Workplace Safety and Environmental Sustainability in Horticulture
Safety in horticulture starts with recognising that the hazards change with the task, the season and the site. Candidates must understand the hierarchy of control (eliminate, substitute, isolate, engineer, administrate, then PPE as the last line), because questions often describe a control and ask where it sits. Know the practical basics: hazard and risk are different (a hazard is a source of harm, risk is the likelihood and consequence), safety data sheets (SDS) govern chemical storage, mixing, application and spill response, and PPE must match the product label. Manual handling, sun exposure, noise, vibration, electrical hazards near water, and lone working are recurring themes. Environmental sustainability covers preventing runoff and spray drift, buffer zones near waterways, correct waste segregation, recycling green waste, conserving habitat, and integrated approaches that reduce chemical reliance.
Traps to watch: confusing a hazard with a risk; assuming PPE removes the need for higher-order controls; forgetting that the label and SDS, not habit, dictate rates, re-entry and withholding periods; and mixing up 'biodegradable' with 'safe'. Another common trap is treating sustainability as only about chemicals, when water use, fuel, soil health and biodiversity all count.
Worked rule of thumb: apply the 'STOP' check before any task - Stop, Think, Observe, Plan. If you cannot name the hazard, the control and the emergency response, you are not ready to start. For chemicals, always read the label three times: before purchase, before mixing, and before disposal.
