and water. Contact with metals may produce toxic sulphur dioxide fumes and may
release flammable hydrogen gas.
HAZARDOUS DECOMPOSITION OF BY-PRODUCTS:
Sulphuric Acid
: Excessive overcharging or fire may create Sulphur trioxide, carbon
monoxide, sulphuric acid mist, sulphur dioxide, and hydrogen.
Lead Compounds:
Contact with strong acid or base or presence of nascent hydrogen
may generate highly toxic arsine gas.
8.CONTROL MEASURES
RESPIRATORY PROTECTION (SPECIFIC TYPE): Respirator required when PEL is
exceeded or employee witnesses respiratory irritation. (see Section 6, Health Hazard
Data).
VENTILATION:
Must be provided when charging in an enclosed area. (29CFR1910178(g) and
.305(j)(7))
Mechanical (general): Acceptable at 1 to 4 air exchanges/hour or to maintain air
concentrations below the PEL.
Local Exhaust: Preferred
Other: Local building/fire codes may require explosion proof fans and equipment.
PROTECTIVE GLOVES: Acid resistant
EYE PROTECTION: Preferred, safety glasses, goggles, face shield
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Acid resistance aprons, boots
and protective clothing
WORK HYGIENIC PRACTICES: Good personal hygiene and practices are mandatory.
9. SAFE HANDLING PRECAUTIONS
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
(SULPHRUIC ACID):
Dilute spill cautiously with five to six volumes of water and gradually neutralize with
sodium bicarbonate soda ash or lime. When exposure level is not known, wear NIOSH
approved positive pressure self-contained breathing apparatus. Reference North
American Emergency Response Guidebook, #154.
PRECAUTION TO BE TAKEN IN HANDLING AND STORAGE:
Storage away form reactive material as defined in Section 5, Reactivity Data. Place
cardboard between layers of stacked batteries to avoid damage and short circuit. Do
not allow metallic materials to simultaneously contact both terminals.
OTHER PRECAUTION:
Sodium bicarbonate, soda ash, hand, or lime should be kept in same general area for
emergency use. Keep away from sources of ignition during charging see Section 4 on
generation of hydrogen gas. If battery case is broken, avoid direct contact with
internal components.
