2. HEALTH HAZARD INFORMATION

 

Swallowed

Metallic taste in mouth. Burning sensation in throat and vomiting are typical effects. more severe poisoning causes irritation in digestive tract with abdominal pain, nausea, vomiting, ulceration and diarrhoea. May cause haemorrhaging of the digestive tract. Can be fatal.

Eye

May cause eye irritation and local inflammation, tissue destruction, corneal opacity and adhesion of the eyelid to the eye. May also cause conjunctivitis and ulcerations. Traces of sulphuric acid impurity may contribute to these effects.

Skin

May cause skin irritations and discolouration of the skin.

Inhaled

Dusts and mists (copper solutions) can cause irritation of the nasal passages and throat. Ulceration and perforation of the nasal septum is possible if inhaled in excessive quantities. These effects may be due to traces of sulphuric acid impurities.

Repeated exposure to the dust or fumes can damage the liver and/or lungs. It can also cause copper to deposit in the skin and hair, leaving a green colour. Metallic taste may also occur in the mouth. Repeated exposure can cause shrinking of the lining of the inner nose, with a watery discharge, or thickening of the skin. Exposure may also casue skin allergy or dermititis. If allergy deveops, even low future exposures may trigger a rash. Very irritating substances may affect the lungs. It is not known whether copper sulphate causes lung damage. Prolonged or repeated eye contact may cause conjunctivitis. This substance has adverse reproductive and foetal effects in animals. Copper is an essential element and its level in the body is strictly controlled. Under most conditions, excess copper is excreted in the urine and faeces.

Induce vomiting. If victim is conscious and alert, give 2 - 4 cupfuls of milk or water. Rinse mouth with water. Seek medical advise immediately.

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Seek medical attention immediately.

Remove contaminated clothng immediately. Completely decontaminate clothing, shoes and leather goods before re-use or discard. Wash affected skin with plenty of soap and water for at least 15 minutes. Seek medical attention if irritation persists.

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention.

Ensure an eye bath and safety shower are available and ready for use.

Treat symptomatically based on judgement of doctor and individual reactions of patient. Penicillamine may be of value as a chelating agent.

Oral LD50 = 300 mg/kg (Rat) ; 60 mg/kg (Dog) Oral LDLo = 1088 mg/kg (Human) ; 60 mg/kg (Dog) Dermal LD50 = not available Inhalation LC50 = not available Not listed as a carcinogen by ACGIH, IARC, NIOSH, NTP or OSHA.

 

3. PRECAUTIONS FOR USE

 

Worksafe recommends the following exposure limits : Copper, dusts and mists (as Cu) : TWA = 1 mg/m3 Copper (fume) : TWA = 0.2 mg/m3

Ensure adequate general or local exhaust ventilation to keep airborne concentrations below the permissable exposure limits.

Respiratory - always wear a NIOSH-approved respirator. Eyes - wear appropriate protective eyeglasses and/or eye/face protection. Skin - wear natural rubber gloves, apron and/or other protective clothing to minimise exposure. Wash hands and face thoroughly after handling, and before eating, drinking, smoking or using toilet facilities.

Material is non-flammable under conditions of use.

Hazard HARMFUL

R22 Harmful if swallowed.

R36/38 Irritating to eyes and skin.

S2 Keep out of the reach of children.

S22 Do not breathe dust.

Avoid generating dusts.

Vacuum or sweep up material, place into suitable labelled containers and hold for waste disposal. Wash spill residues away with copious quantities of water. Dispose in accordance to environmental regulations.

Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility.

Fire / Explosion

Material is stable under normal conditions of storage and use. Avoid high temperatures and incompatible materials. Incompatible with acetylene gas, aluminium powder, hydroxylamine, magnesium and moist air. Hazardous decomposition products include oxides of sulphur and oxides of copper. Hazardous polymerisation has not been reported.

Use equipment/media appropriate to surrounding fire conditions. Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Closed containers exposed to heat may explode. When heated to decomposition toxic fumes of sulfur dioxide are produced.
