Aluminum sulfate is also odorless, but when heated it may release toxic gas. To ensure proper product stewardship, you want to be sure your aluminate sulfate distributor is transporting it to you safely and responsibly. If you are buying aluminum sulfate in bulk, you need to avoid damp areas, or anywhere where rainwater could reach it.
