Evaluations

Evaluation of a Self-Contained Breathing Apparatus 

Involved in a Near Miss in the Fire Service

Birmingham Alabama Fire Department Request 

for a Scott® Safety Air-Pak® Model 4.5 unit

As part of the National Institute for Occupational Safety and 

Health (NIOSH) the National Personal Protective Technology 

Laboratory (NPPTL) agreed to examine and evaluate a Scott® 

Safety Air-Pak® model 4.5, 4500 psi, 30 minute, self-contained 

breathing apparatus. 

This SCBA status investigation was assigned NIOSH Task 

Number 21002. The Birmingham Fire Department was advised 

that NIOSH NPPTL would provide a written report of the 

investigation and any applicable test results.

The SCBA was delivered to the NIOSH facility in Morgantown, 

WV on August 8, 2016 and transported to lab H1513 for 

secured storage. The unit was removed from secured storage 

for inspection on August 29, 2016 and placed back into secure storage until the 

performance testing was conducted on December 8, 9, 13, and 14, 2016. All movements 

of the SCBA unit are tracked on an entry log each time it is removed from the secured 

storage area for inspection and performance testing, and returned. 

NIOSH evaluated an SCBA 

used by a fire fighter 

involved in a near miss 

incident. The SCBA was not 

found to contribute to the 

near miss. 

A qualified service 

technician must inspect, 

repair, test, clean, and 

replace damaged 

components of any SCBA 

involved in an incident 

before it may be returned to 

service.

 Disclaimer

The purpose of Respirator Status Investigations is to determine the conformance

of each respirator to the NIOSH approval requirements found in Title 42, Code

of Federal Regulations, Part 84. A number of performance tests are selected

from the complete list of Part 84 requirements and each respirator is tested in

its “as received” condition to determine its conformance to those

performance requirements. Each respirator is also inspected to determine its

conformance to the quality assurance documentation on file at NIOSH.

In order to gain additional information about its overall performance, each

respirator may also be subjected to other recognized test parameters, such

as National Fire Protection Association (NFPA) consensus standards. While the

test results give an indication of the respirator’s conformance to the NFPA

approval requirements, NIOSH does not actively correlate the test results from

its NFPA test equipment with those of certification organizations which list

NFPA-compliant products. Thus, the NFPA test results are provided for

information purposes only.

Selected tests are conducted only after it has been determined that each

respirator is in a condition that is safe to be pressurized, handled, and tested.

Respirators whose condition has deteriorated to the point where the health

and safety of NIOSH personnel and/or property is at risk will not be tested.

Investigator Information

The SCBA performance tests and inspection were conducted by Angie Andrews, Jeremy Gouzd,

and Karis Kline of the Morgantown Testing Team, Evaluation and Testing Branch, National

Personal Protective Technology Laboratory, National Institute for Occupational Safety and

Health, Morgantown, West Virginia. The report was also written by this team.

SCBA Inspection

The unit was removed from the packaging in Lab H1513 and inspected on August 29, 2016 by

Angie Andrews, Jeremy Gouzd, and Karis Kline of the Morgantown Testing Team at NPPTL.

The unit was identified as a Scott® Safety Air-Pak®model 4.5, 30 minute, 4500 psi unit, with 

NIOSH Approval Number TC-13F-76CBRN, and as the unit submitted by the Birmingham Fire 

Department. The SCBA unit was visually examined, component by component, in the condition

received to determine the conformance of the unit to the NIOSH-approved configuration. The 

visual inspection process was documented with photographs. Once the inspection was 

complete, the SCBA unit was repackaged and placed back in the secured storage area. 

The complete SCBA inspection is summarized in Appendix I. Photos of the SCBA components 

are included in Appendix III.

SCBA Testing

The purpose of the testing was to determine the conformance of the SCBA to the approval 

performance requirements of Title 42, Code of Federal Regulations, Part 84 (42 CFR 84). Further 

testing was conducted to provide an indication of the conformance to the National Fire 

Protection Association (NFPA) Airflow Performance requirements of NFPA 1981, Standard on 

Open-Circuit Self-Contained Breathing Apparatus for the Fire Service, 1997 Edition.

NIOSH SCBA Certification Tests (in accordance with the performance requirements of 

42 CFR 84):

Summary and Conclusions

An SCBA unit was submitted to NIOSH NPPTL by the Birmingham Fire Department for 

evaluation by telephoning to request the evaluation. The SCBA unit was delivered to NIOSH 

on August 8, 2016 and extensively inspected on August 29, 2016. The unit was identified as a

Scott® Safety Air-Pak® model 4.5, 30 minute, 4500 psi unit with NIOSH Approval Number TC13F-76CBRN. As a result of the inspection, it was determined that the unit was in good 

condition. An empty cylinder was delivered with the unit, with the valve in the off position.

The regulator and facepiece sealing areas were relatively clean and in good condition. The 

facepiece had only slight scratches on the lens. Visibility through the facepiece lens was good. 

The facepiece head harness and the straps were in good condition and the straps moved

freely, but were slightly dirty. The NFPA approval label was present and legible. The personal

alert safety system (PASS) functioned.

The facepiece provided by Birmingham Fire Department broke at the lower left attachment 

point during donning onto the headform. It was replaced with a NIOSH-owned Scott® facepiece 

for the remainder of the tests.

The SCBA submitted by the Birmingham Fire Department did not meet the requirements of all 

six NIOSH SCBA certification tests. The unit failed the NIOSH Positive Pressure test (Standard Test 

Procedure Number 120, 42 CFR Part 84 Reference: Subpart H, 84.70 (a)(2)(ii)). The unit passed 

the NFPA “Airflow Performance” test. 

A Certified Product Investigation Process (CPIP) was initiated due to the unit failing the NIOSH 

SCBA Certification Positive Pressure Test. The purpose of the CPIP Program is to ensure that 

NIOSH-approved respirators continue to meet or exceed the criteria on which the approval 

was based. The SCBA unit was returned to secured storage pending shipment.

If the unit is to be placed back in service, the SCBA must be repaired, tested, cleaned and any

damaged components replaced and inspected by a qualified service technician, including testing

and other maintenance activities as prescribed by the schedule from the SCBA manufacturer.

Typically a flow test is required on an annual basis, at a minimum.

I. Background

On August 8, 2016, an SCBA unit from the Birmingham Fire Department was delivered to the

NIOSH facility in Morgantown, West Virginia. The unit was removed from the packaging in Lab

H1513 and inspected on August 29, 2016 by Angie Andrews, Jeremy Gouzd, and Karis Kline of 

the NPPTL Morgantown Testing Team (MTT). The SCBA was visually examined, component by 

component, in the condition received to determine the conformance of the unit to the NIOSHapproved configuration. The unit was identified as the Scott® Safety Air-Pak® model 4.5, 30 

minute, 4500 psi unit, with NIOSH Approval Number TC-13F-76CBRN, and as the unit 

submitted by the Birmingham Fire Department. The visual inspection process was 

documented photographically. The unit was tested December 8, 9, 13, and 14, 2016.

II. Test Outlines

1. POSITIVE PRESSURE TEST – NIOSH Standard Test Procedure Number 120, 42 CFR Part 84

 Reference: Subpart H, § 84.70 (a)(2)(ii)

Requirement:

The pressure inside the facepiece in relation to the immediate environment is positive

during both inhalation and exhalation.

Procedure:

A breathing machine with a 622 kg-m/min cam operating at 24 RPM with a 40 liter per

minute flow rate (115 liters per minute peak flow) was connected to an anthropometric head

for cycling. A pressure tap in the head was connected to a transducer which in turn connects

to a strip chart recorder for determining the pressure in the facepiece.
 

TN-21002 Birmingham, Alabama Fire Department – Status Investigation Report 11

 

Results: The unit was tested on December 8, 2016 and did not meet the test requirement.

The inhalation breathing resistance did become negative during the test. The HUD, remote

gauge, and donning switch functioned normally.

Inhalation Breathing Resistance:

Pass/Fail: Fail

2. RATED SERVICE TIME TEST – NIOSH Standard Test Procedure Number 121,

42 CFR Part 84 Reference: Subpart F, § 84.53 (a) and Subpart H, § 84.95 (a) and (b)

 Requirement:

Service time will be measured while the apparatus is operated by a breathing machine as

described in § 84.88. The open-circuit apparatus will be classified according to the length

of time it supplies air or oxygen to the breathing machine. Classifications are listed in § 

84.53.

Procedure:

A breathing machine with a 622 kg-m/min cam operating at 24 RPM with a 40 liter per

minute flow rate was connected to an anthropometric head for cycling. A pressure tap in the

head was connected to a transducer which in turn connects to a strip chart recorder for

determining the pressure in the facepiece. The breathing machine runs until the inhalation

portion of the breathing curve falls below the minimum requirement.

 Results: Tested on December 8, 2016. The SCBA met the test requirement.

 Test Notes:

The measured service time (adjusted to correspond with the recorded breathing cycles) 

was more than the rated service time of 30 minutes. The PASS unit functioned during the

test. The SCBA did go negative on inhalation, and it did not maintain positive pressure in 

the facepiece throughout the test.

Pass/Fail: Pass

 4. GAS FLOW TEST – NIOSH Standard Test Procedure Number 123, 42 CFR Part 84

 Reference: Subpart H, § 84.93 (b) and (c)

 Requirement:

The flow from the apparatus shall be greater than 200 liters per minute when the pressure in 

the facepiece of demand apparatus is lowered by 51 mm (2 inches) water column height

when full container pressure is applied. Where pressure demand apparatus are tested, the

flow will be measured at zero gage pressure in the facepiece.

Procedure:

A pressure tap in the anthropometric head was connected to a manometer for determining

when the pressure inside the facepiece is at zero. A mass flow meter was connected in line 

between the anthropometric head and an adjustable vacuum source to measure flow. The 

SCBA cylinder was replaced by a test stand which was adjusted initially to full cylinder

pressure. The vacuum source was adjusted during the test to maintain the desired pressure

inside the facepiece. Once the proper facepiece pressure stabilized, a flow reading was 

recorded. The procedure was then repeated with the test stand adjusted to 500 psi.

Results: Tested on December 13, 2016 The SCBA met the test requirement. The bypass 

appeared to function normally.
