Explosive

An oxidizing agent. Liberates explosive chlorine dioxide gas in the presence of strong acid. Heating a moist mixture with a dibasic organic acid liberates chlorine dioxide and carbon dioxide. Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination with finely divided aluminum can explode by heat, percussion, or friction [Mellor 2:310 1946-47].

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. 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 soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.|If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.

Excerpt from ERG Guide 140 [Oxidizers]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 140 [Oxidizers]: Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers. SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area. SMALL LIQUID SPILL: Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Following product recovery, flush area with water. (ERG, 2016)

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|Avoid skin contact with calcium chlorate. Wear protective gloves and clothing.

NIOSH (NOES Survey 1981-1983) has statistically estimated that 19,597 workers (3,633 of these were female) were potentially exposed to xxx in the US(1). The NOES Survey did not include farm workers.

Inhalation of dust causes irritation of upper respiratory system. Dust irritates eyes and skin. Ingestion causes abdominal pain, nausea, vomiting, diarrhea, pallor, shortness of breath, unconsciousness. (USCG, 1999)

INHALATION: remove to fresh air. EYES: flush with water for 15 min. SKIN: flush with water. INGESTION: induce vomiting and get medical attention. (USCG, 1999)

Emergency and supportive treatment: Maintain on open airway and assist ventilation if necessary. Treat coma, hemolysis, hyperkalemia, and renal or hepatic failure if they occur. Massive hemolysis may require blood transfusions. To prevent renal failure resulting from deposition of free hemoglobin in the kidney tubules, administer intravenous fluids and sodium bicarbonate. /Chlorates/|Specific drugs and antidotes: Treat methemoglobinemia with methylene blue, ... . Methylene blue is reportedly most effective when used early in mild cases but has poor effectiveness in severe cases in which hemolysis has already occurred. Intravenous sodium thiosulfate may inactivate the chlorate ion and has been reported to be successful in anecdotal reports. However, this treatment has not been clinically tested. Administration as a lavage fluid may potentially produce some hydrogen sulfide, and so it is contraindicated. /Chlorates/|Emergency and supportive measures: Maintain on open airway and assist ventilation if necessary. treat fluid losses from gastroenteritis with intravenous crystalloids.

/SIGNS AND SYMPTOMS/ Ingestion causes abdominal pain, nausea, vomiting, diarrhea, pallor, shortness of breath, unconsciousness.|/SIGNS AND SYMPTOMS/ Poisoning is characterized by gastritis (nausea, vomiting, and pain), anoxia, (cyanosis, collapse, and terminal convulsions) secondary to methemoglobinemia, possible liver injury, and nephritis (lumbar pain and oliguria). Nephritis presumably is the direct result of chlorate ion as well as secondary to the destruction of corpuscles. The blood pressure tends to fall and the heartbeat becomes irregular. The liver and spleen may be enlarged and tender. The urine, if any, is brown or black in color and contains casts, red cells, free hemoglobin, and methemoglobin. The blood is brownish in color, and the plasma contains free hemoglobin and free methemoglobin. The red cell count is very low and the white cell count high. Onset may be delayed as much as 12 hr.
