No adverse health effects expected if the product is handled in accordance with this Safety Data Sheet and the product label. Symptoms that may arise if the product is mishandled are:
ACUTE EFFECTS -
SWALLOWED: Swallowing large amounts may cause nausea, vomiting and abdominal pain.
EYE: A Moderate to severe eye irritant.
SKIN: Contact with skin may result in moderate irritation.
INHALED: Exposure to dust will result in respiratory irritation. Under certain circumstances, sulphur dioxide may be generated which will also irritate the respiratory tract.
CHRONIC EFFECTS: THIS PRODUCT CAN SENSITISE THE SKIN AND/OR RESPIRATORY TRACT OF ALLERGIC PERSONS.
FIRST AID MEASURES
Remove to fresh air. Get medical attention for any breathing difficulty.
Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.
Not expected to require first aid measures.
Wash thoroughly with running water. Get medical advice if irritation develops.
Fire Fighting Measures
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
Special Information: Use protective clothing and breathing equipment appropriate for the surrounding fire.
Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Small amounts of residue may be flushed to sewer with plenty of water.
Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Exposure Controls/Personal Protection
Airborne Exposure Limits: None established.
Ventilation System: In general, dilution ventilation is a satisfactory health hazard control for this substance. However, if conditions of use create discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to the dust or mist is apparent, a half-face dust/mist respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
