8 lb. 3 oz. Coated Non-Salt Ice Melt

Yes, the shaker jug has a screw on lid and a very wide opening if you want to pour more in

No, you cannot use this on limestone steps.

modified carbonyidiamide crystal, special glycols, non-ionic surfactants accelerants, proprietary traction agents, special inhibitors. I don't know how much this will help you if at all, but these were the ingredients listed on the container. However I can attest that I have used this for several years on concrete pavers, and it has melted the snow and ice effectively without damaging the pavers which can be brutalized by other products.

Probably, but you should always check with your tile installer to make sure. Safe Paw is the only 'de-icer' that does not contain salt - and salt is usually what causes surface degradation problems. Two articles for you to read to help you - one is the ingredient list for Safe Paws; the other is a more general article on de-icers.

Yes, it should be safe on wood decks. From the Safe Paws information website - "...Children, pets, surfaces and the environment can be adversely affected by the use of rock salt and salt-based ice melter products used by households in the winter. A recent national survey shows that 60 percent of American households use these products in the winter. And, an alarming 62 percent are unaware of the health dangers associated with the use of these products. Safe Paw is the only 100 percent salt-free ice melter on the market and is 100 percent safe for children, pets, surfaces and the environment. It is the smart and safe product to use with winter, and Safe Paw's pellets are green to make it easy for consumers to know the difference. Rock salt and other salt-based ice melters contain sodium chloride or potassium chloride which can heat up to 175 degrees when exposed to water, ice and low temperatures. Often these white pellets (crystals) sit on ice and snow surfaces for a long period before penetrating into the ice. Exposure or digesting these salt compounds can cause health problems for pets and children. Moreover, the salt and salt residue left over from these products cause permanent damage to pavers, asphalt, concrete, wood decks, floors and rugs and can harm the environment, including burn and kill lawns and plants and contaminate well and drinking water supplies...." https://www.onlynaturalpet.com/products/Safe-Paw-Ice-Melter/202000.aspx
