Section 4. First-Aid Measures

Fresh air, rest. Half-upright position. Refer for medical attention.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Refer for medical attention .

General First Aid:

· Call 911 or emergency medical service.

· Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination.

· Move victim to fresh air if it can be done safely.

· Administer oxygen if breathing is difficult.

· If victim is not breathing:

-- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance.

-- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped with a one-way valve or other device).

-- If no pulse detected or no respiratory medical device available, provide continuous compressions. Conduct a pulse check every two minutes or monitor for any signs of spontaneous respirations.

· Remove and isolate contaminated clothing and shoes.

· For minor skin contact, avoid spreading material on unaffected skin.

· In case of contact with substance, remove immediately by flushing skin or eyes with running water for at least 20 minutes.

· For severe burns, immediate medical attention is required.

· Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed.

· Keep victim calm and warm.

· Keep victim under observation.

· For further assistance, contact your local Poison Control Center.

· Note: Basic Life Support (BLS) and Advanced Life Support (ALS) should be done by trained professionals.

Specific First Aid:

· Removal of solidified molten material from skin requires medical assistance.

In Canada, an Emergency Response Assistance Plan (ERAP) may be required for this product. Please consult the shipping paper and/or the "ERAP" section.

Section 5. Fire-Fighting Measures

Use water spray, foam, powder, dry sand. In case of fire: keep drums, etc., cool by spraying with water.

Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Use fine spray or fog to control fire by preventing its spread and absorbing some of its heat. Water or foam may cause frothing of molten sulfur.

If material /is/ on fire or involved in /a/ fire, use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

In Case of Fire: Use appropriate extinguishing media for combustibles in the area. Wear full protective clothing and self-contained breathing apparatus. Evacuate nonessential personnel from the area to prevent human exposure to fire, smoke, fumes or products of combustion. Prevent use of contaminated buildings, area, and equipment until decontaminated. Water runoff can cause environmental damage. If water is used to fight fire, dike and collect runoff.

Burns with a pale blue flame that may be difficult to see in daylight.

Section 6. Accidental Release Measures

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Keep unauthorized personnel away.

· Stay upwind, uphill and/or upstream.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

· Do not touch or walk through spilled material.

Small Dry Spill

· With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

Large Spill

· Wet down with water and dike for later disposal.

· Prevent entry into waterways, sewers, basements or confined areas.

Immediate precautionary measure

· Isolate spill or leak area for at least 25 meters (75 feet) in all directions.

· 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: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

Environmental considerations: Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses.

Enviromental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete.

Large spillages should be dammed-off and pumped into containers; soak up remainder with absorbent material and dispose of in accordance with local regulations.

Stop or reduce discharge of material if this can be done without risk. Eliminate all sources of ignition. Avoid skin contact or inhalation. When spilled in a molten form, contain if possible by forming mechanical or chemical barriers and let it solidify. Shovel solid sulfur into containers with covers (avoid dusting) for recovery or disposal. When spilled in a molten form, contain if possible by using natural deep water pockets, and sand bag barriers to trap material at the bottom. Remove trapped material with suction hoses. If removal is not possible, let it solidify and apply a cover material, preferably inert and basic (limestone), to the spilled area until recovery procedures begin. This will reduce the possible release of sulfuric acid in the water.

Do not contaminate water by cleaning of equipment and when disposing of equipment washwaters.

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.

Completely empty bag into application equipment. Then dispose of empty bag in a sanitary landfill or by incineration, or if allowed by state and local authorities, by burning. If burned, stay out of smoke.

Dump into a landfill site. Recommendable method: Landfill. Not recommendable method: Thermal destruction. Peer review: Caution: sulfur could be a fire hazard and may cause bacterial degradation, landfill is recommendable for small amt only. (Peer-review conclusions of an IRPTC expert consultation (May 1985))

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.

Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR Part 170.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.

For terrestrial uses, do not apply directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not apply when weather conditions favor drift from treated areas.

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Sulfur and related compounds/

Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Administer activated charcoal ... . Cover skin burns with dry sterile dressings after decontamination ... . /Sulfur and related compounds/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasms ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Sulfur and related compounds/

Employment examination should ensure that persons suffering from bronchitis or asthma /are protected against exposure/ to sulfur. In the periodical examination, clinical examination should be supplemented by chest X-ray.

/HUMAN EXPOSURE STUDIES/ A study of the elemental composition of metal working fluid (MWF) aerosols was conducted to determine which component of the MWFs could be responsible for pulmonary function decrements in exposed automobile parts manufacturing workers. Four components were selected for analysis: elemental sulfur, chlorine, chromium and nickel. The concn of these elements in aerosols of the MWFs used by the workers were determined. Associations between the element concn and the overshift FEV1 decrements were examined by case control techniques. The mean chlorine, chromium, nickel and sulfur concn in the straight MWF aerosols were 1.90, 0.16, 0.03 and 4.21 ug/cu m respectively. The mean concn of these elements in the water soluble MWF aerosols were 3.13, 0.15, 0.02 and 3.52 ug/cu m, respectively. Exposure to sulfur concn in the straight and soluble MWF combined was significantly associated with incr of sustaining a 5% or greater overshift decr in FEV1, odds ratio (OR) 3.3. This association was also seen when the sulfur concn of the straight and soluble MWFs was considered separately, ORs 5 and 2.9 respectively. ... A more detailed analysis of the association between sulfur and overshift FEV1 decr showed that the relative risk (RR) for sustaining a 5% overshift decr in FEV1 incr by 2.5 for every unit logarithmic incr in sulfur concn. On a linear scale, this indicated that the RR was 2.7 for sulfur concn above 5.6 ug/cu m compared to concn below 2.1 ug/cu m. ... /Metal working fluid/

/SIGNS AND SYMPTOMS/ When administered orally, sulfur reportedly has a laxative or cathartic effect.

/SIGNS AND SYMPTOMS/ Topically applied sulfur is a keratolytic agent. Sulfur has keratoplastic activity at low concentrations, correcting abnormal keratinization, and keratolytic activity at high concentrations, causing peeling of skin; these effects apparently result from the same action of the drug. ... Although the mechanism of sulfur's keratolytic action has not been determined, this action may depend on formation of hydrogen sulfide when the drug comes in contact with skin; the production of the characteristic odor of rotten eggs when sulfur comes in contact with skin results from hydrogen sulfide formation. Hydrogen sulfide may be formed within the epidermis by sulfur reacting with cysteine.

/SIGNS AND SYMPTOMS/ Acute effects of sulfur inhalation including catarrhal inflammation of nasal mucosa, which may lead to hyperplasia with abundant nasal secretion. Tracheobronchitis is frequent occurrence with dyspnea, persistent cough and expectoration ... sometimes streaked with blood. There may also be irritation of eyes, with lacrimation, photophobia, conjunctivitis and blepharoconjunctivitis; cases of damage to crystalline lens have also been described, with formation of opacities and even cataract and focal chorioretinitis. Skin may be subject to erythematous and eczematous lesions and signs of ulceration, especially in ... workers whose hands are in prolonged or repeated contact with powdered sulfur ... at beginning, miner suffers from upper respiratory tract catarrh, with cough, and expectoration which is mucoid and may even contain grains of sulfur. Asthma is frequent complication. Maxillary and frontal sinuses may be affected; involvement is usually bilateral and pansinusitis may be observed in some cases. ... Lung function exam has shown changes in pulmonary ventilation, increased oxygen consumption, reduced expiratory volume/sec and increased residual volume pulmonary carbon dioxide diffusion capacity was also impaired.

/LABORATORY ANIMALS: Acute Exposure/ Using a maximization test with the guinea pig, a 1% or 5% aqueous solution of elemental or lime sulfur was a moderately strong allergen.

/LABORATORY ANIMALS: Acute Exposure/ In /a/ nonstandard test, using subcutaneous injection in the Wistar rat, a 25% aqueous solution of wettable powder or a 22% solution of lime sulfur caused a four or five (mild or slight irritation or slight erythema).

/LABORATORY ANIMALS: Acute Exposure/ Using the Buehler test, induction doses were applied to clipped skin at 0.4 mL or 500 mg/guinea pig (ca. 1 to 2 g/kg) three times, on a weekly basis, followed two weeks later by a challenge dose, to a naive site. Dermal sensitization was measured, as erythema with or without edema, in response to the challenge dose, at 24 and 48 hr, on a scale of 0 to 3. All of the (seven) formulations tested scored zero, i.e., were negative.

/LABORATORY ANIMALS: Acute Exposure/ A single-dose limit test was conducted using the rabbit (six of either sex), dosed at 0.5 mL/sq inch (or 0.5 g/sq inch) for 4 hr. The responses were graded. Nineteen of 20 formulations caused mild or slight irritation (Category IV); 1 showed moderate irritation at 72 hr (Category III).

/AQUATIC SPECIES/ Freshwater toxicology of sulfur on fish as follows: 16,000 ppm for 5 hr on goldfish resulted in 100% mortality under turbid water conditions; 10 to 80 ppm on goldfish resulted in a theoretical threshold; 10,000 ppm for 96 hr on mosquito fish was the resulting TLm under turbid water conditions; 1,600 for 3.5 to 5.25 hr on goldfish proved fatal under colloidal sulfur in tap water.

/AQUATIC SPECIES/ Recent literature indicates that the elemental sulfur occurring in organic extracts of sediment samples can be toxic to the bacterium Vibrio fischeri, used in standard Microtox bioassays. This observation was tested by means of the solvent extraction of 14 freshwater sediment samples from rivers tributary to Lake Geneva (Switzerland-France), measuring both Microtox toxicity and the elemental sulfur concentration of the extracts. Aliquots of these sediment extracts were further treated to remove the sulfur by adding acid-activated copper to the crude extracts; for 18 hr in one case, and for 116 hr in another. The results were a significant amount of the observed acute toxicity in the Microtox assay of 81% of sample extracts (n = 42, crude and after cleanup) was due to elemental sulfur, and despite a median decrease of 99.1% of elemental sulfur in the extracts subject to a 116-hr cleanup, sulfur toxicity was not completely excluded for 57% (8/14) of the samples.

/PLANTS/ Phytotoxic, to some extent, to a number of crops, incl cucurbits, apricots, raspberries, and certain other 'sulfur-shy' /sulfur sensitive plant/ varieties.

/FIELD STUDIES/ In the case of a 3-year field study on highbush blueberry bushes in mineral soil, sulfur amendment increased both early growth and blueberry yield. It was concluded that the effects of sulfur were probably mediated by a decrease in soil pH with corresponding increases in Mn and Fe levels. It was also found, in a lysimeter study, that increasing the sulfur content of soil led to a rise in sulfur content of plants, such as corn, wheat, barley, sunflower, and mustard.

Sulfur accounts for 15% of the inner core of the earth and 0.052% of its crust. The total sulfur content of the earth is estimated to be about 18.2X10+15 tons. The world is rich in large and highly pure deposits of elemental sulfur from which commercial sulfur can be mined. Sulfur minerals include gypsum, epsomite, miralulite, pyrite and marcasite, sphalerite, chalcopyrite, cobaltitle, pyrrhalite, galena, arsenopyrite, and pentlandite. Elemental sulfur occurs in salt domes, volcanic deposits and some deposits of calcite, gypsum, and anhydrite. In every state, whether gas, liquid, or solid, elemental sulfur occurs in more than one allotropic form. Three are relevant in nature: -2 (sulfhydryl and sulfide), 0 (elemental sulfur), and +6 (sulfate). The global sulfur cycle involves an atmospheric flux of about (140-350)X10+6 tons/annum, with (40-60)X10+6 tons as anthropogenic sulfur, in the form of sulfur dioxide, sulfuric acid, and sulfate. The rest ((100-290)X10+6 tonns/annum) involves biological decay, sea spray, and volcanism. However, the increasing acid precipitation from industrial stack emissions has seriously disturbed the natural sulfur cycle. Sulfur also paricipates in microbial cycles. Numerous microorganisms and plants use sulfate as their sole source of sulfur, converting it to organic sulfhydryl compounds in the oxidation state of -2. Many microorganisms, mainly Thiobacillus sp., can produce sulfide which under aerobic conditions is oxidized to sulfur and sulfate either spontaneously or through biochemical processes. (SRC)

/AQUATIC SPECIES/ Freshwater toxicology of sulfur on fish as follows: 16,000 ppm for 5 hr on goldfish resulted in 100% mortality under turbid water conditions; 10 to 80 ppm on goldfish resulted in a theoretical threshold; 10,000 ppm for 96 hr on mosquito fish was the resulting TLm under turbid water conditions; 1,600 for 3.5 to 5.25 hr on goldfish proved fatal under colloidal sulfur in tap water.

/AQUATIC SPECIES/ Recent literature indicates that the elemental sulfur occurring in organic extracts of sediment samples can be toxic to the bacterium Vibrio fischeri, used in standard Microtox bioassays. This observation was tested by means of the solvent extraction of 14 freshwater sediment samples from rivers tributary to Lake Geneva (Switzerland-France), measuring both Microtox toxicity and the elemental sulfur concentration of the extracts. Aliquots of these sediment extracts were further treated to remove the sulfur by adding acid-activated copper to the crude extracts; for 18 hr in one case, and for 116 hr in another. The results were a significant amount of the observed acute toxicity in the Microtox assay of 81% of sample extracts (n = 42, crude and after cleanup) was due to elemental sulfur, and despite a median decrease of 99.1% of elemental sulfur in the extracts subject to a 116-hr cleanup, sulfur toxicity was not completely excluded for 57% (8/14) of the samples.

/PLANTS/ Phytotoxic, to some extent, to a number of crops, incl cucurbits, apricots, raspberries, and certain other 'sulfur-shy' /sulfur sensitive plant/ varieties.

/FIELD STUDIES/ In the case of a 3-year field study on highbush blueberry bushes in mineral soil, sulfur amendment increased both early growth and blueberry yield. It was concluded that the effects of sulfur were probably mediated by a decrease in soil pH with corresponding increases in Mn and Fe levels. It was also found, in a lysimeter study, that increasing the sulfur content of soil led to a rise in sulfur content of plants, such as corn, wheat, barley, sunflower, and mustard.

Sulfur accounts for 15% of the inner core of the earth and 0.052% of its crust. The total sulfur content of the earth is estimated to be about 18.2X10+15 tons. The world is rich in large and highly pure deposits of elemental sulfur from which commercial sulfur can be mined. Sulfur minerals include gypsum, epsomite, miralulite, pyrite and marcasite, sphalerite, chalcopyrite, cobaltitle, pyrrhalite, galena, arsenopyrite, and pentlandite. Elemental sulfur occurs in salt domes, volcanic deposits and some deposits of calcite, gypsum, and anhydrite.

The world is rich in large and highly pure deposits of elemental sulfur from which commercial sulfur can be mined.

The increasing acid precipitation from industrial stack emissions has seriously disturbed the natural sulfur cycle(1,2). /Sulfur compounds/

Biogenic sulfur compounds originate from non-specific bacterial reduction of organic sulfur, for example plant decomposition, and from specific sulfate reducing bacteria. Sulfate-reducing microbes are strict anaerobes, while the nonspecific reducers may be found in aerobic or anaerobic environments(1). Microbial activity plays a key role in the release and leaching of trace elements such as sulfur from metalliferous peat soils from the Elba, New York region(2).

Sulfur reaches local water courses, in limited amounts by dusting of solid sulfur (state form) during transportation and handling at ports; runoff from storage areas; and accidental spills.

When spilled onto soil, molten sulfur will solidify prior to any significant movement into the soil. In solid form, sulfur is insoluble and thus cannot be transported downward to the ground water table. Traces of hydrogen sulfide represent the only aqueous phase contaminant likely to be detected.

SOIL: The weight percent of elemental sulfur in soil has been reported to range from 0.003 to 1%(1). The average amount of sulfur in soils of the conterminous US has been reported as 1600 ppm, ranging from <800 to 48,000 ppm(2).

... Soybean flour contains 14 wt% ... milk, eggs, beef, bread, beans, soybean, wheat, and peanut all contain between 1.1 and 8 wt% sulfur.

According to the 2006 TSCA Inventory Update Reporting data, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of sulfur is 1000 or greater; the data may be greatly underestimated(1).

SULFUR IS WIDELY USED & THERE ARE NUMEROUS OPERATIONS, SUCH AS SHOVELING, GRINDING, SCREENING, & BAGGING, WHERE SULFUR DUST IN CONSIDERABLE AMT IS FOUND IN THE ATMOSPHERE.

The greatest sulfur hazard is encountered in the traditional extraction of sulfur bearing rock, since the inhalation of the high concentrations of sulfur dust encountered in sulfur mines may have harmful effects on the respiratory system.

Sulfur reaches local water courses, in limited amounts by dusting of solid sulfur (state form) during transportation and handling at ports; runnoff from storage areas; and accidental spills.

According to the FDA Total Diet Study, conducted from July 1986 through April 1991, the mean daily intake of body weight (ug/kg body weight/day, age) of sulfur was as follows: 0.0064 (6-11 months); 0.0368 (2 yrs); 0.0055 (14-16 years, female); 0.0054 (14-16 years, male); 0.0053 (25-30 years, female); 0.0031 (25-30 years, male); 0.0069 (60-65 years, female); 0.0068 (60-65 years, male)(1).

Section 13. Disposal Considerations

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.

Completely empty bag into application equipment. Then dispose of empty bag in a sanitary landfill or by incineration, or if allowed by state and local authorities, by burning. If burned, stay out of smoke.

Dump into a landfill site. Recommendable method: Landfill. Not recommendable method: Thermal destruction. Peer review: Caution: sulfur could be a fire hazard and may cause bacterial degradation, landfill is recommendable for small amt only. (Peer-review conclusions of an IRPTC expert consultation (May 1985))
