1. The way to protect the energy transmitted to the human body from acute injury.

(1) When potential energy is converted into kinetic energy, the protection mode of absorption and buffering through the medium, such as safety hats, seat belts, etc.

(2) Electrical insulation protection, such as insulation Gloves.

(3) The use of reagents to turn acute harmful chemical energy into harmless protective methods, such as gas masks for acute harmful gases. Strong solvent protection with Nitrile Gloves.

(4) Protective methods for delivering fresh air to operators, such as various gas masks.

(5) Protection against flying objects and falling bodies, such as safety helmets, Protective Goggles, etc.

2. The way to protect the energy transmitted to the human body from chronic injury.

(1) Eliminate chemical energy protection, such as protective clothing to protect the whole body.

(2) Absorb and reduce noise energy, such as earplugs.

(3) Shielding of radiant heat energy, such as high temperature protective clothing.

(4) Radiation shielding, such as anti-ultraviolet shielding mirror.

3. Classification by physiological parts of the human body
