Substitution: Replacing hazardous substances with less harmful alternatives is ideal. For example, using water-based solvents instead of volatile organic compounds. Engineering Controls: Implementing physical changes to processes, such as ventilation systems or containment barriers, can reduce exposure to hazardous substances. Administrative Controls: Changing work procedures and policies, such as limiting exposure time or rotating shifts, helps minimize risk. Personal Protective Equipment (PPE): When other controls are insufficient, PPE like gloves, masks, and goggles can protect individuals from exposure.
