4.5: Environmental Impacts and Local Environmental Controls

MSDS/SDS

Safety sheet describing hazards/handling for chemicals (batteries, CRTs, solvents, toner).

Where to find MSDS info

Product/company, ingredients, hazards, first aid, firefighting, spill response, handling/storage, more.

Disposal procedures

Follow MSDS/SDS and local/OSHA rules; use approved e-waste/hazmat channels.

Battery disposal

Treat UPS and device batteries as hazardous; take to approved facility—don’t trash.

Toner/ink disposal

Recycle/return cartridges (vendor box/programs); avoid general waste.

Other device disposal

Check MSDS/SDS and org policy before discarding any IT asset.

Room temperature control

Keep equipment in a cooled space; avoid hot closets.

Room humidity control

Target ~50%; high = condensation, low = ESD risk.

Proper ventilation

Ensure airflow around systems; prevent heat buildup.

UPS purpose

Provides short-term power during outages, brownouts, and surges.

UPS types

Standby (basic), Line-interactive (voltage regulation), Online (double-conversion).

UPS features

Auto-shutdown support, adequate VA/W capacity, enough outlets, surge/phone/data protection.

Surge suppressor role

Diverts spikes to ground and filters line noise.

Joule rating (suppressor)

Energy it can absorb; higher is better—>600J recommended.

Surge amp rating

Max surge current it can handle; higher is better.

UL 1449 let-through

Voltage allowed past the suppressor (330/400/500V); lower is better.
