6410 Appendix T6

Laser Labeling/Posting Requirements

 

 

1.0          Purpose

 

Jefferson Lab recognizes that lasers and their associated apparatus are inherently dangerous.  It is therefore required that they, and the designated area, be labeled to provide warning of the potential hazards.  This appendix defines Jefferson Lab’s labeling and posting requirements for equipment and areas; and how to update, repair, and maintain these labels.

 

2.0          Scope

 

These requirements apply to all Class 3 and 4 laser equipment and designated areas. 

 

The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6410 Laser Safety Program.

 

3.0          Responsibilities

NOTE:           Management authority may be delegated at the discretion of the responsible manager.

 

3.1            Qualified Laser Worker

·       Request an equipment/area hazard evaluation from the Laser Safety Officer if compliance with these requirements is unclear.

 

3.2            Laser Safety Officer (LSO)

·       Perform equipment/area hazard evaluation and provide labels as appropriate.

 

3.3            Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor

·       Ensure that warning labels are posted in accordance with requirements.

 

4.0          Process Steps

 

4.1            Equipment Labeling

 

4.1.1       Manufacturer’s Labels

Do not remove manufacturers’ equipment label.  Contact the LSO if labels are missing or damaged.  Read and follow manufacturer’s warnings.  Information includes:

·       certification label

·       aperture label

·       identification label

 

4.1.2       Original Equipment Manufacturer (OEM) or Custom Built Lasers/Systems

Follow American National Standards Institute (ANSI) labeling requirements and controls; or Center for Devices and Radiological Health (CDRH) requirements.  Contact LSO for evaluation and/or labeling requirements.

 

Equipment  labels must be positioned so they are readable and contain the following information:

  • Certification (i.e. meets CDRH requirements)
  • Identification
  • Name and address of manufacturer
  • Place, month, and year of manufacturer
  • Hazard Classification
  • Radiation output (power and wavelength) and warning logotype

 

4.2            Area Posting Requirements

 

4.2.1       Class 3B, Class 3R, and Class 4 Laser Areas – require a red danger signal word box ANSI DANGER sign.

4.2.3       During Times of Service/Alignment

During times of service and other times when a temporary laser-controlled area is established, an ANSI NOTICE sign is required.  This sign is posted only during the time when service is in progress.

 

Typical/Example

4.3            Update, Repair, or Maintenance to Labels 

Anyone at Jefferson Lab may request new, update, repair, or maintenance to a laser hazard label.

 

·       Contact the LSO and state the label needing review.

o   If it is determined that the label is defective, the LSO will rectify the situation.

o   If no hazard is found – the LSO informs the concerned party(s) of the determination.
