Hierarchy of control for confined space Hazard
A confined space is defined as a space that is large enough to enter, has limited or restricted means of entry or exit, and is not designed for continuous occupancy. Hazards include atmospheric (toxic, flammable, oxygen-deficient), engulfment, entrapment, and others. Here is the Hierarchy of Controls for Confined Space Hazards, from most to least effective. The Hierarchy of Controls for Confined Spaces 1. Elimination The most effective control. Physically remove the hazard. · Description: This involves avoiding the need to enter the confined space altogether. · Examples: · Using a long-handled tool or a robotic arm to clean or perform tasks from outside the space. · Designing new equipment without confined spaces (e.g., open-top tanks, easily accessible pipelines). · Modifying the process so that internal work is no longer necessary. Effectiveness: Highest. If the worker never enters the space, they are not exposed to its inherent hazards. 2. Substitution Replace t...
