Clearanceetäisyyksiin

Clearanceetäisyyksiin, or clearance distances, refer to minimum safe distances required between people, equipment, vehicles, or structures to prevent contact, allow safe operation, and provide sufficient working space. The concept emerges from risk assessment and safety standards and is applied across many industries to minimize injury and damage.

In traffic and transportation, clearance distances include the following distance kept behind another vehicle to allow for sudden braking and maneuvering. The exact distance depends on speed, weather, and vehicle type, with general guidelines such as a two-second rule that can be adjusted for circumstances. Adequate clearance is also considered in pedestrian zones, intersections, and during vehicle loading and unloading to avoid collisions.

In industrial and construction settings, clearance distances define exclusion zones around moving machinery, overhead loads, or hazardous areas. They help prevent contact with rotating parts, falling objects, or energized equipment and are enforced through barriers, signage, and procedures such as lockout/tagout and controlled access.

In aviation and maritime operations, clearance distances relate to obstacle clearance and safe separation from structures, other aircraft or vessels, and to maintain safe corridors and routes. These distances may be specified by regulatory authorities and facility-specific procedures to ensure operational safety.

Implementation relies on risk assessment, explicit rules, and training. Regular inspection, clear signage, physical barriers, and supervision help maintain clearance distances and reduce the likelihood of accidents.
