Safety at mass events isn’t just another item on the production checklist. It’s the very condition that allows the event to happen without irreparable consequences. And yet, it’s the area where things get improvised, underestimated, or delegated without proper oversight most often.
In Argentina, recent history has episodes that made painfully clear what happens when safety is handled badly: Cromañón in 2004 marked a before and after in regulation and in the industry’s awareness. Since then, the rules have evolved, oversight has become stricter in many respects, and the legal responsibility of producers and organizers has become much clearer. Even so, the problems persist wherever improvisation gets normalized.
This guide covers the standards every responsible production company has to guarantee, whether the event is a festival of 5,000 people or a corporate event of 800.
Current regulatory framework in Argentina
The regulation of mass events in Argentina operates at three levels: national, provincial, and municipal. There’s no single law that covers everything, there’s a set of overlapping rules you need to know in detail.
National level
Law 19,587 on Occupational Health and Safety and its implementing decree 351/79 establish the basic workplace safety conditions that apply to the production and technical crew working at events. It doesn’t directly cover attendees, but it’s mandatory for those working on setup, operation, and teardown.
Law 23,798 on AIDS and transmissible diseases requires having blood-exposure procedures in place at any event that provides first aid.
For events with alcohol sales, the framework of Law 24,455 and the supplementary regulations of each jurisdiction apply.
City of Buenos Aires level
The Code of Licensing and Inspections of the City of Buenos Aires sets the licensing requirements for public-use spaces and mass events. It covers maximum capacities, emergency exits, signage, extinguishers, and building-structure conditions.
Mass Events Law 1799 of the City of Buenos Aires specifically regulates mass public events, setting obligations for organizers around safety, access control, signage, medical services, and coordination with security forces.
Ruling 419 of the Undersecretariat of Community Control sets the requirements for authorizing events in public spaces: evacuation plan, medical services proportional to capacity, licensed security staff, and prior notification to the police.
The organizer’s legal responsibility
This point is fundamental: in Argentina, the event organizer is civilly liable for any harm attendees suffer during the event. That responsibility isn’t fully transferred to the security company or the venue. The producer who signs as organizer assumes strict liability toward attendees.
That means safety management can’t be delegated and forgotten, it has to be actively supervised by whoever produces the event.
Evacuation plan: the bare minimum that has to exist
An evacuation plan isn’t a document to file away in a folder. It’s an operational protocol that has to be known by all staff before the event.
Mandatory elements of the plan:
Exit mapping. Every emergency exit must be identified on an up-to-date floor plan of the venue. You have to physically verify that they’re unobstructed and operational before opening the doors to attendees. It’s not unusual to find emergency exits blocked by obstacles, padlocked, or with the push bar jammed.
Flow calculation. The plan has to calculate how long it takes to evacuate the space at maximum licensed capacity. The international standard is 2.5 minutes to evacuate an enclosed space. If that time isn’t achievable at the event’s capacity, there’s a design problem that has to be solved before the event, not during it.
Assembly points. Evacuated attendees need to know where to go. The plan defines safe meeting points outside the space, far enough away not to obstruct emergency crews.
Assigned roles. In an evacuation, each member of the production and security team has a specific role: who leads the evacuation of sector A, who coordinates with firefighters at the entrance, who does the final sweep to verify no one is left behind. These roles have to be assigned and practiced, not improvised.
Signage. Emergency lights and evacuation signage have to be visible from anywhere in the space under event lighting (which is usually very low). You test this by switching on the emergency signage with the event lighting active, not with the venue’s lights at full power.
Communication with the public. The protocol must include the exact wording of the evacuation announcement, who delivers it, from which audio system, and in which language if there are international attendees.
Coordination with security forces
For mass events in public spaces or with more than 1,000 attendees, coordination with the City Police (in CABA) or the Buenos Aires Provincial Police (in PBA) isn’t optional, it’s a requirement of the authorization.
Prior notification. Communication with the security forces has to happen at least 15 days before the event. It includes the event plan, expected capacity, opening and closing times, and the security plan.
Coordination meeting. For events over 3,000 people, it’s standard (and advisable) to hold a coordination meeting with the assigned police operations chief to define: external control points, emergency vehicle corridors, the communication protocol between private security and police, and incident management.
Communication channels. On event day, there has to be a direct communication channel between the event’s security director and the police command. Radio, not cell phone, telephone networks collapse in large gatherings.
External perimeter. Police typically operate on the event’s external perimeter. Private security operates inside. The line between the two jurisdictions has to be clear and agreed upon.
Barriers and fencing: designing attendee flow
The design of entry and circulation flow is one of the most underestimated safety variables. Most serious incidents at mass events happen at the access points, crushes, stampedes, structural collapse, not inside the event.
Number of entry points. The number of entry points has to be enough to absorb the flow of attendees within the available opening window. The general rule is one control point per 500 people expected to enter at peak hour.
Flow separation. If the event has different types of attendees (VIP, general, press, accredited), the entry flows have to be physically separated. Mixing flows at the entrance creates friction and crowding.
Steel barriers. Steel barriers of the “New Jersey” or crowd-control type should be installed to create orderly access lanes, not just to mark the perimeter. Designing the access maze is a discipline in itself: it has to allow flow without creating accumulation points.
Front-of-stage safety zone. At large standing events, the area right by the stage requires protective barriers (mosh pit barriers) with security staff between the barrier and the stage, and a protocol for extracting people who collapse. This gets ignored frequently, and it’s where fatalities happen.
Access lighting. Entry and exit points have to be properly lit, especially for nighttime events. Poorly lit access points create control problems and increase processing time.
Private security staff
In Argentina, private security companies must be licensed by the national Ministry of Security (for cross-jurisdictional operations) or by the corresponding provincial authorities. Hiring unlicensed security staff is a violation that can lead to the event being shut down and criminal liability for the organizer.
Staff ratio. The minimum standard is 1 agent per 100 attendees for low-risk events (corporate, without mass alcohol consumption). For music festivals with alcohol and a standing crowd, the ratio rises to 1 per 50 or even 1 per 25 in critical zones.
Staff functions. The security briefing has to be specific to each post: the access-control agent has different functions from the interior agent, the barrier coordinator, and the extraction agent. Generic staff without a specific briefing improvise, and improvisation in security is costly.
Internal communication. All security staff have to have radios on a dedicated channel. The security coordinator has to have visibility of every sector, whether through physical presence, cameras, or constant communication with the sector chiefs.
Incident protocol. Staff have to know the response protocol for the most frequent incidents: fainting, fights, bomb threats, fire. The protocol has to be written, communicated in the briefing, and practiced at higher-risk events.
Medical emergency protocols
Every mass event requires medical services proportional to the capacity and profile of the event. In the City of Buenos Aires, Ruling 419 sets the minimum number of doctors and nurses based on capacity.
Reference minimum staffing:
- Up to 1,000 people: 1 doctor, 2 nurses, 1 transport ambulance
- From 1,000 to 5,000 people: 2 doctors, 4 nurses, 1 intermediate-care unit
- More than 5,000 people: tiered staffing coordinated with SAME
Location of medical posts. Medical care posts have to be at accessible points but not on the event’s main path. Too exposed and they draw unintended traffic; too hidden and they cause delays in care.
Ambulance access. There has to be at least one clear corridor for ambulances to enter from outside to a point near the stage or the area of highest concentration. This corridor has to be marked, free of structures, and blocked to attendee traffic.
AED (defibrillator). For events with more than 500 people, it’s mandatory to have at least one AED available and staff trained to use it. Having it in a box isn’t enough, someone on the team has to know how to operate it.
Referral protocol. The medical team has to know the nearest emergency hospital to the venue and have a direct communication channel with SAME. In Buenos Aires, the SAME emergency coordination number is 107.
Alcohol and substance use. At events with alcohol, the medical team has to be ready to handle intoxication episodes, which are the most frequent. At music festivals, being prepared to treat overdoses is a reality that has to be accounted for, however uncomfortable it is to do so.
What sets a serious production company apart
Safety at a mass event isn’t an expense, it’s an investment in the event’s continuity and in the organizer’s legal responsibility. A serious production company doesn’t wait for the venue or the security company to make every decision. It defines the plan, communicates it, verifies it, and supervises it on event day.
At SOMOS DER we operate with our own safety protocols for each project, we coordinate with security forces and medical services, and we physically verify the venue’s conditions before opening the doors to attendees.
