Excerpt from ERG Guide 141 [Oxidizers - Toxic]:

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 tank car or highway tank 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, 2024)

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.

· Consider initial downwind evacuation for at least 100 meters (330 feet).

· If tank, rail tank car or highway tank 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.

Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.

Environmental considerations: Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.

Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations. /Beryllium nitrate solution/

Control of environmental exposure Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. /Beryllium nitrate solution/

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 and plant life; and conformance with environmental and public health regulations.

Product: Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. Contaminated packaging: Dispose of as unused product. /Beryllium nitrate solution/

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits 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.

Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. /Beryllium nitrate solution/

If material not on fire and not involved in fire. Keep material out of water sources and sewers.

If material not involved in fire: Keep material out of water sources and sewers. /Beryllium compound, NOS/

Once in the body, beryllium acts as a hapten and interacts with human leucocyte antigen (HLA) DP presenting cells in the lungs, becoming physically associated with a major histocompatability (MHC) class II molecule. This MHC class II-beryllium-peptide complex is recognized by the T lymphocyte receptor, triggering CD4+ T lymphocyte activation and proliferation. The resulting inflammatory response is a cell-mediated process orchestrated by cytokines and results in the formation of (usually pulmonary) granulomas. Beryllium's toxicity may be controlled by the iron-storage protein ferritin, which sequesters beryllium by binding it and preventing it from interacting with other enzymes. Nitrate's toxicity is a result of it's conversion to nitrite once in the body. Nitrite causes the autocatalytic oxidation of oxyhemoglobin to hydrogen peroxide and methemoglobin. This elevation of methemoglobin levels is a condition known as methemoglobinemia, and is characterized by tissue hypoxia, as methemoglobin cannot bind oxygen. (A2450, L1613, L25, A37, A91)

There is sufficient evidence in humans for the carcinogenicity of beryllium and beryllium compounds. Beryllium and beryllium compounds cause cancer of the lung. There is sufficient evidence in experimental animals for the carcinogenicity of beryllium and beryllium compounds. Beryllium and beryllium compounds are carcinogenic to humans (Group 1). /Beryllium and beryllium compounds/

A1; Confirmed human carcinogen. /Beryllium and compounds, as Be/

Beryllium and beryllium compounds are known to be human carcinogens based on sufficient evidence of carcinogenicity from studies in humans. /Beryllium and compounds/

1, carcinogenic to humans. (L135)

Acute inhalation of a high level of beryllium can result in a pneumonia-like condition called acute beryllium disease. Chronic inhalation of beryllium can cause an inflammatory reaction in the respiratory system called chronic beryllium disease. Chronic beryllium disease may result in anorexia and weight loss, as well as right side heart enlargement and heart disease in advanced cases. Chronic exposure can also increase the risk of lung cancer. Skin contact with beryllium results in contact dermatitus. Nitrate and nitrite poisoning causes methemoglobinemia. Nitrites may cause pregnancy complications and developmental effects. They may also be carcinogenic. (L1137, L24, L25)

The substance can be absorbed into the body in hazardous amounts by inhalation of its aerosol, by ingestion and through the skin.

Oral (L1137) ; Inhalation (L1137)

Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed.

Redness. MAY BE ABSORBED!

Redness. Pain.

Nausea. Vomiting. Abdominal pain.

Chronic beryllium disease causes fatigue, weakness, difficulty breathing, and a persistent dry cough. Nitrate and nitrite poisoning causes methemoglobinemia. Symptoms include cyanosis, cardiac dysrhythmias and circulatory failure, and progressive central nervous system (CNS) effects. CNS effects can range from mild dizziness and lethargy to coma and convulsions. (L1137, L24, L25)

Fibrogenic - Inducing tissue injury and fibrosis (scarring).

Chronic beryllium disease is treated with immunosuppressive medicines, usually of the glucocorticoid class. Methemoglobinemia can be treated with supplemental oxygen and methylene blue 1% solution administered intravenously slowly over five minutes followed by IV flush with normal saline. Methylene blue restores the iron in hemoglobin to its normal (reduced) oxygen-carrying state. (L1613, L24)

The efficacy of Tiron and calcium disodium EDTA in the treatment of experimental beryllium intoxication was investigated in rats. Beryllium nitrate was administered intramuscularly (50 mg/ kg) once only, provoking duration-dependent changes. Maximum changes were recorded after a 7-day regimen. Considerable inhibition was recorded in protein and glycogen contents, as well as in the activity of alkaline phosphatase, glucose-6-phosphatase, acid phosphatase and lipid peroxidation. These parameters were restored considerably with chelation therapy, but comparatively Tiron offered better protection. These findings were further confirmed by atomic adsorption spectrophotometry. Tiron was found to be significantly more effective than CaNa(2)EDTA in reducing the beryllium concentration in the liver, kidney and lungs.

The efficacy of Tiron (4,5-dihydroxybenzene 1,3-disulfonic acid disodium salt) was examined in the treatment of beryllium-induced maternal and developmental toxicity in rats. Single administration of beryllium nitrate at a dose of 50 mg/kg (i.m.) on day 13 of gestation caused reductions in fetal and placental weights, the number of implantation sites and number of corpora lutea, as well as causing post-implantation loss, stunted growth, increase in the number of resorptions, and also a disturbed sex ratio. Maternal toxicity was demonstrated by reduction in body weight gain. Administration of beryllium also showed significant alteration in the hematological and biochemical indices of the mother as well as the fetus. Marked decreases were recorded in hemoglobin percentage, blood sugar levels, serum protein contents and serum alkaline phosphatase activity. By contrast, significant elevation was found in the activity of transaminases (aspartate aminotransferase and alanine aminotransferase). Tissue protein contents, glycogen contents, activities of alkaline phosphatase, adenosine triphosphatase and succinic dehydrogenase of kidney, lungs and uterus, and maternal and fetal liver all showed significantly decreased values after beryllium exposure, and remarkable elevation was observed in acid phosphatase, glucose-6-phosphatase and hepatic lipid peroxidation. These parameters were restored considerably with administration of 471 mg/kg i.m. Tiron from days 14 to 18 of gestation. Atomic absorption spectrophotometry also revealed a high concentration of beryllium in different organs of pregnant rats. Interestingly, a small amount of metal ion was also detected in the fetus and reduced accumulation of beryllium was noticed after Tiron treatment.

Influence of adjuvants i.e., alpha-tocopherol (25 mg/kg, p.o.) and piperine (10 mg/kg, p.o.) on therapeutic potential of chelator tiferron (300 mg/kg, i.p.) was evaluated to encounter toxicogenic events of beryllium exposure. Albino rats were exposed to beryllium nitrate (1 mg/kg, i.p.) daily for 28 days followed by treatment of aforesaid therapeutic agents for 5 consecutive days. Results were considered to be significant at p < or =0.01 and p < or =0.05. Exposure to beryllium increased its concentration in liver, kidney and serum causing significant alterations in the activity of CYP-450 2E1 system, microsomal lipid peroxidation and protein; alkaline phosphtase, lactate dehydrogenase, gamma-glutamyl transpeptidase, bilirubin, creatinine and urea in serum; activity of acid phosphatase, alkaline phosphatase, adenosine triphosphatase, glucose-6-phosphatase and succinic dehydrogenase in liver and kidney. Beryllium exposure also induced severe alterations in histopathology and ultramorphology of liver and kidney proving its toxic consequences at cellular level. Tiferron along with adjuvants dramatically reversed alterations of all variables more towards control rather than individual treatment. Study concluded that tiferron in combination with alpha-tocopherol and piperine respectively was beneficial in diluting beryllium induced systemic toxicity; however, combination of tiferron and piperine presented more pronounced therapeutic potential.

The combined effect of gallic acid (3,4,5-trihydroxy benzoic acid; GA; 50 mg/ kg i.p.) and propolis (200 mg/ kg p.o.) was evaluated against beryllium-induced biochemical and morphological alterations in the liver and kidney. Female albino rats were exposed to beryllium nitrate (1 mg/ kg i.p.) daily for 28 days followed by treatment with the above mentioned therapeutic agents either individually or in combination for five consecutive days. Exposure to beryllium increased its concentration in the serum, liver and kidney and caused significant alterations in cytochrome P450 enzymes, microsomal lipid peroxidation and protein contents. Beryllium administration significantly altered the aspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, gamma-grutamy1 transpeptidase, bilirubin, creatinine and urea in serum, and the activity of acid phosphatase, alkaline phosphatase, adenosine triphosphatase, glucose-6-phophatase and succinic dehydrogenase, triglycerides, cholesterol, protein contents, glycogen contents, lipid peroxidation and glutathione level in the liver and kidney. Beryllium exposure induced severe alterations in hepatorenal morphology, revealing its toxic consequences at a cellular level. Individual administration of GA and propolis reduced the effects on the studied parameters to a degree. Interestingly, GA in conjunction with propolis reversed the alterations in all of the variables examined, highlighting the beneficial effects of combined therapy over monotherapy in the alleviation of beryllium-induced systemic toxicity.

/LABORATORY ANIMALS: Acute Exposure/ Toxic effects of beryllium nitrate on the level of total and esterified cholesterol have been observed on liver, kidney, lungs, spleen, heart, thigh muscles, brain adrenal and the reproductive organs of adult female albino rats. A dose of 50 mg/kg body wt of beryllium nitrate was prepared and injected intramuscularly once only in experimental rats. The rats were sacrificed after 2, 10 and 30 days of treatment and total and esterified cholesterol level were estimated in different tissues. Total cholesterol level were elevated in all the organs after 2, 10 and 30 days of treatment with peak values occurring at 30 days. Corresponding increases were also observed in esterified cholesterol levels in the treated rats at specified time intervals.

/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ Animals were exposed to beryllium nitrate (0.5 mg/kg, orally, daily 5 days/week) for 21 days. Twenty-four hours after the last dose they were injected with a chelating agent (25 or 50 mg/kg, twice daily for 5 days). The administration of meso-2,3-dimercaptosuccinic acid and 2,3-dimercaptopropane 1-sulfonate at a dose of 50 mg/kg marginally elevated the fecal excretion of beryllium. 2,3-Dimercaptopropane 1-sulfonate was effective in depleting beryllium from the liver, spleen and kidneys. However, 2,3-dimercaptopropane 1-sulfonate (50 mg/kg) results in the redistribution of beryllium to blood. Beryllium-induced inhibition of hepatic alkaline phosphatase and hepatic adenosine triphosphatase (ATPase) were restored considerably with the chelating agents. Also, hepatic and renal histopathological lesions were less marked in rats treated with 2,3-dimercaptopropane 1-sulfonate (50 mg/kg) compared with those treated with beryllium per se and meso-2,3-dimercaptosuccinic acid. These effects were more prominent at the 50 mg/kg dose of chelating agents than at 25 mg/kg. These result, suggest that treatment with 2,3-dimercaptopropane 1-sulfonate has some beneficial effects in experimental beryllium intoxication.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 and plant life; and conformance with environmental and public health regulations.

Product: Burn in a chemical incinerator equipped with an afterburner and scrubber but exert extra care in igniting as this material is highly flammable. Offer surplus and non-recyclable solutions to a licensed disposal company. Contact a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. Contaminated packaging: Dispose of as unused product. /Beryllium nitrate solution/

/GUIDE 141: OXIDIZERS - TOXIC/ Fire or Explosion: These substances will accelerate burning when involved in a fire. May explode from heat or contamination. Some may burn rapidly. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

/GUIDE 141: OXIDIZERS - TOXIC/ Health: Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.

/GUIDE 141: OXIDIZERS - TOXIC/ Public Safety: CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. 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. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering.

/GUIDE 141: OXIDIZERS - TOXIC/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing will only provide limited protection.
