API RP 754 2010 pdf download.Process Safety Performance Indicators for the Refining and Petrochemical Industries.
1 Scope 1.1 General This recommended practice (RP) identifies leading and lagging process safety indicators useful for driving performance improvement. As a framework for measuring activity, status or performance, this document classifies process safety indicators into four tiers of leading and lagging indicators. Tiers 1 and 2 are suitable for nationwide public reporting and Tiers 3 and 4 are intended for internal use at individual sites. Guidance on methods for development and use of performance indicators is also provided. 1.2 Applicability 1 This RP was developed for the refining and petrochemical industries, but may also be applicable to other industries with operating systems and processes where loss of containment has the potential to cause harm. Applicability is not limited to those facilities covered by the OSHA Process Safety Management Standard, 29 CFR 1910.119 or similar national and international regulations. At colocated facilities (e.g. industrial park), this recommended practice applies individually to the companies that own and operate the processes and not to the site as a whole. Events associated with the following activities fall outside the scope of this RP and shall not be included in data collection or reporting efforts: a) releases from pipeline transfer operations occurring outside the process or storage facility fence line; b) marine transport operations, except when the vessel is connected to the process for the purposes of feedstock or product transfer; c) truck or rail operations, except when the truck or rail car is connected to the process for the purposes of feedstock or product transfer, or if the truck or rail car is being used for on site storage; d) vacuum truck operations, except on-site truck loading or discharging operations, or use of the vacuum truck transfer pump; e) routine emissions that are allowable under permit or regulation; f) office, shop and warehouse building events (e.g. office fires, spills, personnel injury or illness, etc.);

[1 3] 3 Terms, Definitions, Acronyms, and Abbreviations 3.1 Terms and Definitions For the purposes of this recommended practice, the following definitions apply. 3.1.1 acids/bases, moderate Substances with pH ≥ 1 and < 2, or pH > 11 .5 and ≤ 1 2.5, or more precisely, substances that cause full thickness destruction of intact skin tissue within an observation period up to 1 4 days starting after the exposure time of 60 minutes or less, but greater than three minutes, consistent with Globally Harmonized System of Classification and Labeling of Chemicals (GHS) Skin Corrosion Category 1B. [11 ] 3.1.2 acids/bases, strong Substances with pH < 1 or > 1 2.5, or more precisely, substances that cause full thickness destruction of intact skin tissue within an observation period up to 60 minutes starting after the exposure time of three minutes or less, consistent with GHS Skin Corrosion Category 1 A.  3.1.3 Company When designated with a capital C or “the Company”, refers to the operating Company in the refining and petrochemical industries, its divisions, or its consolidated affiliates.
3.1.6 contractor and subcontractor Any individual not on the Company payroll, whose exposure hours, injuries, and illnesses occur on site. 3.1.7 days away from work injury Work-related injuries that result in the employee being away from work for at least one calendar day after the day of the injury as determined by a physician or other licensed health professional. This is an abridged version of the definition used to report days away from work injuries for OSHA. [1 2] 3.1.8 deflagration vent An opening in a vessel or duct that prevents failure of the vessel or duct due to overpressure. The opening is covered by a pressure-relieving cover (e.g. rupture disk, explosion disk, or hatch). 3.1.9 destructive device A flare, scrubber, incinerator, quench drum, or other similar device used to mitigate the potential consequences of a PRD release. 3.1.10 direct cost Cost of repairs or replacement, cleanup, material disposal, environmental remediation and emergency response. Direct cost does not include indirect costs, such as business opportunity, business interruption and feedstock/product losses, loss of profits due to equipment outages, costs of obtaining or operating temporary facilities, or costs of obtaining replacement products to meet customer demand. Direct cost does not include the cost of the failed component leading to LOPC, if the component is not further damaged by the fire or explosion.
