Quality and certification


For Safety, Quality and the Environment, INVEHO undertakes to deploy a single strategy across each of its sites, in line with the Ermewa Group’s commitments, to ensure that all stakeholders are safe, deliver customer satisfaction, and reduce our carbon footprint.


Bridge crane operator accreditation

Trainings delivered are based on CNAM recommendation R484. The goal is to provide the theoretical and practical knowledge required to operate bridge cranes, learn safe slinging rules, and deliver the operating authorization > the goal is the carriage of heavy loads in the workshop.


Forklift truck operator (R489 category 3) and heavy plant machinery operator (R482 category F) accreditations  

These training courses are based on recommendation R489 category 3 for forklifts with a design capacity of < 6,000kg, and recommendation R482 category F for worksite machinery.

The goal of these trainings is to prevent risks and optimise safety on plants. It also allows to meet the training obligation  with the aim of delivering an operating authorization > handling of wheelsets in the facility, loading and unloading of heavy equipment are the target.


In the German workshops, the complete knowledge management is administrated with the help of the digital personal file. All qualifications and training courses are kept and monitored in it. This enables us to ensure that each of our employees is always fully qualified for his or her job and is up to date with the latest technology and general regulations. For over ten years, we have thus ensured that our work is based on the latest technical expertise.

As part of a continuous health and safety improvement process on plants, in September 2020 all french workshops appointed representatives whish aim is to supply any relevant information to management in order to prevent from accidents.

34 volunteer representatives, mostly in the workshops, agreed to carry out this role, which involves:

  • Locating and being informed on operating lacks and/or beginning of accidents by colleagues.
  • Informing and advising colleagues faced to hazards in order to suggest solutions to them.

These volunteers also completed a first aid training of work rescuer in order to provide first aid to any victims of accidents or anyone who gets sick at work, as well as to be actively involved in prevention inside the workshops.


Handlings safety has been improved by installing additional sound and visual warning signals.
Flashing lights have been installed at strategic locations where lines cross to add a visual warning to the existing alarm system.
In addition, the handlings team has been provided with a Bluetooth system, enabling drivers to concentrate on their environments and, in that respect, limit the risk of accidents.


At INVEHO UFF, the first 5S method was undertaken at the DLD1 wheelset facility (dismantling, washing, offsetting, sector 1).

Process stages:

> Stage 1 SEIRI: Sort and remove useless materials. 

> Stage 2 SEITON: Tidy

> Stage 3 SEISO: Clean

> Stage 4 SEIKETSU: Standardise

> Stage 5 SHITSUKE: Follow up.

The aims are:

– Improve working conditions.

– Reduce the risk of falls accidents.

– Reduce the risk of work-related illnesses.

– Increase productivity.

Employee safety is our priority! 

Other 5S methods are planned in France and Germany!


We regularly undertake exercises with the Fire and Rescue Services. Several difficulties/problems are simulated during these exercises. The firefighters appraise these various exercises as they enable them to understand and anticipate our issues. In that respect if one day, they are called out to attend a similar incident on our site, they are not coming on an unknow location. Furthermore, our staff is trained to use fire extinguishers (team for first intervention).


The Internal Operational Plan is an operational decision-making tool and can be used internally or by external emergency services when an incident occurs. It details the organizational rules, the resources in place and available on an industrial site in order to minimize the consequences of a potential major incident for people, the environment and property. The plan therefore focuses on managing “significant and representative” accidents that may occur, such as fires, explosions, liquid product spills, atmospheric dispersion of toxic substances etc.


In the German workshops there is also a defined scenario for rescuing people from tank wagons; this has been worked out with the fire brigade and rescue services. Regular drills ensure that all employees working around tank wagons are familiar with these procedures and can safely apply these measures at any time in the event of an emergency.


The software has been developed by INRS (National Research and Safety Institute) and made available to business in order to list and assess the risks linked to chemical products.

SEIRICH meets our needs because it has the following features:

  • Easy chemical products data entry: Indicate hazards and quantities used of our products.
  • Multi-zone management: Split our company into several zones.
  • Residual risk: Accurate risk assessment of a workplace task.
  • Action plan: Create and manage our action and prevention plan.
  • Data exploration: Analyse our chemicals stocktaking during many years.
  • Simulation: Measure the impact of future actions.
  • Personal Protective Equipment: The effectiveness of different types of PPE is taken into consideration when calculating risk.
  • Analysis of labels and Safety Data Sheets: SEIRICH can extract hazard statements from these documents.
  • Printing: Print out our documents: workplace instructions, labels etc.


In order to protect our employees as best as possible even when working alone, a personal emergency signal system has been introduced. The devices are carried by the employees so that they can make an emergency call at any time should something happen to them. The devices also set off an alarm on their own if the employee does not move for a certain period of time and it is suspected that something may have happened. With this system, we have ensured that personal injuries can be communicated as quickly as possible and help can be initiated. The safety of our employees is our top priority!



EVA gives IT equipment a new lease of life and offers sustainable employment to people with disabilities.
Located in La Fare-les-Oliviers, EVA collects IT equipment in the companies in order to give it a second life.
The company also offers IT maintenance and data erasure services.

A new waste process organization has been implemented in INVEHO UFF site in order to reduce costs, recycle waste.
In that respect, we have selected partners with their own specialities: hazardous wastes, pallet recycling, non-hazardous wastes, pumping specialists.

Other waste optimisation and recycling projects are planned in France and Germany!


More than half of the electricity required by the German sites is produced on site. Through energy-efficient CHP and a large photovoltaic system at the INVEHO FWN site, we generate electricity and heat decentrally and efficiently, making a significant contribution to the environment.


ISO 14001 assessment: the first step towards having an Environmental Management System.

The INVEHO business unit is committed in an environmental initiative for several years. We carry out environmental assessments across all the sites every three years.

These ISO 14001 assessments help us to identify our level of compliance with the standard, analyse our environmental situation, evaluate our organisation’s strengths and weaknesses, and identify the best strategy for obtaining site certification in the very near future.

INVEHO UFF is committed in an ISO 14001 certification process, as a pilot, with the aim to obtain certification in 2022.

All of our German workshops already hold this certification ISO 14001.

Some great environmental projects for 2021 are under study in order to go on continuous improvement: waste disposal unit retention system, purchase of new watertight skips, installation of lights, new waste disposal unit with oil separator.
