Safety in pressure systems - Personal Protective Equipment list gets extended

Hazards are more in pressure systems with the possibility of explosion/bursting. Pneumatic pressure is more harmful compared to hydraulic pressure. But, both are dangerous. 

It is the common and minimum standard for any worker to wear personal protective equipment (PPE) like, safety shoes and a helmet while working, but, I heard that the use of a face shield also is a new addition made to protect the person from flying particles/objects/splash, etc

Now, as mentioned above, pressure systems can cause bursting/flying particles/splash, etc, and compulsory use of face shields will help the workplace personnel from exposure to hazards.
