Anyone seen this weeks Westmorland Gazette?
No lesser person than Steve Callaghan himself has deemed to answer a readers concerns over the use of lasers, and their possible harmful effects if shone in ones eyes!!
The letter is well composed, and technically explicit and lacks many spelling or grammatical errors... I suspect Steve has been to night classes since his posts on the CSCP forums and here, or has invested in some sophisticated spell checking software!

No need for alarm over laser beams
Your reader’s letter regarding laser classification systems and the application to the lasers used in speed enforcement systems (Letters, December 1) may cause readers undue alarm. While Class 1 and Class 2 laser equipment were mentioned by your correspondent, the classes were not explained.
I can explain why there is no cause for concern over the use of laser light. Laser systems are classified by the International Electromechanical Commission Technical Committee standard IEC 60825-1 adopted in Europe as EN 60825-1. Class 1 and 2 laser systems, more correctly class 1, 1M, 2 and 2M, are laser systems that are classified as being safe to use and are allowed to be sold to the general public. The products so classified require no training to be given in their use.
Class 1 products are often referred to as ‘eye safe’ laser products with the power and risk to health so low that children’s toys are allowed to be in this class. Class 2 lasers use visible light and are classified safe as long as the viewer of the visible light averts their eyes with their natural reaction to bright lights.
The M in class 1 and 2 indicates that a hazard may result if the laser light is observed through a magnifying instrument such as binoculars but not spectacles. Typical examples of class 1 and 2 laser systems are laser printers, compact disk players, barcode scanners and laser pointers used in schools and colleges; these items are not, as far as I know, causing undue concern to the public or significant reportable incidents.
The laser in all of the speed enforcement equipment we use is classified as class 1, as is the product, and therefore presents no hazard according to the British Standards Institute and International Electromechanical Commission Technical Committees.
I hesitate to add that it is the same class as that of a child’s toy but do so to show that there is no concern for harm to health implied in the letter of December 1, even though it may cause some jocular retort.
It should come as no surprise that due consideration has been given by experts to assess, classify and render safe our operations. No heed should be paid, therefore, to the lay information expressed last week as it is erroneous.

Oh my goodness.... my school english lessons... it's all coming back to me!

That would CERTAINLY illicit a jocular retort!
Could somebody translate for Wildy just in case!
