Key roles of maritime warning signs

Maritime warning signs are important in maintaining public safety, especially when natural or environmental changes present unseen hazards. Signs like “Warning Hazards Increase After Floods and High Tides” alert water users to the shifting conditions caused by weather and tides, which can introduce floating debris, altered currents, and other risks. 

Likewise, our “Warning Navigation Hazards in These Waters” signs are invaluable for vessels operating in waters with submerged obstacles, uneven seabeds, or unexpected currents. This allows operators to avoid collisions with objects that may not be visible from the surface. 

By indicating specific dangers, these signs help individuals understand when extra caution is necessary and prevent avoidable incidents.

Built for longevity in maritime environments

Our maritime warning signs are manufactured to withstand the harsh elements encountered in coastal and marine environments. Constructed from durable materials that resist corrosion, fading, peeling, and cracking, they maintain their visibility and readability over time, ensuring ongoing communication—even under challenging weather conditions. 

This also brings additional savings for local councils, harbours, marinas, and other coastal facilities. Thanks to the durability of HIVIS signs, our customers can reduce the need for frequent replacements and minimise maintenance costs.

Compliance with safety standards

HIVIS maritime warning signs have been reviewed and approved by the NSW Government. Each sign is emblazoned with the NSW Government logo and the related phone number so that boaters can trust the message displayed and contact the relevant authorities in case of an emergency. 

These signs are a trustworthy resource for coastal managers and maritime operators, supporting compliance with safety regulations and enhancing overall water safety.

FAQs

How do I know which sign to use for my location? 

We recommend assessing your area's specific hazards to determine the best signage. For example, areas with shifting tides may need signs warning of increased hazards after high tides, while rocky or shallow areas might require specific signs for navigation and depth hazards.

Can these signs be used in both saltwater and freshwater environments? 

Our signs are designed for durability in various water environments, whether saltwater, freshwater, or brackish conditions. They’re equally suited for use in lakes, rivers, coastal areas, and oceanic waters, offering reliable hazard warnings in any setting.

How far away can these signs be seen? 

It depends on the specific sign’s size, colour, and placement. However, our signs are designed with high-contrast colours and clear symbols to enhance visibility from a significant distance, especially in well-lit areas or daylight. For optimal safety, we recommend placing signs in positions that are unobstructed and easy to spot for boaters and other water users.
