3.1.25
process safety event
PSE
An unplanned or uncontrolled LOPC of any material including non-toxic and non-flammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air) from a process, or an undesired event or condition that, under slightly different circumstances, could have resulted in a LOPC of a material.
3.1.26
public receptors
Offsite residences, institutions (e.g. schools, hospitals), industrial, commercial, and office buildings, parks or recreational areas where members of the public could potentially be exposed to toxic concentrations, radiant heat, or overpressure, as a result of a LOPC.
3.1.27
recordable injury
A work-related injury that results in any of the following: death, days away from work, restricted work or transfer to another job, medical treatment beyond first aid, loss of consciousness, or a significant injury diagnosed 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. [12]
3.1.28
third-party
Any individual other than an employee, contractor or subcontractor of the Company [e.g., visitors, non-contracted delivery drivers (e.g. UPS, U.S. Mail, Federal Express), residents, etc.].
3.1.29
tolling operation
A company with specialized equipment that processes raw materials or semi-finished goods for another company.
3.1.30
total work hours
Total employee, contractor, and subcontractor hours worked minus the hours associated with major construction projects. This is the same number typically used to calculate occupational injury and illness rates.
3.1.31
United Nations Dangerous Goods
UNDG
A classification system used to evaluate the potential hazards of various chemicals when released, which is used by most international countries as part of the product labeling or shipping information [10] In the United States, these hazard categories are defined in U.S. Department of Transportation (DOT) regulations 49 CFR 1 73.2a 114], and listed in 49 CFR 172, Subpart B. L131
3.1.32
unsafe location
An atmospheric pressure relief device discharge point or downstream destructive device (e.g. flare, scrubber) discharge point that results in a potential hazard, such as the formation of flammable mixtures at grade level or on elevated work structures, presence of toxic or corrosive materials at grade or on elevated work structures, or ignition of relief streams at the point of emission as specified in API 521 Section 6.3.4.3. [2]
6 Tier 2 Performance Indicator—Process Safety Events (T-2 PSE)
6.1 Tier 2 Indicator Purpose
The count of Tier 2 process safety events represents LOPC events with a lesser consequence. Tier 2 PSEs, even those that have been contained by secondary systems, indicate barrier system weaknesses that may be potential precursors of future, more significant incidents. In that sense, Tier 2 PSEs can provide a company with opportunities for learning and improvement of its process safety performance.
6.2 Tier 2 Indicator Definition and Consequences
A Tier 2 Process Safety Event (T-2 PSE) is a LOPC with lesser consequence. A T-2 PSE is an unplanned or uncontrolled release of any material, including non-toxic and non-flammable materials (e.g. steam, hot condensate, nitrogen, compressed CO2 or compressed air), from a process that results in one or more of the consequences listed below and is not reported in Tier 1:
NOTE Non-toxic and non-flammable materials (e.g. steam, hot water, nitrogen, compressed CO2 or compressed air) have no threshold quantities and are only included in this definition as a result of their potential to result in one of the other consequences.
— an employee, contractor or subcontractor recordable injury;
a fire or explosion resulting in greater than or equal to $2,500 of direct cost to the Company;
— a pressure relief device (PRD) discharge to atmosphere whether directly or via a downstream destructive device that results in one or more of the following four consequences:
— liquid carryover;
— discharge to a potentially unsafe location;
— an on-site shelter-in-place;
— public protective measures (e.g. road closure);
and a PRD discharge quantity greater than the threshold quantity in Table 2 in any one-hour period.
