Serious Games for Chemical Risk: Learning Pictograms and Procedures by Playing

Chemical risk is a recognition problem

Much of chemical safety depends on daily micro-decisions: reading a label, recognising a pictogram, consulting the safety data sheet, choosing the right PPE, handling a spill. This knowledge fades quickly if learned only in a lecture. The serious game — a game designed with an explicit learning objective — lets people train this recognition in a repeated, engaging way.

The regulatory framework

In Italy protection from chemical agents is governed by Title IX of Legislative Decree 81/08 (Chapter I, "Protection from chemical agents", Articles 221 onwards), which requires risk assessment and prevention measures. Classification and labelling follow the CLP Regulation (EC) No 1272/2008, while the REACH Regulation governs substance registration; safety data sheets (SDS) communicate hazards along the supply chain. An effective serious game is built on this real content, not generic notions.

What a chemical-risk serious game can train

Recognising CLP pictograms

The nine hazard pictograms (red diamond on white) are an alphabet that must become automatic. A rapid pictogram-hazard-behaviour matching mini-game creates lasting associations, complementing what is learned about safety signage.

Reading safety data sheets

Simulations where the player must find the right information in the 16 SDS sections — first-aid measures, storage, PPE — train a practical skill often neglected.

Managing critical scenarios

Spills, incompatible mixtures, insufficient ventilation: multiple-choice scenarios with consequences train judgement safely, where the mistake is virtual.

Why the game works here

Evidence on gamification and serious games in safety training points to greater engagement, participation and knowledge retention, thanks to mechanics like points, levels and challenges. As explained in our guide to gamification in safety training, the added value is motivated repetition: people come back to play, and each repetition consolidates memory.

Fitting it into the path

The serious game does not replace chemical-risk assessment or the specific training required by Title IX: it precedes it to build familiarity, or follows it to consolidate. The debrief links game choices to real company procedures.

In short

For chemical risk, where so much depends on fast recognition and procedures, the serious game is a natural tool: it makes pictograms, sheets and behaviours memorable, provided it is built on real regulatory content and closed by a good debrief.
