Author of Manufacture of Artillery Ammunition, United States Artillery Ammunition, United States Rifles and Machine Guns, Broaches and Broaching, Gas-Torch and Thermit Welding. FIRST EDITION THIRD IMPRESSION McGRAW-HILL BOOK COMPANY, INC. NEW YORK: 370 SEVENTH AVENUE LONDON: 6 & 8 BOUVERIE ST., E. C. 4 1921 COPYRIGHT, 1921, BY THE McGRAW-HILL BOOK COMPANY, INC. PRINTED IN THE UNITED STATES OF AMERICA PREFACE Few fields afford a greater opportunity for study to the mechanic, the student, or the engineer, than that of electric welding. Arc welding, with its practical, every-day, shop appli cations for repair and manufacture, is in some respects crowding closely into the field in which the gas-torch has seemed supreme. With the development of mechanical devices for the control of the arc, the range of application to production work has greatly increased. Resistance welding presents in its various branches some of the most interesting scientific and mechanical problems to be found anywhere. Spot-welding butt-welding line-welding all occupy a particular place in our manufacturing plants today, and new uses are being constantly found. In the gathering and arranging of the material used in this book, particular care has been taken to classify and place various subjects together as far as possible. This is not only convenient for reference purposes, but enables the reader to easily compare different makes and types of apparatus. In most cases, the name of the maker of each piece of apparatus is mentioned in the description in order to save the time of those seeking information. No time or pains have been spared in the endeavor to make this the most comprehensive book on electric welding equipment and practice, ever published. Every possible source of informa tion known to the long-experienced editor has been drawn upon and properly credited. It is hoped that this book will prove a permanent record of electric welding as it is today, and also be an inspiration and source of information for those engaged in practice, research or development.

How to Treat a Sunburn – Sunburn Treatment

A sunburn is a radiation burn to the skin produced by overexposure to ultraviolet (UV) light, commonly from the sun”s rays. A similar burn can be produced by overexposure to other sources of UV, such as tanning lamps and welding arcs. Exposure of the skin to lesser amounts of UV will often produce a suntan. Sunburn.

Most sunburns can be treated at home. If you notice yourself, friend, or family member beginning to burn, immediately get out of the sun. If this is not possible, move to a shady spot and apply sunscreen. Also, cover exposed areas to keep from further irritation.

Relief can also come from anti-inflammatories and pain relievers like aspirin and ibuprofen. Placing cool compresses on skin can relieve pain. Taking a cool, but not cold, bath can also help sunburned skin. Avoid bath salts, perfumes, or oils because they can further irritate your skin. Using an aloe vera gel or lotion, or other drugstore treatment can help relieve skin. Do not apply butter or oil to sunburns.

Until the sunburn has healed, stay out of the sun and drink plenty of water to stay hydrated. Dehydration is frequently a by-product of a sunburn. Avoid drinking alcohol because it can dehydrate skin further.

Use a sunburn Over-The-Counter remedy containing aloe vera. Use a light moisturizer or a dusting of powder to relieve chafing. Avoid perfumes or scented items. * Use Over-the-counter analgesics to relieve the pain and headache and reduce the fever.

Use an OTC topical steroid cream such as Cortaid if the pain persists. Don’t use local anesthetic creams or sprays that numb pain such as Benzocaine. They can cause allergic reactions in some people.

Rest in a comfortable position, in a cool, quiet room. Stay out of the sun.

Chemical sunscreens

Chemical sunscreens absorb the harmful ultraviolet light to protect the skin against sunburn. Because different chemicals have varying effects on UVA and UVB protection, a combination of chemicals is usually used in sunscreens. Chemical sunscreens should be applied at least 15 minutes before sun exposure, to make the chemicals — cinnamates, octocrylene and the less commonly used para-aminobenzoic acid (PABA) and derivatives — more active on the skin.

Physical sunscreens

Physical sunscreens deflect UV radiation from the skin rather than absorb it. Zinc oxide or titanium dioxide are particularly effective, especially for the nose and ears. The spectrum of titanium dioxide protection extends into the UVA range and so it is often included in combinations with chemical sunscreens.

Drink plenty of fluids to replace the water lost through sweating in the sun, and to cool down. Do not drink alcohol because it will dehydrate you further.

For mild sunburn, apply a moisturising lotion or a special aftersun cream from a pharmacy. Aftersun helps to cool the skin as well as moisturising and relieving the feeling of tightness. Calamine lotion can also be used to relieve itching and soreness.

For adults, painkillers such as paracetamol or ibuprofen can help relieve pain and reduce swelling.
