Safety Message to Operators of Federal Signal Electronic Sirens and Light/
Sound Systems
The lives of people depend on your safe operation of Federal products. It is important to read and follow all
instructions shipped with the products. In addition, listed below are some other important safety instructions
and precautions you should follow:
Qualifications
•
To properly use an electronic siren and speaker(s), you must have a good understanding of general
vehicle operation, a high proficiency in the use of safety warning equipment, and thorough knowledge
of state and federal UNIFORM TRAFFIC CODES.
Sound Hazards
•
Your hearing and the hearing of others, in or close to your emergency vehicle, could be damaged
by loud sounds. This can occur from short exposures to very loud sounds, or from longer exposures
to moderately loud sounds. For hearing conservation guidance, refer to federal, state, or local
recommendations. OSHA Standard 1910.95 offers guidance on "Permissible Noise Exposure."
•
All effective sirens and horns produce loud sounds (120 dB) that may cause permanent hearing loss.
Always minimize your exposure to siren sound, roll up your windows and wear hearing protection.
Do not sound the siren indoors or in enclosed areas where you and others will be exposed to the
sound. Only use the siren for emergency response situations.
Sound Limitations
•
Before using the vehicle, check to see if the siren speakers are concealed from view. If the siren
speaker is not in clear view on the front of the vehicle, use extra caution when operating the vehicle. A
concealed siren speaker installation is less effective at warning others.
•
Maximum sound output will be severely reduced if any objects are in front of the speaker. If your
installation has obstructions in front of the speaker, drive even more cautiously.
•
Frequently inspect the speaker to ensure that it is clear of any obstruction, such as mud or snow,
which will reduce maximum sound output.
