Machine Risk Assessment Standards

Machine Risk Assessment and Safeguarding Standards provide basic guidelines for the assessment and reduction of machine-related risk in the workplace. Safeguarding principles outline methods for optimal risk prevention through the recommendation of specific design safety practices and machine ergonomics standards. These include guidance for the proper design, manufacture, integration, and installation of machinery. By adhering to these standards, potential risks to the health and safety of employees working in close proximity with said machinery can be mitigated. This process is aided by guidelines for the evaluation and analysis of radiation and other hazardous substances emitted by machinery. Further, the included packages assess various techniques for risk management, the specification of essential tools and methods of estimation, evaluation, and, most importantly, the careful and methodical reduction of risks associated with machinery. The implementation of the machine risk assessment and safeguarding standards presented here is a vital part of efforts promoting safe practices when using any kind of machinery.

Principles of Risk Assessment

Risk Assessment standards address the multifaceted methodology at the core of risk assessment and risk management programs. They outline the basic terminology, principles, and guidelines for the implementation of risk assessment practices intended to enhance safety in the workplace. Procedures for the identification of hazards, the estimation and evaluation of risk, and the substantial reduction of said risks are expounded upon in great detail. An understanding of and coherent approach to risk assessment is vital to the curtailment of risks associated with machinery.

Health Risk Reduction Standards

Health Risk Reduction standards are focused on an exposition of numerous principles for the control of various risks to the health of personnel interacting with machinery. Assessing the diverse health risks, the standards detail the identification, measurement, and evaluation of radiation and airborne hazards emitted by machinery, risks associated with repetitive handling at high frequency, manual interaction, and more. Through specifications of ergonomic movements and postures for workers, proper design techniques that reduce hazardous emissions, and the application of efficient safeguards against risk-inducing practices, health risk reduction standards are essential to lowering the overall level of health risk.

Design Safety Guidelines

Design Safety Guidelines, integrated into the principles of design for machinery, are a crucial part of the reduction of risks. Safety improvements can be achieved through the use of specific design and manufacturing techniques, followed by validation through extensive analysis and testing. These standards delineate guidelines for manufacture, remanufacture, installation, and rebuilding of robots as well as safety-related parts of control systems in other machinery. Furthermore, descriptions of the design and installation principles for emergency stops are provided.

Safeguarding Practices

Standards for Safeguarding Practices employ the previously presented risk assessment methods in identifying prime practices for the safeguarding of machinery. The selection of specific guards, as well as processes for their construction, installation, operation, and maintenance of these, are introduced. The proper manufacture and testing of all protective devices is imperative to the protection of workers and the safeguarding of machinery.

Machine Ergonomics

Machine Ergonomics standards provide a methodology for the application of ergonomics standard considerations in the design and implementation of machinery with the goal of risk reduction and safeguarding. Through analysis of the interaction between operators and machinery when installing, operating, adjusting, maintaining, repairing, or transporting equipment, safety techniques have been carefully reviewed and enhanced, thus minimizing risk for those who adhere to them. Included in the ergonomic design standards are exact dimensions for access openings into machines, specifications of requirements for human body measurement gathered from anthropomorphic data, application of control actuators, and much more.
