Keeping a Texas warehouse staffed through the summer starts with planning for heat. Seasonal hiring between June and September brings in workers who have not yet adjusted to the conditions, and OSHA treats new and returning workers as the highest-risk group.
That is why heat coverage belongs in the temporary staffing plan for the season.
Where a Texas Warehouse Gets Hot
Heat inside a warehouse and distribution building varies by location, and the office thermostat does not reflect conditions across the warehouse floor. Open dock doors expose loading areas to outdoor air, so those zones track closer to the outside temperature while interior storage areas heat more slowly.
A lightly insulated metal roof absorbs heat through the day and radiates it downward into the building, which raises temperatures around the higher storage racks during afternoon shifts. A worker pulling inventory from the top of a rack at 3 p.m. can be working in noticeably more heat than someone at a packing bench in the middle of the building.
Over 2021 and 2022 combined, the Bureau of Labor Statistics recorded 1,420 heat exposure injuries in trade, transportation, and utilities that cost at least one day away from work, plus 980 in manufacturing. Those counts include only injuries that caused a missed workday, so the full number of heat-related incidents is higher.
What OSHA Requires in Texas Right Now
No final federal heat standard exists. OSHA proposed one in 2024 and the rulemaking is not finished, so heat hazards are cited under the General Duty Clause, the part of the law that requires employers to protect workers from known serious hazards.
OSHA issued directive CPL 03-00-024 effective April 10, 2026, running through April 2031 and replacing the 2022 program. It sets a national heat inspection focus, a forecast heat index of 80 degrees or more creates a heat priority day, and the national emphasis program covers indoor work as well as outdoor.
Texas does not set heat-specific break intervals, so OSHA evaluates how an employer’s heat program addresses conditions at the worksite. The directive spells out what a compliance officer records, which doubles as a self-audit list. Officers note the day’s heat index, National Weather Service alerts, and in some cases wet-bulb globe temperature, a stress measure that factors in humidity and radiant heat along with air temperature. They also document heat sources, PPE, and work intensity, check OSHA 300 and 301 logs for heat-related entries, and interview workers about headache, dizziness, fainting, and dehydration.
Employers are expected to train workers to recognize symptoms, provide water within easy reach, and give people a shaded or cooled place to recover during rest breaks. New and returning workers need time to adjust to the heat gradually, and someone should be watching whether the workload matches conditions as the shift progresses. How these expectations apply to your specific site is worth reviewing with your own safety and legal advisors.
Heat Turnover Is a Staffing Cost
When a worker overheats in week one and does not return, recruiting, screening, and orientation start again for that position, so one shift takes two hiring cycles to fill.
Attendance changes during the hottest weeks, and that becomes a larger coverage problem when it coincides with high outbound volume. Comparing no-call, no-show rates against the daily heat index for the local labor market shows which shifts need schedule changes. The pattern often concentrates on one shift or one part of a building, which is where a schedule change or an added water station helps most.
Build Acclimatization Into the First Week
OSHA and NIOSH recommend the 20% rule, which starts new workers at about one fifth of normal heat exposure. On an eight-hour shift, OSHA puts day one at roughly one hour and 40 minutes in the heat. Exposure then increases by about 20% each day across the first week. Keeping the work the same while reducing the hours builds tolerance for the specific job.
Apply the same schedule to experienced workers returning after time away, since acclimatization fades during an absence such as time off, an illness, or a plant shutdown. A distribution center scaling from 40 to 160 workers can protect fill rates by staggering new-hire start groups across two or three weeks rather than assigning all 120 to full shifts in week one.
Water, Breaks, and Supervisor Response
Place water within a short walking distance of active work zones. A station at the entrance can be out of reach for someone in the back half of a 400,000-square-foot building on a 15-minute break, and stations need to move as the work moves. OSHA recommends regular hydration reminders, because thirst is a late sign of dehydration, and supervisors should repeat those reminders through the shift.
Review station capacity before a large start group arrives. A shortfall appears as lines, shortened breaks, and workers who stop asking for access. The same capacity question applies to seating in cooled recovery areas. OSHA expects that area to sit away from heat sources such as ovens and furnaces, and it expects break length and frequency to increase as heat stress rises.
Train supervisors to treat rest requests as expected and to follow a defined response for reported symptoms. Where a lead treats a rest request as a productivity problem, workers stop reporting symptoms.
Align Your Staffing Partner With Your Heat Plan
Share your site heat procedures with the staffing agency before summer so workers receive site-specific guidance during orientation. Cover work zones, water stations, break structure, and first-week schedules, and put in writing how safety responsibilities are divided between the agency and the site.
