Welding is not an easy job. Keeping yourself safe while welding requires a clear understanding of what could go wrong, and getting prepared for it. The potential risks consist of electric shocks, skin burns, injury to eyes and injuries related to inhalation of toxic fumes. So, it is a must to wear protective over clothes and devices such as helmets and shields while doing all kinds of welding operations.

Importance of helmets and shields
According to www.safetyandhealthmagazine.com, chances for eye injuries are very high during welding if proper protection is not involved. Welding produces extremely bright lights which even contain light belonging to the ultraviolet spectrum. So, one should never view the arc with naked eyes especially within 50 Ft. distance.
The intensity and specific spectrum of the light vary depending on the process of welding, the metals used, the arc length, the current used for welding, etc. Those workers like fitters and operators who work near to the welding arc has to be protected from arc radiation. Welder, who is the closest one to the light and sparks, must wear a helmet for the protection of his face and eyes.
The welding helmet is usually made up of an insulator fiber material. Most of the helmets come with a flexible headband which makes it easy to use by different persons irrespective of their head sizes. The color of the welding helmet is dull black which is purposely done to reduce the glare and reflection produced by the intensely bright light,
A welding helmet is designed in such a way that it fixes over your head and can be moved upward when you are not welding. The helmet leaves free both the hands of the welder hence making welding easy. There are lens holders in the helmets to tuck in the filter glass and the cover glass.
The special design of the lenses prevents eye damage and flash burns due to harmful rays. They are usually green brown or blue in color. The optical densities of filter glasses vary based on the light intensities they need to filter out.
A cover plate is an extra layer of protection and its purpose is to protect the filter glass from spatters produced while welding. The filter glass must be tempered as well to prevent easy breakage. Manufacturer name and the number indicating shade should be marked on it.
Other safety precautions
· Respirator or Welder’s Mask: Buy the one that is suitable for the type of welding you are doing.
· Keep the welding area tidy and frequently check for any signs of gas leaks.
· Ventilation: Welding areas should be properly ventilated because poor ventilation often causes plume poisoning.
· Storage: Store all flammable materials carefully in a flammable liquids locker.
· Fire protection: Extinguishers are a must in a welding area because the sparks created during the welding process may start a fire.
· Protective Clothing: to protect the whole body from molten metal and sparks.
So, take care of all these things while welding! Prevention is better than cure!
