OSHA has no authority over the Public, only over the workplace. A public walking surface is unlikely to be subject to OSHA regulation.
A device that is always used as a reference surface is called a benchmark or a standard. These devices provide a known point or dimension to compare other measurements or objects against.
Maximum recess dimension allowable from the front edge of a box or plaster ring to the surface face of the drywall?
global winds, Coriolis effect, and continental deflection
The platinum electrode is commonly chosen as a reference electrode for measuring standard cell potential. This is because platinum is inert, has excellent conductivity, and does not participate in redox reactions, making it a stable reference point. In electrochemistry, the standard hydrogen electrode (SHE), which uses a platinum surface, is often used as the universal reference electrode.
Surface currents in the Southern Hemisphere are deflected due to the Coriolis effect, which is caused by the rotation of the Earth. In the Southern Hemisphere, this deflection causes currents to flow clockwise around high-pressure systems and counterclockwise around low-pressure systems. This deflection influences the direction and path of surface currents in the ocean.
The three factors which control surface currents are the following:Global windsContinental deflection and temperatureThe Coriolis effect

Reflection: When light is bounced back off a surface in different or same direction Deflection: When light goes through a surface but its direction has changed from before it hit the surface

A reference line is a line that is perpendicular to the surface at the point of incidence. It is used as a point of reference for measuring the angles of incidence and reflection relative to the surface. The angle of incidence is measured between the incident ray and the reference line, while the angle of reflection is measured between the reflected ray and the reference line.
Charged particles along the Van Allen belts are deflected by the Earth's magnetic field. This deflection prevents the particles from reaching the Earth's surface, protecting us from harmful radiation.
