Danger Sudden Drop Signs | Hazard Signs
Product Summary
Maintain a safe and compliant work environment with our high-visibility Danger Sudden Drop Signs. Designed to warn personnel and visitors of unexpected changes in floor level, these hazard signs are essential for reducing the risk of trips, falls, and serious injuries on construction sites, industrial workplaces, and public access areas. Featuring bold text and highly recognizable warning symbols, these signs deliver critical safety information at a glance.
Compliant with the Health & Safety (Safety Signs and Signals) Regulations 1996 and conforming to BS 5499 standards, our Danger Sudden Drop Signs are part of a wider hazard signage range that includes high voltage signs, slippery surface signs, toxic hazard signs, and biohazard warnings. Use them to build a comprehensive safety signage system that protects your workforce and meets legal safety obligations.
Material & Print Options
Each sign is available in two professional-grade material options to suit different site conditions:
- Adhesive Vinyl: A flexible, self-adhesive option ideal for smooth, clean indoor surfaces. Quick to apply and perfect for temporary or low-impact environments.
- 3mm Rigid PVC: A durable, weather-resistant plastic suitable for long-term use in both indoor and outdoor settings. Provides excellent rigidity for wall-mounting and fence installations.
High-contrast printing ensures maximum legibility, even in low-light or high-activity environments. All signs are printed with fade-resistant inks to maintain visibility over time.
Installation Info
Danger Sudden Drop Signs are supplied without fixings, allowing you to choose the most appropriate mounting method for your site. Installation options include:
- Screwing directly into walls, posts, or hoarding boards (wall plugs and screws not included)
- Using adhesive pads or industrial glue for smooth surfaces
- Mounting within frames or holders as part of a modular safety system
Ensure visibility by placing signs at eye level and near any hazardous drop zones or changes in elevation.
