■ Summary of Manufacturer’s Requirements
*With respect to the requirements of remote interlock connector, key control, emission warning and attenuator, Class 3B laser products not
exceeding five times the AEL of Class 2 in the wavelength range of 400 nm to 700 nm are to be treated as Class 3A laser products.
Note: 1. This table is intended to provide a convenient summary of requirements. See text of this standard for complete requirements.
2. AEL: Accessible Emission Limit
The maximum accessible emission level permitted within a particular class.
For your reference, see ANSI Z136.1-1993, Section 2.

hazardous
Protective housing Required for each laser product; limits access necessary for performance of functions of the products
Safety interlock in pro-
tective housing
Designed to prevent removal of the panel until accessible emission values are below the AEL (See Note 2) for
the class assigned
Remote control Not required Permits easy addition of external interlock in
laser installation
Key control Not required Laser inoperative when key is removed
Emission warning de-
vice
Not required Gives audible or visible warning when laser
is switched on or if capacitor bank of pulsed
laser is being charged
Attenuator Not required Gives means beside ON/OFF switch to tem-
porarily block beam
Location controls Not required Controls so located that there is no danger of exposure to AEL
above Classes 1 or 2 when adjustments are made.
Viewing optics Emission from all viewing systems must be below Class 1 AEL’s as applicable
Scanning Scan failure shall not cause product to exceed its classification
Class label Required wording Figures A and B and specified wording
Aperture label Not required Specified wording required
Service entry label Required as appropriate to the class of accessible radiation
Override interlock label Required under certain conditions as appropriate to the class of laser used
User information Operation manuals must contain instructions for safe use
Purchasing and service
information
Promotion brochures must reproduce classification labels; service manuals must contain safety information
Medical products Special calibration instructions required Special calibration instructions, means for
measurement and target-indicator required
Fibre optic Cable service connections require tool to disconnect if disconnection breaks protective housing and permits ac-
cess above Class 1
