PEI IMA Grade 9 common mistakes
PEI IMA Grade 9 · Understand the traps and how to avoid them.
Treating the building/structure design domain as generic civil engineering and answering questions about structural loads, foundations, or spans from general construction knowledge instead of the specific requirements that apply to petroleum installation structures such as canopies, dispenser islands, tank pads, and their anchorage and protection.
Candidates come from a construction or engineering background and assume their existing structural knowledge transfers directly, so they answer from habit rather than from the installation-specific requirements, missing items like impact protection for dispensers, island height and layout, and clearance considerations.
What to do instead
Build a one-page summary of the structural and layout requirements that apply specifically to petroleum facilities: dispenser island dimensions and protection, canopy and support considerations, tank pad and anchorage requirements, and vehicle impact protection. For every practice question in this domain, locate the clause in your code set before choosing an answer, and note the clause number beside the answer so you learn the source, not just the fact.
Confusing the different tank types and their installation rules, for example applying underground tank requirements to aboveground tanks, or mixing single-wall and double-wall, or secondary containment rules, when answering fuel storage questions.
The candidate has memorised fragments of tank rules without organising them by tank type, so under exam pressure the requirements blur together and the most familiar rule is applied regardless of the tank described in the question stem.
What to do instead
Create a comparison table with one row per tank type (underground single-wall, underground double-wall, aboveground, and any portable or temporary variants) and columns for containment, monitoring, venting, filling, spill/overfill protection, and separation distances. Fill each cell from the code, then answer practice questions by first identifying the tank type in the stem and reading only that row.
Mixing up the roles and settings of the different dispensing and transfer components, such as shear valves, emergency shutoff valves, anti-siphon devices, check valves, breakaway couplings, and the point at which each must be installed and how it operates.
These devices are all small in-line fittings, so candidates learn them as a list of names without attaching each to its function, its mounting location, and its activation condition, and then cannot distinguish them when a scenario question describes a specific failure or requirement.
What to do instead
For each device, write a three-line card: what it does, where it is installed, and what condition activates it (for example, a shear valve closing on impact or fire, a breakaway coupling separating on drive-away). Draw a simple schematic of a dispenser from tank to nozzle and label every device on it. Practise scenario questions by naming the device on your schematic before reading the answer options.
Answering electrical questions by general electrical intuition without applying the classification rules for hazardous areas, such as which zones or divisions apply around vents, fill points, and dispensers, and which equipment protection methods are permitted in each.
Hazardous area classification is a spatial and rules-based topic that many candidates have never studied formally, so they reason from everyday electrical practice and overlook that the permitted equipment and wiring methods change with distance and location relative to the source of release.
What to do instead
Draw the classified area envelopes around a vent, a fill point, and a dispenser from the code, marking the extent of each zone or division and the equipment permitted in each. Memorise the permitted protection concepts by zone. Then answer questions by sketching the envelope first and locating the described equipment within it before selecting an option.
Confusing bonding and grounding requirements, treating them as one concept, and failing questions about what must be bonded, the resistance or continuity expectations, and the purpose of each connection.
The two terms are used loosely in everyday speech, so candidates do not separate the safety functions: bonding equalises potential between conductive parts, while grounding provides a path to earth. Without that distinction, questions about tank-to-piping bonding, dispenser bonding, or static dissipation are answered by guesswork.
What to do instead
Write a short explanation of each concept in your own words and one example of a failure caused by getting each wrong. List every item in a typical facility that requires bonding and every item requiring grounding, with the code reference. When practising, state which concept the question is testing before looking at the options.
Treating fire safety as a single topic and giving the same answer for different fire scenarios, for example applying the wrong extinguisher class, confusing the purpose of emergency shutoff and emergency venting, or misstating the separation and access requirements that let emergency responders reach the site.
Fire safety questions in this exam are scenario-based, but candidates prepare by memorising isolated facts about extinguishers or fire alarms, so they cannot match the correct protective measure or separation rule to the specific fuel, equipment, or event described.
What to do instead
Organise your notes by scenario rather than by device: vehicle fire at a dispenser, spill fire at a fill point, tank vent fire, and electrical fire in a control panel. For each scenario, list the correct response actions, the devices involved, and the relevant separation, access, and signage requirements. Answer practice questions by identifying the scenario first and then selecting the measure that fits it.
Skipping the environmental protection content, such as spill containment, leak detection, drainage and separator requirements, and vapour recovery, on the assumption that the exam is mainly mechanical and electrical.
Candidates prioritise the technical systems they work with daily and defer the environmental material, which then appears in scenario questions where containment, detection, and drainage decisions are combined with installation choices.
What to do instead
Allocate fixed study sessions to environmental protection and treat it as an equal domain. Build a checklist of containment and detection requirements for each facility element (tank, fill point, dispenser area, drainage) and a separate list of vapour recovery requirements for each stage of the fuel transfer process. Review these checklists weekly until you can recall them without notes.
Answering installation and construction practice questions from field habit, for example describing how a job is normally done on site rather than the sequence, clearances, testing, and documentation the code requires before a system is placed in service.
Experienced installers rely on routines that may omit or reorder steps, and the exam tests the required process, including pre-commissioning checks and records, not the most common site shortcut.
What to do instead
Write the required installation sequence for a tank and for a dispensing system as numbered steps, with the inspection and test that must be completed at each stage and the record that must be produced. Compare your sequence against the code clause by clause and mark any step you have been skipping. Practise questions by asking what the code requires at that stage, not what is usually done.
Confusing inspection, testing, and maintenance activities with each other and with their intervals, for example mixing a periodic leak detection test with a routine maintenance check, or stating an interval without the condition that triggers it.
These activities overlap in practice and the intervals differ by equipment type and by the standard that applies, so candidates who memorise a single list of intervals cannot answer questions that ask which activity applies or when it is due.
What to do instead
Build a matrix with one row per item of equipment and columns for inspection, testing, and maintenance, each with the required interval, the acceptance criterion, and the record to be kept. Where an interval depends on a condition, write the condition in the cell. Rehearse by covering columns and reciting them, then check against the code.
Studying codes and standards as isolated documents and failing questions that hinge on which document governs a situation, how a referenced standard applies, or what a regulator requires versus what a standard recommends.
Candidates often learn one code deeply and treat the others as background, so they cannot resolve questions about the hierarchy of requirements, referenced standards, or the difference between mandatory and advisory provisions.
What to do instead
Create a map of the regulatory framework showing which document covers which subject and how the documents reference each other. For each practice question, record the governing document and clause, and mark whether the provision is mandatory or advisory. Review the map until you can state, for any topic, which document governs and why.
