Title:

Non-ionizing Radiation Safety

Publication date:

8/11/2020

Effective date:

8/11/2020

BRIEF

Policy Summary

The Berkeley Lab Non-ionizing Radiation (NIR) Program is designed to prevent staff exposure to NIR in excess of the permissible exposures/Threshold Limit Values (TLV) for the human eye or skin and to ensure a safe working environment. The NIR Program at Berkeley Lab ensures personnel are protected from NIR exposure hazards including:

  • Magnetic fields.
  • Radio frequency (RF) and microwave radiation.
  • Artificial ultraviolet radiation (UV).
  • Visible light.

Note: Laser and acoustic (noise) safety are covered in separate RPM Laser Safety and Noise Hazard policies.

Who Should Read This Policy

Berkeley Lab employees, casual and participating visitors, affiliates, and subcontractors who could be performing work in or around NIR sources with the potential for an overexposure

POLICY

A. Purpose

The Berkeley Lab Non-ionizing Radiation (NIR) Program is designed to prevent staff exposure to NIR in excess of the permissible exposures/Threshold Limit Values (TLV) for the human eye or skin and to ensure a safe working environment. The NIR Program at Berkeley Lab ensures personnel are protected from NIR exposure hazards including:

  • Magnetic fields.
  • Radio frequency (RF) and microwave radiation.
  • Artificial ultraviolet radiation (UV).
  • Visible light.

Note: Laser and acoustic (noise) safety are covered in separate RPM Laser Safety and Noise Hazard policies, respectively.

B. Persons Affected

Berkeley Lab employees, casual and participating visitors, affiliates, and subcontractors who could be performing work in or around NIR sources with the potential for an over exposure.

C. Exceptions

None

D. Policy Statement

  1. Exposures to NIR must be maintained below the limits specified in Threshold Limit Values for Chemical Substances and Physical Agents, American Conference of Governmental Industrial Hygienists (ACGIH), 2016 edition (http://www.lbl.gov/ehs/pub3000/CH43.html#_Work_Process_B.Work Process B).
  2. Additional information and requirements for lasers are provided in the ES&H Manual, Chapter 16, Laser Safety.
  3. Exposures to NIR must be limited by engineering controls where feasible, followed by administrative controls and personal protective equipment.
  4. Access must be limited to only authorized personnel whenever the whole body could enter magnetic field strength exceeding 5 Gauss. Delineating the 5 Gauss line and posting magnetic field warning signs are generally acceptable access control (Work Process C).
  5. Environment/Health/Safety (EHS) assistance on NIR may be obtained by contacting the EHS NIR safety coordinator, ext. 2544 (Work Process D).

E. Roles and Responsibilities

Role

Responsibilities

Division Director

Ensures the NIR Program is enforced.

Environment/Health/ Safety (EHS) Division
  • Arranges or performs NIR assessment as requested or determined by an approved activity within the Work Planning & Control (WPC) system or other authorization method.
  • Provides guidance and establishes controls for NIR hazards.
  • Maintains the Berkeley Lab NIR Program.
  • Develops and reviews substitute or alternate control measures when primary measures are infeasible or impractical.
  • With the Activity Lead, investigates all instances of suspected exposure.

Supervisor/Activity Lead
  • Ensures that all NIR users receive adequate and appropriate training.
  • Ensures that all NIR users are assigned to a WPC activity.
  • Prepares an activity in WPC for an NIR operation and ensures that the provisions of the activity are properly implemented and diligently followed by users. (To complete an activity, go to Berkeley Lab's WPC portal.)
  • Ensures that any visitor receives a site-hazard orientation as part of any visit to any NIR area.
  • Investigates all instances of suspected exposure.

NIR Equipment User
  • Receives appropriate on-the-job training prior to unsupervised NIR equipment use.
  • Reads, understands, signs, and follows all procedures in the WPC activity.
  • Stops unsafe work activities (see the Stop Work Policy).
  • Works in a safe manner following Laboratory policy and procedural requirements.
  • Promptly reports any malfunctions, problems, accidents, or injuries that may have an impact on safety.
  • Immediately reports any suspected NIR exposures to the supervisor and EHS.
  • Refers any questions or concerns to the NIR Subject Matter Expert.

F. Definitions/Acronyms

Term

Definition

Non-ionizing Radiation (NIR)

Non-ionizing radiation (NIR) refers to electromagnetic radiation with insufficient energy to release a bound electron from an atom. NIR includes the following categories of radiation: ultraviolet (UV), visible light, infrared, radio frequency, microwave, and magnetic fields.

RF

Radio frequency — a portion of the electromagnetic spectrum from 3 Hz–330 GHz

UV

Ultraviolet radiation (180–399 nm)

G. Recordkeeping Requirements

Records are kept by the Laser Safety Officer for all magnetic field, RF, and UV surveys.
