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
Recommended Specifications
- 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
| Product | Amount | Date | Expires | Location | SDS |
|---|---|---|---|---|---|
| Roundup | 5 gal | 3/25 | 3/28 | Shelf A2 | Yes |
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
Emergency Response Planning
Pre-Incident Preparation
- Safety Data Sheets for each product
- 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
- Have Safety Data Sheet available
- Follow veterinary guidance
- Active ingredients (from label or SDS)
- Estimated amount consumed/contacted
- Time of exposure
- Current symptoms
- Number of animals affected
Documentation
- Animals involved
- Product involved
- Estimated exposure amount
- Actions taken
- Veterinary treatment provided
- Outcome
Regulatory Compliance
Federal Requirements
- Training requirements
- PPE requirements
- Restricted entry intervals
- Safety Data Sheet availability
- Employee training
Texas Requirements
- Restricted-use pesticide regulations
- Record-keeping requirements
- Spill reporting requirements
- Water quality protection
Record Keeping
- Purchases and inventory
- Disposal documentation
- Training records
- Incident reports
Annual Safety Audit Checklist

- Use propylene glycol alternatives when possible
- Dispose of properly—never dump
Rodenticides
- Secondary poisoning from consuming dead rodents
- Long-lasting effects (anticoagulants)
- No effective antidote for some types
- Place only in areas livestock cannot access
- Consider alternative control methods
- Never use in or near feed storage
Medicated Feeds
- Clear labeling
