Maybe it wouldn't have been suitable for your DS. As far as Heath and safety goes though, here are some of the checks we have had.
My health, and immunity to various infections are checked every few years. (Some of my charges bite!) I have a full medical, and assessment.
The ventilation
The temperature of heating and hot water.
The temperament and health of our animals (vet's report)
All the usual gas service certificates.
The security of the external doors. Also the security of the garden gate and fences.
The nature of plants in the garden
The cleanliness of the house and garden.
Electrical tests.
Safety features such as cupboard locks and stair gates. The storage of medication belonging to charges, or to family. Whre anything such as knives or alcohol is kept.
the night time clothing of the whole family is inspected, we all need dressing gowns and slippers to come out of the bedroom.
The fire alarms, smoke alarms, CO alarms, fire extinguishers, fire blankets, first aid kits, and fire escapes are inspected.
The nutritional content of the fridge and storage cupboards.
The record keeping
I've even had inspectors check under my bed. I asked what h was looking for, and was told that he had heard of one carer somewhere in the country who had a pet snake which wasn't on their vet's certificate, and they hid it under the bed.
The non choking size of any objects within reach.
I really cannot remember what else, to be honest, but if you think of one I have not said, tell me, and I will say if we do that check or not.
