Molten metal splashed onto a worker will stick to exposed skin and some fabrics, causing them to instantly ignite, leading to severe burns or death.
Working in the primary and remelt metal industries can be a hazardous occupation. The making and shaping of iron, steel, aluminium and other metals involves heat, pressure, the movement of molten metals and other activities that can expose workers to numerous physical and chemical hazards. Heat, noise, radiation, vibration, airborne particles, space restrictions, hazards from falling objects, electrical shock and molten metal are just a few examples of hazards that workers may be exposed to.
Heat stress illnesses such as heatstroke are a common hazard, primarily due to infrared radiation from furnaces and molten metal. This is especially a problem when strenuous work must be done in hot environments. When heatstroke occurs, the body temperature can rise to 41°C (106°F) or higher within 10 to 15 minutes. Heatstroke can cause permanent disability or death if the worker does not receive emergency treatment.
Hot Metal Industry Hazards: molten substance splash, radiant heat and flame sources are possible.
Failure to use proper PPE in smelting and casting environments can be dangerous. For example, molten aluminium is typically handled at 700°C to 780°C (1300°F to 1450°F), which creates a serious fire hazard and can cause severe burns should a worker come in contact with the melt. Furthermore, mixing water or other contaminants with molten aluminium can cause explosions that range widely in violence and can result in injury and death as well as destruction of equipment and plant facilities.
