**Manual lancing** is operator-performed cleaning of industrial equipment using handheld rods, lances, water jets or hammers. In modern industrial practice it is the cleaning method of last resort — performed when automated cleaning systems have failed to prevent build-up that now requires direct human intervention.

## Where it persists

- Cement-plant [kiln-inlet snowman](/glossary/kiln-inlet-ring-snowman) removal during planned outages
- [Recovery-boiler](/glossary/recovery-boiler) post-water-wash inspection cleaning
- [Hopper](/glossary/hopper) and [silo](/glossary/silo) clearance after bridging-induced shutdowns
- Cleaning of partially-blocked equipment too restricted for water-jet access

## HSE concerns

- Confined-space entry
- Elevated working positions
- Fall-of-material risk above operators
- Heat exposure
- Repetitive-strain injury from sustained manual work

The economic and HSE case against manual lancing is the underlying motivation for installing automated cleaning systems including [sonic horns](/glossary/sonic-horn) — every avoided manual-lancing campaign removes an HSE-exposed operator-hour from the maintenance budget.
