Legal requirements for including S2 S3 and S4 drugs, medications into first aid rooms and first aid kits?

under workcover and other nsw Acts, what must be done to gain approval to have drugs and medications e.g. asthma puffers, epi pens. included in workplace first aid rooms and first aid kits in the workplace and first aid kits outside of the workplace e.g. hiking

a risk assessment would have to be carried out, as would consultation with staff, a description of the likely hazards to be found in the workplace - dust - allergens.
what else?
I AM IN NSW AUSTRALIA, SO LOOKING UNDER NSW LAW
I would be most grateful for your responses

I doubt very much that you will be able to have medications such as S3 and S4 in first aid rooms and/or kits.

It's very hard to find somewhere that is even legally allowed to administer an S2 drug to anyone.

Because of the legalities concerning medications being given to persons with allergies to different meds, there isn't a great deal that any business/school etc can have in first aid kits and/or rooms.
