Ontario Pesticide Structural Exam case studies
Ontario Pesticide Structural Exam · Put your knowledge to work in context.
The Ontario structural pesticide applicator credential authorizes the application of pesticides in and around buildings - apartments, restaurants, warehouses, schools, hospitals, food plants and similar structures - for pests such as cockroaches, bed bugs, ants, rodents, stored-product insects and occasional invaders. Candidates are typically technicians entering the pest control industry, experienced applicators adding a class to an existing licence, or supervisors who need to understand what their staff do and why. The Ontario Pesticide Structural Exam case studies are 5 cases and about 3,970 words.

In February a technician loads two 10 L jugs of a pyrethroid emulsifying concentrate and a case of aerosol cans into the back of an unpartitioned van and drives to a job. On a residential street he brakes hard: one jug tips, the cap cracks, and roughly 6 L of concentrate spreads across the cargo floor and out the open rear door onto the asphalt, running in a thin film toward a curb inlet that discharges to a creek.
