LEGIONELLA AND ITALIAN DECREE 81/2008: ART. 271 BIOLOGICAL RISK
Article 271 of the Italian Legislative Decree 81/2008 classifies Legionella pneumophila as a Group 2 biological agent and requires the Employer to assess biological risk in every activity with potential exposure to aerosolised water: plumbing systems, evaporative cooling towers, humidifiers, decorative fountains, hot tubs.
What art. 271 sets out in detail
Art. 271, Title X (Exposure to Biological Agents) of the Italian Consolidated H&S Act enumerates the five core duties of the Employer.
- Identify the presence of biological agents (Legionella spp.) and assess the risks to workers' health (paragraph 1)
- Consider information on occupational diseases and possible allergic or toxic effects (paragraph 1)
- Adopt technical, organisational and procedural measures suitable to prevent or reduce exposure (paragraph 2)
- Update the risk assessment in case of significant modifications or new epidemiological evidence (paragraph 3)
- Retain assessment data and keep it available for the enforcement authority (paragraph 5)
What the Employer must do in practice
From the principles of art. 271 to operational actions: the ten minimum tasks for compliance.
- Duty 1
Biological risk assessment
Identify all plumbing points potentially colonised by Legionella (boilers, storage tanks, outlets, cooling towers).
- Duty 2
Drafting of the Legionella DVR
Add to the general DVR a specific section on biological risk from Legionella, signed by the Employer and countersigned by RSPP and Occupational Physician.
- Duty 3
Appointment of the RSPP
Designate the Prevention & Protection Service Manager with competencies on waterborne biological risk.
- Duty 4
Appointment of the Occupational Physician
For activities requiring mandatory health surveillance, appoint the Physician who evaluates exposed workers.
- Duty 5
Technical prevention measures
Temperature control (hot water >55°C, cold water <20°C), elimination of dead legs, periodic maintenance of storage tanks and outlets.
- Duty 6
Organisational measures
Operating procedures, maintenance registers, sampling plan, management of non-conformities.
- Duty 7
Training and information
Train exposed workers (maintenance, cleaning) and inform all staff about risks and measures (arts. 36-37).
- Duty 8
Health surveillance
Activate health surveillance under art. 279 for exposed workers, with periodic visits and targeted screening.
- Duty 9
Emergency measures
Procedures for positivity events, thermal shock, hyperchlorination, communication with health authorities.
- Duty 10
Documentation retention
Keep DVR, lab reports, maintenance logs available for ASL and Labour Inspectorate inspections.
RSPP and Legionella risk assessment
The RSPP is the Employer's technical referent: coordinates the assessment and proposes the measures, but legal responsibility remains with the Employer.
- Coordinate the Legionella risk assessment (art. 33 of Legislative Decree 81/2008)
- Identify risk factors specific to the water system
- Propose worker training and information programmes
- Attend the periodic meeting (art. 35) with Employer, Occupational Physician and Workers' Safety Representative
- Contribute to the sampling plan and action thresholds
- Update the risk assessment in case of plant modifications or sentinel events
Art. 279 — Prevention and monitoring
For workers actually exposed, Legislative Decree 81/2008 mandates specific health surveillance managed by the Occupational Physician.
- Applies to workers exposed to Legionella in a non-sporadic manner (cooling-tower technicians, plant maintenance, nursing-home and hospital staff)
- Pre-employment and periodic medical visits (frequency set by the Occupational Physician)
- Targeted screening: respiratory history, possible serology, fitness-for-task evaluation
- Up-to-date register of exposed workers, available to ASL and Physician
- Aggregate anonymised data reported at the periodic meeting (art. 35)
Penalties for failure to assess
Criminal and administrative sanctions under Title XII of Legislative Decree 81/2008 for the most frequent Legionella biological-risk breaches.
| Article | Breach | Sanction |
|---|---|---|
| Art. 55 §1(a) | Failure to assess biological risk | Imprisonment 3-6 months or fine 2,500-6,400 euro (Employer) |
| Art. 55 §3 | Incomplete or non-updated DVR | Fine 1,500-6,000 euro |
| Art. 55 §5(d) | Failure to train exposed workers | Imprisonment 2-4 months or fine 1,315.20-5,699.20 euro |
| Art. 290 | Non-compliance with technical protection measures | Imprisonment 3-6 months or fine 2,500-6,400 euro |
| Legislative Decree 231/2001 art. 25-septies | Negligent injury or death from legionellosis | Pecuniary sanction up to 1,549,370.69 euro for the entity + interdictive measures |
Decree 81/2008 + Guidelines: integrated compliance
The Consolidated Act sets the legal obligation; the State-Regions Agreement of May 7, 2015 provides the technical method to discharge it.
Legislative Decree 81/2008
Establishes the biological-risk-assessment obligation and the related sanctions. Binding statutory rule.
2015 State-Regions Guidelines
Provides operational thresholds (1,000 and 10,000 CFU/L), sampling frequencies and remediation procedures. Technical standard recognised by Italian case law as "good practice".
FAQ — Decree 81/2008 and Legionella
The seven questions most often asked by international Employers and RSPP regarding biological Legionella risk.
Must every Employer in Italy assess Legionella risk?
Yes, but only where potential exposure to aerosolised water exists: showers, cooling towers, humidifiers, fountains, hot tubs. A low-use office with only potable water has minimal risk, but it must still be declared in the DVR.
What does 'Group 2 biological agent' mean?
Art. 268 of Legislative Decree 81/2008 classifies biological agents in four groups by hazard. Group 2 (Legionella spp.) can cause disease and presents a risk for exposed workers, but is not normally spread in the community and effective prophylaxis/treatments exist.
Should the Legionella DVR be updated after each sampling round?
Sampling reports are retained as DVR annexes. The risk assessment must be formally updated when significant positivities (≥10,000 CFU/L), plant changes or suspected clinical cases emerge.
Who enforces Legislative Decree 81/2008 on Legionella?
Enforcement bodies are the National Labour Inspectorate (INL), local health authorities (ASL — PISLL/SPSAL services) and the Regional Environmental Protection Agencies (ARPA) for environmental matrices. In clinical cases the ASL Prevention Department is also involved.
Do Legislative Decree 81/2008 and the 2015 Guidelines conflict?
No, they are complementary. Legislative Decree 81/2008 sets the legal obligation to assess biological risk; the State-Regions Agreement of May 7, 2015 provides the technical methods and intervention thresholds to discharge that obligation for Legionella.
Do exposed workers require specific medical examinations?
For non-sporadic exposure (cooling-tower technicians, plant operators, healthcare staff) the Occupational Physician defines health surveillance with periodic visits and, where appropriate, serological tests.
Can I be held criminally liable for a legionellosis case?
Yes. Where failure to assess risk or to implement suitable preventive measures is established, the Employer and supervisors face negligent-injury or manslaughter charges (arts. 589-590 of the Italian Penal Code); the entity is liable under Legislative Decree 231/2001.
