In the realm of building safety, particularly concerning fire protection, adhering to established regulations is paramount. The South African National Standards (SANS) 10400 outlines comprehensive requirements to ensure that buildings are designed, constructed, and equipped to safeguard occupants in the event of a fire. An essential, yet often overlooked, aspect of these safety measures is the role of “light-blocking coatings” in managing solar PV systems during emergencies. At PVStop South Africa, we are committed to highlighting the importance of these coatings and ensuring this get to the South African market to be readily available on the premises.
The Importance of Light Blocking Coatings

Solar PV systems, while immensely beneficial for sustainable energy, pose unique challenges during a fire. PV panels continue to generate electricity as long as they are exposed to light, creating a potential hazard for fire-fighting efforts. Light blocking coatings, such as those provided by PVStop, offer a crucial solution by de-energizing PV panels swiftly and effectively. This not only enhances the safety of first responders but also aligns with the fire safety regulations outlined in SANS 10400.
SANS 10400: Key Fire Safety Requirements
SANS 10400 Part T specifies the need for buildings to be equipped with adequate fire detection, control, and extinguishing systems. Key requirements include:
- Protection of Occupants: Buildings must be designed to protect all occupants, including those with disabilities, during a fire.
- Minimization of Fire Spread: The spread and intensity of fires must be minimized to protect the building and adjacent structures.
- Structural Stability: Buildings must maintain sufficient stability to prevent collapse, especially in multi-storey structures.
- Smoke Control: The generation and spread of smoke must be controlled to facilitate safe evacuation.
- Emergency Equipment: Adequate fire-fighting equipment and emergency exits must be provided and maintained.
Incorporating Light Blocking Coatings in Evacuation Plans
To comply with SANS 10400 and enhance overall fire safety, it is essential to integrate light blocking coatings into your building’s evacuation plan. Here’s how PVStop can help:
- Availability of Light Blocking Coating: Ensure that light blocking coatings are available on-site for immediate use in emergencies. These coatings are vital for quickly de-energizing PV panels and preventing electrical hazards.
- Clear Emergency Procedures: Include specific instructions in your evacuation plan for applying the light blocking coating to PV panels. Train designated personnel on the correct application methods and ensure they are aware of the coating’s location.
- Coordination with Fire Services: Develop a joint action plan with local fire services, informing them about the presence of PV systems and the availability of light blocking coatings. Ensure they are familiar with the procedure for de-energizing PV panels and the location of emergency shutdown switches.
- Training and Drills: Conduct regular training sessions and fire drills to ensure all building occupants are familiar with evacuation routes and procedures. Specific training on the use of light blocking coatings should be provided to designated personnel.
- Regular Maintenance and Reviews: Periodically review and update your evacuation plan and fire safety measures to comply with the latest SANS 10400 standards. Ensure all safety equipment, including light blocking coatings, is maintained and readily accessible.
At PVStop, we understand the critical role that light blocking coatings play in enhancing fire safety, particularly in buildings equipped with solar PV systems. By incorporating these coatings into your evacuation plan and ensuring compliance with SANS 10400, you can significantly enhance the safety of your building and its occupants during a fire.
