Question

hoses of the oxy - fuel system should be protected from
select one.
a. dropping heavy items on them
b. all of these
c. sparks and flames
d. hot metal

Explanation:

Oxy - fuel hoses are crucial components in oxy - fuel systems. Dropping heavy items on hoses can cause physical damage such as cuts or punctures in the hose material. Sparks and flames can damage the hose through heat exposure, potentially melting or weakening the hose. Hot metal can also transfer heat to the hose, leading to degradation of the hose's integrity. Since all of these factors (physical impact from heavy items, heat from sparks/flames, and heat from hot metal) can damage oxy - fuel hoses, the answer is based on the comprehensive nature of the threats.

Answer:

B. All of these
