IS 17031 : Part 1 : 2024/ISO 11228-1 : 2021 Ergonomics - Manual Handling - Part 1 Lifting, Lowering and Carrying
NATIONAL FOREWORD
This Indian Standard (Part 1) (First Revision) which is identical to ISO 11228-1 : 2021 'Ergonomics - Manual handling - Part 1: Lifting, lowering and carrying' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Ergonomics Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 2018 based on ISO 11228-1 : 2003. This revision has been undertaken to align it with the latest version of ISO 11228-1.
The major changes incorporated in this revision are as follows:
a) The scope now covers lowering while the previous edition only covered lifting and carrying;
b) The risk estimation method has been made more comprehensive and considers more factors, such as the load asymmetry, the hand distance from the body, the vertical travel distance, the coupling quality, and the task duration;
c) It provides more guidance on risk reduction measures, such as the ergonomic design of work, the object and the environment as well as training and education; and
d) Addition of Annex D to Annex I to include updated information on expansions of the revised NIOSH lifting equation (RNLE), more examples for lifting and carrying, and detailed information on the scientific background and recommended interpretation of the RNLE.
This standard has been published in 3 parts. Other parts in this series are:
Part 2 Pushing and pulling
Part 3 Handling of low loads at high frequency
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however , not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
