Safety and environment

In order to achieve Operational Excellency, ExxonMobil goes beyond the applicable environmental laws and regulations, and, thus, adopts high safety standards and state-of-the-art technology in its operations, always keeping the focus on people and on preserving the environment.

Safety and environment

We pay special attention to how our products and operating units might impact employees, neighbors and customers. When used correctly, our products provide enormous benefits to society. To this end, we invest a significant amount of time, effort and capital.

We are mindful of managing the business in order to prevent incidents and to control spills and losses, and also to respond quickly and effectively to incidents resulting from operations, while cooperating with industry organizations and authorized government agencies.

As a major energy supplier, we seek to maximize our contributions to economic growth, environmental protection and long-term social welfare.

Health and Safety

ExxonMobil is committed to operating in a secure manner. This is a principle established in the company's policies: no commercial objective can prevail over the integrity and health of its employees, of anyone contracted in its operations, of its customers, of society in general and over the preservation of the environment.

ExxonMobil acts based on procedures and behaviors, generating excellent results in the areas of Occupational Safety, Health and the Environment. For this purpose, it adopts the OIMS — Operations Integrity Management System — that establishes requirements leading to Operational Excellence in all the company's activities, and Alerta!, which is the accident prevention system that has led to increasingly better results in our incident rates.


The OIMS — Operations Integrity Management System — establishes requirements that lead to Operational Excellence in all of the company's activities.

How does the OIMS work?

For greater understanding, we can compare it to the structure of a building: the programs it supports would be the walls, the roof and the electrical and plumbing systems. The OIMS represents the personnel and organizational commitment that is essential to maintain the workplace and the community in safe, productive and environmentally correct conditions. The System is based on 11 elements:

  1. Leadership, Commitment and Responsibility from Management
  2. Risk Assessment and Management
  3. Design and Construction of Facilities
  4. Information/Documentation of Processes and Facilities
  5. Personnel and Training
  6. Operations and Maintenance
  7. Change Management
  8. Third-Party Services
  9. Incident Investigation and Analysis
  10. Community Awareness and Emergency Preparation
  11. Evaluation and Improvement of Operations Integrity

ALERTA! (WARNING!) - A prevention program adopted by ExxonMobil that acts based on the behavioral factors considered to be the main causes of exposure to risk in professional or personal activities. It is the result of over 25 years of international research and basically uses 5 tools to preserve the physical integrity of employees and contractors:

  1. Incident Investigation (II) - A process that ensures that all possible information about an incident is obtained, assessing the behavioral or work factors in order to prevent recurrence through the implementation of actions and communication of lessons learned.
  2. Near-Incident Investigation (IQI) - Similar to the previous item, differing only in the consequence of the event. Meaning the incident did not occur (“luckily”), there was no loss/damage to people or material, but there could have been, and for this reason it is also investigated.
  3. Observation for Incident Prevention (OPI) - A process that involves two people (observer and observed) in the execution of a task in order to identify inappropriate procedures, tools or behaviors from a safety perspective. After the observation, a meeting is held in which in the local managers participate and that will determine if there is need for any action to be put in place to eliminate possible risks.
  4. Self-Security Assessment (AAS) - A procedure that every employee must perform before carrying out a task. It is a mental and visual assessment to check safety conditions, both in relation to the procedure to be used or their own knowledge and/or skill. If the employee concludes that the conditions are not as desired, they should not start the task.
  5. Task Safety Analysis (AST) - A written procedure describing all the steps of a certain task, the risks associated with each of them and how to minimize or eliminate these risks.

Business Conduct

The means by which we achieve our results are as important as the results themselves. For decades we have constantly communicated this message to our employees. Our ethics policy, as well as all of our other policies, is objective, direct, and applies to everyone, without exception.

Below is a summary of the main policies that must be followed by our employees and contractors:

Commercial Conduct Standards

The Commercial Conduct Standards are at the core of our control system. These policies were launched for the first time almost 40 years ago and have undergone continuous improvement over the years. The policies deal with business ethics, conflicts of interest, antitrust practices, equal opportunities in employment, workplace harassment and performance in the areas of safety, health and the environment.

Reevaluation of Business Practices

The managers also regularly reevaluate and discuss the Commercial Conduct Standards in meetings with employees who are encouraged to submit any problem, question, or concern to their immediate supervisors or to representatives of the Auditing, Human Resources, Legal or Comptroller Departments.

Compliance of Safety, Health and Environmental Standards

Many of our operating units and several of our products, though vital to global interests, involve potential risks to our employees and customers and to the community. Monitoring these risks is a crucial aspect of our business. In 1992, we developed the Operations Integrity Management System (OIMS), a comprehensive and structured process to manage these safety, health and environmental activities. As part of the OIMS, the management, with the support of technical specialists, regularly evaluate the operating units. Every year, about one-third of the company's main operating units is examined by experts from outside the unit under evaluation.

Alcohol and Drug Use

The excessive consumption of alcoholic beverages and the use of drugs or other substances by employees are harmful to performance and safety. The following are unacceptable and expressly prohibited behaviors: the use or possession of illegal drugs; the improper use of allowed medications; the use or possession of unprescribed controlled medications during activities while working for the company or at its facilities, as well as the inability to work as a result from the use of alcohol or drugs. No employee who has a history of substance abuse is authorized to work in a position that is crucial for the safety and well-being of the employees, the public, or the Company.
