First Aid Measures

Ingestion
The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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. Pesticides - remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Irritation - treat dermal irritation or burns with standard topical therapy
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
Store in a dry and well ventilated place away from direct sunlight. Keep containers closed when not in use.
Handling
Wear protective work clothing. Wash thoroughly at the end of the workshift. Do not take contaminatedwork clothing home. Contaminated work clothing should be laundered by individuals sho have been informed of the hazards of exposure to Mica. Do not eat, smoke, or drink where Mica is handled, processed, or stored. Wash hands carefully prior to eating, drinking, smoking, or using toilet.

Hazards Identification

Inhalation
Can affect you when breathed in. Repeated high exposure to the dust can irritate the lungs and may cause scarring (fibrosis). This causes an abnormal chest x-ray, cough and shortness of breath.
EC Safety Phrase
S 22

Exposure Controls/Personal Protection

Personal Protection
Prevention of worker exposure consists primarly in adequate dust control. Workers in certain particularly exposed jobs should be equipped with masks & goggles if the general & exhaust ventilation facilities do not ensure that concn of dust are maintained below max permissable levels.
Respirators
Dust mask.
Exposure Effects
Some silicas have been shown to cause cancer in animals. The risk of cancer in humans from Mica is unclear at this time. According to information presently available, Mica has not been tested for its ability to effect reproduction.
Poison Class
F (Not subject to toxicity classification)

Fire Fighting Measures

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
Clean up personnel should wear full protective clothing including respiratory protection in dusty environments. Avoid raising dust. Do not dry sweep up spilled material. Use a vacuum or a wet method to reduce dusting during cleanup. When vavcuuming, a high efficiency particulate air (HEPA) filter should be used, not a standard shop vacuum. Transfer spilled material to suitable containers and hold for later disposal.

Stability and Reactivity

Stability
Stable.
Incompatibilities
Strong oxidizing agents.
Decomposition
No data.
