Safety & Environmental Procedures
Key Takeaways
- ESD (Electrostatic Discharge) can destroy electronic components with as little as 30 volts — always use an anti-static wrist strap connected to a grounded surface when handling components.
- When working with CRT monitors, laser printers, and power supplies, be aware of stored high voltages that can cause serious injury or death even when devices are unplugged.
- Proper lifting technique: bend at the knees, keep the back straight, hold the load close to your body, and never twist while lifting — always ask for help with heavy equipment.
- Material Safety Data Sheets (MSDS/SDS) provide critical safety information about hazardous materials including handling, storage, and emergency procedures for chemicals used in IT.
- E-waste must be disposed of properly — batteries, CRT monitors, toner cartridges, and electronics contain toxic materials and should be recycled through certified e-waste recyclers, not thrown in regular trash.

Safety & Environmental Procedures
Electrostatic Discharge (ESD) Prevention
ESD is the sudden flow of electricity between two objects caused by a static charge. It can damage or destroy sensitive electronic components with as little as 30 volts — far below what humans can feel (3,000+ volts needed to feel a static shock).
ESD Prevention Measures
| Measure | Description |
|---|---|
| Anti-static wrist strap | Worn on wrist, clip connected to grounded surface (case/mat) |
| Anti-static mat | Placed on workbench, provides grounded work surface |
| Anti-static bags | Store components in static-shielding bags |
| Self-grounding | Touch the metal case (while plugged in but powered off) before handling components |
| Humidity | Maintain 40-60% humidity (dry air increases static) |
| Avoid carpet | Carpet generates significant static — work on hard floors if possible |
Critical Rule: Always wear an anti-static wrist strap when handling circuit boards, RAM, CPUs, and other sensitive components. Even if you cannot feel a discharge, it can degrade components over time.
What NOT to Use ESD Straps With
- CRT monitors — High voltage stored in the tube
- Power supplies — Capacitors retain lethal charge
- Laser printers — Fuser assembly retains high voltage
Electrical Safety
High-Voltage Hazards
| Equipment | Danger | Safety Rule |
|---|---|---|
| CRT Monitors | Up to 25,000 volts stored in capacitor | NEVER open; certified technicians only |
| Power Supplies | Capacitors hold lethal charge even unplugged | NEVER open; replace as complete unit |
| Laser Printers | Fuser can reach 200°C (400°F), high voltage | Allow to cool, exercise caution during maintenance |
| UPS Batteries | Heavy, contain acid, produce hydrogen gas | Handle carefully, proper disposal required |
General Electrical Safety
- Always unplug equipment before servicing (except when testing requires power)
- Never work on electrical equipment with wet hands or on wet surfaces
- Use a multimeter to verify power is off before touching components
- Replace frayed or damaged power cables immediately
- Do not overload power strips or outlets
- Know the location of the circuit breaker/electrical panel in your work area
Proper Lifting Technique
IT technicians regularly move heavy equipment (servers, UPS units, printers):
| Do | Do NOT |
|---|---|
| Bend at the knees, keep back straight | Bend at the waist |
| Hold load close to your body | Extend arms with heavy load |
| Lift with your legs | Lift with your back |
| Keep your head up, look forward | Twist your body while lifting |
| Take small steps, move slowly | Rush or take large steps |
| Ask for help with heavy items (50+ lbs) | Try to carry too much alone |
Hazardous Materials
Material Safety Data Sheets (MSDS/SDS)
- Required for all hazardous materials in the workplace
- Provide information on: Chemical composition, health hazards, first aid, handling procedures, storage requirements, disposal methods, emergency procedures
- Must be readily accessible to all employees who may encounter the material
- Available from the manufacturer or online databases
Common IT Hazardous Materials
| Material | Found In | Hazard | Disposal |
|---|---|---|---|
| Lithium batteries | Laptops, phones, tablets | Fire, explosion, toxic chemicals | Certified recycler, never regular trash |
| Toner | Laser printers | Respiratory irritation, carcinogenic | Sealed container, manufacturer recycling |
| CRT phosphors | Legacy CRT monitors | Lead, other heavy metals | Certified e-waste recycler |
| LCD backlight | Older LCDs | Mercury | Certified e-waste recycler |
| Thermal paste | CPU/heatsink interface | Mild skin irritant | Clean with isopropyl alcohol, dispose properly |
| Circuit boards | All electronics | Lead solder, heavy metals | Certified e-waste recycler |
E-Waste Disposal
NEVER throw electronics in regular trash. Electronics contain toxic materials (lead, mercury, cadmium) that contaminate soil and water.
| Item | Proper Disposal |
|---|---|
| Batteries | Battery recycling center or certified e-waste recycler |
| CRT Monitors | Certified e-waste recycler (contain lead) |
| Toner/Ink Cartridges | Manufacturer recycling programs (most offer free returns) |
| Hard Drives | Secure data destruction + electronics recycler |
| Cell Phones | Manufacturer trade-in programs or certified recycler |
| Cables/Peripherals | Electronics recycling programs |
Professionalism and Communication
Professional Communication
| Principle | Description |
|---|---|
| Active Listening | Give full attention, do not interrupt, ask clarifying questions |
| Avoid Jargon | Use simple, clear language that non-technical users understand |
| Set Expectations | Provide realistic timelines and follow up as promised |
| Document Everything | Update tickets with all actions taken and findings |
| Maintain Confidentiality | Never access or share user data beyond what is needed for the task |
| Be Punctual | Arrive on time, meet deadlines, communicate delays proactively |
| Remain Calm | Even with frustrated users, stay professional and empathetic |
Dealing with Difficult Users
- Listen to their frustration without taking it personally
- Acknowledge the problem and show empathy ("I understand this is frustrating")
- Focus on solving the problem, not assigning blame
- If you cannot resolve it, escalate appropriately and explain the next steps
- Never argue, be condescending, or dismiss the user's concerns
