Texas A&M University Environmental Health & Safety

Overview

Lasers are essential tools in research, teaching, and medical work at Texas A&M. While lasers drive discoveries and innovations, they also present distinct safety risks—such as eye and skin damage, fire, and electrical hazards.
The Laser Safety program is administered by the Laser Safety Officer within EHS. Our laser safety program provides guidance to use lasers safely and confidently, whether you are a new student or a seasoned researcher. Our commitment is to ensure rigorous compliance with the Texas Administrative Code §289.301, which governs laser safety standards in the state.

Key Features of the Program

  • Comprehensive Safety Training - Engage in mandatory training sessions tailored to equip you with the necessary knowledge and skills for safe laser operation.
  • Resource Accessibility - Access a range of resources, including laser safety manuals, guidelines, and applications for laser-use permits, through our user-friendly online platform.
  • Expert Support - Our team is dedicated to providing continuous support and guidance. If you have questions or need assistance, do not hesitate to contact the Laser Safety Officer.

Laser Safety Manual

Procedure Manual for the Use of Lasers

Registration and Permits

Before any Class 3b or Class 4 laser is energized or used on university property, it must be listed on a valid Texas A&M University Laser Permit.

  •  Permit Application: Principal Investigators (permanent faculty or staff) must apply for a permit through the Radiological Safety website. 

  • Permit Renewal: Permits are valid for two years. EHS will send a renewal request and inventory list to the Permit Holder for verification. 

  • Inventory Verification: Every six months, Permit Holders must complete a Permit Verification Report (PVR) to physically locate and confirm the presence of all registered equipment.

Laser Hazard Classifications

Class Hazard Level Description
Class 1 Exempt

Incapable of producing damaging radiation during normal operation

 
Class 2 Low

Visible lasers (<1 mW); the eye's natural blink reflex provides protection.

 
Class 3a (3R) Medium

Potentially hazardous when viewed directly with optical aids

 
Class 3b Medium/High

Hazardous to the eye from direct or specular reflections (5–499 mW)

 
Class 4 High

Dangerous to eyes and skin from direct and diffuse reflections; fire hazard (≥500 mW)

 

Safety Requirements for Users

To maintain a secure research environment, every individual operating within a Nominal Hazard Zone must adhere to strict administrative and engineering controls designed to keep radiation exposure below the Maximum Permissible Exposure (MPE). From mandatory certification to the implementation of lab-specific protocols, the following requirements are the baseline for all laser operations at Texas A&M University.

Mandatory Training

No individual may work within a Nominal Hazard Zone (NHZ) until they have completed two levels of training:
  •  General Laser Safety Training: Conducted by EHS and required every two years. 
  • Lab-Specific Training: Provided by the Permit Holder regarding specific equipment and procedures in their laboratory.

Standard Operating Procedures (SOP)

Each Class 3b and Class 4 laser must have a written SOP available for inspection. This document must include:
  • Operating and alignment instructions. 
  • Specific PPE requirements and eyewear parameters. 
  • Emergency response actions. 

Personal Protective Equipment (PPE)

  •  Eyewear: Must be worn during any operation where a Class 3b or 4 beam is not enclosed.
  • Specifications: Eyewear must be labeled with the appropriate Optical Density (OD) and wavelength. 
  • Maintenance: Eyewear must be inspected every 12 months for reliability and physical integrity.

Incidents and Emergency Contacts

In the event of an exposure injury or a "near miss" involving a laser, please take the following action:

  1.  Seek Medical Attention: Immediately assist the injured individual. 

  2. Notify the LSO: Report the incident immediately to EHS. 

  3. Submit Documentation: A written summary must be sent to the LSO within 5 working days.

Emergency Assistance (Available 24/7)

During Business Hours - Please call (979)-845-2132
After Hours/Weekends - Please call (979)-862-1111

Repairs & Maintenance

EHS must receive a valid certificate of laser radiation registration from any service provider before they perform alignment, calibration, or repairs on Class 3b or 4 systems.
