This document provides a hazard identification and risk assessment for welding work being conducted at a project site in Versova, Mumbai. It identifies several hazards associated with welding including electric shock, fire, health issues from fumes and sparks, and improper use of equipment. For each hazard, it evaluates the severity and likelihood of risks. It also identifies applicable legal requirements and provides control measures to reduce risks. Controls include inspection of equipment, use of protective gear like face shields, isolating work areas, training workers, and ensuring only authorized personnel conduct welding. The overall risk level is determined to be "acceptable and non-significant" when proper controls are implemented.
