Sign in Hindi in an abandoned tunnel of the Loharinag-Pala Hydro Power Project (India)
I think the text on the sign means:
Safety Pledge:
I pledge that I will take possible steps for myself, my family, community, and country to prevent accidents, work-related hazards, and to protect the environment.
H.S.E
H.S.E. stands for Health, Safety, and Environment.
