Oxygen And Acetylene Safety Precautions Youtube Oxygen can be 99% pure and makes things burn really fast. acetylene cylinders – these cylinders have lower amounts of pressure in them, but can be quite dangerous because acetylene is a fuel and can easily ignite. as a safety measure, acetylene should never be released or used at a rate above 15 pounds per square inch (p.s.i.). Acetylene is a compound of hydrogen and carbon (c2h 2). produced when calcium carbide is mixed with water. needs only 10% mix of oxygen to ignite. it is an unstable gas, will violently decompose when in a pure state above 15 psi. auto ignition temperature is 763o 824o f.
Oxygen And Acetylene Safety Precautions 42 Off In this type of welding acetylene gas and oxygen are mixed in a torch to attain the high temperatures that are required for the welding process. this process like any other process has risks that should be managed. this article will highlight oxy acetylene welding cutting safety precautions. In addition to engineering safety controls, but there are also some basic practical rules that apply to acetylene use per ansi z49.1 2012 (safety in welding, cutting and allied processes): before connecting, oxygen cylinder valves should be “cracked” (opened slightly while standing aside and re closed) before connecting the regulator to. 1910.253 (c) (3) (i) manifolds shall be of substantial construction suitable for use with oxygen at a pressure of 250 psig (1.7 mpa). they shall have a minimum bursting pressure of 1,000 psig (6.8 mpa) and shall be protected by a safety relief device which will relieve at a maximum pressure of 500 psig (3.4 mpa). Fe transport, use and storage of acetylene cylindersintroductionacetylene gas is colourless. it is slightly lighter than air, ighly flammable and can generate an explosive atmosphere at con centrations above 2.3% in air. very little e. ergy is required to ignite an air oxygen acetylene mixtu. matches or cigarette lighters.

All situations: wear appropriate personal protective equipment (ppe) when handling acetylene, including safety glasses, gloves, and flame resistant clothing. store acetylene cylinders in an upright position and secure them to prevent them from falling over. keep them in a well ventilated area away from heat sources and combustible materials. Doc #oh&s 18.36.1 – safety for oxyacetylene welding rev date:06 03 2014 printed copies of this document are uncontrolled. contact with oxygen. • open cylinder valves correctly. open the valve on the acetylene cylinder no more than three fourths of a turn so it can be closed quickly in case of emergency. open the valve on the oxygen tank fully.
