Overview
ISO 1819:1977 - "Continuous mechanical handling equipment - Safety code - General rules" is the first-edition International Standard that defines essential safety rules for continuous mechanical handling equipment (conveyors) used for loose bulk materials and unit loads. Published in 1977 and replacing ISO Recommendation R 1819‑1970, the standard covers design, construction, installation, operation and maintenance to prevent accidents and ensure legal compliance in countries where such requirements are mandated.
Key topics and technical requirements
ISO 1819 focuses on practical safety measures for conveyor systems and related equipment. Major topics include:
- Scope and definitions - Normal working conditions, personnel classifications, and limits of supplier responsibility (excludes building structures unless supplied by the conveyor manufacturer).
- Design and construction
- Ensure stability and strength under agreed climatic and working conditions.
- Prevent spillage, slipping, unintended dropping and over‑running; provide anti‑rollback devices on inclined/vertical systems.
- Protect in‑running nips, pinch points, shearing/squeezing zones and moving parts with guards or interlocks.
- Design access panels and inspection openings so they are locked or require tools to remove; ensure lubrication points are accessible without removing guards.
- Installation and erection
- Provide safe gangways, stairways, platforms and fixed access (minimum passageway recommendations, guard‑rails, toe‑guards).
- Sequence interlocks to prevent feeding inoperative or overloaded equipment; audible/visual warnings where operators lack line‑of‑sight.
- Permanently mark manufacturer, year and serial number.
- Operation and maintenance
- Limit equipment use to intended duties; supply clear loading instructions and permissible unit loads.
- Permit only authorized personnel for start/stop and maintenance; require inspections before restart after emergencies.
- Regular cleaning, lubrication and maintenance per manufacturer’s instructions; prohibit opening inspection holes while running unless compliant with guarding rules.
Applications and users
ISO 1819 is applicable to a wide range of continuous handling systems including belt conveyors, chain conveyors, elevators and mobile conveyors for bulk materials and unit loads. Typical users:
- Conveyor and material‑handling equipment manufacturers and designers
- Plant engineers, installation contractors and erectors
- Safety managers, maintenance teams and facility operators
- Regulatory authorities specifying compliance with national safety laws
Related standards
- ISO/TR 5045, ISO/TR 5046, ISO/TR 5047 (technical reports giving guarding examples and additional guidance for belt and chain conveyors)
- Special ISO standards addressing specific conveyor types and conveyors designed to carry people
