Bob Bartholomew July 1992
DO A 04697ft C0NFTDFNTTA1
C-9 SCOTT AIR PACK TESTING--MARCH 1992
A. SPECIFIC ITEMS COVERED WITH EACH INDIVIDUAL WERE: 1. OPERATION OF THE REGULATOR BYPASS VALVE, MAIN LINE VALVE, AND PRESSURE DEMAND SWITCH--WHEN, WHY, AND HOW TO USE THEM. 2. EXPLANATION OF THE DEMAND FEATURE. 3. EXPLANATION OF THE WARNING ALARM AND ACTIONS TO TAKE. ' 4. PROPER METHOD OF DONNING AND DOFFING THE AIR PAC AND FACE MASK.
B. EACH EMPLOYEE PRACTICED DONNING AN AIR PACK.
NOTE: SINCE MOST TECHNICAL AND DAY OPERATIONS PERSONNEL ARE NOT REQUIRED TO BE ABLE TO USE A SCOTT AIR PACK IN THEIR NORMAL WORK DUTIES, THEY WERE NOT TESTED FOR DONNING SPEED. INSTRUCTOR: DONNIE LANDRY
