2. What’s lone working ? Existing Regulations Why do we need a rule? Choices Principles of the rule When do we need at least 2 persons? Flowchart F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

3. Definition : Lone working : work is considered to be in isolation when a person is working out of sight or earshot of other people. (Adaptated from definition of CNAMTS (Caisse Nationale de l’Assurance Maladie des Travailleurs Salariés). F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

4. RegulatoryContext F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

5. Why do weneed a rule? • Definitions and requirements are different in both Host States, but the goal is the same, ensure safety of lone workers (lone working can make rescuing a person more difficult in case of accident) • Reminder • the need to identify all types of lone working • the need to assess risks • Refresh and remove ambiguities of the current Safety Code A6 and Safety Note NS8 published in 1982 • Adapt the rule with the use of new devices as “Lone Worker Mandown Device” (TETRA/DATI) F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

6. Main choices • Definition adapted from CNAMTS (Caisse Nationale de l’Assurance Maladie des Travailleurs Salariés). Lone working not necessarily linked to hazardous works. • Risk assessment for each type of lone working. • Possibility in some specific cases to use “Lone Worker Mandown Device” (TETRA/DATI) ( warning : sometimes not suitable ) • List of jobs requiring special supervision, adaptation of French and Swiss regulations • Allow lone working during night and closure periods. F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

7. Principle (general) • Give priority to not working alone • In all cases, assess the risks and take into account: • Location and type of work ; • Capacity and fitness of the lone worker; • Probability of occurrence of the identified risk; • Gravity level of possible accident including potential injuries • Possibility to alert and of rescue • Time to take into account the victim F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

8. Principle (in case of accident) • Possibility to move away from the source of danger and to raise the alarm, • and victim can await rescue : • appropriate means of communication • No possibility to move away from the source of danger or to raise the alarm and • victim can await rescue : • appropriate technical means or organisational procedures to alert • the CERN Fire and Rescue Service • Victimshallbeimmediatelyrescued : at least twopersons • earshot of or in visual contact with a third party, or • continuous surveillance by a third party F.

Continuous surveillance by a third party • Work in confined spaces; • Work on installations or in service rooms containing live electrical equipment; • use of explosives during building and public works or agricultural work; • Work in chimneys or large heating installations; • Work in hyperbaric or pressurised locations or involving compressed air; • Work in, or on the banks of, rivers, streams, pools or other bodies of water where there is a risk of someone falling into the water; • Work where the risk assessment shows the need for continuous surveillance by a third party. Safety guideline will explain, lone working is authorised where there is no possibility to be in contact with electrical parts or of short circuit. • Restart of PC • Reset of a breaker on 400 V electrical cupboard installation with low current of short circuit (Ik3<3kA) • Rearming air conditioning • Correction of the fault on UPS • Correction of the fault on 48V • … F. Angerand HSE/SEE – EXSO EP HSE - 18th November 2016

10.
