A client working in the healthcare industry was looking for a recommendation for a surgical laser area
ANSI Z136.3-2005 is quite forgiving with respect to the engineering controls required in this situation. No one wants a laser to shut down in the middle of a surgery, so there are no requirements to interlock it. Section 4.7.1 suggests conspicuously displaying a warning sign on all doors entering the laser treatment controlled area (LTCA). The signs should be removed or covered when the laser is not in use. In this type of situation, it is common to use illuminated placards that state that the hazard is present when the sign is lit. This scenario represents a "Procedural Area or Entryway Safety Control" as specified in ANSI Z136.1-2007 section 4.3.10.2.2. The client preferred our clean and modern warning system in lieu of bulky illuminated placards.
Laser Safety Systems recommended the following solution:
Our standard LSS-2380 warning module with visual and audible warning abilities mounted cleanly in the wall beside the entry door. The posted warning sign references this module to warn of the present laser state. The warning provides an audible "activation warning" tone for several seconds when first energized by the surgeon and then settles in a silent solid display, or a strobe display that has an audible "tick" similar to the sound produced by a xenon strobe.
$268
Inside the laser treatment area, the surgeon has a warning strobe controller mounted at a convenient location. The surgeon can select On, Off, Strobe, or Solid. The LED illuminated rocker switches provide clear indication of the warning state to the surgeon.
$119
The system power input module is located near a 115V power source. A medical rated wall-wart type power supply (included) provides the 24 Vdc necessary for system operation.
