Tooling U Welding 2024 Exam with Complete Solutions (1)

Tooling U Welding 2024 Exam with Complete Solutions (1) Air-Supplied Respirator - Answer-A breathing device that consists of a full face mask with a hose that connects to a freestanding compressed air cylinder. Air-supplied respirators are used in confined spaces to maintain exposure levels. Alloying Element - Answer-An element that is intentionally added to a metal in order to change its properties. Manganese is a common alloying element in steel. American National Standards Insitute - Answer-ANSI. A private, non-profit organization that administers and coordinates voluntary standards and systems. ANSI helps set guidelines for personal protective equipment used in welding. American Society Of Testing And Materials - Answer-ASTM. An organization that writes and updates specifications for a broad range of materials. ASTM provides specifications for PPE standards for shoes and eyewear in welding. ANSI Z49.1 - Answer-A standards document published by the American National Standards Institute that covers welding PPE and other safety concerns. ANSI Z49.1 is titled 'Safety in Welding, Cutting, and Allied Processes.' Attendants - Answer-Someone trained in permit space entry and surface rescue who remains outside a confined space during entry. The authorized attendant monitors the safety of workers in the confined space. Automatic External Defibrillator - Answer-AED. A portable electronic device that can be used to treat cardiac arrhythmias by allowing the heart to reestablish an effective rhythm. An AED is often used in CPR training. Beryllium - Answer-A hard gray metal. Because it is highly toxic, work involving beryllium should be done with local exhaust ventilation and air-supplied respirators. Central Nervous System - Answer-Comprised of the brain, spinal cord, and complex nerve tissues. The central nervous system controls many different bodily activities and may be damaged by overexposure to some welding fumes. Combustible - Answer-Any substance that is capable of igniting and burning. Oxygen is a combustible used in welding. Compressed Gas - Answer-Any gas held under pressure in a gas cylinder. Gas under pressure may pose a physical hazard from explosion. Conductor - Answer-A material that allows for the flow of electricity. Conductors include metals such as copper and aluminum. Conference Of Governmental Industrial Hygienists - Answer-ACGIH. A member-based organization that recommends and reviews threshold limit values for chemicals used in the workplace. The ACGIH advances worker protection. Confined Space Entry Program - Answer-A written set of policies and procedures for entering permit-required spaces. OSHA requires every employer whose employees enter permit-required spaces to develop a written plan. Cylinder Cart - Answer-Also called a hand truck. A cart on wheels used for moving small, heavy objects. Electric Burns - Answer-An injury caused by the flow of electric current through tissue or bone. Electric burns can cause severe tissue damage. Electrically Charged - Answer-A way of describing a wire or device that has current flowing through it. Welders must observe all necessary safety precautions near electrically charged devices. Electrically Live - Answer-Carrying an electric charge. Electrically live components in a welding power source include the interior lead and conductor. Electrocution - Answer-To be killed or injured by electricity. Electrocution is a main cause of death or injury in welding.
