Warning Caustic Signs | Chemical Signs
Product Summary
Ensure site safety and regulatory compliance with our high-visibility Warning Caustic Signs, specifically designed to alert personnel to the presence of hazardous caustic substances. Ideal for construction sites, industrial facilities, and workplaces handling corrosive chemicals, these signs serve as a critical visual reminder of potential chemical dangers. Clearly marked with bold text and universally recognized ISO 7010 symbols, each sign helps prevent workplace accidents and supports compliance with The Health & Safety (Safety Signs and Signals) Regulations 1996.
Our Warning Caustic Signs play a vital role in any hazard communication strategy alongside other essential signage such as danger signs, high voltage signs, toxic hazard signs, biohazard warnings, and slippery surface signs. Whether you're managing a construction site or coordinating procurement for a manufacturing facility, these signs are an essential part of your workplace safety toolkit.
Material & Print Options
We offer two robust material options to suit your specific environment and application method:
- Self-Adhesive Vinyl: Ideal for smooth, clean surfaces. Applies easily to walls, doors, and equipment for quick hazard marking.
- 3mm Rigid PVC: A durable, weather-resistant option perfect for both indoor and outdoor use. Suitable for harsher environments that require long-lasting signage.
Each sign is printed using high-contrast colours and industry-standard symbols to ensure maximum visibility and immediate recognition, even from a distance or in low-light environments.
