Bleidiiodid

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:；SMALL FIRE: Dry chemical, CO2 or water spray.；LARGE FIRE: Water spray, fog or regular foam. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal. Avoid aiming straight or solid streams directly onto the product.；FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)

Remove at once all cases of lead intoxication from further exposure until the blood level is reduced to a safe value; immediately place the individual under medical care.；INGESTION: give gastric lavage using 1% solution of sodium or magnesium sulfate; leave 15-30 mg magnesium sulfate in 6-8 oz. of water in the stomach as antidote and cathartic; egg white, milk, and tannin are useful demulcents; atropine sulfate and other antispasmodics may relieve abdominal pain, but morphine may be necessary.；EYES or SKIN: flush with water. (USCG, 1999)

Use dry chemical, carbon dioxide, water spray, or foam extinguishers ... If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position.

If material on fire or involved in fire: Extingiush fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)

Lead iodide must be stored to avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and chemically active metals (such as potassium, sodium, magnesium, and zinc) since violent reactions occur. A regulated, marked area should be established where this chemical is handled, use or stored ...

Protect from light.

Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.

Environmental considerations: Land spill: Dig a pit, pond, or 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 consideratons: Water spill: neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). If dissolved, in region of 10 ppm or greater concn, apply activated carbon 10 times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants & precipitates.

Excerpt from ERG Guide 151 [Substances - Toxic (Non-Combustible)]:；Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Cover with plastic sheet to prevent spreading. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. For solids, prevent dust cloud and avoid inhalation of dust. (ERG, 2024)

If material not on fire and not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary.

Personnel protection: Keep upwind. Wear appropriate chemical protective gloves, boots, and goggles. Avoid breathing vapors. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

SRP: Contaminated protective clothing should be segregated in a manner so that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

The blood Pb of these children should be closely monitored and appropriate steps should be taken to minimize the child's exposure to environmental lead.] /Lead/

Lead is a neurotoxin and has been known to cause brain damage and reduced cognitive capacity, especially in children. Lead exposure can result in nephropathy, as well as blood disorders such as high blood pressure and anemia. Lead also exhibits reproductive toxicity and can results in miscarriages and reduced sperm production. (L21)

Reproductive toxicity includes developmental effects. See Guidelines for Reproductive Toxicity Risk Assessment.；IARC Carcinogen - Class 2: International Agency for Research on Cancer classifies chemicals as probable (2a), or possible (2b) human carcinogens.；NTP Carcinogen - Reasonably anticipated to be a human carcinogen.；ACGIH Carcinogen - Confirmed Animal.

Lead mimics other biologically important metals, such as zinc, calcium, and iron, competing as cofactors for many of their respective enzymatic reactions. For example, lead has been shown to competitively inhibit calcium's binding of calmodulin, interferring with neurotransmitter release. It exhibits similar competitive inhibition at the NMDA receptor and protein kinase C, which impairs brain microvascular formation and function, as well as alters the blood-brain barrier. Lead also affects the nervous system by impairing regulation of dopamine synthesis and blocking evoked release of acetylcholine. However, it's main mechanism of action occurs by inhibiting delta-aminolevulinic acid dehydratase, an enzyme vital in the biosynthesis of heme, which is a necesssary cofactor of hemoglobin. (T4, A20, A22, L136)

/BIRDS and MAMMALS/ ... Female mallards /were dosed/ with 100 mg lead/kg diet. This was added as a mixture of 43 mg/kg lead carbonate, 37 mg/kg lead oxide, and 49 mg/kg lead sulfate, each salt contributing one-third of the total lead. No significant effect on eggshell thickness was found when it was measured on days 76 and 85 of treatment. When lead was added to the diet along with DDE at 40 mg/kg, lead did not increase the effect of the organochlorine on shell thickness.

Symptions of chronic lead poisoning include reduced cognitive abilities, nausea, abdominal pain, irritability, insomnia, metal taste in the mouth, excess lethargy or hyperactivity, chest pain, headache and, in extreme cases, seizures, comas, and death. There are also associated gastrointestinal problems, such as constipation, diarrhea, vomiting, poor appetite, weight loss, which are common in acute poisoning. (A2, L21)

/SIGNS AND SYMPTOMS/ Can cause headache, irritability, reduced memory, and disturbed sleep. Lead poisoning can cause poor appetite, colic, upset stomach, headaches, irritabiity, muscle or joint pains and weakness ... Permanent kidney damage can result from long-term or high exposures. Repeated exposure may cause brain damage and damage to the blood cells, leading to anemia. Higher levels can cause muscle and joint pains, weakness, and fatigue. May cause nerve damage. Lead exposure increases the risk of high blood pressure. Lead Iodide should be handled as a teratogen, with extreme caution. Repeated exposure may cause lead poisoning and/or iodism. Symptoms of iodism can include running nose, headache, mucous membrane irritation, and skin rash.
