As summer temperatures rise, so do the risks for heat-related illnesses—especially for workers in the material handling and warehouse industries, where physical exertion and limited airflow are part of the daily routine. Whether employees are loading trucks outdoors, managing logistics in open-air yards, or working in non-climate-controlled warehouses, staying cool isn’t just a matter of comfort—it’s a matter of safety. Employers have a responsibility to protect their teams from heat stress and related hazards. This article offers practical, proven tips to help keep your workforce safe, cool, and productive throughout the hottest months of the year.

1. Hydration Strategies

• Water stations: Place multiple shaded water stations with coolers or dispensers filled with ice water.

• Electrolyte options: Offer sports drinks or electrolyte powders to replenish salts lost through sweat.

• Hydration reminders: Use signs, mobile app reminders, or supervisors to prompt workers to drink water every 15–20 minutes.

2. Shade & Rest Breaks

• Pop-up tents or canopies: Provide shaded areas at regular intervals.

• Portable misting tents or fans: Use cooling fans or misting systems in rest areas.

• Mandatory cool-down breaks: Schedule 5–10 minute breaks in the shade every hour, more frequently if temps are above 90°F.

3. Clothing & Gear

• Lightweight, breathable fabrics: Encourage moisture-wicking clothing in light colors.

• Cooling gear:

  • Cooling vests (ice-pack or evaporative)

  • Neck wraps or towels soaked in cold water

  • Wide-brimmed hats or brim extensions on helmets for sun protection

• UV-protective gear to prevent sunburn and overheating.

4. Work Schedule Adjustments

• Start earlier or split shifts: Begin work at sunrise and pause during peak heat hours (typically 12–4 p.m.).

• Rotate tasks: Alternate between physically intense and less demanding tasks.

• Use buddy systems to monitor for signs of heat illness.

5. Cooling Equipment

• Battery-operated fans: Personal wearable fans for hard-to-reach sites.

• Portable misting fans: For job trailers or staging areas.

• Ice chest/coolers: Keep cold towels or drinks handy.

6. Training & Awareness

• Heat illness prevention training:

  • Teach symptoms of heat exhaustion and heat stroke.

  • Emphasize the importance of acclimatization.

• Post safety signs in common areas with visual cues for heat illness symptoms and first aid steps.

7. Technology Solutions

• Wearable sensors: Monitor core body temp or heart rate (ideal for high-risk environments).

• Weather alert apps: Notify crews when heat advisories are issued.

8. Environmental Enhancements

• Temporary shade structures near worksites.

• Pavement wetting (for road crews) to reduce ambient surface temperature.

• Tree planting (long-term) or use of artificial vertical shade barriers where possible.

Pro Tips

• Use OSHA’s Heat Safety Tool app for personalized alerts and recommendations.

• Gradually acclimate new or returning workers to heat over 1–2 weeks.

• Create a heat emergency response plan, including access to cold packs, cooling areas, and emergency contact protocols.
