Identifying airborne contaminants in Agriculture
Agricultural work often involves tasks and environments where airborne contaminants can build up without being noticed. Dusts from grain, fertiliser, soil and animal areas, fumes from machinery and welding, vapours from pesticides, and even moulds or microorganisms in sheds and storage spaces can all affect the air that workers breathe.
Some of these hazards have a strong smell or are visible in the air, but many are completely invisible and odourless, which means people may be exposed without realising it. That’s why anyone running or managing an agricultural workplace needs to pay close attention to the conditions around them—looking at how equipment is used, how tidy and well‑maintained work areas are, and whether dust, residue or exhaust is building up on surfaces or in the air.
What can you do?
- Talking with workers is essential, as they often know which tasks create dusts, fumes or vapours, and can describe whether certain jobs make them cough, itch or feel unwell.
- Read labels and safety data sheets for chemicals and materials to help you understand what might be harmful.
- Seek advice from professionals such as occupational hygienists to provide clarity when hazards are harder to identify.
Because farm work changes with the seasons, weather and new processes, checking for airborne contaminants isn’t something you do once—it’s an ongoing part of keeping people safe. By staying alert, reassessing regularly and taking action early, you help protect workers, visitors and neighbours from preventable health risks linked to poor air quality.
