Overview
ISO 20474-8:2017, titled Earth-moving machinery - Safety - Part 8: Requirements for graders, is an essential international standard published by ISO. It specifies the safety requirements uniquely applicable to graders, a type of earth-moving machinery defined in ISO 6165. This document complements the general safety requirements outlined in ISO 20474-1 and takes precedence where specific grader provisions differ.
The standard addresses all significant hazards and hazardous situations related to graders during commissioning, operation, and maintenance phases. It sets forth technical measures to eliminate or reduce risks, ensuring safer use consistent with manufacturer’s intended application and foreseeable misuse. ISO 20474-8:2017 applies to graders manufactured after its publication and supports manufacturers, operators, and safety professionals in achieving compliance with accepted safety practices.
Key Topics
ISO 20474-8:2017 covers a comprehensive range of safety aspects tailored for graders, including but not limited to:
Applications
ISO 20474-8:2017 serves various practical applications across industries relying on graders, including construction, road maintenance, earthworks, and infrastructure projects. Its implementation:
- Helps manufacturers design and produce graders that meet global safety benchmarks.
- Assists equipment operators in understanding critical safety features and operating procedures to mitigate hazards.
- Enables safety auditors and regulatory bodies to assess grader compliance with international safety standards.
- Supports maintenance teams in applying correct safety measures during servicing and inspections, reducing accident risks.
By adhering to this standard, organizations can reduce injuries, prevent costly downtime, and enhance overall operational safety in earth-moving operations involving graders.
Related Standards
ISO 20474-8:2017 is part of the broader ISO 20474 series, which covers safety requirements for various earth-moving machinery types. Key related standards include:
- ISO 20474-1:2017 – General safety requirements applicable to multiple earth-moving machinery families; serves as a foundation alongside Part 8 for graders.
- ISO 6165 – Defines basic types and terminology of earth-moving machinery, including grader definitions relevant to ISO 20474-8.
- ISO 7134 – Terminology and commercial specifications specific to graders.
- ISO 12100 – General principles for machinery safety design, risk assessment, and risk reduction principles referenced by ISO 20474 series.
These complementary documents help ensure a holistic approach to grader safety, from design and manufacturing through to operation and maintenance.
