INAIL OT23 2027 – New Opportunities to Reduce Insurance Premiums: Smoke Control Systems and Emergency Response Training Among the Key Updates in the New Model

August 4, 2026

INAIL has published the new OT23 Model for 2027, the tool that enables companies to obtain a reduction in their average insurance premium rate by implementing workplace health and safety improvement measures.

For activities carried out during 2026, the new model introduces several significant updates, particularly affecting the fields of fire safety and emergency management.

What’s New in the 2027 OT23 Model?

– Smoke Control and Heat Exhaust Systems

Among the newly rewarded measures is the installation of smoke control and heat exhaust systems in the event of a fire. These systems play a crucial role in improving evacuation conditions, facilitating firefighters’ operations, and limiting the impact of a fire on people and property.

– Enhanced Emergency Response Training

The new model also places greater emphasis on training employees as emergency response personnel, first aid responders, and cardiopulmonary resuscitation (CPR) providers. This approach aims to strengthen the safety culture within organizations and ensure greater preparedness in managing critical situations.

Why Should Companies Take Action Now?

The measures that qualify for OT23 benefits must be planned and implemented during 2026. For this reason, companies should begin evaluating:

  • the current status of their health and safety measures;
  • the improvement actions that can be implemented;
  • the documentation required to support the future application for the INAIL premium reduction.

An Investment That Creates Long-Term Value

The measures introduced by the new OT23 model should not be viewed solely as a way to obtain a reduction in insurance premiums. Installing smoke control systems, improving employees’ emergency preparedness, and strengthening emergency management procedures significantly enhance the protection of people, safeguard business assets, and increase an organization’s overall resilience. The two new measures introduced in the 2027 OT23 Model clearly move in this direction: they represent an investment that creates lasting value.
