1. The document discusses two methods for assessing staffing arrangements: CRR 272/2001 focuses on physical assessments using decision trees, while RR 292/2004 uses "ladder assessments" to evaluate individual and organizational factors.
2. Key principles from RR 292/2004 include ensuring supervision is a management function, supervision influences team performance, supervisors need resources and opportunities, and contractors require proper supervision.
3. Common issues found are overreliance on informal training, inadequate refresher training, distractions in control rooms, and failing to consider human factors when automating. Problems with changes often stem from financial drivers and a lack of understanding impacts.

Getting the numbers right
Staffing assessments and supervision
2. How do you know if you have the right
number of people?
Routines are getting done
Not had a major accident
Everyone is coping
Comparable with others
But could you get by with less?
3. Canât look at staffing in absolute
numbers
Batch vs continuous
Simple vs complex
Manual vs automatic
Specialist vs commodity
Single site vs global business
4. Changes across the industry
New technology
More automation
Less people
Less layers of supervision
Jobs have changed
More passive
More lonely
More responsibility
Organised differently.
5. Two methods developed as HSE
research projects
CRR 272/2001 - Assessing the safety of staffing
arrangements for process operations in the
chemical and allied industries
Energy Institute User Guide 2004
RR 292/2004 - Different types of supervision and
its impact on safety in the chemical and allied
industry.
8. Self-managed, multi-skilled teams
Inherent strengths:
Less âlayersâ improves communication within teams
Increased workforce involvement
Team members have more variation
Inherent weaknesses:
Lack of leadership
Poor communication external to the team
Responsibilities less well defined & understood
Higher training burden to maintain competence.
9. If you take the supervisor away,
supervision still needs to happen
Defining overall team workload
Allocating day-to-day work
priorities
Allocating manpower for daily
tasks
Communicating operational
information
Problem solving/decision
making
Identifying competence
requirements for tasks
Assessing training
requirements for team
Measuring team performance
Carrying out appraisals
Implementing first-level
discipline
Investigating incidents
Maintaining/updating
procedures
Providing leadership in
emergency situations
10. About the method
Acknowledges different methods of delivering
supervision
Assists in developing safer forms of supervision
Useful when changes are being made
Assists HSE inspectors in carrying out
inspections
Brings issues out into the open
Helps verbalise how supervision is delivered in
practice
Identifies 5 Safety Assessment Principles (SAP).
11. SAP1 - Supervision is a critical
management function
This must be reflected in an organisationâs
safety management system
Level of rigor commensurate with risk
Prioritised
Same as other elements of equal risk
POPMAR
Policy, organisation and planning
Measurement, audit and review.
12. Counterbalances

teams more
likely to deal with
problems locally
than refer up

command & tiers
of responsibility
13. SAP2 - Supervision has a key influence
on the way teams perform
Method of delivery must be suitable for the team
Arrangements must ensure all elements of
supervision are performed
In traditional teams they may all be performed by one
person
In modern teams this is distributed
Everyone must understand how the team
functions, including delivery of supervision
Includes team members, management etc.
Its importance/priority must be clear.
14. SAP3 - Individuals with supervisory role
must have resources & opportunity
Time to carry out their role
Interaction with the people they are supervising
Opportunity
Skills
Respect
Experience in supervising
How does someone learn?
Continual improvement
Operational knowledge.
15. SAP4 - Supervision of contractors must
be properly managed
Can have a significant impact on health and safety
performance
Need to understand why contractors are being
used
Arrangements to address all circumstances
Short vs long-term contractors
Different tasks
Different activities (e.g. major shutdown)
Both sides need to understand and participate
Contracting and operating companies.
16. SAP5 - Organisation must ensure good
leadership in emergencies
Leadership not supervision
Setting direction and providing support
Less direct control - groups work autonomously
Critical for effective and efficient response
Roles clearly defined and understood
Also for deputies
Reliance on training, refresher training and
emergency exercises.
17. Staffing assessment â CRR272
Challenges whether you are likely to have
Enough people
With the rights skills
Who are able to work together
To successfully deal with high demand situations
The âphysicalâ ability to detect, diagnose and
recover from scenarioâs in time to prevent
accidents
Management and organisation in place to make
sure arrangements are sustainable.
18. Assessment Methodology
Physical assessment
Consider high demand
situations
Decisions trees
Pass/fail
Ladder assessment
Individual and
organisational factors
How high can you climb?
Top rung considered to be
industry best practice
YES
YES NO
NO
19. Assessment of physical arrangements
Are people where they need to be?
To hear alarms, to read displays
Are there enough people around?
Will stand-by operators be able to leave their own units
Will off-site staff travel in in enough time
Can people do their tasks in the time available?
Can field operators get from place to place in time
Will the communications be reliable?
Will the batteries last
Eight decision trees provided to assess the adequacy of
physical arrangements
20. Is Control Room (CR)
continuously manned?
Yes No
Does the CR operator go into the field?
What is the maximum time
the CRO is away from CR?
Mins.
Where does the CRO go?
Define:
Is it more than the minimum
time it takes to develop an
unrecoverable scenario?
Yes No
Yes No
21. What happens if the CRO gets retained e.g.
treating a process problem, or he falls over?
What is the primary way that a process alarm or
trip is detected when he is away?
FAIL
Sufficient
Reliability?
No Yes
None Pager? External Alarm? 3rd Party?
Other?
No Yes
22. Physical assessment topics
1. Control room continuously
manned
Cover for meal and toilet
breaks
2. Operator always at
console
Issuing permits, secondary
consoles
3. Operators distracted Phone calls, visitors, alarms
4. Obtaining information Process data, drawings,
documents
5. Calling for assistance Help with diagnosis
6. Number of people
required
Where are they, what will
they be doing
7. Communications during
response
Radios, phones, backup
8. Additional activities Raising alarm, roll call
23. Ladder Assessments
Assessment of individual and organisation
factors
Set of questions encourage assessment team to
consider the key issues
âLaddersâ provided to assess adequacy
Each rung is a description of system attributes
Start at the bottom, how high do you get?
Minimum, acceptable levels are defined for each
ladder.

27. Other considerations
Routine workload
More critical for plant with reliable trip systems that
are easy to start and stop
List tasks and approximate duration
Should be significantly less than 100% loaded
Plant disturbances
Frequency
Number of people involved and duration
How do they impact on the routines?
28. Conclusions
Two methods to assist assessments of staffing
arrangements
Give some objectivity
Proven to provide a useful framework for
assessments
Particularly useful when considering changes
Rarely a pure numbers game
Alternatives to employing more people.
29. Common themes
Over reliance on informal training
Inadequate refresher training
Too many distractions in control rooms
Nuisance alarms
Visitors, contractors, day staff
No control on shift swaps, overtime, breaks etc.
Very passive approach to stress and fatigue
Poor management of the safety implications of
organisational change (including staffing levels)
Failure to consider human factors when
automating.
30. Problems with change
Financially driven
âTrendyâ organisations
Full impacts of change not understood
No monitoring of the impacts of change
Lack of objectivity in planning
Inadequate staff to deal with foreseeable events
Loss of practical and technical competence
Assumption that change will be successful
Lack of buy-in.
