# Are Smoke Curtains Required at Elevators? A Comprehensive Guide
## Introduction
Elevators are a critical component of modern buildings, providing convenience and accessibility. However, they can also pose significant risks during a fire emergency. One common question among architects, building owners, and safety professionals is: **Are smoke curtains required at elevators?**
In this article, we’ll explore the role of smoke curtains in elevator safety, relevant building codes, and best practices for compliance.

## What Are Smoke Curtains?
Smoke curtains are passive fire protection devices designed to contain and manage smoke movement in a building during a fire. They deploy automatically when a fire alarm is triggered, creating a barrier that prevents smoke from spreading to escape routes, stairwells, and elevators.
### Types of Smoke Curtains:
1. **Vertical Smoke Curtains** – Used in doorways and open spaces.
2. **Elevator Smoke Curtains** – Specifically designed for elevator lobbies and shafts.
3. **Perimeter Smoke Curtains** – Installed around atriums and large open spaces.

## Why Are Smoke Curtains Important for Elevators?
Elevators present unique challenges during a fire:
- **Smoke Inhalation Risk**: Smoke can quickly fill elevator shafts, endangering occupants.
- **Stack Effect**: Elevator shafts act as chimneys, accelerating smoke spread.
- **Firefighter Access**: Smoke control ensures safe elevator use for emergency responders.
Smoke curtains help by:
✔ **Preventing smoke from entering elevator lobbies**
✔ **Maintaining clear evacuation routes**
✔ **Complying with fire safety regulations**

## Are Smoke Curtains Required at Elevators?
The requirement for smoke curtains at elevators depends on **building codes, local regulations, and elevator usage**. Here’s a breakdown of key standards:
### 1. **International Building Code (IBC) & NFPA 101**
- **IBC Section 3006** mandates smoke containment for elevator hoistways in high-rise buildings.
- **NFPA 101 (Life Safety Code)** requires smoke barriers in elevator lobbies to protect means of egress.
### 2. **ASME A17.1 (Elevator Safety Code)**
- Requires smoke control measures for elevator lobbies in certain occupancies (e.g., hospitals, high-rises).
### 3. **Local Fire Codes**
- Some jurisdictions (e.g., NYC, California) have stricter requirements for smoke control in elevators.
**Key Takeaway**: While not all elevators require smoke curtains, they are often mandated in:
✅ High-rise buildings
✅ Hospitals and healthcare facilities
✅ Hotels and residential towers
✅ Buildings with firefighter service elevators

## When Are Elevator Smoke Curtains Mandatory?
Smoke curtains are typically required in:
### **1. Elevator Lobbies**
- If the elevator serves as part of a **pressurized smoke control system**.
- If the building has **more than 3 floors** (varies by code).
### **2. Firefighter Elevators (IBC 3007)**
- Required to have **smoke containment** to allow safe emergency operations.
### **3. Atriums & Large Open Spaces**
- If elevators open into an atrium, **perimeter smoke curtains** may be needed.

## Benefits of Installing Smoke Curtains at Elevators
1. **Enhanced Life Safety** – Prevents smoke from blocking escape routes.
2. **Code Compliance** – Meets IBC, NFPA, and local fire regulations.
3. **Cost-Effective Solution** – More affordable than full pressurization systems.
4. **Space-Saving Design** – Retracts when not in use, unlike fixed barriers.

## Alternatives to Smoke Curtains for Elevators
If smoke curtains are not required, other solutions include:
- **Pressurized Elevator Lobbies** (mechanical smoke control)
- **Fire-Rated Doors & Partitions**
- **Automatic Shutdown Systems** (to prevent elevator use during fires)
---
## How to Choose the Right Smoke Curtain for Elevators
When selecting an elevator smoke curtain, consider:
**Material** – Fire-resistant fabric (e.g., fiberglass, silicone-coated).
**Deployment Mechanism** – Automatic vs. manual activation.
**Compliance** – UL 10D, ASTM E2307, or local certifications.
**Installation** – Must integrate with fire alarm and building management systems.

## Conclusion: Do You Need Smoke Curtains at Elevators?
The answer depends on **your building’s height, occupancy type, and local fire codes**. While not universally required, smoke curtains are a critical safety feature in many structures, particularly high-rises and healthcare facilities.
### **Next Steps:**
✔ Consult your local fire marshal or building code official.
✔ Work with a fire protection engineer to assess your building’s needs.
✔ Ensure proper installation and maintenance if smoke curtains are required.
By understanding these requirements, you can enhance building safety and ensure compliance with fire regulations.
