Distress hand signal

A distress hand signal is a hand signal to indicate distress and need of rescue. There are many different types of Distress hand signals down below.

Maritime and aviation

Hands raised in a Y shape to signal distress to a rescue helicopter

For shipwreck incidents, various slight gestures with arms can indicate the needs of an individual, from being noticed to being rescued. At sea, the oldest hand signal to indicate distress is to flap the arms up and down. Cloth or bright objects may be held to increase visibility.^[1]

In aviation, a downed pilot would hold their hands straight above their head to indicate that they want to be picked up. If they need help repairing their aircraft, they would hold their arms out straight to the side.^[2] One method of signalling an emergency to a rescue helicopter is to raise one's arms in a "Y" shape, indicating that "yes", rescue is needed. (Conversely, one arm raised and one lowered signifies an "N" for "no".)^[3]

Women's Signal for Help

The Signal for Help designed and publicised by the Canadian Women's Foundation

During the COVID-19 pandemic, there were extensive lockdowns which kept people at home. As people then mainly communicated by social media, in 2020, the Canadian Women's Foundation (CWF) devised a hand signal called the Signal for Help which women could use to secretly indicate that they were at risk of domestic violence or victims of human trafficking and so needed assistance.

The CWF signal has the palm outward with the thumb across it.^[4] The fingers are then closed over the thumb to symbolize that one is being held or hurt.

Knowledge of this signal spread through social media such as TikTok. In 2021, a girl in Kentucky used the signal when she had been kidnapped, and people who saw it alerted the local police who rescued her.^[5][6] As a result, the Women's Signal for Help is an option that allows those who feel abused to discreetly ask for help without alerting the abuser or leaving a digital record of their request. ^[7]

Mayday hand signal

'STOP' Mayday hand signal used by ramp crew

First used in 1923, the mayday hand signal is an important nonverbal communication method in the area of aviation, as the ground handlers of a ramp crew, when visual contact is impaired or they cannot contact the aircraft, can use it to convey a life-threatening emergency.^[8][9]

This signal is "X" shape, which involve two arms crossed and raised above the head, and this signifies to pilots or other coworkers or people around them that there might be a fire, fuel spill, aircraft malfunction. This signal greatly ensures timely awareness of the situation, immediate emergency solutions, evacuation, or firefighting; this leads to avoidance of accidents and maintenance of safety and security of the aircraft and people.^[10]

Raised fist

Popular within social justice movements, the raised fit is a symbol of solidarity and resistance to oppression, such as issues related to gender equality and human rights, resulting in the manifestation of empowerment and unity.

It has been adopted in Western feminist movement, fight for civil rights, and labor activism to speak against oppression.^[11] It was first popularized in the workers struggle in the early 20th century but became a recognized symbol of protest during Black Power Movement of the 1960s and continues to be used as a form of protest today.^[12] The gesture has an effect of shared power and resistance against social and political injustice.
