Scenario: You work in a manufacturing facility where welding and metal cutting are common practices. You need to select appropriate FRC for your team.
Task: 1. Identify the specific hazards present in your scenario. 2. Research and choose a type of FRC that would best protect your team from those hazards. 3. Explain your reasoning, highlighting the key features of the chosen FRC that address the specific risks. 4. Mention any additional safety measures or training that might be necessary.
**Hazards:** * **Heat and flames:** Welding and cutting generate intense heat and sparks. * **Molten metal:** There is a risk of molten metal splashing. * **UV radiation:** Welding arcs produce harmful UV radiation. **Appropriate FRC:** * **Flame-Resistant Clothing:** Specifically designed for welding and metalworking. * **Arc Flash Suits:** Optional, but recommended if the risk of electrical hazards exists. **Reasoning:** * **Flame Resistance:** The FRC should resist ignition and prevent flames from spreading, protecting against burns from sparks and heat. * **Heat Resistance:** The material should withstand high temperatures to prevent heat transfer to the wearer. * **Molten Metal Resistance:** Some FRC is specifically designed to resist splashes of molten metal. * **UV Protection:** Look for FRC with built-in UV protection to prevent damage to the skin. **Additional Safety Measures:** * **Proper training:** Workers should receive thorough training on the use and limitations of FRC. * **Regular inspections:** Ensure that FRC is regularly inspected and maintained for damage. * **PPE:** Ensure workers use other essential PPE such as welding helmets, gloves, and boots.
