Frostbite is a cold related injury that occurs when body tissue is exposed to sufficiently low temperatures for long enough that the tissue begins to freeze.
It most commonly affects exposed areas such as the fingers, toes, ears, nose, cheeks and chin. Severe cold can cause ice crystals to form within and around cells, damaging tissue and reducing blood flow.
Frostbite should not be confused with simply feeling cold.
A person can work in a cold environment and experience discomfort, numbness or cold stress without necessarily developing frostbite. Frostbite occurs when the tissue itself becomes sufficiently cold that freezing injury develops.

The risk depends on several factors, including:
Yes, frostbite is possible in an ultra-cold storage environment.
The risk depends on the actual temperature and how long the person is exposed.
A conventional chilled cold room operating around +2°C to +8°C is not normally cold enough to freeze human tissue under ordinary circumstances. However, freezer rooms operating below 0°C present a progressively greater cold-injury risk.
Very low-temperature storage rooms and industrial freezers can create particularly hazardous conditions. A person working inside such an environment for an extended period may develop cold injury, especially if protective clothing is inadequate.
The situation becomes more serious when the storage temperature is far below the freezing point of water.

Frostbite is not determined by temperature alone.
For example, briefly entering a freezer room at a sub-zero temperature is not necessarily equivalent to spending a prolonged period working inside it. The colder the environment and the longer the exposure, the greater the potential for tissue injury.
Moisture can also increase the danger because wet skin loses heat rapidly.
Yes. A blast freezer can create conditions capable of causing frostbite.
Blast freezers are specifically designed to remove heat from products rapidly. Depending on the system and application, the air temperature can be substantially below 0°C.
The danger is not that the blast freezer automatically causes frostbite the instant a person enters it. Rather, the combination of very low temperature, exposure time and direct contact with extremely cold surfaces or products can cause cold injury.
A blast freezer can also have strong air circulation. Moving cold air can increase heat loss from exposed skin.
Personnel who must enter or work around low-temperature freezer environments should use appropriate cold-protection equipment and follow workplace safety procedures.
Protection may include:
Workers should not rely solely on ordinary clothing when working in extremely low-temperature environments.
Yes, direct contact with certain refrigerants can cause a frostbite-type cold injury.
This is different from simply being in a refrigerated room.
When a refrigerant is released from a pressurized system, the refrigerant can undergo rapid expansion and cooling. If liquid refrigerant or very cold refrigerant discharge contacts the skin, it can rapidly remove heat from the tissue.
This can cause cold burns or frostbite-like tissue injury.
The risk is particularly serious when refrigerant escapes through:
Refrigeration systems can contain refrigerant under pressure. When liquid refrigerant escapes into a lower-pressure environment, it can evaporate rapidly.
That phase change requires energy. Heat is taken from the surrounding environment, including the skin if direct contact occurs.
Consequently, a refrigerant leak can cause severe cold injury even though the person may only have been exposed for a short time.
Never deliberately place your hand near or directly into a refrigerant discharge to test whether a system is leaking.
Refrigerant exposure can also present other hazards depending on the refrigerant involved, including oxygen displacement, toxicity or decomposition products.
Yes. Dry ice can cause frostbite and severe cold injury.
Dry ice is solid carbon dioxide (CO₂) and has a temperature of approximately −78.5°C at atmospheric pressure.
That is far below the freezing point of water.
Directly holding dry ice with bare skin can rapidly remove heat from the skin and potentially cause a cold burn or frostbite.
The danger is not limited to prolonged contact. Direct contact with such an extremely cold material can cause injury relatively quickly.
Appropriate insulated gloves and suitable handling procedures should be used when handling dry ice.
Dry ice also creates a separate hazard because it changes directly from a solid into carbon dioxide gas. In poorly ventilated areas, carbon dioxide can accumulate and create an asphyxiation hazard.
Therefore, dry ice presents both:
Yes. Liquid nitrogen can cause severe cold injury, including frostbite.
Liquid nitrogen is extremely cold, with a boiling point of approximately −196°C at atmospheric pressure.
Direct skin exposure can cause rapid freezing injury.
Liquid nitrogen should therefore only be handled using appropriate equipment, procedures and training.
Protective measures may include suitable cryogenic gloves, eye and face protection, appropriate containers and adequate ventilation.
The temperature difference between liquid nitrogen and normal ice is enormous.
Ordinary ice is around the melting/freezing point of water, approximately 0°C, while liquid nitrogen is approximately −196°C at atmospheric pressure.
This is why direct contact with liquid nitrogen presents an extreme cryogenic hazard.
Liquid nitrogen can also rapidly expand into nitrogen gas. In an enclosed or poorly ventilated area, this can displace oxygen and create an oxygen-deficiency hazard.
Yes, but the circumstances are important.
Ordinary ice is approximately 0°C when it is at its melting point. Direct contact with ice for a prolonged period can cause cold injury, particularly when the skin is wet, pressure is applied or circulation is restricted.
However, the risk from ordinary ice blocks is generally very different from the risk associated with dry ice or liquid nitrogen.
A person briefly touching an ordinary ice block is not automatically going to develop frostbite.
The risk increases with:
For example, holding an ice block against bare skin for a prolonged period is substantially different from briefly touching it.
Frozen food can also be cold enough to cause a cold-contact injury under certain circumstances.
A frozen product may be below 0°C, and prolonged contact with bare skin can remove heat from the tissue.
This is particularly relevant to workers handling large quantities of frozen products in:
Using suitable gloves and minimizing unnecessary direct skin contact are important precautions.
The terms frostbite and cold burn are sometimes used interchangeably in everyday conversation, but the circumstances can differ.
Frostbite generally refers to tissue freezing caused by exposure to sufficiently cold conditions.
A cold burn or cryogenic burn can occur when extremely cold materials or substances, such as certain refrigerants, dry ice or liquid nitrogen, come into direct contact with tissue.
In practical workplace safety, both situations should be treated seriously because severe cold exposure can cause significant tissue damage.
The initial signs can include:
More severe injury may result in:
A person may not fully appreciate the severity of the injury because numbness can reduce pain sensation.
If frostbite or a serious cold injury is suspected, the person should be removed from the cold environment and protected from further exposure.
Do not aggressively rub or massage frozen or numb tissue. Do not use direct high heat, such as a flame, heating element or very hot water, because numb tissue can be burned easily.
Serious, extensive or deep cold injuries require prompt medical evaluation.
Particular caution is required after exposure to liquid refrigerant, dry ice or liquid nitrogen because the injury can be severe even when the affected area initially appears relatively small.
Not every cold environment presents the same frostbite risk.
| Exposure | Can Cause Frostbite/Cold Injury? | Main Concern |
|---|---|---|
| Chilled cold room (+2°C to +8°C) | Generally low frostbite risk | Cold stress and prolonged exposure |
| Freezer room below 0°C | Yes, depending on exposure | Prolonged cold exposure |
| Blast freezer | Yes | Very low temperatures and cold air |
| Frozen products | Yes, with prolonged contact | Direct cold contact |
| Ice blocks | Possible with prolonged contact | Direct contact and pressure |
| Refrigerant discharge | Yes | Rapid cooling and possible cryogenic injury |
| Dry ice (−78.5°C) | Yes | Severe direct-contact cold injury |
| Liquid nitrogen (−196°C) | Yes | Extreme cryogenic injury |
Frostbite is caused by sufficiently severe cold exposure that freezes or seriously damages body tissue.
A person does not have to be standing outside in a snowstorm to suffer a cold injury.
Industrial refrigeration environments can present cold-related hazards, particularly in blast freezers, low-temperature freezer rooms, refrigerated containers and cold-storage facilities.
Direct contact with extremely cold materials or substances can be even more dangerous. Dry ice, liquid nitrogen and certain refrigerant releases can cause severe cold injuries through direct contact.
Ice blocks can also cause cold injury when skin remains in prolonged contact with them, although ordinary ice is considerably warmer than dry ice or liquid nitrogen.
For refrigeration technicians, cold-room workers and anyone handling frozen products, the safest approach is to treat extremely cold equipment, products and substances as potential sources of cold injury and use appropriate personal protective equipment and safe work procedures.
