PROTECT YOURSELF FROM THE DANGERS OF YOUR OCCUPATION!
A person with occupational hazards (dangers) needs to be cautious in all respect.
For example, a Policeman 
needs to have strong positive frame of mind and impeccable value system as he may be dealing with criminals day in and day out. He needs to put an extra efforts to trust people, as by default his nature becomes suspicious.
A Doctor needs to keep his immune system stronger as he deals with patients all the time.
This applies to various occupations and therefore one needs to protect oneself depending upon the hazards one is exposed to.
May God bless us with the wisdom to remain alert & prepare well to protect our body, mind and intellect from the occupational hazards!
Tathastu! Swasti Siddham! Amen! So Be It!
