1. Assess the lightning risk according to current standards
The first step to ensuring effective protection begins with an accurate risk assessment. Without this solid foundation, any lightning protection system is likely to be unsuitable for your specific situation.
Why this assessment is crucial: The IEC 62305 series of standards provides a comprehensive framework for rigorously calculating risk. It covers general principles, risk analysis, physical damage and human risks, as well as network protection.
Legal responsibilities are not optional. For industrial sites classified as ICPE (Installations Classées Pour l'Environnement - Classified Installations for the Environment), Lightning Risk Analysis (ARF) and Lightning Technical Study (ETF) constitute a legal obligation, not a simple recommendation.
This analysis assesses the direct and indirect dangers associated with lightning. It takes into account several factors that are crucial for your installation:
- Geographic location and lightning strike density of the site
- Nature and characteristics of the structure (height, materials, use)
- Estimated frequency of lightning strikes in the area
- Presence of critical services or sensitive equipment
- Risks associated with potential damage (fire, explosion, data loss)
You must also consider the specific French regulatory context applicable to your sector. Hospital facilities, data centers, oil sites, and facilities handling explosive materials require an even more rigorous approach.
A properly conducted risk assessment allows you to accurately size your protection system and justify your investments to the authorities.
In practice, this assessment must not remain theoretical. It must incorporate your actual operational and budgetary constraints. The results of this analysis directly determine the required level of protection and the type of equipment to be installed.
Pro tip: Methodically document all input parameters of your risk assessment (precise location, dimensions, materials, occupants) to ensure complete traceability and facilitate subsequent updates during annual checks.
2. Choose systems adapted to each industrial site
No two industrial sites are ever the same. Risks, sensitive equipment, and configurations vary considerably, meaning your lightning protection needs to be customized.
The first thing to understand is the diversity of lightning threats. You face direct impacts on structures and induced overvoltages in electrical networks. These two risks require distinct and complementary protection solutions.
This is where the strategic choice of surge protectors comes into play. The NF C 15-100 standard mandates the installation of surge protectors in industrial buildings equipped with lightning rods or supplied by overhead lines. But this requirement is only the starting point.
The choice between the different types of surge protectors depends directly on your specific context:
- Type 1 for installations directly exposed or on the first line of protection
- Type 2 for intermediate protection in electrical panels
- Type 3 for end protections near sensitive equipment
Your sensitivity to the equipment is a determining factor. Industrial sites with control systems, programmable logic controllers, or critical IT equipment require much more sophisticated protection than a simple storage shed.
Also consider the topography of your site and its lightning strike density. A site in a mountainous area or a region prone to frequent thunderstorms does not benefit from the same level of protection as a site in an urban area with nearby buildings.
The level of protection required at your site determines not only the type of surge protector, but also its calibration and precise location in the electrical installation.
The configuration of your power supply also matters. If you receive power via overhead lines, your primary protection requirements increase significantly. Underground connections offer greater natural protection.
In practice, this adaptation often means working with multiple coordinated layers of protection. A multi-layered protection architecture ensures that each type of threat is controlled at its critical point of entry.
Pro tip: Accurately document the sensitivity of each critical piece of equipment on your site (withstand voltage, operating current) to justify the choice of each surge protector and avoid incompatibilities during subsequent installations.
3. Conduct a complete and documented annual audit
The annual inspection is not a mere administrative formality. It is your guarantee that the lightning protection system is actually working and that your site remains safe from electrical hazards.
Without regular documentation, you lose track of your installation's condition. This creates dangerous gaps in your maintenance history and complicates your compliance demonstrations to authorities.
A complete check should cover all elements of your protection system. This means examining lightning rods, down conductors, surge arresters, and especially the grounding connections that ensure the discharge of current.
Here are the key steps of a structured audit:
- Visual inspection of lightning rods and down conductors
- Checking the integrity of the fasteners and contact points
- Monitoring the condition of surge protectors and their indicators
- Measurement of grounding resistance
- Review of equipotentiality and additional protections
- Identification of any damaged or faulty components
Documenting your results transforms each audit into concrete evidence. A comprehensive and documented annual audit creates an essential historical record to demonstrate your compliance with standards and facilitates the diagnosis of future problems.
Photographs play a crucial role in this documentation. They capture the actual state of your installation and allow for year-over-year comparisons. Photos must be dated and geolocated for complete traceability.
A verification without documentation is not legally valid. Written and time-stamped proof of your verifications demonstrates your commitment to security.
When you identify a problem, document its location, nature, and corrective actions precisely. This thoroughness facilitates subsequent interventions and prevents the recurrence of defects.
An annual inspection is the minimum regulatory standard, but some high-risk sites require more frequent checks. Your inspection schedule should be based on your specific context and incident history.
Pro tip: Schedule your annual checks for the same month each year and store all your reports in a centralized and accessible way to create a long-term tracking record that facilitates audits and maintenance decisions.
4. Use digital tools for traceability and sharing
Manually managing lightning protection documentation creates significant operational risks. Scattered documents, multiple versions, and a lack of centralized tracking complicate compliance demonstrations and slow down interventions.
Digital tools are transforming this reality by creating a comprehensive and accessible traceability system. You save time, reduce errors, and facilitate collaboration between all stakeholders.
A dedicated digital tool centralizes your documentation in a structured way. Every verification report, every inspection photo, and every weather alert is found in one place, accessible in real time.
This means several concrete advantages for your business:
- Instant access to the complete history of each installation
- Secure sharing of reports with clients and authorities without risk of loss
- Time-stamped tracking of all maintenance actions and checks
- Automated alerts so you never forget a mandatory annual check-up
- Simplified collaboration between installers, inspectors and site managers
Modern platforms like LPS Manager centralize all your installation documentation . They allow you to generate professional reports directly from your field data, without manual re-entry.
Data sharing becomes a strategic asset for your customer relationships. Instead of sending a PDF by email, you can share secure access where the customer can view their reports at any time. This demonstrates your professionalism and commitment to transparency.
Digital traceability also creates protection for you. Every action is recorded with its date and author, creating irrefutable proof in the event of a regulatory audit or dispute.
Digital tools transform your raw data into documented evidence, essential for justifying your compliance with standards and facilitating multi-site management.
You can also analyze trends in your equipment portfolio. Which sites have experienced lightning strikes? Which equipment regularly fails? This information helps you optimize your future interventions.
Mobility is another key factor. Accessing your files from the field, consulting historical data on-site, and writing your reports directly on-site becomes possible with a modern mobile application.
Pro tip: Choose a tool that allows you to export your data and provides customizable reports to suit your specific needs, ensuring that you are not locked into a proprietary solution if your needs change.
5. Implement weather monitoring and real-time alerts
Waiting for a storm to arrive without warning exposes your site to unnecessary risks. Active weather monitoring and instant alerts transform your ability to protect people and equipment.
Real-time monitoring works differently from traditional weather forecasting. It specifically targets your location and alerts you as soon as a lightning threat approaches, not 12 hours after it has passed.
Real-time lightning alert services that meet industry standards send alert start and end messages. You know precisely when the storm is approaching and when the danger is subsiding, allowing for tailored management of your operations.
Some services even offer pre-alerts 24 to 48 hours before a storm. This gives you time to plan your operations, stop critical work, or take additional precautions.
Here are the key advantages of active monitoring:
- Accident prevention by immobilizing personnel in exposed areas before the arrival of danger
- Protecting equipment by triggering safe shutdown procedures before an impact
- Reducing inactivity by resuming quickly after the alert ends
- Regulatory compliance by demonstrating your ongoing vigilance
- Event history recording all detected impacts for analysis
The monitoring system operates 24/7 with no local installation required. You don't need any sensors on your site to receive these alerts, which greatly simplifies deployment.
Alerts arrive via various channels depending on your preference. Mobile push notifications, email, SMS, or integration into your management system allow everyone to receive information in the most suitable way.
Real-time weather monitoring transforms your site from a reactive posture to a proactive approach, drastically reducing the risks of lightning-related incidents.
The history of all impacts detected near your facilities creates a valuable database. You can identify periods of high risk, validate the effectiveness of your protection measures, and optimize your maintenance interventions.
This traceability also helps during audits or disputes. You have proof that you had active alerts and that you followed your security procedures.
Pro tip: Configure your alerts to send differentiated notifications according to severity (alert, emergency, end of danger) and regularly test that all your communication channels are working correctly before the storm season.
6. Collaborate with certified professionals through a specialized directory
Finding the right partner for lightning protection work is often a challenge. How can you truly identify a provider's skills, certifications, and reliability among so many available options?
Professional certification changes everything. It means that an independent body has verified compliance with standards, staff training, and technical competence. It's your guarantee of a compliant and safe intervention.
