    Pre-Operational Inspection 

Before each entry into a contaminated area, the following inspection must be 
performed to ensure proper function of the respirator system. If damage is 
found on any component, do not use.

1. PAPR System 

  •  Closely inspect the entire EVA Powered Air-Purifying Respirator (PAPR) 

system including the filter / cartridge, battery, hood and breathing 
tube. Pay attention to component connection points for wear and 
damage. If parts are missing or damaged, replace them with only 
Bullard branded/manufactured replacement parts before proceeding. 

2. Filter / Cartridge 

  •  Inspect the filter / cartridge for physical damage.  
  •  Check the label to ensure the filter / cartridge has not exceeded its 

“use-by” date. 

  • Inspect the gasket on the filter for physical damage. 
  •  Ensure that the correct filter / cartridge is appropriate for the 

contaminated area. 

3. Battery 

  •  Inspect the battery for any physical damage.  
  •  Check the Fuel Gauge to determine sufficient charge is available. 
  •  The battery must be latched to the turbo-blower. The battery tab will 

click when completely engaged. 

4. Hood 

  •  Inspect the hood for any physical damage.  

5. Breathing Tube 

  •  Ensure that a rubber gasket is installed into the air source connection 

on the turbo-blower unit. 

  •  Examine the breathing tube for tears, holes, or cracks.  
  •  The breathing tube should screw securely into the air source 

connection and the hood. 

6. Airflow Check 

  •  The EVA Powered Air-Purifying Respirator (PAPR) system is pre-

calibrated to ensure required airflow. However, the Airflow Indicator 
must be used to verify minimum required airflow is attained prior to 
each day’s use. The airflow should be checked with your current filter / 
cartridge installed.  

  •  See Checking Airflow with Airflow Indicator under Operational 

Instructions for correct operation of the airflow check. 

7. Check Low Flow Alarm 

  •  See Checking Low Flow Alarm under Operational Instructions to verify 

Low Flow Alarm is functioning properly.
