10.1 Integrated Pest Management (IPM)
10.1.1 Departments shall develop pest management programs that incorporate Integrated Pest Management (IPM) principles and practices.
10.1.2 When a decision is made to use a pest control product within the context of an IPM program, the department must ensure that employees follow the label instructions so that the product is used safely.
10.1.3 The IPM is a long-standing and science-based decision-making process that identifies and reduces risks from pests and pest-management-related strategies. It coordinates the use of pest biology, environmental information and available technology to prevent unacceptable levels of pest damage by the most economical means, while posing the least possible risk to people, property, resources and the environment
10.1.4 The elements of IPM are
(a) preventing organisms from becoming pest problems by planning and managing ecosystems;
(b) identifying pest and beneficial species;
(c) monitoring pest and beneficial species populations, pest damage and environmental conditions;
(d) using injury and action thresholds to determine when to treat pests;
(e) using treatments that usually include a combination of methods, such as cultural, biological, physical, mechanical, behavioural, or chemical methods, to achieve acceptable control with minimal impact to the environment; and
(f) evaluating the effects and efficacy of pest management strategies.
10.1.5 IPM programs also involve communicating with employees, customers, agencies and the public to inform them of the goals, methods, results and benefits of using IPM.
10.1.6 IPM requires knowing and using available methods in a stepwise approach. Once monitoring, identification and action thresholds indicate that pest control is required and preventive methods are no longer effective or available, IPM programs then evaluate the proper control method for both effectiveness and risk. Effective, reduced-risk pest controls are chosen first, including highly targeted chemicals such as pheromones to disrupt pest mating, or mechanical control, such as trapping or weeding. If further monitoring, identification and action thresholds indicate that the controls are not working then additional pest control methods are employed, such as the targeted spraying of pesticides. Broadcast spraying of non-specific pesticides is a last resort.
Examples of available methods include:
(a) maximizing a plant's health and minimizing its susceptibility to pest infestations by:
(i) crop rotation,
(ii) moisture control,
(iii) planting techniques, and
(b) genetic selection, i.e., using resistant species and varieties of plants;
(c) mechanical controls, e.g., trapping or cultivating or using physical barriers;
(d) approved biological controls, including
(i) parasitic and predatory insects, and
(ii) host-specific pathogens; and
(e) using conventional pesticides in a prescribed manner.
10.2 Work Procedures
10.2.1 Each department in which pesticides are used, handled, stored or disposed of shall ensure that the pesticide label directions and any relevant legislation on pesticide use (federal, provincial or municipal) are followed. For overlapping legislation, the most restrictive is to be adhered to. Supplemental information may also be found on the manufacturer's instructions as detailed on the pesticide label or on a material safety data sheet (MSDS) and/or other manufacturer literature and should be readily available in the workplace and followed.
10.2.2 When, for research purposes or otherwise, deviations from the manufacturer's instructions are required, the use of a pest control product for research purposes must be carried out in accordance with the Pest Control Products (PCP) regulations and may require a ministerial authorization for which an application must be made.
10.2.3 Detailed written procedures about the safe use, handling, storage, transportation and disposal of pesticides, including circumstances in which the employee may be required to work alone shall be developed in consultation with the appropriate health and safety committee, prominently displayed in the workplace, and explained to all employees concerned.
10.2.4 Pesticides shall be used, handled, mixed and disposed of by certified applicators.
10.2.5 When pest control is contracted, contractors shall be certified or licensed in accordance with the applicable provincial requirements; the provisions of the IPM program shall apply.
10.2.6 A spill contingency plan appropriate to the scale of operations shall be in place before any pesticides are applied.
10.3.1 To the extent possible, potentially hazardous pesticide operations should be isolated from the worker or the worker isolated from the operations. Isolation techniques that should be considered include but are not limited to the following:
(a) using positive-pressure tractor cabs with appropriate filtered air supplies;
(b) conducting pesticide operations when the least number of employees are in the area;
(c) using isolation chambers for the research application of high concentrations of toxic pesticides; and
(d) enclosing pesticide transfer points in handling facilities and applying pesticides in an automated manner.
10.4 Protective Equipment and Clothing.
10.4.1 Approved respiratory protective devices, eye protection, and personal protective clothing and equipment appropriate to the potential hazard as identified on the pesticide label and the MSDS, if applicable, shall be provided and worn whenever pesticides are handled or used. Personal protective equipment (including first-aid supplies and portable eyewash stations) shall not be kept in the same storage room as pesticides to avoid contamination. In addition, departments shall provide personal protective equipment and clothing in accordance with the manufacturers' recommendations and Part XIII - Personal and Protective Equipment and Clothing.
10.5.1 To the extent possible, quantities of pesticides purchased and stored shall not exceed the needs of one season in accordance with a pest management program. Pesticides shall be kept in their original, undamaged containers with labels intact and shall be separately stored in locked cabinets. Storage cabinets and rooms shall be vented to the outside with controlled access to avoid unauthorized use. Shelving shall be secure and impervious; and no higher than 150 cm unless specifically designed for safe access above eye level. Appropriate warning signs shall be prominently displayed to identify the locations. Spill control material appropriate to the pesticides in storage shall be maintained at the storage site.
10.6.1 The directions on pesticide labels and provincial requirements for disposing of the product container after use and for disposing of unused or unwanted product shall be followed. Empty pesticide containers shall not be reused for any purpose. During disposal procedures, all possible precautions shall be taken to ensure that persons are not exposed and that pesticides are not released into the environment.
