First Aid Measures

Ingestion

Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage

Keep containers tightly sealed. Store in a cool dry area. Take precautionary measures against static discharges. Ensure all storage areas are well ventilated.

Handling

Avoid inhalation of dust. Avoid contact with the eyes. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities. Avoid dust formation and accumulation.

Hazards Identification

Inhalation

Inhalation of dust or powder is likely to cause irritation to the mucous membranes and respiratory tract.

Skin

Dermal exposure may result in corrosive action on the skin. Skin lesions begin with epithelial cracking and the formation of slow-healing ulcers.

Eyes

The dust and powder are irritating to eyes.

Ingestion

Persistent vomiting, hematemesis and hemorrhagic gastritis due to the corrosive action of oxalic acid on the mucous membranes may occur immediately following ingestion.

Exposure Controls/Personal Protection

Personal Protection

Protective glasses, protective gloves (PVC/Rubber/Butyl rubber/Neoprene/Nitrile/ clothing to minimise exposure.

Respirators

If workplace exposure limit(s) of product or any component is exceeded (see exposure guidelines), a NIOSH/MSHA approved air supplied respirator is advised in absence of proper environmental control. OSHA regulations also permit other NIOSH/MSHA respirators (negative pressure type) under specified conditions see your industrial hygienist). Engineering or administrative controls should be implemented to reduce exposure.

Exposure Effects

Increased deep tendon reflexes, drowsiness, stupor, seizures and coma may be noted.

Poison Class

4

Fire Fighting Measures

Flash Point

>100

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Accidental Release Measures

Small spills/leaks

Avoid dust formation. Sources of ignition should be kept clear. Clean-up personnel should wear suitable clothing with protective goggles, gloves and approved dust mask. Do not flush away spills or spill area residues. Sweep oe shovel up spills together with dust binding agent or use a vacuum cleaner. Place waste in labelled drums for disposal.

Stability and Reactivity

Stability

No data.

Incompatibilities

Strong oxidizing agents.

Decomposition

Oxides of carbon.
