If chemicals are used in your company, even just for cleaning or painting, the chemical risk assessment is not a formality. It is a concrete responsibility that has a real impact on the health of those who work in those environments every day. We are not just talking about industrial plants full of toxic substances: even a small laboratory, workshop or cleaning business can hide risky exposures.
Yet it often happens that this assessment is seen as a “mandatory task to get out of the way”. But its real value lies elsewhere: in preventing health problems, even serious ones, and in ensuring a safer and more aware working environment.
What chemical risk assessment really is
Unlike other risks, the chemical one is neither seen nor heard. There is no spark, no collapse, no machine breaking down. Yet it can be even more dangerous, because it acts silently, day after day. The chemical risk assessment serves precisely to identify and manage these invisible exposures.
The process consists of understanding whether and to what extent the substances present in the company can cause harm to health or endanger safety. And it is not just about products declared toxic: even a glue, a paint or a detergent can cause problems if used badly or for too long. So yes, it is an assessment to be done with care, with method and, above all, with a certain dose of realism.
When it becomes mandatory
Many wonder whether there are thresholds or cases in which this analysis can be “skipped”. In reality, the law is quite clear: if there is even a single hazardous chemical in your workplace (identifiable through its label, safety data sheet or CLP classification), then the assessment is necessary.
It does not matter if you use it in minimal quantities or only keep it in storage. As soon as there is a possibility of exposure for anyone, you must assess the risks. Moreover, this assessment must be updated whenever something changes: if you introduce a new product, if you change a process, if you increase shifts or if the duration of exposure changes.
Who is responsible for it
The responsibility lies entirely with the employer, who must guarantee a safe and healthy environment. This does not mean they must handle it alone: they can (and often must) rely on the RSPP, the company doctor or consultants with specific experience. However, it is they who must decide, take action and check that things are really done.
And no, it is not enough to download software and run an automatic calculation. Tools help, but only if accompanied by on-the-ground observation, dialogue with workers and a pinch of common sense. Because an assessment done only on paper risks protecting no one.
How the assessment works: a matter of method
Assessing a chemical risk is not a matter of numbers and formulas, but of observing what really happens in the company. You start with an inventory of the substances present: not only those purchased, but also those formed during work (think of welding fumes or sanding dust). From there, you consult the safety data sheets, which contain key information on hazards and precautionary measures.
The next step is to understand who comes into contact with those substances, how and for how long. It is also necessary to assess ventilation, the equipment used and the real level of exposure. At this point the data collected are cross-checked and the level of risk is estimated. The result is not just a score, but a set of actions to implement to prevent or reduce the danger.
Methods exist, but must be chosen wisely
There are different systems for making the estimate, from the simplest to the most technical. One of the best known in Italy is MoVaRisCh, but there are others too: INRS, COSHH Essentials, or proprietary models developed in-house. The important thing is to choose the method best suited to the company context, without being guided only by haste or ease of use.
Some simplified methods are useful in micro-enterprises or when handling only a few substances. Others, more detailed, are needed in complex environments where exposures are multiple or prolonged. But in any case, no method works if the starting data are not realistic.
The most common mistakes to avoid
It is common to see assessments done in a hurry, perhaps copied from another DVR. This is a mistake that can be costly. Underestimating seemingly “harmless” products can also create risk situations. A substance may not be dangerous if used for a few seconds, but become so if it builds up in the air or is used for hours.
Also beware of not updating the assessment when changing product or moving to a new procedure. A change of supplier or a different method of use is enough to alter the entire exposure. Finally, another widespread mistake is not involving workers: those who use these products every day often know problems and critical issues that do not emerge from documents.
Some practical tips
If you want to tackle chemical risk assessment seriously but sustainably, here are some smart moves you can put into practice right away:
- collect all safety data sheets in an easily accessible folder
- check the labels and CLP classifications of every product
- directly observe how substances are used during activities
- interview those who work in contact with these products: they often have information that documents do not report
- choose a method consistent with your type of company and the number of substances handled
- check that personal protective equipment is adequate and used correctly
- update the assessment whenever a product, a task or a procedure changes
- document everything in the DVR, clearly and accessibly
The question of “irrelevant” risk
Some companies believe they are not at risk because the substances used “are minimal” or “are only used once in a while”. But the concept of irrelevant risk is not based on feelings or impressions. It must be demonstrated, justified and substantiated objectively.
In certain cases it is legitimate to use a simplified method, but you cannot simply write it in the DVR and hope that is enough. Irrelevant risk is a possible condition, but it must emerge from a genuine analysis. And even in those cases, training, information and minimum safety measures remain mandatory.
How much training matters
A worker who can recognise a hazard symbol, who knows how to use PPE correctly and who understands why a procedure exists is already far better protected than someone who works “by instinct”. Training must not be a course to sign and forget, but an opportunity to make people more aware and autonomous.
Explaining well how to read a safety data sheet, how to use a respirator or how to react to a spill makes an enormous difference. Also because risks often come not only from what you do, but from what you ignore.
Towards a more sustainable approach
More and more companies are taking environmental issues seriously in the field of safety too. Reducing the use of hazardous substances or finding greener alternatives is good not only for workers, but also for the company’s reputation. It is not easy, of course, but it is worth exploring the options. And when a harmful product can be replaced with a safer one, the assessment becomes a tool for real improvement, not just an obligation to be filed away.
Chemical safety is a concrete responsibility
The chemical risk assessment is not a bureaucratic nuisance to be delegated or postponed. It is a concrete step to protect the health of those who work every day with products that, if badly managed, can cause serious harm. Doing it well means knowing the substances, observing real conditions, involving those who work, choosing the right methods and not forgetting to update.
You do not have to be a chemist or engineer to understand the importance of this process. You only need willingness, attention and a little method. And, above all, you need the idea that safety is not a cost: it is a concrete, daily responsibility.
