Chlorine storage near iron pipes

We have an outside accessible storage room/closet that I store my pool chemicals in. It says cool and dry. I do have a bathroom style fart fan in there, that I do run from time to time. The room was added on to an existing structure, as as such, what used to be outside natural gas lines that went from the dirt into the building are now inside the room in the corner. I've been storing my chlorine tabs in the stock Leslie's bucket over there.

These pipes were a little rusty to start off with, but I have noticed over the past few months (the room is only about 6 months old), the iron pipes have rusted a considerably more.

First off....Yes I am going to paint primer on them. I acknowledge I should have done that on day one, but failed to do so. Yes, I also acknowledge that chlorine fumes are corrosive. The fumes are not bad in the room, so I never would have imagined this, but also know that exposed iron pipes are very easily rusted.

1) I will paint some primer on these pipes to seal them up.......was planning on just some liquid rustoleum primer brushed on nice and thick.
2) I have my fart fan on a timer now. I now have it scheduled to run for 4 hours, then off for 4 hours, and repeat this 24/7.

Where my question comes in play.......should I be concerned or do anything else to prevent permanent long term damage? Would moving the chlorine to a different corner be helpful? Photo below is of the corner of the storage room.

It is the acid in the chlorine tabs that is most likely causing the corrosion. Any acid should be stored OUTSIDE in a deck box or similar. I store liquid chlorine in my garage and have no issue with corrosion. I store MA outside in a big rubbermaid storage unit.

Store the pucks outside as well in a storage unit but separate from the MA liquid as they need to be separated.

Read the above 👆 before it's too late based on where you're shopping, and the chemicals you're adding to your pool.
All of those products are poorly suited for pool care in our area. You'll be in a world of hurt before you know it.

Ok. Thanks. I’ll get some outdoor storage “lockers” to store the MA and chlorine in.

I see you are in Katy. Do you have any issues with texas temps degrading the quality of the chemicals over time (as long as stored out of direct uv light???

Pucks and MA are long lasting. It is just liquid chlorine that I store in my garage in a cabinet. It does degrade mainly because I use it sparingly as I have a SWCG.

I've seen chlorine eat so many bicycles, lawnmowers, plumbing, and everything else that might be stored in a garage or shed, that I just store my chemicals in a separate weather-proof chest. We just had a severe storm blow thru, sideways rain drops the size of marbles, and everything inside is still dry. Most importantly, other than some screws and hinge hardware, the whole chest is plastic... nothing to corrode.

I chose a spot close to my equipment, and between skimmer and one of the returns, so I could easily grab and dump whatever chemicals are needed, start/stop pump, etc. Beats walking back and forth to the garage or shed, everytime I need a chemical. I poured a small concrete pad to set it on, since our ground is sloped, and to keep it up off the dirt where it's dry. If it lasts a few years, great... cheap to replace.
