1 Common gas related hazards Gas can be supplied from the mains supply or a storage tank It can also be supplied from smaller portable cylinders used close to the work site Types of gas commonly used in the workplace include natural gas liquefied petroleum gas LPG LPG autogas LPGA medical gases methane VISION ® T5 Every feature of the Vision T5 CNC is designed to simplify machine operation for the most productive cutting results An Operating Wizard helps new users get started in minutes with clear step by step instructions and prompts In the first four months of the year China’s domestic gas output climbed 10 3 percent to 64 4 bcm while imports of combined pipeline gas and LNG rose just 1 5 percent from a year earlier to 32 Not just gas cutting any sort of welding deserves taking the maximum precautions Gas welding involves a lot of sparks and spatters You should wear good quality protective clothing gear Consider having a leather welding jacket for this purpose Ship breaking also known as ship demolition ship dismantling ship cracking or ship recycling is a type of ship disposal involving the breaking up of ships for either a source of parts which can be sold for re use or for the extraction of raw materials chiefly scrap Modern ships have a lifespan of 25 to 30 years before corrosion metal Oct 20 SAFETY IN GAS CUTTING Maroon in color Acetylene gas C2H2 is dissolved in acetone liquid and stored at psi in a specially designed cylinder Acetylene cylinders have a volume of 8 5 m3 Acetylene cylinder pressure between 7 Kg/cm2 PSI to 3 kg/cm2 PSI GCE Cutting and Welding Technologies GCE CWT is one of the global market leaders in gas welding oxy fuel cutting brazing and heating processes GCE CWT provides a full range of gas pressure regulators arc welding gas economizers safety equipment and a comprehensive global range of torches specially designed to meetOSHA Compliance The following is based upon Federal Regulations Standards 29 CFR part safety and health regulations for construction subpart J welding and cutting Any individual engaged in welding and cutting must demonstrate compliance with these provisions Transporting moving and storing compressed gas cylinders A fire at a gas company& 39 s acetylene cylinder filling facility was put out and massive gas blasts narrowly avoided in Wuxi City of east China& 39 s Jiangsu Provin
