A mechanical workshop is an environment where worker safety and health are top priorities. One of the major challenges is the management of exhaust gases produced by vehicles, which contain harmful substances. But which regulations govern the extraction of these elements? And how can these requirements be translated into practical and effective solutions?
In this article, we explore the key aspects of the regulations concerning fume and gas extraction, providing a practical guide to ensuring a safe and compliant working environment.
Before delving into regulatory details, it is crucial to understand the importance of an efficient exhaust gas extraction system. Vehicle exhaust gases contain carbon monoxide, nitrogen oxides, unburned hydrocarbons and particulate matter, all of which are highly harmful to human health. Prolonged exposure to these substances can cause respiratory problems, headaches and, in the long term, more serious illnesses, potentially even leading to death.
An adequate extraction system not only protects employee health, but also helps keep the workshop clean, improving overall air quality and workplace comfort.
In Italy, workplace health and safety are primarily regulated by Legislative Decree No. 81 of 9 April 2008 (known as the Consolidated Act on Health and Safety at Work). This decree establishes a series of obligations for employers, including the requirement to assess all risks present in the workplace and to adopt the necessary preventive and protective measures .
Legislative Decree 81/08 places particular emphasis on air quality in working environments. Although it does not specify exact limits for each individual pollutant (often referring instead to technical standards or specific guidelines), it imposes the obligation to ensure adequate ventilation and air renewal.
In environments such as mechanical workshops, where pollutants are generated, this translates into the need for systems capable of diluting and removing harmful agents.
With regard to regulations specifically related to vehicle exhaust gases, although there is no single article detailing requirements specifically for the automotive sector, the application of the general principles of Legislative Decree 81/08 implies that:
they must be subject to regular maintenance to ensure correct operation
Understanding regulations is the first step, but how can they be translated into concrete actions?
1. Risk Assessment (DVR): The Risk Assessment Document is the starting point. A qualified professional must analyse the workshop, identify exhaust gas emission sources and assess the risks to workers’ health. The most suitable solutions will then derive from this analysis.
| System type | Application |
| Fixed system | Ideal for exhausting gases in workshops with irregular layouts, where work areas are unevenly distributed, often small or medium-sized |
| Sliding system | Ideal for exhausting gases in workshops with regular layouts, often larger facilities |
| Underfloor system | Ideal for workshops that need to keep overhead spaces clear or have aesthetic requirements |
| Mobile system | Ideal for small workshops with less frequent and more isolated applications |
3. Ensuring adequate air renewal: In addition to localised extraction, it is essential to ensure sufficient general air renewal within the workshop, including through forced ventilation systems, to dilute residual pollutants and maintain a comfortable environment.
4. Worker training and information: Employees must be trained on the importance of correctly using extraction systems and on workplace safety procedures.
Relying on experienced suppliers specialising in exhaust gas extraction is essential. Companies such as WORKY offer solutions specifically designed for automotive workshops, engineered to comply with regulations while ensuring maximum efficiency and safety. From individual mobile units to centralised systems, the choice depends on many factors — and this is where experience plays a fundamental role.
Ensuring a healthy and regulation-compliant working environment is not only a legal obligation for a mechanical workshop, but also an investment in employee health and in maintaining a productive business.
