Safety correspondents (COSEC) are the first safety contact for each research unit.

Roles and responsabilities:

Professors and heads of unit are by default the security correspondents (COSEC) for their unit.

They may delegate this task to an experienced employee.

The role of COSEC is to:

  1. Transmit the information sent by the DSE to the unit staff.
  2. Inform the OHS Service of any safety-related changes in the unit, such as new hazards, modifications to facilities, new activities and scale-ups of experiments.
  3. Participate in the safety audits.
  4. If the COSEC function has been delegated to her/him, inform the professor or direct supervisor of any security-related problems in her/his unit (dangerous behaviour, refusal to wear safety equipment, hazardous handling of reagents or waste, etc.).
  5. Inform the DSE, or ensure that the DSE is informed, of security-related incidents or accidents via the dedicated tool.
  6. Where applicable, create and update “door safety sheets” on an annual basis.
  7. Where applicable, periodically check and update first aid equipment (e.g. eye rinses, first aid kits).

The COSEC must be a person who has:

  1. The training and experience required to perform the security duties assigned to him or her.
  2. Knowledge of and expertise in handling unit-specific hazards.
  3. Insight into the unit’s activities and associated risks.
  4. If the COSEC function has been delegated to him or her, he or she must have the authority to impose the OHS rules in relation to the unit’s activities.
