Title Assessment and prevention of ocular risks during the cleaning of buildings using lasers
Original title Evaluation et prévention des risques optiques induits par le nettoyage laser des bâtiments [in French]
Bibliographic information 3rd Quarter 2004, No.196, p.7-19. Illus. 14 ref.
Abstract Cleaning of buildings using lasers is a technique used since the early 1990s replacing conventional processes, which have often used products that were either excessively abrasive for building materials or were dangerous to the operator and/or the environment. Laser cleaning allows the total or selective elimination of black weathering crusts from stone surfaces without causing any harmful effects. Laser radiation can be partially or even totally reflected by the material being cleaned, and this reflection can cause irreversible eye injury. Wearing protective spectacles is therefore essential. However, absorption saturation effects have been observed in some safety spectacles, making them temporarily transparent to laser radiation and unreliable at high energy levels. Various safety spectacles were tested and found not to comply with the claims of manufacturers with respect to spectral transmission and optical densities. Extreme care should be taken when selecting safety spectacles for use by cleaning operators who use lasers.
