Why Are Low Location Lighting (LLL) Measurements Necessary?


According to SOLAS 2004, Low Location Lighting (LLL) systems must be installed on all passenger ships carrying more than 36 passengers, with the objective of clearly identifying the routes of escape in the case of an emergency situation.

According to the IMO Resolution A.752 (18), Low Location Lighting systems should be visually examined and checked once a week by the crew and a record should be kept. Additionally, at least once every 5 years, all Low Location Lighting must have its luminance measured by an Approved Service Supplier.

The inspection and measurement of Low Location Lighting systems is a mandatory requirement, in order to verify the compliance of these safety signs with international regulations and ensure that luminance levels meet the required standards and remain visible under emergency conditions.

 

How Does a Low Location Lighting Measurement Work?

During a Low Location Lighting measurement, the luminance or light output of the LLL system is assessed. The primary goal of a Low Location Lighting measurement is to verify that the lighting output of the LLL system meets the required standards for visibility and effectiveness. It ensures that the safety signs remain clearly visible and legible during emergency situations, such as power outages or low light conditions.

The measurement approach may vary depending on the type of Low Location Lighting system being assessed.


LLL Measurement Equipment

Accurate measurement of lighting output requires the use of specialized and certified equipment, such as a non-contact luminance meter. This equipment is specifically designed for Low Location Lighting measurements, ensuring precise and reliable readings. It guarantees that the measurements accurately reflect the lighting capabilities of the LLL system.

LLL Measurement Points

A predetermined set of measurement points must be established, covering critical areas where the Low Location Lighting system is installed. These points are strategically selected to represent various spaces and pathways within the vessel.

Here are some commonly identified measurement points:

Escape Routes:

Measurement points installed along escape routes, such as stairwells, corridors, and passageways, are critical for guiding occupants to safety during emergency situations.

Exits and Emergency Doors:

Measurement points near exits and emergency doors are of utmost importance as they indicate the way to evacuate the vessel.

Emergency and Fire-Fighting Equipment Locations:

Measurement points at locations where emergency equipment, such as emergency escape breathing devices, fire extinguishers, and muster and embarkation stations access doors, are situated.

Hazardous Areas:

Measurement points at specific areas on the vessel that pose potential hazards, such as engine control rooms, engine rooms, fuel storage areas, or machinery spaces.

Passenger Accommodation Spaces:

Measurement points are also identified in passenger accommodation areas, including cabin corridors, lounges, dining areas, and entertainment zones.

Public Areas:

Measurement points in public areas such as lobbies, reception areas, and gathering spaces also have designated measurement points.

The measurement equipment is used to capture luminance values at each measurement point, ensuring accurate and reliable data collection. This information forms the basis for assessing compliance and identifying areas that require improvement.


LLL Analysis and Reporting:


Upon completion of the Low Location Lighting measurement survey, the collected data is analyzed and compared with regulatory standards and requirements. A report must be delivered, highlighting compliance status, areas of concern, and recommended actions to enhance safety signage effectiveness.

The report encompasses all the readings obtained during the measurement process. If upgrades or modifications are necessary to meet regulatory standards, they are clearly outlined in the report. This document serves as a valuable guide for Ship owners, providing actionable insights to maintain or enhance the effectiveness of their Low Location Lighting systems and create a safe environment for passengers and crew members during critical situations.

In certain cases, the Low Location Lighting (LLL) system does not meet the necessary specifications. When this occurs, the replacement or upgrade of the inadequate Low Location Lighting system is essential to ensure compliance with regulations. Everlux has extensive knowledge in the installation and renewal of LLL systems for a wide range of vessels. With our expertise and dedication, we ensure that your Low Location Lighting system is brought up to the required standards, guaranteeing the safety of your vessel and its occupants.
