Details on protective eyewear can be found in AS/NZS 1337.4 and AS/NZS 1337.5.

The main form of PPE is protective eyewear, but in the case of class 4 lasers should also include protective clothing and footwear. To aid in managing the risk associated with the use of lasers, the following controls are to be implemented where lasers are used:

These engineering control measures incorporated into the design of the laser system may include: Lasers require certain built-in safety features dependent on their classification. The control measures and the associated requirements of all laser classifications are listed in detail in AS/NZS IEC 60825.1:2011 Safety of laser products Part 1: Equipment classification and Requirements Engineering Controls As a general principle, engineered controls are preferred where appreciable hazards exist, although these may need to be supplemented by the use of appropriate eye protection. Laser hazards may be controlled by the use of engineered controls, administrative controls and personal protective equipment, either singly or in combination. In addition to laser radiation, there are additional hazards such as collateral radiation, electrical shock, fire, cryogenics, mechanical hazards, vapours and chemicals, which all need to be considered when completing a risk assessment

Skin is less at risk from damage caused by lasers, but exposure to lasers still need to be managed appropriately to minimise the potential for skin burns Appropriate controls are essential to prevent ocular damage Damage can occur from heating, photochemical reactions and explosive rupture. Different parts of the eyes are susceptible to different wavelengths. They may cause skin injuries and could also constitute a fire hazard.Įyes are the most susceptible to damage from lasers. More stringent controls are needed to prevent exposure than with lower power lasers.Īre high power devices capable of producing eye damage even from diffuse reflection. In addition, beam reflections may also be hazardous. Precautions are required to prevent both direct viewing and viewing with optical instrumentsĪre more hazardous because of either higher output or operation outside visible wavelengths. Additional hazard control measures take the form of cautionary signs or labelsĪre similar to Class 2 however viewing may be more hazardous if the user employs optics within the beamĮmit in the wavelength range 302.5 - 10 6nm and have the potential to cause damage to the eyes from intra-beam viewing but the risk is lower than for Class 3B lasers. However, their outputs are low enough where eye protection is afforded by the blinking reflex. NB Modifications can increase the class and subsequent hazard of a laser.Īre safe under most circumstances and are incapable of damaging the eyes or skin because of either engineered design or inherently low power outputĮmit in the wavelength range 302.5 - 4000nm and may be hazardous if optics are used in the beamĮmit in the visible wavelength range 400 - 700nm and have sufficient power output to cause damage to the eyes if viewed continuously.

Lasers are divided into seven classes according to accessible emission limits.

AS/NZS IEC 60825.1:2011 Safety of laser products Part 1: Equipment classification and Requirements and AS/NZS IEC 60825.14:2011 Safety of laser products Part 14: A user's guide are the principal documents for laser safety. While lasers vary greatly in power output, wavelength and purpose, the hazard potential for eyes and skin can be significant due to the concentrated energy density. Lasers are capable of producing intense, collimated beams of light at specific wavelengths (visible, ultra violet and infrared).
