ABSTRACT A supplied-air hood constructed by Safety and Supply Company, Seattle, Washington, was evaluated for personnel protection in high concentrations of either dust, vapor, or radioactive particulates. He hood was evaluated in a test atmosphere of iioctyl-phthalate (DOP) polydispersed aerosol, with human subjects wearing the hood. The hood was evaluated by a series of exercises testing for noise levels, temperatures, commanications, and the degree of protection provided. Recommendations for use and construction are made.

DOUBLE BIBBED SUPPLIED-AIR HOOD

1. INTRODUCTION At the request of Argonne National Laboratory-West (ANL-W); Safety and Supply Company, Seattle, Washington; and EG&G Idaho, Inc., the supplied-air hood was evaluated for effectiveness in a possible toxic atmosthere. The hood was evaluated, using a quantitative person test and polydispersed atrnosphere procedures as outlined in the U.S.

Bureau of Mines / National Institute for Occupational Safety and Health Approval Schedule 30 CFR Part 11(see Appendix A).

This evaluation was based on the Tyre C, loose-fitting, and supplied-air respirator classification. This consists of:

(1)

Compressed Gas Association (CGA) Grade D or better source of breathing air (2)

Manifold (3)

Air hose (4)

Detachable couplings (5)

Control valve orifice s

(6)

Attachment of air hose to the wearer (7)

Hood.

This type of double bibbed supplied-air hood (Figure 1) was not evaluated for significant damage occurring to the respiratory device due to. abrasive or chemical operations.

The requirements that were used for performance ciiteria as % 30 CFR Part !! were:

3 3

(1)

Air flow of 0.73 m / min (4 cfm) and m / min (15 cfm),

3 and operating flow of 1.7 m / min (6 ct.s for evaluating. Air flow rates were not corrected for 1574 m (5000 ft) above sea level (2)

Operating maximum sound level not to exceed 80 dba (3)

Maximum airline pressure of 125 psig at point of coupling attachment (4). Hose length 30.5 m (100 ft) for evaluation of 7.6 m (25 ft) multiples not exceeding 91.5 m (300 ft) 1

The test chamber (Figure 3) conditions were established by using an Air Techmques, Inc., (ATI) Model TDA-50A, Man Test Self-Contained Instrument for generation and i

evaluation of the test atmosphere. The test atmosphere was approximately a 3

25 to 30 mg/m concentration of polydispersed air-generated dioctyl-phthalate (DOP) with a medium diameter of 0.6 to 0.7 pm. The test hood sample flow rate near the test subjects' 3

breathing zone was 0.071 m,-hr (25 cfph). The aerosol concentration in the test chamber and hood was evaluated with an ATI forward light scattering photometer.

8. NOISE MEASUREMENTS The noise measurements were made using a General Radio Company Sound Level Meter. The pickup receiver was placed from 0.025 ic 0.076 m (1 to 3 in.) from the test subject's right ear. The test chamber's noise background reading was 68 to 71 dBA.
9. PROTECTION FACTOR I

The calculation of the effective protection factor was based on the following formula, which is the reciprocal of the penetration reading (Appendix B).

Protection Factor = Concentration in Test Chamber.

Concentration in Test Hood The calculated average protection factor was >5000. The test subjects had a maximum protection factor >9000, with a minimum protection factor >2000. The higher protection factors are a combination of hood design, proper procedures, and good techniques.

1 For protection factors that have been established see Appendix B. These protection l

factors are from the National Institute for Occupational Safety and Health, Publication l

76-189, "A Guide to Industrial Respiratory Protection.

10. RECOMMENDED PROCEDURE FOR USE The information in Table VI is the recommended procedure to obtain the maximum protection factor. The donning is only a recommendation and was found to be the most effective in actual hood evaluation.

I1. CONCLUSIONS The Safety and Supply Company supplied-air hood affords good protection from most airborne toxicants. The evaluation shows that the hood could be used in areas where most airborne contaminants could greatly exceed the maximum permissible levels.

Proper procedures and techniques for use of the hood must be followed. They improve protection at low air flow and noise levels. The degec of possible skin contamination is reduced with the double bibbed hood. The low hood noise level is an aid in good communication.

23

The 6 valuation indicates that the hood will provide protection against simple particulate radioactive material and objectionable odors. No consideration was given to chemical and acid exposure to the hood. The hood, in certain areas can be used under oxygen deficient conditions. Such conditions occur in many operations. However, proper ventilation, engineering control, containment, and substitution of material must be considered as the preferred alternatives.

By testing and evaluation, the original 1 ood has been greatly improved. It is relatively inexpensive. Improving the design and use o'the hood for personnel protection will be a continuing program.

respirator and an SCBA.

l 59

~

Exception:

Combination supplied-air respirators, in pressure-demand or other positive pressure mode with an auxiliary self-contained air supply, and a full facepiece, should use the PF for pressure-demand SCBA.

NOTE: Table is not to be reproduced without the accompanying footnotes.

[a] The overall protection afforded by a given respirator design (and mode of operation) may be defined in terms of its protection factor (PF).

The PF is a measure of the degree of protection afforded by a respirator, defined as the ratio of the concentration of contami-nant in the ambient atmosphere to that inside the enclosure (usually inside the facepiece) under conditions of use.

Respirators should be selected so that the concentration inhaled by the wearer will not exceed the appropriate limit.

The reconsnended respirator PF's are selection and use guides, and should only be used when the employer has established a minimal acceptable respirator program as defined-in Section 3 of the ANSI Z88.2-1969 Standard.

[b] In addition to facepieces, this includes any type of enclosure or covering of the wearer's breathing zone, such as supplied-air hoods, helmets, or suits.

l

[c]

Includes dusts, mists, and fumes only.

Does not apply when gases I

or vapors are absorbed on particulates and may be volatilized or for particulates volatile at room temperature.

Example:

Coke oven emissions.

[d] Any single-use dust respirator (with or without valve) not specifi-cally tested against a specified contaminant.

[e] Single-use dust respirators have been tested against asbestos and cotton dust and could be assigned a PF of 10 for these particulates.

[f] Dust filter refers to a dust respirator approved by the silica dust test, and includes all types of media, that is, both nondegradable mechanical' type media and degradable resin-impregnated ^ wool felt or combination wool-synthetic-felt media.

[g] Fume filter refers to a fume respirator approved by the lead fume test. All types of media are included.

[h] High-efficiency filter refers to a high-efficiency particulate respirator.

The filter must be at least 99.97% efficient against O.3 pm 00P to be approved.

[i] To be assigned, based on dust or fume filter efficiency for specific l

contaminant.

l e

60 I

n

~

[j] For gases and vapors, a PF should only be assigned when published test data indicate the cartridge or canister has adequate sorbent f ",

efficiency and service life for a specific gas or vapor.

In addition, the PF should not be applied in gas or vapor concentrations that are:

(a) immediately dangerous to life, (b) above the lower explosive limit, and (c) cause eye irritation when using a half-mask.

[k] A positive pressure supplied-air respirator equipped with a half-mask facepiece may not be as stable on the face as a full facepiece.

Therefore, the PF reconnended is half that for a similar device equipped with a full facepiece.

[1] A positive pressure supplied-air respirator equipped with a full facepiece provides eye protection but is not approved for use in atmospheres innediately dangerous to life.

It is recognized that d

the facepiece leakage, when a positive pressure is maintained, should be the same as an SCBA operated in the positive pressure mode.

How-ever, to emphasize that it basically is not for emergency use, the PF is limited to 2000.

j

[m] The design of the supplied-air hood, suit, or helmet (with a minimum of 6 cfm of air) may determine its overall efficiency and protection.

1 For example, when working with the arms over the head, some hoods draw the contaminant into the hood breathing zone.

This may be overcome by wearing a short hood under a coat or overalls.

Other limitations specified by the approval agency must be considered before using in certain types of atmospheres.

[n] The SCBA operated in the positive pressure mode has been tested on a selected 31-man panel and the facepiece leakage recorded as less than 0.01% penetration.

Therefore, a PF of 10 000+ is recommended.

At this time, the lower limit of detection 0.01% does not warrant listing a higher number. A positive pressure SCBA for an unknown cot. centration is recommended. This is consistent with the 10 000+

that is listed.

It is essential to have an emergency device for use in unknown concentrations. A combination sepolied-air respirator in pressure-demand or other positive pressure mode, with auxiliary self-contained air supply is also recommended for use in unknown concentrations of contaminants immediately dangerous to life.

Other limitations, such as skin absorption of HCN or tritium, nust be considered.
