  • •Sandbags
  • •Elastomer mats
  • •Elastomer berms

Question 6

Oil Sorb

Answer 6

(diatomaceous earth)

• Uses: spread on edge, work back to source
• Limitations:
  
  • absorb weight in oil
  • Doesn’t float on water

Question 7

Polypropylene

Answer 7

• Uses: spread on edge, work back to source
• Limitations:
  
  • absorbs up to 25x its weight in oil
  • Will only absorb oil
  • Will float on water even if saturated with oil

Question 8

•Sandbags

Answer 8

• Uses: Place on flow path, butt ends together
• Limitations:
  
  • Good seal of leak difficult
  • Doesn’t absorb oil
  • Each bag is 70lbs/~32kg (very heavy to move)

Question 9

•Elastomer mats

Answer 9

• Uses: Place over storm/sanitary drains to seal them
• Limitations:
  
  • May not complete cover drains
  • Good seal difficult on rough surfaces or curbs

Question 10

•Elastomer berms

Answer 10

• Uses: Place in the path of flow to form barrier
• Lay around drain openings to form barrier
