Standard Installation Guideline for Chemical Earthing System
1. Pre-Installation Planning
1.1. Site Survey & Soil Resistivity
Conduct a soil resistivity test using the Wenner Four-Point Method at the intended location to determine the expected depth and number of electrodes required.1.2. Location Selection
Moisture: Choose an area where the soil naturally retains moisture (e.g., near water pipes, shaded...

Cad Welding Pre-Requirements
1. Purpose
Exothermic welding involves a chemical reaction that produces molten copper at temperatures exceeding 3,000°C (5,400°F). This process presents severe hazards including extreme heat, molten metal splash, toxic fumes, and fire/explosion risks. This document establishes mandatory safety protocols to prevent personnel injury and ensure joint quality compliant with international standards.2. Referenced...

Why Adhering to Lightning Protection Standards is Critical for Bangladesh
Bangladesh faces one of the world's most severe lightning threats, particularly during the pre-monsoon and monsoon seasons. With thousands of strikes recorded annually, lightning is not just a natural phenomenon; it's a major cause of casualties, property damage, and power grid disruption. Standard of lightning protection system is necessary because lightning can harm people by...

Ensure The Lightning Safety.
How to ensure the lightning safety?
Lightning safety doesn't mean that you install a lightning air terminal and make a path by conducting metal to the ground. Installation of Lightning Protection System (such as Air-terminal, conductors & ground) on structures only protect the direct lightning. Ensuring the complete lightning safety involves a combination of preparedness, protective...

What is Lightning Protection System
What is Lightning Protection System
A lightning protection system is a designed set of components and equipment installed on top of the building or roof of the structure to protect it from the potentially destructive effects of lightning strikes. The main function of a lightning protection system (LPS) is to ensure a safe and low-resistance path...

Conventional Lightning Protection System
The conventional lightning protection system represents a time-tested approach to fortifying structures against the formidable forces of lightning strikes. Comprising a well-coordinated ensemble of components, this system is designed to efficiently intercept, channel, and disperse the powerful electrical currents associated with lightning, minimizing the potential for damage and harm. At the heart of this system are...

তাল গাছ কি বজ্রপাত থেকে রক্ষা করে?
তাল গাছ কি বজ্রপাত রক্ষা করে?
আপনি উত্তরে হ্যাঁ বা না বলতে পারবেন না। এতে কোন সন্দেহ নেই যে অন্য যে কোন লম্বা বস্তুর মত তাল গাছেও বজ্রপাত হতে পারে, তবে এই ধরনের বজ্রপাতের সম্ভাবনা পরিস্থিতির উপর নির্ভর করে পরিবর্তিত হয়। অন্যান্য গাছের তুলনায় তাল গাছ কি বজ্রপাতে আক্রান্ত হবার সম্ভাবনা বেশী কিনা এবং কেন কীভাবে...

Conventional LPS
A conventional LPS (lightning protection system) refers to a traditional or standard approach to protecting a building or structure from lightning strikes. It typically consists of a set of components designed to intercept, conduct, and safely dissipate the electrical current of a lightning strike. A lightning protection system is a set of components and equipment that...
