**Hierarchy of Hazard Controls:**

– **Elimination:** Physical removal of the hazard is the most effective control method.
– **Substitution:** Involves replacing a hazardous agent with a safer alternative.
– **Engineering Controls:** Do not eliminate hazards but isolate people from them.
– **Administrative Controls:** Changes to work procedures and practices to limit exposure.
– **Personal Protective Equipment (PPE):** Includes various gear like gloves, helmets, and respirators.

**Prevention through Design:**

– Core component of Prevention through Design.
– Emphasizes addressing hazards early in the design process.
– Focuses on elimination and substitution at the earliest project stages.

**Variations on the NIOSH Control Hierarchy:**

– Different structures used in various countries or entities.
– Some variations include isolation above engineering controls.
– ARECC framework includes modification of materials or procedures.
– Warnings are sometimes part of engineering or administrative controls in different systems.
