Impairment detection technology in agriculture with AlertMeter®

Agriculture and related industries, including grain cooperatives, food and beverage processing, agronomy operations, and fuel and propane distribution, remain among the highest risk sectors in the United States. These workplaces expose workers to hazards involving heavy machinery, fast paced production environments, pressurized systems, flammable materials, rural road travel, and physically demanding work. In 2022, the agriculture, forestry, fishing, and hunting sector recorded a fatal injury rate of 18.6 deaths per 100,000 full time workers, compared to 3.7 per 100,000 across all industries.¹

Yet not all incidents are caused by equipment or environmental conditions. Many stem from human factors. Human impairment is not limited to drug or alcohol use - it can also result from fatigue or lack of sleep, illness, emotional stress, medication effects, dehydration, or mental overload. These conditions reduce alertness, slow reaction time, and impair decision making. Fatigue is known to diminish attention and increase the likelihood of errors.² As operations modernize their safety programs, impairment detection technology has emerged as a practical, proactive tool for reducing preventable incidents.

Why impairment detection matters for workplace safety

Impairment detection refers to tools and methods that identify when a worker’s alertness or cognitive readiness is reduced, regardless of the cause. Workers across agricultural, food processing, and fuel distribution operations routinely face conditions that contribute to fatigue or cognitive overload, including:

• Early mornings, long shifts, and extended seasonal workloads
• Repetitive or high speed tasks requiring sustained attention
• Operation of heavy equipment or commercial vehicles
• Exposure to heat, noise, vibration or weather-related stress

Traditional safety programs cannot easily determine whether a worker is fully alert and ready for high risk tasks. Objective alertness testing tools like Predictive Safety’s AlertMeter® help close that gap by providing a real time measure of cognitive readiness.³

How AlertMeter works

AlertMeter is a 45–60 second cognitive test that compares a worker’s performance to their own established baseline to identify reduced alertness.

• Workers build a personal baseline through a few initial tests.
• Before a shift, they complete a quick shape matching test on any touchscreen device.
• The system measures reaction time and consistency and flags scores outside the worker’s normal range.
• Supervisors receive real time alerts when a check in is needed before assigning safety sensitive work.

Roles that could benefit from impairment detection

Impairment detection is especially valuable for workers performing safety‑sensitive tasks where even a brief lapse in alertness can lead to serious incidents.

• Delivery drivers hauling propane, fuel oil, or refined products
• Drivers navigating rural or high‑traffic delivery routes
• Service technicians working on pressurized tank systems
• Workers conducting leak checks, pressure tests or confined‑space activities

• Grain elevator and feed mill operators
• Forklift operators in warehouses or ingredient storage
• Those working around engulfment hazards or moving mechanical equipment
• Tender‑truck drivers and agronomy applicator

• Tractor, combine and sprayer operators
• Seasonal laborers working long shifts during planting and harvest
• Workers involved in roadway travel, hauling equipment or operating heavy machinery

• High‑speed production line operators
• Sanitation crews working overnight or irregular hours
• Quality assurance workers performing repetitive, high‑attention tasks
• Maintenance technicians servicing automated equipment

Across these roles, impairment detection provides a meaningful safety checkpoint, supporting decisions that protect both workers and operations.

Building stronger, safer operations

Whether in a grain elevator, a bottling line, or a cornfield, impairment detection gives leaders a proactive way to strengthen their safety culture and reduce preventable incidents. With technology like AlertMeter®, employers gain a real-time insight into worker readiness, helping them make informed decisions, keep workers safe and maintain operational efficiency.
