FROM M. E. WAGNER UNIT SUPERVISOR - PAINT & INSUIATION TO MR. J. K. MCCIAIN SAFETY RULES COMMITTEE 1977 November 07 &U&- / RE: EXCEPTION TO SAFETY RULE S3 ON PAGE 29 The Insulation Department uses a Ceramospray machine that blows insulation on tanks, vessels, large pipe, etc. A large hose is the carrier for the fibrous-type material. The size of the hose is approximately 2-1/2 X 50'. This machine is used almost constantly as it is a major improvement, par ticularly when insulating vessels and tanks, over previous methods. The problem is that the carrier hose frequently becomes choked up due to mois ture (or even humidity can be a factor) in the material being sprayed. According to Rule #3, Page 29 ("Compressed air must not be used to clear blocked or choked lines."), we cannot use plant air to clear our hoses. To unchoke our hose by taking it apart takes from one hour to eight hours as opposed to approximately ten minutes by clearing the hose using plant air. I propose an exception to Rule #3, Page 29. By removing the hose from the blowers on the machine, laying the hose on the ground, securing each end to prevent undue or unsafe movement of the hose, and using plant air (90 lbs p.s.i.) to clear the hose; we could be able to.continue work without vast amounts of downtime. The hose would be laid on the ground, barricaded, aimed in a direction where it could injure no one nor any thing. The persons using the air hose would be wearing a face shield in the event of a "blow-back". Should a ,rblow-back" occur, it would be equivalent to being hit with large cotton balls. To securely anchor the hose, we would lay the hose next to steel columns and tie them firmly. I respectively request an exception to Rule #3, Page 29 of the "Safety Rules" book, Point Comfort Operations. M. E. WAGNER MEW/cmp PLAINTIFFS ! EXHIBIT AL-153 ALCOAOOOH25
