A survey of fibre glass exposures and associated skin and
conjunctival irritation among computer technicians in a computer
laboratory, where glass fibre-insulated ceiling pipes were being
repaired, showed that relatively low fibre glass concentration can
cause transient skin and mucous membrane symptoms. The study
concluded that the ACGIH TLVs for fibrous glass may not be
appropriate for assessing fibre glass exposures. |
| 1994 |
192735 |
The authors found considerable evidence of collinearity
between duration of exposure to fibres and to formaldehyde and the
phenolics etc... It indicated that the effects related to
durations of exposure to formaldehyde and the phenolics could not
be distinguished statistically. |
| 1994 |
192267 |
The Danish records of 32 work sites with 340 insulation
workers showed obstructive reduction of lung function is more
pronounced among insulation workers than controls, and that the
effect of smoking is negligible. |
| 1991 |
174239 |
Dr. P. E. Enterline reviewed MMMF on its carcinogenic effects
and concluded that exposure to MMMF should be regulated in the
same manner as exposure to asbestos. |
| 1990 |
164526 |
A US cohort study of 16,661 MMMF workers showed the excess was
greatest for mineral wool workers for respiratory cancer. |
| 1987 |
141335 |
In a follow-up study of an earlier cohort of 2557 workers at an
insulation glass wool facility in Sarnia, Dr. Shannon found a
significant excess of lung cancers among workers stationed inside
facilities. |
| 1985 |
114580 |
Dr. Saracci, the current director of analytical branch of IARC,
reviewed the effects synthetic mineral fibres effect on health in
1985. He found that lung cancer rates are elevated among mineral
fibre workers at 20-30 years from first employment. |
| 1984 |
104733 |
A cohort study of 25,146 MMMF workers in the European
industry showed an excess of mortality due to accidents,
poisoning, and violence. An excess of mortality due to cancer of
the larynx and benign neoplasms was found. The SMR due to lung
cancer was 192, suggesting that there is an increased risk of lung
cancer. |
| 1983 |
103167 |
This study confirmed that asbestos and glass fibres
cytotoxicity was dependent on fibre length for all fibre types. |
| 1983 |
163414 |
This cohort study showed a significant excess in
nonmalignant respiratory disease deaths for fibrous glass workers. |
| 1982 |
105895 |
Dr Saracci reviewed studies on health hazards from exposure to
MMMF. He found a correlation between non-malignant respiratory
diseases, lung cancer and MMMF employment 20 years after first
exposure. |
| 1981 |
115143 |
This toxicity study confirms that microfibres show in-vitro
cytotoxicity to pulmonary alveolar macrophages, similar to
asbestos. Glass fibres can cause acute and chronic lung injury. |
| 1976 |
149850 |
A study of 1,448 fibre glass workers demonstrates a
significant excess of respiratory diseases which is consistent
with an earlier report of an increased risk of chronic bronchitis
as a cause of retirement disability among fibrous glass production
workers. |
| 1975 |
69115 |
A NIOSH walkthrough survey of worker exposure to glass fibres in
a California plant found a glass fibre health hazard existed.
Personal air samples showed that concentrations ranged from 2.1 to
24.4 f/ml. |
| 1974 |
145524 |
A NIOSH exposure measurement showed a highest total dust
concentration at 14.5 mg/m3 and a highest fibre glass
concentration at 44.1 f/ml. |
| 1973 |
155405 |
Worker exposure at a glass fibres plant in Ohio measured
by NIOSH reached as high as 33.6 f/ml in personal total fibre.
Personal respirable fibre concentrations were as high as 22.8
f/ml. |
| 1973 |
97446 |
A survey of fibre glass workers showed respirable fibres up to
5.5 f/ml and total dust up to 12.7 mg/m3. |
| 1973 |
152398 |
An industrial hygiene survey at an insulation plant showed
significant exposure to respirable glass fibres and use of some
asbestos-containing material. |
| 1973 |
67270 |
An exposure investigation at a Kansas fibreglass company found
silica samples exceeded the OSHA standard of 10 mg/m3. Noise
measurements went up to 105 dBA. |
| 1973 |
152508 |
A comprehensive industrial hygiene survey conducted at a fibre
glass company in South Carolina showed exposure to styrene monomer
and silica dust in various operations generally exceeded the OSHA
standards. Poor ventilation caused high levels in the air.
Exposure to noise also exceeded OSHA standards. |
| 1972 |
72131 |
Worker exposure to free silica in the batch and furnace areas at
a fibrous glass company in California exceeded standards. |
