Insulation is not installed just for the process.
A lot of people think of it as part of the process to keep liquid warm or to keep it from freezing. But a lot of the insulation is actually for personnel protection.
OSHA is very clear on its rulings about personnel protection. Anything under 70” and over 160f is to be covered for personnel protection. That doesn’t mean the insulation blanket is laying on the deck creating a tripping hazard. When insulation is removed it needs to be reinstalled in a timely fashion (not months or years later) it has an important purpose for the process or for personnel safety.
The ruling is very clear:
We work in an environment where the piping is a lot hotter than 160f. In some areas that have frequent maintenance I have seen heat shields or wired mesh that stands out from the piping to protect the personnel.
Wherever we have to do routine work and we don’t have to hold the heat in, this wire mesh (above) makes more sense. It’s due diligence for operators that insulation be regarded and pursued as safety-related activity.
