After starting my first trucking job during harvest, one thing became obvious very quickly.
Grain dust gets everywhere.
When we’re unloading hopper-bottom trailers or end dumps into farm grain bins, a cloud of dust can hang in the air for 15 to 20 minutes while the trailer empties.
You finish unloading and your boots, shirt, hat, and even your face are covered with dust.
After experiencing that myself, I decided I didn’t want my lungs getting coated with it too.
If you haven’t already, I recommend reading Is Corn Dust Harmful to Breathe? What Every Grain Truck Driver Should Know because it explains why repeated exposure to grain dust deserves to be taken seriously. Grain dust can irritate the eyes, skin, and respiratory system, and repeated exposure has been associated with chronic respiratory problems in some workers.
Wear a Proper Respirator
The single biggest change I’ve made is wearing a reusable respirator whenever I know I’ll be standing in heavy grain dust.
A loose paper dust mask is certainly better than nothing, but I wanted something that seals much better around my face.
I’ve been using the 3M P100/OV Odor & Particulate Reusable Respirator during harvest because it’s comfortable enough to wear while unloading, provides an excellent seal when fitted correctly, and uses P100 particulate filtration, which is designed to capture at least 99.97% of airborne particles.
Since I started wearing it, I don’t end the day tasting grain dust every time I unload.
Stay Out of the Dust Cloud When You Can
Sometimes you have to be beside the trailer.
Other times, you don’t.
If the trailer is unloading properly and you don’t need to stand right beside it, take a few steps away from the dust.
Even something as simple as standing upwind instead of downwind can noticeably reduce how much dust you’re breathing.
I know that’s not always possible depending on the wind and the setup, but it’s something I pay attention to now.
Protect Your Eyes Too
One thing I wasn’t expecting was how irritating grain dust can be on your eyes.
On windy days, dust can blow directly into your face while you’re waiting for the trailer to finish unloading.
A good pair of wraparound safety glasses or clear safety glasses helps keep dust out of your eyes while still allowing you to see what the trailer is doing.
If you already keep safety glasses in your truck for pre-trips or other work, they’re worth wearing during unloading too. OSHA recommends appropriate eye protection for dusty work environments where airborne particles can contact the eyes.
Wash Up Before Eating
It sounds simple, but it’s easy to forget during a busy harvest day.
If your hands, face, and beard are covered with grain dust, take a minute to wash up before grabbing lunch or a snack.
You’re already breathing enough dust during unloading.
There’s no reason to accidentally eat it too.
Keep Dust Out of Your Truck
Your truck quickly becomes dusty during harvest if you’re climbing in and out all day.
I’ve started making a habit of knocking the dust off my boots before climbing back into the cab.
It also helps to keep the windows rolled up whenever you’re parked near unloading operations.
It won’t eliminate all the dust, but it keeps the inside of the truck a lot cleaner over the course of harvest.
Don’t Ignore Your Body
If you notice that you’re coughing every evening, your chest feels tight, you’re wheezing, or you’re becoming short of breath after working around grain, don’t simply assume that’s normal. Those warning signs can also warrant a closer look at symptoms after working around grain.
Those symptoms can have many causes, but grain dust exposure is known to irritate the respiratory system, especially with repeated exposure. A closer explanation of that irritation and the body's coughing response appears in how grain dust irritates your airways.
If symptoms continue or become severe, it’s worth discussing them with a healthcare professional rather than hoping they’ll eventually go away.
Frequently Asked Questions
Is standing upwind really helpful?
Yes. Whenever the wind allows, standing outside the main dust cloud reduces the amount of airborne grain dust you’re exposed to while unloading.
Should I wear eye protection around grain dust?
I think it’s a good idea. Grain dust can easily blow into your eyes during unloading, and wraparound safety glasses provide an extra layer of protection in dusty conditions.
Is a reusable respirator worth it?
If you’re around grain dust regularly like I am during harvest, I think so. A properly fitted reusable respirator with P100 filters offers significantly better particulate filtration than a loose-fitting paper dust mask.
Should I wear a respirator every time I unload?
That’s a personal decision, but if you’re going to be standing in a heavy dust cloud for 15 to 20 minutes at a time, especially day after day throughout harvest, wearing one is a simple way to reduce your exposure.
