The decree addresses the risks associated with handling petroleum-based fuels such as gasoline, diesel, kerosene, and other combustible liquids. These fuels play a critical role in modern economies but also present significant hazards if not properly managed. Fires, explosions, leaks, and environmental contamination are among the dangers that the regulation aims to prevent.
Background and Legal Framework
In Chile, a “Decreto Supremo” (Supreme Decree) is a legal instrument issued by the executive branch, usually signed by the president and the relevant ministers. These decrees are commonly used to regulate specific sectors, establish technical standards, and implement existing laws. While they do not replace legislation passed by Congress, they provide the detailed rules necessary to enforce national policies.
Decreto Supremo Nº 160 was introduced to modernize and unify the safety regulations governing the liquid fuel sector. Prior to its implementation, Chile had several separate rules addressing different parts of the fuel supply chain. However, the rapid growth of the energy sector and increasing industrial activity made it necessary to adopt a more comprehensive regulatory system.
DS-160 therefore consolidated and updated safety requirements for the entire lifecycle of liquid fuels—from production and refining to final distribution at service stations. By establishing standardized procedures and safety measures, the decree sought to reduce accidents and improve oversight across the industry.
Purpose and Objectives of DS-160
The main purpose of Decreto Supremo 160 is to regulate installations and operations involving liquid fuels in order to minimize risks to public safety and the environment. The regulation sets out minimum safety requirements for companies operating in the fuel industry and ensures that facilities are designed, constructed, and maintained according to strict technical standards.
Key objectives of the decree include:
- Preventing industrial accidents, including fires and explosions associated with fuel handling.
- Protecting workers and nearby communities from hazards related to fuel storage and transportation.
- Ensuring safe design and operation of fuel facilities, including storage tanks and pipelines.
- Reducing environmental damage caused by fuel spills or leaks.
- Standardizing safety practices across the fuel supply chain.
- Strengthening government oversight and enforcement within the energy sector.
These objectives reflect the broader goal of balancing economic development with safety and environmental responsibility.
Scope of the Regulation
Decreto Supremo 160 applies to a wide range of facilities and activities involving liquid fuels. The regulation covers the entire fuel supply chain, including:
- Fuel production facilities, where petroleum products are manufactured or processed.
- Oil refineries, which convert crude oil into refined fuels such as gasoline and diesel.
- Fuel storage installations, including large storage tanks and terminals.
- Transportation systems, such as pipelines, tanker trucks, and shipping operations.
- Distribution centers, where fuel is transferred between transport systems and retail outlets.
- Service stations and refueling facilities, where fuel is sold directly to consumers.
By covering all stages of the supply chain, the decree ensures that safety standards remain consistent from production to final consumption.

Technical Safety Requirements
One of the defining features of DS-160 is its detailed technical framework for fuel infrastructure. The regulation outlines specific engineering and operational standards that facilities must follow to minimize risks.
1. Facility Design and Construction
Fuel installations must be designed according to strict engineering guidelines. These include requirements for:
- Structural integrity of storage tanks and pipelines
- Safe distances between fuel installations and nearby buildings
- Containment systems to prevent spills from spreading
- Ventilation systems to reduce the buildup of flammable vapors
- Pressure control and safety valves for storage equipment
These measures ensure that facilities are capable of safely storing and handling large volumes of combustible liquids.
2. Storage Tank Regulations
Storage tanks represent one of the most critical components of fuel infrastructure. DS-160 sets specific standards for tank construction, placement, and maintenance.
Requirements typically include:
- Secondary containment structures around tanks
- Corrosion protection systems
- Leak detection technologies
- Routine inspection and maintenance schedules
These measures reduce the risk of leaks and environmental contamination.
3. Operational Safety Procedures
The decree also regulates the day-to-day handling of fuels within facilities. Operators must follow established procedures when loading, unloading, transferring, or transporting fuel products.
Operational safety rules address issues such as:
- Fuel transfer protocols
- Monitoring systems for tank levels and pressure
- Employee safety training programs
- Documentation and reporting requirements
These procedures help ensure that employees are properly trained and that operations are carried out safely.
Environmental Protection Measures
Liquid fuels pose a significant environmental risk if they leak into soil, waterways, or groundwater. As a result, DS-160 incorporates several environmental safeguards.
Facilities must implement systems designed to detect and control leaks, including monitoring equipment and emergency shutdown systems. Operators are also required to maintain spill containment infrastructure capable of preventing fuel from spreading beyond facility boundaries.
In addition, the regulation requires companies to maintain emergency response plans. These plans outline procedures for responding to accidents, including containment, cleanup, and notification of authorities.
Emergency Preparedness and Risk Management
Another important element of the decree is its emphasis on risk prevention and emergency preparedness. Fuel facilities must develop and maintain comprehensive safety management systems.
These systems include:
- Risk assessments for all fuel operations
- Emergency response procedures for fires and spills
- Employee training for crisis situations
- Coordination with local emergency services
By preparing facilities for potential incidents, the regulation aims to reduce the severity of accidents and improve response times.
Regulatory Oversight and Enforcement
The enforcement of Decreto Supremo 160 is primarily overseen by Chile’s Superintendence of Electricity and Fuels (SEC). This government agency is responsible for monitoring fuel installations and ensuring compliance with national safety regulations.
The SEC conducts inspections, reviews facility documentation, and verifies that companies meet all safety requirements outlined in the decree. Facilities that fail to comply may face administrative penalties, fines, or suspension of operations.
In severe cases, non-compliance can lead to legal consequences, particularly if safety violations result in accidents or environmental damage.
