In Europe, the use of panic bars is generally confined to code required applications. In US and
Canadian commercial buildings, they are frequently used even where not required by code, because bars are seen as being easier to use than knobs or lever handles. For example, when used on the rear service

However, EN 179 devices shall only be used at locations where people "are familiar with the emergency exit and its hardware and therefore a panic situation is unlikely to appear". Examples of places where EN 179 hardware may be used in place of EN 1125 panic bars include small apartment buildings and

In 2008, the standard was updated to include an alpha-numeric labelling scheme. In this system, products are tested to various benchmarks and assigned a letter or number accordingly. Products must achieve minimum quality scores in order to receive general CE approval. The nine rating categories are:

In some applications, such as storefront entrances, panic bars may be dogged during business hours. Dogging is a common feature on panic bars in which the bar is retracted with a key—freeing the door to swing without latching. This allows customers to apply force to any portion of the door, not just

Center posts are an alternative to vertical rods at double door exits. This offers less clearance because the post remains in the middle when both doors are open. That said, the post can often be removed with a key for occasions when items larger than a single door need to pass through. Center posts

In the event emergency exits are required, the crash bar works efficiently to allow people to pass through security doors without a reduction in speed. A crash bar's fast-acting mechanism reduces the risk that a rushing crowd might suddenly become a logjam at the exits. Such a human crush, which has

Some manufacturers offer crash bars designed to resist microbial growth. This can include coating the bar with silver ions in order to create a chemical environment hostile to unwanted microbes. Antimicrobial surfaces have shown to be effective at inhibiting bacterial, mold, and mildew growth; but

Crash bars are typically found on doors which are required emergency exits serving a particular type or quantity of occupants. Common locations include doors which provide egress from assembly areas, doors which serve many occupants, or doors serving hazardous areas. For buildings subject to the

441:
In Europe, most panic bars are of the cross bar type, which are called Type A in the EN 1125 standard. This contrasts strongly with North
American architectural design, which years ago switched to using predominantly touch bars (EN 1125 Type B) in new construction.

Vertical rods can be affixed to crash bars allowing both doors to be opened with no center clearance obstruction. When the bar is depressed, a chord within the vertical rod gets pulled, which lowers a latch at the top and/or bottom and allows the door to open. The

Push bars themselves are some of the most reliable door opening mechanisms. To pass CE certification, bars must function between 100,000 and 500,000 opening cycles depending on the rating the manufacturer is seeking.
