Overview

ISO 8437-2:2019 - Snow throwers - Safety requirements and test procedures - Part 2: Pedestrian-controlled snow throwers specifies safety requirements and verification methods for combustion engine powered pedestrian-controlled snow throwers. Intended to be used together with ISO 8437-1 and ISO 8437-4, this Type‑C machinery standard addresses significant hazards, hazardous situations and events relevant to snow throwers used as intended and under reasonably foreseeable conditions. It replaces the earlier ISO 8437:1989 edition.

This standard excludes electrically or battery powered and hand-held snow throwers, airport/highway snow-removal machinery, machines for explosive atmospheres, and does not cover certain electrical/system hazards (e.g., battery circuits >42 V, mains starting motors, magneto grounding circuits), working environment or electromagnetic compatibility beyond specified immunity tests.

Key topics and requirements

ISO 8437-2:2019 covers practical, testable safety provisions, including:

Operator controls and layout
- Controls must be within defined operator control positions and usable with arctic mittens.
- Controls must not be located in hazard zones (collector/discharge zones).
- Clear labeling and instructional information for non‑obvious controls.
Engine starting and stopping
- Requirements for starter devices (e.g., key switches) to prevent unauthorized starting.
- Stopping devices that do not rely on sustained manual pressure.
- Drive interlocks to prevent starting when collector/impeller or traction drives are engaged.
Guards, chutes and hot surfaces
- Protection for collector, impeller, discharge chute, deflectors, housings and hot surfaces.
- Provision for safe snow clean-out tools.
Fuel system tests
- Fuel tank overfill testing and fuel line axial pull tests to reduce leak and fire risks.
Electrical and battery‑related safety
- Insulated cables, battery installation, overload protection, terminals and non‑insulated parts (battery circuits not exceeding 42 V).
Mechanical and performance tests
- Power drive assessments, probe tests for access hazards, electromagnetic immunity checks, noise and vibration requirements.
Documentation
- Instruction handbook, markings and warnings; Annex A provides handbook content requirements.

Applications and users

ISO 8437-2:2019 is used by:

Snow thrower manufacturers (design, R&D, compliance testing)
Product safety and certification bodies
Regulators and market surveillance authorities
Maintenance and service organizations
Occupational safety professionals

It helps ensure safer pedestrian-controlled, combustion-engine snow throwers through design guidance, test procedures and required user information.
