Suojaasuissa

Suojaasuissa is a Finnish term that translates to "protective suits" and refers to garments designed to shield the wearer from hazardous environments or substances. The compound comes from suoj- meaning protection and -asu meaning outfit or clothes. The term is used to describe a range of clothing designed to reduce exposure to chemicals, biological agents, contaminants, or extreme conditions.

Protective suits are used across industries such as healthcare, chemical processing, construction, emergency response, and military contexts. They vary in material, sealing, and level of protection, from disposable coveralls to fully encapsulated hazmat suits. Types are generally grouped by the hazard: liquid and chemical protection, airborne or biological protection, heat and flame resistance, and radiological or nuclear protection. Some suits are gas-tight and designed for use with breathing apparatus; others are impervious but not gas-tight.

Materials used for protective suits include high-density polyethylene fibers (for example Tyvek), laminated films, butyl rubber, neoprene, and multi-layer composites. Design features can include taped seams, elastic cuffs, integrated hoods, booties, and, in more advanced models, powered air-purifying systems. Proper donning and doffing procedures are critical to prevent contamination.

Regulatory oversight comes from national occupational safety agencies and international standards bodies. In Europe, protective clothing is governed by CE marking and standards set by CEN and ISO, covering chemical, biological, fire, and heat-protective performances. The development of protective suits has historical roots in industrial hygiene, chemical processing, space exploration, and medical fields, leading to specialized forms for HazMat response and cleanroom applications. In Finland and other countries, employers provide protective suits as part of risk management and training on proper use and disposal.
