People caught in very cold, snowy conditions can build an igloo or snow cave to shelter. [58] [59] The United States Coast Guard promotes using life vests to protect against hypothermia through the 50/50/50 rule: If someone is in 10 °C (50 °F) water for 50 minutes, they have a 50 percent better chance of survival if they are wearing a life ...
Gas leaks can damage or kill plants. [4] [5] In addition to leaks from natural gas pipes, methane and other gases migrating from landfill garbage disposal sites can also cause chlorosis and necrosis in grass, weeds, or trees. [6] In some cases, leaking gas may migrate as far as 100 feet (30 m) from the source of the leak to an affected tree. [7]

Sufficient stress from extreme external temperature may cause injury or death if it exceeds the ability of the body to thermoregulate. Hypothermia can set in when the core temperature drops to 35 °C (95 °F). [2] Hyperthermia can set in when the core body temperature rises above 37.5–38.3 °C (99.5–100.9 °F).
Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane
The patient may report feeling cold, followed by mild chills, cold skin, moderate pallor, tachycardia, hypertension, tremor, or piloerection. External warming techniques are advised to prevent hypothermia. [citation needed] Among the frequently altered functions is the cardio-circulatory.
