(1) The design of warning signs must consider the wording, size, and color. The wording
of the sign must be concise, legible, easily understood, and positive. In those cases where the
OB/OD site is sited in an area with a bilingual population, the sign wording must also be bilingual
with the common second language of the local population. The size of the sign is determined by
its purpose, location, quantity of wording, and distance from which it should be legible. The color
of the sign is dependent on the sign's function.
(2) Signs must be kept in good condition, clean, well illuminated and legible. Signs shall
be made of metal, plastic, or durable weather resistant materials.
(3) Danger signs will be used on an OB/OD site. The danger sign will have a white
background with a black rectangle in the top portion. Inside the black rectangle will be a red oval
containing the word "DANGER" in white letters. The size of this part of the sign will vary
proportionally with the overall dimensions of the sign. Figure 4-1 is an example of a danger
placard. Table 4-1 presents danger sign dimensions. The sign wording will be located in the
remaining portion of the sign. The wording will be in black letters on the white background. The
wording must convey all necessary information, but be kept as brief as possible. Phosphorescent
or retroreflective paint will be used in locations where night visibility is required.
