Laser Safety
The fact that lasers utilise radiation technology does mean that some lasers can be dangerous. However, not all lasers pose any kind of significant threat to the general public and the myth that they can all burn the skin and damage your eyes is not always true.
So, for example, the type of laser technology used in a laser pointer that you might use to make a presentation is not generally harmful - these pointers have generally been approved for use in these situations. However, deliberately shining this kind of light into the eye for prolonged periods is not recommended as it can cause damage. And, in recent months there has been at least one incidence of a pilot experiencing problems by being blinded by a type of laser pointing device in the air.
The actual danger posed by any laser is usually indicated by a numbering classification system that ranges from Class I to Class 4. Class I lasers are generally the safest usually because they are not put in a position to harm - so the laser reader on a CD player would be classified as Class I, for example. However, the lasers used on a CD burner are more powerful so they would be set at a higher range usually. The highest and most dangerous classification, Class IV, is generally reserved for industrial strength lasers. These lasers could potentially cause burns and eye damage.
People who work with lasers in industrial applications may well find that they are expected to use some form of protective clothing to make sure that they do not suffer from any adverse effects. These include items such as goggles, glasses and protective clothes.
