Overview

What this SWMS covers

Inflatable amusement devices include bouncy castles, slides, obstacle courses, and play structures that require careful installation, anchoring, and supervision to prevent accidents. The work involves site preparation, electrical setup for blowers, anchoring systems to resist wind displacement, safety perimeter establishment, and emergency procedures. Installation typically occurs outdoors at events, schools, or recreational facilities, requiring assessment of ground conditions, weather monitoring, and proximity to hazards like power lines or trees. Workers must be competent in inflatable device operation, emergency deflation procedures, and crowd management. The devices rely on continuous air pressure from electric blowers, creating risks from power failures, motor overheating, or electrical faults. Safety procedures include maximum capacity limits, supervision requirements, and rapid evacuation protocols for sudden deflation or structural failure. Regular inspections and maintenance prevent fabric tears, seam separation, or blower malfunction that could lead to collapse during use.

Why this SWMS matters

Inflatable amusement devices pose significant risks to both workers and the public due to their lightweight construction and reliance on air pressure for structural integrity. Serious incidents have occurred from inadequate anchoring causing wind displacement, structural failure from fabric damage, overcrowding leading to falls or entrapment, and supervision failures allowing unsafe behavior. The Work Health and Safety Act 2011 classifies certain inflatable devices as high-risk plant requiring design registration and regular inspections under AS 3533.4.1. Workers face hazards during installation including working at heights for anchoring, manual handling of heavy equipment, electrical risks from blower systems, and exposure to weather extremes. Public safety requires strict supervision, capacity limits, and emergency procedures to prevent overcrowding, collisions, or sudden deflation. Without comprehensive SWMS procedures, operators risk serious harm from equipment failure, improper setup, or inadequate safety measures. This SWMS ensures systematic risk assessment, implementation of engineering controls like proper anchoring systems, administrative controls including supervision requirements, and PPE for workers to maintain compliance and prevent incidents.
