PPE CASE

Personal Protective Equipment Conformity Assessment Studies and Evaluations

Evaluation of a Self-Contained Breathing Apparatus Involved in a 

Near Miss in the Fire Service

Rock Creek Idaho Fire Department Request for 

a Sperian TITANT M 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 one selfcontained breathing apparatus (SCBA) identified as a Sperian 

TITANTM, 45 minute, 4500 psi unit. 

This SCBA status investigation was assigned NIOSH Task 

Number 21014. The Rock Creek Fire Department was advised 

that NIOSH NPPTL would provide a written report of the 

investigation and any applicable test results.

The SCBA unit was delivered to the NIOSH facility in 

Morgantown, WV on August 31, 2016. The unit was 

transported to Lab H1513 for secured storage. The SCBA unit 

was removed from secured storage for inspection on October 

25, 2016 and was placed back into secured storage until the

performance testing was conducted on November 9, 2016.

 

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 were conducted by Jeremy Gouzd and Karis Kline of the Morgantown 

Testing Team (MTT), Evaluation and Testing Branch, National Personal Protective Technology

Laboratory, National Institute for Occupational Safety and Health, located in Morgantown, West 

Virginia.

SCBA Inspection

The unit was removed from the packaging in Lab H1513 and inspected on October 25, 2016 by 

Jeremy Gouzd and Karis Kline of the Morgantown Testing Team at NPPTL. The unit was identified as a 

Sperian TITANTM, 45 minute, 4500 psi unit with NIOSH Approval Number TC-13F-0809CBRN and as the 

unit submitted by the Rock Creek Fire Department. The SCBA was visually examined, component by

component, in the condition received to determine 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 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) Air Flow Performance requirements of NFPA 1981, Standard on Open-Circuit Self-Contained

Summary and Conclusions

An SCBA unit was submitted to NIOSH NPPTL by the Rock Creek Fire Department for evaluation 

following a request by telephone. The SCBA unit was delivered to NIOSH on August 31, 2016 and 

extensively inspected on October 25, 2016. The unit was identified as a Sperian TITANTM 45 minute, 

4500 psi unit with NIOSH Approval Number, TC-13F-0809CBRN. A corresponding facepiece was 

provided with the unit. The unit did not show any sign of heat damage and appeared to be in near

new condition. An empty cylinder was delivered with the unit, with the valve open. The mask 

mounted regulator (MMR) and sealing areas of the unit were clean. The locking assembly functioned, 

and the inside flange had no to minimal scratching. The NFPA approval label on the unit was present

and legible. The personal alert safety system (PASS) functioned. 

In light of the information obtained during this inspection, NIOSH proposed no further action on its 

part at this time. The SCBA unit was returned to secured storage pending return to the Rock Creek 

Fire Department.

If this 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 at least an annual basis, at a minimum.

Actions to be taken by the Fire Departments with SCBAs Involved in 

an Incident

 Any SCBA unit involved in an incident may not be placed back in service until the SCBA has been

repaired, tested, cleaned and any damaged components replaced and inspected by a qualified

service technician, including such testing and other maintenance activities as prescribed by the 

schedule from the SCBA manufacturer. 

 For all SCBA units, even those not involved in an incident, must undergo a flow test on at least

I. Background

On August 31, 2016, an SCBA unit from the Rock Creek Fire Department was delivered to the

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

packaging in Lab H1513 and inspected on October 25, 2016 by 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 

NIOSH-approved configuration. The unit was identified as a Sperian TITANTM, 45 minute, 4500 

psi unit with NIOSH Approval Number TC-13F-0809CBRN, and as the unit submitted by the 

Rock Creek Fire Department. The visual inspection process was documented with 

photographs.

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 connected to a strip chart recorder for determining the pressure in the facepiece.
 TN-21014 Rock Creek, Idaho Fire Department – Status Investigation Report 13

Results: The unit was tested on November 9, 2016 and met the test requirement. The

heads-up display (HUD), remote gauge, and donning switch functioned normally.

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 connected to a strip chart recorder 

for determining the pressure in the facepiece. The breathing machine was run until the

inhalation portion of the breathing curve fell below the minimum requirement.

Results: Tested on November 9, 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 45 minutes. The PASS unit 

functioned during the test. The SCBA did not go negative on inhalation but maintained 

positive pressure in the facepiece at the same level.

 Part 84 Reference: Subpart H, § 84.91 (d)

Requirement:

The static pressure (at zero flow) in the facepiece shall not exceed 38 mm. (1.5

inches) water column height.

Procedure:

The facepiece was fitted to an anthropometric head for testing. A pressure tap in the

head was connected to a calibrated manometer. Full cylinder pressure was applied to 

the unit at zero flow and a reading from the manometer was recorded.

Results: Tested on November 9, 2016. The SCBA met the test requirement.

Facepiece Static Pressure:

(inches of water column) 0.78

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 reaches 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 November 9, 2016. The SCBA met the test requirement. The bypass

appeared to function normally.

Requirement:

Each remaining service life indicator or warning device shall give an alarm when the 

remaining service life of the apparatus is reduced to a minimum of 25 percent of its
 TN-21014 Rock Creek, Idaho Fire Department – Status Investigation Report 16

rated service time or pressure.

This requirement is modified under § 84.63(c) as follows: For apparatus which do not

have a method of manually turning off remote gage in the event of a gage or gage line

failure the remaining service life indicator is required to be set at a minimum of 25% of 

the rated service time or pressure.

Procedure:

A calibrated gauge was connected in line between the air supply and the first stage

regulator. The unit was then allowed to gradually bleed down. When the low air alarm

was activated, the pressure on the gauge is recorded. This procedure was repeated six

times. The average of the six readings was calculated and recorded.
