Are Machine Manufacturers Required to Provide Complete Guarding Systems on New Equipment to Meet OSHA Safety Standards?

Machine manufacturers are not explicitly required by OSHA to provide complete guarding systems on new machines, but the equipment must be capable of being operated safely once installed. In the U.S., OSHA holds the employer (end user) responsible for ensuring machines are properly guarded before use, under 29 CFR 1910.212(a)(1).

That said, reputable manufacturers often follow ANSI B11 and ISO 12100 standards, which include recommendations for safeguarding during design. Many provide integrated or optional guarding systems—but full compliance may still require site-specific guarding adjustments after installation.

Key Points:

• OSHA requires employers to ensure all hazardous machine parts are guarded.

• Manufacturers are encouraged (but not mandated) to follow ANSI/ISO safety design standards.

• Employers should conduct a machine guarding assessment after installation to confirm site-specific risks are addressed.

Summary:
While manufacturers often provide guarding, it is ultimately the employer’s responsibility to ensure machines meet OSHA-compliant safety standards once installed and in use.
