Frequently asked
Where should I mount a high-voltage warning sign?
Install at all access points to substations, equipment enclosures, and hazardous zones—typically on gates, fences, or directly on equipment housing. Ensure the sign is visible from the most likely approach direction.
Is Class 2 reflective worth the extra cost?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
What is the advantage of the lightning bolt symbol?
The pictogram is instantly recognised across language and literacy barriers, making it ideal for sites with multilingual workforces or public access areas where quick hazard recognition is critical.
Can I order reflective signs for an existing installation?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
