When preparing for entry into a confined space, you may need the following equipment:

• Ventilation
  • Does the space have potential for a hazardous atmosphere? If so, the space needs to be ventilated.
• Permits
  • A confined space permit needs to be filled out and reviewed by the entry supervisor, the entrants and observers.
• Testing Equipment
  • Air monitoring must be conducted prior to and during entry
  • Results are recorded on the confined space permit
  • All levels of the space need to be tested (top to bottom)
    • Some gases float and others pool
  • Testing needs to be done for oxygen content, lower explosive limits (LEL), hydrogen sulfide and carbon monoxide, at a minimum.
• Personal Protective Equipment (PPE)
  • Special PPE is sometimes required
  • If the space is a permit-required confined space, then a harness and retractable lifeline may be required, so that rescue can be done without entering the space.
  • Respirator protection
  • Specialized clothing/gloves/boots
    • Protect against contamination, lacerations and potential falls

• Communication equipment (walkie-talkie, cell phone if non-flammable atmosphere)
• Audible or visual alarms
• Fire extinguisher
• Explosion-proof lighting
• Rescue and retrieval equipment
• Ventilation equipment
• Barriers, shields and signs
