This document provides guidelines for safely working on gas lines. It describes the necessary precautions that must be taken which include ensuring there are no power lines or leaky gas lines nearby, using non-sparking tools, having adequate lighting and emergency equipment, and monitoring gas levels with detectors. The document also outlines do's and don'ts for gas cylinder handling and storage such as not dragging cylinders and prohibiting smoking around oxidizers or flammables. Overall, the document aims to establish minimum safety requirements for any work involving gas lines.

Objective of this Standard is to describe the recommended basic safety requirements for working on gas line . It describes briefly the precautions to be taken, safety appliances to be available and their use in gas lines. This standard establishes the minimum requirement and guidelines for the safe operation while working on gas lines.
State of matter in which material has a very low density and viscosity. In respect to fire & explosion hazards, gases may be ranked in combustible and non- combustible gases. Combustible gases are those that burn in air with normal oxygen concentration. Non combustible gases are those that do not burn either in oxygen or in air. A portion of these gases support combustion (e.g., oxygen),while the other portion inhibit burning are called inert gases(e.g., nitrogen, carbon dioxide ,Nobel gases).
Industrial gases are used in a wide range of industries, which include oil & Gas, power, mining, steelmaking, medicine and many more. So , Industrial gas is supplying through tanker, pipeline down to cylinder vessel. Flammability limit Flammable Limits, also known as the flammable range: percentage of gas within the LEL and UEL where combustion may occur and be sustained.
Effect of Carbon Monoxide on respiratory system :- The carbon monoxide when breath in along with air is absorbed by the blood and deprives the blood of its oxygen carrying capacity and forms carboxyl haemoglobin in place of oxyHemoglobin. Haemoglobin has 200 to 300 times more affinity for carbon monoxide than oxygen. The body tissues suffer from Anoximia (lack of oxygen). Symptoms of gas exposure: Headache, Nausea, Vomiting, Feeling of giddiness, difficulty in breathing
It needs presence of ignition source in the vicinity from gas cutting welding spatters, electrical sparking, sparking from tools and tackles, or thunder etc. Standard practices to be taken for hot work in gas line. Prevention:- Before commencing and/or executing any work in and around the gas line one should ensure: a) There should not be any naked power cabling near gas lines. b) No leaky flammable gas lines nearby. Inform the owner of the gas lines if any leakage is found from the pipe, fittings or flanges. Start the job only after the gas line owner attends the leakage. c) The tools and tackles to be used for gas line maintenance are non-sparking non-ferrous material.
Prevention: Make a safe approach to working points by scaffolding. Keep calibrated gas detector with each working group. Use Gas Mask if CO PPM is more than 50 PPM . Make adequate area illumination arrangement if job is to be continued after day light or in night . Barricade the working area as well as the crane swing area. A display board with emergency contact numbers (such as Fire Brigade, First Aid, Gas Safety, Energy centre, Job In-charge working agency etc.) should be kept at the site. Make rain protection arrangement at the working point if the job is to done in the rainy season or the weather is cloudy and it is likely to be rained. Artificial respirators and gas mask to be kept at site . First aid &fire fighting arrangement (water, sand, and clay) should be there and people should know how to use it.

Drag or slide cylinders, even for short distances. Use cylinders as rollers for moving material or other equipment. Permit oil, grease, or other readily combustible substances to come in contact with cylinders, valves, or other equipment in oxidizer service. Remove any product labels or shipping hazard labels. Lift a cylinder by its cap using a sling or a magnet. Attempt to catch a falling cylinder Allow storage temperature to exceed 125属F (52属C). Permit smoking or open flames in oxidizer or flammable gas storage areas. Expose cylinders to corrosive materials such as ice melting compounds. Use oxygen as a substitute for compressed air.
