Cal/OSHA Cites Ceramics Co in Fatal Machine Guarding Accident

Santa Ana—Cal/OSHA has issued more than $250,000 in citations to Aardvark Clay & Supplies, Inc. for its willful failure to properly guard equipment after an employee was fatally entangled in a clay manufacturing machine called a pug mill.

Safety guards had been removed from the industrial mixer and the worker had not received training on the machine before the accident.

The Santa Ana company uses industrial pug mills to manufacture and mix clay. On September 20, 2018, an employee became caught in the unguarded mixing blades of the machine when he tried to identify why the clay stopped traveling through the extruder. 

Cal/OSHA’s investigation found that all four of the shop’s pug mills had unguarded openings exposing employees to the moving parts. Safety regulations require mixers to have a cover to prevent employees’ hands from entering the machine during operation. 

Aardvark Clay & Supplies also failed to effectively train workers on the hazards involved with operating the machinery and did not identify or correct the hazards. Although the manufacturer had provided safety guards for the machinery, the employer removed the guards.

At one point, fabricated guards were added to the machines but were later removed when the employer believed they interfered with the rate of production.

Cal/OSHA cited the company $250,160 in proposed penalties for five violations, classifying one as willful-serious accident-related, one willful-serious, two serious and one general. The willful-serious violations were cited for the employer’s failure to guard machine openings and points of operation.

The serious violations identify hazards from the unguarded cutting portion of the clay machine and failure of the employer’s safety program to identify unsafe conditions, implement corrective procedures and effectively train employees on work-related hazards. 

From 2013 to 2017, contact with objects or equipment was among the leading causes of fatal occupational injuries in California. To avoid accidents and fatalities, employers can get free assistance from Cal/OSHA’s Consultation Services to ensure machines are properly guarded.
