Chapter 2: Install computer network

Network installation is a critical task for ICT technicians, requiring not only technical skills but also a strong emphasis on safety. In Kenya, where ICT infrastructure supports key sectors such as healthcare, education, banking, and government services, ensuring safe network setup protects personnel, equipment, and data integrity. This chapter focuses on essential safety measures that technicians must observe during network installation, covering personal protective equipment, cable management, electrical safety, and fire safety.

2.1 Safety measures

A network installation brings together mains electricity, work at height, sharp tools, dust, heavy racks and, in equipment rooms, a real risk of fire. Safety measures are the planned habits and equipment that stop these hazards from injuring people or damaging equipment. The technician works down a simple order of control: remove the hazard where possible (switch the circuit off, route the cable away from the walkway), then guard against what remains, and use personal protective equipment as the last layer.

Before every job the technician carries out a short risk assessment: walk the site, list the hazards (live circuits, ceiling voids, ladders, public walkways, heat, dust), decide who could be harmed, and write down the controls to use. In Kenya the Occupational Safety and Health Act, 2007 places duties on both employers and workers: employers must provide a safe workplace and the protective equipment the work needs, and workers must follow safe procedures and use what is provided. A self-employed technician carries both duties for the people on the same site.

2.1.1 Personal Protective Equipment (PPEs)

Personal protective equipment is clothing and gear worn to reduce exposure to the hazards that remain after the site has been made as safe as practical. For a network technician the main exposures are dust and insulation fibres from ceiling voids, cuts from cable and tools, electric shock, static discharge that damages equipment, eye strain from long screen work, and strain injuries from poor posture. Each item below answers one of these exposures, and no single item covers them all.

Other protective equipment on site

Some jobs call for protective equipment beyond the items named in the headings below. A job for a cyber café refit in an old building, for example, may need all of the following in one day.

• Safety glasses or goggles: Protect the eyes from dust when drilling into walls and ceilings, from copper snips flicking off cable ends, and from glass slivers when cleaving or cutting fibre.
• Safety boots: A steel or composite toe-cap protects against dropped racks, switches and tools, and a slip-resistant, non-conductive sole helps on dusty floors and near live circuits.
• Hard hat: Worn on construction and refurbishment sites and when working under other trades or in roof spaces, where tools, brackets and debris can fall.
• High-visibility vest: Makes the technician easy to see in a loading bay, car park, plant room or poorly lit corridor where vehicles and trolleys move.
• Hearing protection: Hammer drills, core drills and generators are loud enough to damage hearing over time, so earplugs or earmuffs are worn during these tasks.
• Fall protection: Ladders, platforms and roof or mast work for outdoor wireless links need stable footing, a second person to foot the ladder and, at height, a harness fitted and used by someone trained to do so.

Choosing, inspecting and replacing PPE

The risk assessment decides which equipment a job needs, and the equipment must fit the person wearing it: loose gloves, oversized glasses or a badly fitted mask give a false sense of protection. Inspect each item before use. Look for tears and holes in gloves, cracked or scratched lenses, worn soles, frayed straps on harnesses and a hard hat that has been struck or has crazed (cracked) shell.

Damaged equipment is replaced, not repaired with tape. Disposable items such as dust masks and single-use gloves are thrown away after the task and are never washed or reused. Reusable items are cleaned according to the maker's instructions and stored dry and clean, away from sunlight and chemicals. Every technician on the site is shown how to put on, adjust, remove and look after each item.

2.1.1.1 Overall/apron/dust coat

An overall, apron or dust coat protects the skin and the technician's own clothes from dust, insulation fibres, rust flakes and grease met in ceiling voids, risers and floor ducts. It also stops loose clothing from catching on racks and cable trays. A technician installing cabling above the ceiling of a clothing factory floor, for example, comes down covered in lint and fibreglass dust unless a coat is worn over normal clothes.

• Fabric: Cotton or a flame-resistant fabric is preferred, because some synthetic fabrics melt onto the skin if they catch fire and build up static charge.
• Fit: The coat is close enough not to snag on rack edges, with cuffs fastened and no dangling ties, belts or lanyards near fans and moving parts.
• Antistatic coat: When equipment is opened up, a coat made with conductive threads reduces static build-up on the body (see Antistatic equipment).
• Cleaning: The coat is washed regularly, and dust is not shaken off indoors where it will settle on equipment.
• Removal: The coat is taken off before entering a clean equipment room or office, so the dust stays outside.

2.1.1.2 Antiglare screens

An antiglare screen is a matt filter or screen coating that reduces reflected light on a monitor or laptop display. Technicians spend long periods reading configuration output, diagrams and test results on screens in rooms with bright windows, white walls or overhead lights, and glare forces the eyes to work harder, causing headaches and tiredness. A matt screen filter, an antiglare coating or a screen hood used outdoors helps; so does placing the screen at right angles to windows rather than facing or backing onto them.

Antiglare measures work together with the other eye-care habits: set the display brightness close to the room's brightness, increase text size instead of leaning forward, and look away from the screen regularly. A common rule is the 20-20-20 habit: every 20 minutes look at something about 6 metres away for 20 seconds. Antiglare or blue-light-filtering spectacles are a personal choice and are not a substitute for these habits.

2.1.1.3 Dust mask

A dust mask filters fine particles from the air that the technician breathes. Drilling concrete or brick, lifting old ceiling boards and disturbing insulation or long-settled dust in a riser release particles that irritate the lungs and, over years, can cause lasting harm. A technician pulling cable through the roof space of a hardware shop that has never been cleaned needs a mask each time.

Masks are rated by how much they filter. In the European rating, FFP1 filters the least, FFP2 filters at least 94 per cent of fine particles, and FFP3 filters at least 99 per cent; the similar American N95 filters at least 95 per cent. Use FFP2 or better for drilling masonry and disturbing old insulation, and ask the employer or a safety officer when the dust is of an unknown or hazardous type (for example, suspected asbestos in old roofing, which must not be disturbed at all). To work, a mask must seal against the face: facial hair under the seal and a loose strap both let unfiltered air in. A disposable dust mask is single-use: discard it when it is damp, damaged, hard to breathe through or after the task.

2.1.1.4 Gloves

Gloves protect hands from cuts, abrasions, splinters, hot surfaces and chemical contact. The type must match the task, because a glove that helps with one hazard can create another.

• General work gloves: Leather or coated fabric gloves for pulling cable, lifting racks and handling trunking, which has sharp cut edges.
• Cut-resistant gloves: Worn when stripping armoured cable and cutting metal trunking or when handling sharp metal edges on rack ears.
• Single-use nitrile gloves: Worn for cleaning with solvents and handling fibre cleaning fluids; they are thrown away after use.
• Insulating gloves: Rated for a stated voltage and tested at intervals, they are used only by competent people for specific electrical work; ordinary rubber or work gloves give no real protection from mains voltage.
• When not to wear gloves: Never wear loose gloves near rotating drills, saws or fan blades, because they can pull the hand in. Fine work, such as seating tiny fibre connectors, is also done with bare, clean hands or thin gloves.

2.1.1.5 Antistatic equipment

Static electricity builds up on a person walking on carpet or synthetic flooring and discharges on contact with metal. A discharge too small to feel can still damage the circuits in network cards, memory modules, switch line cards and small-form-factor pluggable (SFP) modules, sometimes causing a failure only weeks later. Antistatic equipment keeps the technician and the component at the same electrical potential so that no discharge passes through the component.

• Antistatic wrist strap: Worn snugly on bare skin and clipped to an unpainted metal part of the chassis or to a proper earthing point. The coiled lead contains a resistor, commonly about 1 megohm, which limits current to the body.
• Antistatic mat: A dissipative mat on the bench, connected to earth, on which components are placed while being worked on.
• Antistatic bags: Cards and modules are stored and moved in the silver-grey shielding bags and are taken out only at the earthed work area.
• Handling habits: Hold cards by their edges, touch the chassis before touching a component, and never slide a component across carpet or plastic.
• Safety limit: A wrist strap is for working on de-energised equipment. It is never worn when working on exposed mains voltage, where its connection to earth would be a hazard.

2.1.1.6 Ergonomics

Ergonomics is the study of fitting the work and the workplace to the person, in order to prevent strain injuries. Network installation involves awkward positions: kneeling at floor boxes, reaching overhead to run cable, crouching in racks and carrying heavy equipment. Over time poor posture and repeated force cause back, neck, shoulder and wrist injuries that no PPE prevents.

• Lifting: Bend the knees, keep the load close to the body, avoid twisting, and use a trolley or a second person for rack-mounted servers, UPS units and drums of cable, which can be heavy.
• Working at height: Work from a stable platform at a comfortable height instead of stretching above shoulder level, and rotate tasks so that the same arm is not overhead for hours.
• Tool choice: Use tools with comfortable grips and ratcheting action, such as ratcheting crimpers and punch-down tools with cushioned handles, and take short breaks between repeated actions.
• Desk and screen set-up: For configuration work, place the screen with its top at or slightly below eye level and about an arm's length away, keep the elbows near 90 degrees, and rest the feet flat on the floor or a footrest.
• Breaks and variety: Stand, stretch and walk briefly at regular intervals, and mix sitting tasks with moving tasks.

2.1.1.7 First AID kit

A first aid kit is a clearly marked container of supplies for treating minor injuries and keeping a casualty stable until help arrives. A technician cabling a farm packing-shed office may be far from medical help, so the kit travels with the tool bag and is kept at the base site. Using the kit in an emergency is covered under Emergency procedures; this section covers what the kit holds and how it is kept ready.

Check the kit regularly (for example monthly and after each use), replace anything used or past its expiry date, and keep it where everyone can reach it, marked with a white cross on a green background. At least one person on the site should be trained as a first aider, and a printed guide inside the lid helps everyone else.

2.1.2 Cable management

Cable management is the planned routing, support, separation and identification of cables so that they stay safe, protected and easy to work on. Poorly managed cables cause trips and falls, are crushed or cut, hide faults, block airflow in racks, and can feed a fire through a wall opening. This section treats cable management as a safety measure; how the work is finished neatly during installation is covered under Application of cable management best practices.

Methods of keeping cables safe

• Trays and ladder racks: Carry cables overhead or along walls, off the floor and away from foot traffic, with supports spaced so that cables do not sag.
• Conduit and trunking: Enclose cables in the places where they could be crushed, cut or touched, such as along walls, across doorways and in public areas.
• Floor covers and ramps: Where a cable must cross a walkway temporarily, cover it with a floor cover so that it does not become a trip hazard, and remove it as soon as the work is complete.
• Ties and straps: Hook-and-loop straps hold bundles without squeezing; tight plastic ties can damage cables over time.
• Colour coding: Different jacket or patch cord colours for different uses (for example, a distinct colour for the camera network) reduce mistakes when cables are moved.

2.1.2.1 Proper routing

Proper routing means choosing a cable's path so that it is protected from damage, kept apart from hazards and interference, and kept easy to follow and to repair. A route that works on the drawing may still be unsafe on site, so the technician walks it before cutting any cable.

• Away from power: Keep data cables apart from mains cables, as the wiring standards and the manufacturer's data sheet specify, because power cables cause electrical interference and a damaged power cable could energise a data cable. Where they must cross, cross at right angles.
• Away from interference sources: Avoid parallel runs beside fluorescent light fittings, motors, lift equipment and large transformers.
• Away from walkways and heat: Use ceiling or wall routes in preference to the floor, and keep cable away from hot pipes, boiler flues and air outlets of heavy equipment.
• Respect the bend radius: Do not bend a twisted pair cable tighter than the maker allows, commonly four times the outer diameter of the cable, nor kink or crush it with ties and clips.
• Support properly: Do not hang cable from sprinkler pipes, ceiling hangers, other services or ceiling tiles; use supports installed for the purpose.
• Fire stopping: When a cable passes through a fire-rated wall or floor, the opening is sealed again with approved fire-stop material, and cables used in air-handling spaces are of the low-smoke, zero-halogen or plenum type that the building rules require.

2.1.2.2 Labelling

Labelling means putting a clear, durable and unique identifier on every cable, port, patch panel position and equipment item, so that anyone can tell what a cable connects before touching it. In a rack of 48 identical-looking patch cords, a wrong guess can unplug the wrong service, and in an emergency an unlabelled mains or data cable cannot be quickly identified.

• Both ends: Label each cable at both ends, close to the connector and visible without moving other cables.
• Unique and consistent: Use one scheme across the site, for example a code of room, rack, panel and port such as R1-P2-14 for rack 1, panel 2, port 14, written the same way in the drawings.
• Durable labels: Use printed self-laminating or heat-shrink labels. Handwriting with marker pen fades and smudges.
• Equipment and power: Label racks, switches, patch panels, power outlets and circuit-breaker positions as well as cables.
• Matches the records: Each label corresponds to an entry in the cable schedule, which is part of the network documentation.

2.1.3 Electrical safety

Electrical hazards are among the most dangerous on a network site, because a mains shock can cause burns, injury or death, and a faulty circuit can start a fire. Kenyan mains supply is nominally 240 volts at 50 hertz single-phase and 415 volts three-phase, and the plugs are the British three-pin type with a fuse. Network installers work close to this supply when they connect racks, UPS units and power strips, so they must treat every unproven cable as live.

Common electrical hazards in network installation

• Exposed live conductors: Damaged insulation, open junction boxes and loose terminals can cause shock if touched.
• Overloaded circuits and power strips: Too many devices on one circuit cause overheating and possible fire.
• Faulty equipment and leads: Damaged power supplies, frayed leads and broken plugs introduce a shock risk.
• Missing or poor earthing: Without a good earth connection, a fault can leave a rack or case at a dangerous voltage.
• Wet conditions: Water, damp floors and rain on outdoor installations greatly increase the risk of shock.

Safe isolation and working procedure

Before working on equipment or its supply, the technician switches off and isolates the supply, locks the isolator or breaker off and attaches a tag with their name (lock-out, tag-out), and then proves the circuit dead using a voltage tester that has itself been checked on a known live source before and after. Only a licensed electrician carries out work on fixed mains wiring and distribution boards; a network technician does not open distribution boards or alter mains circuits. Keep the work area dry, use a stable non-conductive ladder, and never work alone on live or suspect equipment.

Earthing and bonding

Earthing connects exposed metal parts, such as rack frames and cable trays, to the earth of the building so that a fault current flows to earth and trips the protective device, instead of passing through a person. Rack frames, cable trays and metallic enclosures are bonded together and connected to the building earth by a licensed electrician. Telecommunications bonding standards exist for this purpose and the installer follows the one specified for the site. Surge protection devices help protect equipment from lightning and mains surges, which is important in lightning-prone areas.

Residual current devices

A residual current device (RCD) compares the current going out and coming back along the live and neutral wires and cuts the supply within milliseconds if a small difference shows that current is leaking, perhaps through a person. An RCD that trips at 30 milliamperes is the usual rating for protection against shock. Fit RCDs on circuits feeding equipment rooms, work benches and temporary supplies, and press the test button regularly to prove it still works.

2.1.3.1 Use of insulated tools

Insulated tools have handles covered by a tested non-conductive material to protect the user if the tool touches a live conductor. Screwdrivers, pliers, cutters and wire strippers used in distribution boards, power supplies and wiring cabinets should be insulated and rated for the voltage involved, commonly 1000 volts AC, with the voltage rating marked on the handle.

• Look for the marking: Quality insulated tools carry the rating and the international mark for 1000 volt tools on the handle, and are tested by the maker.
• Check before every use: Look for cuts, cracks, burns and exposed metal under the insulation; a damaged tool is taken out of use.
• Do not modify: Never file, drill or tape over the insulation, and do not use an insulated tool as a hammer.
• Insulation is the last defence: The first defence is to isolate the supply. Insulated tools are for protection against accidental contact and do not make it safe to work on live circuits.
• Store carefully: Keep them in a roll or case so that they are not nicked by other tools.

2.1.3.2 Electrical equipment power ratings

A power rating is the electrical load a device draws, or the load a circuit, plug, strip or UPS can safely supply. It is printed on the device label as watts (W), or as volts and amperes (V and A), and sometimes as volt-amperes (VA). The technician adds up the loads before connecting equipment, so that no cable, strip or UPS is overloaded.

Power in watts is volts multiplied by amperes. Equipment labels often show a range, such as input 100 to 240 V, 50/60 Hz, 1.5 A, which means the power supply works on Kenyan 240 V mains as well as lower voltages.

Worked example: a small rack in a printing press office holds a router (18 W), two switches (35 W each), a file server (350 W) and a network storage unit (60 W).

Total load = 18 + 35 + 35 + 350 + 60 = 498 W

Current at 240 V = 498 ÷ 240 = 2.075 A

A 13 A plug fuse limits a plug at 240 V to 13 × 240 = 3,120 W. The 498 W load uses about 16 per cent of that limit, so a good quality 13 A power strip can carry it. A continuous load is normally kept below about 80 per cent of the rating, which is 0.8 × 3,120 = 2,496 W.

A UPS (uninterruptible power supply) is rated in VA, and its usable power in watts is lower because of its power factor. A UPS marked 1,000 VA and 600 W cannot run a 498 W load comfortably, since 498 ÷ 600 is 83 per cent of its rating, and it would give little spare capacity. A UPS marked 1,500 VA and 900 W loads to 498 ÷ 900 = 55 per cent and leaves room to grow.

Power over Ethernet (PoE) adds another rating: the switch has a total PoE power budget, and each powered device draws from it. A class 4 port of a PoE+ (IEEE 802.3at) switch can supply up to 30 W, so a switch with a 370 W PoE budget can power 12 such access points (12 × 30 = 360 W) but not 13 (13 × 30 = 390 W).

2.1.4 Fire safety

Fire in a network or equipment room can destroy equipment and data in minutes, and smoke can injure people far from the flames. Fire safety is the combination of preventing a fire, detecting it early, raising the alarm, and fighting or escaping it correctly. The Occupational Safety and Health Act, 2007 and the fire risk reduction rules made under it require workplaces to take steps for fire safety, and a technician working on site follows the premises' fire rules in addition to the safe habits below.

Common causes of fire in network environments

• Electrical faults: Overheating plugs, damaged leads and loose connections.
• Overloaded power strips: Daisy-chaining strips and plugging heavy loads into one outlet.
• Poor ventilation: Blocked vents, racks without airflow and dust build-up make equipment overheat.
• Faulty batteries and UPS units: Swollen or old batteries can overheat and burn.
• Combustible storage: Cardboard boxes, packaging and spare cable stored in the equipment room feed a fire.

Fire prevention strategies

Inspect electrical installations and leads regularly, stop using damaged cables, keep the load within the rating of each circuit, and keep equipment room vents clear. Keep the equipment room tidy: no cardboard, packaging or spare stock stored there, and no cooking or smoking. Switch off and unplug heat-producing tools after use. Keep a record of inspections and fix faults found without delay.

Fire detection and alarm systems

Smoke detectors and heat detectors in equipment rooms give early warning, and where an equipment room is unattended they are linked to the building alarm so that people are told at once. Very early warning systems sample the air continuously and detect smoke before it is visible. Some rooms also have gaseous fire suppression systems that discharge a clean agent or inert gas; people leave the room before discharge, so the alarm and exit routes matter.

Firefighting equipment and procedures

• Fire extinguishers: Placed near exits and equipment rooms, of a type that suits the fires expected (see Fire extinguishers).
• Fire blankets: Used to smother small fires, such as a burning waste bin, by cutting off the air.
• Evacuation plans: Exit signs, marked routes and an assembly point, with drills so that everyone knows the way out.
• Training: Technicians and staff learn how to use the extinguishers and when not to fight a fire. If the fire is growing, smoky or blocks the exit, leave and raise the alarm.
• Emergency numbers: Fire brigade and emergency numbers are posted by the telephone and stored in mobile phones.

2.1.4.1 Classes of fires

Fires are grouped into classes by the kind of fuel burning, because the correct way to put out one class can make another worse. The classes below are those of the British and European system; the American system uses different letters, as noted below.

Electrical fires are not a separate class in this system. A fire in live electrical equipment is fought by first switching off the power if it is safe to do so, and only then by using an extinguisher that is safe on electrical equipment; once the electricity is off, the fire is burning Class A or B material. In the American system, class C means energised electrical equipment and class K means cooking oils, so read the label on imported extinguishers carefully.

2.1.4.2 Fire extinguishers

A fire extinguisher is a portable container holding an agent that is discharged under pressure at the base of a small fire. Using the wrong type is dangerous: water on a live electrical fire conducts electricity back to the user, and water on burning oil spreads the fire.

Extinguishers are red with a colour zone or label showing the type; older ones may have a whole body colour, so always read the label. To use one, remember the word PASS:

1. Pull the safety pin.
2. Aim the nozzle at the base of the flames, not at the top.
3. Squeeze the handle to discharge.
4. Sweep the nozzle from side to side across the base of the fire.

Fight a fire only if it is small, you have a clear exit behind you and you have been trained. Extinguishers are inspected regularly by the user and serviced at the intervals the supplier specifies, and a discharged or damaged unit is replaced.

2.1.5 Emergency procedures

An emergency procedure is a pre-agreed set of actions to take when someone is injured, a fire starts or a serious fault occurs, so that nobody has to decide what to do while under stress. A technician on a site such as a tour company's new office knows, before the first cable is pulled, where the first aid kit is, where the exits and assembly point are, who to call and how to stop the work safely.

2.1.5.1 First AID kit

The first aid kit is used straight away while help is on the way. The notes here are a summary and do not replace a certified first aid course, which every installer should attend.

Where a person has received an electric shock:

1. Do not touch the person while they may still be in contact with the supply.
2. Switch off the supply at the isolator or breaker, or unplug the equipment if that is safe, or push the person away with a dry non-conductive object such as a wooden broom handle if the supply cannot be turned off.
3. Send someone to call for help, using the emergency numbers.
4. Check whether the person is responsive and breathing normally.
5. If the person is unresponsive and not breathing normally, begin chest compressions at a rate of about 100 to 120 a minute, pushing down about 5 to 6 centimetres in an adult, and continue until help arrives or the person recovers.
6. Treat burns by cooling them under cool running water for at least 20 minutes, then cover loosely with a clean non-stick dressing.

Other common injuries:

• Cuts: Press a clean dressing firmly on the cut to stop bleeding, raise the limb if possible, and bandage it.
• Particle or fibre in the eye: Do not rub the eye; rinse with clean sterile eyewash or running water and seek medical help if the particle remains.
• Falls from a ladder: Do not move the casualty if a neck or back injury is suspected; keep them still and warm, and call for help.
• Burns from tools: Cool the burn under cool running water, and do not apply creams or burst any blisters.

Record every injury, however small, in the site accident book, and replace the supplies used from the kit.

2.1.5.2 Emergency contact

An emergency contact list is a short, printed sheet placed near the telephone and inside the first aid kit and the equipment room door, so that anybody can find the right number quickly. Kenya's national emergency numbers are 999 and 112; the list adds the local numbers that these services do not replace.

• Fire brigade and ambulance: The local numbers for the town and the nearest emergency medical service, in addition to 999 and 112.
• Police: The nearest station, for theft, assault or a threat on site.
• Site contacts: The building manager, security desk and the person named as first aider.
• Utility and technical support: The power supplier's fault line, the internet service provider's support desk and the equipment vendor's support number.
• Own organisation: The supervisor or employer, and the next of kin for the technician where the employer holds this information.
• Keep it current: Check the numbers at the start of each job and update after any change; a wrong number is worse than none.

2.1.5.3 Contingency measures

Contingency measures are the back-up plans that keep people safe and limit damage when something goes wrong during an installation. They are agreed at the start of the job and written down.

• Stop work and make safe: Anyone may stop the job when they see imminent danger; power is isolated and tools put down before moving away.
• Emergency power off: Know where the emergency power-off button and main isolator are, and who may operate them.
• Evacuation: Everyone knows the exit routes and the assembly point, and a person is named to check that all are out.
• Power failure: A UPS keeps critical equipment running long enough to shut down properly, and a generator or an alternate supply takes over where the building has one.
• Back-ups and rollback: Before changing a working network, take a copy of device configurations and note how to return to the old set-up if the new one fails.
• Temporary connectivity: A mobile data router on a different provider can keep essential services online while the main link is down.
• Incident report: After any emergency, record what happened, what was done and what must change.

Chapter Summary

This chapter covered essential safety measures necessary during computer network installation, emphasizing the use of personal protective equipment such as gloves and antistatic devices, proper cable management, electrical safety, and fire preparedness. It then explored the identification of key network components including switches, routers, transmission media, and security devices, alongside the tools and materials required for assembly. The process of setting up a computer network was detailed, highlighting network design, cabling standards, cable termination, and wireless device installation with best practices for cable management. Configuration of network devices was examined through an understanding of network models, IP addressing schemes, and the setup of switches, routers, and wireless access points including security configurations and network privileges. The importance of thorough network documentation was discussed, covering physical, logical, and configuration records. Finally, the chapter addressed the disposal of network components, focusing on e-waste classification, hazards, legal regulations, and appropriate disposal methods to ensure compliance with Kenyan laws and environmental standards.
