My father works with chemicals ST-22, BT-DA, BT-A, BT-SX, and CST-300 to treat the water in a large boiler system. They are in properly labeled containers. However, they are in the room where the employees are during the entire lengh of their shift. He feels there might be an OSHA law about their storage but I can’t find it. Does anyone know, or can they provide me with a great link? Thanks!

My water cooler also has a hot and cold dispenser, does it make a difference if I keep the machine turned on or should I turn it off? It has been in storage for a few months, and I want to make sure it is very clean before I use it again.

The hot water is not hot when I press the hot button. I can get cold water when I press the hot button. There is a small storage under the water cooler so I do want to fix it. I’d like to try to fix it by myself. We use the hot water a lot more than the cold water. so I do need this function work properly. Please tell me how to fix it or what parts do I need to buy and try. Thanks.
