Are there any upper limits imposed on warehouses storing corrosive materials such as Glacial Acetic acid or Sodium Hydroxide.

limited by the floor surface area and height of compartment. Glacial Acetic is also flammable.

Apart from looking at the overall suitability, if you are storing very large amounts you may want to check with COMAH regs schedule 1 table 3 for 'Categories of Substances and Preparations not specifically named in Part 2 .'

You also need to make sure your warehouse is big enough in order to be able to segregate chemicals that can react with one another. You name an acid and an alkali. They need to be kept apart.

All the above is good advice, a good publication that may help is Chemical Warehousing The storage of packed dangerous substances HSG 71

Just a point of Clarification.
COMAH only relates to substances that have a 'toxic', 'fire' or 'environmental' hazard. It does not apply to substances that only have a corrosive hazard. Therefore you can store as much Caustic as you like within falling into COMAH. The Glacial Acetic Acid however will have an impact.
But - COMAH does not limit quantities, it only imposes more duties on the the company if you exceed certain amounts.

Typically, this is limited by the floor surface area and and height of each fire compartment.
For medium risk the floor surface area is 4000 m-2. For high risk storage, In the UK & Wales the volume of materials must be less than 20,000 m-3, i.e. floor surface area is upto 2000 m-2 and 10 m height or 4000 m-2 and 5 m high. In Scotland & ROI high hazard is limited to 1000 m-2.
The EU Comite European des assurances (CEA) suggest a limit upto 7200 m-2.
