SAFETY MESSAGE TO OPERATORS OF

  UNITROL ELECTRONIC SIRENS AND

             LIGHT/SOUND SYSTEMS

              WARNING

The lives of people depend on your operation of

UNITROL 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.

Be aware that the use of your visual and audible

signaling devices does not give you the right to force

your way through traffic. Your emergency lights,

siren, and actions are REQUESTING the

right-of-way.

Although your warning system is operating properly

it may not alert everyone. People may not hear, see,

or heed your warning signal. You must recognize this

fact and continue driving cautiously.

Situations may occur which obstruct your warning

signal when natural or man-made objects are

between your vehicle and others, such as when you

raise your hood or trunk lid. If these situations occur,

be especially careful.

To properly use a light system 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.

Qualifications

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

which may, in certain situations, cause permanent

hearing loss. You should minimize your exposure

times and wear suitable hearing protection.

Sound  Limitations

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.

Signaling  Limitations

Driving  Limitations

At the start of your shift, you should ensure that the

warning system is securely attached to the vehicle

and operating properly.

If the unique combination of emergency vehicle

equipment installed in your vehicle has resulted

in the light/siren controls being installed in a

position that does not allow you to operate them

by touch only, 

OPERATE CONTROLS ONLY

WHEN VEHICLE IS STOPPED.

If driving conditions require your full attention, you

should avoide operating the light/siren controls

while the vehicle is in motion.

Continuing  Education

File these instructions in a safe place and refer

to them periodically. Give a copy of these

instructions to new recruits and trainees.

Failure to follow these safety precautions may

result in property damage, serious injury, death

to you, your passengers or to others.
