Urban exploration
Encyclopedia
Urban exploration is the examination of the normally unseen or off-limits parts of urban areas or industrial facilities. Urban exploration is also commonly referred to as infiltration, although some people consider infiltration to be more closely associated with the exploration of active or inhabited sites. It may also be referred to as "draining" (when exploring drains) "urban spelunking", "urban caving", or "building hacking".

The nature of this activity presents various risks, including both physical danger and the possibility of arrest and punishment. Many, but not all, of the activities associated with urban exploration could be considered trespass

Trespass is an area of tort law broadly divided into three groups: trespass to the person, trespass to chattels and trespass to land.Trespass to the person, historically involved six separate trespasses: threats, assault, battery, wounding, mayhem, and maiming...

Targets of exploration

Urban explorers often attempt some or all of these subsets of urban exploration.

Another aspect of urban exploration is the practice of exploring active or in use buildings which includes gaining access to secured or "member-only" areas, mechanical rooms, roofs, elevator rooms, abandoned floors and other normally unseen parts of working buildings.

.

Steam tunnels, in general, have been secured heavily in recent years, due to their use for carrying network backbones and perceived risk of their use in terrorist activities, safety and liability.

Some steam tunnels have dirt floors, no efficient lighting and have temperatures upwards of 45 °C (113 °F). Others have concrete floors, bright light, and feature a cool low-grade temperature. Most steam tunnels have large intake fans to bring in fresh air and push the hot air out the back. Most active steam tunnels do not contain airborne asbestos but proper breathing protection may be required for other hazards. It is wise to take proper care inside active utility tunnels, since pipes can spew boiling hot water from leaky valves, puddles pool at your feet, and forceful steam may leak inward resulting in burns and slips.

Popularity

 have packaged the hobby for a popular audience. Talks and exhibits on urban exploration have appeared at the 5th and 6th Hackers on Planet Earth Conference, complementing numerous newspaper articles and interviews.

With the rise in the relative popularity of the hobby due to this increased focus, there has been increasing discussion on whether the extra attention has been beneficial to urban exploration as a whole. The unspoken rule of urban exploring is "take nothing but photographs, leave nothing but footprints", but because of the rising popularity, many individuals who may have other intentions are creating a concern among many property owners.

Safety and legality

Urban exploration is a hobby that comes with a number of inherent dangers. Storm water drains are not designed with human access as their primary use. They can be subject to flash flooding and bad air. There have been a number of deaths in storm water drains, but these are usually during floods, and are normally not Urban Explorers.
