Postal Service’s Adverse Weather Condition Procedures

Every year, U.S. Postal Service employees risk illness and injury while working in extreme hot or cold temperatures. Mail carriers, especially, experience daily weather challenges and when exposed to extreme heat may be at risk of heat stress. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes. Employees can also face cold stress while performing their daily duties in cold environments, which can potentially lead to frostbite or hypothermia. Employers must take steps to prevent illnesses, injuries, or fatalities by controlling these hazards in workplaces impacted by extreme temperatures.
