Concern was also expressed over noise exposures and metallic oxides and gaseous air contaminants. The facility fabricated railroad trackwork including switch points, and various types of crossings and frogs. An environmental evaluation and a medical evaluation were conducted. The grinders were not found to be exposed to toxic concentrations of manganese or nuisance dusts at the time of the survey. Welders were not exposed to toxic concentrations of manganese or vanadium (7440622) fumes, ozone (10028156), nitrogen-dioxide (10102440) or iron-oxide (1332372) fumes. The authors conclude that the workers were not exposed to toxic concentrations of these substances under the conditions studied. The authors recommend that environmental control, manganese screening, and a respiratory protection program be used at this facility.

The workroom air concentrations of crystalline free silica are found to exceed the current NIOSH standard of 0.05 milligram per cubic meter. Employees are also found to be transiently exposed to phosphine (7803512) generated in the machining of nodular iron rolls. The possibility of metal fumes and calcium-oxide (1305788) transiently exceeding the current safety limits during tapping operations is suspected because of the episodic and transient symptoms of mucous membrane and skin irritation noted by cranemen and pitmen. Recommendations include use of low silica containing sand, good housekeeping, better exhaust ventilation, regular wetting of foundry sand with water, mechanizing the shake out procedures, use of breathing apparatus, long sleeve shirts and gloves by cranemen, and repairing the seal on the crane cabs.

(Click to show more)A health hazard evaluation of the room air samples for inorganic mercury (7439976) conducted in the Bruce W. Weatherwax Dental Clinic (SIC-8021) in Torrington, Wyoming, shows that the concentrations of mercury during the evaluation are below the NIOSH detection limit of per cubic meter. A health hazard is not judged to exist at the time of evaluation. Recommendations include use of tightly closed capsules during amalgamation, salvaging all amalgam scraps and storing in a closed container with a layer of water over the amalgam; storing of mercury in an unbreakable, tightly sealed container; and, cleaning up of all mercury spills immediately, preferably by vacuuming. Sweeping has to be avoided because it creates dust and breaks the mercury into even smaller particles that can vaporize more quickly.

The survey was prompted by a request from a representative of at least 24 affected employees, regarding exposure to perchloromethyl-mercaptan (75707) and the sudden death of a 35 year old employee. Environmental sampling and medical evaluation failed to produce evidence of excessive incidence of chronic disease which could be associated with any of the substances in use including perchloromethyl-mercaptan. However, subjective evidence of transient irritation associated with perchloromethyl-mercaptan during the first plant visit and with Captan dust, chlorine (7782505), and imide dust during the follow-up visit was found. Recommendations are made for improved ventilation, pre-employment medical examination and use of respirators.

An authorized representative of the Brotherhood of Painters and Allied Trades, AFL-CIO requested the evaluation on behalf of 5 affected employees. Particulate samples were collected. Standard analytical methods were used to analyze total dust, respirable dust, stannous-octoate (301100), and chromic-oxide (1308389). Trimellitic-anhydride (552307) (TMA) samples were analyzed by rapid esterification gas chromatography. Past occupational history and illness were reviewed. Physical examination revealed eye and nasal irritation, shortness of breath, wheezing and cough, gastric distress, headache, and photophobia. Results of sampling indicated that exposure to chromic-oxide and stannous octoate were less than 40% of the OSHA criteria of 1 and 2 milligrams per cubic meter (mg/m3) respectively. Exposure to TMA ranged from 0.1 to 7.5mg/m3, which exceeded the criteria of 0.1mg/m3 suggested by the authors because there are no current NIOSH guidelines or OSHA standards for TMA. Total airborne particulate dusts ranging from 3 to 77mg/m3 exceeded the Threshold Limit Value of 10mg/m3 for total nuisance dusts. The authors conclude that a health hazard exists at this site because workers were exposed to toxic concentrations of particulate matter and TMA. The authors recommend modifications in the ventilation, respiratory program, work hazard education and physical examination programs.
