Safety & Compliance

Q: Can you provide a certificate of insurance?

Yes. Certificates of insurance are available on request for any project.

Gullwing takes safety and professional standards seriously on every project, whether the site is an active construction zone with heavy equipment and truck traffic, a commercial property with pedestrians and tenants, or a public roadway with live traffic lanes.

The company is fully licensed and insured, and every crew member goes through specialized training programs with NAPSA (the North American Power Sweeping Association) to ensure they are equipped to work safely in the conditions each jobsite presents.

OSHA 30 Construction Certification

Gullwing employees hold OSHA 30 construction certification, the 30-hour training program administered by the Occupational Safety and Health Administration. The curriculum covers hazard recognition, fall prevention, electrical safety, scaffolding safety, personal protective equipment requirements, struck-by and caught-between hazard awareness, and the general safety practices required to work on active construction sites alongside other trades.

OSHA 30 is not a checkbox. It is the baseline that allows Gullwing crews to operate on jobsites where general contractors require documented safety training before any subcontractor or service provider sets foot on the property. Many active construction sites in the Puget Sound region require OSHA 30 as a condition of site access.

Our Regular Safety & Compliance Practices

Crews arrive with the PPE each site requires. Standard gear includes high-visibility apparel (Class 2 or Class 3 vests as conditions demand), hard hats, safety glasses or eye protection, hearing protection for high-noise environments, and steel-toed or safety-rated footwear. When general contractors or property managers specify additional site-specific PPE requirements, Gullwing crews comply before entering the work area.

Sweeper operators and crew members are trained to maintain awareness of vehicle traffic, pedestrian movement, changing site conditions, and hazards specific to construction environments and public roadways. On active construction sites, this means coordinating with site superintendents and flaggers, staying clear of crane operations and overhead work, and adjusting routes when site conditions change during a shift. On public streets and commercial properties, it means managing sweeper routes to avoid conflicts with vehicle traffic, pedestrians, and business operations.

Gullwing is fully licensed and insured. The company maintains current general liability insurance, commercial auto insurance, and workers' compensation coverage. Certificates of insurance are available on request for any project and can be issued naming additional insureds when required by general contractors or property owners.

When requested, Gullwing provides route logs showing where sweepers traveled, when service was performed, route times, and coverage areas. Route logs serve as documentation for stormwater compliance records (SWPPP reporting), property management maintenance logs, municipal contract verification, and construction project documentation where the general contractor needs a paper trail showing that sweeping was performed on specific dates and routes.

Safety Data Sheets (SDS) are available for any cleaning agents, degreasing products, or chemical materials used during pressure washing, dumpster pad cleaning, or other service work. SDS documents describe the products used, their chemical composition, associated hazards, and safe handling, storage, and disposal guidance.

In addition to maintaining OSHA 30 certification, crew members undergo specialized training programs through NAPSA (the North American Power Sweeping Association) alongside equipment-specific instruction. This covers sweeper and water truck operations, traffic management during mobile work, proper debris handling and disposal, and jobsite safety protocols. Training is an ongoing priority—regularly refreshed to account for new fleet equipment, updated regulatory standards, or unique site requirements.
