Code of Practice [1]

These are industry specific documents which offer guidance on good working practice. If the Health and Safety Executive has not produced an Approved Code of Practice, then an industry code of practice would be a reasonable approach to follow.
An example of a this is the ‘Code of Practice for Using Plant Protection Products’.
A code of practice is not legally binding, but it does show good practice and an individual or organisation would need to demonstrate good reasons why they did not follow recognised codes of practice if they were involved in a workplace accident.
Ignorance of relevant codes of practice would not usually be an acceptable defence in any legal proceedings.
