What worked well: Preparation
• Technical preparation of critical projects:
•
•
•
•
Procedures incl. Safety measures
Conformity of mechanical equipment
Pre-LS1 Training on the job
ALARA approach for radiation protection
• LS1-specific training:
• LS1 sensibilisation on SIR
• 2-level RP training (e-learning for most LS1 participants)
• Technical solutions:
• IMPACT for activity planning
• TREC for equipment from radiation areas
• Automatisation of operational dosimetry

What worked well: Flexibility
• Safe solutions for unforeseen issues
• Relax hard-hat and Self Rescue Mask rules at fixed
workstations
• Introduce bump-caps under clearly defined conditions
• Ad-Hoc decisions with Safety Relevance
• Ventilation speed for geometers
• Work-arounds to failing LHC lifts (means of evacuation)
• What to do when a “safe area” is temporarily
unavailable ?
• Co-activities during equipment check-out

4
What worked well: Management
• Project Coordination
• 16 persons fully employed in coordination activities (of
which 6 Safety coordinators)
• Fire Safety: control over max. personnel in tunnel sector
• Safety officer cooperation
• Sharing of tasks
• Similar solutions for similar problems
• Communication with Project Management
• Presence of Safety Officers in restricted and public
committees
• All Project / Sub-Project Managers had an open door

What could be improved: Preparation
• Observation:
• Most LS1 accidents were suffered on the surface,
where no specific prevention measures were taken
• Recommendation:
• Preparation of procedures with accident prevention
measures for all sub-projects
• A model can be made available from the SMACC
project

6
What could be improved: Training
• Observation:
• The major positive reforms (LS1, RP) were
implemented in the last minute (February 2013)
• Recommendation:
• Freeze Safety Training several months before LS to
allow all persons to conform
• To make it happen:
• Assess Safety training needs for the project
• Based on early risk assessment

What could be improved: Training (2)
• Observation:
• Language barrier in Electrical Safety training for
electricians (PJAS / COAS)
• Recommendations:
• Develop CERN-specific electrical safety training also for
electricians
• Accept foreign safety training status of electricians

What could be improved (3) ?
• Observation:
• Last-minute Safety measures, after budgets have been allocated.
(Special vacuum cleaners)
• Recommendation:
• Freeze all Safety measures well before LS
• Allows consideration in budget allocation
• And inclusion in contractual documents
• Observation:
• Increase of the number of co-activities towards the end of LS1:
Last minute jobs
• Recommendation
• Properly plan all interventions
• Allow co-activity / last minute jobs only under well-justified
circumstances

Safety Summary
what
I - keep
II - improve
III – change
List the different aspects in the
management of the work carried
out during the LS1
Define what should be kept and
was an added value during the
LS1
Define what you propose to
improve in order to better manage
the LS2
Define what was a bottleneck to
carry out the work during the LS1
and needs to be changed for LS2
Safety Training
•
•
•
•
LS specific safety
training
Training targeted to
risk profile of person
•
Freeze access and
training req’s early
Assess training
needs
Safety Rules
Freeze well before LS
Procedures & Accident
prevention
Extend to all subprojects
ALARA approach
Worked well
Take preparatory work
into account
Better discipline
(radioactive) waste
& material
Last minute jobs
Storage space
(in progress)
Need to be identified
and (temporarily)
classified (in progress)
Radioactive work
areas
Coordination
•
electrical training
for electricians
Safety training
centre
Keep at similar level
Only with serious
justification
