Confined Space Hazard Controls

Engineering, administrative, and personal protective equipment (PPE) controls are essential measures for managing hazards in confined spaces. Here is a brief list and description of these control measures:

Confined Space Hazards

Engineering Controls

  • Ventilation Systems: Implement mechanical ventilation systems to ensure adequate airflow and control the levels of hazardous gases, vapors, or dust in the confined space.
  • Isolation Barriers: Use physical barriers to isolate the confined space from other work areas, preventing unauthorized entry and controlling access.
  • Lockout/Tagout: Utilize lockout/tagout procedures to isolate energy sources and prevent the accidental activation of equipment or machinery inside the confined space.

Warnings/Administrative Controls

  • Warnings: Posting warning signs prohibiting entry into confined spaces and areas.
  • Permit Systems: Implement a permit system, such as a confined space entry permit, to control access and ensure that proper precautions are followed before workers enter the confined space.
  • Entry Procedures: Develop and enforce clear and specific entry procedures, including pre-entry checks, hazard assessments, and communication protocols.
  • Training and Education: Provide comprehensive training to workers involved in confined space entry, focusing on hazard recognition, emergency procedures, and safe work practices.

Personal Protective Equipment (PPE) Controls

  • Respiratory Protection: Provide appropriate respiratory protection, such as respirators, to workers based on the specific contaminants and oxygen levels present in the confined space.
  • Protective Clothing: Supply workers with protective clothing, such as coveralls or chemical-resistant suits, to prevent exposure to hazardous substances.
  • Fall Protection: Use fall protection equipment, such as harnesses and lanyards, if there is a risk of falling from heights within the confined space.
  • Hand and Foot Protection: Ensure workers wear suitable gloves, safety shoes, or boots to protect against potential hazards, such as chemicals, sharp objects, or electrical hazards.

The selection and combination of all of the hierarchy of controls is necessary to adequately ensure hazards are controlled and that confined spaces are safe to enter. Compliance with applicable regulations, industry standards, and best practices is crucial to ensure the safety of workers in confined spaces.
