You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.236.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 06:21, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

((Short description|Clothing worn to protect a person in a hostile environment))((More citations needed|date=May 2008))
[[Image:Russian space suit 3.jpg|thumb|200px|Soviet space suit]]

An '''environmental suit''' is a [[wikt:suit|suit]] designed specifically for a particular environment, usually one otherwise hostile to humans. An environment suit is typically a one-piece garment, and many types also feature a [[helmet]] or other covering for the head. Where the surrounding environment is especially dangerous the suit is completely [[seal (mechanical)|sealed]].

The first environmental suits were [[diving suit]]s designed to protect a [[underwater diving|diver]] from the surrounding water (see [[timeline of underwater technology]]). Later developments were designed to protect the wearer from the cold (for example wetsuits and other ambient pressure suits) or from undersea high [[fluid pressure|pressure]] and the resulting [[decompression sickness]] (for example [[atmospheric diving suit]]s). Protecting the wearer from cold is also a feature of [[ski suit]]s.

In [[aviation]], [[pressure suit]]s protect [[fighter aircraft|fighter]] [[aviator|pilot]]s from [[hypoxia (medical)|hypoxia]] / [[altitude sickness]], and [[g-suit]]s from the adverse effects of acceleration (gravity-induced loss of consciousness, or [[G-LOC]]). The most extreme environmental suits are used by [[astronaut]]s to protect them during ascent and while in the vacuum of space: [[space suit]]s and [[space activity suit]]s. Such suits are self-supporting, and include a supply of [[oxygen]] for the wearer.

Environmental suits are also used to protect the wearer from contamination (for example [[hazmat suit]]s), or conversely to protect the environment from contamination by the wearer (see [[cleanroom suit]]s). The concept of an environmental suit protecting someone from contamination is a feature of the [[bubble boy disease|boy in the bubble]] trope: both [[David Vetter]] and [[Ted DeVita]] at some point used such suits.
