Year 2 Exam Study Guide — master what the exam actually tests, concept by concept.
Construction sites are one of the most hazardous work environments in Canada. Fall protection, scaffold safety, struck-by and caught-in hazards are among the leading causes of fatalities. This section ensures you can identify hazards, apply controls, and know the regulations that protect workers.
Most plants prefer 6.0-7.0 pH; acidic (< 6.0) and alkaline (> 7.0) limit nutrient availability. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Head spacing: 2-3× throw distance for overlap (e.g., 30-foot sprinkler = 60-90 foot spacing). Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
foot sprinkler = 60-90 foot spacing)
IPM: cultural (correct spacing), biological (predators), mechanical (traps), then chemical if needed. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Pesticide safety: read label, SDS, follow mixing/application rates, wear protective equipment. Safety regulations exist because the consequences of ignoring them are severe — injury, death, or legal liability. Know these requirements the way you know your own name.
Hedge timing: spring to midsummer (2-3 shears); stop by August to harden growth. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Building codes, fire codes, and workplace regulations define the minimum standards that protect occupants and workers. These aren't guidelines — they're legal requirements. Knowing your applicable codes means fewer failed inspections, less rework, and a professional reputation that lasts.
Fertilizer label: N (leaf growth), P (root/flower), K (overall health); 10-10-10 = balanced. Memorize this formula and practise substituting values — exam questions often give you three variables and ask you to solve for the fourth.
Amendments: compost (water/nutrient holding), sand (drainage), perlite/vermiculite (aeration). Material selection directly affects performance, code compliance, and longevity. Using the wrong type can fail an inspection or create a hazard down the line.
Construction materials have specific strengths, limitations, and proper applications. Choosing the wrong adhesive, fastener, or structural member isn't just a quality issue — it can be a structural failure waiting to happen. Know your materials.
Fruit tree forms: central leader (apple), open center (peach); pruning establishes framework. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Retaining wall: compacted base, proper backfill/drainage (prevent water pressure), plumb face. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
Quality construction depends on proper sequence, technique, and workmanship standards. Whether it's concrete curing, wood framing, or tile installation — how you do it determines how long it lasts. These questions test the procedural knowledge that defines trade-level competency.
Precipitation rate: in/hour; turf needs 1-2 in/week; adjust head selection/spacing. On the job, a solid grasp of this concept means faster decisions, fewer errors, and work that passes inspection the first time.
