Poistoaika

Poistoaika is a Finnish term meaning “removal time” and is used to describe the duration required to remove something from a system, object, or environment. The exact meaning is field-dependent, but it generally refers to the time from the initiation of a removal action to its completion, and in many contexts may include preparatory steps and verification.

Common contexts include dentistry and medicine, where poistoaika can describe the time needed to perform an extraction or to remove a device or material; in industrial maintenance and manufacturing, where it denotes the time required to disassemble or purge a component, substance, or contaminant from equipment; and in environmental cleanup or decontamination, where it indicates how long a removal process lasts.

Estimating poistoaika depends on several factors, such as accessibility, safety requirements, the physical properties of the item being removed, the tools and technologies used, and the skill and procedures of the operator. It is typically estimated in planning stages, but actual durations are measured during execution to inform schedules and downtime planning.

In practice, poistoaika is used in project plans, procedure manuals, and maintenance schedules to communicate expected downtime and labor needs. Because the term is generic, field-specific definitions and conventions are common, and organizations often document their own standards for what is included in the measured time.
