In addition to the chemical hazard signage which provides the investigator’s name and emergency telephone numbers, all rooms containing class 3b and class 4 lasers must display one or more of a laser safety danger sign, laser safety caution sign, or a laser safety notice sign used for repair shops. Your responsibility is outlined in the SFU Laser Signage Procedure.
To obtain a laser sign for your door, you are welcome to contact Monica Szczepina at 778-782-6740 or at firstname.lastname@example.org. To print your own temporary sign, you can click on the class of sign that you need (3a, 3b, or 4), print it in colour, then use a black felt pen to write in the correct wavelength and power for your laser. Don't forget that you still need to advise the LSO of the lasers you have.
