RSSP-IRATOR WORKPLACE PROTECTION FACTORS FOR ASBESTOS (Haskell Laboratory Report No. 462-84 ? MR-SSS'J-OOl)
SUMMARY AND BACKGROUND
Workplace protection factors for alastomaric and single usa half-fact respirators wars measured during asbestos removal operations. The operations consisted of asbestos removal from a ceiling (fire proofing) and removal of pipe insulation. The use of water/surfactant solutions to spray fire proofing and insulation resulted in conditions of high humidity for indoors operations. Out-of-doors operations were also under high humidity conditions since light rain occurred on two of four days of sampling. Temperatures for both operations were in the 65-35*F range.
The respirators were used in the context of a respirator program that followed the guidance in 29 CPX 1910.134 and ANSI Z88.2 (1980) including proper respirator selection and fit testing. A total of seventeen volunteers participated in the study, one or two workplace protection factors were determined for each respirator for which the fie test had been passed.
The respirators tested were:
e one successfully fitted elastomeric facepiece respirator chosen for comfort from six respirators (MSA Comfo II and Survivair 2000 brands - small, medium and large sizes). These respirators were tested using dust, fume and mist and high efficiency filters.
e Each of three disposable respirators successfully fitted (3M 9910, 3M 0710 and American Optical R 1050).
e A successfully fitted North 7700 elastomeric facepiece respirator, chosen from the small, medium or large size facepieces.

In addition two workplace protection factor measurements ware mad# for a self-contained breaming apparatus operated in the pressure-demand mode.
Results show that all respirators tested, reliably provide workplace protection factors of ten or greater, except the AO RIO50, which reliably provides a protection factor of five or
greater, based on estimates of lower 5th percentile. These results are consistent with information supplied to the OSHA asbestos record by Los Alamos National Laboratory which reported on the.penetration of asbestos through respirator filter media. 1
Results for the self-contained breathing apparatus suggest that it may not provide appreciably better protection than the two better disposable respirators and the elastomeric facepiece respirators, though it presents a considerable stress and hazard
of falling because of it's weight and awkwardness. Myhre et and Ravenhave shown that pressure-demand respirators
do not maintain positive pressure inside the facepiece when workloads are increased from rest conditions. This may explain, in part, why the pressure-demand and self-contained breathing apparatus did not provide superior protection.
PROCEDURE
Prior to testing, each person was trained in ths selection and fit testing of respirators using the National paint and Coatings Association Training Program*4>. Each was then fit tested using the saccharin fit test14'. Pit test results are given in Table V. Respirators selected for use ar.d vendors are listed in Table I.
Two Individuals war* also tralnad In us* oC a pcassupa--demand
self-contained breathing apparatus. Fit testing was not done, as it is not required for pressure-demand equipment per the ANSI Z88.2 (1980) standard.
During sample collection, each participant was observed continually to ensure that the sample train remained intact and did not Interfere with the respirator seal on the face, and to note occurrences which might have affected respirator performance, such as movement of the respirator on the face. The participants were very busy with their work activities and soon ignored the presence of the researchers.
AIR SAMPLING AND ANALYSIS
To determine the workplace protection factors, concurrent samples were taken from inside the respirator (in-mask) at nose
level and outside the respirator at the lapel (lapel). Closed-face Olasrock (#1503) cassette filter holders fitted with half inch extenders and probes developed by NIOSB13' were used for both the in-mask and lapel samples. The sample probes are specially designed to minimize the loss of particulates. The
cassettes contained 0.8 urn, 25mm cellulose ester filters.

The sample train* wr calibrated bsfor* and after taking each sample using a mass flow meter. The mass flow meter was calibrated against a bubble flow meter at the beginning and end of tne study. A flow rate of 2 Lpm was used for the in-mask samples. Lapel samples were taken at 0.5-1.0 Lpm to avoid overloading.
Samples were collected for a one- to two-hour period. Each sample represented a single wearing of the respirator.
Fiber counts were done per NIOSH method PsCAM 239{fi* (phase contract microscopy), except that the triacetin/acetone mounting method was used as described in NIOSH method 7400'7'. counting was done according to the PICAM 239 rules (the "A" counting rules in method 7400). Five hundred fields were counted for in-mask samples to increase analytical sensitivity. All analyses were done by one counter who participates successfully in the American Industrial Hygiene Association's Proficiency Analytical Testing quality assurance program. Concentrations were calculated from the actual number of fibers counted (even if fewer than 50 fibers were counted) per the formulas in the NIOSH method.
NIOSH method P&CAM 239 reports a coefficient of variation of' 0.12 which applies to lapel samples in this study. He estimate that the coefficient of variation for the in-mask samples is 0.4 at the median in-facepiece concentration and fiber count (Table III).
Transmission electron microscopic analyses were also done on selected samples to obtain data on small fiber penetration and size distribution.
All tield and analytical data are retained in the HR-5557
file.
SAMPLING AND ANALYSIS METHOD VERIFICATION
In-mask sampling required use of elosed-faee filter cassettes. He used Glasrock *1505 25mm filter cassettes which have a unique tapered design for the outlet and a.half inch extender which improves.the deposition patterns'*'. To minimize sample loss, the NIOSH'9' probe was used to withdraw in-mask samples.
To eliminate possible bias, the same closed-face/probed cassette was used for both in-mask and lapel samples. To document whether concentrations determined from elosed-face/probe cassette sampling differed from open-face sampling, twelve area samples were taken using both methods. Results are.compared in Table II with student's t and variance Ratio tests' '. The two sampling methods were found to give similar results with no
significant bias or difference in precision.

RESULTS AND DISCUSSION
Transmission electron microscopic analysts were dons on four lapsl samples by Elsctron Microscopy Service Laboratories, Inc., Camden, Sew Jersey. The resultant distributions of fiber diameters and lengths are shown in Figures 1 and 2. Fiber diameters and lengths covered a wide range.
The overall median concentrations of fibers for in-mask and
lapel samples are given in Table III. The median number of
fibers counted for in-mask (500 fields counted) and lapel (<100
field counted) samples are also given in Table III.

Cumulative distributions, geometric means, geometric standard
deviations, best estimates of 5th percentiles and lists of
workplace protection factors are given in Figures 3 through 8 for each respirator. The distributions of workplace protection factors were found to be approximately lognormal for all respirators studied. Therefore, logs were used for the plots,
geometric means are reported as the proper measure of central tendancy and geometric standard deviations are reported as the proper measure of variability. Best estimates of 5th percentiles represent the workplace protection factors that most (95%) respirator users are expected to obtain from each respirator.
Distribution plots and geometric standard deviations include variability from the sampling and analytical method as well as from the workplace protection factors. The unavoidable inclusion of the sampling and analytical variability in the plots results in best estimates of 5th percentiles which are conservative (lower than actual). This should be considered in evaluating results.
workpiece protection factors were determined for a self-
contained breathing apparatus for two individuals. Results are reported in Table IV.
Table V gives geometric means, geometric standard deviations, best estimates of the 5th percentile, and ratios of participants passing the fit test for each respirator studied. A Bonferronl'9' test for differences (pO.OS) was done and results are given in Table V. workplace protection factors for the 3M 9910 were found to be significantly higher than those for the AO R1050. No other significant differences were found. The importance of doing a fit test is apparent from the fit test
results in Table v.
The relatively low results for the AO R1050 are likely due to poorer filter efficiency for asbestos, reported by Dr. Ortiz of Los Alamos National Laboratory11'.

The unexpected comparability of the results from the 3M disposable respirators, and elastomeric facepiece respirators with both dust, mist and fume filters and high efficiency filters may be explained by several factors. First, because the filter efficiency is high (^99.9%), the limiting factor in performance of the respirators is likely face fit, not filter efficiency (except for the AO R1050 as noted above). Since the same fit test was used to select good fitting respirators for the study, comparable face fit results would be expected. In addition, the researchers noted a tendency for elastomeric respirators to slip around when some wearers' faces became wet with the water/surfactant spray. This did not occur with the disposable respirators because their fibrous material of construction clung to the skin.
It is particularly noteworthy that the workplace protection factors for the self-contained breathing apparatus were not superior to the better disposable and elastomeric respirators. Myhre'2 and Raven13 have shown that at workloads exceeding approximately 35% of maximal aerobic capacity pressure inside the facepiece of pressure-demand type respirators does not remain positive with respect to the surrounding atmosphere. This would provide an opportunity for airborne asbestos to be drawn into the facepiece.
The volunteers who wore the self-contained breathing apparatus complained of stress and discomfort due to its weight and bulk. Movement and balance were difficult and one volunteer almost fell from a step ladder as a result. Based on their observations, the researchers believe that routine use of self-contained breathing apparatuses for asbestos removal would likely result in injuries, in view of the large amount of climbing involved. Certainly, acceptance will be much poorer than for the other respirators studied, due to discomfort which would discourage respirator use.
Transmission electron microscopic analysis results were also used to determine workplace protection factors for thin fibers (Table VI). Results for small diameter (<0.2um) fibers do not appear to differ from those for large diameter (>0.2un) fibers, for 5 um or longer lengths. Thus, results for fibers visible with the phase contrast method (>0.2um diameter) appear to be representative of those for smalTer diameter fibers for the 3M 8710 and 9910, and for elastomeric respirators with dust, fume and mist and high efficiency filters.
CONCLCJSIOHS
1. All respirators tested provided protection against asbestos. The American optical RIO50 disposable respirator reliably provided workplace protection factors of 5 or greater. The 3M 9910, 3M 8710, and elastomeric half-face respirators with both dust, fume and mist and high efficiency filters reliably provided workplace protection factors of 10 or greater.
DOT 0933726
DU 036292
2. 'jse of higher efficiency filters did not appear to improve cne workplace protector factors of the elastomeric respirators.
3. workplace protection factor measurements for a pressure demand self-contained oreatnmg apparatus were not significantly higher than tnose for the better disposable and elastomeric respirators. Comments from the test volunteers and observations indicate that acceptance of the selfcontained breathing apparatus would be poorer than that of the other respirators tested, in addition, it presents a significant risk of tripping or falling, where removal work requires climbing ladders and working from scaffolding.
4. Transmission electron microscopic analyses suggest that for fibers longer than 5 ura, the overall workplace penetration of small diameter (<0.2um) fibers is not higher than that of larger diameter fibers for the 3M 3710 and 3M 9910 disposable respirators nor for elastomaric respirators with dust, fume and mist or high efficiency filters.

RESPIRATOR WORKPLACE PROTECTION fACTORS FOR ASBESTOS SUMMARY AMD BACKGROUND
workplace protection factors for elastomeric and single use half-face respirators were measured during asbestos removal operations. The operations consisted of asbestos removal from a ceiling (fire proofing) and removal of pipe insulation, copious use of water/surfactant solutions to spray fire proofing and insulation resulted in conditions of high humidity for in-doors operations. Out-of-doors operations were also under high humidity conditions since light rain occurred on two of four days of out-of-doors sampling. Temperatures for both operations were in the C5-85*P range.
The respirators were used in the context of a respirator program that followed the guidance in 29 CPU 1910.134 and ANSI 288.2 (1980) including proper respirajtqg, selection and fit testing. A total of seventeen volunteer* participated in the study. One or two workplace protection factors were determined for each respirator for which the fit test had been passed.
The respirators tested were< e one suecesefully fitted elastomeric facepiece respirator
chosen for comfort from the two brands (H8A comfo il and Survivair 2000 - 3 sixes each). These respirators were tested with type T (dust, fume and mist) and type H (high
efficiency) filters.

Each of the three disposable respirators successfully fitted (3M 9910, 3M 8710 and American Optical R 1050).
e 'one successfully fitted (of three sizes) North 7700 elastomeric facepiece respirator.
in addition two workplace protection factor measurements were made for a self-contained breathing apparatus operated in the pressure-demand mode.
Results showed that all respirators tested reliably provided workplace protection factors of ten or greater except the AO R1050 which reliably provided a. protection factor of five or greater. Results for the self-contained breathing apparatus suggest that it may not provide appreciably better protection than the better disposable and elastomeric facepiece respirators, though It puts considerable more physical stress on the wearer due to its weight and bulk.
PROCEDURE
Prior to testing, each person was trained in the selection and fit testing of respirstors using the Rational paint and Coatings Association Training program*!). Each was then fit tested using the saccharin fit test(1>. Respirators selected for use by participants are listed above and in Table X.

RESULTS A^D DISCUSSION
Transmission slsctron microscopic analyses were mads on four lapsl samples to document the distribution of fiber diameters and lengths. Distributions are shown in Figures 1 and 2. Fiber diameters and lengths covered a wide range.
The overall median concentrations of fibers for in-mask and lapel samples are given in Table III. The median number of fibers counted for in-mask (500 fields counted) and lapel (100 field counted) samples are also given in Table III.
Cumulative distributions, geoswtric means, geometric standard deviations, best estimatss of 5th percentiles and lists of workplace protection factors are given in Figures 3 through 8 for all respirators. The distributions of workplace protection factors were found to be approximately lognormal for all respirators studied. Therefore, logs were used for the.plots, geometric means are reported as the proper measure of central tendency and geometric standard deviations are reported as the proper measure of variability. Distribution plots and geosMtric standard deviations include variability from the sampling and analytical method as well as from the workplace protection factors. This should be considered in evaluating results.
DUF 0933756
DU 036314
Best estimates of 5th percentiles represent the workplace
g
protection factors that most (9St) respirator users are expected to obtain from each respirator. The unavoidable inclusion of the sampling and analytical variability in the plots results in best estimates of 5th percentiles which are conservative (lower than actual).
Workplace protection factors were determined for a selfcontained breathing apparatus for two individuals. Results are reported in Table IV.
Table v gives geometric means and standard deviations for all respirators studied, A Bonferroni(S) test for differences (p*0.05) was done and results are given in Table v. Workplace protection factors for the 3M 9910 were found to be significantly higher than those for the AO R1050. No other significant
differences were found. The researchers noted a tendency for elastoaerle respirators to slip around when mm wearers' faces
became wet with the water/surfactant spray. This did not occur with the disposable respirators because their fibrous material of construction clung to the skin. This msy explain the unanticipated comparability of the results for the 3M disposable respirators aad the elastomeric respirators. The relatively low results for the AO R1050 are likely due to poorer filter efficiency for asbestos, reported by Dr. Ortis of Los Alamos National Laboratory**1.

It is^particularly noteworthy that tha workplace protaction factors for tha self-contained braathing apparatus were not suparior to tha battar disposable and alastonaric rasplrators. Tha voluntaars who wora tha self-contained braathing apparatus conplainad of strass and discomfort dua to its waight and bulk. Movement and balanca wara difficult and ona voluntaar almost fall from a stap laddar as a rasult. Basad on thair observations, tha rasaarchars baliava that routina usa of salf-containad braathing apparatusas for asbestos removal would likely result in injuries, in view of tha large amount of climbing involved. Certainly, acceptance will be much poorer than for the other respirators studied, due to discoaifort which would discourage respirator use.
Transmission electron microscopic analyses were done on ln-mask and lapel samples. Resultant workplace protection factors are reported in Table VI. Results for small diameter (<0.2um) fibers do not appear to differ from those for large (>0.2um) diameter fibere, for s urn or longer lengtha. Thus, results for fibers visible with the phase contrast method O0.2un diameter) appear to be representative of those for smaller diameter fibers 09 um length) for the 3M B710 and 9910, and for elastomeric reepiratore with type P and M filters.

CONCLUSIONS
1. All respirators tested provided protection against asbestos. Tbs'American Optical R1050 disposable respirator reliably provided workplace protection factors of 5 or greater. The 3N 9910, 3N 8710, and elastomeric half-face respirators with both Type P and Type H filters reliable provided workplace protection factors of 10 or greater.
2. use of higher efficiency (type H) filters did not appear to improve the workplace protector factors of the elastomeric respirators.
3. workplace protection factor measurements for a pressure demand self-contained breathing apparatus were not significantly higher than those for the better disposable and elastomeric respirators. Comments from the test volunteers and observations indicate that acceptance and safety of the self-contained breathing apparatus will be poorer than that of the other reepirators tested.
4. Transmission electron microscopic analyses indicate that overall workplace penetration of small diameter (<0.2un) fibers (longer thanS urn) is not discernibly higher than that of larger diameter fibers for the 3M 8710 and 3H 9910 disposable respirators nor for elastomeric respirators with Type p or H filters.

SSO INDUSTRIAL AND LABOR RELATIONS REVIEW
Data
Thil malycs it based on data collected as pan oT a reudy of 995 ubestoa-related deaths that occurred between 1967 and 1977 among tnembcn of the International Asaotiitioa of Heat and Fran Intuiaton
and Asbestos Workers, AFLCIO and CLC.' As pan of that study. 792 survives* from the United Sute* and Canada were interviewed in 1990 to determine the economic consequence* of the deaths.* We excluded interview* with Canadian citizens
from the present analysis because of the differences between the Canadian and UA compensation systems. We also excluded interview* with survivor* other than the deceased^ widow and interviews with wid ow* whose husbands died after the expected end of their work life. Remaining after them exclusions were interviews with 560 widows.
Interview questions probing the eco nomic consequences of the deaths focused on the cash income and later compensatory payments received by the widows. Queries about the amount and source of cash incomes were only for the year 1979, so minimise recall error; but questions about
lump-sum payments from workers' com pensation and tort settlements asked about all yean 1967-79.* Wr can aanune that recall error in reports of lump-sum paymenu is low because the events surround ing the payment awards (such at court sens
and woeket*'compensation agency rulings)

*"* nual income lease* of survivor* were calculated from the time of death to the end of the worker * expected work life. Because our mow accurate data on com pensation payments are those for 1979. we emphasize the results for 249 widows whose husbands' expected work lives extended at Jexst to 1979. and we present only limited ratultx for the 911 survivor* of men whose work lives were expected to end before 1979.

The radonale for the rwo-thiids standard
is ambiguous, but its general acceptance among policymaker* makes it an important criterion touacin comparing compensation tchemea.
In principle, common-taw damage
awards should equal the mm of wage loas, medical costs, and compensation for pain
and suffering. The objective of the com mon law it to return successful litigants to the sure of well-being they would have enjoyed had their spouses not died. Since our tstimate* equal only wage income losses, our replacement ratios far tort awards are higher than the true ratios. As a standard efadequacy for our results, we use a replacement ratio equal to one.
Another important measure of adequacy it the proportion of survivors who receive benefits. Workers' compensation laws promise universal coverage for workrelated deaths. In theory; therefore, aB the survivors mdfad here were eligible far woeken' compensation. Common law re quires that each plaintiff prove his or her eligibility, however, and elements ef proof vary among jurisdictions and involve isms of fact about which we do not ham information. We therefore cannot define a general standard for common-law coverage
of the survivors. The standards that we have defined here
approximate only the moat general objec tives of the current forms of compensation. Our inabiBty to be more precise reflects the
variation among workers' compensation
bus and the confusion that surrounds the
purposes of the current system of oompea-

not a concern in these cue* By deducting taxes hem our loti estimates, we avoid eomparinf nentaxabie benefit* before-tax wag*a. One can atfue. howerer,
that worker*' compensation should be evaluated afainat the rwo-thirda itandard rather than aome abaolute measure of adequacy.
Because these mult* represent net lorn* in the year that is a median ofsix yean after the worker's death, they cannot be directly evaluated by the two-thirds standard (the ratio of benefits at the time of the award to gross waigsa prior to death). Instead, we perform the following calculation, which approximates that kind of evaluation. Since workers' compensation benefits ate usually paid in installments of equal amounts, benefit* in 1979, for most wrvivors, should have been equal to the annual amount awarded after the worker's death. We evaluate the two-thirds stan dard. therefore, by comparing 1979 bene fits to the deceased's wages in the year ofhis death. The median ratio ofbenefits to gran
wages prior to death is If percent." These results show that whether we
consider the 1979 dam or the two-thirds standard, worker's compensation payments are not adequate. This conclusion it reinforced by the (act that our remits as* based on data for only thorn widow* who received such payment*. When the loam of widows who did not weave workett' compensation arc also included in the analysis, the replacement redo* are sub stantially lower.
Only 39 (19 percent) of the 949 widows received workers' compensation payments
in 1979. A larger aataber af widows had received payments before 1979. bur these payments had triad Of the B49 widow*. 12S filed werkerf compenastien claims;

Only 39 of the original 109 recipients were still receiving payments in 1979. All but two of the 46 lump-sum payments were consumed by loans before 1979. and 23 of the (2 benefits paid in iiwtallmencs bad ended before 1979. The exhaustion of workerli compensation benefits before lames end has also been observed among worken disabled by accidental injuries. Studies show that. mmeraBy. the shorter the period of low, the higher the rate of replacement by worken' compensation.*
In sum. the results show that the standard ofunivenal coverage is aot nearly met. Whether the failure is that ofworken' compensation scherew or ocher influences is not dean Most of the widows who filed claims received payments, but only onehalf of the widow* filed. An analysis of the reasons for this low rate of fifing is therefore critical to evaluating the adequacy of coverage, hut such an analjew is beyond the scope of this study

Ion income replaced all the lone* of II of the other IS widow* who received ton income in 1979." The common law, therefore, utiafvea its standard of adequacy. The adequacy of compenaadon does vary,
however; with the time at which benefit! and laaaea are compared.
AD these II widowi, except for one whoae
imputed income was loss than her net less is 1979, had capital left to invest at the end of that year. In the following year; eight of the 11 tan recipients received an imputed income sufficient to replace their 1*90 tomes. The other three widows would have exhausted their ton award capital during 1980. The pattern of the gradual exhaus tion of lump sum awarai is me that deserves mot* attention as an important pan of the adequacy of compensaaoa.
The replacement ratio* for ton income in 1979 do not reflect the losaes of unsuccessful plaintiffs or of survivors whose
lump sum was consumed before 1979. Of 44 widows who filed ton suits. SC received an sward or a settlement. Only IS of the SC (Table 1) received income in 1979 from their ton suit. Unfonunately, the data on ton tuits are incomplete. Six widows said their suit was successful but did not repon benefits, and twelve suits were undedded at the time of interview. It is dean however that few suns were filed. As fat the earn of failure to file workers' compensation damn, the reasons fee this behavior are am dear. The low raus of filing for (on and woriten' compensation do not suppen the suggtnion aometimas made that weeken tubednice ton claims far workers' compen sation.

failure ofboth workers' cempensatioa plans and the common law. Benefits from chose
two sources typically replaced leu than SO percent of loans (Table 1). Widows who
combined them benefits with payments from other sources, however, were the only ones whose compensation exceeded their loan.
The amount of aodsl insurance benefits varies with the time at which they ire measured. Eligibility far sodal security Ktvivon' benefits is conditional on whether there at* any dependent children in the borne or on the age of the widow. Widows receive no benefits between the time their children come oflegal age and the time the
widows teach mheneiu age. The dau on private pensions do not separate retirement cum survivors' benefits.

the mean is sheared toward below-aversge

--itmr that workers' compensation bene fits in 1979 for 140 widows who received
benefits equaled the annual amount paid nee the time of their husbands' death.
Annual income from lump-sum payments was calculated from the ome of death to 1979 in the manner described in the methoda wetion. The ratios of the sum of benefits (ham the time of death to 1979) to the sum of lames (annual kmes equal scro after the expected end of the work lilt) art
priMtued in Tkbte S. Tht time dfctribuooa
of social inauraace and paaston benefita cannot be approximated, m replacement ratios are estimated only for tbe occupational-illneai programs.
Since the pro cohorts sf uddotrs differ in
aae and mirage lease, a comparison ofthe'1 ratios to Hitts I with those in Tkbte 1 only appiiwlmittf the df*a of pon-work-lift
bsncfisoa the adequacy of compensation. The rcpfacahntnc ratios Car woeken1 comperhation in Tkbte S (column S) differ froth1 *

art lower than thoae for the cohort having a
work fife that waa expected to include 1979. The fteuki for paat-work-Uft benefiu thus
do not substantially alter the conchutona that were drawn from the more accurate data on the tingle year 1979.
Summary The results of this study describe a compensation system that pays only 34 percent of the lanes af the 124 widows who received compensation in 1979. Payments am not distributed equitably although one ofthe causa of this inequity is the failure of widows re claim benefits. Those who succeed in commonlaw suits receive die mom compensation, whereat workers' compensation plana fail
bath the two-thirds undud and the
promise of universa] coverage. Thasc failures are not Umitcd to compen
sating deaths from occupational Qlnew. Chritk condudaes about the survivors of death by workplace injury art timilar to the findings hem. Chrit concluded, for exam ple. that to 37 of II states in 1954. workers' eumpensation replaced 40 percent or less of the awimated lesots caused by occupational death." Our estimates are from 34 to 45 patent for mo* workers' compensation recipients. Chrit alio described the prob lem mentioned earlier of widows who receive no social aecurity benefits between the time their dependents leave home and the time they thernachwa retina.*

ocher toxic subetancea that could be desig nated for coverage at a later date. TV b&l prohibits workers from suing employers or
producers who purchase Insurance in amounts to V sec by the UJ. Secretary of
Labor. Employes and produces can
choose whether or not to purchase their own insurance, subject to the ptovksons of the bill, damn are to V administered by
tV Office of Wbrkcn' Compensation aftV U.S. Depanmcnt of Laban Death benefits are to V paid in a lump sum equal so*the product of M percent of die avenge manufacturing weekly wage for the month fa which the death occurred, or BO percent of the national construction average weekly wage for the month in which the death occurred ... multiplied by HO.""
In order so evaluate the potential ade-
Uting the methods described earlier, we converted the lump sum to an annual income stream, and we uwaed that all the
widows would receive benefits. Thble 4 presents the ratios of benefits to Iosks from the time ofdeath to the expectedend ofthe wofk Kit.
The tumhs shew that H.R. 3175 would mVtantially increase the adequacy of compensation beyond that provided by workers' comperesnon and the common law. They also demonstrate that the paymans ef a lump sum not related to individual tomes aberinunaus against sur vivors with relatively large losses. If H.R. 5175 benefits had scan paid to the 560 survivors studied here, 60.5 percent (the median) of their loams would have been nunbunad. This la a higher percentage of
widows'lomei than are our estimates for the anal number of widows who received payments in 1S79. TV meat important improvement over the current compensa
tion spurn, however; is the payment of benefitsto widowswho would not V paid at all under the current system.
TV Improvement that we estimate from tV Miller bill depends on the awumpeion ef universal coverage. Experience with workers' compensation, on which the bill is minified warm that our asmmpcion may V too optimistic. TV failure of workers'
compensation to pmvide universal coverage colon so the need for natatory provisions

The implicatio&i of thii *udy are more general than our cencluoons regarding
