Cold injuries may be general (hypothermia) or local (freezing cold injury [FCI] and non-freezing cold injury [NFCI]). Irreversible FCI is termed frostbite, reversible FCI is termed frostnip, the latter may still have long-term sequelae including dysesthesias. The severity of injury, and the degree of irreversible tissue necrosis, is directly proportional to both the temperature and duration of exposure, and is influenced by the area of tissue exposed. Poorer outcomes are seen in lower extremity involvement, concomitant infection, and delayed injury presentation. NFCI, or ‘trench-foot’ is due to prolonged exposure to sub-physiological temperatures that do not lead to tissues freezing.

Local cold injury may be classified as: Freezing cold injury (FCI) due to sub-zero TA and high VA, ranges from superficial/reversible frostnip to frostbite.Non-freezing cold injury (NFCI) due to prolonged exposure to cold and wet/damp conditions.

A major increase (15%) in emergency room visits by workers for cold-related injuries such as slips and falls (CP11) has been observed with every degree that the temperature falls during cold weather, and an increase in wind speed further increases the number of visits by 6% [49,50,51]. The rising number of slips, trips and fall-related accidents is attributed to ice, snow, limited visibility and cooling of the body [37,49]. Two-thirds of all fall events in cold weather occur on ice that is coated with snow [60]. Trench foot or immersion foot are also the result of working in cold environments [62,63]. Trench foot (CP12) is a condition in which blood vessels are inflamed to the extent that they damage organs and tissues; it is common among those who work for prolonged periods of time in temperatures that are above 0° C (32 °F). Immersion foot develops when workers stand in the same position for long periods of time, especially in cold, wet environments [61]. The terms trench foot and immersion foot are often used interchangeably; immersion foot, formerly known as trench foot, is considered a non-freezing cold injury. It is experienced by many outdoor workers, and often occurs when construction workers perform jobs, such as excavating a hole for a foundation, in cold, muddy water [63]. The symptoms of immersion foot begin with numbness and white or pale skin that changes to a shade of blue. It is often characterized by numbness and severe pain, even after heat has been restored [64,65]. Table 5 presents the physical challenges and health issues that workers encounter in extremely cold temperatures.
