SECTION 4. FIRST AID MEASURES

Eye Contact: Quickly and gently blot or brush chemical off face. Immediately flush the contaminated eye(s) with lukewarm,gently flowing water for 15 20 minutes, while holding the eyelid(s) open. If a contact lens is present, DO NOT delay irrigation or

attempt to remove the lens. Take care not to rinse contaminated water into the unaffected eye or onto the face. Immediatelyobtain medical attention.

Skin Contact: Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Flush with lukewarm gentlyflowing water for 5 minutes. If irritation persists, repeat flushing. Obtain medical advice. Completely decontaminate clothing,

shoes and leather goods before reuse or else discard.

Inhalation: Remove source of contamination or move victim from exposure area to fresh air immediately. If breathing has

stopped, trained personnel should begin artificial respiration and transport victim to an emergency care facility.

Ingestion:

NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victimrinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 2 8 oz. (60 240 ml) of water. If vomitingoccurs naturally, have victim rinse mouth with water again. Obtain medical advice and bring a copy of this MSDS.

SECTION 5. FIRE FIGHTING MEASURES

Fire and Explosion Hazards: This product is non-combustible and is not considered to be a fire or explosion hazard.

Extinguishing Media: Use any means of extinction appropriate for surrounding fire conditions such as water spray, carbon

dioxide, dry chemical, or foam.

Fire Fighting: Fire fighters should be fully-trained and wear full protective clothing including an approved, self-containedbreathing apparatus which supplies a positive air pressure within a full face piece mask. Do not release runoff from fire controlmethods to sewers or waterways.

Flashpoint and Method: Not Applicable.

Upper and Lower Flammable Limit: Not Applicable.

Autoignition Temperature: Not Applicable.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Procedures for Cleanup: Control source of spillage if possible to do so safely. Clean up spilled material immediately, observingprecautions in Section 8, Personal Protection. Clean up using methods which will minimize dust generation (e.g., vacuum solids,dampen material and shovel or wet sweep). Return uncontaminated spilled material to the process if possible. Placecontaminated material in suitable labelled containers for later recovery or disposal. Treat or dispose of waste material inaccordance with all local, regional, and national requirements.

Personal Precautions: Protective clothing, gloves, and a respirator are recommended for persons responding to an accidental

release (see also Section 8). Close-fitting safety goggles may be necessary in some circumstances to prevent eye contact withferrous sulphate dust.

Environmental Precautions: This product can potentially pose risks to organisms living in both the aquatic and terrestrialenvironments. Any discharge to soil and water should be prevented.

SECTION 7. HANDLING AND STORAGE

Store in sealed containers in a cool, dry area away from incompatible materials. Protect against physical damage to containers.Minimize dust generation and accumulation. Avoid breathing dust. Always practice good personal hygiene. Refrain from eating,drinking, or smoking in work areas. Thoroughly wash hands after handling and before eating, drinking, or smoking in appropriatedesignated areas only. Remove contaminated clothing and wash before reuse.

SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Protective Clothing: Coveralls or other work clothing, glasses or goggles, and gloves are recommended to prevent prolonged orrepeated direct skin contact. Close-fitting safety goggles may be required to prevent eye contact if excessive dust is generated.Workers should wash immediately when skin becomes contaminated and at the end of each work shift. Work clothing should be

removed immediately if it becomes heavily contaminated and should be changed daily and laundered before reuse if there isreasonable probability that the clothing may be contaminated.

Ventilation: Use adequate local or general ventilation to maintain the concentration of ferrous sulphate dust in the workingenvironment well below recommended occupational exposure limits.

Respirators: Where ferrous sulphate dust is generated and cannot be controlled to within acceptable levels by engineeringmeans, use appropriate NIOSH-approved respiratory protection equipment (a 42CFR84 Class N, R or P-95 particulate filtercartridge).

SECTION 10. STABILITY AND REACTIVITY

Stability & Reactivity: This material is stable and not considered reactive under normal temperatures and pressures.Hazardous polymerization or runaway reactions will not occur. This material oxidizes slowly in moist air to form a yellow-browncoating of basic ferric sulphate. This may lower the oxygen concentration inside confined spaces. Aqueous solutions are oxidizedslowly by air when cold, rapidly when hot. The rate of oxidation is increased by addition of alkali or exposure to light.

Incompatibilities: Alkalis, soluble carbonates, and oxidizing agents, gold and silver salts, lead acetate, lime water, potassiumiodide, sodium borate, potassium and sodium tartrate, tannin.

Hazardous Decomposition Products: Excessive heat may liberate sulphur dioxide, which is toxic and a strong respiratory/ eyeirritant. High temperature operations such as oxy-acetylene cutting, electric arc welding or arc-air gouging on surfaces coatedwith ferrous sulphate may generate irritating and toxic sulphur dioxide fumes.

SECTION 11. TOXICOLOGICAL INFORMATION

General: A skin, eye and mucous membrane irritant. Only moderately toxic by ingestion. Hazards are largely those from acuteexposure or direct contact rather than chronic or repeated low level exposure.

Acute:Skin/Eye: Exposure will cause eye irritation with possible discomfort, tearing, redness or itching. If left untreated it may causeburns and some eye tissue damage. Direct skin contact will cause slight to moderate skin irritation with discomfort, rash anditching.

Inhalation: Inhalation of ferrous sulphate dust may be irritating to the respiratory system. Symptoms may include coughing,sneezing and/or shortness of breath.

Ingestion: Ingestion may result in irritation of the esophagus and gastro-intestinal disturbances (gastric distress, colic,constipation, diarrhea). Large amounts of ferrous sulphate are toxic but, in adults, fatalities are rare and almost exclusivelysuicidal. Smaller doses are much more toxic to children and young adults, particularly between 12 and 24 years.

Chronic: Repeated exposure to ferrous sulphate may increase iron levels in the liver, spleen and lymphatic system. Massivedoses may produce damage to these organs. Ferrous sulphate is not listed as a human carcinogen by the Occupational Safety


4/5


and Health Administration (OSHA), the National Toxicology Program (NTP), the International Agency for Research on Cancer(IARC), or the American Conference of Governmental Industrial Hygienists (ACGIH).

SECTION 12. ECOLOGICAL INFORMATION

This product has high water solubility and has acidic properties; both of these characteristics have the potential to render theproduct toxic to aquatic and terrestrial organisms, under specific conditions. As well, in aquatic and terrestrial environments, theproducts ferrous iron content will oxidize, consuming oxygen; the resultant hydrolysis reactions can generate additional acidity,and can also produce ferric hydroxide precipitates, which may be harmful to aquatic organisms.

SECTION 13. DISPOSAL CONSIDERATIONS

If material cannot be returned to process or salvage, dispose of in accordance with applicable regulations. Empty and thoroughlyclean all residues from containers before reuse or disposal.
