SECTION VII ?HEALTH AND FIRST AID
Skin: Repeated or prolonged contact can be irritating, causing dermatitis and sensitization..
Eyes: Dust in eyes can be irritating, causing tearing and redness.
Inhalation: High dust or vapor concentrations can be harmful. Can cause a sore throat and nose, coughing, sneezing
and breathing difficulties.
Ingestion: Not a normal route of entry. However, can be harmful or fatal if swallowed.
FIRST AID PROCEDURES:
Eyes: Flush with large amounts of cool running water for at least 15 minutes with eyelids forced open. If irritation persists
obtain medical attention.
Skin: Remove contaminated clothing. Wash exposed skin with soap and water. If irritation develops and persists seek
medical attention.
Inhalation: For excessive inhalation remove to fresh air. If recovery is not rapid seek medical attention.
Ingestion: Give large quantities of milk or water. Seek immediate medical attention.
SECTION VIII ?EXPOSURE CONTROLS / PERSONAL PROTECTION
Eye Protection: Use eye protection when dispensing. Goggles or full-face shield recommended.
Respiratory Protection: Where exposure limits are exceeded and sustained use a NIOSH approved dust mask.
Confined areas, use self-contained breathing apparatus.
Ventilation: General Mechanical ventilation to prevent excessive dust accumulation.
Protective Gloves: Solvent resistant (Neoprene, Butyl, Nitrile) gloves.
Other Equipment: Protective clothing depends on potential exposure conditions and may include boots, suits or apron.
SECTION IX ?ACCIDENTAL RELEASE MEASURES
Small Spill: Stop source of spill. Salvage and recycle as much material as possible. Wet spills can be neutralized with
an alkaline material such as caustic soda. Sweep up dry material or absorb liquid residual on inert media and collect into
suitable container.
Large Spill: Plug leak at the spill. Dike area to contain spill. Salvage as much usable material as possible. Avoid
contaminating ground and surface water.
SECTION X ?DISPOSAL CONSIDERATIONS
Reuse or reprocess if possible. Waste determinations typically consider Sodium Metabisulfite contaminated materials to
