1. When is work considered work at height and when must a worker wear a harness?
Short answer: under § 105 of the Polish general occupational safety regulation, work at height is work performed on a surface at least 1.0 m above floor or ground level. Work on a surface enclosed on all sides by solid walls at least 1.5 m high, or protected by other permanent structures preventing a fall, is not treated as work at height.
A harness is not the first choice but a complement. The regulation first requires collective protection — guardrails with a top rail at least 1.1 m high, a toe board and an intermediate rail, nets, platforms and mobile elevating work platforms. Only where collective protection cannot be used does the employer provide fall protection equipment matched to the task and the anchor point.
The Polish Labour Code adds that the employer supplies PPE meeting conformity assessment requirements free of charge (art. 237⁷), informs workers how to use it, and must not allow anyone to work without the required protection (art. 237⁹). Work at height usually also requires a valid medical certificate covering this factor and, in many plants, a written permit to work.
