Hydrogen
--
LEL=4.1%
Sealed batteries can emit hydrogen only if over charged
(float voltage> 2.4 VPC). The gas enters the air through
the vent caps. To avoid the chance of a fire or explosion,
keep sparks and other sources of ignition away from the
battery. Extinguishing Media: Dry chemical, foam, CO2
Fiberglass

SECTION 6: HEALTH HAZARD DATA
Battery is considered as sealed non-spillable one. Under normal operating conditions, the materials sealed inside should not be
hazardous to people’s health. Only when these materials exposed during production or under case broken condition or being
extremely heated (fired), they may be hazardous to people’s health.
Routes of Entry:
Sulfuric Acid: Harmful by all routes of entry.
Lead Compounds: Hazardous Exposure can occur only when product is heated, oxidized, or otherwise processed or damaged
to create dust, vapor or fume.
Inhalation:
Sulfuric Acid: Breathing sulfuric acid vapors and mists may cause severe respiratory problems.
Lead Compounds: Dust or fumes may cause irritation of upper respiratory tract or lungs.
Fiberglass Separator: Fiberglass is an irritant to the upper respiratory tract, skin and eyes. For exposure up to 10F°/ use MSA
Comfoll with type H filters. Above 10F use Ultra Twin with type H filter. This product is not considered carcinogenic by NTP
or OSHA.
Skin Contact:
Sulfuric Acid: Severe irritation, burns and ulceration.
Lead Compounds: Not absorbed through the skin.
Ingestion:
Sulfuric Acid: May cause severe irritation of the mouth, throat, esophagus, and stomach.
Lead Compounds: May cause abdominal pain, nausea, vomiting, diarrhea, and severe cramping. Acute ingestion should be
treated by a physician.
Acute Health Hazards:
Sulfuric Acid: Severe skin irritation, burns, damage to cornea may cause blindness, upper respiratory irritation.
Lead Compounds: May cause abdominal pain, nausea, headaches, vomiting, loss of appetite, severe cramping, muscular aches
and weakness, and difficulty sleeping. The toxic effects of lead are cumulative and slow to appear. It affects the kidneys,
reproductive and central nervous systems. The symptoms of lead overexposure are listed above. Exposure to lead from a
battery most often occurs during lead reclamation operations through the breathing or ingestion of lead dust or fumes.
