Subpart: D – Occupational Health and Environmental Controls
OSHA Standard: 1926.54
Occurrence: Initially upon assignment.
Frequency: As equipment, conditions, or roles change.
Training Style: Hands on training, toolbox talk, classroom instruction.
Non-ionizing radiation is described as a series of energy waves composed of oscillating electric and magnetic fields traveling at the speed of light. Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). Lasers commonly operate in the UV, visible, and IR frequencies. Non-ionizing radiation is found in a wide range of occupational settings and can pose a considerable health risk to potentially exposed workers if not properly controlled. Level 1 type lasers are included with this standard, that includes survey equipment. Construction limits worker exposure to 10 mW/sq.cm.
The employer shall provide for the instruction of each laser equipment operator and instructor in accordance with the applicable manufacturer's recommendations. The instruction process shall inform the operator of various hazards associated with the use of the equipment and the necessary or recommended control measures for the elimination of hazards to personnel. Areas in which lasers are used shall be posted with standard laser warning placards. In addition to information from the manufacturer, the American National Standard ANSI Z136.1-1986 could be reviewed for training information.
Take part in training is assigned any type of NIR equipment. Ensure that the laser beam is not directed at employees. When it is raining or snowing, or when there is dust or fog in the air, the operation of laser systems shall be prohibited where practicable; in any event, employees shall be kept out of range of the area of source and target during such weather conditions.
NIR is a series of energy waves composed of oscillating electric and magnetic fields at the speed of light. The most common example of NIR on the jobsite is survey equipment. Only qualified and trained employees shall be assigned to install, adjust, and operate laser equipment. Proof of qualification of the laser equipment operator shall be available and in possession of the operator at all times.
