Enel considers employee health, safety and general wellbeing to be the most valuable asset, one to be protected both at work and at home, and we are committed to developing and promoting a strong culture of safety throughout the world in order to ensure a healthy work environment. Quality and safety must go hand in hand. All of us are responsible for our own health and safety and that of the people with whom we interact and, as provided for in the Enel Stop Work Policy, they are required to promptly report and halt any situation of risk or unsafe behavior. The constant commitment of us all, the integration of safety both in our processes and in our training, the reporting and analysis of near misses, rigor in the selection and management of contractors, controls over quality, the sharing of experience throughout the Group and benchmarking against the leading international players are all cornerstones to Enel’s culture of safety.

(1) This indicator is calculated as the ratio between the total number of injuries and hours worked in millions, while the Lost Time Injury Frequency Rate (LTIFR) is calculated by as the ratio between the same number of injuries and the number of hours worked/200,000.
(2) This indicator is calculated as the ratio between the total number of days of absence and hours worked in thousands, while the Lost Day Rate (LDR) is calculated by as the ratio between the same number of days of absence and the number of hours worked/200,000.
(3) Injuries with an initial prognosis, as reported on the medical certificate issued, of greater than 30 days, or with a confidential prognosis until the actual prognosis is released, or with an unknown prognosis that, based on an initial assessment by the company/Division concerned, is expected to exceed 30 days. Once the official prognosis is released, the related injury is considered serious only if said prognosis exceeds 30 days. Should a confidential prognosis never be released or an unknown prognosis remain unknown, within 30 days of the event, the injury is to be deemed serious.

Workplace accident statistics

In 2017, the Lost Time Injury Frequency Rate (LTIFR) and Lost Day Rate (LDR) for Enel Group employees were 0.24 and 11.65, respectively. However, while the number of injuries and, consequently, the LTIFR decreased, there was a slight rise in the number of days lost and, as a result, an increase in the LDR. With regard to the employees of contractors, the LTIFR was 0.19 (down about 6% compared with 2016) and the LDR was 9.86 (up 16% compared with 2016).

In 2017, there were two fatal injuries involving employees of the Enel Group and 11 fatal injuries involving Enel Group contractors.

Policy 106 “Classification, communication, analysis and reporting of incidents” establishes the roles and procedures that ensure the timely reporting of accidents, analysis of their root causes, and definition and monitoring of improvement plans. The policies also detail the procedures for disclosing and analyzing near misses that could have resulted in serious harm. In accordance with these policies, all serious and fatal injuries to Enel personnel and the personnel of Enel contractors and other significant, non-serious events have been investigated by a team of experts. Actions for improvement emerging from this analysis are constantly monitored until their completion, and steps have been taken in relation to contractors found to be in breach of contract (e.g. contract termination, suspension of certification, etc.).

Safety in tender processes

Safety is tightly integrated into Enel’s tender process, and we closely monitor our contractors’ performance both upstream by way of our qualification system and ongoing as the contracts progress through numerous control processes.

Within the vendor selection and qualification process, there are specific, strict rules for the selection of companies based on health and safety (H&S) performance, and there is also a pre-qualification audit for high-risk activities. Our vendor rating system is a consolidated process used to monitor activities as a contract progresses. H&S performance is measured using a specific indicator and, since 2015, application of a global model for vendor ratings enables us to also consider the impact of any injuries to contractor employees as a part of the evaluation process.

All companies that work with the Enel Group must share in the various health and safety standards. The general contract conditions that are valid for the entire Enel Group include clauses dedicated to health and safety, which establish penalties in the event of violations of safety standards, and these may include termination of the contract and suspension of qualifications.

For this reason, contractors are involved in many initiatives aimed at promoting a culture of safety.

Infrastructure safety and technological innovation

Innovations in technology are able to improve all H&S processes, beginning with employee training and the implementation of prevention and protection measures and on through the execution and analysis of corrective actions.

In 2017, new projects of safety innovation were introduced and a number of projects continued from 2016.

Intrinsic Safety: a project that began in 2016, centered around the design, analysis and alteration of new and existing machinery aimed at reducing exposure to hazardous situations and workplaces.

Safety Jacket: the project envisages the development of a safety jacket with integrated airbag to supplement existing protections against falls with a new technology that has never been used in an industrial setting.

Drones: the company has begun the use of inspection drones in flues, furnaces and canals in order to prevent risks related to workers accessing these areas directly.

Virtual Reality: ongoing development work on the virtualreality 3D simulator, a project that began in 2015. More specifically, new virtual reality environments were developed for operational training concerning both maintenance and safety.

Virtual Safety Assistant (VSA): an electronic device that uses real-time mapping of the surrounding environment and stored data related to specific activities to help workers implement the prevention and protection measures needed to carry out their jobs safely.


The Enel Group has created a structured health management system based on preventive measures in order to develop a corporate culture centered on the promotion of the physical, emotional and organizational wellbeing and on establishing work-life balance. To this end, the Group carries out local and global awareness campaigns to promote healthy lifestyles, sponsors screening programs aimed at preventing illness, and ensures the provision of medical services. Global programs and initiatives are developed in accordance with the calendar of the World Health Organization and with local needs.

The Enel Group implements a systematic, ongoing process of identifying and assessing work-related stress in accordance with our policies for stress-at-work prevention and wellbeing-at-work promotion. This enables us to identify, prevent and manage stress in the workplace that could afflict either individuals or broader segments of the organization, while also providing a series of indications aimed at promoting a general culture of wellbeing.

Development of the Culture of Safety: communication and training

There were several communication campaigns concerning health and safety during the year, focusing on areas of particular importance to the organization. In particular this year, global communication efforts focused on issues related to personal health and on the most common disorders, such as: hypertension, hepatitis, smoking, risk factors in cardiovascular diseases, skin cancer, etc. These communication campaigns were based both on the publication of news on the company’s intranet and on specific segments on Enel TV and Enel Radio.

In 2017, we provided more than 430 thousand hours of training, in addition to awareness-raising and training activities in order to increase the specific skills and knowledge of workers throughout the Group. The topics covered included online car and motorcycle safety training and safety leadership training for management.
