Lightning Safety in Bangladesh – Complete Guide to Protection Systems (LPS)

By Extensive,

Introduction

Lightning strikes are a serious but often overlooked risk in Bangladesh, especially for industrial facilities, high-rise buildings, and open areas. Every year, lightning causes significant damage to electrical systems, infrastructure, and even loss of life.
Implementing a proper Lightning Protection System (LPS) is essential to ensure safety, compliance, and uninterrupted operations.

What is Lightning Protection System (LPS)?

A Lightning Protection System (LPS) is designed to safely capture and discharge lightning strikes into the ground without causing damage to structures or equipment.

Why Lightning Protection is Important?

  • Protects buildings and assets from direct lightning strikes
  • Prevents fire hazards caused by electrical surges
  • Ensures safety of workers and occupants
  • Reduces equipment damage and downtime
  • Supports compliance with safety standards

Key Components of LPS

  1. Air Terminal (Lightning Rod)
    Captures the lightning strike
  2. Down Conductor
    Safely carries the current to the ground
  3. Earthing System
    Dissipates the electrical energy into the soil
  4. Surge Protection Device (SPD)
    Protects electrical equipment from voltage spikes

Types of Lightning Protection Systems

  • Conventional Lightning Protection System
  • Early Streamer Emission (ESE) System
  • Structural Lightning Protection

Common Mistakes in Lightning Protection

  • Improper earthing system
  • Incorrect placement of air terminals
  • Lack of surge protection devices
  • No regular inspection and maintenance

Standards & Compliance in Bangladesh

Lightning protection systems should follow:

  • BNBC guidelines
  • IEC 62305 standards
  • NFPA 780 standards

Proper design and installation ensure compliance with safety authorities and reduce risk significantly.

When Do You Need LPS?

  • Industrial factories
  • High-rise buildings
  • Warehouses
  • Open field installations
  • Sensitive electrical systems

Conclusion

Lightning protection is not a luxury—it is a necessity in a country like Bangladesh where lightning incidents are frequent. A properly designed and installed LPS can protect lives, assets, and business operations.
