Eye And Skin Exposure; Hazards - COOK Medical H-30 User Manual

Eye and Skin Exposure

The working laser beam of the H-30 is invisible and, if exposed to the eyes, may cause
sight loss. The skin can resist a significantly higher amount of laser energy, but the laser
beam can seriously burn the skin.
A danger exists in any case of:
• Direct laser radiation
• Reflected laser radiation
• Diffused laser radiation
WARNING! All the personnel present in the laser working area must wear
appropriate laser safety eyewear.
Use protective eyewear with either of the following specifications:
• I 2100 L2 (EUR) @ 2100NM
• OD 4 (US) @ 2100NM
Always check the integrity and condition of safety eyewear.
Before wearing protective eyewear, be sure that the protective glass and frame are in
good condition.
The worst-case nominal ocular hazard distance (NOHD) for the H-30 laser system emitting
laser energy from a fiber is 0.5 m. During service operations, there is access to laser
energy emitting directly from the laser source, which raises the NOHD to 15 m.

Hazards

Electrical Hazards
• Only a qualified service technician may remove the enclosure covers. Removing the
enclosures exposes personnel to potential electrical hazards.
• Do not touch areas marked HIGH VOLTAGE. These and surrounding components of
the laser system contain charge voltages of up to 700 VDC.
• Do not operate the laser system if the operating room floor is flooded.
• Service technicians, do not power on the laser system unless all high voltage areas
are dry and not in danger of flooding.
• Inspect power cord before use. Do not use a damaged power cord or a power cord
with a damaged or loose power plug.
