Decreto Supremo 160 is one of Chile’s key safety regulations for installations and operations involving liquid fuels. It applies to activities such as production, refining, transport, storage, distribution, and supply of petroleum-derived liquid fuels and biofuels. The regulation was issued by Chile’s Ministry of Economy and is available through Biblioteca del Congreso Nacional de Chile, while the Superintendencia de Electricidad y Combustibles, commonly known as SEC, plays a central role in supervision and compliance.
For businesses, operators, engineers, fuel distributors, industrial facilities, and compliance teams, understanding Decreto Supremo 160 is not just about avoiding penalties. It is about reducing risks related to leaks, spills, fires, unsafe storage, improper handling, and operational failures. The Ministry of Energy has described DS 160/2008 as a cornerstone regulation for liquid fuel installations in Chile because it sets physical and operational safety requirements designed to minimize risks from leaks and spills.
What Is Decreto Supremo 160?
Decreto Supremo 160, often written as DS 160/2008, approves the safety regulation for installations and operations related to liquid fuels in Chile. Its formal scope covers production, refining, transportation, storage, distribution, and supply of liquid fuels.
In simple terms, it tells fuel-related businesses how installations should be designed, operated, maintained, and controlled so they do not create danger for people, property, or the environment. The regulation specifically refers to petroleum-derived liquid fuels and biofuels, collectively treated as “combustibles líquidos” or CL.
This makes Decreto Supremo 160 important for fuel stations, storage plants, industrial sites with fuel tanks, transport operators, distribution companies, and organizations that handle liquid fuel as part of their operations.
Why Decreto Supremo 160 Matters
Liquid fuels are useful, but they also create serious safety risks when storage, handling, or transport is poorly managed. A leaking tank, damaged pipe, poor ventilation system, missing inspection record, or untrained operator can lead to fire hazards, environmental contamination, operational shutdowns, and legal exposure.
Decreto Supremo 160 matters because it gives Chile a structured safety framework for controlling these risks. The regulation focuses on safe infrastructure, safe procedures, responsible operators, and risk control throughout the fuel supply chain.
For companies, compliance also protects business continuity. A facility that fails inspection may face corrective actions, delays, extra costs, or enforcement measures. A compliant facility, on the other hand, is easier to audit, safer to operate, and better prepared for emergencies.
Who Must Comply With Decreto Supremo 160?
Decreto Supremo 160 applies to natural and legal persons involved in operations related to liquid fuels. This includes businesses that produce, refine, transport, store, distribute, or supply liquid fuels in installations covered by the regulation.
A company may need to pay attention to DS 160 even if fuel is not its main business. For example, a mining operation, factory, construction company, water utility, logistics fleet, or agricultural business may store diesel or other liquid fuels for internal use. If the installation falls within the regulatory scope, safety duties may still apply.
SEC guidance also references DS 160 in relation to smaller liquid fuel installations and tank trucks, showing that the regulation is relevant across different types of fuel infrastructure and operations.
Key Requirements Under Decreto Supremo 160
Safe Design and Construction
One of the main expectations under Decreto Supremo 160 is that fuel installations must be designed and built with safety in mind. This includes considering tank location, materials, containment, piping, ventilation, access, fire prevention, and protection against leaks or spills.
The regulation’s purpose is to ensure minimum safety requirements for installations and associated operations. This means companies should not treat design as a purely technical or cost-driven decision. Safety and regulatory compliance must be part of the project from the beginning.
A practical example is a business installing a diesel storage tank for backup generators. Before installation, the company should review applicable DS 160 requirements, confirm whether registration or declaration is needed, verify tank specifications, plan spill containment, and keep design records available for future inspection.
Safe Operation and Maintenance
Compliance does not end once a tank or facility is installed. Decreto Supremo 160 also covers operations associated with liquid fuel installations, including transportation, storage, distribution, and supply.
Operators should maintain equipment in good condition, monitor for leaks, keep work areas safe, and ensure that personnel understand operating procedures. This includes checking valves, hoses, pumps, tanks, emergency systems, signage, and containment areas.
A common mistake is treating fuel systems as “set and forget” infrastructure. In reality, tanks, pipes, seals, and connections can degrade over time. Preventive maintenance is often cheaper than emergency repair, environmental cleanup, or regulatory enforcement.
Risk Control and Safety Management
The core goal of Decreto Supremo 160 is risk control. The regulation exists so fuel activities can be carried out safely and without creating danger for people or property.
In practice, this means each facility should have a clear understanding of its main hazards. These may include fuel leaks, vapors, ignition sources, vehicle movement, overfilling, poor drainage, incompatible materials, inadequate emergency access, or insufficient staff training.
Companies should develop internal procedures that explain how fuel is received, stored, transferred, inspected, and handled during emergencies. Even when the regulation sets minimum requirements, strong operators usually go further by using checklists, scheduled inspections, incident logs, and corrective-action tracking.
Documentation and Records
Documentation is a major part of compliance. During an inspection, a company may need to show evidence that its installation, operation, maintenance, and safety processes meet applicable requirements.
Relevant documents may include installation plans, maintenance logs, inspection reports, emergency procedures, training records, supplier documents, permits, declarations, and correspondence with SEC or other authorities.
SEC’s published guidance on liquid fuel installations and tank trucks shows that regulated operators may need to pay attention to registration, design, construction, operation, maintenance, and inspection obligations under DS 160.
Good documentation also helps internally. If a manager leaves, a contractor changes, or an incident occurs, records make it easier to understand what was done, when it was done, and what still needs attention.
Transport Requirements
Decreto Supremo 160 is also relevant to liquid fuel transport. SEC guidance states that tank trucks must be designed and constructed according to the standards indicated in DS 160 and must also be operated, maintained, and inspected according to the regulation’s minimum requirements.
For transport companies, this means compliance is not only about the vehicle itself. It also involves driver training, inspection routines, emergency preparedness, documentation, loading and unloading procedures, and maintenance records.
A practical scenario would be a company transporting diesel to industrial clients. The company should verify that the tank truck meets applicable design standards, keep inspection evidence, train drivers on spill response, and ensure that delivery procedures reduce risks during fuel transfer.
Decreto Supremo 160 Compliance Guide
Step 1: Identify Whether Your Operation Is Covered
The first step is to define the fuel-related activities your company performs. Do you store diesel? Do you operate a fuel station? Do you move fuel by tank truck? Do you supply fuel to vehicles or equipment? Do you manage tanks at an industrial site?
Because Decreto Supremo 160 covers production, refining, transport, storage, distribution, and supply of liquid fuels, many businesses may fall within its scope even if fuel is only a support function.
Step 2: Map Your Fuel Installation
Create a clear map of tanks, pipes, pumps, valves, loading points, drainage areas, fire-control equipment, emergency exits, electrical systems, and nearby sensitive areas. This helps identify compliance gaps and operational risks.
For example, if a fuel tank is too close to a building, lacks adequate containment, or has unclear access controls, the risk map will make the issue visible before it becomes a regulatory or safety problem.
Step 3: Review Design and Construction Evidence
Before operating or expanding a fuel installation, review whether the installation was designed and built according to applicable safety requirements. This is especially important for older installations, inherited facilities, or sites where records are incomplete.
SEC has also issued guidance and resolutions related to regularization of existing liquid fuel installations in specific contexts, showing that older or existing facilities may need structured review and correction when they do not meet current expectations.
Step 4: Build a Maintenance Schedule
A strong maintenance program should define what needs to be inspected, how often, who is responsible, and how findings are recorded. Tanks, pipes, hoses, pumps, containment systems, sensors, and emergency equipment should all be included.
The goal is not only to “pass inspection.” The goal is to detect problems early. A small leak found during routine inspection can prevent a larger spill, shutdown, or enforcement issue later.
Step 5: Train Personnel
People are often the strongest or weakest part of compliance. Staff should understand basic fuel risks, safe transfer procedures, emergency response steps, reporting duties, and what to do when equipment looks damaged or unsafe.
Training should be practical. Workers should know where spill kits are stored, how to stop a transfer, who to call during an emergency, and how to document unusual conditions.
Step 6: Keep Compliance Records Organized
Organized records make audits and inspections easier. A company should maintain a central file for DS 160-related documents, including design information, inspection reports, training records, corrective actions, maintenance logs, emergency plans, and communications with authorities.
Digital records can help, but they should be controlled. File names, dates, responsible persons, and version history matter. A document that cannot be found during an inspection may be almost as problematic as a document that does not exist.
Practical Insights for Businesses
A common compliance mistake is waiting until a formal inspection to review fuel safety. Better practice is to run internal compliance checks on a regular schedule. These checks should compare actual site conditions with documented procedures.
Another useful insight is to involve operations staff in compliance planning. Engineers and managers may understand the regulation, but operators often know where real-world problems occur. They may notice recurring hose damage, difficult access points, poor lighting, unclear signs, or unsafe delivery practices.
Companies should also pay attention to regulatory updates. In 2025, Chile’s Ministry of Energy published a public consultation related to modification of DS 160/2008, describing the regulation as a key framework for liquid fuel installation safety. This shows that the compliance landscape can evolve and should be monitored.
