Laser Safety Checklist

To reduce the likelihood of exposure of the eye or skin to hazardous levels of laser radiation:

	Ensure that laser operators are properly trained on laser and eye safety.
	Post a sign outside your lab to indicate the use of a laser.
	Restrict access to laser-trained personnel, especially for areas where high power lasers are being used.
	Select a laser with the lowest laser output that meets your application or set-up requirements.
	Install the laser at a fixed level (below eye level).
	Do not stare directly into or expose your eyes to a laser beam, even for weak powers or short exposure times.
	Do not point the laser at anyone (especially in the eye).
	Wear protective eyewear adapted to the power and wavelength of the laser (mandatory for Class IIIB and higher lasers). Remember, the temporary discomfort of wearing protective eyewear outweighs the discomfort from permanent eye damage.
	Use laser alignment cards for UV and IR lasers in order to locate the beam during alignment procedures. Lasers in these ranges often appear to be weak intensity visible lasers.
	Enclose the beam’s path as much as possible to avoid direct exposure or reflection.
	Avoid beams coming out of a setup by using beam dumps, screens or curtains.
	Never wear rings, watches or bracelets when operating a laser to avoid unwanted reflections.
	For Class IIIB and higher lasers, install a key switch or interlock circuit feature, if available.
