Who governs machine safety in the United States?

Why is it necessary to conduct a risk assessment?

Occupational Safety and Health Act (OSHA)

OSHA is the primary federal law which governs occupational health and safety in the private sector and federal government in the United States. It was enacted by Congress in 1970 and was signed by President Richard Nixon on December 29, 1970. Its main goal is to ensure that employers provide employees with an environment free from recognized hazards, such as exposure to toxic chemicals, excessive noise levels, mechanical dangers, heat or cold stress, or unsanitary conditions.

American National Standards Institute (ANSI)

ANSI is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide.

Manufacturing Services & Installation, LLC, follows both OSHA laws and ANSI standards when conducting risk assessments, and when quoting machine safety and guarding concepts. The particular law, or standard, for each hazard or deficiency found is listed while conducting the risk assessment.

Risk Assessment Process

An evaluation has to always take into account the machine’s intended use, the ambient conditions, the followed principles of safe design, safeguarding, complementary safety measures and information for use.

On-site Survey 

The risk assessment process will include an initial on-site survey to determine the scope of the project, and a meeting to determine the objectives of the company and the number and types of machines to be included in the risk assessment.

On-site Machine Risk Assessment 

During the risk assessment process, the process of interaction with the following plant personnel is necessary to conduct the risk assessment: machine operators, maintenance personnel, and a plant electrical engineer.

The risk assessment follows the ANSI B11.TR3 guidelines, other applicable ANSI guidelines and OSHA requirements. If the company has a safety standard that supersedes this, it can be implemented into the report. All photographs and information needed to generate guarding concepts and risk assessments are gathered in this step. The company must furnish machine electrical schematics, motor sizes, and pneumatic/hydraulic prints.


The on-site survey and risk assessment will produce the following reports:

  1. Machine Risk Assessment. The ANSI B11.TR3 machine risk assessment will be completed showing the OSHA standards and ANSI guidelines that apply to each guarding element required.
  2. A photographic log will be provided, showing where guards must be added and why.
  3. Guarding quotation. Once the guarding concepts are approved by the company, a firm quotation will be provided to implement the necessary guarding.

*The company will receive a hard copy of the risk assessment report for all machines assessed.

Machine Guarding & Safety Solutions

The level of protection from machine hazards has to be built according to the remaining risk from the machinery equipment.
The calculations are based on the following three parameters:

  • Seriousness of injury
  • Frequency and/or duration of exposure to the hazard
  • Possibility of avoidance of the hazard

*Machines have to be designed in a way that all dangerous areas, processes and important machine functions are able to be observed from a control panel position. *An additional risk evaluation is necessary upon completion of machine guarding to determine any residual risk to the operator and company personnel.

Guarding can be bypassed or removed to run the machine in an unafe manner.


Custom interlocked hinged guarding prevents bypassing the safety system, or removing the guarding to run the machine.
Our safety control determines when it is safe for personnel to enter the hazardous arrea.


Rotating parts and pinch points expose operator to hazards.


Custom interlocked guarding allows operators to load and unload parts with guards in place.
The part loading mechanism was re-engineered to work with the guarding. This unique guarding method slides out of the way for batch set up.
The guarding is also designed to contain the grinding wheels in case of disintegration.

Rotating, chemical and pinch point hazards are present on the non-operator side of machine.


Custom interlocked guarding method allows for finished parts to exit the machine while protecting personnel.


End User required the custom safety control to be mobile so the entire machine could be moved for wash down.


Custom safety controller using a safety PLC.

Manufacturing Services & Installation, LLC, is a full service safety integrator
for risk assessments, machine guarding and safety controls.
