Laser Safety Manual

23 Laser Safety Manual D. Emergency Planning Planning for emergencies enables communication of hazards through signage and postings and allows laboratory personnel to develop and follow emergency action plans. Postings and Signage For information regarding general lab safety postings and signage and emergency action plans, refer to “ Emergency P lanning” in the Laboratory Safety Manual The ANSI Z136 series requires that lasers and laser systems have appropriate warning labels and that the rooms in which they operate bear appropriate warning signs. Signs for laser laboratory doors are provided by the LSO; however, laboratory supervisors and laser users/operators must be familiar with the signage requirements. The signal word “Danger” indicates that death or serious injury will occur if necessary control measures are not implemented to mitigate the hazards within the laser controlled area. This signal work shall be restricted to those Class for lasers multi-kilowatt output power or pulse energies with exposed beams.. The signal word “Warning” shall be used on laser area warning signs associated with lasers and laser systems whose output exceeds the applicable MPE for irradiance, including all Class 3B and most Class 4 lasers and laser systems. The signal word “Caution” must be used with all sign and labels associated with all Class 2 and Class 2M lasers and laser systems that do not exceed the appropriate MPE for irradiance. The signal word “Notice” must be used on signs posted outside temporary laser-controlled areas, such as during periods of service.
