Final answer:
The statement is false because not all confined spaces are permit-required confined spaces. A permit-required confined space is defined by specific hazardous conditions that necessitate special safety procedures and permitting for entry.
Step-by-step explanation:
It is not safe to say that all confined spaces are also permit-required confined spaces. This statement is false. In occupational health and safety, a confined space is a place with limited entry and egress and not designed for continuous human occupancy. However, a permit-required confined space (also known as a permit space) has one or more of the following characteristics: contains or has the potential to contain a hazardous atmosphere, contains a material that has the potential for engulfing an entrant, has an internal configuration that could trap or asphyxiate an individual, or contains any other recognized serious safety or health hazards.
Permit spaces require controlled access and usually necessitate a permit system to ensure safety measures are taken before entry. Employers must evaluate whether a confined space is a permit-required confined space and take appropriate safety precautions accordingly.
