Shelton and Belfair are covered here for death cleanup, trauma and crime scene cleanup, and biohazard cleanup. Biohazard and trauma cleanup in Mason County is done by independent private companies that a family, landlord or property manager hires directly. When a death is involved, the Mason County Coroner1 comes first, and cleanup can begin only after the scene is released. Biohazard Network connects you with an independent local company; we do not do the cleaning, and you hire and pay that company yourself.
A biohazard is biological material, such as blood or other body fluids, that can carry germs harmful to people. Trauma cleanup means safely removing that material, and anything it has soaked into, after a death, injury or crime. This page explains which county offices may be involved, how the roads affect a company reaching the property, and where to find help when hoarding is part of the picture.
The coroner comes first
Mason County uses a coroner system. A coroner is the county official who looks into certain deaths and decides how and why they happened. The Mason County Coroner1 determines and certifies the cause and manner of death for deaths from any unnatural cause, sudden deaths of people in apparent good health and not under a doctor’s care, suspicious or unexplained deaths, and unattended deaths, among others.
Scene release is the point when the coroner or police tell you they have finished with the property. Until then, please do not clean, move items or throw anything away. Once you have the release, it helps to arrange cleanup soon, because contamination left in place can spread into more materials. If you have a question about a death the office is handling, you can reach the Mason County Coroner1 at 360-427-9670 ext 752.
Autopsy reports are confidential, but under RCW 68.50.105 the person’s personal representative and any family member may examine them and get copies. When you need death certificates, copies come from Mason County Public Health2 and the Washington State Department of Health (DOH).
When the county health department may matter
Mason County Public Health and Human Services2 is the county health department, and its general line is 360-427-9670 ext. 869. Its programs come into play in a few specific situations.
Needles and sharps
Sharps are needles, syringes and other items that can pierce skin. The department’s guidance says home-generated needles and syringes may go in regular household garbage if they are in a firm plastic container sealed with duct tape and labeled “SHARPS, DO NOT RECYCLE”. If needles are mixed with blood or spread through a home, leave them for the cleanup company. Washington law uses the term biomedical waste for a set list of materials that includes discarded human blood and sharps waste, so ask the company how it will package and dispose of what it removes.
Sewage and septic
A sewage backup inside a home is a biohazard cleanup job of its own. If a failing septic system is the cause, the department’s On-Site Sewage System Program handles onsite sewage enforcement, including complaints and other sewage-related violations.
Outside the home, drug labs and mold
The Solid Waste Program, part of Environmental Health, takes neighborhood complaints such as garbage accumulated in bags outside a residence, and it states that owners, operators and occupants are responsible for legal disposal of solid waste on the property. That matters to landlords. The department also lists a Methamphetamine Labs program, so if you think a property was used to make drugs, contact the department before anyone starts cleaning. For mold questions, the county refers people to the DOH indoor air quality phone line.
When hoarding is involved
Hoarding is a recognized condition, and cleanup tends to go better when the person living in the home takes part in the decisions. Ask any company how it will sort belongings with the person or family, and how it handles what the person decides to let go.
The Humane Society of Mason County is a nonprofit animal welfare organization serving the whole county, and it lists rescuing animals from hoarding situations among its work. In Shelton, urgent animal-related help after shelter hours goes through MACECOM non-emergency dispatch. If the person is an older adult, the Lewis-Mason-Thurston Area Agency on Aging (LMTAAA) has a Mason County Office that sees people by appointment only.
How the roads shape the trip to a property
Mason County reaches from the Olympic Mountains to the inlets of Puget Sound, and it includes a shoreline drive along narrow, hook-shaped Hood Canal. That spread matters when a company is coming from elsewhere in the region. The stretch of US 101 that ends at Shelton is the only north-south route on the east side of the Olympic Peninsula. SR 3 links Shelton and Belfair and gives direct access between Mason and Kitsap counties, but it is mostly a two-lane undivided highway. SR 106 runs east to west for 21 miles between Skokomish and Belfair, and SR 119 is a two-lane road with narrow shoulders from Hoodsport to Lake Cushman.
When you contact a company, give the exact location, the nearest highway, and any notes about driveways or gates, then ask when it can realistically reach you.
Communities in Mason County
Shelton is an incorporated city where SR 3 meets US 101, with a downtown along Railroad Avenue of historic homes and businesses. It is about 20 miles from Olympia.
Belfair is an unincorporated community where SR 106 meets SR 3, and SR 300 links it to Belfair State Park and Tahuya.
Hoodsport sits where SR 119 leaves US 101, with a four-block downtown along the Hood Canal shoreline.
Insurance and the work after cleanup
Homeowners insurance sometimes covers biohazard cleanup, so read your policy and call your insurer before work begins. Ask the company whether it can provide the written scope and photos your insurer may want, whether it can bill the insurer directly, and whether it can use unmarked vehicles if privacy matters to you. Cleanup can also leave a home needing repairs, and our page on how biohazard cleanup fits with water, fire and mold restoration explains that next stage.
Usually covered: Homeowner insurance protects your home and belongings from damage caused by specific risks, says the Insurance Commissioner’s page on how home insurance works3. Personal property coverage includes your furnishings and personal items, such as your TV, clothing and dishes, the same page says.
Usually not covered: Exclusions in home contracts may include certain events, such as flood or earthquake, says the Insurance Commissioner’s insurance glossary4. Standard homeowner policies also do not cover sewer or drain backups, says the Commissioner’s page on being underinsured5.
Ask your insurer: “Without filing a claim yet, can you tell me if my policy covers biohazard cleanup in my home, and what limits apply?” Source: Filing a homeowner insurance claim (Washington State Office of the Insurance Commissioner)
Checking a company yourself
Before you hire, ask how the company’s workers follow OSHA’s bloodborne pathogens standard, 29 CFR 1910.1030 (bloodborne pathogens are germs in blood that can cause disease), and the ANSI/IICRC S540 Standard for Trauma and Crime Scene Cleanup from the IICRC, a non-profit organization for the inspection, cleaning and restoration industries, then look the business up in the Department of Labor & Industries (L&I) tool called Verify a Contractor, Tradesperson or Business. Our guide to biohazard cleanup certifications explained shows what each of these means and how to read what you find.
