Is there a legal requirement for lightning protection?

Is there a legal requirement for lightning protection?

According to RC 35 ‘Protection of buildings against lightning strikes’, a risk control publication, it is not a legal requirement for all buildings and structures to have lightning protection. Installing a lightning protection system is not only about obeying any necessary regulations.

Is IEC 62305 based lightning protection system?

Lightning Protection System (LPS) BS EN/IEC 62305-1 has defined four Lightning Protection Levels (LPLs) based on probable minimum and maximum lightning currents.

What IEC 62305?

IEC 62305 – Protection Against Lightning, is the apex level document that informs the standards for lightning protection around the world. It is a design standard that comprises of four documents that provide the lightning protection designers with the rules and regulations they require to design an LPS.

How do you maintain lightning protection?

Inspection of all air terminals to ensure none are bent, cracked, broken or otherwise damaged. Refastening and tightening of components and conductors where required. Check for loose, damaged or cut cable connections; check connectors and splice fittings to ensure all leads are firmly connected with no loose ends.

What type of buildings need lightning protection?

Many tall buildings; such as churches and skyscrapers, have lightning protection conductors installed, to avoid significant damage and danger should a lightning strike occur. Lightning conductors are not usually installed on homes, as the likelihood of lightning striking houses is relatively low, but it can happen.

How do you calculate lightning protection level?

Length of Building (L) = 60 Meter. Width of Building ( W ) = 28 Meter. Height of Building (H) = 23 Meter….Calculate Lightning Protection for Building / Structure.

Degree of Isolation Factor
Structure in a large area having greater height 0.4
Structure located in a area of the same height 1
Structure completely Isolated 2

What NFPA 780?

Standard for the Installation of Lightning Protection Systems. NFPA 780 provides lightning protection system installation requirements to safeguard people and property from fire risk and related hazards associated with lightning exposure.

How often should lightning protection be inspected?

every 12 months
Test & Inspection It is important that all lightning protection systems should be tested by a specialist at least every 12 months but we always recommend testing is carried out every 11 months.

How often must an LPS have a visual inspection?

A building’s maintenance staff and contractors working on the building should be trained to protect the integrity of the LPS. Industry recommendations call for a visual inspection to be performed annually, with an in-depth inspection and follow-up quality assurance certification or report provided every 3 to 5 years.

Do all buildings have a lightning rod?

There is no good reason why lightning rods (and the associated assembly consisting of a connection to earth and a ground rod) are not routinely added to houses. However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.

How do lightning rods protect buildings?

lightning rod, metallic rod (usually copper) that protects a structure from lightning damage by intercepting flashes and guiding their currents into the ground.

What is a lightning protection system inspection and maintenance checklist?

A comprehensive Lightning Protection System inspection and maintenance checklist will help building owners comply with existing system certifications, and industry safety standards, while simultaneously ensuring a longer lifespan for their systems. How often should you inspect your lightning protection system?

Why is it important to maintain your lightning protection system?

For a lightning protection system to function as designed in the event of a lightning strike, it is essential that the lightning conductor system is maintained and kept in good order. Lightning Protection Services can be called to carry out one off repairs, eg. Storm damage, vandalism or full upgrades to BS EN 62305.

What is the IEC standard for lightning protection?

Applicable Standards IEC/BS EN 62305 – Protection against lightning IEC 63205 is the recognised worldwide standard for lightning protection system (LPS) design, installation and maintenance. BS EN 62305 is the British edition of the European standard, and is derived from the IEC document.

What are the AS/NZS 1768 lightning protection standards Australia?

The AS/NZS 1768:2007 Lightning Protection Standards Australia provides guidelines for the protection of persons and property from the hazards of lightning. It applies to conventional Lightning Protection Systems consisting of air terminations, down-conductors, earthing systems and surge protective devices.
