Personal protective equipments
LNG is extremely cold, which makes it a cryogenic liquid. Generally, substances which have boiling points below -150°C (- 238°F) or less are considered cryogenic and require special technologies for handling. The cryogenic temperature of LNG means it will freeze any organic tissue (plant or animal) upon contact; the resulting injury would be similar to a high-temperature wound and is often referred to as a “cold burn”. Cold burns may occur in the event that skin comes in direct contact with LNG itself or through contact with the equipment/hose lines that have been super-cooled during an LNG operation/activity (evidenced by frosting). Personal Protective Equipment (PPE) designed for protection against cryogenic liquids must be worn at all times when working with LNG. As it is specified in the relevant EU norms, or in NFPA 52-2013, protective clothing, goggles and gloves shall be provided for all operators dispensing and handling LNG. Shall be permitted to be excluded where equipment is demonstrated to operate without exposing operators to release of LNG.
