Before the F370, all dissolvable support material was a translucent black. This meant that the bath would become a milky brown when it needed to be changed. Now the F370 introduces an opaque white material which causes the bath solution to continuously appear milky which creates confusion when trying to figure out when to change the solution. − ***As of right now, we recommend making a best guess. When the bath starts taking a very long time to dissolve support material, it is probably time to change the bath. − ***Some thoughts for changing this in the future: − ****Use the Job Log's ability to track the support material dissolved in the bath and develop a number for when the bath needs to be changed. Then set the Job Log up to alert the Lab when it has reached that number. − ****Attempt to obtain translucent black support material for the F370. − ****Attempt to use a chemical strength measurement to determine how strong the solution in the bath is and determine a checkpoint strength for when to switch the solution.

*Follow the MSDS procedure in the event of getting Sodium Hydroxide on your skin, in your eyes, or if you ingest it.
*The MSDS is located next to the sink in a bright yellow binder hanging on the wall. It includes the fluids the Prototype Lab uses that could be dangerous when humans are exposed to it, and it details what to do if the fluid is ingested, gets in your eyes or on your skin, and other pertinent information.

*'''What to do if the bath is beeping:'''
**This typically means the bath is low on water (below 1.5 horizontal holes of the basket inside).
**Take the clear bucket under the sink and use it to fill the bath until the fluid level inside is only 1.5 horizontal basket holes from the top.
**Tell the Bath Ace if you think the solution should be switched, do not do it yourself.
**The bath may be sending out an error message in which case the Instruction Manual should be consulted.
*'''What to do if the bath appears to be leaking:'''
**Immediately inform the Aces of the Lab and/or Justin.
**This would mean there is a collection of water inside of the grey catch tray underneath the bath.
*'''What to do in the event of a spill:'''
**Evacuate the lab and shut it down until the spill has been properly cleaned.
**Immediately inform the Aces of the Lab; if unavailable and the spill is large then contact Security.
**Use the spill kit.
***There should be instructions inside.
***Make sure you are wearing safety attire.

# '''How to change the solution in the bath:'''
#* Wear safety attire during the entire process.
#*Retrieve a barrel to drain the fluid into.
#*Unscrew the top of drain spout (make sure the drain spout is completely pushed in before unscrewing).
#*Swivel the drain spout to face down.
#*Align the barrel opening to be underneath the drain spout.
#*Pull the drain spout out so that the fluid begins to drain.
#*Completely drain all of the fluid.
#*''Clean the inside of the tank'':
#**Use water to rinse out the inside of the tank then use paper towels to wipe out the gunk.
#**Be sure to also clean the basket thoroughly.
#**Replace the basket.
#*Fill the bath up with water (use the clear bucket under the sink, fill this with water from the sink, pour the water into the bath) until the water level reaches 1.5 horizontal basket holes from the top.
#*Turn the bath on and have it heat up to 70 degrees Celsius.
#*Take a pre-filled bottle of Sodium Hydroxide (located in the thin cabinet underneath the counter the bath sits on) and sprinkle some into the heated water.
#*Allow the sprinkled amount to dissolve and repeat until all of the Sodium Hydroxide in the bottle has been dissolved in the bath.
#*Refill the Sodium Hydroxide bottle if there is only one filled bottle left.
# '''How to fill new Sodium Hydroxide bottles:'''
#* Wear a lab coat, nitrile gloves, and safety goggles. This is very important. The granule Sodium Hydroxide (undiluted--undissolved) is much more dangerous.
#*There should be a mini funnel in the lab somewhere (it tends to move around some). Use the large Sodium Hydroxide bottle and mini funnel to refill the small bottles up to where the level in the last remaining bottle is. Always leave one bottle filled as a gauge for where to refill to. If a bottle has not been left filled, then fill the small bottle to about 1.5 inches below where the narrowing of the bottle begins.
