Equipment operative protection

Introduction Review and audit processes are used in the chemical process industry to evaluate, examine, and verify the design of process equipment, operating procedures, and management systems. These processes assure compliance with company standards and guidelines as well as government regulations. Reviews and audits can encompass the areas of process and personnel safety, environmental and industrial hygiene protection, quality assurance, maintenance procedures, and so on. [Pg.2283]

Explosion Isolation For all equipment systems protected by design safety measures it is also necessary to prevent the propagation of an explosion from these protected vessels into operating areas or equipment connectedviainterconnectingpipeline. Such an approach is referred to as explosion isolation. [Pg.2330]

The fuse is a level detector and is both the sensor and the interrupting device. It is installed in series with the equipment being protected, and it operates by nieltiiig a fusible eleliieiit in response to the current flow. [Pg.420]

Safety Valve Required to Prelect Reducing Station Discharge Pressure in Cose of Valve Failure. SV-I is Set at Slightly Above Downstream Pressure of Reducing Station,and Protects All Equipment Operating at this Pressure on Steam Header. [Pg.429]

Tests carried out on protection systems comprise factory tests, on-site commissioning tests and maintenance checks. Those made on individual relays will demonstrate the compliance of the equipment with specification and the verification of its operation under simulated conditions, while tests carried out on-site prior to the equipment being put into service ensure that the full protection scheme and associated equipment operate correctly. These on-site tests must be comprehensive and should include ... [Pg.217]

The resistance of the system to earth must be low enough to ensure that earth fault protection equipment operates correctly. [Pg.227]

The significance of corrosion protection has risen sharply in recent years for a number of reasons (1) because of efforts to reduce the metal content of parts (e.g., by using thinner metallic support structures) (2) with the use of new types of equipment and processes involving expensive equipment operated under extreme conditions, such as nuclear reactors and jet and rocket engines and (3) in connection with the development of products having extremely thin metal films, such as printed circuit boards and integrated circuits. [Pg.379]

OTHER PROTECTIVE EQUIPMENT Full protective clothing will consist of M9 mask and hood, butyl rubber suit (M3), M2A1 butyl boots, M3 and M4 gloves, unimpregnated underwear, or demilitarization protective ensemble (DPE). For laboratory operations, wear lab coats and have a protective mask readily available. [Pg.443]

Portable fire water monitors and foam monitors give the fire suppression team the flexibility to set up the equipment in a location that provides maximum coverage of the water or foam spray with limited exposure to the fire personnel. Portable monitors can be set in place, with the stream on the equipment being protected, and fire personnel do not have to constantly monitor the operation. [Pg.226]

Area samples may occasionally be deployed in locations requiring protection from weather and dirt contamination. In a recent study of heavy equipment operators exposure to diesel exhaust emission we had to support and protect instrumentation systems upon heavy earth moving equipment. Exposure to mechanical... [Pg.462]

Inspection and observation of the work environment enables the auditor to help local management identify work hazards resulting from unsafe design, lack of protective features, or exposure to materials in or evolving from the process. It also provides an opportunity to observe work practices and equipment operations. [Pg.312]

Where corrosive conditions do exist, equipment is protected in sulfuric acid units by the use of stainless steel and in hydrofluoric acid units by the use of Monel. Both acids build up a thin layer of iron salt on carbon steel even in the cold. Such a layer of salt causes any moving parts to stick in time, and, therefore, most valves and pumps are protected with alloy trim under normal conditions and are solid alloy under severe conditions. Both types of units will have very little corrosion if properly designed and operated. [Pg.193]

Similar to installation rules, national standards for explosion protection in the presence of combustible dusts were established long before international standards. In Germany, VDE 0165/1991-092 (and this standard referring in parts to VDE 0170/0171 Teil 13/1986-11) defines requirements for electrical equipment operating in areas hazardous due to combustible dusts. [Pg.45]

Further safety precautions for the operation of photochemical equipment include protection against electrocution risks and efficient ventilation to prevent ozone exposure. Certain lamps may produce significant amounts of ozone de-... [Pg.75]

The lubricant in a joint or stopcock serves to protect the surface from wear, to prevent leakage, and to facilitate the separation and rotation of the two members. Petroleum jelly is used for many assemblies but is unsuitable for equipment operating at high temperature or under vacuum. Some laboratories prepare special greases for use under conditions that do not permit hydrocarbons to be used. [Pg.105]

Mechanical failure or abnormal operation of machinery or equipment might cause such explosible or ignitable mixtures to be produced and might also provide a source of ignition through simultaneous failure of electrical equipment, operation of protection devices, or other causes. [Pg.792]
