Machine Guarding Safety Standards

Safety Standards

WireCrafters wire partition systems (fixed & movable guards) meet or exceed the requirements of the following standards in regards to guarding when installed in accordance with the risk assessment (SRS – Safety Requirements Specification), and the manufacturers, WireCrafters, installation instructions.

OSHA 1910.212 – Machinery and Machine Guarding

OSHA 29 CFR 1910.212 is the General Requirements for All Machines standard, which mandates that employers provide guards and safety devices to protect employees from hazards like nip points, rotating parts, and flying chips on any power-driven machinery. Employers must ensure guards are affixed and secure, designed to prevent new hazards, and allow for safe operation and maintenance. Employees also need to be trained on the safe operation of machinery and the hazards it presents.

ANSI B11.19-2019

Performance Requirements for Risk Reduction Measures: Safeguarding and other Means of Reducing Risk
This standard provides performance requirements for the design, construction, installation, operation, and maintenance of the risk reduction measures listed below when applied to machines -inherently safe by design (see clause 7); engineering controls – guards (see clause 8); engineering controls – control functions (see clause 9); engineering controls – devices (see clause 10); administrative controls (see clause 11).

ANSI B11.0-2020

Safety of Machinery
This type-A standard applies to new, existing, modified or rebuilt power driven machines, not portable by hand while working, that are used to process materials by cutting; forming; pressure; electrical, thermal or optical techniques; lamination; or a combination of these processes. This includes associated equipment used to transfer material or tooling, including fixtures, to assemble/disassemble, and to inspect or test. The associated equipment, including logic controller(s) and associated software or logic together with the machine actuators and sensors, are considered a part of the industrial machinery. Contains B11.TR3 in its entirety.

ISO 14120:2015 – Safety of Machinery

ISO 14120:2015 specifies general requirements for the design, construction, and selection of guards provided to protect persons from mechanical hazards.

ISO 14120:2015 indicates other hazards that can influence the design and construction of guards.

ISO 14120:2015 applies to guards for machinery which will be manufactured after it is published.

The requirements are applicable if fixed and movable guards are used. This International Standard does not cover interlocking devices. These are covered in ISO 14119.

ISO 14119:2013 – Interlocking Guard Design

Safety of machinery – Interlocking devices associated with guards – Principles for design and selection

ISO 14119:2013 specifies principles for the design and selection ? independent of the nature of the energy source ? of interlocking devices associated with guards.It covers the parts of guards which actuate interlocking devices. It does not necessarily provide all the specific requirements for trapped key systems.

ISO 14119:2013 provides measures to minimize defeat of interlocking devices in a reasonably foreseeable manner.

ISO 13855:2010 & ISO 13857:2019 – Safe Distances

ISO 13855:2010
Safety of machinery – Positioning of safeguards with respect to the approach speeds of parts of the human body

ISO 13855:2010 establishes the positioning of safeguards with respect to the approach speeds of parts of the human body.

It specifies parameters based on values for approach speeds of parts of the human body and provides a methodology to determine the minimum distances to a hazard zone from the detection zone or from actuating devices of safeguards.

The values for approach speeds (walking speed and upper limb movement) in ISO 13855:2010 are time tested and proven in practical experience. ISO 13855:2010 gives guidance for typical approaches. Other types of approach, for example running, jumping or falling, are not considered in ISO 13855:2010.

Safeguards considered in ISO 13855:2010 include:

– electro-sensitive protective equipment, including light curtains and light grids (AOPDs), and laser scanners (AOPDDRs) and two-dimensional vision systems;

– pressure-sensitive protective equipment, especially pressure-sensitive mats;

– two-hand control devices;

– interlocking guards without guard locking.

ISO 13857:2019
This document establishes values for safety distances in both industrial and non-industrial environments to prevent machinery hazard zones being reached. The safety distances are appropriate for protective structures. It also gives information about distances to impede free access by the lower limbs (see Annex B).

This document covers people of 14 years and older (the 5th percentile stature of 14-year-olds is approximately 1 400 mm). In addition, for upper limbs only, it provides information for children older than 3 years (5th percentile stature of 3-year-olds is approximately 900 mm) where reaching through openings needs to be addressed.

RIA TR 15.406 (2014/2016)

Safeguarding
TR 406 explains how to design a system of safeguards to protect human workers in an industrial environment that also contains robot system(s). This document contains greater detail than in the original 2012 R15.06 standard document. The TR 406 document as published in 2014 continues to be the current active version.
