    “Working with Rainbow Safety has transformed our safety sign sales.”

    Purchased several for use around a reservoir where public access is permitted. They provide a clear warning about the contaminated water and make the swimming restriction obvious.

    Good quality sign and ideal for displaying beside our lake when algae is present. Clear wording and noticeable from a good distance.

    A very clear warning sign that explains the danger of blue-green algae well. The Do Not Swim message stands out and is easy for visitors to understand.
