MSDS

4 / 7

6.1 Spill or leak:

Battery cell is sealed against electrolyte loss. Under normal handling, spillage of alkali

electrolyte will not occur. However, battery may emit electrolyte or hydrogen as if charging

or discharging rates exceed manufacturer’s recommendations or if battery has been

breached.

6.2 Personal precaution

Use personal protection recommended in Section 8.

6.3 Methods for Containment: Move battery to well ventilated area to prevent hydrogen

gas accumulation. If electrolyte leaks or spills, neutralize with a weak acid such as vinegar or

citric before proper disposal. Dispose in accordance with applicable local, state and federal

regulations.

7. HANLING AND STORAGE

No hazards during handling, no electrolyte can pour out of the sealed NI-MH cells.

Storage following SUPPO specifications: +5 to +25℃ in a 65 +- 5% relative humidity.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

8.1 Exposure Guideline

Common chemical

name/General name

ACGIH(2005)

TLVTWA BEI

Nickel, Nickel Components (As Ni)

Metal: 1.5mg/m

Cobalt Compounds (As Co) 0.02mg/ m In blood: I micro g/l

Potassium Hydroxide - -

Sodium Hydroxide - -

Lithium Hydroxide - -

8.2 Engineering Controls:

Avoid charging batteries in areas where hydrogen gas can accumulate. Use local exhaust

ventilation to maintain concentrations of hydrogen below the lower Explosive Limit (L.E.L).

Consult a qualified ventilation professional regarding the proper methods to collect and

transport flammable gases in ventilation systems. Insure proper ventilation is present during

battery disassembly to control occupation exposure to battery component particulate and

electrolyte mist and vapor.

8.3 Eye/Face Protection

Wear ANSI approved safety glasses with side shields during normal use. Wear OSHA

approved face shield with safety glasses during intentional disassembly.

8.4 Skin Protection: Wear nitrile butyl rubber, neoprene, or PVC gloves and protective

clothing during battery component disassembly. Discard contaminated work clothing

after one work day.

8.5 Respiratory protection:

None required during normal use. Use appropriate NIOSH approved respirator if airborne
