FDA Monitoring of Children's Laser Pointer Safety

Laser is everywhere, it is also possible touched by children. 

Children are always seen as the newborn sun at eight or nine clock in the morning, which means that children are our hope, children are our future. Thus we should try our best to protect children to make sure they live in a safety and health condition. Children safety problem has always been paid close attention by the public. For it is well known that children are our future. In the children safety problem, children's toys security gets more and more attention. The plenty of children's toys accidents make everybody have recognition about it. Recently, FDA issued a draft guidance documents. The draft aims to tell public, children's advocates and children's toys manufacturers the attitude and policy of FDA in the treatment of children's safety. In the draft, the main aimed at the children safety is laser products safety issues. 

Laser is a high-tech product with inconceivable power. Laser safety standards are varying. Now federal law case specification stipulate that all laser products sold in the United States must com ply with federal performance standards of laser products. While FDA has no special regulation about children laser products. Recently FDA comes up with a motion to make meaning to the laser products for children and stipulate that the laser products must conform to the luminous limit of International Electro technical Commission Class 1. The FDA is still working for the rulemaking. The purpose of the rule is to courage manufacturers to follow the luminous limit of children laser products, for the sake of reducing the risk of laser toys. 

The draft refers to the toy designed, produced and promoted for the children under 14 years old. Such toys are equipped with laser, such as cap pistol with laser for collimation; the spinning top that can emit laser beam while turning; the handheld laser device like laser sword; the fixed cylinder that can emit jumped laser beam and also the entertainment laser with gorgeous optics effects. They are all the amazing laser products. FDA believe that the radiation quantity of laser must be inferior to the luminous limit of the federal laser products performance Class 1 or the level of International Electrotechnical Commission Class 1 , which set according to the operate, maintenance, service , disabled and damaged condition. Within these standards, the risk for the user is the lowest. The current standard has no special mention to laser, but laser is an important part, because it laser could hurt your eyesight.

Come so far, the cap doesn't stipulate that children laser toy must accompany with Class 1 label. While the opposite is, FDA encourages manufacturers to stick labels on products to make customers aware of the risk clearly. FDA indicates that unless the parts of toy with laser can be removed, as well as can emit laser alone, otherwise the whole toys shall be regarded as laser products. Relevant products must obtain product certificate. Children toy safety is waiting to be solved. Buying a safety laser pointer with FDA label is necessary. Well, please allow me to recommend you with www.highlasers.com. It is a professional and reliable laser devices supplier and all of the laser products sold from their company are all certificated by FDA, the most authoritative safety organization.

Regulate the application of laser pointer

Everyone wants and do get a laser pointer, because they can use it for play using. Point star, burn match, play with pet, speech instruction and so on. We are surprised by its power, the shining beam release from a small pen, the beam is bright and last long. Many naughty people use it for practical joke, they point to driver, bird, even plane. They don't aware how dangerous it might leads. Recently, FBI and FAA say that it should seriously punish the people who use a laser pen to point aircraft and disturb pilot. The picture above is taking when pilot disturbed by green laser pointer.

The insignificant tiny beam can release such a huge and shining spot. To the night fly, especially in the period of taking off and landing, a laser shoot can cause an unimaginable dangerous. In fact, the power of laser pointer has underestimated by most of the public. As the grading standard of laser safety class made by FDA, only Class 1 is safe to use, it's power is less than 1mW and don't need to labeled with warning mark. To more than 1mW laser pointer or other laser device, it is reserved to label with permanent warning mark.

I also have seen a video is a man use a laser device shoot to driver across road. The beam is so bright and shot far away that driver disrupted and lost his way. This is an experiment made by police to tell people do not play your laser pointer everywhere and without restrict. Common people hardly imagine why such a tiny pen can make such a hazard. If we see the laser light directly with our naked eye, even those low power laser pointers, it is still easily to cause temporary visual damage, including glare, flash blindness and afterimage. What will happen if it points to pilot?

In general, the spot we see in PPT screen or wall is only with 5~8mm diameter. So we don't believe what kind of dangerous can this tiny spot make. Please don't forget that light will spread after a long flight. When a laser pointer shoots a mile away, it can form a bow big strong halo. This halo is enough to illuminate the whole plane cockpit, in other words, it is enough to keep pilot feel dizzy and can't see the front runway, down lamp, as well as dashboard, the horizon. Can you imagine what will happen especially at the moment of landing and adjusting the angle. So far, although there is no laser pointer crash accidents caused by laser pointer, more and more laser pointer interfere with flight case appeared. Therefore, it is urgent to control and discipline this kind of behavior.

Laser Safety Class

Laser safety consists of the safe design, laser use and switch of lasers to minimize the risk of laser accidents, such as eye injuries, skin hurt, light pollution and so on. It all because that even a small amount of laser light can lead to permanent eye injuries. Here are the a survey summarizes the various medical conditions caused by lasers at different wavelengths. The wavelength between 180nm to 315nm can cause inflammation of the cornea, as the sunburn. The wavelength between 315nm to 400nm caused photochemical cataract. The range from 400nm to 780nm give rise of photochemical change to the retina, retinal burn. The wavelength from 780nm to 1400nm makes cataract,, retinal burn. The laser from 1.4μm to 3.0μm are less common, be used in military or industry, this range may leads aqueous flare. As the range from 3.0μm to 1mm, this kind of laser will cause corneal burn. The above describe is about the hurt to eye, the skin is usually much less sensitive to laser light than the eye, but the excessive laser shoot can also cause the tiny or serious effect, especially the infrared laser. 

Class I  Inherently safe. It is impossible of eye damage. This is usually applied in CD player or laser printers.

Class II  Output power may be up to 1mW. This class includes only lasers that emit visible light but the infrared laser. Most laser pointers are in this category.

Class IIa  A region in the low powered end of Class II. The laser belong to this class requires in excess of 1,000 seconds of continuous viewing to produce a burn to the retina.

Class IIIa  The lasers are mostly dangerous in combination with optical instruments which change the beam diameter or power density. The direct contact with the eye for over two minutes may cause serious damage to the retina. Output power does not exceed 5mW. Many laser sights in military are in this category.

Class IIIb  Lasers in this class may cause damage if the beam enters the eye directly. This generally applies to lasers powered from 5-500mW. It can give rise to permanent eye damage within a second.

Class IV  Lasers belong to this class with the power of more tham 500mW will cause severe, permanent damage to eye and skin. This kind of laser are widely used in military, science, industry, and medical cure.

The mark of the safety class are usually marked on the surface to help you choose a safety laser pointer. In case, you need to buy a relieved laser products such as laserpointer, laser sight, laser alignment or others, you can have a surf in Highlasers.com whose products are all marked safety mark on the surface.
