triangle above an inverted black isosceles triangle. Separate and outline both triangles
with an aluminum color border. Always place the following words in the upper triangle
of either sign:
R.F. RADIATION HAZARD
The user decides what information will be inserted in the lower triangle, except for those
systems determined to be potentially hazardous. For these systems, the lower triangle
will say: "This system may produce potentially hazardous power density levels. See
TM (insert TM that applies) and local standard operating procedures before operation."
d. Biological Hazard Signs. The biological hazard sign is used to signify the
actual or potential presence of a biological hazard and to identify any equipment,
containers, rooms, materials, or experimental animals that contain or are contaminated
with hazardous agents. The sign may be any design in a fluorescent orange or
orange-red color. The background color is optional as long as there is sufficient
contrast for the symbol to be clearly defined. These labels or signs are required to be
affixed as close as feasible to the container, on the equipment by string, wire, adhesive,
or other method that prevents their loss or unintentional removal. The signs are to be
also posted at the entrance to the work areas specified (see Figure 1-11).

e. Safety Instruction Signs. These signs are used when there is need for
general instructions and suggestions pertaining to safety measures such as: reporting
of all injuries or no matter how slight. Safety instruction signs will have a white
background. A green panel will be placed at the top of the sign and within it will be the
white letters giving the safety instructions. The sign wording in black letters, giving
details of the safety instructions will be placed below the green panel.
