ā ļø Critical Safety Rules - Never Skip These
- 1. Always disconnect power: Remove battery and unplug all power sources before starting
- 2. Discharge capacitors: Wait 30+ minutes after unplugging, press power button to discharge
- 3. Ground yourself: Use anti-static wrist strap connected to ground
- 4. Never force components: If something doesn't move easily, you're doing it wrong
- 5. Document everything: Take photos before each disassembly step
- 6. Keep liquids away: No drinks or liquids near work area
- 7. Proper ventilation: Work in well-ventilated area when using heat or chemicals
Electrostatic Discharge (ESD) Protection
ā” Understanding ESD Damage
- ā¢ Human body can generate 35,000+ volts of static electricity
- ā¢ Components can be damaged by as little as 30 volts
- ā¢ Damage may not be immediate - can cause future failures
- ā¢ Most sensitive: CPUs, RAM, motherboards, SSDs
ā Proper ESD Setup
- ā¢ Anti-static mat connected to ground
- ā¢ Wrist strap with 1MĪ© resistor
- ā¢ Humidity level 40-60%
- ā¢ Cotton clothing (avoid wool/synthetics)
- ā¢ Touch grounded metal before starting
ā ESD Hazards to Avoid
- ā¢ Carpeted work areas
- ā¢ Plastic bags and bubble wrap
- ā¢ Synthetic clothing materials
- ā¢ Low humidity environments
- ā¢ Moving around while working
Safe Tool Usage
š§ Screwdriver Safety
- ā¢ Use correct size - never force mismatched screwdrivers
- ā¢ Apply steady pressure straight down
- ā¢ Magnetic tips prevent dropped screws
- ā¢ Keep organized with magnetic tray
š„ Heat Gun/Soldering Safety
- ā¢ Temperature control: 60-80Ā°C for adhesive, 350Ā°C for soldering
- ā¢ Keep moving to avoid hot spots
- ā¢ Use heat-resistant mat underneath
- ā¢ Proper ventilation for fumes
- ā¢ Never leave unattended while hot
šŖ Prying Tool Safety
- ā¢ Use plastic tools to prevent shorts
- ā¢ Work slowly around edges
- ā¢ Multiple thin tools better than one thick
- ā¢ Watch for hidden clips and cables
š Lithium Battery Safety
ā ļø Lithium batteries can catch fire or explode if damaged!
- ā¢ Never puncture or bend batteries
- ā¢ Discharge below 25% before removal
- ā¢ Use plastic tools only near batteries
- ā¢ If battery is swollen, stop immediately
- ā¢ Keep sand/fire extinguisher nearby
- ā¢ Store removed batteries in fireproof container
- ā¢ Dispose at proper recycling centers only
š§Ŗ Chemical & Cleaning Safety
Safe Chemicals
- ā¢ Isopropyl alcohol (90%+)
- ā¢ Distilled water
- ā¢ Compressed air (hold upright)
- ā¢ Microfiber cloths
- ā¢ Electronic contact cleaner
Never Use
- ā¢ Acetone on plastics
- ā¢ Water on powered components
- ā¢ Paper towels (leave residue)
- ā¢ WD-40 on electronics
- ā¢ Harsh solvents
šØ Emergency Procedures
Electric Shock:
- ā¢ Do not touch victim if still in contact with power
- ā¢ Turn off power at breaker
- ā¢ Call emergency services
- ā¢ Begin CPR if trained
Battery Fire:
- ā¢ Evacuate area immediately
- ā¢ Use Class D fire extinguisher or sand
- ā¢ Never use water on lithium fires
- ā¢ Call fire department
Chemical Exposure:
- ā¢ Flush affected area with water 15+ minutes
- ā¢ Remove contaminated clothing
- ā¢ Seek medical attention
- ā¢ Keep chemical container for reference
