In a foundry, the molten metal is cast into a mould. This task is carried out either using a static (manual) casting procedure or using continuous spin or spray casting procedures. There are risks associated with the casting process of any metal alloy:
- The danger of explosion and burn injuries from hot materials
- Exposure to gases/vapors/fumes/dusts can cause respiratory problems
- Dermatological conditions resulting from corrosive solutions or chemicals
- Ocular damage caused by dust, metal fragments, light radiation, chemical splashes
- Working in a hot environment can cause heat stress, heat stroke or fatigue
- Injuries resulting from working with heavy equipment or from other accidents
Therefore, it is essential to learn about the safety practices for a foundry irrespective of the nature of the casting services.
- Wearing Proper PPE
The workers have to wear the correct clothing and accessories when working at a sand casting foundry.
- The clothes made of synthetics are easily combustible. Thus, it is essential to wear heavy cotton, leather, or heavy wool clothes. They can protect the skin from hot gases and dust.
- Footwear has to be suitable for industrial work environments.
- No skin is supposed to remain exposed after wearing the clothes or accessories.
- It is essential to wear properly built face shields and safety glasses to reduce the risk of injury to the face or eye.
- Using Clean Material
The molten metal releases harmful fume in a sand casting foundry. Therefore, it is essential to ensure that the metal does not contain a large volume of impurities, increasing the risk of exposure to harmful elements.
- Know the Metal
The alloy elements, such as zinc, mercury, lead or beryllium, can be dangerous if the casting is performed without protection. It enables the workers to learn about the health risks of handling these elements during casting and lets them take adequate protection.
- Preliminary Inspection
A defective machine at the foundry may cause fatal accidents. Therefore, it is important to regularly inspect the condition of the machines (burners, furnace walls, fuel lines and pouring equipment) used in a sand casting company before starting the work.
- Informing & Training the Staff Regarding Actions during Emergency
It is essential to keep the workers of a stainless steel casting company or any other casting business informed regarding emergencies, such as defective pouring hardware, metal leakage resulting from flask failure or defective crucible.
The workers remain prepared to handle emergencies and have evacuation plans when they are well informed.
- Furnace Inspection before Metal Casting
Inspecting the furnace before starting the stainless-steel, brass, bronze, copper or lead-free casting is crucial. An explosion may result from moisture or water under the surface of liquid metal.
- Beware of Leakage
The leakage of gas or metal in the brass & bronze casting business or any other type of sand casting business can be dangerous. The workers may inhale the toxic fume, and the hot metal may cause injuries.
- First-Aid & Dry Sand
It is essential to have a first-aid box for bronze, stainless steel, lead-free, or copper alloy casting at any foundry. It is equally important to have dry sand. It can be used to extinguish the fire until firefighters' arrival or control the metal spills.
