Scenario:
You are a supervisor overseeing a team of welders working on a construction site. The site is located near a large storage area filled with flammable materials.
Task:
**1. Safety Measures:** * **Hot Work Permit:** A permit must be obtained, outlining the specific procedures and safety measures. * **Clearance Zones:** Establish a wide clearance zone around the welding area, free of flammable materials. * **Fire Barriers:** Utilize fire-resistant barriers or screens to isolate the welding area from the storage area. * **Fire Suppression:** Ensure readily accessible fire extinguishers rated for the type of fire hazard (e.g., Class B for flammable liquids). Consider sprinkler systems or other fire suppression systems if applicable. * **Ventilation:** Provide adequate ventilation to remove any flammable fumes or gases generated during welding. * **PPE:** Ensure all welders wear appropriate PPE, including flame-resistant clothing, gloves, eye protection, and respiratory protection. **2. Roles and Responsibilities:** * **Fire Watch:** * Constant monitoring of the welding area for sparks or embers. * Immediate response to any potential fire hazards. * Responsible for using fire extinguishers if necessary. * **Welders:** * Adhering to all safety procedures outlined in the permit. * Wearing appropriate PPE at all times. * Maintaining awareness of surroundings and potential hazards. * Reporting any unsafe conditions to the supervisor or fire watch. **3. Post-Operation Inspection:** * **Thorough inspection:** Ensure all welding areas are free of smoldering embers, sparks, or hot metal. * **Check for damage:** Inspect the surrounding area for signs of damage or potential hazards caused by the welding operation. * **Remove flammable materials:** Ensure any flammable materials used during welding are properly stored or disposed of. * **Documentation:** Document the post-operation inspection and report any findings to the supervisor.
