Keep fire exits clear: in case

of fires, exits should be clearly

marked and accessible. Fire

Drill practices are a necessity.

Adequate clothing: baggy

clothing, bracelets and

necklaces should be avoided as

these might get caught up in

equipment. Long hair should be

tied back and protective

clothing should be worn.

Risks involved when

replacing/installing/upgrading hardware

components

1. Electrostatic discharge

2. Physical damage to equipment

3. Negative impact on data

4. Human injury

Electrostatic Discharge - when static

electricity that has built up on you is

released (discharged) through a component.

The discharge could cause damage to the

component by burning out some of the very

tiny and sensitive circuits.

Precautions against electrostatic discharge:

use anti-static equipment including

anti-static wristband

anti-static mat

anti-static bags

Precautions against physical damage:

apply appropriate force

use the right tools (including cleaning, ESD equipment and hand tools)

keep magnets away

handle components with care and do not leave them towards the edge of the workspace

make sure that components are properly fixed in place without being loose

Negative impact on data (Data Loss) - when a component, such

as a hard disk, is formatted or broken such that the data cannot

be found or used any longer.

Negative impact on data (Data Corruption) - when data

becomes altered or spoiled. Corrupted data is usually still

present on the system, but is no longer trustworthy or usable.

Data can become corrupted when it is copied from one

storage medium to another.
