  1. 1. Donald F Groce Showa Best Glove Inc
  2. 2. Is this the right glove?Needs Dexterity Not Much Exposure Can’t Really Wear a Thick Glove Is a Thin Glove Enough Protection? Would a Thicker Glove be Clumsy and Unwieldy?
  3. 3. Needs Maximum Protection Heavy Exposure May be Unknowns Present Exposure Could be Life Threatening Make Sure the Choice is Clear
  4. 4. There are Hundreds of Chemicals How to Choose Gloves What Polymer is Safest How Long Will I be Wearing the glove? How Much Exposure? How to find the Answer On- Line?
  5. 5. Sometimes the Hazards are Not Life Threatening What Glove Should I use for Limited Exposure? What glove Should I use for dilutions of chemicals?

  31. 31. Results: Nitri-Solve® 727 and 730 Viton 890 and 892 ANSI Level 6 >480 Minutes is Displayed
  32. 32. These Gloves Do Not Work Not a Good Choice Gloves Become Swollen and Tear Readily Degradation shows severe changes in minutes
  33. 33. Intermittent Exposure Data Even for Limited Exposure, the Choices are Very Limited. ANSI Level 1 N-DEX Not Recommended Select the same gloves as Heavy Exposure.

  35. 35. Problem: A customer is using a solvent to remove sticky glue. MSDS Shows the main ingredient is Hexane Go to www.chemrest.com Select a glove for use with Hexane
  36. 36. Problem: Using previous results found, the customer has requested documentation. Please save the information from www.chemrest.com as a PDF Go through steps to email to customer
  37. 37. Problem: Same Customer Their exposure is limited or intermittent. Show the Intermittent Data to show what other gloves may work for Limited Contact in www.chemrest.com
  38. 38. Problem: Same Customer The Customer wants documentation of the Intermittent Data. Make a PDF of the data and send to the customer using email using www.chemrest.com
  39. 39. Problem: Same Customer The Customer wants a product sheet for Nitri Solve 730 gloves Find the Product Sheet PDF and send to the customer using email using www.chemrest.com
  40. 40. Problem: Same Problem Customer wants three things: a product sheet for Nitri Solve 730 gloves They also want documentation of the Heavy Exposure Data. They also want documentation of Intermittent Data. Make one PDF of all of the desired data and send to the customer using email using www.chemrest.com
