( 1 ) material; ( 2 ) P&ID diagram; ( 3 ) A division map of the hazard level of electrical equipment; ( 4 ) Foundation of design and design of pressure relief system; ( 5 ) Ventilation system design drawings; ( 6 ) Design standards or specifications; ( 7 ) Material balance sheet and energy balance sheet; ( 8 ) Measurement control system; ( 9 ) Safety systems (such as interlocking, monitoring or suppression systems). Table device security information name and content Device security information name Device security information content Structural material It can be noted either in the equipment folder or in the piping specification on the piping diagram. P&ID diagram The problematic part must be updated from time to time; The holder must be specified, usually the producer; Determine the storage location of the official version of the drawing, usually stored in the drawing frame of the main control room; When necessary, or if the project belongs to a classification area, the drawings should be updated at any time based on the progress of the project. Divide electrical grades as required For example, China adopts explosive environment Part 1 : General requirements for equipment ( GB 3836.1 ), the United States adopts National Electrical Code ( NEC ), and Europe adopts Explosion Protection Directive ( ATEX ); Marked on the plan view and top view; Mark the specific area with different hatching. Ventilation system design specification heat transfer drawings can be found in the equipment documentation and / or piping instrumentation diagram Control room: booster, air inlet detector, automatic shut down, etc.; Process plant: the relationship between ventilation and pollutant emission rate; Steam / dust / smoke area control: a nose-like exhausting device. Material and energy balance Using process simulation software to simulate the process, the calculation result of material and energy balance is obtained; For mass production processes, the corresponding “recipe†should be established. Monitoring and control system file management Limited to functional safety as identified in process hazard analysis such as process interlocks / alarms; Most basic process control systems have no significant impact on process safety; Most quality control, P&ID control and sequence control; Require attention to equipment that will cause different process safety incidents; Including all metering control systems, these devices are directly related to process safety. ( 1 ) Obtain information on the main equipment from the equipment supplier, including equipment manuals or drawings, maintenance and operation guides, and information on troubleshooting; ( 2 ) Obtain relevant information from documents and materials such as mechanical completion report, stand-alone and system commissioning report, supervision report, special equipment inspection report, fire inspection report.
