Replace an HSE manager
Departure, absence or vacant post: ensure continuity in managing the department, regulatory deadlines and the relationship with the authorities.
HSE transition management
Interim HSE manager:
take over, ensure continuity.
An interim HSE manager takes on, for a limited period, responsibility for a health, safety and environment function: replacement, reinforcement or transformation. Sergio DOSSOU works this way on ICPE and SEVESO sites in France; IFECARM GROUP also supports organisations in Africa and Europe.
When to call one
A specific need,
a limited duration.
An interim assignment answers an identified situation. The most common cases:
Reinforce the team at critical times
Certification audit, compliance programme, ICPE regulatory file, remediation: bring directly operational expertise to the existing team.
Transform the management system
Audit the current system, build a master plan and a roadmap, move a quality system towards an integrated QHSE system (ISO 14001, ISO 45001).
Take over a high-risk site
ICPE and SEVESO sites: help reduce accident rates over the long term, structure HSE governance and strengthen the safety culture across the whole site.

What is an interim HSE manager?
An experienced professional who takes operational responsibility for a health, safety and environment function for a defined period. They lead the team, manage regulatory obligations and move priority projects forward, then hand over.

Sergio DOSSOU works in both modes, consulting being carried by IFECARM GROUP.
