2.Installing safety devices

(1) Teeth contact preventive devices for circular saws
(2) Teeth contact preventive devices for wood working circular saws (for which the model examination is required)
(3) Anti-kickback devices for wood working circular saws, excluding those automatic feeding devices (for which the model examination is required)
(4) Guards for hand feed planer blades (for which structural standards are set)

5.Other safety measures

(1) Establishing signals for starting machine operations and designating those who give signals
(2) Wearing working caps and working cloths to avoid hair or cloth of workers being caught in power-driven machines 
(3) Prohibiting the use of gloves to prevent worker fingers from being caught by revolving blades during processing operations
(4) Requiring workers to  use personal protective equipment for avoiding cutting fragments flying from machines
