Part 2: Tank Inspection Date of Last Test Tank ID Code Less than or equal to a 36-month period (in accordance to B620 Table 7.1, Periodic Inspection and Test Intervals ). The external inspection period may be extended to 3 years for tanks outlined in CSA B622, clause 6.3, specific requirement 55. Markings on tanks must be legible (CSA B620 7.2.1.1[e]). Record all test markings on tanks below. Test Dates (mm/yy): Safety Requirements Close proximity to Fresh Water; take note of wind direction (always approach upwind); goggles; gloves; safety boots; and NH3 protective suit. General Information for Quick Reference Litres to US gallons = X / 3.77 US gallons to litres = X * 3.77 kpa to PSI = X * 0.145 PSI to kpa = X * 6.89 Nominal Thickness : Tank Body.375 in. (9.53 mm) for Westeel tanks Tank Ends.322 in. (8.18 mm) for Westeel tanks Consult with manufacturer of other tanks for their thicknesses. General Equipment Required Ladder, metal ruler, telescoping mirror, metal scraper, wire brush, and picks. A caliper is required only if a certification for a Thickness Test is granted to the testing facility. Tank Preparation Tank is free of any dirt and debris that would otherwise hinder any observations to tank shell; all external attachments (i.e. water tank, safety kit, etc.) are removed.

Inspect entire area of tank for dents, scrapes, distortions, gouges, bulges, cracks, signs of leakage or any other condition that might render it unsafe for transport (7.2.1.1 [a]). Tank Shell Inspection Rejection Criteria: Defects less than the minimum thickness remaining under a cut, dig, or gouge (10% less than the nominal thickness) [7.2.2.2(a)] Any dent with a depth of more than 12.7 mm (0.5 in) where it includes a weld (7.2.2.2[b]) Any dent with a depth of greater than 10% of the length of the dent (7.2.2.2 [c]) Any structural defect (7.2.2.2 [e]) Any source of leakage (7.2.2.2[f]) Inspect entire area of tank for: corrosion, abrasions, and signs of leakage or any other condition that might render it unsafe for transport (7.2.1.1 [a]). Rejection Criteria: Defects less than the minimum thickness remaining under a cut, dig, or gouge (10% less than the nominal thickness) (7.2.2.2 [a]). Any source of leakage (7.2.2.2 [f]). Ensure all appurtenances (any tank part or accessory that has no product containment function and provides no structural support to tank [i.e. PRV guards, weld pad]) and attachments, support structures, or connecting structures are not damaged or corroded so as to affect safe operation of the tank (7.2.1.1[f]). Rejection Criteria: Includes any structural defect (7.2.2.2 [e]) Repairs made to liquid retaining components using overlay patches (7.2.2.2[g]) Page 3 of 8 74
Inspect every weld on all appurtenances (any tank part or accessory that has no product containment function and provides no structural support to tank i.e. PRV guards, weld pad) for cracks, defects, or signs of leakage (7.2.1.1 (a)). Rejection criteria: Any dent with a depth of more than 12.7mm (0.5 in) where it includes a weld (7.2.2.2(b)). Includes any weld defect, including a crack, pinhole, or incomplete fusion of weld (7.2.2.2(d)). Inspect every tank head circumference weld and rear tank circumference weld for cracks, defects, or signs of leakage (7.2.1.1 (a)). Rejection criteria: Any dent with a depth of more than 12.7mm (0.5 in) where it includes a weld (7.2.2.2(b)). Includes any weld defect, including a crack, pinhole, or incomplete fusion of weld (7.2.2.2(d)). Any source of leakage (7.2.2.2 (f)). Inspect every longitudinal tank weld and mid tank circumference weld for cracks, defects, or signs of leakage (7.2.1.1 (a)). Rejection criteria: Any dent with a depth of more than 12.7mm (0.5 in) where it includes a weld (7.2.2.2(b)). Includes any weld defect, including a crack, pinhole, or incomplete fusion of weld (7.2.2.2(d)). Any source of leakage (7.2.2.2 (f)). Page 4 of 8 75
Inspect all valves and valve welds including self closing stop valves, excess flow valves, and pressure relief valves for corrosion, distortion, wear, signs of leakage, or any other damage that would prevent their normal operation (7.2.1.1(c)). Ensure PRV rating matches the data plate rating and record PRV expiry date! PRV 1 PSI rating: PRV 1 expiry date PRV 2 PSI rating: PRV 2 expiry date For Twin Tank Wagons: Ensure all bolts or nuts on any flanged connection or blank flange are in place and properly tightened (7.2.1.1(d)). Ensure that hose assemblies mounted on or accompanying the tank does not display any of the rejection criteria listed below 7.2.1.1 (g)). Rejection criteria 7.2.10.4: Hose assembly bolts missing or loose Hose couplings show excessive wear or damage Hose has exposed reinforcement showing The wire braid is kinked, flattened, or permanently deformed Hose bulges under pressure or has soft spots when not under pressure Loose outer covering Hose serial number or ID and HAWP deteriorated legibly or absent Hose markings are displayed as follows (7.2.10.6): Hose tag securely fastened Letter on tag are not less than 5 mm (0.2 in.) high The month and year of test and inspection are stamped on tag Page 5 of 8 76
Corroded or abraded area of the tank wall shall have their thickness tested in accordance with Clause 7.2.6. (7.2.1.3) NOTE: Must be registered with Transport Canada (TC) to conduct thickness testing. If thickness testing is performed, please indicate the TC registered facility that conducted the thickness testing and attach the report. Inspect all re-closing pressure relief valves for any corrosion or damage that could prevent their safe operation. (7.2.1.4 (a)) Inspect all gauges (pressure gauge, float gauges, etc) for corrosion, distortion, wear, signs of leakage, or any other damage that would prevent their normal operation. Page 6 of 8 77

Month and year of inspection. 2. The letter V. 3. The last three digits of your facility registration number given by Transport Canada. The markings should appear as follows: 06 08 V 123 (where 123 is the TC registered facility number). Markings applied as follows: Month/Year of Visual Inspection V marking affixed: Part 4: Tank Status After External Visual Inspection Tank removed from service for repairs Yes Tank returned to service Tank to be scrapped NOTE: Facilities must be registered with Transport Canada (TC) to conduct any repairs to the structural integrity of the tank i.e. welding. If any repairs have been performed directly on the tank body, please indicate the TC registered facility that conducted the repairs and attach the report.
