H317

SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.

Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

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
