A walk-through survey of work areas for the purpose of identifying sources of hazards to faculty, staff, or students. Basic categories that should be considered include but are not limited to: impact from flying objects, moving machinery or falling objects; penetration from sharp objects that can pierce the feet or cut hands; compression (roll-over of loads or heavy materials); exposure to harmful dust or chemicals; exposure to high heat or temperature extremes; exposure to light (optical) radiation from welding operations or work with lasers and electrical hazards; and exposure to noise.
