Confined Space Entry Procedures

Purpose

Ensure Spartan Plumbing technicians follow safe procedures when entering confined spaces such as crawlspaces, attics, large trenches, utility vaults, and any space with limited entry/exit.

When to Use

• Entering any crawlspace, attic access, or below-grade vault
• Working in any space with limited entry and exit points
• Trenches deeper than 4 feet
• Any enclosed space where air quality may be compromised

Procedure

Before Entry

Assess the space — can you identify the entry and exit points?

Test for hazardous atmosphere if possible (CO meter at minimum for spaces near gas appliances)

Ensure adequate ventilation — if the space is enclosed with no airflow, set up a fan or blower

Inform someone on-site or at dispatch that you are entering a confined space and your expected time

Have your phone accessible and charged

Ensure you have the right PPE: knee pads, gloves, safety glasses, N95 mask, flashlight/headlamp

During Work

Monitor for signs of bad air: dizziness, headache, nausea, unusual odors

If you feel ANY symptoms of bad air, exit immediately

Keep your exit path clear at all times — do not block it with tools or materials

Do not exceed your physical limits — crawlspaces and attics are physically demanding

Stay hydrated, especially in hot attics during summer

Emergency — Feeling Unwell or Trapped

Exit the space immediately if you feel dizzy, nauseated, or short of breath

If you cannot exit, call 911 and your supervisor

Do NOT have an untrained person enter the space to rescue you — wait for fire/rescue

Move to fresh air as soon as you exit

Crawlspace-Specific Guidelines

• Check for standing water, pests, and structural hazards before entering
• Use a drop cloth to protect your clothing and the customer's access area
• Never work alone in a crawlspace if there is standing water or sewer exposure
• Take photos of conditions before and after your work

Attic-Specific Guidelines

• Check the attic temperature before extended work — attics in Ohio summers can exceed 140 degrees F
• Limit attic work to 15-20 minutes at a time in extreme heat, then come down to cool off
• Walk only on joists or rated platforms — never step on drywall ceilings
• Ensure the attic access hatch is fully open and not obstructed

Important Notes

• If a space is too dangerous to enter (flooding, collapsed structure, strong chemical smell), do NOT enter — call your supervisor and explain why
• Spartan does not require permits for most residential confined spaces, but use common sense about safety
• If you are uncomfortable entering a space, you have the right to refuse and discuss alternatives with your supervisor
