Why Chemical Storage Matters on the Ranch

Every ranch has chemicals — herbicides, pesticides, fertilizers, veterinary products, fuels, and cleaning supplies. Poor storage is one of the top causes of preventable livestock poisoning. Curious cattle can get into unsecured storage areas, eat spilled products, or drink contaminated runoff.

This guide covers storage practices, facility requirements, inventory management, and emergency response procedures to keep your livestock safe from chemical exposure.

Common Agricultural Chemicals and Their Hazards

Herbicides and Pesticides

|-------------|----------|----------------| | Organophosphates | Malathion, Diazinon | Nervous system | | Paraquat | Gramoxone | Pulmonary damage | | Strychnine | Some rodenticides | Seizures, death | | Arsenic compounds | Some historical products | Multiple organ | | Carbamates | Sevin, Temik | Nervous system |

  • Glyphosate (Roundup)
  • Atrazine
  • Most modern insecticides

Fertilizers

  • Urea (nitrogen toxicity if consumed)
  • Anhydrous ammonia (severe burns, respiratory)
  • Superphosphate (gastrointestinal irritation)
  • Nitrogen fertilizers cause rapid toxicity
  • Can contaminate water sources

Veterinary Products

  • Antibiotics (resistance concerns)
  • Hormonal implants (off-label exposure)
  • Tranquilizers and sedatives
  • Euthanasia solutions

Fuels and Lubricants

  • Gasoline (inhalation, ingestion)
  • Diesel (gastrointestinal, aspiration)
  • Used motor oil (heavy metals, carcinogens)
  • Hydraulic fluid (toxicity varies)
  • Antifreeze (highly attractive, deadly)

Storage Facility Requirements

Minimum Standards

  • Away from livestock feeding areas
  • Not in flood-prone areas
  • Accessible for emergency response
  • Away from hay and feed storage
  • Solid walls (livestock can't push through)
  • Concrete or impermeable floor
  • Containment for spills (bermed or diked)
  • Adequate ventilation
  • Protection from temperature extremes
  • Floor: Sealed concrete, sloped to drain
  • Containment: 110% of largest container volume
  • Shelving: Metal or plastic (not wood)
  • Lighting: Adequate for reading labels
  • Ventilation: Exhaust fan minimum
  • Fire extinguisher: ABC rated, near entrance
```
  • Hinges on inside or pinned
  • No windows at ground level (or secured)
  • Perimeter fencing if practical

Temperature Considerations

  • Some herbicides - above freezing
  • Liquid fertilizers - prevent freezing
  • Petroleum products - away from heat sources

Separation Requirements

|---------------|----------------|--------| | Fertilizers | Pesticides | Chemical reaction | | Oxidizers | Fuels | Fire/explosion | | Acids | Bases | Violent reaction | | Herbicides | Seed | Contamination | | Rodenticides | Feed | Accidental mixing |

Inventory Management

Product Tracking

  • Date purchased
  • Quantity on hand
  • Location in storage
  • Expiration date
  • Safety Data Sheet location
ProductAmountDateExpiresLocationSDS
Roundup5 gal3/253/28Shelf A2Yes
```

Disposal Protocols

  • Pouring down drains
  • Burning containers
  • Burying on property
  • Leaving accessible to livestock
  • Licensed hazardous waste contractors
  • Manufacturer take-back programs
  • Container recycling programs
  • Puncture to prevent reuse
  • Participate in container recycling programs
  • Never reuse for feed or water

Rotating Stock

  • Check dates when purchasing
  • Don't stockpile beyond needs
  • Dispose of expired products properly

Spill Prevention and Response

Prevention Measures

  • Use pumps for large containers
  • Keep containers closed when not in use
  • Inspect containers for damage before moving
  • Never leave containers unattended open
  • Secure against tipping
  • Keep lids tight
  • Inspect regularly for leaks
  • Address corrosion promptly

Spill Response Kit

  • Plastic bags for containment
  • Personal protective equipment (gloves, goggles)
  • Broom and dustpan (dedicated to spill use)
  • Copy of Safety Data Sheets
  • Emergency contact numbers

Response Procedures

  • Stop source of spill
  • Contain spread with absorbent
  • Collect contaminated material
  • Dispose properly
  • Document incident
  • Secure livestock away from area
  • Call emergency responders if needed
  • Contain if safely possible
  • Notify appropriate agencies
  • Document thoroughly

Reporting Requirements

  • Spills exceeding label threshold amounts
  • Pesticide drift incidents
  • Any release requiring evacuation
  • Texas Department of Agriculture (pesticide issues)
  • Local fire department (fire/explosion risk)
---

Livestock Protection Measures

Physical Barriers

  • Minimum 50-foot setback from storage building
  • Gates must be self-closing and lockable
  • No gaps animals can push through
  • Regular inspection of integrity

Environmental Controls

  • Contain any potentially contaminated water
  • Grade area to prevent pooling
  • Fence off until remediated
  • Test soil before returning to livestock use

Operational Procedures

  • Use designated mixing area with containment
  • Triple-rinse equipment over containment
  • Return unused product to storage
  • Follow label grazing restrictions
  • Mark treated areas clearly
  • Document application dates and products

  • Nearest poison control center
  • Veterinarian emergency contact
  • Local emergency response numbers
  • Basic spill response procedures
  • How to contact emergency services
  • First aid for chemical exposure

If Livestock Exposure Occurs

  • Identify the chemical involved
  • Call veterinarian with chemical name

  • Product involved
  • Estimated exposure amount
  • Actions taken
  • Veterinary treatment provided
  • Outcome
