Lone worker

Don’t work alone in a laboratory:

If you are exposed to danger, you need to be able to get help in an emergency !

If possible, always work in pairs !


Definition of an isolated worker:

An isolated worker is one who cannot be rescued immediately after an accident or in a critical situation (sudden illness). This is the case, for example, when a person is working without visual contact with others, or out of earshot.

The information below applies to the Lausanne campus only. If you work on an associated campus, please contact your campus security service.


What do I have to do?

If you are forced to work alone, outside working hours (7pm to 7am and on weekends and public holidays), you must:

  • Inform your unit manager.
  • Contact the OHS-PR for an assessment of the situation.

If working alone is authorized, and depending on your geographical location, you can either wear a DATI or ‘Man-down’ device, or report to the EPFL’s Centrale d’Alarme et d’Engagement (CAE) using the procedure below.

If work alone is accepted, you must answer the following questions:

  1. Is there a specific emergency procedure?
  2. Are you aware of the danger of working alone?
  3. Are you aware of the necessary safety measures (behavioral, PPE)?
  4. Have you received work instructions?
  5. Are you familiar with the “Call to CAE” procedure?
  6. Do you know how to use a DATI?

Procedure for calling CAE:

  1. Contact the CAE on 021 693 40 00 (internal: 34000) BEFORE starting work and indicate:
    • Nom et prénom
    • Local number
    • Landline telephone number (if available)
    • Cell phone number
    • Expected working time in the area
  2. Every hour, CAE will make a call to the numbers given. First on the landline, then on your cell phone. You must answer these calls.
  3. When you have finished your work and are leaving the premises, call CAE on telephone number 021 693 40 00 (internal: 34000)

If there is no response to two attempts at the two numbers given, CAE will alert the emergency response group for the Lausanne site.

WARNING: If two unjustified interventions are carried out on the same premises or by the same user, the costs will be billed back to the unit manager.
