– Compliance with governmental disposal
regulations.
» Electronic equipment is not composed of environmentally
friendly materials.
• Items like CRT monitors and motherboards have some
dangerous materials that can leach into the environment.
» Always follow federal, state, and local disposal guidelines.
» Always follow corporate disposal guidelines.
– Material Safety Data Sheet (MSDS).
» Contains safety information on materials found in the
workplace.
• Known health issues associated with the material.
• Physical properties of the material (e.g., the flash point and
toxicity of the material).
• Proper disposal methods for the material.
• Steps to take if exposure occurs.
» Each workplace will have its own set of MSDSs.
• Know where they are kept and know the common hazards.

– Power issues.
» Power surge: an upward spike in electrical current.
• Can severely damage sensitive components before circuit
breakers can engage.
• Can be caused by anomalies in the power grid, lightning
strikes, and by power being returned after a blackout.
» Brownout: a sag downward in electrical current.
• Can severely damage sensitive components as they strain to
draw current that is not present.
• The most common cause is overloaded circuits, either within
the building level or at the power grid level.
» Blackout: the sudden loss of all power.
– Power issue control.
» The surge suppressor: it protects against spikes in power only.
» The battery backup: it protects against spikes, brownouts, and
mitigates against blackouts.
• Works by taking wall current and delivering it to a battery or
set of batteries, which both store and condition the power
before delivering it to its destination.

– Heat and humidity.
» Heat is an enemy of electrical components.
• High heat can cause the burn out of sensitive components.
» Humidity can also become an environmental factor.
• If humidity is too low (beginning at 60%), electrostatic
discharge (ESD) becomes a danger.
– Heat and humidity mitigation.
» Poor airflow allows heat to build up, so good ventilation is of
primary importance.
• Ensure that there is adequate space around equipment.
• In dusty environments, use additional filters and enclosures.
• Remove dust and debris from the inside of cases on a regular
basis. Compressed air and specialty vacuums can be used.
» Use proper component handling techniques to protect against
ESD.
• Always wear an ESD strap when working on systems.
• Practice self grounding.
• Use antistatic bags when transporting sensitive components.

Environmental impact and control.
Always follow federal, state, and local regulations and guidelines for the
proper disposal of electronic equipment. Many of the materials that make
up electronic components are not environmentally friendly or healthy for a
person to be exposed to. MSDSs can be used to find out the health dangers
posed by materials and how they can be safely handled and disposed of.

Your impact on the
environment.
Summary
Environmental power issues include surges, brownouts, and blackouts.
Surge protectors can protect against spikes in power, but not against
brownouts or blackouts. Battery backup systems can protect against all
three. Heat and humidity can also have an impact. Heat can cause
electronics to burn out; the key mitigation is to ensure that there is adequate
airflow. The risk of ESD increases as humidity decreases, but the risk can
be alleviated by using proper component handling techniques.
