It is confined-space work. Ventilate, test the air if you can, use a harness and a person outside, and never enter alone. **Q: How should I price it?** A: By tank capacity or size, number of tanks, access (overhead or underground), sludge level and travel. Yearly contracts with a fixed number of cleanings are easier to plan. ## Related articles [Cleaning & Housekeeping Housekeeping Duty Roster Format for Cleaning Contractors Housekeeping duty roster format for cleaning contractors: staff, shifts, areas, weekly offs and relievers by day, for each client site.
