Sector 05 · Tree Nut Farming

Orchard and hulling hazards across the season.

Tree nut operations run heavy machinery under trees, a processing site with dust and noise, and a workforce that climbs for harvest. Chemical handling and traffic run through all of it. I work the orchard and the processing side as one operation, because that is how the people move through it.

R01

Mobile plant and PTO guarding

Tractors, shakers, sweepers and harvesters working down the rows, with power take-off shafts that need their guards intact. I check guarding, the isolation steps before anyone clears a blockage, and the procedures for working around moving plant.

R02

Dust and noise at hulling

Hulling and processing put dust and sustained noise into the same space. I set up the monitoring, the extraction checks, and the respiratory and hearing protection to match the hours people spend there.

R03

Spray handling and re-entry

Handling, mixing and application each carry their own controls, and the re-entry interval decides when anyone can go back into a block. I get the SDS, the chemical register and the re-entry rules recorded and followed on the ground.

R04

Seasonal crews and turnover

Headcount climbs for harvest and much of it is new every season. I build a short site-specific induction so a first-day worker knows the plant, the traffic routes and the chemical areas before they start.

R05

Heat

Long days in the orchard, and hot work areas at the processing end. I set the heat controls, the water and rest arrangements, and the trigger points for changing or stopping the work.

R06

Traffic between orchard and processing

Trucks, bins and machinery moving between the blocks and the plant, sharing tracks with light vehicles and people on foot. I set the routes, the speeds and the separation.

Common questions

Questions I get asked

What are the main hazards in a tree nut operation?
Mobile plant working under trees, power take-off shafts, dust and noise at hulling, chemical handling and spray re-entry, heat through the season, and traffic between the blocks and the processing site.
What guarding do orchard machines need?
PTO shafts need their guards intact and in place, and that is the guard most often found missing or damaged. Shakers, sweepers and augers need guarding on drives and intake points, with a documented isolation step before anyone clears a blockage.
What is a re-entry interval?
It is the period after a chemical application before anyone can go back into the block. It comes off the product label and it is a legal requirement. It has to be recorded and communicated to everyone working the orchard, contractors included.
How do I manage a large seasonal crew?
A short, site-specific induction before the first shift, covering the plant, the traffic routes and the chemical areas. Turnover is the problem to design around, so the induction has to be quick to deliver and easy to repeat.
What are my obligations for working in heat?
You have to manage the risk so far as is reasonably practicable. In practice that means water, shade and rest, adjusting the work through the hottest part of the day, and trigger points that say when work changes or stops. Put it in writing before the season starts.

Ahead of harvest

The pre-season check

  • an orchard and plant walk
  • guarding and PTO checks
  • chemical register and re-entry intervals reviewed
