Additionally, it’s important to keep combustible materials away from any open flames or heated metals.

  • Lockout/Tagout Procedures

    The lockout/tagout procedure is an important part of any safety program in the metal casting industry. This procedure involves locking out or tagging out all energy sources before performing maintenance or repairs on equipment.

    By doing this, it ensures that no one will accidentally come into contact with live electricity while repairs are being performed. This procedure should always be followed whenever maintenance or repairs are needed on any type of equipment used in the metal casting process.

  • Engineering Controls

    Engineering controls involve designing your workspace in such a way that it minimizes exposure for workers and keeps them safe from hazards associated with the creation of highly engineered castings and hot metals.

    This includes installing proper ventilation systems to dissipate heat, using special ovens or furnaces that are designed to reduce heat exposure, and installing proper shielding on machines or tools with higher chances of exposure to scathing temperatures during operation.

    Another aspect of engineering controls is providing workers with proper training regarding how to handle hazardous materials safely as well as how to use the necessary protective equipment correctly while performing their tasks.

    The most important safety measure is always following instructions provided by your supervisor or company policies when handling any type of hot metal – no matter what type of task you are performing.

  • Ergonomic Design Of Workstations

    Ergonomics plays an important role in the design of workstations used for metal casting processes. Ergonomically designed workstations provide comfort for operators while reducing fatigue and strain on their bodies which can lead to injuries or illnesses over time if not addressed properly.

Case Studies

There have been numerous cases in the past involving disabling and non-disabling accidents in the metal casting industry as well as foundries. The constantly changing specifications from product to product make it impossible to standardize operations and workers are required to be fewer specialists and be more versatile with various types of foundry operations.

While molding and demolding are average on the scale of possible metal casting accidents, melting metal, cleaning, chipping, and finishing are the most hazardous elements of the process that pose a higher range of accidents among metal casting workers.

Practically, almost all workers are subject to certain hazards despite their operation on the work floor. Every worker faces the risk of getting their toes or fingers crushed while moving heavy materials with more chances of sprains. When in the vicinity of pouring molten metal into molds, the possibility of getting burnt by metal splashes is common.

Piled materials and the shifting of materials overhead via cranes and lifts are other possible dangers lurking around the corners.

  • Defective Equipment
    In one injury case, defective casting equipment was at the core of the issue resulting in the death of one worker and causing second and third-degree burns to three others. Four workers were involved in the metal pouring process when the casting die filled with the molten metal ruptured, throwing the liquid metal on the workers. The equipment lacked proper safety guards and was poorly designed concerning other safety features.
  • Occupational Hazard
    In a more unsettling incident, the monitoring equipment of a facility malfunctioned, after which a breakdown team was dispatched to the spot to undertake repairs. However, the efforts were uncoordinated with the operational management and resulted in more serious predicaments.

    While hazardous gasses started escaping the facility, a team of firefighters was sent in to rectify the situation without any clue of the concentration of the gasses. This series of errors, both manual and mechanical, resulted in the death of three people and serious gas poisoning of various degrees for 22 other people involved.

    In studies targeting such metal casting accidents, statistics reveal that simply having immediate medical attention on site drastically reduces the overall rate of injuries and serious health issues. And while in most cases the workers are blamed for such mishaps, oftentimes, defective equipment and errors like unplanned coordination, communication, and lack of situational awareness results in equally life-threatening accidents.

Final Thoughts On The Risks Of Metal Casting
