Forty-five years ago this November, guests at the MGM Grand Hotel and Casino in Las Vegas woke up to smoke pouring under their doors. By the time the fire was out, 85 people were dead. Most did not burn. They died from smoke inhalation, trapped in guest rooms on upper floors with no way down and no suppression system to stop the fire at its source.

NFPA’s investigation produced one of the most important sentences in fire protection history: With sprinklers, it would have been a one- or two-sprinkler fire, and we would never have heard about it. That sentence should haunt every building owner, developer, and code official in the world. It still does not drive enough action.

What Happened — and Why

The fire began from an electrical fault in a restaurant on the first floor of the 23-story hotel. It was a Friday morning. About 5,000 people were in the building.

The MGM Grand was not an old, neglected structure. It opened just seven years earlier, in 1973. County building codes at the time required smoke detectors, fire alarms, and automatic sprinklers — but the code was not retroactive, so the MGM only had sprinklers in its theater, kitchen, lobby, basement, and top floor. The casino floor and the restaurant where the fire started had none.

The building department had granted the owner’s request to omit sprinkler installation despite the fire marshal’s objections. The cost of full sprinkler coverage? Reports from the investigation indicated that $192,000 more in sprinklers could have prevented the tragedy. The hotel itself generated tens of millions of dollars in profit every year.

Investigators found 83 separate building violations, design flaws, and installation errors that contributed to the fire and the deadly spread of smoke. The fire incapacitated the alarm system. Guests on upper floors received no warning. Helicopters became the only means of rescuing people trapped at the top of the building.

What Changed — and What Did Not

The legislative response was swift. Senate Bill 214 was introduced just fifteen hours after the blaze, ultimately requiring that all structures over 17 meters (55 feet) tall throughout Nevada be retrofitted with sprinkler systems. Since that law took effect, there has not been a fire-related death at any Las Vegas Strip resort.

Las Vegas learned. But the lesson has not traveled far enough.

Today, hotels and apartment buildings around the world remain open without fully automatic fire sprinkler systems. Developers cite the associated costs. Authorities having jurisdiction accept minimum code compliance. Politicians allow exemptions for existing buildings.

The arguments are different. The risks are the same.

The MGM Grand fire was not a failure of firefighting. Crews responded quickly and bravely. The fire had simply grown beyond control before they arrived — a fire that a couple of automatic sprinklers could have contained and extinguished.

The Technology Is Not the Problem

Automatic fire sprinklers have been proven for more than a century. They activate only in the area where heat is detected. They control or extinguish fires in seconds, before smoke fills corridors and stairwells. They protect the people most at risk — those asleep, those unfamiliar with the building layout; and those unable to move quickly.

The barrier is not technology.

A Call to Action

NFPA’s Annual Conference has returned to Las Vegas, the very city that learned, the hard way, what happens when we compromise on sprinkler coverage. It is a fitting moment to ask: what are we still waiting for?

IFSA calls on:

• Building owners and hotel operators to go beyond minimum code requirements and ensure complete sprinkler coverage in every guest room, corridor, and common area.
• Developers of residential high-rises and apartment buildings to treat sprinkler systems as a baseline design requirement, not an optional upgrade.
• Code officials and AHJs close retrofit exemptions that leave older occupancies unprotected.
• National and international code bodies align standards so that no country or jurisdiction becomes a lower-cost alternative to life safety.

Eighty-five people died in Las Vegas on November 21, 1980, because a decision was made to leave parts of a building unsprinklered. The lesson is not complicated. The obligation is clear.

Sprinkler all new hotels. Sprinkler all new residential high-rises. Retrofit the ones that are not.

We know what happens when we do not.
