Grand Valley State University is committed to providing a safe work environment for the health and well-being of its employees and students. We have developed the Laser Safety Manual to support that commitment. The Manual contains policies and procedures, prepared in accordance with laser safety regulations and guidelines to ensure safe use of lasers in GVSU's laboratories and classrooms.
The Manual contains general guidelines and information about GVSUs policies, safe practices, emergency response actions, for using Class 3b and 4 lasers at GVSU. It does not contain procedures and response actions that apply to specific laboratories within a particular building. In cases where hazards are such that a Laboratory Specific Plan is necessary, those will be prepared and maintained by either the Laboratory Supervisor or Principal Investigator.
Faculty and staff, including student employees, working in laboratory areas should become familiar with the information covered in this document. In the event of a lab related emergency, response actions and reporting procedures are provided assure compliance with regulatory requirements and GVSU policies and procedures. Emergency contact numbers should be posted in each lab.
GVSU expects students and faculty who use lasers in experimental research to become familiar with the basic information contained in this Plan. GVSU has delegated the responsibility for providing students with a safe learning environment in academic courses to the appropriate academic administrator and faculty and staff who work with or instruct the students in the laboratories. The Laser Safety Program is administered by the Office of Laboratory Safety and overseen by GVSU's Laser Safety Committee (supported through Office of Research Compliance and Integrity).
Laser pointers have become a very useful tool for presentations and typically present very little risk. However, high powered or improperly labeled lasers can present a hazard to faculty and students. Below are some things to consider before using a laser in your classroom:
- Classification: Lasers fall into four major hazard categories called the laser hazard classifications (Class 1-4). Any laser rated as Class 3b or 4 must be approved by GVSU's Laser Safety Committee. Only Class 1, 2, or 3R (or 3A) laser pointers are permitted for use in classrooms. When possible, select a Class 2 laser pointer. Red/orange pointers are preferred, as they have been shown to have lower eye sensitivity than green lasers.
- Labeling: All lasers pointers should have a label from the manufacturer identifying its hazard classification. Any laser with a missing label should not be used. Older lasers or those purchased from less reputable retailers may have inaccurate hazard classifications. If your laser is not labeled or you feel its rating may be inaccurate contact Laboratory Safety for power testing.
- Safe Use: Never stare into a laser or shine it in the direction of the audience. Avoid pointing the laser toward shiny objects. Never view a laser through optics such as binoculars or a microscope. The laser should turn off when power button released (can't be locked on). Never point the laser at aircraft, cars, buses, buildings or law enforcement officers.
