Peak-event data shows how higher throughput, seasonal staffing, and changing workloads can affect warehouse safety, while current industry data highlights the risks facilities manage throughout the year.
Peak periods can materially change warehouse operating conditions. Higher order volumes, longer shifts, rapid onboarding, and increased material movement can place additional demands on existing safety programs. A SOC analysis of OSHA-released Amazon records found serious injury counts increased by as much as 59% around major 2023 sales and holiday periods. These figures are specific to Amazon and should not be interpreted as an industry-wide peak-season injury rate.
Across the broader industry, the latest BLS data shows that warehousing and storage recorded 4.8 nonfatal occupational injury and illness cases per 100 full-time workers in 2024. For facilities preparing for demand surges, warehouse safety intelligence can complement established safety processes by continuously surfacing supported risks involving ergonomics, powered industrial trucks, PPE, pedestrians, and workplace conditions.
Amazon averaged 691 serious injuries per week across the facilities included in the SOC analysis during 2023. The report defines serious injuries as cases involving days away from work or job restriction, providing a baseline for comparison with major sales-event weeks.
During the week containing Amazon’s July 11–12 Prime Day event, the company recorded 1,066 serious injuries. It was the highest weekly total identified in the SOC analysis of Amazon’s 2023 injury records.
The 1,066 serious injuries recorded during Prime Day week represented a 48% weekly increase from the 721 injuries recorded during the preceding week, illustrating how quickly injury counts changed during a major peak event.
During the week containing Amazon’s October Prime Big Deal Days event, serious injuries increased from 655 to 898, a 37% week-over-week increase. Peak-related increases therefore occurred outside the traditional year-end holiday period as well.
Amazon recorded 1,015 serious injuries during the week beginning November 26, 2023. The total was 59% above the level recorded at the beginning of the holiday shopping period, and weekly injury counts remained above Amazon’s annual average until mid-December.
During the weeks containing Prime Day and Cyber Monday, Amazon accounted for nearly two-thirds of serious injuries identified across the U.S. warehousing industry in the SOC analysis. The figure is specific to the report’s dataset and methodology rather than the warehouse sector as a whole.
Higher throughput can increase repetitive handling, lifting, bending, reaching, and material movement. A Sentry claims analysis of 22,637 retail and wholesale injuries provides additional context on common injury patterns. These figures describe Sentry’s customer claims sample rather than all U.S. warehouses.
Internal Amazon information reviewed in a Senate HELP Committee Majority staff investigation showed a recordable injury rate exceeding 10 injuries per 100 workers during Prime Day 2019.
The same internal Amazon data placed the company’s total injury rate at just under 45 injuries per 100 workers during Prime Day 2019. This broader measure included cases beyond those required to be recorded under OSHA recordkeeping rules.
Strains accounted for 27% of injuries in Sentry’s retail and wholesale claims analysis, making them the most common injury type in the dataset.
Strain caused by lifting represented 11% of claims, the largest individual cause identified in Sentry’s analysis. Voxel’s ergonomic monitoring can provide continuous visibility into supported conditions such as improper bending, unsafe lifting, overreaching, and high-strain postures.
The lower back accounted for 10% of injuries by affected body part in Sentry’s claims sample. Fingers and multiple body parts each represented 11%.
Peak demand often requires facilities to onboard workers quickly while maintaining consistent training, supervision, and safe operating procedures.
Sentry found that 38% of injuries in its retail and wholesale claims sample involved employees in their first year with the company, regardless of age. Workers with one to five years of tenure represented another 28%.
Employees younger than 30 represented 32% of injuries in Sentry’s sample. Workers aged 51 to 65 represented another 26%, reinforcing the importance of matching training and controls to job demands rather than relying on age alone.
Among the claims that resulted in time away from work, employees missed an average of 70 workdays. Lost work time can compound peak-season staffing challenges when facilities are already operating near capacity.
Internal Amazon documents reviewed by Senate HELP Committee Majority staff showed a 54.7% fill rate from the end of March through the beginning of May 2021 as the company prepared for Prime Day.
From the beginning of May through the end of June 2021, Amazon reached a 71.2% fill rate. The company’s internal document noted that gaps between staffing levels and targets created business impacts and risk to Prime Day.
A worker interviewed during the Senate investigation described a delivery station where daily package volume increased to 120,000 during peak periods from roughly 60,000 packages under normal conditions.
A volume increase of that scale can affect staging areas, pedestrian routes, material handling, ergonomics, staffing, and vehicle activity simultaneously. Voxel’s vehicle safety capabilities can add continuous visibility into supported conditions including powered industrial truck speeding, unsafe stops, and vehicle-pedestrian proximity.
Peak events occur against an already significant warehouse safety baseline. Current BLS statistics provide industry-wide context separate from the company-specific peak-event data.
U.S. warehousing and storage operations recorded 4.8 cases per 100 full-time workers in 2024. This is the total recordable injury and illness rate for NAICS 493.
Cases involving days away from work, job restriction, or job transfer occurred at a 4.1 DART rate per 100 full-time workers in 2024. The rate included 1.5 days-away cases and 2.6 job-transfer-or-restriction cases per 100 workers.
BLS recorded 32 fatal injuries in warehousing and storage during 2024, compared with 28 in 2023. Fatality counts and nonfatal injury rates represent different measures and should be evaluated separately.
The SOC analysis identified over 106,000 injuries classified as serious at Amazon between 2021 and 2023. Those cases resulted in more than 6.1 million days away from workers’ regular job assignments.
The share of Amazon serious-injury cases resulting in light-duty assignments increased from 20% to 83% between 2018 and 2023. The comparable share at non-Amazon facilities in the analysis was 47% in 2023.
Amazon employees with serious injuries classified as light duty spent an average of 56 days away from their regular job assignments in 2023. Comparable light-duty cases at non-Amazon warehouses averaged 37 days.
The SOC analysis calculated that Amazon employed approximately 35% of workers represented in U.S. warehousing data in 2023 while accounting for 53% of serious injuries. The comparison is specific to the report’s methodology and should not be interpreted as a peak-season industry statistic.
Forklifts and other powered industrial trucks were involved in 84 worker deaths across U.S. workplaces in 2024, according to OSHA. Warehouses are only one environment where powered industrial trucks operate, but the figure reinforces the importance of training, pedestrian separation, traffic management, and equipment safeguards.
Peak periods can change warehouse conditions faster than periodic audits or manual observation alone can capture. Strong programs combine training, traffic management, equipment safeguards, inspections, ergonomics, employee participation, and corrective action with technologies that provide additional visibility.
Voxel’s industrial intelligence platform uses compatible existing cameras to continuously analyze supported conditions involving people, vehicles, equipment, and workplace environments.
Key capabilities for peak operations include:
Americold, a major temperature-controlled warehousing provider, achieved a 70% reduction in injuries, a 100% reduction in lost-time days, and $1.1 million in EBITDA savings at the featured facility during a 12-month safety transformation.
MSI results include a 50% reduction in lost-time injuries and a 73% reduction in workers’ compensation costs within six months at its Orange, California facility before Voxel expanded to four additional MSI locations.
These results highlight the measurable impact Voxel customers have achieved across warehouse and distribution environments, with outcomes reflecting each facility’s baseline conditions, safety priorities, and implementation approach.
Voxel works with existing IP cameras and can deploy to a site in 48 hours. Compatible facilities can therefore build additional safety and operational visibility on cameras already covering loading areas, aisles, material-handling zones, storage areas, and other locations.
Voxel is deployed at more than 250 sites worldwide and combines computer vision with expert-backed implementation across safety, risk, and operations.
Voxel does not use facial recognition and provides face and body blurring. Role-based access controls, SSO, encryption, and other enterprise safeguards support privacy-conscious deployment across permanent, seasonal, temporary, and unionized workforces.
The emphasis remains on identifying site-related risk patterns and helping teams improve workplace conditions rather than identifying individual workers.

There is no authoritative industry-wide percentage showing that injuries increase by a fixed amount across every warehouse during peak season. Company-specific data does demonstrate substantial increases can occur. Amazon’s serious injury count was 59% higher during Cyber Monday week in 2023 than at the beginning of its holiday shopping period.
Higher throughput can increase interactions among workers, powered industrial trucks, packages, pallets, staging areas, loading docks, and storage zones. Important priorities can include ergonomics, material handling, PIT-pedestrian separation, stopping behavior, PPE, clear aisles and exits, equipment condition, and new-worker onboarding.
Voxel continuously analyzes compatible camera feeds for supported conditions involving ergonomics, PPE, vehicles, pedestrians, equipment, and workplace areas. The platform organizes those observations into trends and connects relevant insights with corrective actions, ownership, deadlines, follow-up, and coaching.
Yes. Voxel works with over 95% of existing IP cameras and can deploy to a site in 48 hours using existing camera infrastructure. Camera placement, field of view, lighting, visibility, and the intended use case remain important when determining effective coverage.
Americold achieved a 70% reduction in injuries, a 100% reduction in lost-time days, and $1.1 million in EBITDA savings at the featured cold-storage facility. MSI achieved a 50% reduction in lost-time injuries and a 73% reduction in workers’ compensation costs within six months at its Orange facility before expanding Voxel to additional locations. These results demonstrate how Voxel customers have used industrial intelligence to strengthen existing safety programs while improving visibility into warehouse operations.
