What is the best professional thermal clothing for working in extreme cold environments such as cold storage rooms and low-temperature workplaces?

Working in cold conditions, whether extreme cold in cold storage chambers or in areas with cold ambient temperatures ranging from 0 to 5 ºC, requires clothing specifically designed to maintain body temperature and ensure worker comfort and safety throughout the working day.

Previously, we analyzed the key factors for choosing the best safety footwear for extreme cold and humid conditions. On this occasion, we focus on professional thermal clothing, an essential element that completes worker protection in environments where the ambient temperature is cold and/or the cold is extreme, and where, in many cases, lighting or visibility is also limited.

In these scenarios, the incorporation of high-visibility details is essential to enhance safety.

Below, we detail the key characteristics of professional thermal clothing, the standards it must meet and the most recommended garments for work in extreme cold.

What should be considered when choosing thermal clothing for working in extreme cold?

To ensure safety and comfort in extremely cold working environments, professional thermal clothing must meet a series of characteristics that guarantee protection, functionality and comfort throughout the working day.

• Good breathability
  It is essential that fabrics allow moisture generated by the body to evaporate. Materials such as polyester or cotton blends help keep the skin dry, preventing the feeling of cold caused by sweat accumulation.
• High thermal insulation capacity
  Clothing must provide effective insulation to retain body heat even at very low temperatures, such as those found in cold storage chambers, where temperatures can reach down to -40 ºC or -50 ºC.
• Comfort and freedom of movement
  Ergonomic design is essential, with suitable cuts, adjustable waistbands or suspenders in the case of bib trousers, allowing tasks to be performed with full mobility without compromising thermal protection.
• Resistance and reinforcements in key areas
  Garments intended for intensive use must incorporate reinforcements in areas such as shoulders, elbows or knees, increasing durability and resistance to continuous wear.
• Protection against thermal changes
  These garments should include padded inner linings that help minimize heat loss during sudden temperature changes, such as when entering or exiting cold storage chambers.
• High-visibility elements
  For outdoor work or environments with reduced lighting, reflective or high-visibility details are essential to improve worker detection and enhance safety.
• Practical and functional pockets
  Well-distributed pockets allow tools, mobile devices or other work utensils to be carried without affecting insulation or garment comfort.

What standards must thermal protective garments for extreme cold comply with?

Professional clothing intended for working in extreme cold conditions and cold storage chambers must comply with a series of standards that guarantee thermal insulation, safety and, in certain environments, high visibility.

• EN ISO 13688:2013 – Protective clothing. General requirements:
  It does not define a specific type of protection, but establishes general requirements for protective clothing in terms of ergonomics, sizing and fit, harmlessness, comfort and breathability, marking and labeling, resistance and durability (seams, material strength, etc.). It is always used in combination with other specific standards, in the case of cold protection clothing with EN 342 and in the case of high visibility for high risk EN ISO 20471 and for medium risk EN 17353.
• EN 342:2017 – Protective clothing against cold:
  Regulates ensembles and garments designed for temperatures below -5 ºC, typical of extreme cold or cold storage chambers. The following categories are distinguished:
  • Category I: protection against temperatures above -5 ºC (UNE-EN 14058:2004).
  • Category II: protection against temperatures between -5 ºC and -50 ºC (UNE-EN 342:2004).
  • Category III: garments intended for temperatures equal to or below -50 ºC.
• EN 17353 – High-visibility clothing:
  Applied to garments designed to improve user visibility in daylight conditions through fluorescent material.

Compliance with these standards ensures that thermal clothing has been designed to provide protection, insulation and comfort in demanding industrial environments.
