Safety and Health, Cincinnati, OH. |
An occupational
health prevalence study of chronic respiratory disease in 457
male aluminum potroom workers is undertaken. The tests consist
of an interviewer administered questionnaire, forced spirometry,
closing volume determination, chest x-ray, sputum cytology,
serum alpha-1 antitrypsin, serum trypsin inhibitory capacity,
blood pressure, and urine and serum fluoride.
The prevalence of respiratory disease is 4.9% in the aluminum
workers and 5.3% in the controls. The prevalence ratios are
examined for workers using different processes, for potroom
exposure history, and current employment status. No significant
differences are observed. The aluminum workers have more abnormalities
in closing volume measurements and more mild atypia of the sputum.

An industrial
hygiene survey was conducted at the Agrico Chemical Company,
Pierce, Florida, June 22-26, 1975 to collect environmental data
on exposure of personnel to sulfuric acid, phosphoric acid,
chromium, uranium, fluorides, and
radiation during the cleaning of the phosphoric acid reactor
vessels. The process of phosphate fertilizer manufacturing is
described, and information is given on the medical, safety and
industrial hygiene program at this facility. Concentrations
of fluoride, phosphoric acid, cadmium dust, chromium, canadium
dust, and sulfuric acid were all below the legal standards.
Recommendations are made for improving the safety of
the tank cleaning procedure. Agrico's facility is not suitable
for epidemiological study because the latency period is too
short and also the medical and personnel records were not adequate
to perform a retrospective mortality study. Data on uranium
and radiation exposure will be included in a separate report. |

America (SIC-3334) facilities in Tennessee on August 29, 1972.
The company employed approximately 6,000 workers. The survey
indicated a potential for exposure to coal tar pitch (65996932),
carbon dust (7440440), fluorides,
carbon-monoxide (630080), noise and heat. These exposures were
most severe in the south building of the facility where alumina
was reduced to aluminum in both prebaked and Soderberg cells
and at auxiliary operations where carbon anodes and cathodes
were produced. The authors recommend additional investigation,
including analysis of approximately 75 air samples. Prepared

Exposure
to hydrogen-fluoride (7664393) is reviewed. Volcanoes are the
only natural source of hydrogen-fluoride but it is often released
as an industrial effluent. Pathological
effects noted in animals begin with irritation of mucous membranes
and localized respiratory tissue damage, progressing with continued
exposure to death from respiratory distress and cardiac arrest.
The mean lethal concentrations are given for several
species. Industrial accidents have provided information about
human toxicity of the gas and its liquid phase. Plants
are even more readily damaged by hydrogen-fluoride than are
animals. Atmospheric concentrations of hydrogen-fluoride are
most likely to reach hazardous limits down wind of industrial
effluent stacks. Recommendations for the short term public
limit of hydrogen-fluoride are for concentrations not to exceed
5 milligrams per cubic meter (mg/m3) of air for up to 60 minutes
of exposure or a 5 hour a day, a 3 or 4 day a month limit of
1mg/m3 or an equivalent of 1 part per million (ppm). The recommended
public emergency limit, which allows for temporary discomfort
but no residual damage, is 10 ppm for 10 minutes or 5 ppm for
30 or 60 minutes. |

The
Paducah Plant is a government-owned gaseous diffusion plant
operated by Union Carbide Corporation, Nuclear Division, for
the Atomic Energy Commission. In addition to the uranium hexafluoride
in the isotope separation cascade, large
quantities of uranium fluorides and oxides are processed in
the feed manufacturing plant and in the uranium metal foundry.
Significant quantities of hexavalent chromium are used each
day as a corrosion inhibitor in the recirculating water of the
plant cooling system. Therefore, uranium,
fluorides, and hexavalent chromium are of primary interest in
the environmental monitoring program of the Paducah Plant. Other
factors routinely checked are pH, beta activity, and background
gamma radiation. Air and water are sampled continuously in the
vicinity of the plant, and grab samples of Ohio River water
and vegetation samples are collected monthly. |

This document
describes research conducted from July 1960 to July 1961 on
the use of radioisotopes and labeled hormones in endocrine and
metabolic studies. By measuring levels of C sup 14 -labeled
proline in the femurs of rats, the author demonstrated that
removal of the parathyroid glands slowed removal of calcium
in bones. Preliminary studies demonstrated
an inverse relationship between the level of fluorine in drinking
water and the number of bone cells in the femurs of rats. The
effects of x-radiation on the thyroid gland and on adjacent
tissues were determined by measuring the levels of sup 131 I
in the thyroid following exposure. Enzymatically controlled
processes were distinguished from physicochemical controlled
process by studying the effect of sup 131 I on the thyroid glands
of frogs. Attempts to transplant parathyroid tissue onto the
surface of bone were not definitive and will have to be modified.

The safety measures used when handling
beryllium and its compounds, especially the soluble ones (fluorides,
oxyfluorides, chlorides, sulfides, acetates, etc.), are
determined by their toxicity. Although the soluble compounds
of beryllium are more toxic to man, one must not underestimate
the danger presented by beryllium and its insoluble compounds
after penetrating into the respiratory organs in the form of
finely dispersed aerosols. The maximum permissible concentration
of beryllium and its compounds has been set in the USSR at 0.001

Because
the current literature contains reports that throw doubt on
the toxicity of beryllium per Se and point
instead to the putative toxicity of the acidic ions of its salts,
especially sulfate and fluoride, an inhalation study
of sodium acid sulfate mist was performed to determine whether
the sulfate ion had a toxicity comparable to that of beryllium
sulfate. Accordingly, an inhalation experiment was performed
in which the conditions of exposure duplicated those in which
beryllium sulfate had been used as the toxic agent except that
in the present study, sodium acid sulfate solution, with a pit
of 1.7, had been substituted for the beryllium salt solution.
Twenty guinea pigs and 10 rats were exposed daily for more than
2 weeks to 75 mg/m3 of the acid sulfate salt. This treatment
produced no general weight loss in either species. In one rat
and 2 guinea pigs that died from causes apparently unrelated
to the exposure, however, some weight loss occurred. No lesions
were observed in any animal tha [abstract truncated] |

This
report addresses toxicity (largely chemical) of Manhattan
Project materials from the point of worker protection. Known
chemical toxicities of X material (uranium), nitrous fumes,
fluorine, vanadium, magnesium, and lime are described
followed by safe exposure levels, symptoms of exposure, and
treatment recommendations. The report closes with an overview
of general policy in a question and answer format.
