*4.1.1 Specialty-specific HSE guidance (HSE guidance)*

HSE guidance is a guiding document which is used to reduce the HSE risks arising from discipline-related conventional operations to the ALARP level through risk management. Through the risk management process, countermeasures against the HSE risks to be managed are developed. Then these countermeasures that are distributed to relevant positions with written records are kept. After being reviewed by the competent department (personnel), the written records are compiled into the HSE guiding document specific to the discipline.

As the HSE risks arising from discipline-related conventional operations are relatively stable, there would be no change in the corresponding prevention and control measures as long as no change occurred to process, technology, equipment, facilities, etc. If there are risks that resulted from temporary changes, control of such risks should be carried out by means of the HSE plan. Certainly, if there are risks that resulted from forever changes, the HSE guidance should be modified. Therefore, the HSE guidance is relatively stable.
