EXAMPLE

STANDARD OPERATING PROCEDURE FOR LASER OPERATION




1. Introduction -

Descriptions of Laser

 

System Description:  Model 1000 Nd:YAG laser marker system manufactured by the XYZ Company.                              

                                   This is a Class 1 laser system with an embedded Class 4 Laser.   

Type and Wavelength: 1.064 micro meters

Class: Class 1 with Embedded Class 4.

Intended Application:  Research

Location: Webster Hall, Room XYZ

 

2. Hazards -

List all hazards associated with the laser

 

Eye and skin hazards from direct and diffuse exposures: Eye Hazard from direct, reflected or scattered beam.  Skin hazard

 

·         Electrical Hazards: Inside power supply.

·         Laser Generated Air Contaminants: Target material.

·         Other Recognized Hazards: Fire hazard.

 

3.  Control Measures -

List control measures for each hazard.

Include the following:

Eyewear requirement, include wavelength and Optical Density: Approved laser safety eyewear with OD=5.0+  @1064 nm is required for all personnel inside the controlled area.

 

Additional PPE: Lab coat, long pants, and closed-toed shoes.

 

Location of PPE: OD=5.0+ Glasses are stored in cabinet to left of door prior to entry zone.

 

Description of controlled area, nominal hazard zone and entry controls: Established controlled area using laser barrier and warning signs, Nominal Hazard Zone is 100 meters = entire lab.

 

Reference to Equipment Manual: See Model 1000 Nd:YAG Laser Manual and ANSI Standard Z136.1

 

Alignment Procedures (or guidelines): (See C.2.Part IV, Additional Information - Manual for beam alignment procedures.  The following rules must be observed during the laser alignment: Only two trained personnel are allowed in the area during alignment procedures. All other activities are prohibited in the same room, unless appropriate protection is provided. Only essential personnel with the appropriate personal protective equipment are allowed in the work area. Place Warning Signs at entrances informing visitors of the dangers.  Use low power visible lasers to simulate the path of the high power laser.  When performing alignment procedures, reduce all high power laser beams to the minimum possible power. Avoid beam paths that are at sitting or standing eye level.  Take off all reflective objects (e.g., rings, badges, watches) before performing any work involving the lasers. Terminate laser beams and specular reflection on diffuse reflecting beam blocks. Keep all combustibles, tools, and reflective surfaces away from the beam path.  Make sure you know where the beam is and stay clear.

 

Maintenance Procedures: To be performed only by authorized maintenance personnel with the appropriate personal protective equipment (See Unit's Laser Safety Program, Part I for a list of Authorized Personnel).  Follow Manufacturer's instructions (See Unit's Laser Safety Program, Part VII Additional Information - Manufacturer's Manual). 

 

 

 

 

Power Supply: Work involving access to the power supply is normally done with the system locked and tagged out.  Access to the energized power supply must be done only by qualified personnel using the buddy system.  Workers are directed to review the electrical safety and power supply sections of the manual before any activities involving access to high voltage.

 

Exhaust System:  When functioning normally, the exhaust system will remove all Laser Generated Air Contaminants even with the protective housing open.  Notify Dr. Doe at 555-5555 if you think there might be a problem or contact EH&S at 335-3041.

 

4. Training Requirements -

State specific requirements.

The specific training requirements for authorized personnel are:  Laser safety training is required before personnel will be authorized to be in the controlled area while the beam is accessible.

In case of emergency:

Notify Laser PI / Supervisor          Dr. Doe                                         at ext. 555

 

For Emergency Medical Response call ext. 911

Action to be taken:

Report all incidents to               Dr. Doe                                                at ext. 555

 

Additional Procedures: If accident or injury, complete incident report and submit to Benefit Services
