The worker is handling dry ice with bare hands, which can cause cold burns or frostbite due to the extreme temperature of dry ice (-78.5°C / -109.3°F). His facial expression also suggests he is in pain or discomfort—likely from skin contact with the substance. This indicates unsafe handling of a hazardous material. Always use insulated gloves or tongs when handling dry ice to prevent skin injury. Work in well-ventilated areas to avoid dangerous CO₂ buildup. Dry ice is safe to use only when proper protective equipment and procedures are followed. Stay safe—protect your hands and your health.
