## Exposure of the Hand to Vibration in either Up and Down, Sideways or Forward and Back Directions - * The total time vibration enters the hand per day, whether continuously or intermittently two remaining axes. If one or more vibration axis ex ** Usually one axis of vibration is dominant over the ceeds the total daily exposure, then the exposure limit *** 1 g = 9.81 m/s 2 - has been exceeded. 2001-33 ## PART VI ## NON-IONIZING RADIATION ## Laser Radiation ## Laser radiation - 34 (1) In industries other than medical industries, an employer shall ensure that laser equipment is operated and used in accordance with the following standards: - (a) ANSI Z136.1-2007, American National Stand -ard for Safe Use of Lasers or a standard offering equivalent or better protection; - (b) ANSI Z136.4-2005, Recommended Practice for Laser Safety Measurements for Hazard Evaluation or a standard offering equivalent or better protection; - (c) ANSI Z136.5-2020, Safe Use of Lasers in Edu -cational Institutions or a standard offering equivalent or better protection; aussi limitée que possible et ne dépasse pas les exposi -tions suivantes : ## Exposition aux vibrations affectant les mains dans les directions ascendante, descendante, latérale ou vers l'avant et l'arrière - * La période totale où les vibrations affectent les mains par jour, que ce soit de manière continue ou intermitten -te. *** 1 g = 9.81 m/s 2 - ** Habituellement un axe de vibration est dominant par rapport aux deux autres axes. Si un ou plusieurs axes de vibration dépassent l'exposition totale quotidienne, alors la limite d'exposition a été dépassée. 2001-33 ## PARTIE VI ## RAYONNEMENTS NON IONISANTS ## Rayonnements laser ## Rayonnements laser - 34 (1) L'employeur s'assure que, dans toute industrie autre que l'industrie médicale, l'équipement laser est opéré et utilisé conformément aux normes suivantes : - a) la norme Z136.1-2007 de l'ANSI, intitulée Ame -rican Na…

## 29 CFR 1926 (OSHA) - (2) Protective eye and face protection devices that the employer demonstrates are at least as effective as protective eye and face protection devices that are constructed in accordance with one of the above consensus standards will be deemed to be in compliance with the requirements of this section. - (c) Protection against radiant energy -(1) Selection of shade numbers for welding filter. Table E-1 shall be used as a guide for the selection of the proper shade numbers of filter lenses or plates used in welding. Shades more dense than those listed may be used to suit the individual's needs. TABLE E-1-FILTER LENS SHADE NUMBERS FOR PROTECTION AGAINST RADIANT ENERGY (2) Laser protection. (i) Employees whose occupation or assignment requires exposure to laser beams shall be furnished suitable laser safety goggles which will protect for the specific wavelength of the laser and be of optical density (O.D.) adequate for the energy involved. Table E-2 lists the maximum power or energy density for which adequate protection is afforded by glasses of optical densities from 5 through 8. Output levels falling between lines in this table shall require the higher optical density.
