If you are unsure of the proper eyewear requirements, do not operate the laser system with a Class 4 conversion module installed, contact your certified laser safety representative or contact the ALFA LASER factory support team at



The Laser Cleaning Machine is equipped with interlocked access doors on both sides of the unit. An optional Class 4 conversion module allows the user to operate the laser system with the side panel open. This device bypasses the safety interlock on the side panel of the laser system. When this optional device is installed, the protective system housing cannot completely contain the infrared laser radiation produced by the laser source, creating an exposure risk. This optional device redefines the safety classification of laser systems from Class 1, which is considered safe under all conditions of normal use, to Class 4, which is considered potentially hazardous. Additionally, the system enclosure does not contain flames or by-products from potentially ignitable materials within the system enclosure. Also be aware that infrared laser radiation emitted from the housing of a system with a Class 4 conversion module can damage or ignite combustible materials in immediate or distant locations.

There are several mandatory safety precautions defined by national and international laws and standards that must be observed when operating a Class 4 laser system. Specific safety measures are provided by the manufacturer through inclusion in an optional Class 4 conversion module, including: This feature can be used to connect an interlock switch to the door of a specific room where a laser system is operating, so that the laser is automatically disabled when the door is opened.

◉ Interlock Key Control - Removable key to prevent tampering with the laser.

◉ Laser Radiation Emission Warning signage – A visible warning light that indicates when a laser emits under operation.

◉ Attenuator – A mechanical device used to block the emission of laser radiation. The device is in the form of a manually operated shutter or Curtains.

◉ Class 4 Warning Label - A Class 4 warning label indicating that the laser system is classified as Class 4 and should only be always operated in a well-ventilated area. When installing the optional Class 4 conversion module, the laser system owner must observe operational safety precautions.


4. These safety instructions are required for operation of Class 4 laser systems under Canadian Federal & Provincial Law, US federal and state law in the United States and most foreign countries:


Many of these safety instructions comply with ANSI standards. Z136.1 US National Standard for Safe Use of Lasers, or equivalent standards available in most other countries such as B. European Standard EN 60825-1. Other safety measures may be mandated by state and/or local authorities, such as the German Employers' Liability Insurance Association's BGV B2 laser emission regulations, and it is the owner's responsibility to understand and comply with these laws. is the responsibility of Here is a quick summary of the most common safety requirements for owners of Class 4 laser systems:

◉ In any facility wherein a Class four laser device is to be operated, a person needs to be certain as a Laser Safety Officer (LSO) who will count on the authority and duty to reveal and put into effect the manipulate of laser hazards. The LSO need to study in laser protection and be privy to all protection measures set through law. There are many avenues to gather this education. Recognized reasserts of this education are the Laser Institute of America, the Employer's Insurance Liability Associations in European countries, or laser protection institutions in the Owner's USA or territory.

◉ The Owner of a Class four laser device might be chargeable for the introduction of a managed vicinity wherein the Class four laser device might be operated. A managed vicinity is designed to absolutely incorporate the laser radiation that may get away from a Class four laser device, with measures in area to save you unauthorized employees from coming into the vicinity, such as lighted caution symptoms and symptoms outdoor the certain and managed vicinity and interlocks on entryways.

◉ The LSO might be chargeable for designating and education all employees legal to perform, hold, or carrier a Class four laser device. It can also be the duty of the LSO to take measures to tell and limitation all unauthorized employees from get right of entry to a Class four laser device.

◉ The Owner of a Class four laser device might be chargeable for figuring out and supplying to all legal employees any defensive gadget consisting of specially designed eyewear, defensive gadget, and apparel wished whilst running, maintaining, or servicing a Class four laser device. Furthermore, the Owner will make sure that no juveniles perform the laser. If the laser is in use, the consumer will even make sure that mirrors, lenses, and different reflecting substances are constant and are handiest moved in a managed manner.

◉ The LSO might be chargeable for often auditing all protection measures. This consists of normal retraining of legal employees, serialization, and normal inspection (and alternative whilst vital) of all unique eyewear and apparel, and normal inspection of all protection measures surrounding the managed vicinity wherein a Class four laser device is operated. The LSO can be required to hold information as vital to show compliance.

◉ The LSO might be chargeable for normal scientific surveillance of all legal employees running a Class four laser device. For example, this consists of however is not always confined to, obligatory annual eye exams.

◉ Class 4 laser structures need to know no longer be used at alternate suggests or exhibitions.

◉ Prolonged publicity to meditated mild from an excessive electricity IR (1064nm) laser can reason pores and skin burn.
