Accidents the Fund does not cover

Last reviewed: September 2, 2026VerifiedFondo del Seguro del Estado

In short

Article 4 of the Workmen’s Accident Compensation Act says which accidents are not compensable. There are three and they fit in a paragraph: when the worker was trying to commit a crime or to injure their employer or another person, or caused the injury voluntarily; when they were drunk, "provided the drunkenness was the cause of the accident"; and when their reckless imprudence "was the only cause of the injury". The two conditions are what matters. Having drunk is not enough: the drunkenness has to be the cause. Having been reckless is not enough either: the recklessness has to be the only cause, so that if something else contributed — an unguarded machine, a supervisor’s order, the state of the floor — the exception, by its own words, does not apply. The Fund’s Administrator decides, and their decision is appealed to the Industrial Commission.

What is it?

It is Article 4 of Act 45-1935, the article listing the excepted accidents: those occurring under the three circumstances the Act describes are not compensable work accidents and give no right to compensation to the worker or their beneficiaries.

Who can do it?

This guide serves any worker whose case the Fund has denied or is questioning by invoking their conduct, and their beneficiaries when a death is in dispute. It also serves the employer who wants to know what the Act excludes, because Article 4 gives the employer no power to decide: the Administrator is who determines it.

Step by step

  1. Step 1: Read the whole article: there are three cases

    Article 4 says that the following are not compensable work accidents and therefore give no right to compensation to the worker or their beneficiaries: "(1) When the worker tries to commit a crime or to injure their employer or any other person, or when they voluntarily cause the injury. (2) When the worker is drunk, provided the drunkenness was the cause of the accident. (3) When the worker’s reckless imprudence was the only cause of the injury." That is the entire article. There is no hidden fourth exception.

  2. Step 2: Drunkenness alone excludes nothing

    The second exception does not say "while drunk". It says "when the worker is drunk, provided the drunkenness was the cause of the accident". That clause is part of the Act’s text, not an interpretation. A worker who had been drinking but whose accident was caused by something else — a scaffold that gave way, a vehicle that hit them, a machine that failed — does not fall into the exception merely for having drunk. The question that decides is one of cause, and it must be answered with evidence of the accident.

  3. Step 3: "Only cause": if anything else contributed, the exception does not apply

    The third exception is the narrowest of the three, because the Act demands exclusivity: the reckless imprudence must have been "the only cause of the injury". It is enough for another cause to have concurred for the exception, by its own words, to fall. That is why the details of the place and the moment matter: what protective equipment there was, what instructions had been given, what state the equipment was in, whether anyone else was involved. The Act does not define "reckless imprudence", and this guide does not give it a definition the Act did not give it.

  4. Step 4: The first exception: crime, assault or self-inflicted injury

    The first exception covers three behaviours and none carries a condition: trying to commit a crime, trying to injure the employer or any other person, or voluntarily causing the injury. Here the Act does not require the conduct to have been "the only cause" or "the cause" of anything: it describes the circumstance and excludes it. It is the most direct of the three exceptions.

  5. Step 5: If you are denied, the decision is appealed

    A denial under Article 4 is made by the Fund’s Administrator, and like any other decision of theirs it can be taken to the Industrial Commission under Article 9. That appeal has its own term and its own procedure, which the guide on appeals to the Industrial Commission explains. What this guide makes clear is what has to be proven for the exception to apply, which is not the same as what often gets said on the shop floor.

Where to do it

There is nowhere to apply: Article 4 is not a procedure, it is the list of exclusions the State Insurance Fund’s Administrator applies within the case you already have open. If the decision excludes you, the forum to review it is the Industrial Commission.

What to do if something goes wrong

If you are told there is no case because you had been drinking, the Act asks for something more: that the drunkenness was the cause of the accident. If you are told there is no case because you were reckless, the Act asks that the recklessness was the only cause. If any other factor concurred in the accident, that exclusivity does not hold. If the denial came in writing, keep it: it is the document that gets appealed. And if the accident ended in death, the exceptions are argued the same way, but it is the beneficiaries who claim.

Common mistakes

  • Believing that having drunk, by itself, closes the case: the Act conditions that exception on the drunkenness having caused the accident.
  • Reading the third exception as "if you were reckless, there is no case", when the text requires the recklessness to have been the only cause.
  • Accepting a verbal denial: what is appealed to the Industrial Commission is the Administrator’s decision.
  • Failing to gather evidence of the conditions of the place, which is exactly what decides whether another cause concurred.
  • Confusing Article 4 with Article 14: 4 excludes accidents; 14 deals with workers the Act does not cover.

Frequently asked questions

How many accidents does the Act exclude?

Three circumstances, in Article 4: attempting to commit a crime or to injure someone (or injuring oneself voluntarily), being drunk when the drunkenness caused the accident, and reckless imprudence when it was the only cause of the injury.

I had been drinking, but a machine caused the accident. Am I excluded?

The Act conditions that exception: it applies "provided the drunkenness was the cause of the accident". If the cause was something else, Article 4’s text does not cover that case. The Administrator determines it and their decision is appealed to the Industrial Commission.

What is reckless imprudence?

Act 45-1935 does not define it, and this guide does not invent a definition. What the article does say is when it excludes: only when that imprudence was the only cause of the injury.

What if I was injured fighting at work?

The first exception covers the worker who was trying to injure their employer or any other person. That exception carries no causation condition in the text. The circumstances of each case are evaluated by the Administrator.

Do I also lose medical care?

Article 4 speaks of the right to compensation. Medical care has its own rule in Article 5, which the five-business-days guide explains: there the Act says the medical assistance the Administrator deems necessary may not be denied under any circumstance.
