He then screwed up the union again and turned on the cylinder valve. The moment he turned on the cylinder, there was an explosion in the regulator followed by fire. A jet of flame emerged from the back of the regulator and continued until the cylinder valve was shut off. A large portion of the regulator melted and burned during the incident. There was no injury to anyone. The welder going easy remained alert to save himself. An examination of the regulator revealed that there was some grease in the ball bearing in the front housing. The explosion actually occurred in the rear high- pressure section and the grease was found in the front housing of the regulator. It is concluded from both the above findings that: 0 An inexperienced person had overhauled the regulator. 0 There had been, in all probability, grease in the rear section too.
0 Each Case let carries 20 marks. 0 Detailed information should form the part of your answer (Word limit 150-200 rods). Case let 1 Oxygen Cylinder- short a potential Explosion hazard In an open area outside a mechanical workshop, a welder was cutting some steel plates with an ox-acetylene gas cutter. The oxygen cylinder was about to get empty so, he decided to replace it with a filled one. He unscrewed the regulator from the empty cylinder and installed it on the new full cylinder. When he opened up the cylinder valve, he noticed a leak at the union connection between the cylinder and the regulator. He therefore turned off the cylinder valve, unscrewed the union and examined the gasket. He found that there were two gaskets instead of one, which ought to be the case. So, he removed one of the gaskets.

Fgs edit The main objectives of the fire and gas system are to protect personnel, environment, and plant (including equipment and structures). The fgs shall achieve these objectives by: Detecting at an early stage, the presence of flammable gas, detecting at an early stage, the liquid spill (lpg and lng detecting incipient fire and the presence of fire, providing automatic and/or facilities for manual activation of the. 3 due to closing esd valves in a process, there may be some trapped flammable fluids, and these must be released in order to avoid any undesired consequences (such as pressure increase in vessels and piping ). For this, emergency depressurization (EDP) systems are used in conjunction with the esd systems to release (to a safe location and in a safe manner) such trapped fluids. Pressure safety valves edit Pressure safety valves or psvs are usually used as a final safety solution when all previous systems fail to prevent any further pressure accumulation and protect vessels from rupture due to overpressure by their designed action.

These systems may also be redefined in terms of esd/edp levels as: esd level 1: In charge of general plant area for shutdown, can activate esd level 2 if necessary. This level can only be activated from main control room in the process industrial plants. Esd level 2: This level shuts down and isolates individual esd zones and activates if necessary edp. Esd level 3: provides "liquid inventory containment". Sss edit The safety shutdown system (SSS) shall shut down the facilities to a safe state in case of an emergency situation, thus protecting personnel, the environment and the asset. The safety shutdown system shall manage all inputs and outputs relative to emergency shutdown (ESD) functions (environment and personnel resumes protection). This system might also be fed by signals from the main fire and gas system.
Process control and safety systems are usually merged under one system, called. Integrated Control and Safety system (icss). Industrial safety systems typically use dedicated systems that are. Sil 2 certified at minimum; whereas control systems can start with. Sil applies to both hardware and software requirements such as cards, processors redundancy and voting functions. Contents, there are 2 main types of industrial safety systems in process industry: 1, process Safety system or Process Shutdown System, (PSS). Safety Shutdown System (sss this includes Emergency Shutdown-(ESD) and Emergency depressurization-(EDP) Systems. A third system also exists which acts as a barrier and contains the spray out of hot oil gases from flanges, valves pipe power joints. These systems are popularly known as safety spray shields and flange e use of spray guards is mandated by osha.
1996 susanne gayle harris, special to the times. Hollywood filmmakers scored a regulatory victory when a bill to exempt movie set construction from Cal/osha permitting requirements unanimously passed the legislature. The bill, sb 987, approved late Thursday, would resolve a heated debate between the entertainment industry and state labor officials over whether or not sets can be constructed safely without requiring the same "activity" permits that protect workers in the construction industry. From wikipedia, the free encyclopedia, jump to navigation, jump to search. An industrial safety system is a countermeasure crucial in any hazardous plants such as oil and gas plants and nuclear plants. They are used to protect human, industrial plant, and the environment in case of the process going beyond the allowed control margins. As the name suggests, these systems are not intended for controlling the process itself but rather protection. Process control is performed by means of process control systems (PCS) and is interlocked by the safety systems so that immediate actions are taken should the process control systems fail.
Officials with the essay food and Drug Administration, which previously tried to restrict ephedra use, said they had attributed 17 reports of serious side effects to the herb.
