Do not store Plastisol or Liquid Plastic near rain, water, outside or any areas that may moisture that may contaminate M-F Plastics.

Once plastic has been heated properly than you may use Plastic for multiple uses.

Equipment: 
As far as equipment goes, a lot depends on how you melt your plastisol (microwave, hot plate, pot, light bulb set up, etc) 
but many things are common. You need eye protection for potential splashes. Any safety goggles will do. 
Be sure to wear goggles over your regular glasses or contacts!!! Goggles have a better coverage area. Always wear 
long pants and either a long shirt or something to cover your arms. Hot plastic is ROUGH on skin.
Shoes or boots should be closed (no flip flops!!) to protect against a spill or falling object! You may even 
want to wear a heat resistant apron to further protect your clothing. Heat resistant gloves are also something to have on hand. 
Whether you are handling a hot injector, hot molds or hot cups of plastic, gloves protect your skin and fingers nicely. 
Get a nice floor mat if you stand a lot. It can ease your pain in your legs, knee’s etc and is well worth the money.
Don’t pour in your kitchen or heat your plastic in your kitchen microwave.
Kids and pets don't mix with 350 plastic either. Clear your workspace prior to starting any 
work.

Work Area:
Make sure you have adequate area to work and that you have a comfortable counter top for your height. 
Keep your cups, pots, and other heating/stirring devices clean and dry. 
Water and hot plastisol DO NOT MIX! You will get bubbling, spurting, etc if you get water in your plastisol or visa versa. 
That also goes for water based scents. 

Ventilation and Masks:
This is a real important area that some may choose to skip because of cost but will regret in the long run. 
Asthma induced from plastisol fumes will end your pouring fun in a minute. Your area needs good ventilation! 
Some use kitchen exhaust hoods, some just pour in the garage with the door open. 
Regardless of where you are, get the fumes out so they don’t build up in your work area! 
Some recommend masks to further filter out particles.

Injecting Molds:
Wear both gloves.
Keep a bucket of water nearby (on the floor).
If you do get plastic on your skin - don't try and wipe it off - it only smears and makes it worse.
Clamp your molds well - when in doubt use multiple clamps.
Hinges are for the convenience of keeping the mold halves together and should not be relied on for safety.
Don't ever force the injector - our injectors are very smooth
if it's not pushing plastic with less effort than the weight of your hand something is wrong. 
Forcing it will not result in good things - stop and find out what's wrong.

Cold weather:
Don't set a hot cup on a cold surface, it can explode.
A lot of people have reported having problems with cups other than the Pyrex brand.
Always inspect your equipment and make sure it is in good working order.
Don't cool your baits with the sprue / run in water and then try and remelt them. 
They have water in them and as already mentioned - water and plastic do not mix. 
Remove the sprue / runner before putting in water if you want to remelt them.
