Health hazards from the regulators: one list by country and topic

This page reports what the official source says. It is not legal advice: ask the office named here. Each row is one page, so a reader can see which regulator has written what. Most pages are general workplace pages. The two written for tree work are the UK Health and Safety Executive pages and the SafeWork NSW tree work page. A date appears only where the page shows one; otherwise the row says no date shown. The guide to health hazards of tree work covers ticks, poison ivy, noise and vibration in more detail, and the figures makers declare are on saw noise and vibration values.
