The Poison in the Shed: Why Every NZ Farmer Must Know Exactly What’s in Their Chemicals—and What to Do When It Hits Skin, Eyes, or Lungs

On a New Zealand farm, chemicals are as common as gumboots. Herbicides, insecticides, fungicides, drenches, disinfectants, fuels, sanitisers, refrigerants, dairy shed acids, alkalis, and veterinary treatments flow through the day like water. The danger is not that farmers use them. The danger is that familiarity breeds blindness.

Every drum, every IBC, every unlabelled spray bottle in the back of the ute contains a chemistry set designed to kill something—fungus, weeds, parasites, bacteria, insects. Sometimes it kills them by burning, sometimes by suffocating, sometimes by shutting down their nervous system. The human body is not immune to these mechanisms. It is just slower to show the damage.

Why Knowing What’s in the Chemical Matters

Not all poisons behave the same. One burns. One paralyses. One starves the blood of oxygen. One silently attacks the liver. One soaks through skin and goes straight into the bloodstream.

If you don’t know:

• The active ingredients

• The route of exposure (skin, eyes, inhalation, ingestion)

• The acute symptoms

• The correct first aid and antidotes

…then you are guessing in a moment where guessing can cost eyesight, lung function, or life.

A splash of alkaline dairy detergent in the eye needs different treatment to organophosphate insecticide on the skin. A lungful of fumigant gas is not managed the same way as herbicide mist. Time is the enemy, and information is the only weapon that moves faster than toxicity.

The Reality of Exposure on Farms

Farmers and farm workers are exposed through:

• Mixing concentrates

• Filling spray units

• Cleaning equipment

• Treating animals

• Washing down dairy sheds

• Fuel handling

• Chemical storage failures

• Drift in still air

• Accidental splashes and spills

Gloves split. Masks slip. Wind shifts. Valves fail. Hoses burst. Human skin becomes the last line of defence.

When that happens, the question is not “What should I do?”
It is “What does this specific chemical require me to do, right now, in the next sixty seconds?”

Safe Treatment Is Chemical-Specific, Not Generic

Some substances:

• Must be washed off immediately with copious water

• Must not be neutralised chemically (it makes the burn worse)

• Require oxygen therapy

• Require atropine or other antidotes

• Must not be induced to vomit

• Must be treated as delayed-effect poisons

The Safety Data Sheet (SDS) is not paperwork. It is a medical instruction manual written in advance of the accident.

But on most farms:

• SDS are in folders no one can find

• Out of date

• Not matched to actual products on site

• Not accessible from the paddock, the dairy, or the cab of a tractor

Why Centralised, Instant Access Is the Missing Link

This is where platforms like ChemMatrix, working alongside Halter, come in.

The vision is simple and powerful:

• Every chemical on the farm

• Every SDS

• Every first aid treatment

• Every emergency response instruction

• Instantly accessible on phone or tablet

• Linked to real-time farm operations and locations

Not buried in a filing cabinet.
Not lost in a ring binder.
Not reliant on memory when adrenaline is high and hands are shaking.

One system. One source of truth. One place to look when something goes wrong.

Compliance Is One Thing. Survival Is Another.

Yes, the Health and Safety at Work Act and HSNO regulations require:

• Hazard identification

• SDS availability

• Worker training

• Emergency response plans

But compliance is paperwork. Survival is knowledge under pressure.

Knowing exactly:

• What is in the product

• How it enters the body

• What damage it causes

• What the correct medical response is

• What not to do

…is what separates a close call from a fatality.

A Straight Talking Message to Farmers

You are surrounded by chemistry designed to kill life forms smaller than you. Sometimes it doesn’t stop at the target species.

Every time you:

• Mix

• Spray

• Drench

• Wash down

• Clean out

• Decant

• Dispose

…you are working with substances that demand respect, not familiarity.

Knowing what is in your chemicals, and the exact first aid and medical treatment required if exposure occurs, is not red tape. It is armour.

And the future lies in having that knowledge instantly, digitally, and in context—through platforms like ChemMatrix, integrated alongside Halter, putting every Safety Data Sheet and emergency treatment protocol in one place, at your fingertips, when seconds matter and memory is not enough.
