSII in relation to specific parts
they are responsible for and in relation to accessibility
aspects in operational procedures. Furthermore, an
organisation should manage the risk of hazards
related to technical measures throughout their entire
lifecycle, i.e. starting at the design stage and ending
with the use stage, and meet the requirements on
human factors throughout the entire lifecycle. At least
the following aspects are taken into account to control
the risk in important cases for the provided
maintenance services:
− determination of maintenance needs to maintain
technical measures in a safe operating condition,
− management of the decommissioning of technical
measures for maintenance purposes,
− management of putting technical measures back
into service,
− management of monitoring and measurement
equipment to ensure its adequacy for the intended
purpose.
An organisation should determine and control
accessibility risks arising from activity commissioned
as part of outsourcing, including activity or
cooperation with partners and suppliers, and use
information referring to investigations intended for
risk assessment review, drawing conclusions to
improve accessibility and, where appropriate, use
remedies or improvement measures [7]. It should also
take into account the need to determine, ensure and
maintain a safe working environment compliant with
the requirements of the current rules of law, especially
the Directive 89/391/EEC (Labour Code).
The process of risk assessment and management
may be based on methods commonly used in different
transport modes (e.g., FMEA, FHA, HAZOP), which
guarantee the fulfilment of necessary steps of proper
risk management: identification, estimation,
evaluation, response, communication, and monitoring
[8-9]. The implementation of recommended corrective
and preventive actions should be continuously
supervised, and their effects should be verified. After
a specified deadline for implementing
control/preventive measures, the process should be
evaluated, and a new risk indicator calculated. If the
risk class for a given hazard exceeds the threshold
adopted, it is necessary to define additional risk
control measures following the strategy adopted. A
person responsible for supervising the
implementation of activities was also assigned. Once
the planned scenario has been implemented, the
assessment body re-examines the risk level of the
hazards. If a satisfactory level is reached, the
procedure is completed. Otherwise, additional actions
are taken.
For transport operators’ risk management areas,
the most used method is FMEA (failure mode and
effects analysis) [7, 10]. Valuation of the hazards
identified for the entire hazard area begins with
determining, on a scale of 1–10, the factors affecting
the hazard, where:
W—probability (possibility) of hazard occurrence,
determined in the range from 1 to 10. The probability
of occurrence is a relative rather than absolute value.
The only way to lower the occurrence rank is to
prevent or control the cause of error posing the
hazard by changing the process.
Z—the probability of hazard detection, determined
in the range from 1 to 10, is an assessment (position in
the ranking) associated with the best control tool
given in the process control tool column. Detection is
a relative assessment within a specific FMEA. As a
rule, to achieve lower ranks, the planned control tool
should be improved.
S—possible consequences of an incident resulting
from hazard propagation, a value between 1 and 10, is
the level of ranking assigned to the most severe effect
for a given type of error causing a hazard to the
power industry.
The risk assessment is based on the product [7]:
R = Z × W × S
The R-value for the risk hazard measure ranges
from 1 to 1000. Hazards with the R number above 121
