2.9 Safety and handling notice
Raman Rxn2 analyzers incorporate a 532 nm, 785 nm, or 993 nm laser excitation source. Take the following precautions whenhandling the analyzer and probes when the laser is ON:• Before making fiber connections and probe inspections, use the key on the front of the Raman Rxn2 to turn OFF the laser
power.
• Follow the laser safety instructions for the probe in use.
• Do not look directly into the fiber probe output (when the optic is disconnected) or the output (window) of any probes.

2.10 Laser safety
Laser light presents special safety hazards not associated with other light sources. All laser users, and others present, need to beaware of the special properties and dangers involved in laser radiation. Familiarity with the Raman Rxn2 and the properties ofintense laser radiation will aid in the safe operation of the Raman Rxn2. The Raman Rxn2 may contain a 532 nm, 785 nm, or
993 nm laser. Refer to your system specification information to determine which laser you have. The combination of intense
monochromatic light concentrated in a small area means that, under certain conditions, exposure to laser light is potentiallyhazardous. In workplace environments, a laser safety program provides environmental, training, and safety controls which may
reduce the risk of laser-related injuries or workplace damage. For more assistance with taking appropriate precautions andsetting the proper controls when dealing with lasers and their hazards, refer to the most current version of ANSI Z136.1 for Safe
Use of Lasers or IEC 60825-14 for Safety of laser products. The Raman Rxn2 analyzer has hardware safety controls to reduce therisk of laser-based injuries including an interlock and a spring-loaded protective cap covering the laser output of the fiber-optic
cables.
The beam is routed from the rear panel of the instrument via a fiber optic patch-cord. In the unlikely event that the fiber optic
probe cable is removed, the interlock is overridden, and the spring-loaded protective cap is overridden, there will be a laser beam
exiting the analyzer unit. This beam has a beam diameter of 103 µm and a numerical aperture (NA) of 0.29.
The table below provides the fiber core size and mode and the nominal ocular hazard distance equation for the case of laser
exiting directly from the analyzer unit.

Φ = Maximum Power in Watts (W)Another nominal hazard zone calculation needs to be performed to account for the scenario when the analyzer is equipped witha probe. Depending upon the probe utilized, the beam diameter, numerical aperture of the fiber optical cable to the probe head
and focusing characteristics of the probe head, the nominal hazard zone calculation will change depending upon if the potential
exposure point is at the tip of the probe or at a broken optical fiber. Refer to the specifications section in the pertinent
Endress+Hauser Raman probe operating instructions for the appropriate information to complete the nominal hazard zone
calculations pertaining to other exposure points.
CAUTION

Laser beams can cause ignition of certain substances such as volatile chemicals. The two possible mechanisms for ignition
are direct heating of the sample to a point causing ignition and the heating of a contaminant (such as dust) to a criticalpoint leading to ignition of the sample.
WARNINGThe Raman Rxn2 uses a Class 3B laser as defined in ANSI Z136.1. Direct eye contact with the output beam from the laser
will cause severe damage and possible blindness.

Use of controls or adjustments or performance of procedures other than those specified in this manual may result inhazardous radiation exposure.

For more assistance on appropriate precautions and setting the proper controls when dealing with lasers and their hazards,
refer to the most current version of ANSI Z136.1 for Safe Use of Lasers.

Safety Instructions

2.10.1 Optical safety
The Raman Rxn2 is outfitted with a Class 3B laser. Lasers at 785 nm and 993 nm present further safety concerns because theradiation is nearly invisible. Always be aware of the initial direction and possible scattering paths of the laser. The use of OD3 orgreater safety glasses is highly recommended for 532 nm and 785 nm excitation wavelengths and OD4 or greater for a 993 nm
excitation wavelength.

A0048421

Figure 2. Laser safety glasses

2.10.2 Electrical safety
