Factors Influencing the Need for Lightning Protection 1

Factors Influencing the Need for Lightning Protection

Building Type:

In terms of lightning risk, not all buildings are created equal. Here’s how different commercial structures vary in their vulnerabilities:

High-rise structures: Lightning strikes typically target the tallest point, making skyscrapers and other tall constructions more vulnerable to direct attacks. Furthermore, the metal cladding or frames frequently seen in high-rises can act as conductors, increasing the danger of damage.

Buildings with metal roofs or cladding are good candidates for lightning strikes because metal conducts electricity effectively. The resultant electrical surge can spread throughout the structure, damaging electrical equipment and potentially starting fires.

Buildings Housing Sensitive Electronic Equipment: Modern organisations rely extensively on sensitive electronic equipment to run their operations. A direct lightning strike or even an indirect surge can severely damage servers, computers, and other electronic devices, resulting in costly repairs, data loss, and operational disruptions.

Local Lightning Frequency:

Building Codes and Regulations:

Certain structures in Malaysia are required to have lightning protection under certain building standards and regulations.  The Department of Standards Malaysia (DSM) issues guidelines and standards for lightning protection systems (MS IEC 62305: Protection against Lightning – Part 1: General Principles). Familiarising yourself with these requirements might help you assess whether your building falls into the category that necessitates a lightning protection system.

Information Beyond the Basics:

While numerous websites cover these factors, let’s dig deeper into two sometimes disregarded considerations:

A full risk assessment performed by a competent lightning protection professional can give a more extensive appraisal of your building’s susceptibility to lightning strikes. This rating takes into account your building’s location, kind, construction materials, and neighbouring items. It can help you make informed judgements regarding the kind of protection your company need.

Maintenance and Upkeep: Lightning protection systems, like all other safety measures, require regular maintenance and upkeep to ensure peak effectiveness. Neglecting maintenance might reduce the efficacy of the system and leave your building susceptible. TAKO provides comprehensive maintenance programmes to ensure that your lightning protection equipment works correctly.

Beyond the Basics: When do you need lightning protection on a building?

While the parameters described above provide a good starting point, here are some additional considerations to decide when lightning protection becomes an essential requirement for your building:

Business Continuity: Lightning strikes can create significant downtime for enterprises. If your activities rely largely on sensitive electronic equipment or require a constant power supply, even a modest spike might result in considerable losses. Investing in lightning protection is critical to ensuring business continuity and reducing downtime risks.

Building Occupancy: Buildings having a high occupant density, such as schools, hospitals, or public gathering areas, necessitate greater safety precautions. Lightning strikes can endanger human life, hence effective lightning protection systems are critical in keeping residents safe during a storm.

Insurance Requirements: Some insurance companies may provide discounts or mandate lightning protection systems for structures in high-risk areas or for specific uses. Familiarising yourself with your insurance policy and any lightning protection needs can help you make more educated decisions.

By carefully weighing these extra criteria with the conventional considerations, you may determine when lightning protection is a must-have safety measure for your building’s occupants and business activities.

Does my building need a lightning protection system?

There is no one-size-fits-all solution, but several factors impact whether your building needs lightning protection:

1. Building type:

High-Rise Structures: Lightning strikes the highest point, making skyscrapers and towering buildings more vulnerable.
Metal roofs or cladding conduct electricity, making them prime targets.
Lightning strikes can cause direct or indirect damage to servers and computers, resulting in business outages.
2. Local Lightning Frequency:

Areas with more lightning activity pose a larger threat. Check your area’s lightning risk zones.

3. Building Codes and Regulations.

Your local building codes may require lightning protection for specific construction. Check with the Department of Standards Malaysia (DSM) for applicable rules (for example, MS IEC 62305).

What conditions determine if lightning protection is required?

Building Type (High-rise, metal roof, sensitive equipment).
Local Lightning Activity (Frequency and Risk Zones)
Building Codes and Regulations (local Mandates)

What height is lightning protection required?

There is no one height requirement that requires lightning protection. It frequently depends on the surrounding environment and municipal restrictions. A risk assessment can evaluate whether your building’s height makes it vulnerable.

What is the standard for building lightning protection?

The International Standard (IEC) 62305 series specifies rules for lightning protection systems. Your local building codes are likely to include special standards or adjustments. (Example: Malaysia’s MS IEC 62305)

Can an electrician install lightning protection?

While electricians are electrical experts, implementing lightning protection systems necessitates specialised knowledge and training. For correct installation and certification, it is suggested that you work with a lightning protection specialist business.
