Pointing and calling

Pointing and calling is a method in <a href="/facts/Occupational_safety/ko1IeS92">occupational safety</a> for avoiding mistakes by pointing at important indicators and verbally calling out their status. It is especially common on <a href="/facts/Rail_transport_in_Japan/fzp5qyYg">Japanese railways</a>, where it is referred to as shisa kanko (指差喚呼), shisa kakunin kanko (指差確認喚呼) or yubisashi koshō (指差呼称); in <a href="/facts/Rail_transport_in_China/94yaP4mJ">Mainland Chinese</a> and <a href="/facts/Rail_transport_in_Taiwan/SNEVKC89">Taiwanese railways</a>, where it is called 指差呼唤; 指差確認 (zhǐchā hūhuàn); and in <a href="/facts/Rail_transport_in_Indonesia/2Id4gGKS">Indonesian railways</a>, where it is known as tunjuk-sebut. Gesturing at and verbalizing these indicators helps with focus. The method was first used by train drivers and is now commonly used in Japanese industry. It is recommended by the Japan Industrial Safety and Health Association [ja] (JISHA, 中央労働災害防止協会), and a part of railway management regulations in China. It is not common outside of Asia, though it is used in the <a href="/facts/New_York_City_Subway/1NKtIgLr">New York City Subway</a> system, Toronto's <a href="/facts/Toronto_subway/AN0MPLkv">TTC subway</a> and <a href="/facts/GO_Transit_rail_services/EGjdHeT4">GO Transit</a> and many systems built to Chinese standards, for example <a href="/facts/Addis_Ababa%E2%80%93Djibouti_Railway/plJeIflL">Addis Ababa-Djibouti Railway</a>.
