INSTRUCTIONSLASER SHIELDS Laser Safety EyewearKBH-6205PAGE 1 of 2CE EN 207:2017, CE EN 208:2010, ANSI Z136, CE EN 166:2001 User Instructions for Laser Protective EyewearWARNINGSUSE THIS GOGGLE/SPECTACLE FOR DIFFUSE REFLECTION VIEWING ONLYFailure to follow these safety precautions may result in serious eye injury, blindness or even death.This laser protective eyewear is intended to offer protection against accidental exposure to certain lasers and must be marked with the requirements outlined in ANSI Z136and/or CE EN 207 and/or CE EN 208 for the laser in use. Do not use this eyewear for any application other than stated. Do not make alterations to this eyewear. Do not operatelaser unless all users are wearing appropriate eye protection. Consult your Laser Safety Officer or Kentek's Laser Safety Officer if you have any concerns prior to use. Thisproduct allows compliance with ANSI Z136. Familiarity with ANSI Z136 is necessary to ascertain compliance.If the eyewear has a luminous transmittance of less than 20%, it is recommended to increase the intensity of illumination in the workplace; colored filters may reduce userrecognition of warning lights or warning signs. This eyewear may affect color recognition. Laser protective eyewear is only intended to give protection against accidentalradiation; both the limit values and the resistance tests are based on ANSI Z136 requirements and CE EN 207:2017 which requires a maximum period of 5 seconds. Avoid riskof exposure to laser radiation due to reflection from reflective parts (including eyewear), tilting or misalignment of optical components. Inspect eyewear for discoloring, fading,scratches or other damage. If laser protective eyewear is determined to be damaged replace prior to use. Reminder, eyewear that is optical class 3 is not intended for long termuse. The material which may come in contact with the wearer’s skin could cause allergic reactions to susceptible individuals. Laser protective eyewear against high speedparticles worn over standard ophthalmic spectacle may transmit impact, thus creating a hazard to the wearer. Laser protective eyewear which is damaged, has scratchedoculars or has undergone a color change shall not be used anymore. In case of filters with angle dependent transmittance any information shall be given that the protection isonly provided for angles of incidence up to 30°. When protection against high-speed particles at extremes of temperature is required the selected eye-protector should bemarked with the letter T immediately after the impact letter, i.e. FT, BT or AT, where impact letters are F for Low energy impact, B for Medium energy impact and A for Highenergy impact. If the impact letter is not followed by the letter T then the eye protector shall only be used against high speed particles at room temperature. Regardingcompatibility of markings, if the impact symbols F, B or A on the ocular and the frame are not common to both, the lower level will be assigned to complete the eye protector.EXPLANATION OF CE EN 207:2017 MARKINGSA B C D E F520-532 D LB5 KTK SA.
