1 FOREWORD The ”Occupational Safety and Health Act of 1970” (OSHA) was enacted ”to assure safe and healthful working conditions for working men and women...”.  As duties under Section 5 of this Act, each employer shall: 1.   Furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees. 2.   Comply with occupational safety and health standards promulgated under this act. Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct. If an employee has language difficulties or cannot be expected to read and understand this booklet, the employer should provide additional training and help to the individual. This booklet provides safety and health information on oxy-fuel gas welding, cutting, heating, and allied products and processes such as brazing, soldering, and use of air-fuel gas equipment. You should be familiar with the information in this booklet as well as ”Safety in Welding and Cutting” – ANSI Z49.1, which is published by the American Welding Society, P. O. Box 351040, Miami, Florida, 33135. Material Safety Data Sheets (MSDS’s) on various products, such as welding rods, wires and fluxes, also provide helpful safety and health information. Read the manufacturers’ operating instructions for the apparatus you use. You should be familiar with the proper operation of all equipment before you start to work. ALWAYS READ AND UNDERSTAND THE MANUFACTURER’S OPERATING INSTRUCTIONS AND YOUR EMPLOYER’S SAFETY PRACTICES BEFORE OPERATING AND MAINTAINING GAS WELDING AND CUTTING EQUIPMENT. – Also – ALWAYS READ AND UNDERSTAND ALL PRECAUTIONARY LABELS AND INSTRUCTIONS BEFORE USING EQUIPMENT, MATERIALS, OR GASES. A typical precautionary label (tag) for welding materials is shown on page 3. This booklet provides supplementary precautionary information.
