Knowledge base
Practical guides to occupational risk assessment and workplace accidents, occupational hygiene and chemicals, technical safety, training and EHS culture, and lone worker protection.
Every article in the VIMS knowledge base comes from real deployments at Varilo customers and describes the process from the point of view of the person who runs it: the EHS specialist, the quality manager, the maintenance lead, or the board member accountable for compliance. Nothing here is written purely for search engines — each guide ends with the decisions you need to make and links to the modules where the process is actually carried out.
Guides are grouped into five areas. Pick an area to see only the related articles.
Most plants record events correctly and analyse them reasonably well. The problem comes later: the analysis ends in a report, the action ends in an email, and the risk assessment stays exactly as it was before the event.

Read the guideThe question “how often should we update the risk assessment” is almost always the wrong one. The right question is: what had to change for the existing assessment to stop describing reality.

Read the guideSafety data sheets are rarely the problem in themselves. The problem is that nobody knows how many substances are really on site, who ordered them, or whether the sheet in the binder matches the version of the product standing in the store.

Read the guideNobody abandons spreadsheets because they look bad. They abandon them because, two days before an audit, three people are reconstructing which version of the file is the right one.

An auditor is not looking for a thick binder. They are looking for evidence that what the procedures say actually happens on the shop floor — and that the organisation learns when something goes wrong.

Few people fill in a form. Almost everyone will talk at the machine — if they know nobody is looking for someone to blame and that the problem they raise will actually be fixed.
