HAZard IDentification (HAZID)

Environment Hazards: Seismic event (earthquake, Tsunami), Climate extreme (temperatures, wind, hurricane, flood, fog, sand storm), lightning, ground slide etc.

Human hazards: Adjacent industrial facility, transport corridor, adjacent land use/human activities, etc.

Process hazards: Release of flammable gas/liquid, toxic gas, uncontrolled reaction, ignition sources,

Facility hazards: Storage (combustible, flammable, corrosive, pollutants), maintenance operations, structural failure, confined spaces,

Working hazards: Carcinogenic chemicals, radioactive materials,
