Moving tins of paint

Our boss had given us a task to move 2 tins of 15kg of paint from a storage room to our workshop and back again, we did not carry out a risk assessment as our boss had told us to call out the hazards there might be and he already knew we were all able to do it from the previous tasks. Our boss asked us what PPE we should be wearing and our answers were steel toe cap boots which protect feet from falling tins of paint, gloves so handle of paint doesn't rub on hands and goggles to protect eyes if lid isn't secure and if dropped could potentially splash up and hit eyes, after this talk i put on correct PPE and was ready for the task. We checked the access route the make sure there was no obstructions and went to get the paint. I carried one tin of paint weighing 15kg on each arm holding it by its handle which is the correct and safest way to hold it. We then carried it through to the workshop and stacked in a neat pile with 1 tin on top of another, once the boss was happy with the way we stacked them we carried them back to the storage cupboard and cleared up any mess we had made. After this i reported back to the boss to say i had finished
