Fatal incident highlights machine safety gaps
In a devastating incident in July 2024, a 58-year-old supervisor tragically lost his life while working on a door molding machine in Alabama. The employee was servicing the equipment when he became entrapped, suffering fatal head injuries.
Unfortunately, this tragedy highlights the importance of the employer’s responsibility to not only have safety programs are in place, but also ensuring workers are effectively trained and properly follow the safety processes and procedures.
Investigation results
OSHA's investigation revealed that critical safety procedures were not followed for machine safety. The company was cited for one willful violation for not de-energizing a machine and two serious violations for allowing employees to bypass safety doors and failing to conduct annual inspections on energy control procedures. These violations have resulted in $193,585 in proposed penalties. Unfortunately, this isn't the first time the company has faced safety issues; there have been previous fatalities and a history of violations since 2016.
So, what can an employer do to ensure this does not happen to them? OSHA provides two comprehensive standards related to machine safety that employers need to establish in their safety programs. The first is machine guarding, found at 1910 Subpart O - Machinery and Machine Guarding. The second is 1910.147, The Control of Hazardous Energy (Lockout/Tagout).
Importance of machine guarding
The machine guarding standard requires that machines be equipped with guards to protect operators and other employees from hazards such as point of operation, ingoing nip points, rotating parts, and flying debris. These guards must be securely attached to the machine and designed to prevent any part of an employee's body from entering the danger zone during operation.
OSHA doesn't specifically require machine guarding training, but it does expect employers to make sure their workers are protected from machine hazards. This means employers need to train their employees on how to recognize these hazards and use machine guards correctly. As a best practice, training should occur prior to working on the equipment, and whenever changes in the equipment or processes occur that impact the guarding.
Importance of controlling potentially hazardous energy
Lockout/Tagout (LOTO) requirements are designed to protect workers from hazardous energy during the servicing and maintenance of machines and equipment. The standard applies to the control of energy during these activities, where unexpected energization or the release of stored energy could cause injury.
As part of this regulation, employers must establish an energy control program that includes specific procedures for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy. The regulation also requires evaluating the procedures at least annually to ensure they are accurate and effective.
Employee training is dependent on the role of the employees including:
- Authorized employees, who perform the lockout/tagout procedures, must be trained in recognizing hazardous energy sources and the methods to isolate and control them.
- Affected employees, who operate or use the machines being serviced, need to be aware of the procedures and the importance of not attempting to restart equipment that has been locked or tagged out.
- Other employees, who may be in the area, should be informed about the lockout/tagout procedures and the significance of the devices used.
Key to remember: This tragic incident highlights the urgent need for employers to enforce safety when working with machines, including machine guarding and lockout/tagout procedures, and ensure employees are well-trained to recognize and mitigate hazards.
