Question: Does a small church, less than 100 people, require Egress and emergency lighting?Can EM lights be on a circuit with something else?Also, does it need exit signs?

Okay, let's break down the requirements for egress, emergency lighting, and exit signs for a small church, keeping in mind that building codes can vary significantly by jurisdiction (state, county, city). I'll provide general guidance, but it's crucial to consult your local building codes and fire marshal for definitive answers.General Principles (Based on Model Codes like the International Building Code - IBC)



Occupancy Classification

Churches are typically classified as Assembly occupancies (Group A). Even a small church falls into this category.


Life Safety Code (NFPA 101)

The Life Safety Code, published by the National Fire Protection Association (NFPA), is a widely adopted standard that addresses life safety requirements in buildings. Many jurisdictions incorporate NFPA 101 into their building codes.

1. Egress and Emergency Lighting



Yes, generally a church, even a small one, will require egress and emergency lighting.
This is because Assembly occupancies pose a greater risk in an emergency due to the potential for a large number of people needing to evacuate quickly. Egress Lighting

Regular lighting must be provided for all means of egress (paths of travel to exits). This ensures people can see to evacuate.

Emergency Lighting

Emergency lighting is required to automatically illuminate the means of egress if the normal power supply fails. The purpose is to ensure safe evacuation during a power outage.


Specific Requirements (General)



Illumination Levels

Codes specify minimum illumination levels (measured in foot-candles or lux) that must be maintained on the walking surfaces of the means of egress during normal and emergency conditions.


Duration

Emergency lighting systems must provide illumination for a minimum duration, typically 90 minutes (but check your local code).

Automatic Transfer

The emergency lighting system must automatically switch on when the normal power fails.

2. Can Emergency Lights Be on a Circuit with Something Else?
Generally, NO. This is a critical point. Code Requirements

Codes typically require emergency lighting to be on a dedicated circuit or a circuit specifically designed to ensure its reliability.


Why?
Reliability

If the emergency lights are on a circuit with other loads (general lighting, receptacles, etc.), a fault in one of those other devices could trip the breaker and knock out the emergency lights.


Selective Coordination

Emergency lighting circuits are often required to be selectively coordinated. This means that if there is a fault in the emergency lighting circuit, only the breaker serving that circuit should trip, not the main breaker for the entire building.

Permitted Exceptions (Check Local Code)

Some codes might allow emergency lights to be on a circuit with other emergency equipment or equipment essential for safety (e.g., fire alarm panels). A transfer switch may be used if the other items on the circuit are deemed critical.

3. Exit Signs



Yes, exit signs are almost certainly required.
General Rule

Exit signs are required at all exits and along the path of egress leading to an exit. They must be clearly visible and readily understandable.


Requirements



Illumination

Exit signs must be internally or externally illuminated.


Visibility

They must be visible from a reasonable distance (specified in the code).

Directional Signs

If the exit isn't immediately obvious, directional signs are required to guide people to the nearest exit.


Emergency Power

Exit signs are often required to have emergency power backup to ensure they remain illuminated during a power outage.

Key Considerations and Recommendations



Local Building Codes are Paramount

Every jurisdiction has its own building codes, which may be based on model codes like the IBC or NFPA 101, but with local amendments.


Fire Marshal

The local fire marshal is the ultimate authority on fire safety requirements. Contact them early in the process to discuss your specific situation.

Licensed Professionals

Engage a qualified architect, electrical engineer, and/or fire protection engineer. They can design the egress and emergency lighting system to meet code requirements and ensure the safety of your congregation.


Documentation

Keep detailed records of all inspections, testing, and maintenance of the emergency lighting system.*

Regular Testing

Emergency lighting systems must be regularly tested to ensure they are functioning properly. The frequency of testing is typically specified in the building code.

In summary, while a small church might seem like it could have relaxed requirements, the fact that it is an assembly occupancy means that life safety considerations are very important. You almost certainly need emergency lighting, exit signs, and you must ensure that emergency circuits are properly designed and installed.
