If you work with laser, you must have complete knowledge about the use and handling of the laser. Everybody who deals with laser agree with the following guideline. The first and the foremost thing about the laser is that you must be aware of its effects and risk .The more you will be associated with the laser, you will learn more about it. While experimenting, all the experimentalist become quite se cure as the experiment is carried on an optical table. During this experiment all the laser rays pass in a horizontal plane and they stopped at the edge of the optical table. The entire experimentalist should not put their eyes on the horizontal plane of the table. If the persons involved in the experiment follow this guideline, he will be able to reduce the risk. But one should remember that the risk is not totally avoided.

The other guidelines that one should follow are to keep mirrors and lenses in a vertical position. The operator must remember that accidentally upward reflection may cause damage to the eyesight. While doing some experiment if one wants to pick up anything from the floor, he should close his eyes. This may give some protection, but not sufficient. Therefore guidelines regarding laser use may not be safe enough. Therefore it is advised to all the lesser operators to use eye protection.

As the most reliable protection, it is always advised that all the operators must use adequate protection. The operators must be extra cautious about the ultraviolet beams, which if directly fall on the skin may cause skin cancer. The operator must careful about optical elements including mirrors and their position. It is because the beams may strike and reflect and thereby may cause serious problem. The operators of the blue laser pointer must take adequate eye protection against laser beams and this become highly essential when he works with multiple wavelengths. If an operator follows these guidelines, the risk is reduced a little, but there is no guarantee that he is quite safe. Actually, the operator should understand the nature of his work and accordingly he should take protection.
