Polymers

Polymers come with different

weights and percent of charge

!ll of this matters #ecause

different polymers will react

differently with your sludge

Polymer Safety

Dont get it in your

eyes1

2f you do, rinse withlots of water

2f you get it on s.in,

rinse with lots of water

Polymer Safety

Simply put, dont spill,

"ery slippery1

Dont use water1

2f spilled, use oil

a#sor#ent to co"er and

cones to mar. area1

Scoop up later and thenclean with water and

detergent until "ery clean1
