Foundry safety is a top concern for all foundries that perform metal casting. There are many health and safety issues to be aware of during the casting process.

The most obvious casting safety hazard is burns. Employees are exposed to extremely hot molten metal. If an employee comes into contact with the material or equipment, they will be seriously injured.

However, burns are not the only issue with casting health and safety. A casting safety program should also address issues such as dust inhalation, heat stress, and vision protection.

When exploring ways to improve casting safety, we recommend that organizations:

1. Complete a Thorough Risk Assessment

A comprehensive hazard assessment will help identify all health and safety issues in the casting process. While nearly all foundries will encounter some of the same casting safety issues, each operation is unique. Therefore, this assessment helps the plant determine which issues pose the greatest risk to its organization.

2. Have Workers Wear Proper Safety Equipment and Clothing

The dangers of many health and safety issues in the casting process can be mitigated by wearing proper safety equipment during work hours. Proper clothing and equipment can reduce the risk of employees being burned, inhaling dust, or suffering eye injuries.

3. Comply with Environmental Regulations

Discussions about safety precautions in foundries and investment castings often revolve around the health and wellness of employees. While keeping employees safe is always a top priority, complying with environmental regulations is equally important.

Foundries have a duty to be good stewards of environmental resources. Therefore, complying with regulations will minimize the foundry's impact on the environment while reducing the risk of large civil penalties.

4. Watch out for heat stress

Hot environments like those in foundries can be harmful to employees. Aside from burns, the biggest heat-related risks to employees are heat stress, heat exhaustion, and heat stroke.

Employees should be trained to recognize the signs of heat stress so they can take care of each other, notify management, and provide basic first aid.

5. Keep it dry

When moisture enters a foundry, it can create explosive vapors that can burn employees. Therefore, facility managers must make every effort to minimize moisture on the foundry floor. This can be accomplished by heating ingots before melting them and storing sand in a moisture-proof area.

6. Inspect machinery before use

All equipment should be thoroughly inspected before use. This inspection will ensure that the equipment is functioning properly and is not damaged.

Inspecting machinery also allows facility managers to identify potential problems early. This, in turn, will extend the life of the equipment, prevent casting defects, and reduce the likelihood of encountering unexpected production delays.

7. Provide ongoing training

Over time, employees may become complacent about health and safety issues when casting. Fortunately, employers can reduce this complacency by providing regular training to their employees. At a minimum, employers should provide safety training annually.

8. Prevent and Reduce Harmful Vibration

Investing in equipment that produces minimal vibration can significantly improve safety in several ways

First, reducing vibration minimizes equipment damage, which reduces the risk of catastrophic mechanical failure. Reducing vibration can also improve employee communication, which brings us to the next casting safety consideration—noise.

9. Monitor Noise Levels

High noise levels in an industrial foundry environment can create a number of health and safety issues during the casting process. Excessive noise can damage employee hearing. Additionally, excessive noise pollution makes it difficult for employees to communicate. They will not be able to collaborate effectively and may have a hard time warning each other of hazards.

Therefore, facility managers should monitor noise levels within the foundry. Additionally, whenever possible, they should invest in noise reduction equipment because doing so can improve safety and make it easier for employees to communicate.

10. Reduce the risk of dust exposure

Inhaling dust poses a variety of health risks to employees. Foundries can reduce these risks by proactively reducing the dust generated and installing quality ventilation equipment. Employees should also be provided with personal protective equipment (PPE), such as respirators.

Collectively, these strategies will help foundries address many health and safety issues in the casting process.
