Please clarify. What industry? What material(s)? Size(s)? By "safe" are you talking about protecting workers from multi-ton loads, or avoiding damage to half-ounce pieces of medical tubing? Are these made of something known as carcinogenic that workers must avoid contacting, or are they something like sausage casings, that need to be kept sterile for safety?

CASING AND TUBING HANDLING RELATED TO DRILLING AN OIL OR GAS WELL.

IT HAS TO DO WITH THE ENERGY INDUSTRY (IE)OIL AND GAS INDUSTRY, DRILLING AND COMPLETION OF OIL WELLS

I worked at a place once when younger. Their handeling rules were, "THINK" and "Work slowly so you Don't get hurt and Don't harm the materials you handle". That was it.
