The Rutgers NJAES factsheet on “Preventing Heat Stress in Agriculture” has been updated and is now available at https://njaes.rutgers.edu/FS747/. The factsheet provides basic knowledge about heat stress, first-aid treatment, and preventative measures that are important to both agricultural employers and workers. As the temperatures warm up, it’s time to get prepared for working in the heat!
Several types of heat-related illnesses can affect workers and symptoms may be non-specific. When a worker is performing physical labor in warm environments, any unusual symptom may be a sign of heat illness. The chart below from OSHA outlines symptoms and signs that may indicate heat stress. Note that common signs and symptoms include muscle pain, weakness or fatigue, dizziness, heavy sweating, and rapid heart rate.

Employers and workers should become aware of symptoms related to heat stress and heat illness. In addition, knowing what to do when someone is showing signs of heat illness is very important. This resource from NIOSH describes the appropriate first aid for each of these illnesses. Prompt action to provide first aid can make a difference in recovery of persons with heat illness. Multiple heat-related illnesses can occur together, and time is of the essence.
When in doubt, place the worker in a cool environment and call 911.
The body uses water to help dissipate heat through sweat and evaporation of sweat. Water lost as sweat must be replaced through water consumption to help the body maintain temperature regulation. During moderate activity, the CDC recommends drinking at least 1 cup of water every 15-20 minutes to replace water lost through sweat.
Sports drinks are likely unnecessary to replenish the body’s electrolytes when adequate hydration is combined with regular meals. However, sports drinks may be beneficial to help balance the body’s water and electrolytes when tasks conducted under hot temperatures result in prolonged sweating over several hours.
Limit consumption of energy drinks, alcohol, and caffeine-containing beverages such as coffee, tea, and soda. These beverages can contribute to dehydration, increasing the risk of heat illness.
Staying hydrated starts before work then continues throughout the day and after work. Attention to personal hydration decreases the risk of heat illness and other risks associated with chronic dehydration, such as kidney stones.
The New Jersey Legislature is currently reviewing identical bills (A3521/S2422) which would establish an occupational heat stress standard and “Occupational Heat-Related Illness and Injury Prevention Program” under the NJ Department of Labor and Workforce Development. As we monitor the progress of these bills, the Farm Health and Safety Working Group of Rutgers Cooperative Extension has launched an educational program on heat stress mitigation in agriculture which includes weekly “Beat the Heat” articles published in the Rutgers Plant and Pest Advisory E-Newsletter, an update to the Rutgers factsheet “Preventing Heat Stress in Agriculture” and a webinar series.

Heat safety tool phone app created by OSHA and NIOSH.
As the weather warms up, prepare yourself to evaluate the heat risk for outdoor tasks. We often use a weather application on our phone to check the daily high and low temperature, but air temperature alone is not sufficient to evaluate heat risk. Heat index is a more appropriate measurement because it combines the effects of air temperature and humidity to indicate the level of discomfort felt by the average person.
One easy way to check the heat index is the Heat Safety Tool phone app (see photo) developed by the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH). The app calculates heat index at your specific site and displays the risk level to outdoor workers. It also provides insight into protective measures for the given risk level. This mobile phone app is available for both Android and iPhone.
A similar, web-based tool is the HeatRisk website created by the U.S. Centers for Disease Control and Prevention (CDC). The HeatRisk homepage has a color-coded map to indicate today’s heat risk (no risk to extreme risk) for each county in the U.S. You can also enter your zip code to get the daily and 5-day forecasted heat risk for your site plus corresponding actions to reduce heat-related health risks.
Stay tuned for weekly posts on how beat the heat this summer!
The nature of agricultural work demands farmers spend long hours outdoors in direct sunlight, which increases their risk of developing skin cancer. Prevalence of skin cancer among the agricultural community has prompted Rutgers Cooperative Extension and the Vegetable Growers Association of NJ to partner with ScreenNJ to offer no-cost skin cancer screenings to farmers who register for the convention and also sign up separately for this screening opportunity.
These screenings will take place at the upcoming New Jersey Agricultural Convention and Trade Show at Harrah’s Resort and Waterfront Conference Center located at 777 Harrah’s Blvd. in Atlantic City, New Jersey. Appointments for skin cancer screenings will be available on Wednesday, February 7, 2024, from 9 a.m. to 3 p.m. Screenings will take place in the ScreenNJ ‘LifeSaver’ Mobile Health Unit RV in the parking lot just outside the trade show.
Advanced registration before the convention is strongly recommended, as time slots are very limited. There may only be a few times available for same-day registration at the convention. Screening time is estimated to be 20 minutes per person, so please keep this in mind as you plan your trip to the convention. As a reminder, the agenda for the educational sessions at the convention and general registration information are available at https://vganj.com/registration. The skin cancer screening opportunity is a separate registration. Follow these steps to register in advance for a skin cancer screening at this event: ·
