The Devea company and its expertise

Jean-Marc Evanno, helped by over 20 years of experience in sensitive industrial sectors, has decided to offer his expertise and knowledge in hygiene to companies round the world


  • General hygiene procedures
  • Clean room and confined spaces hygiene
  • Airborne disinfection procedures
  • Animal facilities
  • Laboratories
  • Public Space hygiene


  • Pharmaceutical industry
  • Food industry
  • Cosmetics industry
  • Animal Facilities
  • Laboratories
  • Public Areas


The audit take place on-site, according to the following typical procedure:

  • Meeting with Management Department (industrial or General) who must be involved
  • Site visit
  • Analysis of procedures in place, how they are applied daily and of their results
  • Meeting with manufacturing process participants, evaluation of their involvement
  • Identification of potential deviation from procedures, cause and effects analysis
  • Writing of report, which will be presented to Management Department

If the Management authorities agree with the report’s findings, the report and its recommendations will be communicated to the staff involved.

…to improve on hygiene procedures

From the audit report findings, suggestions to improve on hygiene procedures are proposed.

This phase implies all staff involved in the fabrication/manufacturing process. It leads to recommendations to reach improvements in site procedures regarding hygiene.

  • New presentation to Management representatives and Quality Department.

If the recommendations are agreed, the next phase is then to help in the writing of revised or new procedures, which have to be strict, to the point and accessible.

Staff training

Hygiene is first and foremost a frame of mind.

Any procedure, however brilliantly written, will not be efficient if it not accompanied by a practical training session on-site so that each member of staff understands what is at stake, and the consequences of his/her own actions.

The training course will be adapted to the knowledge and implication levels of the persons involved in the manufacturing process.

Modules will be put in place, from generics to specific subjects, and always with a view of offering applied and concrete suggestions:

  • Basic and general hygiene for Public areas and Industrial facilities:

    • What is cleaning, which products should be used, which tools are good performers, what results can be expected. Constraints and pitfalls.
    • Same procedure for disinfection.
    • Risks of poor handling methods, risks of chemicals used to the operator, and to the company.
  • Clean room hygiene

    The particular environment of controlled clean rooms implies new constraints, stricter and more specific procedures. The increased risks associated with the « non-conformity» have serious enough consequences to adapt the training and levels of information given to the employees concerned.

    • Presentation of European microbial norms, of products available in sterile form, of their usage and of the adapted tools.
  • Airborne disinfection

    This is a well-known method (depending on the activity sector), but is often poorly put in practice and/or badly understood. It is therefore necessary to promote this technology with the relevant constraints and advantages of the various techniques available on the market.

    • Presentation of the norm and of its evaluation parameters.
