Decreto Supremo 160: Complete Guide to Chile’s Fuel Safety Regulation and Digital Compliance

Decreto Supremo 160 (DS 160) is the primary Chilean regulation governing the safe handling of liquid fuels (combustibles líquidos or CL), including petroleum derivatives and biofuels. Promulgated in 2008 by the Ministry of Economy and published in 2009, it sets minimum safety standards for production, refining, transport, storage, distribution, and supply operations. Administered by the Superintendencia de Electricidad y Combustibles (SEC), the decree has been updated multiple times, with the latest modifications in September 2025.

For operators, engineers, and businesses in the energy sector, Decreto Supremo 160 is more than paperwork—it’s a practical framework that prevents accidents while opening doors to innovation. Article 5 allows “alternative technologies” that achieve equal or better safety outcomes, making it a bridge between traditional rules and modern digital solutions like IoT monitoring, AI predictive analytics, and automated reporting systems.

This comprehensive guide explains what Decreto Supremo 160 is, its core requirements, who must comply, penalties for violations, and how technology is transforming compliance today. Whether you manage a gas station, operate a fuel terminal, or develop energy tech, you’ll find actionable insights here.

Legal Scope and Objectives of Decreto Supremo 160

Decreto Supremo 160 establishes minimum safety requirements for installations and operations involving liquid fuels to protect people, property, and the environment. It applies to facilities handling CL derived from petroleum and biofuels but excludes certain areas like oil production fields, direct aircraft fueling, and maritime transport.

The core objective (Article 1) is to control risks so that these activities do not pose dangers. It replaced older rules (such as DS 90 of 1996) and provides a unified, risk-based approach. The regulation covers everything from facility design and construction to daily operations, maintenance, inspections, and decommissioning.

Key legal foundation: It draws authority from Law 18.410 (creating the SEC) and DFL 1 of 1978 from the Ministry of Mining, allowing the government to impose duties to prevent harm.

As of 2026, the consolidated version (last updated October 2025) incorporates changes addressing buried tank lifespans, loading procedures, and vapor recovery in pollution-control zones.

Who Must Comply with Decreto Supremo 160?

Compliance is mandatory for:

• Producers and refiners of liquid fuels
• Operators of storage facilities (surface and underground tanks)
• Transport companies using tank trucks or authorized vehicles
• Distributors and retailers, including service stations
• Owners of installations supplying CL to end users

Even smaller operations, such as farms or industrial sites with on-site storage, must meet relevant provisions. Natural and legal persons involved in any stage share responsibility.

Exemptions are narrow and explicitly stated in the decree.

Key Compliance Requirements Under Decreto Supremo 160

The regulation is organized into titles covering general obligations, storage, transport, distribution, and more. Here are the most critical areas:

Storage Installations (Titles III–V)

• Tanks must have secondary containment, overfill protection, and corrosion controls.
• Buried single-wall tanks reaching 30 years of age (from manufacture date) or out of service for over one year must be permanently closed or removed (Article 111, as updated).
• Double-walled tanks and modern monitoring are encouraged.
• Installations require SEC registration, technical plans, and a Manual de Seguridad de Combustibles Líquidos (MSCL).

Transport and Loading (Title VI)

• Tank trucks need SEC inscription, proper chassis condition, safety equipment (extinguishers, chains), and vapor recovery systems (SRV) in designated zones.
• Drivers must comply with rest-hour rules under labor law.
• Loading operations require trained personnel and documented verification.

Operations and Emergency Preparedness

• Every facility needs risk analyses, emergency plans, and trained staff.
• Electrical equipment in hazardous zones must meet explosion-proof standards for the fuel class (Class I for gasoline-like fuels).
• Signage, grounding, and ventilation requirements apply during handling.

Inspections and Certification

• Periodic inspections by authorized entities are required.
• Operators must maintain records and allow SEC access.

Alternative Technologies (Article 5) This clause is pivotal for innovation. Operators can propose new solutions (sensors, automation, etc.) if they demonstrate equivalent or superior safety through risk analysis and technical documentation submitted to the SEC.

Penalties for Non-Compliance

Violations can result in fines, operational restrictions, facility closures, or criminal liability in severe cases (e.g., accidents causing harm). The SEC enforces through inspections and resolutions. Common issues include outdated tanks, inadequate documentation, or unsafe loading practices. Penalties scale with risk level and recurrence, emphasizing proactive compliance to avoid costly downtime or legal action.

How Decreto Supremo 160 Works in Practice: From Rules to Daily Operations

Compliance begins with site registration and risk assessment. Operators develop detailed safety manuals, implement physical protections (containment barriers, fire suppression), and train personnel.

Inspections verify adherence, while ongoing monitoring ensures systems remain effective. The decree’s performance-based elements—especially Article 5—allow flexibility. Instead of rigid prescriptions, it focuses on outcomes: preventing leaks, fires, spills, and exposure.

In 2026, many operators integrate digital tools to streamline this. Real-time data helps demonstrate compliance during audits, reducing administrative burden.

Modern Technology and Digital Compliance with Decreto Supremo 160

Decreto Supremo 160 explicitly supports innovation. Here’s how technology enhances safety and efficiency:

• IoT Sensors for Tank Monitoring: Level, temperature, pressure, and leak-detection sensors provide 24/7 visibility. Fiber-optic or ultrasonic systems detect issues early, directly supporting storage requirements.
• AI Predictive Analytics: Machine learning forecasts corrosion, overfill risks, or maintenance needs, cutting unplanned downtime.
• Digital Twins and Simulations: Virtual models test upgrades or emergency scenarios before physical changes, aiding Article 5 approvals.
• SCADA and Cloud Platforms: Automated data collection feeds into dashboards for instant reporting to the SEC.
• Blockchain for Traceability: Immutable records prove chain-of-custody, useful for biofuels and audits.
• Drones and AR for Inspections: Thermal imaging and augmented reality speed up roof/tank checks and training.

These tools don’t replace the decree—they amplify it. For example, continuous monitoring can justify extended tank life assessments or faster approval of modern double-walled systems.

Real-world example: Terminals in major ports have retrofitted buried tanks with IoT kits, achieving near-zero preventable incidents while meeting the 30-year rule through data-driven justification.

Benefits of Tech-Enhanced Compliance

• Enhanced Safety: Early alerts prevent most spills and fires.
• Cost Savings: Predictive maintenance reduces repair expenses (industry benchmarks show 25–50% reductions).
• Faster Approvals: Digital submissions shorten SEC review cycles.
• Environmental Gains: Reduced evaporative losses and better vapor control support sustainability goals.
• Scalability: Cloud solutions adapt easily for growing operations.

Businesses gain regulatory peace of mind and a competitive edge during Chile’s energy transition toward biofuels and hydrogen.
