Consumer Laser Products
Michael Higlett is a Principal Radiation Protection Specialist at the UK Health Security Agency( UKHSA), specialising in the effects of non-ionising radiations.
Lasers are found in various consumer products, including laser pointers, DIY equipment, night lights and toys. As laser technology has advanced over the years, it has led to a decrease in cost while simultaneously making high-power laser products available that pose risks to the eyes, ranging from temporary visual impairment to permanent sight loss, as well as risks to the skin. The internet has created a marketplace for these high-power devices, potentially bypassing product safety regulations.
Laser classes with increasing risk
For over 15 years, the UKHSA and its predecessors have advised that consumer products containing Class 1 or Class 2 lasers are unlikely to cause eye or skin injuries. Class 1M, Class 2M, and Class 3R laser products may be acceptable for use by consumers if the manufacturer has assessed that the risk of eye injury is very low when used as intended.
In response to growing concerns, a new European standard for consumer laser products was adopted and published in the UK as BS EN 50689:2021. This specifies that only Class 1, Class 2 and a subgroup of Class 3R lasers can be used in consumer products. Laser products that are appealing to children must not exceed Class 1, while the highest two classes( Class 3B and Class 4) are not suitable for general use by consumers.
Selection of consumer laser products
The introduction of BS EN 50689:2021 was timely, given the increasing availability of high-power handheld lasers that pose a risk of injuries, not only near the product but also
Classification Laser products are classified according to BS EN 60825-1:2014 + A11:2021 based on the level of accessible emission. They are grouped into eight classes( Class 1- Class 4, plus subclasses)- the higher the class number, the greater the likelihood of causing harm. The risk also depends on the conditions of use, exposure time and the environment.
