L-113: AAHP has awarded this course 12 CE Credits (2016-00-047). ABIH has previously awarded CM credit for this event. The current event contains 7 hours which can be claimed for 1.169 CM Credit. This course is eligible for .7 Recertification points BCSP Category 7. The BLS has awarded 1CM point for this course.

L-222: AAHP has awarded this course 32 CE Credits (2016-00-049). ABIH has previously awarded CM credit for this event. The current event contains 27 hours which can be claimed for 4.509 CM Credit. This course is eligible for 2.7 Recertification points BCSP Category 7. The BLS has awarded 4CM points for this course.

This five-day course is designed for those persons designated as the Laser Safety Officer (LSO) for their facility who also need a solid introduction to lasers.

The first day of the course provides a general overview of types of lasers and how laser light differs from that produced by the sun and other "ordinary" light sources. The participant also learns about laser operation, terminology and beam properties. Common types of lasers including specific gas, solid-state, and diode lasers are discussed and an overview of laser optics and beam delivery systems is included. The discussion of basic laser operation emphasizes those laser characteristics that are important for the LSO to understand in order to perform the laser hazard evaluation.

The next four days of the course consist of an in-depth, analytical presentation of the LSO’s duties and requirements according to ANSI Z136.1, OSHA, FDA-CDRH and state laser standards. After a review of the biological basis, the student will complete an in-depth computational workshop that covers MPEs, AELs, NHZs and ODs. An in-depth discussion of the control of laser hazards is provided.

Options for on-site training programs are presented including video examples and interactive video/computer programming. The course concludes with a session on non-beam hazards associated with laser use (e.g., fumes, shock, and plume) with emphasis on industrial hygiene-based solutions.
