Hazard

A source or situation with the potential to cause harm, such as an unguarded drive shaft, a chemical spill or a slippery floor.

Risk

The likelihood and consequence of harm occurring from exposure to a hazard, assessed before controls are chosen and applied.

Hierarchy of control

A ranked order of risk controls from most to least effective: eliminate, substitute, isolate, engineer, administrative controls, then personal protective equipment.

PCBU

A person conducting a business or undertaking, who holds the primary duty to ensure health and safety so far as reasonably practicable.

Notifiable incident

A death, serious injury or illness, or dangerous incident that must be reported to the work health and safety regulator immediately.

Safety Data Sheet

A document providing hazard, handling, storage, first aid and disposal information for a hazardous chemical; it must be readily accessible.

Withholding period

The minimum time between applying a chemical and harvesting, grazing or slaughtering, so residues do not exceed permitted limits.

Re-entry period

The time that must pass after a chemical application before people may safely re-enter the treated area without protective equipment.

Personal protective equipment

Clothing and equipment worn to reduce exposure to hazards, such as gloves, respirators, hearing protection and high-visibility garments.

Manual handling

Lifting, lowering, pushing, pulling or carrying a load; risk is reduced by mechanical aids, team lifting and correct technique.

Emergency assembly point

A designated safe location where workers gather and are accounted for after an evacuation or emergency alarm.

Soil texture

The relative proportions of sand, silt and clay particles, which determine drainage, water-holding capacity and workability.

Soil pH

A measure of soil acidity or alkalinity; most crops and pastures grow best between about pH 5.5 and 7.0.

Macronutrients

Nutrients required in larger amounts: nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, essential for plant growth.

Micronutrients

Nutrients needed in very small amounts, including iron, manganese, zinc, copper, boron and molybdenum, yet essential for plant health.

Integrated pest management

A strategy combining monitoring, cultural and biological controls with targeted chemicals, applied only when pest thresholds are exceeded.

Five Freedoms

Animal welfare principles covering freedom from hunger and thirst, discomfort, pain, injury and disease, and fear, plus normal behaviour.

Biosecurity

Measures that prevent the introduction and spread of pests and diseases, such as visitor logs, clean footwear and restricted entry.

Traceability

The ability to track produce, livestock or inputs through production and supply records, supporting recalls and compliance.

Gross margin

Gross income from an enterprise minus its variable costs; used to compare the profitability of alternative enterprises.

Break-even point

The level of production or sales at which total income equals total costs, so the enterprise makes neither profit nor loss.

Triple bottom line

Assessing a system against economic viability, environmental stewardship and social responsibility rather than profit alone.

Riparian zone

The vegetated strip beside a waterway that filters runoff, stabilises banks and provides habitat for aquatic and terrestrial species.

Spray drift

Movement of pesticide away from the target area by wind or air currents; reduced by correct nozzles, pressure and weather conditions.

Power take-off

A splined shaft transferring engine power to implements; it must be fully guarded whenever the engine is running.

ROPS

Roll-over protective structure fitted to a tractor and used with a seatbelt to protect the operator in a rollover.

Kickback

Sudden upward and backward movement of a chainsaw when the nose of the guide bar contacts an object; reduced by correct technique.

Flight zone

The space around an animal within which it moves away when a handler enters; used to move livestock calmly.

Point of balance

The position near the animal's shoulder where handler movement directs it forward or backward during handling.

DRSABCD

First aid action sequence: danger, response, send for help, airway, breathing, cardiopulmonary resuscitation, defibrillation.

Hearing protection threshold

Hearing protection is required where noise exposure reaches or exceeds 85 decibels averaged over eight hours.

Machine guarding

Physical barriers over belts, chains, gears and shafts that prevent contact with moving parts during operation.
