Fully read the instructions for set-up and operation of all heating devices to be used in the lab experiment. Provide instructions for operating devices at each lab station to reinforce information that is presented in lab demonstration.
Thoroughly clean the work space to remove residue of any chemicals used in prior experiments. Use a lab-safe cleaning product that specifies on the container that it is not flammable.
Prepare a steam-heated device for experiments that require heating of less than 100 degrees Celsius, as steam-heated devices do not have risk of shock or spark like hot plates, heating mantles and tapes, furnaces, ovens and baths do. Fill the device with a sufficient supply of water to conduct the entire experiment.
Secure the actual heating elements of devices, tucking them out of the way when possible, to protect workers from accidentally touching parts that are electrically charged. Place heating devices in areas that are out of reach of sinks, water or flammable chemicals that could splash the device.
Prepare only heating devices that are in good working condition. Discard damaged or broken heating devices, rather than setting them to the side where they might be used inadvertently. Also remove from lab space any chemicals or devices not involved in the experiment.
Place insulating pads on the table or work space so that no hot apparatus is ever placed directly onto the table. Place safety goggles, lab coats, gloves and other protective gear next to each station. Provide enough gear for every person in the laboratory, including those people only observing experiments.
Place a fire extinguisher, chemical burn powder and other safety products, depending on the nature of experiment, in the lab in case there is an emergency.
