CHAPTER 1: PRECAUTIONS

Laser Operation Area

Establish and control a dedicated laser operation area. The person responsible for the area (refer

to Laser Safety Officer later in this chapter) must isolate the laser operation area from other work

areas and display signs warning that the laser operation area is off limits to unauthorized person-

nel.

When operating the laser unit, always wear protective goggles having an optical density of at

least 6 at a wavelength of 1064 nanometers.

Appoint a Laser Safety Officer. The Laser Safety Officer (LSO) must provide personnel with

sufficient training so that personnel can operate, maintain and service the laser safely. The LSO

must take charge of the key to the key switch to ensure that the laser is operated only by

qualified and authorized personnel.

Caution and Warning Indications

Make sure proper warning signs and warning lights are installed in and around the laser

installation. Also, make sure access doors to the laser area are interlocked to the laser. Locate

danger labels and other warning/caution notices on the door of the location where this laser will

be installed to indicate that a laser will be used in this location.

The exterior of the laser should be kept clean. Use a dry cloth or, if heavily soiled, use a cloth

moistened with a mild detergent or alcohol. Do not use paint thinner, benzine or acetone.

Do not modify the laser without prior written approval from Unitek Miyachi Corporation.

Before performing any maintenance on the laser, please read Chapter 7, User Maintenance,

thoroughly. Use the appropriate tools for terminating the connecting cables, being careful not to

nick the wire conductors.
