Key Details
Section 2 — Hazards Identification
Under normal conditions of use, the HB3 battery pack is not classified as dangerous. Hazards arise only if the battery is ruptured, dismantled, crushed, or improperly handled. Key hazard information is summarised below.
| Hazard Category | Description |
|---|---|
| Skin Contact | Electrolyte leakage may cause soreness and skin irritation. Remove contaminated clothing and flush with soap and water for at least 15 minutes. |
| Eye Contact | Electrolyte vapour may stimulate eyes and cause inflammation. Rinse immediately with plenty of water and seek medical aid. |
| Inhalation | Vapours or mists from a ruptured battery may cause respiratory irritation. Move to fresh air; administer oxygen or artificial respiration if required. |
| Ingestion | Not anticipated under normal use. If accidental ingestion occurs, dilute with plenty of water and seek medical aid immediately. |
| Environmental Hazard | Electrolyte leakage or container rupture may release inner components into the environment. Prevent entry into soil, subsoil, or drainage systems. |
| Fire / Burst Risk | Do not dispose of battery in fire — risk of explosion. Do not short-circuit — risk of fire. |
Section 3 — Chemical Composition
The battery pack contains the following chemical constituents:
| Chemical Composition | CAS Number | Weight (%) |
|---|---|---|
| Nickel Cobalt Manganese Lithium Oxide (NMC) | 182442-95-1 | 41 |
| Graphite | 7782-42-5 | 22 |
| Electrolyte (Lithium Hexafluorophosphate) | 21324-40-3 | 16 |
| Copper | 7440-50-8 | 11 |
| Aluminium | 7429-90-5 | 5 |
| Separator (Polyethylene) | 9002-88-4 | 1 |
| Binder (PVDF) | 24937-79-9 | 1 |
| Binder Carboxymethylcellulose Sodium | 9004-32-4 | 1 |
| Binder (Styrene-Butadiene Rubber) | 9003-55-8 | 1 |
| Conductive Agent (Carbon Black) | 1333-86-4 | 1 |
Section 5 — Fire-Fighting Measures
The battery pack is non-flammable under normal conditions. However, overheating from improper use may cause combustible electrolyte fumes to be released. Recommended extinguishing agents include carbon dioxide (CO₂), dry chemical, and foam. Firefighting personnel must wear full-face filter masks or isolated breathing apparatus, along with fire-resistant protective clothing and gloves. Extinguish fires from the windward side wherever possible.
Section 6 — Accidental Release Measures
In the event of accidental release: avoid contact with skin, eyes, or clothing; ensure adequate ventilation; evacuate personnel to safe areas; and keep all persons upwind of any spill or leak. Prevent the product from entering drains, soil, or the broader environment. Collect released material and transfer to properly labelled containers.
Section 7 — Handling and Storage
- Read the product specification carefully before handling.
- Do not crush or pierce battery terminals with conductive objects.
- Do not directly heat, solder, or throw the battery into fire.
- Do not mix batteries of different types or mix new and used batteries.
- Store in a cool, well-ventilated area, away from heat sources, open flames, corrosive chemicals, food, and drink.
- Keep batteries in original packaging until use to prevent short circuit.
- Keep out of reach of children.
Section 8 — Personal Protection
| Protection Type | Requirement |
|---|---|
| Respiratory Protection | Not required under normal use. Use self-contained respiratory equipment if battery ruptures. |
| Eye / Face Protection | Not required under normal use. Wear safety goggles when handling a leaking or ruptured battery. |
| Skin and Body Protection | Not required under normal use. Use rubber apron and protective clothing when handling a ruptured battery. |
| Hand Protection | Not required under normal use. Use rubber gloves when handling a ruptured battery. |
