About INEXIS
INEXIS Sàrl is a specialized engineering office (bureau d'ingénieurs conseils) based in Paudex in the canton of Vaud, offering a comprehensive range of services in the fields of safety and fire protection. Its services include safety and fire protection concepts, risk analyses according to OPAM, industrial and process risks (HAZOP, FMEA/AMDEC, FTA, HSE audits), chemical risks (ATEX, GHS, ADR, TRCI, CARBURA), fire protection according to AEAI guidelines and NFPA, technical project acceptance as well as occupational safety. For complex studies, the office develops its own software programs, including OPAM tools for gas pipelines, roads and railway lines, the coupling of the EFFECT (TNO) software with GIS data, as well as tools for fire modelling and smoke extraction dimensioning (FDS). The service portfolio is aimed at industrial companies such as chemicals, petrochemicals, cement, pharmaceuticals, food and logistics warehouses, at the construction sector and the public sector, at operators of gas and oil pipelines and at the transport of dangerous goods by road and rail. The office emphasizes its independence from plant installers and equipment suppliers.

Tools and Methods
Risk studies according to OPAM
Studies for risk analysis, among others for gas pipelines, roads and railway lines, including scenarios such as pool fire, BLEVE, explosion, toxic cloud, VCE and boil-over.
EFFECT (TNO)
Modelling software for calculating effect distances in accident scenarios such as pool fire, BLEVE and VCE.
FDS (NIST)
Fire modelling, among other things for the dimensioning of smoke extraction systems.
GIS (SIG)
Evaluation of cadastre data and population density for calculating the severity of accidents.
HAZOP, AMDEC/FMEA, FTA
Methods for analysing industrial process risks as well as HSE audits and SMS/SGS.
ATEX, GHS, ADR
Assessment of chemical and explosion risks as well as dangerous goods.
Fire protection according to AEAI / NFPA
Fire protection concepts, fire audits and inspections according to AEAI guidelines and NFPA.
