Power plant and utility buildings cleaned on the host’s terms
Janitorial service for the buildings at power plants, substations and utility service centers in the Bay Area and the Sacramento region, with access, escorts and off-limits areas set by the site’s own rules.
Janitorial care for the buildings around the plant
Fieldstone cleans the buildings people work in at generating stations and utility sites: administration offices, control buildings, warehouses and maintenance shops, substation control houses and utility service centers. The plant or utility, as host, decides which areas cleaners may enter, when, and with what escort, and the cleaning plan is built on those decisions.
Plant facility, maintenance and EHS managers get offices, break rooms, restrooms and shop floors kept in order without adding risk around operating equipment.
Where crews work, building by building
| Building | Cleaning on the plan | What the host controls |
|---|---|---|
| Administration offices | Desks, conference rooms, kitchens, restrooms, floors and trash | Building access and hours |
| Control buildings | Break rooms, restrooms, corridors and office areas around the control room | Which rooms are open, and when, on a 24-hour operation |
| Warehouses and maintenance shops | Concrete floor sweeping and scrubbing, high dusting, break and locker rooms | Traffic lanes, locked-out equipment and posted spaces |
| Substation control houses | Floors, restrooms and break areas outside rooms with energized equipment | Check-in with the employee in charge, escorts |
| Utility service centers | Offices, dispatch areas, locker rooms, training rooms and restrooms | Shift changes and yard access |
Offices follow our office cleaning routine. Warehouses and shops use the same methods as our industrial and warehouse cleaning, and periodic strip and refinish or concrete scrubbing runs through commercial floor care.
The host’s briefing comes first
OSHA’s power generation standard (29 CFR 1910.269) calls the plant or utility the host employer and an outside firm the contract employer. Before work starts, the host shares the installation’s characteristics and known hazards; the contractor passes them to its crew, tells the host about any hazards its own work brings, and reports anything unexpected it finds within 2 working days. California’s high-voltage safety orders also require employers sharing a high-voltage site to exchange hazard and procedure information first.
In practice, our supervisor walks the site with your EHS or facilities contact, the crew completes your orientation and wears the PPE you require, and the cleaning plan lists every room on the route, every room off it, and the rules for each.
Rooms with energized equipment
Under 1910.269, rooms holding electric supply equipment are enclosed or guarded and signed, unqualified people stay out of them while the equipment is energized, and only qualified employees work near exposed energized parts. In California, Title 8 treats anything over 600 volts as high voltage and reserves work on energized high-voltage equipment for qualified electrical workers.
Cleaning crews are not qualified electrical workers, so switchgear rooms, energized yards, boilers and condensers stay with your qualified staff. Crews clean the offices, corridors and support rooms around them, and enter any posted area only under your rules and with your escort.
Locks, tags and posted spaces
OSHA’s lockout/tagout rule (29 CFR 1910.147) counts cleaning as servicing, and it requires anyone working where lockout is used to know never to restart locked or tagged equipment. A tag is a warning device that is never removed without authorization or ignored. When outside contractors are on site, both employers share their lockout procedures.
Permit-required confined spaces, such as tanks, vaults and pits with serious hazards, are posted with danger signs, and the host must tell contractors where they are. Crews leave locked and tagged equipment exactly as found, stay out of posted spaces, and report anything that looks out of place to your contact.
Escorts and visitor logs at secured perimeters
Some utility sites protect control systems under NERC’s CIP-006 standard. It binds the utility, not the cleaning contractor, and its plan requires visitors without authorized unescorted access to be continuously escorted inside a Physical Security Perimeter, with entry and exit times, the visitor’s name and the escort’s name logged and kept at least 90 days.
The plan builds that time in. Crews arrive at the set hour, sign in, stay with the escort and finish inside the perimeter in one pass, so the escort’s time is used well. Fieldstone’s cleaners are background-checked, and your site’s access program decides who goes where.
Shifts, outages and outside work
Control rooms and dispatch run around the clock, so their restrooms and break rooms are cleaned at the quietest hours your team names. Heavier jobs, such as high dusting from lifts over warehouse racking or a shop floor refinish, wait for windows the host sets, including planned outages.
Exterior glass on low-rise buildings is cleaned through our commercial window cleaning, keeping poles and lifts well away from overhead lines. Title 8 sets general minimum clearances, such as 6 feet from lines of 600 to 50,000 volts and 10 feet above 50,000 up to 345,000 volts. We serve plant and utility buildings throughout our area, from Fremont and Concord to Rancho Cordova and Sacramento.
Request a plant cleaning quote
Fieldstone holds insurance, bonding and workers’ compensation coverage, supervisors check the work with quality inspections, and a certificate of insurance goes into your contractor file. The quote reflects the buildings on the route, square footage, visit frequency, escort and sign-in time, orientation and PPE steps, and any outage work. Request a quote and we will walk the site with your team.
A few useful answers
Common questions
What does your crew need from us before the first visit?
Your hazard briefing, site orientation, PPE requirements and a list of the rooms on the route and off it. Our supervisor walks the site with your contact and the plan records each of those rules.
Will cleaners enter rooms with energized equipment?
Only where your rules allow it and with your escort. Switchgear rooms, energized yards and similar posted areas stay with your qualified workers, and crews clean the offices and support rooms around them.
What does the crew do if it finds a lockout tag in the shop?
Leaves the equipment exactly as it is and cleans around it. Crews never remove a tag or restart locked equipment, and anything unusual is reported to your contact.
Our perimeter requires escorts and a visitor log. How does that fit the schedule?
Escort and sign-in time is part of the plan. Visits are booked at set hours and the work inside the perimeter is done in one pass, so your escort is not tied up longer than needed.
When does heavier floor work happen at a plant that never stops?
In the windows your team sets, such as a slow shift or a planned outage. Daily cleaning keeps going in the meantime, and the plan lists which jobs wait for which window.
