Exposure Controls/Personal Protection

Personal Protection

Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.

Exposure Effects

May be fatal if inhaled, swallowed, or absorbed through skin. May cause allergic respiratory and skin reactions. Target organs: kidneys, lungs, central nervous system, blood. Large doses of lithium ion have caused dizziness and prostration, and can cause kidney damage if sodium intake is limited. Dehydration, weight loss, dermatological effects, and thyroid disturbances have been reported. Central nervous system effects that include slurred speech, blurred vision, sensory loss, ataxia, and convulsions may occur. Diarrhea, vomiting, and neuromuscular effects such as tremor, clonus, and hyperactive reflexes may occur as a result of repeated exposure to lithium ion. Inhalation of dichromate dusts can cause ulceration and perforation of the nasal septum. Contact with breaks in the skin can cause ulceration (chrome sores). Other symptoms of exposure include erosion and discoloration of the teeth, nephritis, epigastric pain (inflammation and ulceration of the gastrointestinal tract).

Fire Fighting Measures

Fire Fighting

Use extinguishing media appropriate to surrounding fire conditions. For fires involving this material, do not enter any enclosed or confined fire space without proper protective equipment. This may include self-contained breathing apparatus to protect against the hazardous effects of the normal products of combustion or oxygen deficiency.

Fire Potential

Noncombustible.

Accidental Release Measures

Small spills/leaks

Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity

Decomposition

Reducing agents, organic materials, acid.
