CGAP Safety DANGER – Toxic Blue-Green Algae Sign, 8x12 in Aluminum, Harmful Algal Bloom Water Safety Sign for Lakes, Ponds & Parks

Harmful blue-green algae blooms (cyanobacteria) can produce powerful toxins that sicken people and kill pets and livestock. When a bloom is detected, you need a fast, clear way to close the water to recreation. This CGAP Safety DANGER sign does exactly that. It reads: “TOXIC BLUE-GREEN ALGAE – WATER UNSAFE FOR HUMANS AND ANIMALS – NO SWIMMING • NO DRINKING • NO PET ACCESS • NO FISHING.”

The professional OSHA-style design and bold DANGER header get attention quickly. The 8x12 inch .040 aluminum construction means the sign won’t turn to mush in the first rainstorm and can be reused each time a bloom occurs. Install the sign near boat ramps, docks, beaches, and trailheads to warn the public before they enter or let their dogs play in contaminated water.

This is a simple, reusable tool for lake associations, parks departments, HOA boards, farm owners, and campgrounds to protect people and animals during algae events.

• DANGER – TOXIC BLUE-GREEN ALGAE – Clearly marks water bodies affected by harmful algal blooms so people understand the water is unsafe for both humans and animals.
• FOUR STRONG “NO” MESSAGES – “NO SWIMMING • NO DRINKING • NO PET ACCESS • NO FISHING” covers the main exposure routes in one easy-to-read line.
• 8×12 IN WEATHER-RESISTANT ALUMINUM – Rust-proof .040 aluminum sign stands up to rain, sun, and temperature swings better than laminated paper or temporary plastic.
• PERFECT FOR TEMPORARY OR SEASONAL POSTING – Pre-drilled holes make it simple to install on posts, fences, or kiosks and just as simple to remove when bloom conditions clear.
• IDEAL FOR PARKS, HOA LAKES & FARM PONDS – Use for public lakes, private subdivisions, campgrounds, and farm ponds anytime toxic algae is detected and water contact must be restricted.
