Procedure: Pest management

Purpose

The purpose of this procedure is to detail the process for managing pests and pesticides at the Australian National University (University). This Pest Management procedure ensures that legal and other obligations of the Work Health and Safety Act, 2011 (Cth) (WHS Act), the Work Health and Safety Regulations, 2011 (Cth) (WHS Regulations) and the Safety, Rehabilitation and Compensation Act, 1988 (SRC Act) are defined for managing the health and safety of all workers. This procedure is linked to the Australian National University’s Workplace Health and Safety Policy and is one of the WHS Management System Procedures located on the Work Environment Group web page.

Definitions

Authorised person is a person authorised by local management to undertake explicit pesticide operations. An authorised person must have the appropriate competency for the application to be undertaken. Also see competent person.

Local area is the relevant College, Research School or Service Division at the Australian National University.

Competent person is a person who has acquired through training, qualifications and experience the knowledge and skills to carry out the task. The following may be considered competent persons for this procedure: a pest control operator employed by a registered pest control firm; a horticulturist having studied pesticide usage; or a person having undertaken registered training in the management and application of pesticides.

Emergency Procedures are plans, established in advance, stating what action to take in the event of an emergency. These are used in order to minimise the consequences of an incident, such as injuries, or damage to property or the environment.

Exposure occurs when a person, property or the environment comes into contact with a hazard. The four routes of exposure for people are: inhalation, skin absorption, ingestion and inoculation.

Fumigation is the process whereby a fumigant is released within a controlled target volume; it is one type of pesticide application.

Fumigant is a pesticide that has a significant vapour pressure at normal temperature and pressure.

Hazard is anything that has the potential to cause harm.

Hazardous chemical is any chemical substance that has the ability to release energy that is harmful to the health or safety of a person or the environment. This definition includes hazardous substances, dangerous goods, and scheduled drugs and poisons.

Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (World Health Organisation (WHO) definition).

Health hazard is anything that can cause illness or disease. Exposure may occur over a short or long period of time.

Integrated pest management refers to the process of pest control within a defined tolerance level by the use of biological, physical and organisational factors, in addition to chemicals. The defined tolerance level is the level of pest infestation that has a significant deleterious effect on the primary objective (e.g. research project, economic viability, visual aesthetics). Biological factors would include the natural predators and parasites of the pest. Physical factors would include temperature, humidity, light and UV. Organisational factors would include isolation (glasshouses/pens/paddocks), insect screening of plants, restricted access of persons, pest-sensitive experiments in special facilities, and importantly, appropriate timing and quantity of any pesticide application to ensure effective pest control at their most damaging stage.

Pest refers to an unwanted biological entity; including animals, plants and microbes.

Pesticides are chemicals (or mixture of chemicals) intended to be used for the selective control of pests. For example, insecticides, fungicides, or rodenticides.

Pesticide application is the dispersal of a pesticide over a target area or volume. Pesticide application is the process whereby a solid, liquid or solution pesticide (with no significant vapour pressure) is dispersed to settle in the target volume; but the term also includes the process of fumigation.

Pesticide operation includes any or all of the processes of pesticide acquisition, storage, mixing, application, and disposal.

Risk is the likelihood that a hazard will cause harm in the given circumstances and the consequences if it does.

Risk control is a strategy that is implemented to eliminate or, if it cannot be eliminated, reduce the risk associated with an identified hazard.

Safety Data Sheet (SDS) is a document that provides necessary information about the toxicity, storage and handling of hazardous chemicals. These documents are produced by the manufacturer or importer of each hazardous chemical. SDS’s are also available through the ANU chemical management database Chemwatch.

Safe Work Method Statements (SWMS) are a set of instructions designed to communicate definite or standardised procedures to staff. These are used to obtain consistency in results and increase safety and efficiency in the workplace. Also known as Safe Operating Procedures, Protocols etc.

Procedure

Emergency information

  1. Initially direct emergency queries to local area management, then Work Environment Group, HR Division (02) 6125 2193 or internal extension (x52193). The local area is responsible for coordinating any Emergency Services response.

Disposal of pesticides and pesticide containers

  1. All pesticide disposals shall be in accordance with legislative requirements and the University’s Chemical Handling procedure.
  2. All mixed pesticide that is unused after an application shall be retained and used as part of the next batch made up. Ideally each pesticide should have a dedicated applicator.
  3. All empty pesticide containers must be triple rinsed and punctured. The rinse water shall be stored in the dedicated applicator for that pesticide and used to make up the next batch. The rinsed pesticide containers shall be disposed of according to the procedures of the ACT Environment Act.
  4. Disposal of many waste materials is covered in the University's Hazardous Waste documentation. Wastes must be collected in suitable containers only with other compatible chemicals
    See: University's Disposal of Hazardous Waste procedure, chemical waste collection in suitable containers and compatible chemicals.
  5. Hazardous waste safety officers with specialised knowledge on the disposal of chemicals are located in many areas on campus. If a Hazardous Waste Safety Officer is not able to resolve an issue related to waste chemicals, the issue should be referred to WEG. The Hazardous Waste Safety Committee oversees the University's waste chemical processes (See: Hazardous waste safety officers, Hazardous Waste Safety Committee and the Work Environment Group).

Incident reporting

  1. The reporting of incidents, significant exposures and dangerous incidents assists the University community avoiding repeated incidents. All incidents involving the storage and handling of pesticides at the university must be reported via the University's on-line Incident Notification Form (See: University's on-line Incident Notification Form).

Emergency procedures

  1. Potential emergencies shall be considered in the storage and handling of pesticides BEFORE any pesticides are used. Local and University emergency procedures should be considered (See: University emergency procedures and Chemical Handling Protocol).
  2. All authorised persons must be familiar with the First Aid Procedures for exposure to pesticides. First Aid Procedures should take into account:
  • unusual or unique first aid or medical treatments
  • specific treatment items must be obtained before handling the chemicals that require the specific treatments and
  • awareness or education of First aid officers in the requirements for, and locations of, unusual or unique treatments.
  1. Appropriate types and amounts of spill containment resources and absorbing materials shall be made available before commencing any procedure with pesticides.
  2. The risk of fires and adverse chemical reactions should be identified and appropriate risk reduction measures employed.

Training obligations/courses

  1. WEG runs chemical safety courses. Some local OHS Committees have made these courses compulsorily for new chemical users. Local induction must cover aspects of pesticide safety and management requirements for relevant staff. Specific pesticide handling training is available through external register training organisations (See: Chemical safety courses, and Work Environment Group).
