Week 3 of National Safety Month: Heat-Related Illness

Every year, workers in agriculture and other industries become ill due to exposure to high temperatures. Some of these injuries, unfortunately, also become fatalities. As temperatures increase, it is important to take precautions to prevent heat illness. Following guidelines created by Cal/OSHA and other safety professionals will help workers from experiencing heat illness.

Workers should be trained to recognize the signs and symptoms of heat illness and take appropriate action to protect themselves and their coworkers. Some common symptoms of heat illness include:

  • Heat cramps: muscle cramps and spasms, usually in the legs or abdomen, that occurred during or after physical activity in hot weather.
  • Heat exhaustion: weakness, dizziness, nausea, headache, sweating and cool, moist skin can be precursors to heat stroke if not treated properly.
  • Heat stroke: life threatening emergency that occurs when a body’s temperature regulation system fails. Symptoms include high body temperature above 103°F, confusion, agitation, seizures and loss of consciousness. Heat stroke requires immediate medical attention.

As part of a safety plan, employers should have a written program to address heat illness prevention that addresses critical factors, including:

  • Appropriate steps to take when temperatures reach certain critical thresholds.
  • Procedures for providing sufficient, potable water that is easily accessible to employees.
  • Procedures for providing access to shade or other appropriate cool-down areas.
  • Appropriate emergency response actions that should be taken if an employee is demonstrating signs or symptoms of heat-related illness.
  • Methods and procedures to assist workers, especially new workers, in acclimatizing to warm environments should be included in standard practices.

Employee safety training, including heat illness prevention training, is available through Western Growers Insurance Services.
