Liquid material spills can be copiously flushed with water and channeled to a treatment system or holding tank for reclamation or proper disposal. Spills of dry material can be removed by vacuuming or wet mopping. Some spills can be removed by hosing, first with a mist of water to dampen the spilled material and then with a more forceful stream that flushes it into a holding tank or other facility for handling contaminated water. Work surfaces or contaminated clothing should never be cleaned by dry sweeping or blowing with pressurized hoses. Recovery systems used to reclaim waste metals should comply with federal, state, and local regulations. All waste materials generated in the handling of cobalt-containing substances should be disposed of in compliance with federal, state, and local regulations. /Cobalt and cobalt salts/

Employers should institute programs that emphasize good personal hygiene to prevent skin and respiratory irritation caused by cobalt containing dusts. After working with cobalt products, workers should thoroughly wash their hands and face before drinking, eating, or smoking. If skin contact with cobalt solutions occurs, the worker should wash the affected skin promptly. The employer should provide showers if workers have substantial contact with cobalt. These workers should be encouraged to wash or shower after each workshift. Employers should prohibit smoking or carrying of tobacco products, and should prohibit eating, food handling, or food storage within the work area. /Cobalt and cobalt salts/|General plant maintenance must be conducted regularly to prevent cobalt containing dusts from accumulating in work areas. Cleaning should be performed with vacuum pickup or wet mopping to minimize the amount of dust dispersed into the air. A decontamination room should be available for cleaning equipment that is to receive major overhaul or maintenance. Spills of cobalt-containing material should be promptly cleaned up to minimize inhalation or dermal contact. /Cobalt and cobalt salts/|Special precautions are necessary when workers must enter tanks or vessels, such as reaction vessels containing cobalt catalysts or vessels used to prepare cobalt salts. Before any worker enters a vessel, all sources for transferring cobalt and other materials into or out of the vessel must be blanked to prevent their entry. The vessel interior must then be washed with water and purged with air. After purging the vessel's atmosphere with suitable instruments to ensure that no hazards from fire, explosion, oxygen deficiency, or dust inhalation exist. No one should enter a tank or vessel without first being equipped with an appropriate respirator and a secured lifeline or harness. Mechanical ventilation should be provided continuously when workers are inside the tank. At least one other worker similarly equipped with respiratory protection, lifeline, and harness should watch at all times from outside the vessel. Workers inside the tank must be able to communicate with those persons outside. Other workers must be available to assist in an emergency. Flame- or spark-generating operations, such as welding or cutting, should be performed only when an authorized representative of the employer has signed a permit based on a finding that all necessary safety precautions have been taken. /Cobalt and cobalt salts/

IDENTIFICATION AND USE: Fluomine, a solid, is a cobalt chelate compound which complexes molecular oxygen and releases it on heating. This property has led to its use as an oxygen source in high-altitude aircraft. HUMAN EXPOSURE AND TOXICITY: There are no data available. ANIMAL STUDIES: Fluomine was highly irritating when instilled in the eyes of rabbits and to the lungs of rats on inhalation. Exposure of rabbit skin to the compound demonstrated moderate irritancy particularly in areas of abrasion. Positive reactions to intradermal challenge were demonstrated after intradermal and inhalation sensitization of guinea pigs. After initial 2-week exposures to determine non-irritating concentrations of dust, rats, mice, guinea pigs and dogs were exposed 6 hr a day for 5 days per week for 6 months to 0.1 and 0.5 mg/cu m concentrations of fluomine dust. A statistically significant decrease in mean body weights of the test rats was observed when compared to the control group. The dust also had irritative effects on the respiratory systems of rats and dogs at the highest exposure level.
