1
00:00:47.910 --> 00:00:52.410
Every day, many of us put something into
the atmosphere that shouldn't be there.

2
00:00:53.370 --> 00:00:57.750
Fortunately, most of these substances are
harmless in the small quantities released.

3
00:00:58.490 --> 00:01:04.950
But even heavy doses of ordinary household
products could cause health problems if
misused.

4
00:01:06.470 --> 00:01:10.290
We know that cigarette smoking can be
hazardous to a person's health.

5
00:01:10.490 --> 00:01:14.350
And there is strong evidence that if you
combine the inhalation of cigarette smoke

6
00:01:14.350 --> 00:01:16.790
with inhalation of certain other
substances,

7
00:01:16.790 --> 00:01:20.270
you greatly increase the risk of lung
disease.

8
00:01:23.470 --> 00:01:27.110
Asbestos, like thousands of other
materials used every day by industry,

9
00:01:27.330 --> 00:01:29.530
may be released into the air we breathe

10
00:01:29.530 --> 00:01:32.650
and might pose health problems under
certain conditions.

11
00:01:33.590 --> 00:01:35.710
But just as we need wood,

12
00:01:36.590 --> 00:01:39.110
asbestos also is needed for the many
valuable

13
00:01:39.110 --> 00:01:42.090
and life-saving contributions it makes to
our way of life.

14
00:01:44.070 --> 00:01:48.450
While some people may believe that the
health risks outweigh the many benefits,

15
00:01:48.450 --> 00:01:52.890
the asbestos industry is confident of its
ability to work safely with a

16
00:01:52.890 --> 00:01:56.630
potentially hazardous material. That's
what this film is about.

17
00:02:09.260 --> 00:02:10.320
Let's be frank,

18
00:02:10.600 --> 00:02:16.060
the U.S. government lists more than 60,000
toxic or harmful substances in

19
00:02:16.060 --> 00:02:19.660
use today and estimates we could be
exposed to more than a hundred thousand

20
00:02:19.660 --> 00:02:23.940
potentially harmful materials in our
modern world. Some of these exist

21
00:02:23.940 --> 00:02:27.720
naturally in our environment but many more
are produced by man.

22
00:02:30.400 --> 00:02:31.600
Asbestos is one

23
00:02:31.600 --> 00:02:37.680
of those natural potentially harmful
materials under certain conditions
exposure to asbestos

24
00:02:37.680 --> 00:02:43.640
can cause serious health problems but
asbestos need not pose a health risk

25
00:02:43.640 --> 00:02:44.980
if it is handled

26
00:02:44.980 --> 00:02:48.380
with caution and treated as one would
treat any of the thousands of other

27
00:02:48.380 --> 00:02:49.380
potentially harmful

28
00:02:49.320 --> 00:02:53.280
materials it need not present any threat
to health still

29
00:02:57.470 --> 00:02:59.810
asbestos can pose a health hazard

30
00:02:59.810 --> 00:03:04.570
in occupational environments when
precautions are not taken to control
exposures

31
00:03:05.790 --> 00:03:10.930
About 1907, a London physician reported
the first case of what he called a diffuse

32
00:03:10.930 --> 00:03:12.690
pulmonary fibrosis

33
00:03:12.690 --> 00:03:17.970
among a group of factory workers who had a
substantial and prolonged exposure to
asbestos.

34
00:03:19.230 --> 00:03:25.510
Around 1930, other researchers
demonstrated that this disease, called
asbestosis,

35
00:03:26.130 --> 00:03:30.610
posed a significant health threat to
factory workers in the asbestos textile
industry.

36
00:03:30.610 --> 00:03:36.160
By then, asbestos companies already had
begun to support

37
00:03:36.160 --> 00:03:41.080
research into the health effects of
asbestos fiber and had intensified efforts
to

38
00:03:41.080 --> 00:03:42.220
control exposures.

39
00:03:43.900 --> 00:03:49.260
The asbestos industry continues to spend
millions of dollars to define the hazards

40
00:03:49.260 --> 00:03:50.940
and ways to control them.

41
00:03:52.680 --> 00:03:57.440
We know that asbestosis is a non-cancerous
lung condition that can be caused by

42
00:03:57.440 --> 00:04:00.220
excessive and prolonged inhalation of
asbestos fiber.

43
00:04:00.220 --> 00:04:06.080
It is one of a number of respiratory
diseases called a pneumoconiosis, each
caused

44
00:04:06.080 --> 00:04:07.080
by inhaling

45
00:04:06.940 --> 00:04:07.940
irritant particles.

46
00:04:10.660 --> 00:04:16.140
A person with asbestosis may experience
unusual breathlessness after periods of

47
00:04:16.140 --> 00:04:17.140
physical exertion.

48
00:04:19.100 --> 00:04:24.240
Deterioration of lung capacity and
function can be measured by pulmonary
function tests.

49
00:04:24.620 --> 00:04:29.700
Also the physician may be able to detect
crackling chest noises with a stethoscope.

50
00:04:29.700 --> 00:04:35.440
Asbestosis is a generalized thickening of
the

51
00:04:35.440 --> 00:04:37.940
delicate lung tissue, preventing the

52
00:04:37.940 --> 00:04:43.580
lungs from efficiently providing oxygen to
the body. This disease can be detected
through

53
00:04:43.580 --> 00:04:46.880
the regular medical exams provided by
asbestos companies.

54
00:04:48.280 --> 00:04:50.640
Since modern environmental controls

55
00:04:50.640 --> 00:04:56.240
have greatly reduced the amount of
asbestos that workers might be exposed to,
it is very

56
00:04:56.240 --> 00:05:01.080
likely that asbestosis will cease to be a
significant health problem in the

57
00:05:01.080 --> 00:05:06.740
future. It also has been found that
inhalation of

58
00:05:06.740 --> 00:05:08.480
asbestos fibers may result

59
00:05:08.480 --> 00:05:13.740
in an increased risk of developing
bronchogenic or lung cancer.

60
00:05:14.080 --> 00:05:15.200
With very

61
00:05:15.200 --> 00:05:21.080
few exceptions, this increased risk has
been found only in persons

62
00:05:21.080 --> 00:05:22.080
who smoke

63
00:05:21.760 --> 00:05:27.780
cigarettes. Asbestos exposed persons who
do not smoke have no greater chance of

64
00:05:27.780 --> 00:05:33.360
getting this disease than any other person
who does not smoke. The third disease
sometimes

65
00:05:33.360 --> 00:05:39.920
associated with asbestos inhalation is a
very rare cancer called mesothelioma.

66
00:05:40.360 --> 00:05:41.360
It affects

67
00:05:41.240 --> 00:05:47.200
the lining of the chest cavity called the
pleura or the abdominal cavity called the
peritoneum.

68
00:05:48.260 --> 00:05:53.580
Little is known about the biological
factors involved in this disease but
research indicates

69
00:05:53.580 --> 00:05:59.420
that asbestos exposure is not the
exclusive cause mesothelioma

70
00:05:59.420 --> 00:06:00.420
has been

71
00:06:00.260 --> 00:06:05.300
found in persons who have no history of
exposure to asbestos fiber it

72
00:06:05.300 --> 00:06:06.700
should be

73
00:06:06.700 --> 00:06:11.220
noted that all of these asbestos
associated diseases have long latent

74
00:06:11.220 --> 00:06:16.160
periods which is that period of time
between exposure and development of the

75
00:06:16.160 --> 00:06:20.500
disease up to 40 years in some cases
medical

76
00:06:22.160 --> 00:06:23.440
scientists also are

77
00:06:23.440 --> 00:06:27.740
investigating the possibility that
exposure to asbestos might result in an

78
00:06:27.740 --> 00:06:28.920
increased risk of

79
00:06:28.920 --> 00:06:34.360
developing gastrointestinal cancer, a
disease of the digestive tract, although

80
00:06:34.360 --> 00:06:35.360
there is no

81
00:06:35.000 --> 00:06:40.880
conclusive evidence of any risk at this
time. Now all this

82
00:06:40.880 --> 00:06:42.680
talk about disease is not meant to

83
00:06:42.680 --> 00:06:47.400
frighten you but to inform. People who
might be exposed to asbestos should know

84
00:06:47.400 --> 00:06:48.400
what risks they

85
00:06:48.360 --> 00:06:52.100
face if they or their employer fail to
follow safe work procedures.

86
00:06:52.340 --> 00:06:53.760
This is no different than

87
00:06:53.760 --> 00:06:57.300
a person's right to know about any other
material that could cause accidental harm

88
00:06:57.300 --> 00:06:58.300
whether at work

89
00:06:58.100 --> 00:07:03.360
or at home it is important to remember
that while

90
00:07:03.360 --> 00:07:05.960
asbestos may get into the air we breathe

91
00:07:06.620 --> 00:07:11.840
this does not necessarily mean it will get
into our lungs or that if it does that

92
00:07:11.840 --> 00:07:12.840
it will make us

93
00:07:12.480 --> 00:07:18.200
ill to see why this is true let's take a
look at the human respiratory system

94
00:07:18.200 --> 00:07:19.200
and how it works

95
00:07:19.160 --> 00:07:24.940
first the human body has a remarkable
built-in

96
00:07:24.940 --> 00:07:28.120
defensive system for coping with inhaled
dust

97
00:07:28.120 --> 00:07:33.860
and other foreign material including
asbestos fiber all the air we breathe

98
00:07:33.860 --> 00:07:35.340
must first pass

99
00:07:35.340 --> 00:07:40.620
our little nose hairs which pre filter the
larger particles so that only particles

100
00:07:40.620 --> 00:07:41.620
of a certain size

101
00:07:41.480 --> 00:07:47.020
can enter the respiratory tract our
respiratory tract is lined with a sticky

102
00:07:47.020 --> 00:07:48.660
mucus carpet which

103
00:07:48.660 --> 00:07:54.760
moves on top of hair-like cells called
cilia. This escalator system traps and

104
00:07:54.760 --> 00:07:59.940
then sweeps upward unwanted particles and
fibers back up to the nasal

105
00:07:59.940 --> 00:08:04.480
passageways where they can be removed or
swallowed and eventually eliminated from

106
00:08:04.480 --> 00:08:10.660
the body by that route. This mucociliary
escalator system continues all

107
00:08:10.660 --> 00:08:15.960
the way from the nasal passageways down
the trachea or windpipe into the two

108
00:08:15.960 --> 00:08:21.800
main passages to our lungs and on into
smaller and smaller tree-like branches.

109
00:08:22.400 --> 00:08:28.880
At the end of these passageways are tiny
structures called alveoli where oxygen

110
00:08:28.880 --> 00:08:34.600
and carbon dioxide are exchanged.
Particles that manage to escape the

111
00:08:34.600 --> 00:08:38.960
cilial defense system are then subject to
attack by special types of cells

112
00:08:38.960 --> 00:08:43.660
which envelop and render virtually
harmless most invading particles.

113
00:08:47.260 --> 00:08:52.440
One point that cannot be overemphasized is
that smoking greatly increases the risk of

114
00:08:52.440 --> 00:08:56.500
developing lung cancer in persons who are
exposed to asbestos fiber.

115
00:08:57.940 --> 00:09:03.800
One of the reasons for this is that
smoking damages the mucus carpet so it can
no longer

116
00:09:03.800 --> 00:09:05.080
trap invading particles.

117
00:09:05.540 --> 00:09:12.000
Also smoke deposits cause changes in lung
tissue which can render other defensive
systems

118
00:09:12.000 --> 00:09:13.000
ineffective.

119
00:09:12.400 --> 00:09:18.300
So if you are potentially exposed to
asbestos and don't smoke,

120
00:09:18.480 --> 00:09:21.040
don't start. If you do

121
00:09:21.040 --> 00:09:25.240
smoke, make a sincere effort to stop for
your own sake and that of your family.

122
00:09:27.790 --> 00:09:28.810
One of the medical

123
00:09:28.810 --> 00:09:33.290
scientists who has spent a great part of
his life studying the health effects of
asbestos

124
00:09:33.290 --> 00:09:39.330
is Dr. George Wright, an independent
medical consultant who directs the
scientific committee

125
00:09:39.330 --> 00:09:42.990
of the Institute for Occupational and
Environmental Health, Dr.

126
00:09:43.130 --> 00:09:44.130
Wright.

127
00:09:44.550 --> 00:09:48.590
We should remember that the health
problems we are seeing today

128
00:09:49.330 --> 00:09:51.910
are not the result of present working
conditions,

129
00:09:52.230 --> 00:09:55.010
but of conditions that existed decades ago

130
00:09:55.010 --> 00:10:00.010
before any of us were fully aware of the
seriousness of the problem.

131
00:10:00.850 --> 00:10:03.710
The reason for the lag in our knowledge

132
00:10:03.710 --> 00:10:08.950
is that all the diseases in question have
long, latent periods.

133
00:10:09.510 --> 00:10:15.750
They don't develop overnight, and in some
cases, not even after 30 years.

134
00:10:17.310 --> 00:10:21.290
I can't say with certainty that at some
time in the future,

135
00:10:21.430 --> 00:10:25.550
we will never again see another case of
asbestos-related disease.

136
00:10:26.630 --> 00:10:31.210
But certainly we won't be experiencing the
problems we must face today,

137
00:10:31.210 --> 00:10:34.710
which developed as the result of our past
ignorance.

138
00:10:37.490 --> 00:10:38.790
Another recognized

139
00:10:38.790 --> 00:10:42.390
authority in the field of respiratory
disease and asbestos is Dr.

140
00:10:42.510 --> 00:10:43.510
Paul Kotin,

141
00:10:43.430 --> 00:10:47.910
now Senior Vice President for Health,
Safety, and Environment of the Johns-
Manville

142
00:10:47.910 --> 00:10:54.590
Corporation. Dr. Kotin. As we have learned
more about the hazards, we

143
00:10:54.590 --> 00:10:58.870
also have learned more about how to
control them. The industry has made

144
00:10:58.870 --> 00:11:03.070
significant progress in improving dust
control systems and thereby reducing

145
00:11:03.070 --> 00:11:08.590
worker exposure. A number of studies of
work populations has shown that a marked

146
00:11:08.590 --> 00:11:12.970
decrease in asbestos related disease will
occur where efficient dust control

147
00:11:12.970 --> 00:11:17.110
systems have been installed and where
proper work procedures are followed.

148
00:11:17.710 --> 00:11:21.390
Recent studies of persons who have worked
under conditions of strict dust

149
00:11:21.390 --> 00:11:25.510
control indicate that the incidence of
disease has been greatly reduced.

150
00:11:28.290 --> 00:11:29.290
The

151
00:11:28.930 --> 00:11:34.410
government also has acted to protect
asbestos workers. In 1972 the

152
00:11:34.410 --> 00:11:38.930
U.S. Occupational Safety and Health
Administration, called OSHA, set permanent

153
00:11:38.930 --> 00:11:39.930
standards for

154
00:11:39.730 --> 00:11:42.110
occupational exposure to asbestos.

155
00:11:42.830 --> 00:11:47.970
The standards require that airborne levels
of asbestos in the workplace be limited to

156
00:11:47.970 --> 00:11:53.850
a certain number of fibers per cubic
centimeter of air over the average eight-
hour workday.

157
00:11:54.550 --> 00:11:59.510
These exposure limits are sometimes
referred to as threshold limit values.

158
00:11:59.510 --> 00:12:05.350
They refer to airborne concentrations of
substances and represent conditions under

159
00:12:05.350 --> 00:12:06.350
which it is

160
00:12:05.970 --> 00:12:11.530
believed nearly all workers may be
repeatedly exposed day after day without

161
00:12:11.530 --> 00:12:12.550
adverse effect.

162
00:12:14.900 --> 00:12:21.560
The most acceptable way of reducing
exposures is by providing effective
ventilation wherever

163
00:12:21.560 --> 00:12:23.040
dust might be generated.

164
00:12:23.620 --> 00:12:28.840
Exhaust systems at dust sources and in
work areas, enclosure of equipment,

165
00:12:29.100 --> 00:12:30.100
and the use

166
00:12:29.880 --> 00:12:35.380
of water sprays to suppress dust are
common methods used by industry to protect

167
00:12:35.380 --> 00:12:36.380
its workers.

168
00:12:36.340 --> 00:12:39.400
Many of these systems are unique to the
asbestos industry.

169
00:12:39.880 --> 00:12:45.780
The government also requires that certain
other things be

170
00:12:45.780 --> 00:12:47.280
done for companies to remain

171
00:12:47.280 --> 00:12:49.040
in compliance with the standards.

172
00:12:49.440 --> 00:12:54.000
These include monitoring, protective
equipment,

173
00:12:54.340 --> 00:13:00.400
medical surveillance, signs and labels,
and

174
00:13:00.400 --> 00:13:01.460
special protection.

175
00:13:04.480 --> 00:13:07.620
To make sure exposure limits are not
exceeded,

176
00:13:07.940 --> 00:13:11.140
asbestos companies conduct regular
monitoring programs

177
00:13:11.480 --> 00:13:13.600
wherever there is a potential for exposure

178
00:13:13.600 --> 00:13:15.320
above permissible limits.

179
00:13:17.200 --> 00:13:19.720
During these surveys by industrial
hygienists,

180
00:13:19.900 --> 00:13:21.960
the content of the air will be measured

181
00:13:21.960 --> 00:13:23.900
to make certain employees are not

182
00:13:23.900 --> 00:13:27.940
being exposed to airborne levels exceeding
permitted limits.

183
00:13:29.600 --> 00:13:32.480
Monitoring is done on both the personal
and area sampling

184
00:13:32.480 --> 00:13:37.260
basis. Workers may be asked to wear a
small portable pump while working.

185
00:13:37.460 --> 00:13:38.460
This

186
00:13:37.900 --> 00:13:42.160
pump draws in air from the breathing zone
and passes it through a filter.

187
00:13:42.620 --> 00:13:47.640
Later the industrial hygienist will take a
small piece of the filter, examine it

188
00:13:47.640 --> 00:13:51.160
under a microscope, and count all the
fibers of a certain size.

189
00:13:51.500 --> 00:13:52.500
Through a

190
00:13:52.220 --> 00:13:56.640
series of calculations he then can
determine how much asbestos was in the

191
00:13:56.640 --> 00:14:02.620
air. Sometimes area samples are taken
using

192
00:14:02.620 --> 00:14:04.540
the same equipment except that the

193
00:14:04.540 --> 00:14:06.120
monitor stays in one place.

194
00:14:07.320 --> 00:14:11.560
If asbestos levels are found to be above
permissible limits,

195
00:14:11.840 --> 00:14:14.660
immediate action is taken to correct the
situation.

196
00:14:15.500 --> 00:14:17.960
While engineering solutions are being
implemented,

197
00:14:18.280 --> 00:14:21.280
employees may be required to wear
respirators.

198
00:14:22.500 --> 00:14:26.320
Respirators filter harmful dusts and fumes
from the air we breathe.

199
00:14:26.600 --> 00:14:30.020
They may be required in some cleaning and
maintenance operations

200
00:14:30.020 --> 00:14:33.280
or wherever there is the possibility of
equipment failure

201
00:14:33.280 --> 00:14:37.040
that might release high levels of asbestos
fiber medical

202
00:14:43.310 --> 00:14:44.410
surveillance is

203
00:14:44.410 --> 00:14:50.030
an important part of the OSHA compliance
program free medical examinations are

204
00:14:50.030 --> 00:14:55.190
given all workers exposed to asbestos
fiber the physicians report and discuss

205
00:14:55.190 --> 00:14:59.890
results of the medical exams with
employees and when requested can make

206
00:14:59.890 --> 00:15:06.260
exam records available to the employees
own physician asbestos companies also

207
00:15:06.260 --> 00:15:11.400
post special caution signs where there is
a potential for exposure above

208
00:15:11.400 --> 00:15:16.840
permitted limits. Caution labels also are
placed on materials that might, during

209
00:15:16.840 --> 00:15:20.640
handling or use, produce dust levels that
exceed exposure limits.

210
00:15:21.980 --> 00:15:23.060
Finally, wherever

211
00:15:23.060 --> 00:15:28.240
asbestos exposure limits might be
exceeded, protective clothing is provided

212
00:15:28.240 --> 00:15:32.980
along with facilities to change clothes.
It is important that workers take

213
00:15:32.980 --> 00:15:38.580
to prevent taking any asbestos fiber home
on clothing, shoes, or other items

214
00:15:38.580 --> 00:15:41.280
to avoid exposing others to airborne dust.

215
00:15:45.550 --> 00:15:49.470
The industry's concern extends outside its
plants.

216
00:15:50.010 --> 00:15:55.030
Although there is no firm evidence of any
health hazard to the general public from
asbestos,

217
00:15:55.070 --> 00:15:59.870
protective measures have been taken by
both industry and government to be on the

218
00:15:59.870 --> 00:16:00.870
safe side.

219
00:16:02.660 --> 00:16:07.580
The U.S. Environmental Protection Agency
requires that asbestos-using operations

220
00:16:07.580 --> 00:16:13.720
produce no visible emissions when there is
a potential of asbestos containing visible

221
00:16:13.720 --> 00:16:19.360
emissions a fabric bag filter or other
approved form of emission control

222
00:16:19.360 --> 00:16:24.340
must be used this is

223
00:16:24.340 --> 00:16:30.060
the largest fabric bag filter system in
the world located at an asbestos mill in
Canada

224
00:16:30.060 --> 00:16:35.760
it contains more than 80,000 filter bags
connected by about four miles

225
00:16:35.760 --> 00:16:38.760
of piping although the

226
00:16:38.760 --> 00:16:42.060
principle involved is similar to that of a
household vacuum cleaner.

227
00:16:42.360 --> 00:16:47.840
These and other systems on a smaller scale
are engineering feats that have greatly
reduced

228
00:16:47.840 --> 00:16:51.940
dust levels inside and outside of
asbestos-using operations.

229
00:16:53.140 --> 00:16:59.260
Over the years, the asbestos industry has
spent millions of dollars developing new
dust

230
00:16:59.260 --> 00:17:05.040
control systems and equipment, systems to
reduce grinding dust and to draw away

231
00:17:05.040 --> 00:17:06.040
dust-laden

232
00:17:06.000 --> 00:17:08.720
air from other milling and manufacturing
operations.

233
00:17:11.160 --> 00:17:14.300
Today, asbestos companies are working in
other areas

234
00:17:14.300 --> 00:17:17.100
as well to help reduce or eliminate
exposures,

235
00:17:17.100 --> 00:17:19.300
such as new concepts in packaging.

236
00:17:19.780 --> 00:17:23.500
Often, different kinds of bags are
available, some of which

237
00:17:23.500 --> 00:17:26.540
can be dumped unopened into certain types
of manufacturing

238
00:17:26.540 --> 00:17:27.540
operations.

239
00:17:29.540 --> 00:17:32.480
The use of railroad cars with double wide
doors

240
00:17:32.480 --> 00:17:35.300
to ease loading and unloading is another
development.

241
00:17:38.070 --> 00:17:43.590
Asbestos bags are loaded on sturdy
pallets, glue-locked together, and then
held

242
00:17:43.590 --> 00:17:48.070
securely in place by inflatable dunnage to
keep bags from shifting and breaking

243
00:17:48.070 --> 00:17:49.070
during transport.

244
00:17:51.460 --> 00:17:56.420
Product development also has resulted in
virtually dust-free material, such as

245
00:17:56.420 --> 00:17:59.540
compressed fiber blocks and pellets.

246
00:17:59.780 --> 00:18:03.420
The pellets are gaining popularity with
many asbestos users.

247
00:18:03.420 --> 00:18:09.170
The asbestos industry also has developed
employee and

248
00:18:09.170 --> 00:18:14.530
customer health education programs, making
use of written material, posters,

249
00:18:14.870 --> 00:18:17.150
films, and other visual aids.

250
00:18:20.040 --> 00:18:25.680
Those who work with asbestos should follow
one simple rule, avoid creating dust.

251
00:18:26.340 --> 00:18:29.580
If dust is created, take immediate action
to clean it up.

252
00:18:29.780 --> 00:18:36.100
If a bag is broken, reseal it or put it
into a closed container.

253
00:18:39.370 --> 00:18:45.150
If any fiber is spilled or if dust is
accidentally generated, it should be
cleaned

254
00:18:45.150 --> 00:18:49.630
up quickly with a vacuum system or by
wetting the material first before
sweeping.

255
00:18:51.520 --> 00:18:56.020
Never sweep dry asbestos since you will
create airborne dust.

256
00:18:59.090 --> 00:19:04.650
In all stages of handling where dust could
be created, such as bag opening, follow

257
00:19:04.650 --> 00:19:08.710
safe work practices and use dust control
equipment properly.

258
00:19:10.370 --> 00:19:15.790
When a product must be cut, shaped, or
fitted, take care to avoid generating dust

259
00:19:15.790 --> 00:19:16.790
and inhaling

260
00:19:16.670 --> 00:19:17.670
it. If

261
00:19:23.560 --> 00:19:28.300
you are required to use a respirator, use
it properly and make sure it fits snugly.

262
00:19:28.640 --> 00:19:33.700
If you are not sure how to handle material
or perform an operation without exposing
yourself

263
00:19:33.700 --> 00:19:37.040
to airborne fiber, check with someone who
does know.

264
00:19:38.920 --> 00:19:41.540
Remember, asbestos can be safely handled

265
00:19:41.540 --> 00:19:47.440
and used when proper precautions are taken
keep in mind too that the vast majority

266
00:19:47.440 --> 00:19:48.440
of finished

267
00:19:48.100 --> 00:19:53.120
asbestos products pose little or no threat
to health because the fibers have been

268
00:19:53.120 --> 00:19:54.120
locked in

269
00:19:53.660 --> 00:19:58.400
by means of cement as in asbestos cement
pipe plastic

270
00:19:58.400 --> 00:20:04.120
or other binders therefore the fibers

271
00:20:04.120 --> 00:20:07.820
are not easily released into the air
during normal handling and use

272
00:20:09.780 --> 00:20:12.040
asbestos will not

273
00:20:12.040 --> 00:20:16.280
endanger a person's health as long as
proper work procedures are followed and

274
00:20:16.280 --> 00:20:21.720
dust control equipment is used properly
and once you know them these simple

275
00:20:21.720 --> 00:20:26.520
procedures are as easy to follow as good
safe driving practices
