With the northeast already hit with its first snowstorm, it's time to review cold weather protection basics.
Prolonged exposure to freezing or cold temperatures may cause serious health problems such as trench foot, frostbite and hypothermia, according to OSHA. In extreme cases, including cold water immersion, exposure can lead to death. Danger signs include uncontrolled shivering, slurred speech, clumsy movements, fatigue and confused behavior. If these signs are observed, call for emergency help, OSHA says.
