Is it necessary to wear full-body protective clothing when unloading 32% liquid caustic? It's so hot.

As the title says. Please ask the experts for advice.
Our factory has never emphasized this, nor have we heard of anyone doing it; we also use alkali, but unloading is not our responsibility. I’ve seen hydrochloric acid being unloaded; it happens right next to our workshop, so it’s not uncommon. This substance is much more aggressive than alkaline solutions, and I’ve never seen anyone wear protective gear when working with it. But there must be a prerequisite for this: in addition to protective gear, it is necessary to know how to do things properly to ensure reliability.
When handling concentrated sulfuric acid, a chemical protective suit is necessary; for 32% alkali, a face shield, rubber gloves, and safety shoes should be sufficient. The specific requirements depend on the level of risk associated with the operation
Acid and alkali resistant clothing, acid and alkali resistant gloves, splash-proof mask – heat is no excuse; procedures must be followed
Protection is necessary. It is even more important to take precautions in hot weather, as the skin absorbs substances more easily.
I don’t need any of that; for neutralizing alkalis, I just use a protective mask and rubber gloves, and I follow the operating procedures strictly. There’s an emergency first-aid kit nearby, containing around 3% boric acid as well as eye wash stations and spraying facilities. It is stated in the MSDS: wear acid- and alkali-resistant protective clothing and a positive-pressure respirator during emergency handling
Wear protective clothing, but it doesn’t need to be heavy-duty; after all, they are all chemicals with some corrosive properties
Thank you all for your replies, thank you!
We bought those lightweight, disposable, full-body protective suits. They all said it was too hot; sometimes they were on the verge of heatstroke. Our operation simply involves unloading the cargo – connecting a hose from the vehicle to our receiving tank. It mainly involves turning the valves on the vehicle on and off.
